Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer-combined direct sowing machine that can be switched between a fertilizer application state in which fertilizer is sprayed on a field and a seeding state in which seeds such as seeds are sprayed on a field.

[0002]

2. Description of the Related Art In Japanese Patent Application No. 7-299410 filed earlier, a partition plate is detachably provided between a hopper and a feeding mechanism. A rational fertilizer-direct sowing machine capable of performing fertilization and sowing in a single machine by setting the seed dispersal state selectively has been proposed.

[0003]

Since the seed rice is relatively large in grain size and soft, in a state where the seed rice is supplied, the partitioning member narrows down the flow path and guides it to the upper half portion of the rotating roll in the rotational direction. By reducing the chance of damage by reducing the chance of contact with the rotating roll, the seeds can be captured by scooping, so that the seeds can be securely taken into the recessed part of the rotating roll while having few contact opportunities. Have been. Therefore, even coated rice seeds are hardly damaged.

Since the fertilizer is relatively small in grain size and hard, the partition member is removed in the fertilizer supply state to widen the flow path and guide the fertilizer to the upper half of the rotating roll, thereby increasing the chance of contact with the rotating roll. The fertilizer is easily filled in the recess. In other words, two kinds of powdery and granular feed products having different properties can be sprayed in a state suitable for each by mounting and dismounting the partition member. However, there are some problems in the sowing state. That is, since the flow-down route is narrowed as described above, the "bridge phenomenon" in which seeds are clogged at that portion tends to occur, and there is room for improvement. An object of the present invention is to provide a fertilizer-cum-type direct sowing machine in which clogging of seeds at the time of installing a partition member is eliminated, while maintaining the advantage that a plurality of feeds can be supplied by attaching and detaching the partition member. .
