Its function is to effectively prevent pests and diseases during seed germination and seedling growth, provide essential nutrients, promote seed germination and seedling growth, enhance the corn's resistance to adverse conditions, and thus improve the emergence rate, seedling survival rate, yield, and quality of the corn.

[0003] However, some existing corn seed coating machines are unable to agitate and coat the corn seeds inside and in various locations, which not only reduces the coating efficiency but may also affect the coating effect.

[0004] Therefore, those skilled in the art have provided a corn seed coating machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a corn seed coating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A corn seed coating machine includes a first motor mounting frame; a first motor is fixedly connected to the upper middle side of the first motor mounting frame, a main rotating shaft is fixedly connected to the output end of the first motor, a main gear is fixedly connected to the outer side of the main rotating shaft, driven gears mesh on the left and right sides of the main gear, a driven rotating shaft is fixedly connected to the inside of the driven gear, a stirring shaft is fixedly connected to the lower side of the driven rotating shaft, several side stirring rods are fixedly connected to the left and right ends of the outer side of the stirring shaft, a lower mounting frame is fixedly connected to the lower side of the stirring shaft, and several bottom stirring rods are fixedly connected to the lower side of the lower mounting frame.

[0007] As a further embodiment of this utility model, the upper four ends of the first motor fixing frame are fixedly connected to connecting blocks, and the upper side of the connecting blocks is fixedly connected to a movable slide plate. The left and right sides of the movable slide plate have slots for several slide plate grooves.

[0008] As a further embodiment of this utility model, the movable slide plate has a threaded rod connected to its internal center thread, a second motor is fixedly connected to the upper side of the threaded rod, and an upper fixed frame is fixedly connected to the upper side of the second motor.

[0009] As a further embodiment of this utility model, a mixing tank is fixedly connected to the lower side of the upper fixed frame, and a feed inlet is fixedly connected to the upper ends of the left and right sides of the mixing tank. A control valve is rotatably connected to one side of the feed inlet.

[0010] As a further embodiment of this utility model, a mixing tank cover plate is hinged to the middle of the front side of the mixing tank, and a movable handle is fixedly connected to the right end of the front side of the mixing tank cover plate.

[0011] As a further embodiment of this utility model, a seed coating agent storage box is fixedly connected to the lower side of the mixing box, a quantitative scale is fixedly connected to the middle of the front side of the seed coating agent storage box, and side inlet pipes are fixedly connected to the upper ends of the left and right sides of the seed coating agent storage box.

[0012] As a further embodiment of this utility model, a liquid guide pipe is fixedly connected to the middle of the left and right sides of the seed coating agent storage box, and a pump is fixedly connected to the outside of the liquid guide pipe.

[0013] As a further embodiment of this utility model, a rear fixing frame is fixedly connected to the middle of the rear side of the seed coating agent storage box, a hot air blower is fixedly connected to the upper side of the rear fixing frame, a first air guide pipe is fixedly connected to the upper side of the hot air blower, a plurality of second air guide pipes are fixedly connected to the front side of the first air guide pipe, and a filter screen is fixedly connected to the front side of the interior of the second air guide pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By starting the first motor, the corn seeds in the mixing tank are stirred and coated. This not only continuously agitates the corn seeds, ensuring that each seed has ample contact with the seed coating agent, but also guarantees that the agent evenly coats the surface of the seeds, preventing some seeds from being over-coated while others are barely coated. Furthermore, seed coating agents often contain multiple functional ingredients, such as fungicides, insecticides, and nutrients. Stirring ensures that these different components are evenly distributed on the surface of the corn seeds, guaranteeing that each seed receives balanced protection and nutrient supply. Stirring also allows the corn seeds to complete the coating process in a short time, significantly increasing the number of seeds coated per unit time, thereby improving... To improve the efficiency of the device, the continuous stirring action of the bottom stirring rod breaks up the corn seeds that are gathered at the bottom of the mixing tank, constantly turning them over and dispersing them. This ensures that every corn seed can participate in the entire mixing and coating process, avoiding a situation where a large number of seeds at the bottom of the mixing tank are not fully mixed and coated. Furthermore, some seed coating agents contain certain sticky components. If the corn seeds remain stagnant at the bottom for a long time after contact with them, they are prone to sticking together and forming clumps. The bottom stirring rod, by constantly stirring the corn seeds at the bottom, can effectively prevent this sticking, ensuring that the corn seeds are relatively independent and evenly dispersed. This is conducive to the seed coating agent evenly coating each corn seed, which can further improve the coating quality.

