Description

Technical Field

[0001] This utility model relates to the field of peanut planting technology, specifically to a high-oleic acid peanut seed coating device. Background Technology

[0002] High-oleic peanuts contain over 75% oleic acid, while ordinary peanuts contain approximately 54%. High-oleic peanuts not only boast high nutritional value and excellent storage properties, but their oleic acid content is comparable to that of olive oil, earning them the nickname "peanut-olive fruit." They represent the future direction of peanut production and consumption. With continuous economic development and accelerated urbanization, market demand for high-oleic peanuts is constantly increasing, leading to the widespread cultivation of high-oleic peanut varieties. To ensure seed survival rates, peanut seeds need to be coated before planting to improve insect and disease resistance. Current peanut seed coating devices generally include feeding and discharging mechanisms, mixing mechanisms, or rotary mixing mechanisms. Coating devices using rotary mixing mechanisms, in particular, are widely used due to their high coating efficiency and ability to uniformly coat high-oleic peanut seeds.

[0003] However, existing high-oleic peanut seed coating devices have been found to have a large amount of coating agent residue adhering to their rotating mixing drum after the peanut seed coating process is completed. This residue is difficult to clean and can easily harden and clump together, affecting the subsequent peanut seed coating effect. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a high-oleic acid peanut seed coating device, which facilitates the effective scraping of peanut seed coating agent adhering to the inner wall of the rotating mixing drum, makes cleaning of the rotating mixing drum easier, effectively avoids the problem of residual coating agent clumping and hardening inside the rotating mixing drum, ensures the effect of subsequent peanut seed coating, and solves the problems mentioned in the background art.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-6As shown, a high-oleic peanut seed coating device includes a rotating cylinder 1 with one end open. A first circular cover 2 and a second circular cover 3 are respectively rotatably fitted onto both ends of the rotating cylinder 1. The bottom of the first circular cover 2 and the second circular cover 3 are fixedly mounted on the same bracket 4. One end of the rotating cylinder 1 is fixedly connected to a guide pipe 5, which rotatably passes through the first circular cover 2. A feed hopper 6 is fixedly installed on one side of the first circular cover 2, and the bottom end of the feed hopper 6 extends into the guide pipe 5. The bottom of the second circular cover 3 is fixedly connected to a discharge hopper 7. A ring gear 8 is fixedly fitted onto the guide pipe 5. A motor 9 is located on one side of the first circular cover 2, and a gear 10 is mounted on the output shaft of the motor 9. 10 meshes with the ring gear 8. An annular scraper 11 is slidably installed inside the rotating cylinder 1. An annular plate 12 is rotatably installed on one side of the annular scraper 11. Four pull rods 13 arranged in a ring array are fixedly installed on one side of the annular plate 12. The pull rods 13 slide through the second circular cover 3. The same pull plate 14 is fixedly installed on the side of the four pull rods 13 away from the annular plate 12. Through the simple scraping structure, it is easy to effectively scrape off the peanut seed coating agent adhering to the inner wall of the rotating mixing cylinder, thereby facilitating the cleaning of the rotating mixing cylinder. It can effectively avoid the problem of residual coating agent caking and hardening in the rotating mixing cylinder, and can ensure the effect of subsequent peanut seed coating. The pull plate 14 also includes a first circular hole 15. A circular hole 15 passes through the two sides of the pull plate 14. A locking block 16 slides through the first circular hole 15. The locking block 16 is fixed to one side of the second circular cover 3. A cavity 21 is formed on the locking block 16. A second circular hole 17 passes through the top and bottom inner walls of the cavity 21. A slot 18 is formed on the top and bottom inner walls of the first circular hole 15. An internally threaded cylinder 19 is slidably installed in the second circular hole 17. One end of the internally threaded cylinder 19 is slidably installed in the corresponding slot 18. The two internally threaded cylinders 19 are internally threaded with the same bidirectional lead screw 20. The bidirectional lead screw 20 rotates through the cavity 21 and is fixedly sleeved with a first bevel gear 22. A rotating rod 23 is provided at one end of the locking block 16. One end of 23 extends into the chamber 21 and is equipped with a second bevel gear 24, which meshes with the first bevel gear 22. This arrangement facilitates the quick locking and releasing of the pull plate 14, and allows for the easy pulling of the annular scraper 11 to clean the inner wall of the rotating cylinder 1. This effectively prevents the annular scraper 11 from moving during peanut seed coating operations. A third circular hole is penetrating the first circular cover 2, through which the guide pipe 5 rotates and passes. The third circular hole facilitates the guide pipe 5 extending out of the first circular cover 2 and connecting to the feed hopper 6. An L-shaped bracket is fixedly installed on one side of the first circular cover 2, and the motor 9 is fixedly installed on the L-shaped bracket. The L-shaped bracket facilitates the installation of the motor 9.The rotating cylinder 1 has multiple ribs arranged in a circular array fixedly installed inside. The rotating cylinder 1 is inclined. The outer wall of the annular scraper 11 has multiple through slots arranged in a circular array. The ribs slide through the corresponding through slots. By setting the ribs, it is easy to spread peanut seeds evenly. The pull plate 14 has two handles. One side of the annular scraper 11 has an annular groove. An annular locking block is rotatably installed in the annular groove. The annular locking block is fixed to the annular plate 12. By setting the annular groove and the annular locking block, it is easy for the annular plate 12 to move. The bidirectional screw 20 is rotatably connected to the annular scraper 11. A retaining plate is fixedly installed inside the second circular hole 17. The bidirectional screw 20 rotatably passes through both retaining plates. A limiting groove is formed on one side of the inner wall of the second circular hole 17, and a limiting block is slidably installed in the limiting groove. The limiting block is fixed to the corresponding internal threaded cylinder 19. By setting the retaining plate, the bidirectional screw 20 is easily supported and limited. A fourth circular hole is formed on one side of the inner wall of the chamber 21, and the rotating rod 23 rotatably passes through the fourth circular hole. By setting the fourth circular hole, the rotating rod 23 is easily supported and limited.

