Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter provided with a fertilizer and a chemical sprayer behind a seedling mounting table to perform fertilizer application and herbicide spraying while planting seedlings.

[0002]

Conventionally, in a rice transplanter equipped with a fertilizer applicator behind the seedling mounting table and a chemical sprayer behind the fertilizer applicator, the height of the fertilizer container of the fertilizer applicator is increased. The height of the medicine container of the sprayer was substantially the same or lower. However, in the case of such a structure, the capacity of the medicine container cannot be increased (the lowermost part of the medicine spraying machine needs a space for preventing the medicine spraying machine from contacting the ridge when turning, etc., and there is a limit in reducing the whole. In addition, if the lateral width of the container is widened, the inclination of the bottom of the container becomes gentle, and the flow of the medicine becomes poor.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a rice transplanter equipped with a fertilizer applicator behind a seedling mounting table and a chemical sprayer behind a fertilizer applicator. And the horizontal width of the fertilizer container at the front of the container is larger than the horizontal width of the drug container, so that the medicine can flow naturally without increasing the number of drug containers. The capacity of the fertilizer container can be easily expanded through the space on both the left and right sides of the container from the back of the container, and the upper surface of the container can be easily checked. The present invention is intended to improve the efficiency of the fertilizer replenishment work by utilizing the fertilizer container to easily and surely supply the fertilizer from the fertilizer supply container to the fertilizer container.

Further, the left and right lateral widths of the container lid of the fertilizer container at the front position are provided to be larger than the left and right lateral widths of the container lid of the medicine container, so that the container is not disturbed from the rear side of the machine body without obstructing the medicine container. The fertilizer container lid is opened and closed by inserting hands from both left and right space areas, thereby facilitating the supply of fertilizer and improving the efficiency of fertilizer replenishment work.
