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, the first conveyor 1a and the second conveyor 1b for continuous transfer, the seeding conveyor 2 capable of switching between continuous transfer and intermittent transfer, and the third conveyor 3 for continuous transfer are sequentially transferred from the transfer side. They are installed in series and each conveyor 1
The seedling boxes 4 are transferred by successively taking over a, 1b, 2, and 3. And the first conveyor 1a
A bed soil supply device 5 is installed on the top, a crushing and leveling device 6 is installed on the second conveyor 1b in this order, a point seeding seeding device 7a is installed on the seeding conveyor 2, and a dispersal seeding device 7b is installed on the third conveyor 3. A cover soil supplying device 8 and an irrigation device 9 for switching between rod-like irrigation and mist-like irrigation are installed.

Next, each device of the seeder will be described in detail. In the first conveyor 1a, pulleys 1e and 1f are attached to pulley shafts 1c and 1d supported by a frame, and a transfer belt 1g is wound between the pulleys 1e and 1f. One pulley shaft 1c is driven and rotated by the transfer motor M1. As a result, the seedling box 4 placed on the transfer belt 1g between the frames is continuously transferred at the speed V1 in the belt moving direction when the transfer motor M1 is rotated, and is transferred when it is stopped. Be stopped.

In the second conveyor 1b, a conveyor belt 1i is wound around a conveyor roll shaft 1h supported by a frame, and a sprocket 1j provided on the conveyor roll shaft 1h ... and the pulley shaft 1c. The chain 1m is wound around the sprocket 1k provided on the above, and is driven and rotated by the transfer motor M1. And sprocket 1
The number of teeth of j ... is smaller than the number of teeth of the sprocket 1k, that is, the speed of rotation is increased between the sprockets 1k, 1j ..., and the seedlings placed on the second conveyor 1b. The box 4 is transferred at a speed V2 faster than the moving speed V1 of the seedling box 4 placed on the first conveyor 1a.

The seeding conveyor 2 has rollers 2d and 2e mounted on roller shafts 2b and 2c supported by frames 2a and 2a.
Are respectively attached, and the transfer belt 2f is wound around the rollers-2d and 2e. On one of the roller shafts 2b, that is, the drive shaft of the seeding conveyor 2, a continuous drive mechanism using a drive motor M2 for continuous transfer and an intermittent drive mechanism using an air cylinder C1 for intermittent transfer. Are linked together. Specifically, first, the roller shaft 2b
A sprocket 10 for continuous transfer is attached to the sprocket 10 via a continuous drive side one-way clutch 10a, 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 the two to form a continuous drive mechanism. As a result, between the continuous drive side one-way clutch 10a and the continuous drive side (drive motor M2 side) and the roller shaft 2b side, when the continuous drive side is the drive side, the continuous drive side is rotated from the continuous drive side. It is transmitted to the roller shaft 2b and the roller shaft 2
When the side b is the drive side, the power is not transmitted from the roller shaft 2b to the continuous drive side. That is, when the drive motor M2 is driven and rotated, the continuous rotation of the drive motor M2 is transmitted to the roller shaft 2b and the seeding conveyor 2 is brought into a continuous transfer state. 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. 4 is not driven and does not transmit. As a result, when the piston C1a of the air cylinder C1 is actuated by a constant stroke at a predetermined timing, the intermittent drive shaft 14 is intermittently rotated by a constant angle, and the roller shaft 2b is intermittently driven and rotated, and the seeding conveyor 2 Becomes an intermittent transfer state. Also, with the intermittent drive side one-way clutch 17 as a boundary, the intermittent drive side (air-cylinder C
(1 side) and the roller shaft 2b side, when the intermittent drive side becomes the drive side, the intermittent drive side transmits to the roller shaft 2b and the intermittent rotation causes the roller shaft 2b to rotate as described above. The air cylinder C1 does not operate, and the continuous drive mechanism
Even if the laser shaft 2b side is continuously driven, the continuous rotation is not transmitted from the intermittent 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.

Since the drive mechanism of the seeding conveyor 2 is constructed as described above, the seedling box 4 placed on the transfer belt 2f is moved by switching the operation of the motor M2 and the air cylinder C1. Direction or continuous transfer.
The speed at which the seedling box 4 placed on the transfer belt 2f is continuously transferred by the motor M2 is the same as the moving speed V1 of the seedling box 4 placed on the first conveyor 1a. And the air-cylinder C1.
Therefore, the speed of intermittent transfer is naturally V3, which is slower than V1.

In the third conveyor 3, like the second conveyor 1b, a conveyor belt 3b is wound around a conveyor roll shaft 3a supported by a frame, and a sprocket 3c provided on the conveyor roll shaft 3a. The chain 3d is wound around and is driven by the transfer motor M3. As a result, the seedling box 4 placed on the conveyor belt 3b between the frames is continuously transferred in the belt moving direction when the transfer motor M3 rotates, and stopped when it stops. The seedling box 4 placed on the third conveyor 3 is
Moving speed V1 of the seedling box 4 placed on the first conveyor 1a
It is configured to be transferred at the same speed V1 as.

The seedling box 4 has a length and width of 3 which is generally used.
The size is 0 cm × 60 cm, and a synthetic resin seedling raising pot P is placed in this box. This seedling pot P
Is a form in which the edges of the small pots p ... are vertically and horizontally connected, and the bottom (one hole is formed) side is independent, and 10 × 20 pots p ... are vertically and horizontally arranged and connected. It was done. This small pot p of this nursery pot P ...
