Description

  The present invention relates to an attachment that is used by being attached to a tea garden management device in order to extend a tea garden management function, and a teacup straddle type tea garden management device having the attachment.

In tea cultivation work, various tea garden management (work) prior to plucking work is important to obtain a favorable harvest. This tea garden management includes pruning work to guide the tea tree to a suitable tree shape and shape for harvesting, fertilizing work to replenish nutrients deficient in natural supplies as fertilizer, pest control work, etc., including deciduous trees In tea gardens (farm fields) where miscellaneous forests and the like are in close proximity (see FIG. 1), it is also an important tea garden management work to remove the litter that has fallen on the tea bowl.
In order to remove such fallen leaves, a form of blow-off with a shoulder-type blower can be considered, but unlike the work of removing fallen leaves that fell on the ground (shoulder) with a blower, the fallen leaves on the teacup are tea trees. In many cases, it cannot be removed smoothly with a blower. In addition, even if you can blow the litter leaves on the teacup with a blower, it does not always conveniently fall into the furrow (butterflies), and often falls on the teacups (changes) again. Therefore, removing the litter on the tea bowl with a blower was not a realistic method. For this reason, the work of removing the litter on the tea bowl is left to the work, which is extremely time-consuming, and no effective countermeasure device has yet been provided.

In addition to these problems, the following problems have been solved in the work of finishing pruning, called makeup mowing (finishing mowing), etc., performed before the germination, as a solution for tea garden management. there were. In other words, when performing trimming with a clipper type cutting blade, for example, as shown in FIG. 9, the cutting blade C cuts the tea tree while pressing the tea tree, so that the cutting surface becomes oblique. That was the problem.
Further, since the degree of inclination of the tea tree tilted by being pushed by the cutting blade C varies depending on the strength of the stem (the thicker and stronger the stem is, the smaller the tilt is), as shown in FIG. In many cases, the height of the mowing surface was different when the was recovered from the tilted state (unevenness was often generated on the mowing surface). In order to prevent this, for example, the height of the cutting surface can be made almost uniform by reciprocating, but such reciprocal cutting naturally requires twice as much work as a single mowing. It was necessary and increased the work load.

By the way, the present applicant has earnestly studied a new transfer method in which the tea branch leaves A 'after cutting are transferred by the action of the back wind W fed into the transfer duct 5' from the rear side of the cutting blade C. (See, for example, Patent Document 1). Incidentally, the present applicant refers to the transfer form by the back wind W as a slit-jet type, and uses this name hereinafter.
Further, in Patent Document 1, the tea branch leaves A ′ after cutting are not transferred by the rear wind W, but, for example, as shown in FIG. 10, the front plate 51 ′ (front adjustment plate 510) of the transfer duct 5 ′. ′) Is slidable up and down, and the opening (opening height) of the transfer start portion 5S ′ can be changed, thereby cutting the short-browned tea branch A ′ (this figure (a)), For example, when the long-branched tea branch leaves A ′ are cut (this figure (b)), the tea branch leaves A ′ are reliably cut according to the conditions.
However, the front plate 51 ′ (front adjustment plate 510 ′) of this Patent Document 1 is exclusively considered for adjusting the cutting height when the tea leaves A ′ are plucked, and is used for other tea garden management work. There was no idea to apply to.

  The above-mentioned tea garden management work is remarkably different from the operation purpose and work form, and has no context. As a result of taking into account the above-mentioned slit-jet type transfer mode that has recently become widespread, the present inventor has found that this unique transfer action, and the cutting blade associated therewith. The idea was that the above problems could be solved in common by focusing on the structure in which the member for supplying the transfer air does not exist in front and devising the structure around the cutting blade.

JP 2008-35706 A

  The present invention has been made in view of such a background. The slit-jet type transfer mode, which has been used for the transfer of the tea leaves that have been cut, has been further improved. The present invention relates to a novel attachment that is actively used to maintain the tea plant posture at the time, and a teacup crossing-type tea garden management device to which this is applied.

The attachment is attached to the front adjustment plate in a fixed state.

Further, the attachment for expanding the tea garden management function according to claim 3 is in addition to the requirement according to claim 1 or 2,
The attachment comprises a substantially flat plate-like member as a main member, and the plate-like member is formed in a shape substantially matching the shape of the teacup front view when viewed from the front. It consists of.

