るためのものである。By the way, the intermittent transfer of the seeding conveyor 2 is as follows.
The pot p of the seedling-growing pot P ... Since it is necessary to intermittently and accurately transfer one row at a time or several rows at a time,
When the lathe shaft 2b is rotated by a predetermined amount, it must be stopped immediately, and when the seeding operation is completed, it must be immediately rotated again. Therefore, in the drive mechanism of the seeding conveyor 2,
Since the sprocket 10 for continuous transfer is not attached to the roller shaft 2b so as to rotate integrally therewith, but the continuous drive side one-way clutch 10a is interposed and attached,
The following effects are brought about. That is, air-cylinder C
When 1 operates and the roller shaft 2b is intermittently rotationally driven from the intermittent drive mechanism side, the rotation is not transmitted from the continuous drive side one-way clutch 10a to the drive motor M2 side,
The motor M2 is never forced to rotate. As a result, the inertial weight of the roller shaft 2b can be kept small during intermittent driving. Therefore, air-cylinder C
It is possible to suppress inertial rotation on the side of the roller shaft 2b after the piston C1a of No. 1 protrudes by a predetermined stroke, and
The load when the piston C1a of the air-cylinder C1 is projected can be reduced, and accurate and quick intermittent transfer can be performed by a predetermined transfer amount. As a result, the seeds are more accurately seeded in the center of each pot p, so that the seeding accuracy is improved, and the seeding work speed is also increased to improve the seeding efficiency. In addition, BL is a brake device, which is a sprocket 11 for intermittent transfer and which has a rotating disk 11a sandwiched between the rollers to exert a braking action on the roller shaft 2b. -To further suppress the inertial rotation of the ra shaft 2b.

ラが生じることはない。The seedling raising seeding machine of the present invention is provided with a continuous drive mechanism for continuously transferring the seedling raising pot P on the drive shaft 2b of the seeding conveyer 2 and the seedling raising pot P.
Pot p ... Since an intermittent drive mechanism for intermittently transferring one row or several rows is provided, first of all, the first conveyor 1, the seeding conveyor 2, the seedling boxes 4, ... After continuous transfer, the point-seeding type seeding device 7 starts to operate and the seeding conveyor 2 is switched to the intermittent transfer state, and when the seeding is completed, it operates again to the continuous transfer state. Then, when the seeding conveyor 2 is in the intermittent transfer state, the transfer of the first conveyor 1 is stopped, and when the seeding conveyor 2 is in the continuous transfer state, the first conveyor 1 is in the continuous transfer state. In addition, the second conveyor 3 is always in a continuous transfer state. In this way, the whole conveyor 1, 2, 3 does not operate intermittently, but only the seeding conveyor 2 that requires intermittent transfer is operated only during the seeding operation, and the soil covering device is continuously provided on the lower side of the seeding device 7. Since the 8 and the conveyor 3 of the irrigation system 9 are configured so as to be continuously transferred at all times, uneven soil coverage and uneven irrigation do not occur.

The clutch 10a is interposed, and the intermittent drive side one-way clutch 17 that is transmitted to the drive shaft 2b when driven from the intermittent drive mechanism side is interposed between the intermittent drive mechanism and the drive shaft 2b. When the drive shaft 2b is intermittently rotationally driven from the intermittent drive mechanism side, the rotation is not transmitted from the continuous drive side one-way clutch 10a to the continuous drive mechanism side. As a result, the inertial weight at the time of intermittent driving can be kept small, and accurate and rapid intermittent transfer can be performed by a predetermined transfer amount. As a result, seeding is performed more accurately in the center of each pot p, so that the seeding accuracy is improved, and the seeding work speed is increased.
The seeds are also improved and the seeding efficiency is also improved.
