Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seed stirring and coating machine. Background Art

[0002] Seed coating involves wrapping seeds with non-seed materials such as fungicides, insecticides, micronutrient fertilizers, plant colorants, or fillers using adhesives or film-forming agents. This technique aims to spherically shape the seeds or essentially maintain their original shape, thereby improving stress and disease resistance, accelerating germination, promoting seedling establishment, and increasing yield and quality. Coating agents are typically viscous and often mix unevenly, resulting in uneven seed coating, even clumping and cracking, resulting in inferior seed quality and affecting germination rates after sowing.

[0003] Therefore, seeds generally require seed coating equipment. Seed coating equipment is generally a device that stirs seeds with coatings on the surface until the coating is evenly coated on the seeds. Since the coating has a certain viscosity, the existing seed coating equipment is generally equipped with a variety of stirring devices for stirring to ensure the coating effect of the seeds in the coating equipment. However, the stirring devices of this type of equipment are driven separately by multiple drive motors (such as the patent with application number 202322340009.4), which leads to high production and use costs of the coating equipment, and the equipment is relatively complex and heavy. At present, there is a need to study a device that can stir multiple stirring devices with only one drive motor, and can ensure the stirring effect of seeds and coatings, and ultimately ensure the coating effect.

An annular spray pipe 6 is coaxially fixed to the top of the kettle body 1, and spray holes are evenly provided at the bottom of the annular spray pipe 6. The liquid sprayed downward through the spray holes in the annular spray pipe 6 is sprayed to the area between the spiral blade 8 and the scraper 10.

[0026] The bottom of the stirring shaft 7 is located above the connection between the seed discharge pipe 4 and the spherical surface 2. The bottom of the scraper 10 is fixedly connected to the bottom of the stirring shaft 7 through the arc plate 11. The connection between the arc plate 11 and the scraper 10 is located on the outside of the upper opening of the seed discharge pipe 4. The connection between the arc plate 11 and the stirring shaft 7 is located at the bottom of the side wall of the stirring shaft 7.

[0027] On one side of the bottom of the scraper 10 , an arc-shaped shovel plate 12 is provided below the arc-shaped plate 11 . The shovel plate 12 is tilted upward along the rotation direction of the scraper 10 .

[0028] The shovel plate 12 is inclined outwardly in a direction away from the stirring shaft 7 along the rotation direction of the scraper 10 .

[0029] The bottom end of the spiral blade 8 extends downward to the connection between the arc plate 11 and the stirring shaft 7 .

[0030] The inner edges of the scraper 10 are fixedly connected by a plurality of annular connecting rings 13 , which are coaxially arranged with the kettle body 1 , and are evenly spaced from top to bottom along the inner wall of the scraper 10 .

[0031] There are also multiple arc-shaped stirring blades 14 evenly distributed around the stirring shaft 7. The arc-shaped stirring blades 14 are fixedly connected to the annular connecting rings 13 respectively, and the arc-shaped stirring blades 14 are respectively located between two adjacent scrapers 10. The arc-shaped stirring blades 14 are inclined upward along the rotation direction of the stirring shaft 7.

[0033] The plane where the scraper 10 is located is perpendicular to the portion of the spherical arc surface 2 that it contacts.

[0034] A spray head 15 is fixedly provided on the top of the side wall of the kettle body 1 on one side of the seed feeding hopper 3 , and the liquid medicine sprayed by the spray head 15 is sprayed toward the seeds that fall from the feeding hopper 3 and enter the kettle body 1 .

[0035] The amount of liquid medicine sprayed by the spray head 15 is within a range of 1 / 3 to 2 / 3 of the amount of liquid medicine required for the seeds in the kettle body 1 .

When the amount of seeds in the kettle body 1 reaches the rated stirring amount of the kettle body 1, the valve of the spray head 15 is closed; then the driving motor 9 continues to drive the scraper 10, the curved plate 11 and the curved stirring blade 14 and the shovel plate 12 to stir the seeds in the kettle body 1 for a period of time, and then open the valve connected to the annular spray pipe 6, and the annular The spraying pipe 6 sprays the remaining amount of liquid medicine to the seeds in the area between the spiral blade 8 and the scraper 10, and the driving motor 9 continuously drives the scraper 10, the curved plate 11 and the curved stirring blade 14 as well as the shovel plate 12 to stir the seeds in the tank body 1. When the annular spraying pipe 6 has completely sprayed the corresponding liquid medicine, the driving motor 9 continues to drive the scraper 10, the curved plate 11 and the curved stirring blade 14 as well as the shovel plate 12 to stir the seeds in the tank body 1 for at least 5 to 10 minutes. After the set continuous stirring time is reached, the sampling device can be placed at the bottom of the seed discharge pipe 4, and then the valve plate 5 can be opened for sampling. After the sampling is completed, the valve plate 5 can be closed immediately. If it is found that the sampling is If the coating uniformity and coating effect of the seed sample do not meet the requirements, the seed sample will be put into the feeding hopper 3, so that the seed sample will fall into the kettle body 1 again and continue to be stirred; if it is found that the coating uniformity and coating effect of the seed sample after sampling meet the requirements, the seed sample will be retained; sampling is performed multiple times until the seed samples sampled twice in a row meet the requirements of seed coating uniformity and coating effect. At this time, the driving motor 9 is turned off, and then the seed collecting device is placed at the bottom of the seed discharge pipe 4, and the valve plate 5 is opened to collect the seeds in the kettle body 1. The sampled seeds that met the coating requirements before can also be put into the seed collecting device after retaining evidence.