The attachment for expanding the tea garden management function according to claim 4 is in addition to the requirement according to claim 1, 2, or 3,
The apparatus provided with the transfer duct is characterized in that it is used for the operation of sucking and removing litter leaves placed on a teacup.

Further, the attachment for expanding the tea garden management function according to claim 5 is in addition to the requirement according to claim 1, 2, 3 or 4,
The apparatus having the transfer duct is a tea cutting apparatus having a cutting blade,
The suction effect of the back wind on the top surface of the teacup is such that the top of the tea tree forming the teacup is drawn toward the cutting blade side, and the top end of the tea tree is maintained in an almost upright state when the cutting edge of the tea tree is trimmed by the cutting blade. It is characterized by the fact that it is reaped.

Moreover, the teacup crossing type tea garden management device according to claim 6 is:
A traveling aircraft that travels across the bowl,
A device that is attached to the traveling machine body and includes a transfer device that sends a transfer object located on the upper surface of the teacup to an appropriate place,
The transfer device comprises a transfer duct for transferring an object to be transferred and a blower duct provided on the rear side thereof, and introduces a rear wind from the blower duct from the blow-in part of the transfer duct, whereby The object to be transferred is sucked and transferred to an appropriate place,
In addition, the attachment according to claim 1, 2, 3, 4 or 5 is attached to the transfer device, and the suction action exerted by the back wind on the upper surface of the teacup is enhanced.

  First, according to the first aspect of the present invention, in the slit-jet type transfer mode, for example, in order to reinforce the suction action of the back wind on the upper surface of the teacup by attaching the attachment, for example, fallen leaves falling on the teacup But it can be collected cleanly and efficiently. That is, the litter leaves that fall on the teacups are easily entangled with the tea plantation, for example, whether they are blown away with air or air suction, so they are not easily separated from the tea plant and are often difficult to remove. It was. In this respect, in the present invention, by attaching the attachment, the suction action by the existing back wind is strengthened, and thus even the above-mentioned fallen leaves can be removed cleanly and smoothly by air suction.

  According to the second aspect of the invention, since the attachment is mounted on the front adjustment plate of the transfer duct that can slide in the vertical direction, the vertical position of the attachment (by moving the front adjustment plate in the vertical direction ( The height can also be set easily. Also, since the attachment is attached to the front adjustment plate, which is a plate-like member, attachment can be attached relatively easily, reducing the work burden on the worker (farmer) who actually attaches / detaches the attachment. it can.

  According to the third aspect of the present invention, since the main member of the attachment is a substantially flat plate-like member, the structure of the attachment becomes simple, and the attachment can be manufactured easily and at low cost.

  Further, according to the invention described in claim 4, since the litter leaves that have fallen on the teacup are removed by the apparatus equipped with the attachment, the labor of the removal work is greatly reduced. That is, the fallen leaves placed on the tea bowl are often entangled with the tea tree, and even if it is blown off by a blower or sucked with air, the removal operation from the tea tree cannot be performed smoothly. For this reason, conventionally, the removal work has been left exclusively to human labor, and has been an extremely time-consuming work. In this respect, in the present invention, the litter and leaves on the teacup are sucked and removed by the suction force strengthened by the attachment, so that it can be removed cleanly and efficiently, and the work labor is greatly reduced. is there.

  According to the invention described in claim 5, since the makeup trimming is performed by the tea-cutting device equipped with the attachment, the top of the tea tree is drawn toward the cutting blade during the tea-cutting operation, and the trimming surface can be neatly aligned. .

Further, according to the invention described in claim 6, since the attachment is attached to the teacup-crossing type tea garden management apparatus that many tea farmers already own in individuals and groups, it is economical for tea farmers. It is possible to easily expand the functions of the existing teacup-climbing type tea garden management device without imposing much burden.
Thus, the attachment according to the present invention greatly expands the function (tea garden management function) of the conventional tea garden management apparatus.

This is a plucking method adopting the slit-jet type transfer form by the present applicant, in the case where the tea branch leaves of short buds are cut by a tea-cutting device provided with a front adjustment plate slidable up and down on the front side of the transfer duct. It is side surface sectional drawing (a) shown, and side surface sectional drawing (b) which shows the case where the tea branch leaves of a long bud are harvested with the tea-cutting device.

