DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

[Problems to be solved by the invention] For example, Article 8 or 10
In the case of a fertilizer application device of a multi-row rice transplanter such as a bar, when reducing the entire width of the machine when moving or storing, the left and right sides of the fertilizer device along with the planting part are folded down by the same length and the total width is reduced. There is a means to make it happen. However, in the case of such a double-sided folding means, the processing cost is high, the parts at the joints and the like are required to have high precision, and the number of working steps is large, which is extremely poor in economical efficiency and workability.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a fertilizer apparatus equipped with a traveling vehicle equipped with a fertilizer apparatus for transporting fertilizer in a hopper with an air flow from an air supply pipe of a blower to apply fertilizer. The fertilizer device is offset to the left and right one side with respect to the center of the traveling vehicle, and the offset side end of the fertilizer device is foldably provided on the main body side. Approximately halved to improve economy and workability.

In addition, the offset side end of the fertilizer is provided so as to be foldable in front of the fertilizer, so that the fertilizer can be compactly and easily folded without being bulky upward.

In addition, the air supply pipe is separated and independent on the fixed side and the folding side of the fertilizer, so that the inconvenience of separating or joining the air supply pipe every time the fertilizer is folded or expanded is eliminated. The purpose of the present invention is to improve the efficiency of folding or expanding work.

[0006] Further, a blower is provided on each of the fixed side and the folding side of the fertilizer application device to eliminate air leakage and the like during fertilizer conveyance by an air flow, thereby performing high-precision conveyance of fertilizer.

Further, a fertilizer application moving mechanism for moving the whole fertilizer application apparatus to the folding side after folding is provided, so that not only the one-side folding of the fertilizer equipment has economical and workability effects, but also the left-right balance of the fertilizer application apparatus is maintained. The purpose is to improve the stability of the fuselage.

Further, a lock device is provided for holding the fertilizer applicator stationary at a predetermined position after moving to the folding side, so that the left and right balance of the fertilizer applicator after folding can be reliably maintained, thereby improving workability in moving or storing work. Is to improve.
