[Problems to be Solved by the Invention]

As described above, if the entire sub-soiler passage traces are filled with rice husks, the rice husks filled in the vertical cutting blade passage traces (vertical grooves) prevent the vertical grooves from being crushed from both sides, and the water above is moved downward. Although it acts as a guide, filling the rice husk in a deep horizontal hole formed by a chisel or shell has a problem that water moves laterally, that is, drainage performance deteriorates. In particular, when the lateral holes are formed cleanly by the soil, filling the rice husk rather deteriorates the drainage function, and it is often better not to fill the rice husk. The present invention has been made to solve the above problems,
An object of the present invention is to provide a rice husk addition device in which the rice husk is filled only in the traces of passage of the vertical cutting blade, and the structure therefor is improved.

Rotational power is transmitted from the PTO shaft of the tractor to the input shaft 5 which is provided and projects forward from the vibration mechanism 4 mounted on the main body 1. The vibrating arm 6 extending rearward from the vibrating mechanism 4 includes a vertical cutting blade 7 extending downward.
A chisel 8 attached to the lower end of the vertical cutting blade 7 in the front-rear direction and a shell 9 attached to the rear end of the chisel 8. Further, the machine body 1 is provided with front wheels 10, a gauge wheel 11, a stand 12, etc., and constitutes a conventionally known subsoiler. Above the subsoiler, a rice husk hopper 15 is attached via support arms 13 and 14. The bottom plate of the hopper 15 is inclined in the front-rear direction so that the rear part faces downward, and an opening 16 is provided in the lower inclined part of the bottom plate.
The operation handle 18 of the shutter 17 for opening and closing the
It projects to the front side of. The operation handle 18 is provided at a position where a worker who rides on the tractor can operate it while facing backward. A flexible pipe 19 is connected to the opening 16, the lower end of which guides the chaff along both sides of the vertical cutting blade 7,
The vertical cutting blade 7 faces the upper end of the guide 20 for filling the rice husk into the vertical groove formed in the field. The guide 20 is a plate-like body whose front end extends along the vertical cutting blade 7, extends rearward, and has its rear end opened with a width slightly wider than the thickness of the vertical cutting blade 7. A slide cover 22 that can be moved up and down by a thumbscrew 21 is provided on the. Further, the lower end of the guide 20 is squeezed so as to approach the vertical cutting blade 7 to form a narrowed portion 20a, and the lower end of the guide 20 and the chisel 8 and the shell 9 are separated from each other by the vertical cutting blade 7. It suffices that the chaff to be filled in the groove be formed so as not to fall into the lateral hole formed by the chisel 8 and the shell 9, and as in the embodiment, a spacing of about half the diameter of the shell 9 is desirable. In the rice husk addition device having such a configuration, the vertical cutting blade 7 (guide 20) and the chisel are attached to the tractor through the top mast 2 and the lower link pin 3, and the oscillating mechanism 4 receives power from the input shaft 5. 8, the shell 9 and the guide 20 vibrate slightly in the front-rear direction at a high speed, and are pulled by the tractor to be cut by the vertical cutting blade 7, the chisel 8 and the shell 9 to the drainage vertical groove 23 in the field as shown in FIG. And the lateral hole 24 is formed by providing a narrowed portion. On the other hand, the rice husk M stored in the rice husk hopper 15 is
The shutter 17 has its opening adjusted by 18, and the rice husk M has an opening.
It is supplied into the guide 20 through the flexible pipe 19 through 16. Then, the rice husk M is discharged into the vertical groove 23 formed by the vertical cutting blade 7, and the horizontal hole 2 is formed by the narrowed portion 20a.
Almost never falls within 4. Further, the height of the rice husk M supplied into the vertical groove 23 is performed by the slide cover 22 which is vertically adjusted by the thumbscrew 21, and by the height adjustment, the rice husk M is filled in the vertical groove 23 of the cultivated land portion. Will not be done,
When cultivating the cultivated soil in this portion, the rice husks are prevented from being mixed into the cultivated soil. As shown in FIG. 5, when the guide 20 is provided with the reinforcing plate / rice husk chute 25, the strength of the guide 20 in the width direction is increased, and the rice husk M is filled in the vertical groove 23 more smoothly.

【The invention's effect】

As described above, according to the rice husk addition device of the present invention,
A guide 20 is provided, which extends along the left and right side surfaces of the vertical cutting blade 7 and extends backward for a predetermined distance, communicates with the hopper 15 at the upper portion and has a space for filling the rice husk M, and the lower end of the guide 20 is provided with a chisel 8 and a shell. The rice husk M is narrowed just above 9 so that the rice husk M does not drop, and the vertical cutting blade 7, the chisel 8, the shell 9 and the guide 20 for filling the rice husk M are vibrated in the front-back direction.
Since the narrowed portion 20a is provided at the lower end of the guide 20, the rice husk M is filled in the vertical groove formed by the vertical cutting blade 7 and is hardly filled in the lateral hole formed by the chisel 8 and the shell 9, so that the vertical groove is It is prevented from being crushed from the left and right by the rice husk, and the water accumulated in the upper part of the field for a long period can be discharged downward through the vertical groove. In addition, since the horizontal holes are not filled with the rice husk M, the water permeability is good, and the drainage from the vertical groove can be guided to the outside of the field and discharged. Further, since the guide 20 also vibrates along with the vibration of the subsoiler, the required power can be reduced and the rice husk M can be reliably supplied into the vertical groove. Further, since the narrowed portion 20a is provided in the lower portion of the guide 20, the rice husk M is filled only in the vertical groove and does not fall into the lateral hole.