  The mode for carrying out the present invention includes one described in the following embodiments, and further includes various methods that can be improved within the technical idea.

The present invention, for example, efficiently sucks and removes the transfer object A such as litter leaves falling on the teacup T from the teacup T, and as an example, as shown in FIG. A teacup-crossing type tea garden management device 1 (hereinafter simply referred to as “tea garden management device 1”) that performs appropriate tea garden management work such as plucking while traveling across the teacup T is used. That is, the tea garden management device 1 often includes a transfer device 3 that transfers the picked tea leaves or the like to an appropriate place by air suction or air blowing. In other words, the transfer object A such as litter leaves located on the teacup T is sucked and removed. However, even if the existing transfer device 3 is simply used to try to suck and remove the fallen leaves as the transfer object A, the fallen leaves are difficult to remove because they are easily entangled with the tea tree. Therefore, in the present invention, by attaching the attachment 7, the suction force exerted on the upper surface of the teacup T by the rear wind W (pressure wind flowing in the transfer device 3) is enhanced, which is a major feature. . As a result, for example, litter leaves that tend to get entangled with tea trees can be collected cleanly and efficiently by a machine (transfer device 3) without depending on human hands.
Incidentally, in the present invention, the object to be removed / transferred from the teacup T (transfer object A) includes foreign matter (garbage) such as ash fall, insects, vinyl, etc. in addition to the fallen leaves and leaves. Is used to suck and remove from the bowl T.

In the present invention, the suction force exerted by the back wind W on the upper surface of the teacup T is strengthened only by mounting the attachment 7 (regulator 71). The transfer object A located on the ridge T is efficiently sucked and removed, or the tea leaves are cut. For this reason, the present invention is not necessarily limited to the tea cutting work (tea cutting specifications), and therefore, the tea cutting apparatus usually used for this work, more specifically, the cutting blade C is not necessarily an essential member. It is.
Of course, there is no problem with attaching the attachment 7 to an existing tea-cutting device. For example, when finishing pruning work is performed with a tea-cutting device equipped with the attachment 7, the suction force exerted on the upper surface of the teacup T is reduced. By strengthening, the tea tree posture at the time of pruning can be maintained, and a beautiful cut surface can be obtained. Specifically, for example, when makeup trimming of the upper end of the tea tree is performed by the cutting blade C, the teacup T is formed by the suction action that the back wind W exerts on the top face of the teacup T (by the enhanced suction action). The tea tree top can be pulled toward the cutting blade C side for trimming. Therefore, the upper end of the tea tree can be maintained in an almost upright state for cutting and the cutting surface can be neatly arranged.
As described above, in the present invention, by attaching the attachment 7, it is possible to perform the removal operation of the fallen leaves that could not be performed by the existing tea garden management device (there was no idea to do so), and the existing tea cutting device. If the attachment 7 is attached to the blade and trimmed, a clean cut surface can be obtained. Therefore, the attachment 7 according to the present invention greatly expands the tea garden management function of the existing tea garden management apparatus.

Here, the tea garden management work described in this specification will be organized. Examples of tea garden management work include plucking work, pruning work, control work, and fertilization work. Among them, the plucking work is a work of picking tea leaves (tea buds), and the pruning work is a work of pruning the trunks in order to prepare the tree shape and restore the vigor. The fertilization work is a work of supplying (spreading) nutrients that are insufficient in natural supplies as fertilizer, and the control work is a work of controlling pests by spraying with a chemical solution or the like.
In addition, plucking work and pruning work are collectively referred to as tea cutting work or pruning (work), and plucked tea leaves and pruned branch trunks are collectively referred to as tea branch leaves. . The plucking device and the pruning device are collectively referred to as a tea cutting device.

