Abstract

PURPOSE:To provide a seeding device, freely advancing or retreating a nozzle from each nozzle guide, having a tacky sealing member applied to the tip of the nozzle and capable of sowing even deformed seed grains from a chute to a tray one by one. CONSTITUTION:This seeding device is obtained by decreasing the diameter of a hole 63 in each nozzle guide 61 from the size of seeds, freely advancing and retreating the nozzle 64 from a nozzle guide thereof and applying a tacky sealing member 65 for bonding each seed to the tip of the nozzle. Thereby, even the only one deformed seed grain can be bonded by the size of the tacky sealing member.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the 408 publication, a communication port is provided in the lower part of the partition plate so that the large hopper and the lower part of the small hopper are communicated, and the seeds in the large hopper move from the communication port to the small hopper along the inclined surface of the bottom of the large hopper. , The seeds are adsorbed by the small hopper, but in this case, when the seeds are oriented vertically and there are flat seeds, several grains may be adsorbed, such as eggplant and tomato. Flat seed sowing accuracy is poor. SUMMARY OF THE INVENTION It is therefore an object of the present invention to eliminate this drawback and obtain a nozzle of a seeding device that can adsorb one by one with a nozzle.

[0004]

The present invention provides the following seeding device in order to achieve the above objects. That is, a sowing that is configured such that the nozzle can be moved forward and backward with respect to the nozzle guide, the tip of the nozzle guide has a diameter smaller than the size of the seed, and an adhesive seal member for adhering the seed is detachably attached to the tip of the nozzle. It is a device.

[0005]

[Operation] The seed in the seed hopper is adhered by the nozzle having the adhesive seal member at the tip. When the seed passes through the nozzle guide having a diameter smaller than the size of the seed, the seed comes into contact with the nozzle guide and is released from the adhesion. Seeded.

The present invention relates to the improvement of the seeding device in the seeding plant as described above. The seeding device shown in Japanese Utility Model Laid-Open No. 2-31408 as an example of the seeding device divides the hopper (39) into a large hopper (39b) and a small hopper (39c) by a partition plate (39a) as shown in FIG. , A funnel (41) having a saucer (40c) formed at the upper end thereof is inserted into the small hopper (39c) side so that the small hopper (39c) can be moved up and down, and a funnel (on the side of the saucer (40c) and on the side of the small hopper (39c) ( 42) the suction nozzle (43) swings, and a communication port (39d) is provided in the lower part of the partition plate (39a) to communicate the lower part of the large hopper (39b) and the small hopper (39c). are doing.

According to the above, the large hopper (39b)
The seeds inside move from the communication port (39d) to the small hopper (39c) along the inclined surface of the bottom of the large hopper (39b),
Since the small hopper (39c) is designed to adsorb seeds, the seeds are oriented vertically, and in the case of flat seeds, multiple seeds may be adsorbed instead of one seed, and sowing of flat seeds such as eggplant and tomato is possible. The accuracy is poor. The present invention improves the above points and is a vacuum adsorption type seeding device capable of adsorbing one by one.

The present invention improves the above points and provides a seeding device capable of adhering one by one. That is, the nozzle is configured to be movable back and forth with respect to the nozzle guide,
Further, in the seeding device, the tip of the nozzle guide has a diameter smaller than the size of the seed, and an adhesive seal member for adhering the seed is detachably attached to the tip of the nozzle. In FIG. 1, reference numeral (61) is a nozzle guide, and a nozzle (64) is configured to be movable back and forth by a cylinder (68) in the hole (63). The tip (62) of the nozzle guide forming the hole (63) has a diameter smaller than the size of the seed. An adhesive tape (65), which is a reusable seal member, is detachably attached to the tip of the nozzle (64) so that seeds can be adhered. The cylinder (68) that drives the nozzle (64) to move back and forth is the cylinder (6
6) A piston rod (67) is pivotally attached (67)
a) and the nozzle (6) towards the seed hopper (60)
4) can be swung while being swung toward the shooter (69), and seeds are put into the tray (70) from the shooter (69). Since the cylinder (68) is pivotally supported (71c) by the arm (71) of the frame, the swinging mechanism of the cylinder (68) causes the piston rod (67).
The cylinder (68) moves to the hopper (60) side around the fulcrum (71c) when the piston moves backward, and the cylinder (68) moves to the shooter (69) side around the fulcrum (71c) when the piston rod (67) projects. It is designed to rock.

The cylinder rod (67) of the cylinder (66) is replaced by the seed hopper (6) of the cylinder (68).
While swinging toward the 0) side, the nozzle (64) is made to project from the hole (63) of the nozzle guide (61) and the seed is adhered to the tip end by the adhesive tape (65). Next, the cylinder (68) is swung to the shooter (69) side by the cylinder (66) and the nozzle (64) is pulled up. Then, since the hole (63) of the tip (62) of the nozzle guide (61) is smaller than the diameter of the seed, the seed comes into contact with the tip (62) to be released from adhesion and falls toward the shooter (69). Then, again in the cylinder (68), the nozzle (64) protrudes from the tip (62) of the nozzle guide (61) and swings in the cylinder (66) to move from the shooter (69) side to the seed hopper (60) side. , Its adhesive tape (71)
The seeds in the seed hopper (60) are adhered again with. still,
Shown is the piston rod (6) of the cylinder (68).
8b) is connected to a bar (68a) with a plurality of nozzles (6
4) is connected. According to the above, even if the seed is irregularly shaped, it adheres to the adhesive seal member,
Only one grain can be adhered in the size of the seal, and since the adhesive seal member is a reusable seal material, it can be used again after washing and can be continuously used. However, if the modified seeds are round seeds, the adsorption type is better. Especially for pumpkin and cucumber, adsorption type is better.

[0013]

According to the present invention, seeds can be surely adhered to each other by the adhesive seal member at the tip of the nozzle, and the seeds are released from the adhesive seal member when they touch the nozzle guide. You can sow grain by grain. Moreover, since the adhesive seal member can be reused again after washing, it can be continuously used, and even irregularly shaped seeds can be adhered by only one grain in the size of the seal, and one grain can be surely sown.
