Description

Technical Field

[0001] This utility model relates to the field of seed processing technology, and more specifically, to a seed coating film drying machine. Background Technology

[0002] Seed coating film drying machine is a key piece of equipment in seed processing. It is mainly used to evenly coat the seed surface with coating agents (such as pesticides, fertilizers, biostimulants, etc.) and quickly dry them into a film to improve the seed's disease resistance, germination rate and agronomic performance.

[0003] Existing seed coating machines lack the function of seed dispersion coating during the coating process, which makes it difficult to uniformly coat clumps of seeds, resulting in uneven seed coating.

[0004] A search revealed a seed coating machine disclosed in Chinese Patent No. CN220087898U. This utility model features a circular guide hole on the bottom side of the inner side of the guide cylinder, with several ball bearings rolling along the inner wall of the guide hole. This allows the seeds to pass through the guide hole when they are introduced into the coating machine through the guide cylinder. The rotating stirring shaft and spiral sleeve push and disperse the clumps of seeds. The rubber spiral sleeve and the rolling ball bearings prevent damage to the seeds during the dispersion process.

[0005] In practical use, the seed coating agent needs to be poured into the seeds separately and stirred by the staff during the addition process, and the staff needs to add it repeatedly, which affects the efficiency of seed coating. Utility Model Content

[0025] Reference Figure 4 and Figure 7As shown, the drying mechanism includes three heaters 25. The outer side of the heaters 25 is fixedly connected to the inner side of the outer casing 1. Multiple fans 26 are fixedly connected to the bottom of the outer casing 1. Multiple positioning tubes 27 are fixedly connected to the inner side of the outer casing 1. A connecting rod 28 is slidably connected to the inner side of the positioning tube 27. A spring 29 is sleeved on the outer side of the connecting rod 28. A vibration frame 30 is fixedly connected to the top of the spring 29. The bottom of the vibration frame 30 is fixedly connected to the top of the connecting rod 28. A vibration motor 31 is fixedly connected to the bottom of the vibration frame 30. Multiple air guide frames 32 are provided at the bottom of the vibration frame 30. The air guide frames 32 have a trapezoidal cross section. Multiple screens 33 are fixedly connected to the outer side of the vibration frame 30.

The three heaters 25 heat the vibration frame 30, and the multiple fans 26 blow air onto the bottom of the vibration frame 30 to fully dry the seeds so that they can be coated into a film.

[0026] The working principle of this invention is as follows: When coating seeds, the seeds are first poured into the feed pipe 2, and then enter the drum 12 through the feed pipe 2. A servo motor 10 drives two gears 11 to mesh with the toothed grooves 14 on the outer side of the transmission ring 13, allowing the drum 12 to rotate. Simultaneously, multiple support wheels 7 and 24 provide auxiliary support for the transmission ring 13 and positioning wheel 17 on the outer side of the drum 12. Then, the drum 12 drives multiple stirring rods 15 on its inner side to agitate the seeds. Next, the water inlet pipe 23 is opened, and the coating agent is injected into the concentrator 18. Then, the pressure pump 19 and air pipe 20 are activated to pressurize the inside of the concentrator 18. The coating agent inside the concentrator 18 is then fed into the water pipe 21. The coating agent is then sprayed into the drum 12 through multiple nozzles 22 on one side of the water pipe 21, and the seeds are thoroughly coated by the multiple stirring rods 15 on the inner side of the drum 12. Stirring ensures the coating agent fully coats the seeds. After full coating, the servo motor 10 drives the gear 11 to reverse, causing the drum 12 to reverse as well. Multiple inclined baffles 16 on the inner side of the drum 12 output the seeds. The output seeds fall inside the outer shell 1 onto the vibrating frame 30. Three heaters 25 heat the inside of the vibrating frame 30, and multiple fans 26 blow air onto the bottom of the vibrating frame 30. Multiple air guides 32 at the bottom of the vibrating frame 30 concentrate and guide the air through the screen 33 to the seeds at the top of the vibrating frame 30. The vibrating motor 31 vibrates the vibrating frame 30, which is then cushioned by multiple positioning tubes 27, connecting rods 28, and springs 29. Finally, after the coating agent on the seed surface dries, the seeds move from one side of the collection box 4 and are collected inside the collection box 4.
