【発明の詳細な説明】 〔産業上の利用分野〕 本発明は乗用型田植機における整地構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a leveling structure for a riding type rice transplanter.

〔従来の技術〕[Conventional technology]

乗用型田植機では機体の後部に苗植付装置が連結されて
いるので、走行用の車輪の跡が苗の植付けに影響を及ぼ
す場合がある。そこで、この車輪の跡を消す整地部材を
車輪の後方に昇降自在に配置し、この整地部材をバネ等
により接地側に付勢するか、又は整地部材の自重により
田面に接地させていく構造が提案されている。
In the riding type rice transplanter, since the seedling planting device is connected to the rear part of the machine body, the traces of the wheels for traveling may affect the seedling planting. Therefore, there is a structure in which a ground leveling member that erases the traces of the wheel is vertically arranged behind the wheel, and the ground leveling member is biased toward the grounding side by a spring or the like, or is grounded on the rice field by the weight of the ground leveling member. Proposed.

このように整地部材を支持すると、植付走行中において
田面の凹凸に沿って整地部材が上下動して、田面の表面
が的確に整地されて行くのである。
When the soil leveling member is supported in this manner, the soil leveling member moves up and down along the unevenness of the paddy field during traveling with planting, so that the surface of the paddy field is accurately leveled.

〔発明が解決しようとする課題〕[Problems to be Solved by the Invention]

乗用型田植機では1回の植付行程が終了して枕地に達す
ると、苗植付装置を持ち上げるか又は苗植付装置を持ち
上げないで植付アームを田面より上方で停止させた状態
で、180°旋回して次の植付行程に入って行く。従っ

地部材による整地作用が期待できる。
When the riding type rice transplanter completes one planting process and reaches the headland, either lift the seedling planting device or leave the planting arm above the rice field without raising the seedling planting device. , Turn 180 ° and enter the next planting process. Therefore, in the above-mentioned structure, the leveling action of the leveling member can be expected even when the headland is turned.

しかしながら、枕地での乗用型田植機は前輪の向きを大
きく変えて小半径で旋回する為に、枕地は非常に荒れ

十分に枕地を整地しなければならず、その作業が煩わし
いものとなる。
However, since the riding type rice transplanter in the headland changes the direction of the front wheels and turns in a small radius, the headland becomes very rough. Since the weight of the soil leveling member or the biasing force to the ground contact side is set for the relatively flat part in the center of the field, the leveling performed at the time of turning on the headland cannot be said to be sufficient. Therefore, when planting seedlings on the headland after this,
The headland must be leveled sufficiently, which makes the work troublesome.

本発明は、枕地での苗の植付作業の負担軽減を図ること
を目的としている。
An object of the present invention is to reduce the burden of planting work of seedlings on a headland.

The feature of the present invention is that the seedling planting device is connected to the rear part of the machine body so that it can be moved up and down by an actuator, the ground leveling member is arranged rearward of the traveling wheel, and the ground leveling member is biased to the ground side. In the riding-type rice transplanter equipped with a biasing mechanism, the means for strengthening the biasing force of the biasing mechanism is provided in association with the disengagement operation of the planting clutch. In a riding-type rice transplanter, which is connected to the rear part of the machine body so that it can be moved up and down freely, and is equipped with a ground leveling member that can be moved up and down behind the traveling wheels, in conjunction with the disengagement operation of the planting clutch It is equipped with a restraining means for preventing the ascending motion beyond the upper part of the vehicle. Furthermore, the seedling planting device is connected to the rear part of the machine body so that it can be moved up and down through the first elevating mechanism, and the rear part of the wheel for traveling is connected. Place the ground leveling members The riding type rice transplanter connected to the rear part of the airframe through the second lifting mechanism is provided with a restraining means for interlocking with the disengagement operation of the planting clutch to prevent the raising operation of the ground leveling member beyond a predetermined position. At the same time, the seedling planting device and the ground leveling member are interlockingly connected to each other so that the ground leveling member can be integrally lifted with the seedling planting device, and the operation and effect thereof are as follows.

〔作用〕[Action]

乗用型田植機では1回の植付行程が終了し枕地に達する
と、植付クラッチを切り操作して苗植付装置を停止させ

And if the configuration as described in the preceding paragraph is performed, leveling at the time of turning on the headland is sufficiently performed, and if the connection mechanism is in the connected state, if the seedling planting device is lifted upward, the leveling member also interlocks with this. Since it is lifted up, the ground leveling member does not get in the way when traveling on the road.

〔発明の効果〕〔The invention's effect〕

以上のように枕地での旋回時に整地を十分に行えるよう

As described above, it becomes possible to perform sufficient leveling when turning in a headland, and when planting seedlings in the headland later, it is not necessary to perform leveling, and the work load should be reduced. I was able to. Moreover, since the disengagement operation of the planted clutch is always performed before turning in the headland, it is rare that the operation is forgotten.

そして、路上走行時等に整地部材が邪魔になるようなこ
ともない。
Further, the ground leveling member does not become an obstacle when traveling on the road.
