ことを特徴とする苗植機としたものである。In order to solve the conventional problems, the present invention is provided with a seedling table 9 which is supported by the machine body and reciprocates left and right, and is arranged rearward of the machine body with respect to the seedling table 9. Two seedling planting implements 15 and 15 are attached to a rotating case 14 which is driven and rotated by the drive shaft 13, and the respective seedling planting claws 15a and 15a of the seedling planting implements 15 and 15 rotate the rotating case 14. In the seedling planting machine having a seedling planting device 8 which is rotated so as to take out one seedling of each stock from the seedlings placed on the seedling placement stand 9 and to operate in the field, the rotating case 14 A leveling float 10 for leveling the soil surface for seedling planting by the seedling planting tools 15 and 15 is provided at a lower position than the front part so as to be pivotally supported by a shaft 16 so that the shaft 16 can move up and down. It is provided on the rear side of the body of the vehicle and on the front side of the body of the drive shaft 13, so that the rotating case 14 and the leveling float 10 are Is obtained by a seedling planting machine being characterized in that disposed both in a state that does not interfere with.

I am configuring. In addition, the seedling planting nail 15
The seedling pusher 15b provided on the back side of a is the seedling planting nail 15
It is provided that a moves downward when plunging into the soil surface and transplants seedlings, and then moves upward. It should be noted that it is convenient to make the portion of the transplant locus (i) drawn upwards vertical so as to have a substantially semi-elliptical shape so that dragging of the seedling at the time of transplant can be reduced.

状に構成されている。The central ground leveling float 10 and the side ground leveling float 11 are for leveling the seedling planting positions by the seedling planting device 8, respectively, and the rear part of the horizontal shaft 1 on the transmission case 7 side.
It is pivotally supported by 6, and is attached to the transmission case 7 side by expansion / contraction links 17 and 18 so that the front part can freely move up and down. In each of the ground leveling floats 10, 11, and 11, the left and right outer side surfaces or one side surface section is constricted inward from the front to the rear in plan view, and the rear is narrowed, and one of the narrowed portions is narrowed. The upper surface of the outer side portion is recessed downward to reduce the thickness.

They are arranged so that they do not interfere with each other. Further, the rear pivotal support portion D of the ground leveling floats 10, 11 and 11 (the pivotal attachment portion by the shaft 16) is located slightly below the front of the rotation center e of the rotating case 14 in a side view, and approaches the trajectory a. It is provided on the side and is located near the center of rotation E.

Needless to say, the shaft 16 may be provided with an insertion hole in the arm swingable by the operation lever so that the operation lever can be moved up and down to some extent to adjust the seedling planting depth.
Next, the operation of the above example will be described. When each part is transmission-rotated while propelling the tow vehicle body 1, each leveling float 10,
11, the soil surface is leveled, and as the rotating case 14 rotates, the seedling planting tools 15, 15 are actuated and the seedling planting claw 15a.
Draws the locus of transplantation, splits and engages seedlings from the seedling mounting table 9 one by one, and plunges below the soil surface, and the seedling pusher 15b pushes down the engaged seedlings to open them, and plant seedlings one after another. .

り、確実な植付けができる。At this time, the ground leveling floats 10 and 11 move up and down on the front side due to the unevenness of the soil surface, but since the rear pivotal support D is located near the center of rotation of the rotating case 14,
The rotating case 14 does not accidentally collide with the upper surfaces of the ground leveling floats 10 and 11. Further, since the pivotal support D is located on the side closer to the transplanting locus A, the variation of the seedling planting depth is reduced and reliable planting can be performed.

なえる。In particular, since the shaft 16 for pivotally supporting the ground leveling float 10 is provided on the rear side of the machine body of the seedling mounting table 9 and on the front side of the machine body of the drive shaft 13, the shaft 16 is inevitably formed.
Is close to the drive shaft 13, and even if the front part of the ground leveling float 10 moves up and down, it is less likely to interfere with the rotating case 14, and as a result, the drive shaft 13 of the rotating case 14 is moved to a lower position than before. Since the setting can be made and the locus of planting can be made small, a small and lightweight seedling planting machine can be obtained. However, the shaft 16 is inevitably near the seedling planting position, and even if the front part of the leveling float 10 moves up and down, it does not affect the planting depth of the seedling so much that the proper seedling planting work is performed. Can be done.