[0037] The working principle of this utility model is as follows: In use, motor 9 is first turned on, which drives gear 10 to rotate. Gear 10 drives ring gear 8 to rotate, which in turn drives guide pipe 5 to rotate. Guide pipe 5 drives rotating cylinder 1 to rotate within the first circular cover 2 and the second circular cover 3. Simultaneously, rotating cylinder 1 drives annular scraper 11 to rotate. Then, high-oleic peanut seeds and coating agent are fed into rotating cylinder 1 through feed hopper 6 and guide pipe 5, allowing the peanut seeds to mix evenly with the coating agent during rotation, forming a coating on the surface of the peanut seeds. The coated peanut seeds continuously roll into the second circular cover 3 and are discharged through discharge hopper 7. After the peanut seeds are coated, motor 9 is turned off. Then, rotating rod 23 is turned, which drives second bevel gear 24 to rotate. Second bevel gear 24 drives first bevel gear 22 to rotate, which in turn drives bidirectional lead screw 20 to rotate, causing the two internal threaded cylinders 19 to slide out of their corresponding slots 18, thus fixing the pull plate 14. This design facilitates the quick locking and releasing of the pull plate 14, allowing for easy removal of the annular scraper 11 to clean the inner wall of the rotating cylinder 1. This effectively prevents the annular scraper 11 from moving during peanut seed coating. After pulling the pull plate 14, the locking block 16 slides out of the first circular hole 15. The pull plate 14 then drives multiple pull rods 13 to extend from the rotating cylinder 1 and the second circular cover 3. Simultaneously, the multiple pull rods 13 move the annular plate 12, which in turn moves the annular scraper 11 to scrape away coating agent residue from the inner wall of the rotating cylinder 1. This continues until the annular scraper 11 moves into the second circular cover 3, where the coating agent falls into the discharge hopper 7 and is discharged. This design effectively removes the peanut seed coating agent adhering to the inner wall of the rotating mixing cylinder, facilitating cleaning and preventing the coating agent from hardening and caking within the cylinder, thus ensuring the effectiveness of subsequent peanut seed coating.