Hereinafter, the attachment 7 will be described while explaining the tea garden management device 1. In the following embodiments, a case where the litter leaves located on the teacup T are removed and collected by the suction force of the back wind W (the suction force enhanced by the attachment 7) will be described as an example. .
For example, as shown in FIGS. 1 and 2, the tea garden management device 1 appropriately sets a traveling machine body 2 that travels across the teacup T and a transfer object A that is attached to the traveling machine body 2 and is positioned on the teacup T. It comprises a transfer device 3 for transferring to a place. In the present embodiment, the storage unit 4 for collecting the transfer object A removed from the teacup T is further provided, but the transfer object A removed from the teacup T is stored in the storage unit 4 in particular. If it is not (recovered), guided to the ground by the transfer device 3 and dropped into the space, the housing part 4 is not particularly necessary. Of course, in that case, a transfer path or the like is separately configured so that the transfer object A removed from the teacup T is guided to the ground and dropped into the cage. Incidentally, regarding such a transfer form, the pruning branch trunk in the teacup straddle type tea-cutting device of Japanese Patent Application Laid-Open No. 2002-136214 (Patent No. 4596631), which has already been applied for and obtained a patent. Can be applied.
Hereinafter, each component of the tea garden management device 1 will be described.

  First, the traveling machine body 2 will be described. This is one that travels on the ground between the teacups T across the teacup T, and has a frame 21 that is formed in a gate shape when viewed from the running direction. The frame 21 includes a leg frame 21A provided in a standing state between the ribs, a connecting frame 21B that connects the leg frames 21A, and a lifting bracket 21C that is attached to the leg frame 21A so as to be movable up and down. Is. And the traveling body 22 which applied the crawler as an example is provided in the lower end of the leg part frame 21A. Of course, the traveling body 22 is not limited to such a crawler, but a form in which a pneumatic tire that does not excessively press the saddle, or both are applied (for example, a form in which a pneumatic tire is applied to the front side and a crawler is applied to the rear side). Etc. can be taken as appropriate.

Further, on the upper part of the connection frame 21B, a driver seat 23 on which an operator who has boarded the tea garden management device 1, a control stick 24 for operation, and a control box for controlling and operating the tea garden management device 1 are provided. 25. Next, a motor 26 to which, for example, a diesel engine is applied is mounted on the side of the driver's seat 23. As an example, a hydraulic pump (not shown) is driven by the motor 26 and supplied by the hydraulic pump. The traveling oil 22 is used to drive the traveling body 22, a cylinder (not shown) for raising and lowering the lifting bracket 21 </ b> C, or driving (actuating) a transfer device 3 described later.
In addition, as shown in FIGS. 1 and 2, a blower 27 is provided on the connecting frame 21B for sucking and removing (winding) a transfer object A such as a fallen leaf located on the teacup T. The blower 27 is directly driven by the prime mover 26.
Then, the pressure air is supplied from the blower 27 to the transfer device 3 through the relay duct 28. The relay duct 28 is partly or entirely formed by a flexible duct 28 </ b> F and connected to the transfer device 3.

Next, the transfer device 3 will be described. The transfer device 3 transfers a transfer object A such as deciduous leaves and the like located on the teacup T toward a predetermined position (accommodating portion 4 in this embodiment). The transfer device 3 includes a transfer duct 5 formed in a wind tunnel shape as a main member, sucks the transfer object A through the duct, and places the transfer object A on the air flow (air flow). To be transported to.
1-4, for example, as shown in FIGS. 1 to 4, the transfer duct 5 is formed so as to rise in a substantially vertical direction, and the transfer object A is accommodated by the air (back wind W) sent upward into the inside thereof. 4 is transferred. For example, as shown in FIG. 8A, the transfer duct 5 may be provided such that the upper part serving as a transfer destination is inclined slightly toward the rear side.
In this specification, terms such as “front” / “back” are used, which mean “front side” / “back side” of the tea garden management apparatus 1. For this reason, the “front side (front side)” corresponds in other words to the work progressing direction in which the tea plant management device 1 collects the transfer object A.

And the ventilation duct 6 is provided in the back side of such a transfer duct 5, By introducing the pressure wind (air) which flows through the inside of the ventilation duct 6 downward from the blowing part 50 of the transfer duct 5, it is upward. An upward air flow (upflow) is formed in the transfer duct 5.
Here, since the pressure air sent into the transfer duct 5 from the blower duct 6 is sent from the back side of the transfer duct 5, this is referred to as “back wind W” in this specification. Further, a portion where the back wind W is introduced from the blower duct 6 into the transfer duct 5 is referred to as a “blowing part 50”. Furthermore, as described above, the applicant of the present invention refers to such a transfer form by the back wind W as a slit-jet type, and this is referred to as a “slit-jet type transfer form” in this specification. ing.