[0015] 2. The coated corn seeds can be dried by turning on the hot air blower. This not only removes moisture from the seed coating agent, but also allows the film-forming substances in the agent to dry and solidify quickly, forming a uniform, firm, and continuous protective film on the surface of the corn seeds. This reduces the risk of mold and rot during subsequent storage, ensuring the germination rate and vigor of the corn seeds. Furthermore, appropriate drying temperature and time can promote better penetration of the active ingredients in the coating agent into the corn seeds, enhancing the protective and promoting effects of the coating agent. Additionally, the lower moisture content of the dried coated corn seeds reduces problems such as clumping and overheating caused by moisture during storage and transportation, helping to maintain the fluidity and looseness of the corn seeds, facilitating handling and long-term storage.

[0016] 3. The filter screen not only intercepts dust, impurities, and other particles in the hot air, preventing them from adhering to the surface of the corn seeds and causing contamination, thus avoiding subsequent mold growth and ensuring a clean appearance for the corn seeds, which is beneficial for storage and post-sowing growth, but also allows the hot air to be more evenly distributed as it passes through. This uniform hot air can act more comprehensively and evenly on the corn seeds, helping to evaporate moisture evenly from the surface of the seeds during the drying process, making the seed coating agent dry and solidify more consistently, improving the uniformity and firmness of the coating, and ensuring that each corn seed receives good coating and drying results.

Detailed Implementation

[0024] Please see Figures 1-4In this embodiment of the invention, a corn seed coating machine includes a first motor mounting bracket 1; a first motor 2 is fixedly connected to the upper middle side of the first motor mounting bracket 1; a main rotating shaft 3 is fixedly connected to the output end of the first motor 2; a main gear 4 is fixedly connected to the outer side of the main rotating shaft 3; driven gears 5 mesh on the left and right sides of the main gear 4; a driven rotating shaft 6 is fixedly connected inside the driven gear 5; a stirring shaft 7 is fixedly connected to the lower side of the driven rotating shaft 6; and several side stirring rods 8 are fixedly connected to the left and right ends of the outer side of the stirring shaft 7. A lower fixing frame 9 is fixedly connected to the lower side of the stirring shaft 7, and several bottom stirring rods 10 are fixedly connected to the lower side of the lower fixing frame 9; a connecting block 11 is fixedly connected to the four ends of the upper side of the first motor fixing frame 1, and a movable slide plate 12 is fixedly connected to the upper side of the connecting block 11. Several slide plate grooves 13 are cut on the left and right sides of the movable slide plate 12; a threaded rod 14 is threadedly connected to the middle of the interior of the movable slide plate 12, a second motor 15 is fixedly connected to the upper side of the threaded rod 14, and an upper fixing frame 1 is fixedly connected to the upper side of the second motor 15. 6; A mixing tank 17 is fixedly connected to the lower side of the upper fixed frame 16. Feed inlets 18 are fixedly connected to the upper ends of the left and right sides of the mixing tank 17. A control valve 19 is rotatably connected to one side of each feed inlet 18. A mixing tank cover plate 20 is hinged to the middle of the front side of the mixing tank 17. A movable handle 21 is fixedly connected to the right end of the front side of the mixing tank cover plate 20. A seed coating agent storage tank 22 is fixedly connected to the lower side of the mixing tank 17. A quantitative scale 23 is fixedly connected to the middle of the front side of the seed coating agent storage tank 22. A control valve 19 is rotatably connected to one side of each side of the seed coating agent storage tank 22. A side inlet pipe 24 is fixedly connected to the upper end; a liquid guide pipe 25 is fixedly connected to the middle of the left and right sides of the seed coating agent storage box 22, and a pump 26 is fixedly connected to the outside of the liquid guide pipe 25; a rear fixing frame 27 is fixedly connected to the middle of the rear side of the seed coating agent storage box 22, a hot air blower 28 is fixedly connected to the upper side of the rear fixing frame 27, a first air guide pipe 29 is fixedly connected to the upper side of the hot air blower 28, a plurality of second air guide pipes 30 are fixedly connected to the front side of the first air guide pipe 29, and a filter screen 31 is fixedly connected to the front side of the inside of the second air guide pipe 30.

