DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

In a spraying apparatus which spreads a granular material such as a granular fertilizer or a chemical by rotation of a spinner and uniformly disperses it through a spreading cover or the like, a power source such as a battery is used. (Power supply), and there was an inconvenience that it could not be mounted on a recoil type rice transplanter without a battery.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a spraying apparatus for a rice transplanter provided with a granular material dispersing device behind a planting section, in which the lateral width of a granular material feeding roller provided below a granular material hopper is reduced. The spinner is driven by using a power supply by linking a feeding roller to a planting drive mechanism for driving a seedling planting claw while having a width substantially equal to the width of one or a plurality of planting stands on the mounting table. The present invention does not complicate the conventional structure, and uses a drive mechanism of a seedling-claw to perform good uniform spraying of granular materials such as drugs and fertilizers at low cost.

[0004] Further, the feeding roller is driven in units of each planting case for mounting the seedling planting claws. When the unit clutch provided in the planting case is driven or stopped by driving or disengaging the unit clutch, the feeding roller is driven. In response to this, the spraying device is also driven or stopped, thereby enabling efficient spraying without waste of fertilizers and chemicals.

[0005] Further, compared to a configuration in which delivery slots formed on the outer peripheral surface of the delivery roller are arranged in a staggered manner, for example, the slots are arranged in parallel, shading and blank areas are generated in the granular material scattering layer in the field. In this case, the spraying of the fertilizer and the chemicals is prevented, and the spraying of the fertilizer and the medicine is carried out almost uniformly and favorably, thereby improving the productivity of the crop.
