Problems to be Solved by the Invention Pitching mechanism that corrects changes in ground posture due to the lifting and lowering of a seedling planting device attached to the running vehicle body via a link lifting mechanism, and a rolling mechanism that can roll relative to the lifting mechanism. In a lifting device having a lifting section, if the raised seedling planting device is rolled in a suspended state, the weight balance changes due to rolling, which may impede the running of the vehicle, and may also cause malfunction of the rolling section. For this reason, if a single rolling stop mechanism is provided, the stop mechanism must be operated each time the seedling planting device is raised and lowered, which complicates handling operations during seedling planting work.

When the traveling vehicle body (1) is moved forward, the float (35) follows the soil surface and is attached to the planting device (3) by the support shaft (31).
The seedlings are planted by operating the seedling rod (32) that receives the seedlings from the seedling stand (30) without rolling the seedlings, and when the switching valve is operated to the upward side of the planting device (3), the hydraulic cylinder By protruding the piston part of (21),
The frame body (25) and seedling planting are sealed by upward rotation of the upper link (20) and lower link (17) via the arm part (19)! (3) rises, but at the same time the piston part of the cylinder (28) moves to the entry side, causing the left and right locking bodies (5) (5) to move through the coupling member (2?) and support pin (2B). ) is rotated downward and when the left and right locking bodies (t5) (15) come into contact with the stopper (3B), the support pin (2B) moves forward in the elongated hole (22), so the pin By rotating the frame body (25) and the planting device (3) using the section (20) as a fulcrum, the ground posture of the planting device (3) is corrected, and conversely, when the switching valve is operated to the downward side,
The support bin (2B) is moved to the front end of the long hole (22) by the weight of the planting device (3) to restore the ground posture of the planting device (3), and hydraulic pressure is applied via the link mechanism (2). It descends while pressing the piston part of the cylinder (21), and at this time, the left and right locking bodies (5) (5) engage the stopper (3B) because the hydraulic cylinder (21) is in an inactive state.
) does not act, and rolling of the planting device (3) is therefore possible.
