[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spray control device for a compost spreader, and in particular, a compost spreader for controlling a spray width and a spray height of compost sprayed rearward from a spray port formed at a rear end of a packing box. The present invention relates to a spray control device.

[0002]

[Prior art]

 As an example of a conventional compost spreader, as shown in FIG. 9, a tractor (not shown) draws a tractor (not shown), a loading platform 4, a loading box 3 for loading the compost M, and a loading platform 4. Freely supported traveling wheels 5, floor conveyor 12 for post-delivery of compost M, and packing box Two vertical axis beaters 70 are provided at the opening at the rear end, and further pivoted on both sides of beater 70. A restriction plate 72 that can be freely fixed at an arbitrary opening angle is provided.

The compost M sent by the floor conveyor 12 is scraped out by the wings 71 of the beater 70, and is splashed and scattered in the rotation direction. The spattered compost M is regulated by the regulation plate 72 in the width direction, but is scattered far away from the rear of the machine body.

In addition, Japanese Utility Model Application Laid-Open No. 57-8 9407 is disclosed for both side spraying suitable for compost spraying work in orchards.

[0005]

[Problems to be solved by the device]

 When the compost M is scattered far behind the machine, it is difficult to determine the position of the machine at the beginning of spraying when spraying inside the house or on the shore. If they are to be made uniform, they will adhere to the house or the house pillars 75 and become dirty or corrode. Also, in the case of fields, paddy fields, etc., compost may be scattered on the road or even to the adjacent fields.

[0006] On the other hand, if the scattered compost starts to spread at a position that does not reach the house or the shore, the compost is spread in a fan shape, resulting in uneven density in the spray density or leaving unsprayed parts. .

[0007] In Japanese Utility Model Laid-Open No. 57-89407, since a compost guide plate having a roof shape is erected on a pedestal so as to cover the central portion of the frame body at a constant interval with a beater, a normal compost is formed. If you try to spread it, you have to remove the compost guide plate, which is troublesome.

Further, in Japanese Utility Model Laid-Open No. 58-146416 and Japanese Utility Model Laid-Open No. 59-64606, since the scattering compost is simply applied to the regulation plate to limit the spraying width, the regulation plate There is a problem that the compost that adheres to the shavings drops off, and only that part is spread in a streak pattern.

The present invention was created to effectively solve the above problems.

It is an object of the present invention to provide a spray regulation device for a compost spreader, which can prevent the compost from adhering to a house or a house pillar and can evenly spread the compost.

[0011]

[Means for Solving the Problems]

 The present invention relates to a compost spreader for spreading compost backward by a pair of disc type beaters that rotate inwardly and outwardly from a spraying port formed at the rear end of a cargo box towed by a tractor. A pair of inner side restrictions attached to the left and right edges of the spray port so as to be detachable and rotatable in the horizontal direction so that the angle can be adjusted, and the tip end extends rearward in the spray direction along the track of the beater. The plate is attached to the outside of the inner regulating plate coaxially with the inner regulating plate in a freely detachable and horizontally rotatable manner so that the angle can be adjusted, and the tip is behind the tip of the inner regulating plate in the spray direction. It is composed of a pair of outer regulation plates that regulate the spread width of the compost that is extended to the rear and is sprayed rearward by the beater.

Further, an upper regulating plate is attached to the upper edge portion of the spray port so as to be detachable and rotatable in the vertical direction so that the rotation angle can be adjusted.

Further, the inner side regulation plate, the outer side regulation plate and the upper side regulation plate are detachably and angularly attached via a chrysanthemum seat.

[0014]

[Action]

 In this way, the pair of outer regulating plates attached to the left and right edges of the spraying port extend rearward in the spraying direction to regulate the spraying width of the compost. On the other hand, the inner regulation plate cuts off the compost that is about to fly out right next to the beater and guides it toward the beater side, and also prevents the compost from adhering to the outer regulation plate, reducing the amount of compost fluff and reducing streaks. It is possible to alleviate the thickening.

