。DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of planting seedlings by constantly maintaining the attitude of the device toward the mud surface, regardless of the left and right tilting of the traveling body having a pair of left and right traveling wheels and a steering bundle. When planting seedlings at the rear of the traveling aircraft, the device is moved along the longitudinal axis to prevent variations in depth when planting in the left and right directions, which is caused by the device tilting along with the aircraft. In addition to being pivotally connected around the core, soil leveling floats are arranged below the device for planting seedlings, at the center position between the left and right wheels, and at the left and right inner and outer positions thereof. The purpose of this walk-behind rice transplanter is to make it possible to easily maneuver the machine during rice planting work in fields where the tiller is generally tilted from side to side, such as on sloping land.
即ち、傾斜地のように、その耕盤面が左右に傾斜してい
る圃場での田植作業時には、走行機体が左右に傾動し、
重心が移動するため、走行機体は傾斜下方に蛇行し易い
力を受け、この蛇行力に抗して直進走行させるだけの犬
なる操作力をバンドルに加え続けなければならないため
、非常に操縦しにくい。In other words, during rice planting work in a field where the plowing surface is tilted left and right, such as on a slope, the traveling machine tilts left and right.
As the center of gravity shifts, the traveling aircraft receives a force that tends to cause it to meander downwards, making it extremely difficult to maneuver as it is necessary to keep applying a force to the bundle to resist this meandering force and keep it moving straight. .
本発明は、上述のような圃場での操縦上の問題点を、フ
ロートの簡単な改良をもって解消せんとしたものであっ
て、冒記したものにおいて、中央の整地用フロートを走
行機体側に取付けろとともに、両側部のフロートを苗植
付は装置側に取付けであることを特徴とする。The present invention aims to solve the above-mentioned operational problems in the field by simply improving the float. It is characterized in that the floats on both sides are attached to the device side for planting seedlings.
これによって、耕盤面の傾斜に伴なって走行機体が左右
に傾動した際、走行機体には傾斜方向下方への蛇行力を
受けるが、この蛇行力を、走行機体と一諸に傾動する中

前記の蛇行力に抗して直進走行させるだけの犬なる操作
力をバンドルに加え続ける必要がなく、傾斜地などでの
機体操縦を楽に行なうことができろ。As a result, when the traveling body tilts left and right due to the slope of the plowing surface, the traveling body receives a meandering force downward in the direction of inclination, but this meandering force is absorbed by the central float, which tilts together with the traveling body. This can be offset or reduced by the increase in ground resistance at the part of the bundle that enters the mud, so as mentioned above, it is necessary to continue applying a force to the bundle that is sufficient to resist the meandering force and make it run straight. The aircraft should be able to maneuver easily on slopes and other terrain.

に達成し得るに至った。However, as mentioned above, since only the central ground leveling float, which is located at the point where the vertical fluctuation is the smallest when the aircraft tilts from side to side, is attached to the traveling aircraft side, even when the traveling aircraft tilts from side to side, There is very little variation in the depth of planting in this direction, and by configuring the seedling planting device so that it can swing freely around the longitudinal axis, it has become possible to reliably achieve the intended purpose.
