[0003]

DISCUSSION OF THE INVENTION When flat seeds are sown with a normal seeding device, the direction of the seeds is not constant and the cotyledons are not fixed in the cell. For example, when a machine is used for grafting using a grafting device, grafting cannot be successfully performed unless the orientation of the cotyledons is constant. In addition, the cotyledons may overlap in the cell, resulting in development failure. Therefore, it is an object of the present invention to provide a dedicated seeding device capable of sowing flat seeds in an appropriate posture in a fixed direction.

The present invention provides the following seeding device in order to achieve the above objects. That is, a seed hopper and a seed aligning device that receives seeds from the seed hopper and aligns the seeds in the long axis direction, and the seeds that are aligned by the seed aligning device are adsorbed and transported to the position of the tray for adsorption. Characterized by a seeding machine configured with an adsorption nozzle, in which the seed aligning device is composed of a vibrating body vibrated by a vibrating machine, the vibrating body being a tapered guiding part connected to a seed hopper and the The flat seed sowing machine is composed of a tunnel-shaped aligning part continuous with the guide part, and a suction nozzle insertion port opened at the upper end of the tip of the tunnel-like aligning part.

[0005]

[Operation] The seeds supplied from the hopper to the tapering expansion guiding section are sequentially aligned while being guided by the tapering guiding section by the vibration of the vibrating body by the vibrating machine, and are arranged in a row in the tunnel-shaped aligning section one by one. Then, it is adsorbed by the adsorption nozzle inserted into the adsorption nozzle insertion opening opened at the upper end of the tip, conveyed to the position of the tray, and seeded in the pot.

Since the vibrating body (4) is constructed as described above, the flat seeds fed from the hopper (3) toward the feeding port (7) are sequentially arranged while being guided by the tapered guiding portion, The seeds facing the insertion opening (9) at the tip are adsorbed by the adsorption nozzle (10), transported and seeded in the pot of the transfer device (1) by advancing by aligning one grain at a time in the tunnel-shaped alignment portion. To be done. Since the tunnel holes of the tunnel-shaped aligning section are of a size in which seeds are aligned in a row one by one, seeds are aligned in the holes.

Next, the concrete device of the seeder will be described with reference to FIG. 4. The support plate (12) is laid horizontally and the longitudinal adjustment tool (13) is fixedly installed.
The front-rear direction adjuster (13) allows the fitted rod (15) to move in the front-rear direction by rotating the knob (14), and the rod (15) is provided at the tip of the rod (15). The vertical adjustment tool (17) is externally fitted onto the (16) and the knob (18) is rotated to make the cylinder (19) attached to the vertical adjustment tool (17) adjustable in the vertical direction. ) Piston rod (2
0) A pressure suppressor (21) is arranged at the tip. The pressure suppressor (21) is provided with the same number of protrusions as the number of the seedling raising pots (2) placed on the tray, and the pressure suppressor (21) can be adjusted back and forth and vertically by the knob (14) or the knob (18). By extending the cylinder (19), a hole for inserting the seed into the soil filled in the seedling-growing pot is drilled.

A lateral cylinder (22) which extends and contracts in the front-back direction is arranged on the side of the side plate (11), and the lateral cylinder (22) is fixed to the side plate (11) by its piston rods (23) (23).