Further, the upper regulating plate attached to the upper edge of the spraying port adjusts the spraying height and the spraying distance of the manure by rotating in the vertical direction, and at the same time the inner regulating plate and the outer regulating plate are made uniform. It makes it possible to obtain a dispersion of density.

Furthermore, since the inner regulating plate, the outer regulating plate and the upper regulating plate are attached via the chrysanthemum, the angle can be easily adjusted.

If the stopper 4a is not provided, the pair of gears 42 come close to each other and can rotate immediately before contacting, that is, up to a little over 90 degrees each on the left and right.

As shown in FIGS. 1 and 2, the spraying device 6 is arranged in the opening at the rear end of the luggage box 3, and its structure is that it is installed on both side plates 18 and both side plates 18 and has a lower spray port. A top plate 17 that covers the rear and the upper part so as to form S, two disc-type beaters 15 arranged at the lower rear end of the floor conveyor 12, and these beaters 15 from the inside in the opposite directions. Power transmission devices (not shown) that rotate outward in the directions of arrows A and A ′, respectively, are installed inside, and the lower casing 16 provided with a front spray prevention plate 48 and both side plates located above the disc type beater 15 are installed. It is composed of a horizontal shaft type beater 14 which is laterally mounted between 18 and pivotally supported by both side plates 18 so as to rotate in the direction of arrow B.

That is, the compost M sent to the opening at the rear end of the luggage box 3 by the floor conveyor 12 is scraped out by the upper horizontal shaft type beater 14, crushed, and dropped onto the beater 15. The compost M is widely spread in the rotation direction by the blades 20 radially fixed to the disc 19 of the disk type beater 15.

Particularly, in the present invention, in the compost spraying work in a house or the like, the rotating directions of the left and right disc-type beaters 15 are controlled from the inside in order to regulate the scattered compost and obtain the spray in a uniform piled state. It is rotated outward (arrows A, A ') and is supported by U-shaped brackets 49 that are fixed to the side plates 18 that form the left and right edges of the spout S by being positioned on both sides, behind the center. This means that the pin 26 is provided in a protruding manner, and two types of restriction plates 22, 21 of long and short are attached to the pin 26 so as to be rotatable and detachable.

That is, as shown in FIG. 5, the restriction plates 21 and 22 are plate-shaped bodies having one end formed in a U-shape, and washers 23 and 28 are provided at the lower ends of the U-shaped portions and the upper ends are provided at the upper ends. Kikuza 24 and 29 are provided.

For attachment, the regulation plates 21 and 22 are overlapped, the holes of the washers 23 and 28 at the lower end are fitted into the support pins 26, and the chrysanthemums 24 and 29 at the upper end and the chrysanthemum provided on the bracket 49 fixed to the side plate 18 are attached. The seats 27 can be engaged with each other, and the restriction plates 21 and 22 can be fixed at arbitrary angles with bolts 25. In the embodiment, it is desirable that the inner regulating plate 21 is fixed near the blade 20 of the disk-type beater 15 and along the rotation path of the tip end thereof, and the outer regulating plate 22 is an angle at which the required spreading width can be obtained. You can fix it with. That is, the base ends of the restriction plates 21 and 22 are supported rotatably in the horizontal direction with the axis connecting the bolts 25 and the pins 26 as a common rotation axis, and the fixed side chrysanthemum 27 and the inner side. The chrysanthemum seat 24 of the regulation plate 21 is engaged with the inner regulation plate 21 so that the inner regulation plate 21 can be horizontally rotated at an arbitrary angle by one pitch. It engages with 29 of the chrysanthemum 22 to allow the outer regulating plate 22 to be horizontally rotated by one pitch at an arbitrary rotation angle independently of the rotation of the inner regulating plate 21.

FIG. 6 shows a schematic sprayed state of the compost M when the regulation plates 21 and 22 are acted on the right side, and the regulation plates 21 and 22 are folded on the left side and the regulation plates 21 and 22 are not acted on. Shows the sprayed state. The compost M sent to the rear of the packing box 3 by the floor conveyor 12 is scraped out by the horizontal shaft type beater 14, crushed, falls on the disk type beater 15, and is splashed in the rotation direction of the blades 20. To go.

