DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below. First, the overall configuration of the seeder will be described. In this seeding machine, a first conveyor 1 for continuous transfer, a seeding conveyor 2 capable of switching between continuous transfer and intermittent transfer, and a second conveyor 3 for continuous transfer are sequentially installed from the transfer side. The respective seedling boxes 4 are transferred by successively taking over the respective conveyors 1, 2, and 3. Then, the bed soil supply device 5, the pressure suppression and leveling device 6 are sequentially installed on the first conveyor 1, the point seeding type seeding device 7 is installed on the seeding conveyor 2, and the soil cover supplying device 8 is installed on the second conveyor 3.
A mist irrigation device 9 is installed. As a result, the seedling box 4 placed on the starting end of the first conveyor 1 on the transfer side is ...
First, the soil is packed and crushed and leveled, then taken over by the seeding conveyor 2 and seeded there, and the second
It is taken over by the conveyer 3, where it is covered with soil and watered to complete the seeding work.

Next, each device of the seeder will be described in detail. Reference numeral 1 is a first conveyor, and pulleys 1d, 1d, 1 are attached to pulley shafts 1b, 1c supported by frames 1a, 1a.
e, 1e are attached respectively, and between the pulleys 1d
The transfer belts 1f and 1f are wound around -1e and 1d-1e, and one pulley shaft 1b is interlocked with the transfer motor M1. As a result, the seedling boxes placed on the transfer belts 1f and 1f between the frames 1a and 1a are transferred to the transfer motor M.
When 1 rotates, it is continuously transferred in the belt moving direction, and when it stops, transfer is stopped.

Reference numeral 2 is a seeding conveyor, which is a frame 2a, 2a.
The roller shafts 2b, 2c supported by the rollers 2d, 2
e are attached respectively, and between the rollers 2d-2e
The transfer belt 2f is wrapped around the. And, on one roller shaft 2b, that is, the drive shaft of the seeding conveyor 2,
A continuous drive mechanism by a continuous transfer drive motor M2 and an intermittent drive mechanism by an intermittent transfer air-cylinder C1 are interlockingly connected. Specifically, first, the roller shaft 2
A sprocket 10 for continuous transfer is attached to b through a one-way clutch 10a on the continuous drive side, and a continuous drive sprocket 12a attached to the sprocket 10 and the drive shaft 12 of the drive motor M2 so as to rotate integrally. A chain 13 is hung between and to form a continuous drive mechanism. Thereby, the continuous drive side one-way clutch 10a
With the boundary as the boundary, the continuous drive side (drive motor M2 side) and the roller
With respect to the shaft 2b side, when the continuous drive side becomes the drive side, the power is transmitted from the continuous drive side to the roller shaft 2b, and when the roller shaft 2b side becomes the drive side, the continuous drive side from the roller shaft 2b. Not transmitted to. That is, when the drive motor M2 is driven and rotated, the continuous rotation of the drive motor M2 is rotated.
The seeding conveyor 2 is continuously transferred by being transmitted to the lathe shaft 2b. When the drive motor M2 is not driven, the drive motor M2 is not forcibly rotated even if the roller shaft 2b side is intermittently driven by the intermittent drive mechanism.

A sprocket 11 for intermittent transfer is attached to the roller shaft 2b.
1 and the intermittent drive sprocket 15 attached to the intermittent drive shaft 14 so as to rotate integrally with each other, and the chain 16 is hooked on the intermittent drive shaft 14. Further, the free end side of the intermittent drive sprocket 15 has a piston C1a of an air-cylinder C1 for intermittent drive. Arm 18a to be connected
The arm cylinder 18 to which the base portion of is fixed is attached via an intermittent drive side one-way clutch 17 to form an intermittent drive mechanism. When the piston C1a of the air cylinder C1 projects and the arm cylinder 18 rotates by the intermittent drive side one-way clutch 17, the intermittent drive shaft 14 is transmitted so as to rotate integrally, and the piston C1a of the air cylinder C1 retracts. When the arm cylinder 18 rotates in the reverse direction, the intermittent drive shaft 1
No drive for 4 and no transmission. As a result, when the piston C1a of the air-cylinder C1 is actuated by a constant stroke, protrusion, and retraction at a predetermined timing, the intermittent drive shaft 1
4 rotates intermittently by a constant angle, the roller shaft 2b rotates intermittently, and the seeding conveyor 2 is in an intermittent transfer state. Also, with the intermittent drive side one-way clutch 17 as a boundary, between the intermittent drive side (air-cylinder C1 side) and the roller shaft 2b side, when the intermittent drive side becomes the drive side, the intermittent drive side rolls. -Intermittent rotation is transmitted to the shaft 2b as described above, the intermittent rotation is transmitted to the roller shaft 2b, and even if the air-cylinder C1 does not operate and the roller shaft 2b side is continuously driven by the continuous drive mechanism, it is intermittent. The continuous rotation is not transmitted from the drive side one-way clutch 17 to the air-cylinder C1 side.

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.

The transfer belt 3 is attached to the pulleys 3d-3e and 3d-3e.
f and 3f are wound around, and one pulley shaft 3b is interlockingly connected with the transfer motor M3. As a result, the frame 3
The seedling boxes 4 placed on the transfer belts 3f and 3f between the points a and 3a are continuously transferred in the belt moving direction when the transfer motor M3 rotates, and stopped when the transfer motor M3 stops.

The seedling box 4 has a length and width of 3 which is generally used.

At the time of vegetable / flower seed sowing work (when the seeding conveyor 2 in which the point seeding type seeding device 7 is installed) is incorporated, first, the changeover switch SW is switched to the vegetable / flower seed sowing work position. Then, the first conveyor 1, the seeding conveyor 2 continuously transfer the seedling boxes 4 ... Until the seeding position of the point-seeding type seeding device 7 (the seeding hole forming position), and then the point-seeding type seeding device 7 operates and is intermittent. It is switched to the transfer state, and when seeding is completed, it is again in the continuous transfer state. 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. The second conveyor 3 is always in a continuous transfer state. Further, in the rod-shaped / misty irrigation device 9, the pump P1 is operated while the pump P2 is stopped, and the misty irrigation state is established.

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.

Further, in this seeding machine, in the drive mechanism of the seeding conveyor 2, between the continuous drive mechanism and the drive shaft 2b, the continuous drive side which is transmitted to the drive shaft 2b when driven from the continuous drive mechanism side is one direction. 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.
