Description

Technical Field

[0001] This utility model relates to the technical field of seed coating machines, specifically a dustproof coating machine for corn seed processing. Background Technology

[0002] Seed coating for corn is a key technology in modern agricultural seed processing. Its core principle is to uniformly coat the surface of corn seeds with a coating solution composed of pesticides (such as insecticides and fungicides), fertilizers, growth regulators, film-forming agents, and trace elements using mechanical or chemical methods, forming a protective film with a certain strength and functionality. This technology not only provides physical protection for the seeds but also achieves multiple objectives through the slow-release effect of the coating components. For example, the pesticide components in the coating solution can effectively kill pathogens and insect eggs carried on the seeds, or form a protective layer during seed germination to resist soil-borne pests and diseases, reducing the incidence of seedling diseases. Furthermore, fertilizers and growth regulators can provide nutrients in the early stages of seed germination, promoting root development, robust seedling growth, and improving seed germination rate and stress resistance (such as drought and cold resistance).

[0003] However, in existing corn seed coating processing, traditional equipment is insufficient to meet the demands of refined production. Specific pain points are as follows:

[0004] Severe dust pollution: Corn seeds contain dust and impurities, which are easily stirred up during processing. This not only pollutes the workshop environment and threatens the health of workers, but also adheres to the coating liquid pipelines and nozzles, affecting the coating quality. Traditional equipment lacks efficient dust prevention and removal structures, making it difficult to solve the dust problem.

[0005] Poor coating uniformity: When seeds are coated with coating liquid while static or simply turned over, uneven coating is likely to occur in some areas, resulting in weak protection and growth promotion effects on some seeds, affecting the germination rate and disease and pest resistance of subsequent planting, and failing to meet the needs of precision planting.

[0006] Therefore, those skilled in the art have provided a dustproof coating machine for corn seed processing to solve the problems mentioned in the background art. Utility Model Content

A fixed frame 15 is fixedly connected to the right side of the machine body 1. A servo motor 16 is fixedly installed on the fixed frame 15. A rotating shaft 17 is fixedly connected to the power output end of the servo motor 16. One end of the rotating shaft 17 is fixedly connected to the roller 14. A discharge port 12 is opened at the lower end of the machine body 1. An electric control valve 13 is fixedly installed on the discharge port 12. The electric control valve 13 can control whether the discharge port 12 discharges material. A support base 25 is fixedly connected to the lower end of the machine body 1. A base 26 is fixedly connected to the lower end of the support base 25. A conveying assembly 27 is fixedly installed on the upper end of the base 26. A receiving bucket 28 is set above the conveying assembly 27. The receiving bucket 28 has two sides. A limit rod 29 is provided, which can limit the receiving bucket 28 to prevent it from deviating from the direction during transmission. A threaded column 30 is rotatably connected to one side of the limit rod 29. The threaded column 30 is threaded to the side wall of the support base 25. A rotating disk 31 is fixedly connected to one end of the threaded column 30. A sliding rod 32 is provided in front of and behind the threaded column 30. The sliding rod 32 is slidably connected to the side wall of the support base 25, and one end of the sliding rod 32 is fixedly connected to the limit rod 29.

A sealing cap 7 is threadedly connected to the upper end of the medicine inlet 6. The sealing cap 7 can prevent dust from entering the medicine tank 5.

[0027] The working principle of this utility model is as follows: In use, corn seeds are first poured into the drum 14 through the inlet / outlet 19, and the inlet / outlet baffle 21 is inserted into the inlet / outlet 19 to seal it. During installation, the slider 24 is first slid towards the center, causing the spring rod 23 to move towards the center. Then, the slider 24 is released, allowing the spring rod 23 to spring back and insert into the slot 20. The sealing door 2 is then closed, creating a relatively enclosed working space for the machine body 1, reducing dust leakage. Next, the servo motor 16 is started, driving the rotating shaft 17 to rotate. The rotating shaft 17 then drives the drum 14 to rotate. The filter screen 1 on the drum 14... 8. The dust and impurities in the corn seeds are sieved out. At the same time, the dust collection device 11 is activated. The suction generated by the dust collection port 10 is used to suck up and collect the fine dust and impurities floating in the drum 14 and at the bottom of the machine body 1. Larger impurities settle to the bottom of the machine body 1 due to gravity. This completes the seed pretreatment and cleaning. Then, the receiving bucket 28 is placed on the conveying assembly 27 and conveyed to the area below the discharge port 12. Next, the electric control valve 13 is opened to allow the impurities at the bottom of the machine body 1 to fall into the receiving bucket 28. Then, the dust collection device 11 and the electric control valve 13 are closed, and the coating liquid is injected into the medicine tank 5 through the medicine inlet 6. The coating liquid flows along the connecting pipe 8 to the nozzle 9. The seeds continue to tumble as the drum 14 rotates. In this state, nozzle 9 will evenly spray the coating liquid onto the seed surface, achieving all-round coating through seed rolling, forming a protective film, thereby achieving the functions of preventing pests and diseases and promoting germination and growth. After coating is completed, open the sealing door 2 and manually pull the slider 24 to move it to the center. The slider 24 drives the spring rod 23 to move to the center, and the spring rod 23 will disengage from the slot 20. Then, the inlet and outlet baffle 21 can be removed from the inlet and outlet 19. Then, control the servo motor 16 to adjust the angle of the drum 14 so that the inlet and outlet 19 face downwards. The corn seeds in the drum 14 will flow out from the inlet and outlet 19 due to gravity and fall to the bottom of the machine body 1. Then, place the new receiving bucket 28. The corn seeds are placed on the conveying assembly 27 and conveyed to the area below the discharge port 12. Then, the electric control valve 13 is opened, allowing the corn seeds to fall into the receiving bucket 28. At the same time, multiple receiving buckets 28 can be placed on the conveying assembly 27 and moved one after another to the area below the discharge port 12 to receive the corn seeds. In addition, the rotating disk 31 can be manually rotated, which can drive the threaded column 30 to rotate. The threaded column 30 drives the limiting rod 29 to move towards the center. The two limiting rods 29 on the left and right can limit the receiving buckets 28 on the conveying assembly 27 to prevent them from deviating during conveying. The left and right positions of the limiting rods 29 can be adjusted to accommodate receiving buckets 28 of different widths.