[0025] The working principle of this utility model is as follows: When it is necessary to coat corn seeds, the corn seeds can be put into the mixing tank 17 through the feed inlet 18. During the process of putting the corn seeds into the mixing tank 17, the speed at which they fall into the mixing tank 17 can be controlled by the control valve 19, thereby avoiding the situation where too many corn seeds fall into the mixing tank 17 at one time, which would prevent the corn seeds from being completely coated. Then, the first motor 2 is started, which drives the main rotating shaft 3 to rotate. The main rotating shaft 3 drives the main gear 4 to rotate. The main gear 4 drives the driven gears 5, driven rotating shafts 6 and mixing shafts 7 on its left and right sides to rotate. Then, the side mixing rods 8, the lower fixed frame 9 and the bottom mixing rod 10 are rotated. At the same time, the pumps on the left and right sides of the mixing tank 17 are started. 26. Then, pump 26 extracts the seed coating agent from the seed coating agent storage tank 22 and delivers it to the surface of the corn seeds in the mixing tank 17 through the liquid guide pipe 25. The seed coating process can then begin. Starting the first motor 2 stirs and coats the corn seeds in the mixing tank 17, continuously agitating the seeds and ensuring each seed has ample contact with the seed coating agent. This guarantees even coating of the seeds, preventing some seeds from being over-coated while others are barely coated. Furthermore, the seed coating agent often contains various functional ingredients such as fungicides, insecticides, and nutrients; stirring ensures these different ingredients are evenly distributed on the surface of the corn seeds. This ensures that each corn seed receives relatively balanced protection and nutrient supply. Furthermore, the stirring action allows the corn seeds to complete the coating process quickly, significantly increasing the number of seeds coated per unit time and thus improving the device's efficiency. The continuous stirring action of the bottom stirring rod 10 breaks up the corn seeds that are clustered at the bottom of the mixing tank 17, constantly turning and dispersing them to ensure that each corn seed participates in the entire mixing and coating process. This avoids a situation where a large number of seeds at the bottom of the mixing tank 17 are not fully mixed and coated. Additionally, some seed coating agents contain certain sticky components; if the corn seeds remain stationary at the bottom for a long time after contact with the agent, they can easily stick together. The seeds initially clump together, but the bottom stirring rod 10 continuously agitates the corn seeds at the bottom, effectively preventing this clumping and ensuring that the seeds are relatively independent and evenly dispersed. This facilitates the even coating of each seed with the seed coating agent, further improving the coating quality. After coating is complete, the pump 26 is turned off, and the hot air blower 28 is started to blow hot air at a suitable temperature. The hot air generated by the hot air blower 28 is then blown through the first air guide duct 29 and the second air guide duct 30 onto the surface of the coated corn seeds in the mixing box 17. The coated corn seeds can then be dried by starting the hot air blower 28, thus removing moisture from the seed coating agent.The rapid drying and solidification of the film-forming substance in the seed coating agent forms a uniform, firm, and continuous protective film on the surface of the corn seeds. This reduces the risk of mold and rot during subsequent storage, ensuring the germination rate and vigor of the corn seeds. Furthermore, appropriate drying temperature and time promote better penetration of the active ingredients in the coating agent into the corn seeds, enhancing its protective and promoting effects. The dried, coated corn seeds, due to their lower moisture content, are less prone to clumping and overheating during storage and transportation, maintaining their fluidity and looseness for easy handling and long-term storage. After drying, the first motor 2 and hot air blower 28 can be turned off, and the second motor 15 can be started. The second motor 15 drives the threaded rod 14 to rotate, which in turn moves the movable slide plate 12 upwards along the slide plate groove 13. The movable slide plate 12 then drives the connecting block 11 and the first motor... The fixed frame 1 moves upward, which in turn moves the stirring shaft 7, side stirring rod 8, lower fixed frame 9, and bottom stirring rod 10 upward. Once in the desired position, the movement stops. Then, the mixing chamber cover 20 is opened using the moving handle 21, allowing the corn seeds inside the mixing chamber 17 to be collected. The filter 31 not only intercepts dust, impurities, and other particles in the hot air, preventing them from adhering to the surface of the corn seeds and causing contamination, thus avoiding subsequent mold growth and ensuring a clean appearance for the corn seeds, which is beneficial for storage and post-sowing growth, but also allows the hot air to be more evenly dispersed. This even distribution of hot air helps to more comprehensively and evenly affect the corn seeds, promoting uniform evaporation of moisture during the drying process. This results in more consistent drying and curing of the seed coating agent, improving the uniformity and firmness of the coating, and ensuring that each corn seed achieves good coating and drying results.
