操作も簡明化できる。Functions and Effects of the Invention During work traveling, the float provided at the bottom of the working device (2) of the traveling vehicle body (1) slides on the soil surface.
A float detects the soil condition, and the movement of the float activates a pitching detection device (3) that raises and lowers the working device (2), and a rolling detecting device (4) that tilts the working device (2) from side to side. However, when adjusting the detection sensitivity of these rain detection devices (3) and (4), operate the operating mechanism (5).When the soil surface is soft, the operating mechanism When (5) is adjusted to the soft side, both detection devices M (3) and (4) operate sensitively, and when the soil topsoil surface is hard, adjusting the operating mechanism (5) to the hard side causes the detection devices M (3) and (4) to operate sensitively. The rain detection devices (3) and (4) operate in an insensitive manner, allowing stable work to be carried out by always maintaining a working posture at a constant depth regardless of whether the soil surface is soft or hard. Detection device (3) and rolling detection device (
4) can be adjusted to the same degree, the pitching operation and the rolling operation can be balanced, and the sensitivity adjustment operation can be simplified.

22) and the center float (23) while sliding on the ground, the seedlings loaded in the seedling tank (20) which is moved from side to side by the gear case (18) are separated from the seedling take-out port, and the seedlings are separated from the left and right by the seedling cutting device (21). Float (22), (22) and the central flow) Transplant into the soil leveled by (23). Due to the unevenness of the tiller in the paddy field during the planting operation, the pressure applied to the bottom of the central float (23) changes, and this pressure causes the central float (23) to move up and down, causing the central flow (23) to change. A hydraulic device (
The piston (14) operates, the coupling device (15) moves up and down, and the working device (2) rises or descends depending on the unevenness of the tiller, and the working device (2) always moves against the unevenness of the tiller. ) is maintained at an appropriate vertical position, and at the same time, the piston of the hydraulic system (30) that is linked to the proximity sensor (32) of the rolling detection device (4), which is activated by the tilting of the seedling tank (20), is activated to prevent rolling. The post (17) rotates left and right, the working device (2) rotates left or right, and the working device (2)
is always maintained horizontally, but a sensitivity lever (38) adjusts the detection sensitivity of the pitching detection device (3) and rolling detection device (4) in advance depending on the condition of the topsoil surface.
For example, when the topsoil surface is soft, the detection sensitivity of the rain detection devices (3) and (4) becomes more sensitive. Both rain detection devices M (3) and (4) sensitively detect the soil condition and maintain the rain detection devices (3) and (4) in the proper positions vertically and horizontally to ensure stable planting depth and insertion.
