Description

Detailed Description of the Invention "Industrial Application Field" The present invention relates to a hopper having a built-in feed-out roll that continuously delivers a certain amount of seeds (seed rice), a sowing chute connected to the hopper, and a sowing chute for sowing. The present invention relates to a flooded direct sowing machine that is equipped with a soil leveling body that forms grooves, and sows seeds in a flooded field after puddling.

``Prior Art'' Conventionally, as shown in Japanese Patent Publication No. 50-30523, a feed roll is provided below a hopper into which seeds are placed, a seeding chute is provided below the roll, an engine is placed in front of the machine body, and a running wheel is provided in the middle. There was a walk-behind direct sowing machine with a steering handle at the rear.

"Problems to be Solved by the Invention" In the prior art, a feed roll was provided on the same axis as the running wheel, and a seeding chute was installed vertically below the roll, so it was not possible to achieve a good single-wheel, two-row seeding structure. Although the balance of the aircraft was achieved, in large models with two running wheels, left and right, the running transmission structure becomes complicated, and this simplification cannot be easily achieved. There were structural problems, such as the fact that the weight was likely to be heavier than that of the conventional method, and it was not easy to increase the number of strips.

Therefore, Utility Model Publication No. 44-4098 and JP-A No. 53-
As shown in each publication of No. 103807, there was a technology in which a hopper for putting seeds in and a seed delivery roll were arranged at the base of the steering handle, but the hopper and roll were installed as part of the machine between the left and right running wheels. Because of this, it was not easy to obtain a structure in which multiple sets of hoppers and rolls were installed side by side in the left and right direction, and the sowing chute on the left and right sides were longer than the central part below the rolls, resulting in inconsistent sowing timing. In addition to uniformity, there were structural and functional problems such as the tendency for seeds to become clogged.

Furthermore, as shown in Japanese Patent Application Laid-Open No. 54-15813, there is a technique in which a hopper for putting seeds in and a seed delivery roll are located in front of a sowing chute, but when viewed from the rear, the hopper and roll are placed within the outer shape of a soil leveling body. Since the soil leveling body is not placed above and the outside of the soil leveling body is not positioned outside of the traveling wheels, there are problems in handling operations such as preventing rolling of the machine body with the leveling body and not being able to maintain equal sowing depth on the left and right sides. There were also functional problems.

``Means for Solving the Problems'' However, the present invention provides a walking type system in which a seed feeding roll is provided at the bottom of a hopper into which seeds are placed, and the seeds from the roll are guided to drop into a seeding groove of a land leveling body by a seeding chute. In the flooded direct seeding machine, the outer side of the soil leveling body is arranged outside the running wheels, and the hopper and roll are located in front of the chute when viewed from the side, and the outer shape of the soil leveling body when viewed from the rear. It is characterized by being placed above this within the interior.

``Function'' Therefore, since the hopper and roll are located at the front side of the chute in side view, the hopper and roll can be installed as close to the front of the machine body as possible behind the running wheels, and the longitudinal balance of the machine body can be maintained. It is possible to easily support multiple sets of hoppers and rolls side by side in the left and right direction without making major changes, and it is possible to easily achieve multi-strip size of a walking type aircraft while maintaining the front-rear balance of the aircraft, as well as more easily than before. By making the supporting heights of multiple sets of hoppers and rolls approximately the same so that all the seeding chutes have uniform lengths, they can be constructed between the rolls and the seeding point at the shortest possible distance, and the seed movement time within each seeding chute is reduced. It is possible to make the timing of multi-row sowing uniform by making it almost the same, making it easier to make the timing of multi-row sowing uniform, etc. with simpler adjustment operations and maintenance than before. On the other hand, since the hoppers and rolls are arranged within the outer shape of the land leveling body, the land leveling body does not act as a side bumper on ridges, etc. when working on headlands. The hopper and roll can be protected, and the hopper and roll can be safely spread and moved on the road.Moreover, since the outer surface of the soil leveling body is placed outside the running wheels, the rolling of the machine body during sowing work can be prevented by the grounding of the soil leveling body. It is possible to prevent this from happening, and it is possible to easily improve handling operability and sowing function by keeping the sowing depth uniform on the left and right sides.