  Further, by introducing the back wind W into the transfer duct 5, the suction force (negative pressure suction force) by the back wind W is applied to the upper surface of the teacup T facing the lower end opening (a transfer start portion 5 </ b> S described later) of the transfer duct 5. ) Acts, and the transfer object A located on the teacup T is sucked and removed by strengthening the suction force. Here, a range where the suction action by the back wind W reaches the upper surface of the teacup T is defined as a suction action area AR. In addition, since the attachment of the attachment 7 is premised on the site where the negative pressure suction by the back wind W starts, in particular, the portion where the negative pressure suction starts when the attachment 7 is attached is the suction action start part BS. Yes, in this embodiment, it is substantially the same part as a transfer start part 5S described later. The attachment 7 is attached in order to strengthen the suction force (suction action) by the back wind W by narrowing the suction action area AR (the suction action area AR that the back wind W exerts on the top surface of the teacup T). It is.

Hereinafter, the transfer duct 5 and the air duct 6 will be described in more detail.
As described above, the transfer duct 5 is configured to transfer the transfer object A located on the teacup T onto the back wind W and transfer it to the storage unit 4. Due to such a transfer mode, the transfer duct 5 is provided on the front plate 51 provided on the front side (front side) of the tea garden management device 1 and on the rear side of the tea garden management device 1, for example, as shown in FIG. The back plate 52 and the side plate 53 provided so as to connect them are formed in a hollow shape (wind tunnel shape), and the upper and lower ends of the duct are formed in an open state. Here, the lower opening where the transfer object A starts to be transferred in the transfer duct 5 is defined as a transfer start portion 5S. If the attachment 7 is not attached, the transfer start portion 5S is the same as the suction action start portion BS. Further, the upper opening where the transfer of the transfer object A ends is a transfer end portion 5E, and the transfer end portion 5E has, for example, a discharge port 54 facing the storage portion 4 as shown in FIG. Is formed.

  Here, at the lower end edge of the front plate 51, for example, as shown in FIGS. 2 and 3, a front adjustment plate 510 that is slidable in the vertical direction is provided. Specifically, as shown in the figure, for example, the front adjustment plate 510 is attached to the front plate 51 with wing screws 511 (here, six locations), and screw insertion formed on the front adjustment plate 510 is performed. The front adjustment plate 510 can be slid up and down by forming a common hole vertically long. Reference numeral 512 in the drawing is a long hole formed in the front adjustment plate 510.

In addition, the transfer start portion 5S in the transfer duct 5 is formed to have, for example, a slightly higher curved shape at the center and a length substantially the same as the width direction dimension of the teacup T, in accordance with the shape of the upper surface of the teacup T. The
On the other hand, as shown in FIG. 2, for example, the transfer end portion 5 </ b> E is appropriately curved so that the discharge port 54 faces the storage portion 4 in a side view state of the tea garden management device 1. Incidentally, FIG. 2 shows a case in which the transfer object A removed from the teacup T is finally collected in a storage bag, and a hook F for attaching the open end side of the storage bag to the discharge port 54. Is provided.

  Note that the transfer duct 5 does not necessarily have to be formed upright, and as described above, the transfer duct 5 can also be formed in a somewhat inclined shape on the rear side. In this case, the transfer object A is transferred to the transfer duct 5 ( It is difficult to spill from the transfer start portion 5S) to the front side and is smoothly blown up. However, when the transfer duct 5 is formed to be inclined rearward, the overall length of the tea plantation management device 1 (extended dimension to the rear) becomes longer, and the handling performance of the device is reduced. The angle is set in consideration of this.

Further, it is preferable that the transfer duct 5 does not change the width dimension, the cross-sectional area, etc. suddenly during the transfer from the transfer start part 5S to the discharge port 54 (transfer end part 5E). This is to reduce as much as possible the damage to the tea leaves associated with the transfer when the tea leaves are just after plucking. Further, as shown in FIGS. 1 and 3, for example, the transfer path is formed such that a branch portion 55 is formed in the middle of transfer and the transfer path is divided into two forks. Since this branch part 55 is a part that divides the transfer object A to be moved up and down into left and right parts, the inside of the transfer path has a smooth R shape, that is, a transfer path so that tea leaves that can be transferred hit the branch part 55 as much as possible. As for, the structure which comprises substantially U shape and distributes the transfer target object A right and left smoothly is preferable.
In addition, it is desirable that such a transfer duct 5 is at least partially nested or flexible and can move up and down together with the lifting bracket 21C.