The dashed-dotted line in FIG. 6 is a contour line of the spray when the flight distance after the compost hits the blade 20 is the same. When the regulation plates 21 and 22 are not actuated (on the left side), there is compost M scattered and scattered in the lateral direction of the rear part of the machine body, which is a small amount but forms the maximum spreading width. In addition, if the covering distance during traveling is short, the spray state X becomes extremely thin. When sprayed in a house, the compost scattered and scattered in the lateral direction adheres to the pillars or stains the house.

The outer regulation plate 22 blocks the compost M that is about to scatter and scatter in the lateral direction and drops the compost M on the inner side thereof to concentrate the compost M and reduce a portion which becomes extremely thin. Further, the spraying range of the compost M is expanded by changing the meshing position of the chrysanthemum 29 on the upper end of the regulation plate 22 and increasing the opening angle.

On the other hand, the inner regulating plate 21 is fixed near the blades 20 of the disk-type beater 15 along the rotation locus thereof in the embodiment, and blocks the compost M that is about to jump out right next to the lower casing. Drop it on top of 16, and swirl it around with the blades 20 to spray it from the center of the spout S to concentrate the compost on the rear side of the machine. At this time, since the tip of the inner side regulating plate 21 is fixed near the blade 20 of the beater, the compost M does not continue to adhere, and the compost M does not drop from this part. This cuts off the compost M to be attached from the mounting portion of the outer regulation plate 22 to the central portion, and reduces the amount of the compost M that adheres to the regulation plate 22 and drops off and reduces streaks in a streak pattern. .

Further, as shown in FIGS. 1, 2 and 5, an upper regulating plate 60 narrower than the width of the spray port S is provided at the rear lower end of the top plate 17 that defines the upper edge of the spray port S. ing. In the practical example, the width is about 2/3 of the width of the spout S. As shown in FIG. 5, the regulating plate 60 has a box shape, and is provided on an upper end extension portion, chrysanthemum seats 61 provided on both sides, and a bracket 67 fixed to a lower rear end of the top plate 17. It is fixed with bolts 63 so that it can be engaged with the chrysanthemum seat 62 and adjusted to an arbitrary opening angle.

Further, locking plates 69 having holes 66 are provided on both sides of the rear end of the lower casing 16 in order to loosen the bolts 63 and lower the regulation plate 60 to bring it into a "closed" state. Is fixed by inserting the pin 64 provided on the upper regulating plate 60 into the hole 66 of the locking plate 69. The pin 64 is urged by the spring 65 via the pin 68 toward the hole 66.

Therefore, various actions can be obtained by combining with the opening angles of the regulation plates 60, 21, 22 installed near the spray port S. That is, when the regulation plate 60 is fixed in a half-opened state by inclining downward from the horizontal and the regulation plates 21 and 22 are folded (opened) or removed, the compost from the central portion of the spray port S that scatters far away from the rear of the machine body. Is blocked by the regulation plate 60, collides, and falls near the rear of the aircraft. In addition, since the regulation plates 21 and 22 are not used, a wide spraying state is obtained.

Further, as shown in FIG. 7, the upper regulation plate 60 is fixed in a half-open state by inclining downward from the horizontal, and the inner regulation plate 21 is arranged near the blades 20 of the disk-type beater 15 along its rotation track. When the outer regulation plate 22 is fixed to the outside and is parallel to the traveling direction of the machine body, in addition to the action of the upper regulation plate 60, the outer regulation plate 22 blocks the compost M that tends to scatter laterally and It is possible to drop and concentrate the compost M to obtain a spraying state with a narrow spreading width and uniform density.

Further, when the upper regulation plate 60 is fixed in the “closed” state and the regulation plates 21 and 22 are folded (opened) or removed, the compost M spreads on both sides as shown in FIG. It will be sprayed laterally only from the mouth S ', and will not be sprayed to the rear part of the machine body. This is suitable when compost is required only at the root of the fruit tree, such as compost application in orchards.
