る田植機に関する。[Detailed Description of the Invention] The present invention is characterized in that a planting device having a seedling stand that can be moved in a reciprocating manner in the lateral direction is supported on this machine so as to be able to swing left and right around the front and back axis. Between the seedling rest and the seedling rest, when the seedling rest moves laterally from the center position of the lateral movement path, a pulling force is applied to the part of the seedling rest on the side that has moved laterally. This relates to a rice transplanter that has a pair of left and right springs tensioned.

のせ台の横移動動力が大となる不都合があつた。 This rice transplanter has the advantage that the planting device can be maintained in a horizontal position by the pulling force of the spring pair, regardless of the movement of the center of gravity in the left and right directions due to the lateral movement of the seedling table. Conventionally, the left and right springs are tensioned so that they are parallel to each other, so as the seedling stand moves laterally, both springs elastically deform in the same way, and only the one on the side that moves laterally deforms. Instead, the other one exerts a similar pulling force, and the entire seedling stand is pulled up, and as a result,
In order to pull up the side of the seedling stand on the side that moves sideways and prevent the overall weight balance from becoming unbalanced, it is necessary to use an unreasonably strong spring, which inconveniently increases the horizontal movement force of the side of the seedling stand. It was hot.
本考案は、前記スプリング対に対する配置改良
のみをもつて、かかる不都合を合理的に解消しよ
うとする点に目的を有する。 An object of the present invention is to rationally eliminate such disadvantages only by improving the arrangement of the spring pair.

とする。 The rice transplanter according to the present invention is as follows:
The spring pairs are arranged so that when the seedling stand is located at the end of the lateral movement path, the one on the lateral movement side is in a pulling action state, and the other springs are in a free state or a state close to it. It is characterized by:
即ち、苗のせ台が横移動経路の端部に位置した
とき、その横移動側のスプリングが引上げ作用

苗のせ台部分を引上げるに足りるだけの比較的、
弱いスプリングを用い乍も、苗のせ台の横移動に
かかわらず、植付装置を水平姿勢に安定維持し、
バランス修正を効果的に行なえるに至つた。 In other words, when the seedling stand is located at the end of the lateral movement path, the spring on the side of the lateral movement acts to pull it up, and the other spring does not act to pull it up, or even if it does, it only does so slightly, so it is substantially In addition, only the side of the seedling platform that can be moved laterally can be pulled up without having to pull up the entire seedling platform. Therefore, both springs are made to act effectively only to pull up the side seedling stand part on the lateral movement side, and the relatively large amount of force necessary to pull up the side seedling stand part on the lateral movement side is
Even though a weak spring is used, the planting device can be stably maintained in a horizontal position regardless of the horizontal movement of the seedling stand.
We were able to effectively correct the balance.
