Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a multi-row planting type planting machine.

[0002]

2. Description of the Related Art A seedling planting device is installed after a traveling car body having a seat to form a riding type seedling planting device, and the seedling planting device is configured as a multi-row plant having a wider width than the traveling car body.

[0003]

The seedling planting device is provided with a seedling placing table, and as the seedling transplantation progresses, the number of seedlings on the seedling plant becomes smaller. Then
The assistant replenishes new seedlings on it. If the seedling planting device is constructed in a multi-row type, two assistants ride on both sides of the seat to supplement the seedling planting table with the above-mentioned seedlings. Or
One assistant moves to both sides of the seat to replenish the seedlings. Therefore, in the former case, three people ride on the vehicle body, and it may become heavy and sink in a weak field, or, in order to eliminate this, if the number of spare seedlings placed in advance is reduced, continuous operation time Becomes shorter and work efficiency decreases. The latter requires a passage for the assistant to move from side to side after the seat, and the seedling planting device projects significantly behind the traveling vehicle body, deteriorating the front-rear balance of the seedling planting machine.

[0004]

In order to solve the above-mentioned problems, a seedling planting device 2 is mounted after a traveling vehicle body 1, and the traveling vehicle body 1 has a step 16 beside a seat 8 where an assistant rides. In the planting device 2, a plurality of seedling planting units 19 are arranged side by side to form a multi-row planting, and the seedling placing bases 28 of the respective seedling planting units 19 are placed after the seat 8 with a space therebetween.
8 is a seedling planting machine provided so that the front end can be moved left and right.

[0005]

In the seedling planting machine constructed as described above, the operator sits on the seat 8 and one assistant rides backward on step 16 beside it to operate in the field. Then, the seedlings on each seedling mounting table 28 are sequentially transplanted from the lower (rear) end, and a plurality of seedling rows are formed in the field. As this work progresses, the seedling table 28
Fewer seedlings on top. Then, the assistant, the seedling mount 28
After moving the front end of the seedling to the assistant side and replenishing each seedling mounting table 28 with new seedling from one side of the seat 8, the movement is returned to the original state. Then, new seedlings are added to the edges of the reduced seedlings, and seedlings are continuously transplanted.

[0006]

[Effect] As described above, according to the present invention, seedlings can be replenished by one assistant from one side of the seat 8 with respect to the seedling mounting table 28 having a wide width behind the seat 8, thus improving work efficiency. In addition to being expensive, it is possible to reduce the weight and improve the front-rear balance.
