The seedling platform 9 of the seedling planting device 10 is supported so as to be able to reciprocate freely on a laterally extending pedestal 12 fixed below the seedling platform 9, and the seedling platform 9 is supported at the rear of the body 1. A transmission case 13 containing a reciprocating mechanism is provided at a location opposite to the reciprocating mechanism, and actuating arms are provided at both ends of the reciprocating shaft 14 protruding from the case 13 to protrude forward from both outsides of the seedling platform 9. 15 is connected to the reciprocating shaft 14 that is used for the operation of the reciprocating mechanism.
By reciprocating, the seedling stand 9 is caused to reciprocate from side to side on the pedestal 12 via the arm 15.

The bonnet is located near the reciprocating locus of the seedling platform 9 and higher than the lubricated parts such as the connecting rotation part between the lifting arm 5 and the interlocking rod 6, that is, in this embodiment, at the rear upper part of the machine body 1. Oil tank 1 inside of 16
A switching arm 7 is provided, which connects the oil pipe 20 facing the oiled part to the tank 17, and cuts off the supply of oil to the oiled part from the oil tank 17 to the oiled part. The switching arm 18 of the oil supply valve 19 is connected to the actuating arm 15 of the seedling stand 9 via a connecting member 21 such as a wire, so that the reciprocation of the seedling stand 9 is provided. In conjunction with the movement, the switching arm 18 is operated via the connecting member 21 to supply or cut off oil from the oil supply valve 19 to the oiled portion via the oil pipe 20.

As the oil supply valve 19, for example, a rotary valve or a pinch valve is used.
The oil tank 17 is installed at a higher position than the oiled part, and the oil tank 17 is designed to supply oil to the oiled part by a head difference.

Further, in the embodiment described above, the tip of the oil pipe 20 is made to face the connecting rotating part between the lifting arm 5 and the connecting rod 6, and the rotating part is to be supplied with oil from the tank 17 via the oil pipe 20. The oil pipe 20 faces the rotating part of the arm 5 connected to the body 1, the sliding contact part between the seedling stand 9 and the pedestal 12, and other parts to be oiled, so that these parts can be oiled. You may choose to do so.