  Furthermore, as shown in FIG. 3 as an example, the transfer duct 5 is provided with a transfer promotion plate 56 in an upward inclined state with respect to the back plate 52 of the transfer duct 5 immediately after the blowing portion 50. The upward inclination angle of the transfer promoting plate 56 is appropriately changed depending on the size and properties of the transfer object A, the air volume of the blower 27, and the like, and is set to an upward inclination angle of about 40 to 70 degrees. In addition, since the back wind W sent from the blowing part 50 is smoothly blown upward (toward the rear) along the transfer promotion plate 56 by this transfer promotion plate 56 (so-called Coanda effect), the transfer duct. 5 does not cause any disturbance in the transfer start section 5S and the like.

  Next, the air duct 6 will be described. As described above, the air duct 6 is a duct for sending the back wind W from the rear side of the transfer duct 5 into the duct 5 (for example, in the vicinity of the transfer start portion 5S), and is in close contact with the back side of the transfer duct 5 Is provided. In forming the transfer duct 5 and the air duct 6, the transfer duct 5 and the air duct 6 can be formed in completely separate duct shapes, and these can be stretched. It is also possible to use the plate 52 as the front surface of the air duct 6 (so-called common structure).

  In addition, the air duct 6 is formed in a hem-like shape in the rear view of the tea garden management device 1 so as to take in the pressure air from above and blow out as an upward flow from the blowing portion 50 of the transfer duct 5. Here, the intake port for the pressurized air is used as the inlet 61, and the relay duct 28 connected from the blower 27 is connected to the inlet 61 (see FIG. 2A).

  Next, the attachment 7 will be described. The attachment 7 is for strengthening the suction force that the back wind W exerts on the top surface of the teacup T. In this embodiment, for example, as shown in FIG. 5, the transfer start portion 5S and the top surface of the teacup T are separated. The attachment 7 is provided so as to partially shorten the distance. Thereby, the suction action area AR on the front side (the suction action area AR that the back wind W exerts on the top surface of the teacup T) is narrowed, and the suction force exerted on the top surface of the teacup T is strengthened more than when not mounted. In the present embodiment, the attachment 7 is provided so as to shorten the separation distance on the front side, but the attachment 7 may be provided so as to shorten the separation distance as a whole. Further, in this specification, the portion where the suction action of the back wind W starts with the attachment 7 as described above is particularly referred to as “suction action start portion BS”, and the substantial transfer start portion 5S of the transfer duct 5 is provided. It is distinguished from.

Hereinafter, the specific configuration of the attachment 7 will be described in more detail. As shown in FIGS. 3 and 4 as an example, the attachment 7 of the present embodiment includes a plate-like restricting body 71 as a main member, which is a member corresponding to the attachment main body. The restricting body 71 is attached to the front adjustment plate 510 of the transfer duct 5 in a suspended or overlapping manner.
Further, as shown in FIG. 3, the plate-shaped restricting body 71 in the present embodiment is a horizontally long plate having substantially the same width as that of the teacup T, and the lower end edge of the teacup T is viewed from the front. The shape is substantially the same as the front view shape. Incidentally, the regulation body 71 can be formed of a polycarbonate plate material having a thickness of about 12 mm, for example, but the thickness dimension, the material, the shape, or the like can be appropriately changed.

Next, an example of how to attach the regulating body 71 (fixed to the front adjustment plate 510) will be described. As described above, the upper end portion of the restricting body 71 is attached to the front adjustment plate 510 of the transfer duct 5. More specifically, for example, as shown in FIG. The adjustment plate 510 is attached so as to protrude below the lower end edge.
In this attachment, as shown in FIG. 3, an angle material H1 having an L-shaped cross section is previously attached to the front adjustment plate 510 side in a straight line so as to be substantially along the width direction of the teacup T. Here, as an example, six places are screwed.
Further, the restricting body 71 is also provided with angle members H2 having an L-shaped cross section attached to the upper edge in advance (for example, six locations, screwed).
In actual mounting, the L-shape of the angle member H2 fixed to the restricting body 71 on the piece of the L-shaped cross section of the angle member H1 fixed to the front adjustment plate 510 (the portion projecting forward). By placing a piece of the cross section (a portion projecting to the rear side) and fastening the angle members H1 and H2 with screws H3 (two places as an example), the regulating body 71 (attachment 7) is attached to the front adjustment plate 510. It is to be fixed to.

