JP 2006-50963 A

  What is shown in Patent Document 1 is blowing up from the position immediately after the clipper type cutting blade, and since the blowing port covers the entire width of the clipper type cutting blade, the width of the transport duct is the same as that of the cutting blade. Need to be widened. If it is wide, the rear side cannot be seen and the work becomes difficult. When the width is narrowed, the air volume in the transport duct is reduced, and the transport amount of tea leaves is reduced. Therefore, in order to increase an air volume, there existed a fault which had to enlarge a fan.

  In addition, Japanese Patent Application No. 2005-213131 filed by the applicant has a configuration in which pressure air is blown from a position behind a cutting blade unit case to which a clipper type cutting blade is attached. In this configuration, the picked-up tea leaves are sucked up and blown up, and the venturi effect also acts so that the tea leaves can be transported well to the transport duct. However, the existence value of the rotating body is not necessarily clear.

  In patent document 1, while it was the structure which is blowing up from the position immediately after a hair clipper type cutting blade, since it covered the full width of this hair clipper type cutting blade, there existed a fault that the air volume used for transport of a tea leaf decreased. In particular, the tea leaves have a serious drawback that they are stacked (clogged and stuck) at the entrance of the transport duct or the inclined surfaces on both sides and the transport path inside the transport duct. In addition, in Japanese Patent Application No. 2005-213131, when the buds of tea leaves to be plucked are long, or in the case of a weak tree with a young tree, the buds of tea leaves are cut too deeply due to the presence of a rotating blade, before hitting a fixed cutting blade, It was pushed down and left on the surface of the tea tree without hitting the cutting blade, and the cuts were mottled.

  For this reason, we will develop a traveling type tea leaf picking machine that prevents the size of the traveling type tea leaf picking machine body from becoming large and complicates the device, and efficiently transports the picked tea leaves from the picking device to the tea leaf storage device. There was a problem. Therefore, the applicant has applied for Japanese Patent Application No. 2005-213131 in order to solve the problem. Although most of the problems can be solved by the present invention, there is a problem in that the tea leaves are transported from the plucking device to the tea leaf storage device with high efficiency. That is, in particular, it is a problem to enable the sucked tea leaves to be sucked more efficiently and fed into the transport duct with the pressure air without scattering outside. Furthermore, it is also a problem to prevent tea leaves from being stacked (sticking) on the entrance of the transport duct or on the inclined surfaces on both sides.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a traveling tea leaf picking machine, and is a crawler traveling device 1 provided with an appropriate interval (teacup T). , 2 are fixed to a machine base on which an operator or the like rides through the gate form frames 3 and 4 before and after this to form a housing and a traveling part. The distance between the traveling devices 1 and 2 can be adjusted as appropriate, and is provided so as to correspond to the width of the teacup T. A plucking device A that can be appropriately moved up and down to the height of the teacup is provided below the center of the machine base.

  The plucking device A is composed of a clipper-type cutting blade 5 that plucks tea leaves by a shearing action and a cutting blade unit case 6, and has a flat arch shape when viewed from the front along the upper side shape of the teacup T. There is no. Specifically, as shown in FIGS. 2 and 3, a clipper-type cutting blade 5 in which the upper and lower blades move alternately is formed in an arch shape below the cutting blade unit case 6 (see FIGS. 2 and 3). It is provided so that it can be driven by a drive unit (not shown).

Further, the cutting blade unit case 6 has a width corresponding to the length of the hair clipper type cutting blade 5, and side plates 6 a, 6 a positioned on the front side of the position of the hair clipper type cutting blade 5 are formed on both sides. The back side is provided with a back plate 6b that rises in an arc shape immediately after the clipper-type cutting blade 5 and has a substantially vertical surface thereafter. Further, substantially trapezoidal duct introduction portions 6c and 6c are provided above the side plates 6a and 6a and the back plate 6b, and the upper portion is divided in two and is narrowed.

  A front surface of the cutting blade unit case 6 is opened, and a pre-adjustment cover 6d is configured to be vertically adjustable via a long hole on the upper surface thereof. The pre-adjustment cover 6d is provided on the left and right sides so as to correspond to the duct introduction portions 6c and 6c. In the case of mibu buds (such as No. 1 tea when the buds of tea leaves are young), the buds have a high moisture content and are short and the length of the buds is short. In addition, in the case of buds (2nd tea, 3rd tea, etc. when the buds of tea leaves are not young), the handle is large and long, does not contain moisture, and is easy to fly, so the position of the cover 6d before adjustment is raised. Reduce the suction pressure to increase the air volume and suck it for transportation.

  Further, on the upper side of the two duct introducing portions 6c, 6c of the cutting blade unit case 6, there are provided transport duct connection cases 7, 7 branched left and right. The upper ends of the transport duct connection cases 7 and 7 are connected to the lower ends of the transport ducts 8 and 8 so as to be vertically adjustable. As a result, the tea leaves picked up by the clipper-type cutting blade 5 can be transported to the upper tea leaf storage device B through the cutting blade unit case 6, the transport duct connection cases 7, 7 and the transport ducts 8, 8. It is configured. The transport duct 8 is formed so that the opening area of the inlet (lower end) and the outlet (upper side) is equal, and is substantially equal to the upper end cross section of the transport duct connection case 7.

  Reference numeral 9 denotes a down duct, and the lower end of the down duct 9 is branched to the left and right sides of the back plate 6b of the cutting blade unit case 6 so as to correspond to the duct introducing portions 6c and 6c. Connected to the left and right. Specifically, as shown in FIG. 3, the lower end of the down-flow duct 9 is formed as a semicircular arc-shaped portion 9a when viewed from the side, and a flat elongated main blower inclined upward from the semicircular arc-shaped portion 9a. The raising port 9 b is connected to the vertical surface of the back plate 6 b of the cutting blade unit case 6. Further, the inclined upward angle is preferably about 40 degrees to about 90 degrees. Further, it is preferably an acute angle of about 45 degrees or more and about 90 degrees. In the example, the tilt upward angle is about 60 degrees.

