Description

【発明の詳細な説明】 本発明は、苗植付装置を駆動装置により昇降操作自在に
車体に取付け、前記苗植付装置と駆動装置の相対変位を
許容するための弾性連結部を設けた田植機に関する。
DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rice planting device in which a seedling planting device is attached to a vehicle body so that it can be raised and lowered by a drive device, and an elastic connection portion is provided to allow relative displacement between the seedling planting device and the drive device. Regarding machines.

上記田植機において、従来、苗植付装置を極力低い位置
まで下降できるようにして、浅い圃場で十分な植付深さ
を得られるようにしていた。
Conventionally, in the above-mentioned rice transplanter, the seedling planting device has been made to be able to be lowered to a position as low as possible, so that sufficient planting depth can be obtained in shallow fields.

よって、苗植装置に衝撃が加わって、弾性連結部が下降

破損するという欠点があった。
Therefore, when the seedling planting device is lowered and traveling or performing inspection work, shocks are applied to the seedling planting device due to vibrations from traveling, careless operation, etc., and the elastic connection part is displaced downward. In this case, there is a drawback that the seedling planting device comes into contact with the road surface and the seedling planting claws etc. are damaged.

本発明は、上記欠点に鑑み、苗植付装置の1時限度を低

うにすることを目的とする。
In view of the above drawbacks, the present invention aims to prevent the seedling planting device from coming into contact with the road surface, etc., while setting the one hour limit of the seedling planting device low.

The characteristic configuration of the rice transplanter according to the present invention is such that the seedling planting device comes into contact with the road surface due to the descent due to deformation of the elastic connecting portion below the lower end of the normal lifting range of the seedling planting device by the drive device. The reason is that a stopper is provided to prevent this from happening, and its effects are as follows.

In other words, the lowermost position of the seedling planting device can be set as low as in the past, and sufficient seedlings can be planted in shallow fields, due to the action of the stopper that prevents the seedling planting device from descending due to deformation within the elastic connection part. Even if it is possible to obtain the desired depth, the lowering of the seedling planting device is prevented, which prevents the seedling planting device from coming into contact with the ground and deforming or damaging the float or seedling planting claw. The stopper is designed to work below the lower end of the normal lifting range of the planting device, so it only works when there is a risk that the seedling planting device will come into contact with the ground. It was possible to reliably prevent the juxtaposition of seedlings, which would result in improper planting of seedlings due to incorrect operation.
