Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a seedling transplanter in which the width of a seedling transplanted in one stroke is wider than the width of a running vehicle body. 2. Description of the Related Art A large-sized seedling transplanter is configured such that a wide-width seedling-planting device is attached to a running vehicle body having a narrow width, and the seedlings are transplanted in multiple rows in one stroke. ing. For this reason, the lateral end of the seedling plant protrudes remarkably from the running vehicle body, and storage and transportation are inconvenient. [0003] In order to solve this problem,
Various proposals have been made, but still not enough. [0004] In order to solve the above-mentioned problems, the present invention is directed to a seedling plant frame 33 having a planting claw 38 provided at a rear portion of a traveling vehicle body 1 and right and left sides of the seedling plant frame 33. A side frame 35 disposed on the side and provided with an implantation claw 38 at the rear is provided below the seedling mounting table 29 inclined forward and upward, and the seedling planting frame 33 and the side frame 35 are provided.
In the seedling plant equipped with the seedling plant 2 provided with a plurality of floats 57 arranged side by side below, the outer side of the seedling table 29 is folded on the seedling table 29, and the side frame 35 is planted. In addition to the configuration in which it is folded on the frame 33, the depth adjustment shaft 48 provided in the lower part of the seedling frame 33 and the side adjustment shaft 50 provided in the lower part of the side frame 35,
By adjusting the rotation of 50, the rear end of the plurality of floats 57 and the distance between the seedling plant frame 33 and the side frame 35 are changed to adjust the planting depth of the seedlings.
This is a seedling planting machine in which 0,50 can be separated from the depth adjusting shaft 48. [0005] Therefore, the seedling mounting table 29 and the side frame 35 of the seedling planting apparatus 2 are brought into a seedling transplant operation state, and the side adjusting shaft 50,
If 50 is connected to the depth adjusting shaft 48, the seedling frame 33 and the planting claws 38 provided at the rear of each of the side frames 35 disposed on the left and right sides of the seedling frame 33 can be mounted on the seedling mounting table. By transplanting the seedlings placed on the plant 29 into a field, transplantation of a plurality of seedlings significantly wider than the width of the traveling vehicle body 1 can be performed in one stroke. Further, when the depth adjusting shaft 48 is rotated by a lever operation, the depth adjusting shaft 48 and the side adjusting shafts 50, 50 connected to the depth adjusting shaft 48 are rotated to operate the float 57.
