[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray control device for a compost spreader, and more particularly, to a spread width and a spread height of a compost sprayed rearward from a spray port formed at a rear end of a packing box. And a spray control device for a compost spreader.

[0002]

2. Description of the Related Art As an example of a conventional compost disperser, as shown in FIG. 9, a tractor (not shown) pulls a traction device (not shown), a loading bed 4, and a loading box 3 for loading compost M. A running wheel 5 rotatably supported by the loading platform 4, a floor conveyor 12 for feeding the compost M, and two vertical beaters 70 are provided at the opening at the rear end of the packing box. The part is provided with a regulating plate 72 which is rotatable and can be fixed at an arbitrary opening angle.

The compost M sent back by the floor conveyor 12 is scraped out by the wings 71 of the beater 70, and is splashed and sprayed in the rotation direction. The compost M that has been splashed is regulated by the regulation plate 72 in the width direction,
It scatters far into the rear of the aircraft.

[0004] Japanese Utility Model Laid-Open No. 57-89407 discloses a double-side application suitable for compost application work in an orchard or the like.

[0005]

[Problem to be solved by the invention] Since the compost M scatters far behind the aircraft, it is difficult to determine the position of the aircraft at the beginning of spraying in the house or on the shore,
As shown in FIG. 9, if an attempt is made to make the spraying amount uniform up to the shore, it adheres to the house or the house support 75 and becomes dirty or corroded. In the case of a field, a paddy field, etc., compost is scattered on a road or an adjacent field.

[0006] On the other hand, when the flying compost starts to scatter at a position where it does not reach the house or the shore, the compost is scattered in a fan shape, resulting in uneven density of the scattered density or an unscattered portion remains.

[0007] In Japanese Utility Model Laid-Open No. 57-89407, since a roof-like compost guide plate is set up on a receiving stand so as to cover a central portion of a frame body at a constant interval with a beater, a normal compost guide is provided. If you want to spray, you have to remove the compost guide plate, which is troublesome.

In Japanese Utility Model Application Laid-Open No. 58-146416 and Japanese Utility Model Application Laid-Open No. 59-64606, since the compost which is scattered is merely applied to the control plate to restrict the spread width, the spread width is limited. There is a problem that the adhering compost falls down and the portion is streaked in a thick line.

The present invention has been made to effectively solve the above problems.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for controlling the spread of a compost spreader which can prevent the compost from adhering to a house or a house column and can evenly spread the compost.

[0011]

SUMMARY OF THE INVENTION According to the present invention, compost is rearwardly provided by a pair of disc-type beaters rotating from inside to outside in opposite directions from a spray port formed at a rear end of a load box pulled by a tractor. In the compost sprayer to be sprayed, the sprayer is detachably attached to the left and right edges of the spraying port so as to be rotatable in the horizontal direction so as to be adjustable in angle, and the tip extends rearward in the spraying direction along the rotation locus of the beater. A pair of inner regulating plates to be protruded, and the inner regulating plate is attached to the outside of the inner regulating plate so as to be coaxial with the inner regulating plate so as to be detachable and horizontally rotatable so that the angle can be adjusted. And a pair of outer regulating plates that extend rearward in the spraying direction and regulate the spread width of the compost sprayed rearward by the beater.

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

Further, the inner regulating plate, the outer regulating plate, and the upper regulating plate are attached via a chrysanthemum seat so as to be detachable and adjustable in angle.

[0014]

The pair of outer regulating plates attached to the left and right edges of the spray opening extend rearward in the spraying direction to regulate the spread width of the compost. On the other hand, the inner regulating plate blocks compost that is about to jump out to the side by the beater, guides it to the beater side, prevents the compost from adhering to the outer regulating plate, and reduces the amount of compost bobbing to form a streak. It is possible to mitigate plumping.

The upper regulating plate attached to the upper edge of the spray opening adjusts the height and distance of the spread of the compost by turning up and down, and the uniform regulating density together with the inner regulating plate and the outer regulating plate. It is possible to obtain a spraying state.

