Description

[Detailed description of the invention] A. Industrial application field This invention relates to a frame for increasing the compost loading capacity of a compost spreader.

B. Conventional technology Conventionally, in a compost spreader, a multi-board frame with open top and bottom surfaces was installed above the original compost loading device to increase the amount of compost loaded and the amount of compost spread per loading. This was what was being done.

C. Problems that the invention aims to solve However, with a simple multi-board frame with open top and bottom surfaces, the conveying mechanism for transporting compost to the spreading device installed on the inner bottom of the loading device requires additional stacking within the same frame. The disadvantage is that the added weight of the compost prevents the smooth operation of the mechanism, and that the compost at the bottom of the device is compacted, resulting in a difference in spreading density at the beginning and end of the spreading process, making it impossible to spread uniformly. It was hot.

D. Means for solving the problem In this invention, a large number of slanted plates tilted downward in the conveying direction of the conveying device are installed at appropriate intervals, inside a removable multi-board frame on the top of the compost loading device. It is an object of the present invention to provide a structure of a frame for increasing the compost loading capacity of a compost spreader, which is characterized by the following features:

E. Effect With the above structure, the weight of the compost in the board expansion frame is partially supported by the swash plate, reducing the pressure on the conveyance mechanism, and the downward inclination of the swash plate in the conveyance direction allows the compost to be transferred in the conveyance direction. A component force is generated to assist the conveying action, which makes the operation of the conveying mechanism smooth, and since the swash plate supports the weight of the compost in the multi-board frame, the compost at the bottom is not compacted and is uniformly distributed. Spreading density can be maintained.

F. Effect According to this invention, by configuring the compost loading capacity increase plate frame of the compost spreader as described above, the amount of compost spread per loading can be increased.
This has the effect of smoothing the operation of the conveyance mechanism on the inner bottom of the loading device and making it possible to obtain a uniform spraying density throughout the entire spraying operation.

G. Example The example of the present invention will be explained in detail based on the drawings.
A shows a compost spreading machine, in which a compost loading device 2 is mounted on a frame 1, a spreading device 3 is arranged behind the device 2, and wheels 4 are arranged below the frame 1,
Via the connecting part 5 protruding from the front end of the frame 1,
It is connected to an agricultural tractor (not shown) or the like, and is configured so that the compost m loaded on the loading device 2 is discharged and spread backward by the spreading device 3 while being towed by the tractor or the like and traveling in the field. In particular, in this example,
A board increase frame 6 for increasing the amount of compost loaded is connected to the upper part of the loading device 2 originally equipped in the compost spreader A.

First, to explain the compost loading device 2, a conveyor mechanism 8 in the form of a belt conveyor, which has approximately the same width as the width of the box 7, is disposed on the inner bottom surface of a box 7 with an open top surface. The upper surface of the belt 9 is rotated backward, that is, in the direction of the spreading device 3, and the compost that falls gradually downward in the box 7 and comes into contact with the upper surface of the belt 9 is sequentially conveyed to the spreading device 3. In addition,
Reference numeral 10 denotes a belt drive roller, which is interlocked and connected to a drive gear box 11. The box 11 is interlocked and connected to a PTO shaft of a tractor, etc. via a power intake shaft 12, and is operated by the power from the PTO shaft. It is something to do. Note that 10' indicates a belt support roller.

The dispersion device 3 has a dispersion roller 13 horizontally supported in a pivoted manner at the rear of the box body 7 near the upper rear end of the conveyance mechanism 8, and the roller 13 is interlocked and connected to a drive gear box 11 to control the rotation of the roller 13. The transport mechanism 8
The compost conveyed from the box body 7 is sequentially released and spread behind the box body 7. Reference numeral 14 indicates a spreading blade protruding from the outer circumferential surface of the spreading roller 13, and by forming the blade 14 in a substantially spiral shape, the released and spread compost is spread in the lateral direction.

The plate-increasing frame 6 for increasing the compost loading capacity is configured in a substantially rectangular plate frame shape with front and rear and left and right side plates 15, 16, 17, 18, and the lower edge 6' of the plate-increasing frame 6 is as follows: Box 7 of the original loading device 2 of the same spreader A
It is removably connected to the upper edge 19, and between the left and right side plates 17, 18 of the board expansion frame 6, there is a rear downward
A large number of swash plates 20 inclined at 45 degrees are installed at appropriate intervals. The front plate 15 of the board increase frame 6 is inclined approximately parallel to the swash plate 20, and the board increase frame 6
The top opening is widened.

In this embodiment, the vertical dimension of the board expansion frame 6 is approximately 0.9 m, and the vertical dimension of the original loading device 2 of the spreader A is approximately 0.4 m, so the compost loading amount can be increased by the board expansion frame 6. The weight of the compost in the expansion frame 6 is supported by friction with the upper surface of the swash plate 20 disposed inside the frame 6, and moreover, the weight of the compost in the expansion frame 6 is
Due to the inclination in the conveying direction, a component force is generated in the direction that assists the conveying operation of the conveying mechanism 8 on the inner bottom surface of the loading device 2, so that the smooth operation of the conveying mechanism can be maintained even if the compost loading amount increases by about three times or more. ing. In addition, the swash plate 20
The swash plate 20 and the left and right side plates 1
7 and 18 are close to each other, and the frictional force that resists the downward movement of the compost m acts excessively and obstructs the even downward movement of the compost. Through-holes 21 are provided to reduce the frictional force and maintain even downward movement of the compost. In the figure, 22 is a reinforcing pipe material for the swash plate 20.
