あける等の損傷が生起するおそれがあった。Conventionally, in a seedling planting device configured to rotate the seedling planting claw using a crank mechanism, when the driven arm swings, the tip of the swinging arm falls below the lower end of the driven arm support. When the upper surface of the float rises due to deflection of the float, the swinging tip of the driven arm may come into contact with the float, causing damage such as puncturing the float.

んとするものである。In this invention, when the driven arm swings, the swinging tip is configured so that it stops at a position above the lower end position of the driven arm support arm, so that the swinging tip of the driven arm comes into contact with the top surface of the float. It is an object of the present invention to provide a seedling planting device for a rice transplanter that can reduce damage to the float by preventing the floating from occurring.

る。If we explain the embodiment of this invention in detail based on the drawings, A shows the whole walk-behind rice transplanter, but it can also be applied to a riding-type rice transplanter in the same way, and a float 1 is attached at the bottom. An engine 3 is mounted on the front of the main body 2 of the rice transplanter to be installed, an operating case 4 that receives input from the engine 3 is placed behind it, a seedling planting section is placed on the rear of the machine, and a seedling mat is placed behind it. Low front and high rear seedling stand 5 and no-endoru 6
There are wheels 7 on both sides of the rice transplanter main body 2.
A seedling planting device 8 is provided in front of the seedling platform 5.
同苗植付装置８は次のように構成されている。The seedling planting device 8 is configured as follows.

出せしめている。That is, the tip of the crank arm 12 connected to the planting drive shaft 11 is connected to the midway part of the planting arm 10 which has the seedling planting claw 9 at the tip, and the driven arm 13 is connected to the base end of the planting arm 10. The tip of the driven arm 13 is pivotally connected, and the base end of the driven arm 13 is pivotally connected to a driven arm supporting arm piece 15 connected below the planting case 14, and the lower end 1 of the driven arm supporting arm piece 15 is
6 projects further downward from the pivot point at the base end of the driven arm 13.
Ｌは、従動アーム支持腕片１５の下端位置を示す。L indicates the lower end position of the driven arm support arm piece 15.

しか揺動しないように構成されている。Further, the driven arm 13 rotates within a certain range around the pivot portion 13-1 at the base end, but the swinging tip of the driven arm 13 1
3-2 is configured so that it can only swing at a certain upper position 1 from the height of the pivot portion 13-1.
すなわち、従動アーム支持腕片１５の下端を下方に伸延
しその下端の位置りよりも上方位置で、揺動先端部１３
−２の揺動が止するものである。That is, the lower end of the driven arm support arm piece 15 is extended downward, and the swinging tip portion 13 is positioned above the lower end position.
-2 stops swinging.

なる。In this invention, in the seedling planting work, the planting drive shaft 11
, the crank arm 12 is cranked to rotate the planting arm 10 and perform the planting work of the seedling planting claw 9. At this time, the driven arm 13 is attached to the pivot at the base end. It will swing only within a certain range around the portion 13-1.
すなわち、従動アーム１３の揺動範囲は、下限がほぼ枢
着部１３−１と同じ高さの水平位置であり、上限が下限

よりも上方に位置していることになる。That is, in the swing range of the driven arm 13, the lower limit is a horizontal position approximately at the same height as the pivot joint 13-1, and the upper limit is a position slightly above the lower limit position. It is always located above the extended lower end of the driven arm support arm piece 15.

る。Therefore, even if a portion of the float 1 rises due to bending or the like, the upper surface is received by the lower end of the driven arm support arm piece 15 and is prevented from rising above the L position, thus preventing the driven arm 13 from swinging. At the lower limit position during movement, the swinging tip 13-2 of the arm 13 never comes into contact with the top surface of the float, which prevents damage to the float or the driven arm due to contact between the driven arm 13 and the float 1. It is intended to prevent

損傷を防止できる効果がある。According to this invention, since the swinging tip of the driven arm is located above the pivot point at the base end of the driven arm, the bulge on the top surface of the float due to deflection of the float is absorbed by the lower end of the driven arm support arm. Therefore, there is no contact with the swinging tip of the driven arm, and there is an effect that damage caused by contact with the float or the driven arm can be prevented.
