【0033】Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter having, for example, a seedling mounting table and planting claws for continuously performing seedling planting and lateral fertilization. [0002] Conventionally, a plurality of sets of hoppers and feeding cases are juxtaposed in the left-right direction to form a fertilizer application section. There is a problem that it cannot be transported easily due to the large size of the planting and fertilizing sections. Therefore, by forming the fertilizing part by the central fixing part and the left and right storage parts, the left and right widths of the fertilizing part can be reduced by mounting the storage part and mounted on the transport truck bed. By supporting the storage portion at the storage position with the support member that has been brought out, the support member protrudes from the fertilizer application portion during rice transplanting work, and there is a problem in that the support member becomes an obstacle during seedling splicing or fertilizer replenishment work. Further, if the length of the support member protruding from the fertilizer application section is shortened, there is a problem that the storage portion support load of the support member increases. Further, by connecting the folding fulcrum of the storage section to the base frame for attaching the fertilizer to the traveling vehicle, it is necessary to specially provide a folding fulcrum support structure, and there is a problem that the weight or the size cannot be reduced. Further, by dividing the air tank provided in the fertilizer application part into a fixed side and a storage side and interposing an elastic packing for preventing air leakage at the joint, the lower side of the packing is easily greatly compressed by the weight of the storage side air tank,
There is a problem that the packing is deformed non-uniformly and the function of preventing air leakage on the upper side of the packing is easily deteriorated. [0003] Means for Solving the Problems] However, the present invention is to So設fertilization portion which are juxtaposed a plurality of sets of hoppers and feeding the case in the lateral direction to the traveling vehicle, fixing the fertilization portion central parts and formed by the left and right sides of the housing portion, to fix the housing portions of the left and right sides in vehicle body in a retracted position, in the lateral width direction of the fertilizer portion
Rice planting to provide a folding fulcrum for the storage part in the extending fixed part
In the machine, the fixing bracket is fixed integrally to the fixing part,
Fix the movable bracket integrally to the storage
Folding fulcrum to be able to rotate and slide freely through the long hole
The movable fulcrum is pivotally supported by the movable bracket, and the folding fulcrum is
Rotate the storage part horizontally around
The storage part is moved horizontally, and also serves as a fertilizer application part component.
The folding fulcrum support structure can be simplified more easily,
Pacting can be easily achieved. [0006] Embodiments of the present invention will be described below in detail with reference to the drawings.

(382) The (421) and (422) are fixed to the traveling vehicle (1) body at the storage position, and the fertilizer application section (36) is moved in the left-right width direction.
The storage portion (371) (37) is attached to the extending fixed portion (42).
2) Folding of (381) (382) (421) (422)
In the rice transplanter provided with the fulcrum (128),
2) Fix the fixing bracket (125) integrally to the storage
The movable bracket (126) is attached to the parts (421) and (422).
The fixed holes (12)
7) A folding fulcrum (12) that is rotatably and slidably inserted through
8) is rotatably supported on the movable bracket (126).
The storage portion (421) around the folding fulcrum (128).
(422) is rotated horizontally to guide the slot (127).
Therefore, the storage units (421) and (422) are moved horizontally.
Therefore, the folding fulcrum can be used by also using the fertilizer application member (42).
(128) The support structure can be easily simplified,
It can be easily made compact.
