Description

[Detailed description of the invention] This invention relates to the improvement of a compost removing machine, and by providing a pair of left and right flower-shaped rotors oppositely behind the compost delivery port, it is possible to improve the compost spreading operation and remove the spread compost. The purpose is to enable soil covering and ridge formation to be performed continuously in the same work process.

That is, in the present invention, a dispensing cylinder is protruded downward from the front end of a discharge port that opens at the bottom of the storage hopper, and a dispensing conveyor is provided facing the discharge port, and the drive shaft of the conveyor and the support shaft of the grounding wheel are The sprocket wheels are each mounted on an axis, and a chain is stretched between both sprocket wheels.
At the rear of the feeding tube, a pair of left and right flower-shaped rotors are arranged in an approximately eight-shape shape, with an interval slightly larger than the opening width of the feeding tube, and gradually narrowing from the front to the rear. The gist of the book is as follows.

Hereinafter, specific embodiments of the present invention will be described with reference to the illustrative drawings. In the drawing, 1 is a towing tractor, 2 is a compost spreader connected to the rear of the tractor 1 via a towing hitch 3, 4 is a frame, and 5 is a compost spreader supported across both width directions of the frame 4. The support shafts 6 and 6 indicate a pair of left and right ground wheels mounted on both ends of the support shaft 5. Reference numeral 7 designates a sprocket wheel which is also mounted on a shaft near one end of the support shaft 5. 8 shows a compost storage hopper placed on the frame 4. The hopper 8 has an opening at its upper end and is formed into a funnel shape that gradually narrows downward from the upper end, and at the bottom of the hopper 8 there is a wide-opening drain in the front and back direction. The outlet 8' is opened. At a position near the front end of the discharge port 8', a dispensing tube 9 that opens the dispensing port 9' downward is provided so as to protrude downward from the base of the dispensing tube 9 so as to gradually become narrower as it goes downward. A delivery conveyor 11 is provided so as to be freely rotatable in the front-rear direction in correspondence with the conveyor 8'. And the drive shaft 1 of the feeding conveyor 11
0, a sprocket wheel 12 is mounted on the shaft in correspondence with the sprocket wheel 7. A chain 13 is stretched between the sprocket wheels 7 and 12 so that the rotation of the ground wheels 6 and 6 is transmitted to the delivery conveyor 11.

Reference numerals 14 and 14 denote mounting plates fixed at symmetrical positions via a pair of upper and lower support frames 15, 15 extending across both width directions of the frame 4; A supporting cylinder 16, 16 having a plurality of engagement grooves 16' endlessly provided along the circumferential direction is fixed to one end of the side, and supporting rods 17, 17 are fixed to the supporting cylinder 16, 16. The stoppers 18, 18 are inserted through the engagement grooves 16' so as to be freely forward and backward and rotatable in the left and right directions. 18 into the above-mentioned engagement groove 1
By selectively engaging inside the support rods 17, 17, the mounting angle of the support rods 17, 17 can be arbitrarily adjusted.
17' is provided, and the same step parts 17', 17' and the support plate 1 are provided.
Springs 19, 19 are interposed between the rear surfaces of 4, 14, and the support rod 1
7 and 17 are normally biased toward the rear, and the stoppers 18 and 18 are forcibly elasticized into any engagement groove 16' through the biasing action of the springs 19 and 19. Do what you feel supported.

Support legs 20, 20 are fixed downward to the support rods 17, 17, and a pair of left and right flower-shaped rotors 21, 21 are attached to the lower ends of the support legs 20, 20, with the distance between the two rotors 21, 21 being the same as that of the feeding tube 9. It has a dimension slightly larger than the opening width, and is freely rotatable so that it gradually narrows from the front end toward the rear end with respect to the center line in the traveling direction, so that it is arranged in a roughly eight-shape shape. It is made of bearings. In other drawings, 22 indicates support plates 14, 14 and frame 4.
A shock absorbing spring stretched across the space is shown.

Next, its effect will be explained.

FIG. 1 shows a state in which a spreader with compost loaded in a hopper 8 is being towed by a tractor 1. As the spreader is towed, the support shaft 5 that supports the grounding wheels 6, 6 rotates together with the grounding wheels 6, 6, but the rotation of the support shaft 5 is caused by a pair of sprockets. The transmission is transmitted to the drive shaft 10 through the sprocket wheels 7, 12 and the chain 13 stretched between the sprocket wheels 7, 12, and through the rotation of the drive shaft 10, the feed conveyor 11 is moved so that its conveying surface is connected to the hopper. 8, along the discharge port 8' from the rear direction to the front end direction. The compost in the hopper 8 is conveyed toward the front end through the forwarding action of the conveyor 11, and the compost conveyed to the front end is transferred to the feed tube 9.
After that, they fall to the soil surface one after another.

However, the compost that fell onto the soil surface in this way is transferred to the following flower-shaped rotors 21, 21 without any time delay.
Through the plowing action, the soil is sequentially covered with soil, and small ridges are formed by the covering soil.

In addition, when the flower-shaped rotors 21, 21 are not used, the support rods 17, 1 in the state shown in FIG.
7 in the forward direction against the biasing force of the spring 19, the engagement groove 1
The stopper 18 that was engaged in the groove 1
6', the support rods 17, 17 can freely rotate in the left and right directions. Then, after rotating the support rods 17, 17 in the free state in the right direction in the same drawing, that is, through an angle of approximately 90 degrees as shown by the dashed line, the support rods 17, 17 so far are rotated.
If the pressing state of 17 is released, the support rod 17,
17 is biased rearward by the action of spring 19, and stopper 18 is engaged in any groove 16', thereby securing it in that position.

The present invention has the above-mentioned configuration, and as described above, the hopper 8 is placed on the frame 4 of the sprayer, and the bottom of the hopper 8 has a wide outlet 8' extending in the front and back direction. A feeding tube 9 is provided facing downward at the front end of the discharge port 8', and a feeding conveyor 11 is provided along the discharge port 8'.
The feeding conveyor 11 rotates together with the support shaft 5 of the ground wheels 6, 6, and a pair of left and right flower-shaped rotors 21, 21 is installed at the rear of the feeding tube 9, and the distance between the two rotors is larger than the opening width of the feeding tube 9. By arranging them in a substantially eight-shape shape, which has a slightly larger dimension and gradually narrows from the front to the rear, it is possible to maintain a substantially constant width without scattering from the feeding tube 9. It has become possible to cover the soil with the compost spread on the soil surface in an optimal state through the plowing action of the flower-shaped rotors 21, 21 without any time delay.

As a result, it has become possible to promote the fermentation and decomposition of compost in the soil, and to prevent the compost from escaping due to drying.

In addition, in the present invention, a pair of left and right flower-shaped rotors 21, 21 are arranged at the rear position of the feeding tube 9 to perform the soil covering work as described above, so that the compost can be spread quickly in one stroke. This makes it possible to cover the soil with soil, thereby significantly improving the work efficiency, and at the same time, it is possible to immediately obtain a small ridged state at the same time as covering the soil.

Furthermore, in the present invention, as mentioned above, the feeding conveyor 11 is provided at the bottom of the hopper 8, and the compost is spread through the conveyor 11, so that a uniform amount of compost can be fed out, and All of the compost can be completely fed out without any remaining compost inside the container. Furthermore, in the present invention, by driving the feeding conveyor 11 through the rotational power of the support shaft 5 that supports the ground wheels 6, 6, it is possible to obtain a feeding amount that corresponds to the towing speed of the spreader. The practical effect in this respect is extremely large.
