Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-row transplanter for transplanting plants to be transplanted such as vegetable seedlings into a field with a plurality of planting lines.

[0002]

2. Description of the Related Art Conventionally, this kind of multi-row transplanter is provided with a plurality of seedling table frames corresponding to a plurality of planting articles, and these seedling table frames accommodate a large number of transplanted plant bodies. Is so constructed as to be able to be transported, and the transplanted plants to be transported by these seedling trays are transplanted one by one.

[0003]

However, in the conventional multi-row transplanting machine, since a plurality of seedling table frames corresponding to a plurality of planting rows are individually formed, the structure is complicated and the assembling workability is improved. However, there was a problem that the cost was high, and because the seedling table frame had a fixed structure, it was not possible to change the spacing between the planting strips.

The present invention provides a multi-row transplanter capable of simplifying the structure of the seedling mount frame in the multi-row transplanter and easily changing the seedling tray spacing when changing the planting row spacing. The main purpose is to do.

[0005]

In order to achieve the above-mentioned object, the present invention according to claim 1 is, as shown in FIG. 1, an object to be conveyed by a seedling tray corresponding to a plurality of planting lines. In a multi-row transplanter for transplanting a transplanted plant, a fixed seedling mounting table 91 having a fixed transfer path of a seedling tray and a transfer path of a seedling tray in a width direction orthogonal to the transfer direction on a seedling mounting table frame 9. A movable seedling mount 92 that can be displaced is provided.

Further, in order to enable the transport locus of the seedling tray supported on the movable seedling placing base 92 to be accurately set, the movable seedling placing base 9 as shown in FIG.
In FIG. 2, a positioning body 94 that sets the transportation path of the seedling tray is provided.

Further, in order to make it possible to easily change the planting strip interval, the invention according to claim 3 is to transfer the plant from the seedling tray of the movable seedling mounting base 91 as shown in FIG. The seedling taking section 10 for taking out the body and the planting section 20 for planting the plant to be transplanted taken out from the seedling taking section 10 are slid in correspondence with the displacement position of the seedling tray of the movable seedling placing table 92. I chose

[0008]

According to the first aspect of the invention, the seedling stand frame 9 is provided.
In addition, since the fixed seedling mounting base 91 and the movable seedling mounting base 92 are provided, the structure of the seedling mounting base frame 9 can be simplified and assembled as compared with the case where the seedling mounting base frame 9 is individually provided.
