DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seed rice dewatering machine.

[0002]

2. Description of the Related Art In a conventional seed dewatering machine, seeds after dehydration are artificially removed from the dewatering machine.

[0003]

Conventionally, sowing pretreatment for germinating seeds, dewatering and supplying the seeds to a seeding plant is troublesome, and the efficiency of sowing is poor in terms of pretreatment. Had become. An object of the present invention is to provide a seed rice dewatering machine that can perform pretreatment for sowing efficiently, can be easily automated, and has a simple structure.

[0004]

In order to achieve the object, the seed rice dewatering machine according to the present invention is provided with a centrifugal dewatering tank for seed rice rotatably rotatable, and the seed rice in the centrifugal dewatering tank is centrifuged. The vertical peripheral wall inner surface is formed on a conical surface that expands upwardly from the centrifugal dehydration tank by ascending the vertical peripheral wall inner surface of the centrifugal dehydration tank for power, receiving and collecting seeds from the centrifugal dehydration tank. And a paddy discharger that sends out the paddy from the paddy outlet to the outside of the dehydrator. The operation and effect are as follows. Any kind of paddy receiving portion for receiving the seed paddy from the centrifugal dewatering tank of the paddy discharger may be adopted, but the use of the driving rotary type is advantageous as follows.

[0005]

When the seeds are artificially or automatically supplied to the centrifugal dewatering tank, the centrifugal dewatering tank applies a centrifugal force for dehydration to the seeds and performs dehydration by centrifugal dewatering. When the seed rice is subjected to the centrifugal force, the centrifugal force and the inner surface shape of the vertical peripheral wall portion of the dewatering tub raise the vertical peripheral wall portion and jump out of the dewatering tub. The paddy discharged from the dehydration tub is received and collected by the paddy discharger, and sent out of the paddle through the paddy outlet. If the paddy receiving part of the paddy ejector is made to be a rotary drive type, when the seed paddy coming out of the dewatering tank collides with the paddy receiving part and is collected, it will collide due to the rotation of the paddy receiving part in the same direction as the dewatering tank. Collision occurs in a state where the stop impact due to is reduced.

[0006]

According to the present invention, the action of the vertical peripheral wall of the dewatering tank and the paddy discharger allows the paddy to automatically come out of the dehydrator, and the dewatered paddy can be obtained only by receiving it from the paddy outlet. Seeding can be easily and efficiently supplied to the seeding hopper compared to the conventional method that was artificially removed, or the seeding hopper can be relatively easily structured simply by adding a conveyor from the dehydrator to the seeding hopper. Can now be automated to be supplied automatically. In addition, since the centrifugal force for dewatering the seed rice is used for automatic removal, a relatively simple structure requiring only a discharger is sufficient, which is economically advantageous. When the paddy receiving portion of the paddy discharger is of a rotary drive type, the paddy is discharged while being hardly damaged, and it is easy to avoid poor germination or germination failure due to damage to the seed paddy.

The seedling box conveyor transports the seedling boxes so as to pass under each of them, and sows rice seeds by a well-known seeding plant B that can automatically supply floor soil, seeds, and cover soil to the nursery boxes. In order to perform the treatment, the seed rice is disinfected, immersed, germinated, dehydrated, and supplied to the seeding plant B. The details are configured as follows.

That is, the seed rice germination tank 1 is configured to disinfect, immerse, and germinate the seed rice G by throwing the seed rice G out of the bag in a loose state and immersing it in the treatment liquid W inside the tank. It is. The first paddy carrier unit 2 includes a pump 2a, a take-out hose 2b extending from a suction part of the pump 2a, and a supply hose 2c extending from a discharge part of the pump 2a. The sprouting seed paddle that has been processed in the seed paddy germination tank 1 is installed by setting the outlet end side inside the seed paddy germination tank 1 and installing the extending end side of the supply hose 2 at the padding inlet 6 of the seed paddy dewatering machine 3. G is taken out of the seed germination tank 1 together with the internal treatment liquid W of the seed germination tank 1 by the suction action of the pump 2a, and is conveyed and supplied to the seed germ dewatering machine 3 by the feed action of the pump 2a. The seed paddy dewatering machine 3 receives the seed paddy G from the paddy inlet 6 by a centrifugal dewatering tank 8 attached to the body 7 so as to rotate around the vertical axis X, and rotates the centrifugal dewatering tank 8 by a motor 9. By being configured to apply a centrifugal force for dewatering to the seed paddy G, the sprout seed paddy G from the first paddy conveying device unit 2 is subjected to dehydration treatment by forced dehydration by centrifugal dehydration. By forming the centrifugal dewatering tank 8 by a tapered drum as shown in FIG. 2, the inner peripheral surface 8a of the vertical peripheral wall of the centrifugal dewatering tank 8 becomes upwardly conical and the seed rice G inside the centrifugal dewatering tank 8 is used for dewatering. Due to the centrifugal force applied to the paddle, the vertical peripheral wall inner surface 8a is lifted up and pops out of the centrifugal dewatering tank 8, and the paddy discharger 10 provided at the upper part of the body 7 as shown in FIG.
