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.

性連結部が下降変位した場合、苗植装置が路面に
接触して苗植付爪等が破損するという欠点があつ
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. Therefore, when the seedling planting device is lowered and traveling or during inspection work, shocks may be applied to the seedling planting device due to vibrations from traveling or careless operation, causing the elastic connection to become damaged. When the part is displaced downward, 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、苗植付装置の下降
限度を低く設定しながらも、苗植付装置が路面等
に接触しないようにすることを目的とする。 In view of the above-mentioned drawbacks, the present invention aims to prevent the seedling planting device from coming into contact with the road surface, etc., while setting the lowering limit of the seedling planting device low.

起因して、前記苗植付装置が路面に接触すること

用効果は次の通りである。 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 for this is that a stopper is provided to prevent this from happening, and its effects are as follows.
つまり、苗植付装置が弾性連結部の変形によつ
て下降することを阻止するストツパーの作用によ
り、従来と同様に苗植付装置の最下降位置を低く

害を確実に防止することができた。 In other words, due to the action of the stopper that prevents the seedling planting device from descending due to deformation of the elastic connection part, the lowest position of the seedling planting device can be set low as in the past, and sufficient seedlings can be planted in shallow fields. Even if it is possible to obtain the planting 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. Since the stopper is designed to work below the lower end of the normal lifting range of the seedling planting device, it only works when there is a risk that the seedling planting device will come into contact with the ground, for example, during normal seedling planting work. It was possible to reliably prevent complications such as failure of seedlings to be planted due to the stopper acting incorrectly.
次に、本発明の構成の実施例を説明する。 Next, an example of the configuration of the present invention will be described.