In this way, in this embodiment, the pieces of the angle members H1 and H2 are overlapped with each other and the restricting body 71 is attached to the front adjustment plate 510 in a suspended manner. The front adjustment plate 510 is attached substantially in parallel with a certain gap. However, the attachment of the restricting body 71 is not necessarily limited to such a form. For example, the restricting body 71 is directly provided on the front adjustment plate 510 in an overlapping state without using the angle members H1 and H2. Is also possible (see FIG. 7B).
Note that the lowermost position of the restricting body 71 can be changed by raising and lowering the front adjustment plate 510 (height adjustment can be set), and the distance (separation distance) from the top surface of the teacup T can be adjusted. It can be done.
Incidentally, the attachment 7 is attached when sucking / removing the transfer object A such as fallen leaves and the like located on the teacup T, or when cutting the tea branches and leaves while maintaining the tea tree posture. When it is desired to perform the plucking work as usual, it is not always necessary to attach it.

Here, FIG. 5A shows the suction action area AR that the back wind W exerts on the top surface of the teacup T when the attachment 7 is not attached. On the other hand, in FIG. 5B, when the attachment 7 shown in FIG. 3 is attached, the suction action area AR becomes narrower than when the attachment 7 shown in FIG. It shows how it works. That is, in FIG.5 (b), since the space | interval (separation distance in the suction action start part BS) between the lower end edge of the attachment 7 (regulation body 71) provided in the front side of the tea garden management apparatus 1 and the teacup T becomes short. The suction side action area AR on the front side is narrowed. Then, the suction force is strengthened as much as the suction action area AR is narrowed, and even if the fallen leaves (transfer object A) easily get entangled with tea trees or the like, the tea bowl T is surely attached. It can be sucked and removed from.
Incidentally, the suction action by the back wind W extends to the upper surface of the teacup T on the rear side of the tea garden management device 1, but the rear side does not change the separation distance from the teacup T, so that the suction action area AR is also used. Therefore, this situation is not shown in FIG.

  Note that the attachment 7 is normally set so that the lower end edge of the regulating body 71 is positioned below the blowing portion 50 as shown in FIG. For example, as shown in FIG. 6, for example, as shown in FIG. 6, there may be a setting in which the lower end edge of the regulating body 71 is positioned above the blowing portion 50, which depends on various assumed transfer objects A and the like. This is one of the possible situations. FIG. 6 can be said to be a case where the separation distance between the suction action starting portion BS and the upper surface of the teacup T is shortened on the rear side and longer on the front side.

  Next, the accommodating part 4 is demonstrated. The accommodating part 4 is a part which finally accommodates (recovers) the transfer object A such as fallen leaves that have been transported by the transfer device 3, and FIG. 1 shows a container-type large accommodating part 4. . Of course, the storage unit 4 is not limited to such a container type, but may be of a type in which a storage bag is suspended as shown in FIG. In the case of a bag, the opening of the storage bag is attached so as to face the discharge port 54 of the transfer duct 5, and the transfer object A is packed into the storage bag in a natural fall state. Further, in the case of the bag type, a foldable opening / closing type mounting table is provided on both sides of the tea garden management device 1, and when the storage bag is filled with the transfer object A during the work, The mounting table is opened in a wing shape from the folded state, and the accommodation bag is placed thereon.

Further, as described above, the attachment 7 may be attached to an existing tea cutting device, and in this case, the tea cutting device (tea garden management device 1) includes the cutting blade C. Incidentally, the position where the cutting blade C is provided is generally directly below the blowing portion 50 as shown in FIGS.
In addition, the tea cutting device (tea garden management device 1) to which the attachment 7 is attached may perform the plucking operation, or the aspiration and removal of the fallen leaves (transfer object A) may be performed. Thus, the cutting blade C does not necessarily have to be driven when sucking and removing the fallen leaves (transfer object A).

