Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer applicator for a rice transplanter, which simultaneously applies fertilizer along the lines of seedling planting work.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Publication No. 54-20350, there has been a technique for fertilizing at the same time as planting seedlings.

[0003]

In the above-mentioned prior art, since the grooving body is provided at the portion where the mud flow is fast at the rear end of the wide front half of the planted float, the mud flow flowing as a guide by the grooving body. As a result, there is a problem that the seedlings that have already been planted are easily fallen down, and the fertilizer that has fallen due to the swirling flow that tends to occur at the rear end of the ditch body flows out.

[0004]

SUMMARY OF THE INVENTION However, the present invention is to planting float wide front half portion bottom for the planting plan located Hitoshitaira is fixedly provided Sakumizotai front, planting float narrow rear half and by disposing the operation Mizotai rear fertilizer fall portion between the planting shoots, also when Ru is integrally connected fertilizer falling portion at the rear the operation Mizotai
Both, the fertilizer tank for multi-row and the feeding section as one set of two articles
A fertilizer frame is fixed to the running car body at approximately the same height.
K, and one feeding input shaft in the left-right direction that arranges the feeding parts side by side.
The clutch that is provided with 2 sets of driving force of the feeding section
Is provided in the middle of connecting the feeding section and the feeding input shaft,
Fertilizer guide pipe that connects the respective fertilizer dropping parts of the feeding part and the planting part
The planting float and fertilizer drop embedding can be performed at the bottom of the wide front half of the planting float and at the slow mud flow part in the narrow second half of the planting float. Fertilization work performed at the same time can be easily prevented from adversely affecting the planting shoots, and the fertilizer dropping part is integrally fixed to the rear part of the ditch body where the front part is fixed to the wide front half part of the planting float. from comparison with a structure in which immobilized utilizing planting float side, Sakumizotai and easily performed to obtain and simplified shapes and mounting structures of fertilizer fall portion, further wherein
Run fertilizer tank and feeding section by installing fertilizer frame
It can be easily attached to the vehicle body and the driving force of one feeding input shaft can be
The clutch can be transmitted freely by the clutch, and the clutch can be stopped.
It is possible to use fertilizer effectively by operating the
Extend the fertilizer guide tube between the body and the planting section to store the fertilizer in the feeding section.
Since it is carried out to the fertilizer drop section, it is possible to increase or decrease the fertilizer in the fertilizer tank.
Therefore, it is easy to prevent the planted float ground pressure from changing.
In addition, it is necessary to obtain the fertilizer and replenish the fertilizer tank with fertilizer.
Is easily done obtained shall by the operator of the above.