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

FIG. 6 is a schematic diagram showing the state of application of the compost M when the regulating plates 21 and 22 act on the right side, and the regulating plate 2 on the left side.
FIG. 3 shows a spraying state when the control plates 21 and 22 are folded and the control plates 21 and 22 are not operated. The compost M sent to the rear of the packing box 3 by the floor conveyor 12 is scraped and crushed by the horizontal axis type beater 14, falls on the disk type beater 15, and is splashed in the rotation direction of the blade 20. To go.

The dashed line in FIG. 6 indicates that the compost is
Is the outline of the scatter when the flight distance after hitting is the same. When the control plates 21 and 22 are not operated,
On the left side, there is compost M scattered and scattered in the lateral direction at the rear of the fuselage, which forms a small amount but forms the maximum spray width. In addition, the dispersion state X becomes extremely thin from a place where the covering distance during traveling is small. In the spraying in the house, the compost scattered and scattered in the lateral direction adheres to the pillars and stains the house.

The outer regulating plate 22 blocks the compost M which is about to scatter and scatter in the lateral direction and drops the compost M inside the compost M, thereby concentrating the compost M and reducing an extremely thin portion. or,
By changing the position of engagement of the chrysanthemum seat 29 at the upper end of the regulating plate 22 and increasing the opening angle, the range of spreading the compost M is widened.

On the other hand, in the embodiment, the inner regulating plate 21 is fixed near the blade 20 of the disk type beater 15 so as to follow the rotation trajectory thereof. And spread by the blades 20 to spray from the central part of the spray port S to concentrate the compost behind the machine. At that time, the inner regulating plate 21
Is fixed near the blade 20 of the beater, so that the compost M does not continue to adhere and the compost M does not drop off from this portion. This blocks the compost M to be adhered from the mounting portion of the outer regulating plate 22 to the central portion, thereby reducing the amount of the compost M that adheres to the regulating plate 22 and falls down, and alleviates the streaky plastering.

As shown in FIGS. 1, 2 and 5, an upper regulating plate 60, which is narrower than the width of the spray port S, is provided at the rear lower end of the top plate 17 which defines the upper edge of the spray port S. ing. In the embodiment, the size is such that it covers about 2/3 of the width of the spray port S. As shown in FIG. 5, the regulating plate 60
It has a box-like shape, and has an upper end extension, a chrysanthemum seat 61 provided on both sides, and a chrysanthemum seat 62 provided on a bracket 67 fixed to the rear lower end of the top plate 17 to have an arbitrary opening angle. It is fixed with a bolt 63 so that it can be adjusted.

A locking plate 69 having a hole 66 is provided on both sides of the rear end of the lower casing 16 so as to protrude therefrom.
In order to loosen the control plate 3 and lower the control plate 60 to the “closed” state, the pin 64 provided on the upper control plate 60 is inserted into the hole 66 of the locking plate 69 and fixed. The pin 64 is urged toward the hole 66 by a spring 65 via a pin 68.

Therefore, various effects can be obtained by combining the opening angles of the regulating plates 60, 21 and 22 provided near the spray port S. That is, the regulating plate 60 is fixed in a half-open state by being inclined downward from the horizontal, and
When the folds 1 and 22 are folded (opened) or removed, the compost from the center of the spray opening S scattered far away from the rear of the machine is blocked by the regulating plate 60, collides and falls near the rear of the machine. or,
From the place where the regulating plates 21 and 22 do not act, it becomes a wide scattered state.

Further, as shown in FIG. 7, the upper regulating plate 60 is fixed in a half-open state by being inclined downward from the horizontal, and the inner regulating plate 21 is positioned near the blade 20 of the disk type beater 15 and along the rotation locus thereof. When the fixed outer fixing plate 22 is parallel to the traveling direction of the airframe, in addition to the action of the upper restricting plate 60, the outer restricting plate 22 blocks the compost M which is supposed to be scattered and scattered in the lateral direction, and falls into the inside thereof. By concentrating the compost M, it is possible to obtain a sprayed state in which the spread width is narrow and the density is uniform.

Further, when the upper regulating plate 60 is fixed to the "closed" state and the regulating plates 21 and 22 are folded (opened) or removed, as shown in FIG.
′ And will not be sprayed on the rear part of the aircraft. This is suitable when compost is required only at the root of the fruit tree, such as in the application of compost in an orchard or the like.
