Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanting machine having a seedling table and a planting claw for continuously performing a seedling planting operation.
The present invention relates to a rice transplanter equipped with a mid-mount type fertilizer applicator.

[0002]

In the fertilizer applicator so that the fertilizer in the fertilizer tank is fed to the fertilizer application section by the aerodynamic force from the blower, the air suction port of the blower is usually opened in the horizontal and horizontal directions. However, rainwater, foreign matter, dust, etc. are easily sucked in through the air intake port at the same time, which not only causes clogging of the fertilizer and also causes foreign matter to enter the fertilizer.
It lacked safety.

[0003]

Therefore, according to the present invention, in a rice transplanter in which the fertilizer in the fertilizer tank is fed to the fertilizer application section by blowing air from the blower, the air suction port of the blower is opened downward. By using extremely simple means, it is possible to prevent rainwater, foreign matter, dust, etc. from being sucked in from the air intake port, and to enable good fertilization work without clogging with fertilizer or foreign matter mixed in fertilizer. Is.

Further, by providing a net body at the air suction port, even in the state where light and large foreign matters and dust are flying near the suction port, the suction is surely prevented to improve the dustproof property. At the same time, it is possible to prevent accidental entry of a hand or clothes into the suction port, thereby improving safety.

Further, before being sucked into the air suction port,
Roughly remove rainwater, contaminants, dust, etc. in the front suction air passage,
This is to further improve the dustproof property of the blower when sucking air.
