いう不具合がある。Conventionally, there is a rice transplanter equipped with a fertilizer applicator for arranging a plurality of sets of fertilizer hoppers having a fertilizer feeding part side by side in the left-right direction. When carrying the fertilizer hopper, the left and right outermost sides of the fertilizer hopper project from the bed, and the rice transplanter cannot be carried easily as the number of rice transplanters increases. Therefore, there is a means to fold the outermost part of the fertilizer hopper by dividing it, but in the structure with an air tank etc. that conveys the fertilizer in the hopper by air flow, for example, only the fertilizer hopper can be removed separately. There was a problem that it took time and labor to carry out storage and maintenance inspections, which was not easy. Further, if the structure is such that it can be easily removed, there is a problem that the folding structure of these hoppers, air tanks, etc. becomes complicated.

ものである。SUMMARY OF THE INVENTION Therefore, according to the present invention, a plurality of sets of fertilizer application hoppers having a fertilizer feeding section and an air tank for conveying the fertilizer of the hoppers by an air flow are arranged side by side in the lateral direction of the traveling vehicle. In the fertilizer applicator of the rice transplanter, a folding fulcrum member is provided to store and rotate the outermost hoppers and air tanks on the left and right sides inside the machine by rotating and sliding them together, and remove the left and right outermost hoppers and air tanks each time. The work is performed easily without any trouble, and is sufficiently moved to a storage position inside the machine body that does not hinder the operation, thereby reducing the number of man-hours required for folding and improving workability in transportation and storage work.

である。Further, when the left and right outermost hoppers are expanded to the working position, the support frame of the hopper and the support frame of the fixed hopper on the center side are fixedly connected to each other via a one-touch type mounting member, so that only the hopper can be easily mounted. Although the structure is such that the hopper on the detaching side is detached, the hopper on the detaching side can be easily and surely fixedly connected to the hopper on the fixed side at the time of work, thereby making it possible to perform good fertilization work without adverse effects of folding the hopper.

(42) and the fertilizer application device of the rice transplanter, which are arranged side by side in the left-right direction of the traveling vehicle, are left and right outermost hoppers (371) (372) and air tanks (421) (4).
Since the folding fulcrum member (128) that integrally rotates and slides 22) is housed on the inner side of the airframe, the left and right outermost hoppers (371) (372) and the air tank (421) are provided. (422) can be easily moved without the trouble of removing it each time, and can be moved sufficiently to the storage position on the inside of the machine that does not hinder the operation, and the man-hours for folding can be reduced. It is possible to improve workability in such cases.