[Other Examples]
The present invention has the above-described embodiment as one basic technical idea, but the following modifications can be considered. That is, in the above-described embodiment, the configuration as a general-purpose machine in which the attachment 7 is attached to the existing tea garden management device 1 has been mainly described. However, as the transfer object A, various things such as fallen leaves, ash fall, insects, vinyl and other foreign matter (dust) are assumed, and when a unique setting corresponding to each of these is preferable, the tea garden management device 1 can also be used as a dedicated machine, that is, a dedicated ash removal machine, a foreign object removal dedicated machine, or the like.

Further, in the basic embodiment described above, as shown in FIG. 5, the separation distance (interval) from the upper surface of the teacup T of the transfer start portion 5S (suction action start portion BS) is partially set by attaching the attachment 7. Alternatively, it is contracted as a whole, thereby narrowing the suction action area AR on the top surface of the teacup T, thereby enhancing the suction force. However, in order to strengthen the suction force that the back wind W exerts on the top surface of the teacup T, not only the separation distance is shortened but also the opening of the transfer start portion 5S (suction action start portion BS) as shown in FIG. It is also possible to increase the suction force by reducing (decreasing) the area.
Here, FIG. 7 (a) shows the transfer device 3 (transfer start part 5S) not equipped with the attachment 7, whereas FIG. 7 (b) is bent and formed in a cross-section “<” shape. The attached attachment 7 (regulator 71) is directly attached to the front adjustment plate 510 so that the opening area of the suction action starting portion BS is narrowed (squeezed) and the suction force is strengthened.
In addition, this FIG.7 (b) can also be said to be the modification of the attachment 7 which does not use the control body 71 as a flat plate-shaped member.

  Moreover, in the basic example mentioned above, although the regulation body 71 of the attachment 7 was mainly plate-shaped, it is not necessarily limited to this. In other words, the mode of transferring the picked tea leaves or the like is not limited to those depending only on the back wind W, but for example, as shown in FIG. (See, for example, Japanese Patent Application Laid-Open No. 2012-75416 “Transferring apparatus for tea leaves and teabrushing apparatus having the same” by the present applicant). This is a transfer mode in which the tea leaves immediately after cutting with the cutting blade C are first fed to the back side of the transfer duct 5 by the rotating body R and then placed on the back wind W, and the tea leaves are reliably sent into the transfer duct 5. Is intended. Incidentally, such a transfer mode using the rotating body R together is also included in the slit-jet type transfer mode because the rear wind W is used. In addition, there are some that the rotating body R itself takes on the action of the cutting blade C, but such a thing is also included in the slit-jet type transfer mode because it eventually carries the tea leaves on the back wind W. .

  And when attaching the attachment 7 to the transfer apparatus 3 (tea garden management apparatus 1) which adopts the slit-jet type transfer mode combined with such a rotating body R, as shown in FIG. The attachment 7 is preferably formed in a three-dimensional shape (case shape) so as to cover the rotating body R. In this case, it is preferable that the inner surface on the front side of the attachment 7 is formed so as to be substantially along a cylindrical orbit (circular orbit in a cross-sectional view) drawn by the rotator R, which efficiently uses the back wind W discharged from the blowing portion 50. This is because it is sent to the inner side of the transfer duct 5.

In the basic embodiment described above, the suction action start part BS (transfer start part 5S) and the blowing part 50 are shown close to each other, but depending on the properties of the transfer object A, for example, As shown in FIG. 8 (b), it may be preferable to provide a certain distance from the suction action starting portion BS to the blowing portion 50. In such a case, the attachment 7 (regulator 71) itself is formed so as to protrude forward, and the suction action start portion BS by the back wind W is formed at the tip portion (at the tip of the attachment 7). Is. Of course, also in such a case, the attachment 7 is formed in three dimensions.
In consideration of such a form, in order to reinforce the suction force exerted by the back wind W on the upper surface of the teacup T, the attachment part (regulator 71) is attached to the blowing part 50 (transfer) from the suction action starting part BS. It can also be said that it is important that the section up to the start part 5S) is almost closed in a tunnel shape. Conversely, even if the attachment 7 (regulator 71) is mounted, if there is a gap communicating with the outside in the section from the suction action start part BS to the blowing part 50 (transfer start part 5S), the suction action start part Even if the separation distance is shortened with BS or the opening area is reduced, it is considered that the enhancement of the suction force cannot be expected so much.
