DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter having, for example, a seedling mounting table and planting claws for continuously performing seedling planting operations.

[0002]

2. Description of the Related Art As shown in the specification of Japanese Patent Application No. 6-95595, a technique has been developed for mounting a mid-mount type fertilizer on a traveling vehicle so as to be able to move up and down.

[0003]

The prior art has a structure in which the air tank is raised and lowered together with the fertilizer application hopper and the fertilizer feeding case, so that the weight of the lifting part cannot be easily reduced, and the fertilizer hopper and the fertilizer feeding case are raised. There is a problem that it is not easy to improve the workability of removing the residual fertilizer from the hopper and the workability of maintenance inside the case.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a fertilizer application hopper for storing fertilizer, a fertilizer feeding case for quantitatively feeding the fertilizer from the hopper, and an air supply for conveying the fertilizer from the case. In rice transplanters with air tanks,
The air tank is fixed to the machine side, and the fertilizer application hopper and the fertilizer feeding case are integrally mounted so as to be able to move up and down integrally.The rising parts of the hopper and the case etc. can be formed lighter than before,
It is possible to easily improve the residual fertilizer removal workability and maintenance workability performed by raising the hopper and the case, and to easily simplify and reduce the weight of the lifting and lowering support structure of the hopper and the case. .

Further, a plurality of multi-row fertilizer feeding cases are connected by the same frame, and each fertilizer feeding case is attached to a support via the frame. Only the frame is supported on the support so as to be able to move up and down. Thus, each fertilizer feeding case can be supported so as to be able to move up and down freely, and there is no trouble of individually raising and lowering each fertilizer feeding case, so that the support structure of the fertilizer feeding case can be simplified and handling operability can be easily improved.

In addition, the air tank and the column are integrally fixed to the frame of the machine, and the frame of the machine and the air tank are connected by connecting the frame of the machine extending in the front-rear direction and the air tank extending in the left-right direction. The strength can be mutually improved, and a light, compact and sufficiently strong support structure for supporting columns can be easily formed.

[0007] Further, there are provided two front and rear frames having substantially the same length as the installation width of a plurality of fertilizer feeding cases for multiple use, and the front and rear portions of each fertilizer feeding case are fixed to the front and rear frames.
The lifting load can be easily prevented from increasing due to the weight of the hopper and the case acting as an offset load, and the hopper and the case can be smoothly moved up and down without tilting back and forth.