    As a result, the air is blown downward from the blower duct 9 through the flexible blower duct 10 from the blower 11 provided on the machine base frame 4, and the direction is changed by the semicircular arc-shaped portion 9a. It blows out from the main blow-up port 9b. With such a configuration, the picked tea leaves are blown in the direction of the main blow-up port 9b due to the suction action by the air blown from the main blow-up port 9b.

    The cross-sectional area of the transport duct is substantially the same from the inlet to the outlet. The almost identical concept includes a range of about 10% variation. In particular, the width of the main blow-up port 9b of the down-flow duct 9 and the width of the lower end of the transport duct 8 are formed to be equal. As a result, the picked tea leaves can be prevented from being deposited and clogged in the duct introducing portion 6c of the cutting blade unit case 6. Further, although the transport duct connection case 7 has been described as having a separate structure from the cutting blade unit case 6, it may be configured integrally with the cutting blade unit case 6. In this case, the upper end of the cutting blade unit case 6 is attached to the lower end of the transport duct 8 so as to be vertically adjustable. The blower 11 blows a predetermined amount of air to the blow-down duct 9 at an appropriate wind pressure. Specifically, the two blowers 11 and 11 are connected to the blow-down duct 9 via the blow ducts 10 and 10. It is connected to the upper ends of the down ducts 9 and 9.

  Next, the operation of the traveling tea leaf plucking machine and the operation of tea leaf transportation will be described. First, the traveling devices 1 and 1 are caused to travel in the grooves a and a between the teacups T and T, and the height position of the plucking device A is adjusted during traveling. That is, the height position of the plucking device A is moved up and down by a hydraulic drive device (not shown), and the position of the clipper-type cutting blade 5 of the plucking device A is well plucked from the tea leaves (tea leaf buds) on the surface of the teacup T. This is to make it possible. Simultaneously with traveling, the plucking device A and the blowers 11 and 11 are driven.

  Then, a pressure wind is generated and blown down through the blower ducts 10, 10 to blow the pressure wind to the main blow-up port 9 b of the duct 9. As a result, a negative pressure is generated in the cutting blade unit case 6. At the same time, the plucking device A is driven. That is, the tea leaves on the teacup T are cut into a predetermined length by the action of the clipper-type cutting blade 5. The cut tea leaves rose while sliding on the arc-shaped surface of the back plate 6b of the cutting blade unit case 6, and were cut by the venturi action by the pressure air blown upward from the lower side of the main blowing port 9b. The tea leaves are blown upward and are transported from the transport duct 8 to the tea leaf storage device B.

  In the first embodiment, a transport duct 8 having a width narrower than the left and right width of the clipper-type cutting blade 5 is raised right above the clipper-type cutting blade 5 that is horizontally long in the left-right direction. The cutting blade unit case 6 is provided so as to surround the hair clipper-type cutting blade 5 and the front side of the hair clipper-type cutting blade 5 is tea buds. The left and right side walls of the lower cutting blade unit case 6 are adjusted to the left and right widths of the hair clipper type cutting blades 5 and the left and right widths are tapered in the upward direction. It connects with the entrance of the lower end of the transport duct 8 provided in the upper part of the blade 5, and the width of the transport duct 8 is approximately equal to the entrance of the transport duct 8 on the rear plate 6b on the rear part of the cutting blade unit case 6. Same width pressure Air outlet 9b of the (high-speed air stream) is provided.

Can be blown up. The plurality of auxiliary blowing small holes 14b, 14b,... Are configured to have substantially the same width as the hair clipper type cutting blade 5. Moreover, although it is the branch type auxiliary duct 14 in FIG. 6, there may be another independent small fan without branching.

  In terms of air volume, it is about 70 to 80% from the main air outlet 9b of the down-flow duct 9, and from a large number of small auxiliary air holes 14b, 14b,... It is comprised so that it may become about 30-20%. As a result, immediately after the tea leaves are picked up, the blowing can be performed over the entire width of the clipper-type cutting blade 5, and the overall blowing can be performed. For this reason, the suction from the main blow-up port 9b of the down-flow duct 9 can be performed smoothly. In particular, tea leaves plucked in rainy weather tend to stick to the back of the cutting blade unit case 6, but the blowing wind pressure is applied uniformly with a small air volume at the numerous auxiliary blowing small holes 14b, 14b,... It is sucked upward and transported well.

  Next, a third embodiment will be described with reference to FIGS. Explanations and drawings of the same configuration are also omitted. A second duct 15 is provided from the back surface of the down duct 9 through a branch port 15a. The front side of the second duct 15 is formed as an auxiliary blowing port 15 b and is configured to have the same width as the clipper type cutting blade 5 immediately after the clipper type cutting blade 5. In FIG. 8, the second duct 15 is a branched type, but there may be another independent small fan without branching. The amount of air is about 70 to 80% from the main air outlet 9b of the down duct 9 and about 30 to 20% from the auxiliary air outlet 15b of the branched or independent second duct 15. It is configured as follows. As a result, immediately after the tea leaves are picked up, the blowing can be performed over the entire width of the clipper-type cutting blade 5, and the overall blowing can be performed. For this reason, the suction from the main blow-up port 9b of the down-flow duct 9 can be performed smoothly.

  Further, as shown in FIGS. 10A and 10B, the scraper plate 17 is configured to be swingable to the left and right sides with respect to the central branch point at the center position in the width direction of the cutting blade unit case 6.
