[0002] Seed coating is a high-tech for promoting agricultural production and harvest developed in the mid-1980s. Seed coating is to evenly coat the surface of seeds with a seed coating agent containing various components such as insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents and film-forming agents by mechanical or manual methods in a certain proportion to form a smooth and firm drug film. After the seeds coated with the seed coating agent are sown, they can quickly absorb water and swell.

A sprocket mechanism 237 is provided between the middle part of a rotating shaft 235 and the output shaft of the driving motor 232, and the driving motor 232 is used to drive one of the rotating shafts 235 to rotate through the sprocket mechanism 237. For technicians in the relevant field, the sprocket mechanism 237 is a well-known technology, so it is not described in detail; two shaft seats 234 are respectively passed through the two ends of the rotating shaft 235 and a roller 236 is fixedly provided, and the outer circumference of the mixing drum 21 is rolled on the roller 236; two limit rings 238 are fixedly provided on the outer circumference of the mixing drum 21 with left and right intervals, and the two limit rings 238 are located between the front and rear rollers 236, and the limit rings 238 are used to limit the position of the mixing drum 21 on the roller 236 to prevent the mixing drum 21 from being displaced in the left and right directions when the roller 236 drives the mixing drum 21 to rotate.

Compared with the frequent loading and unloading of seeds, this method only needs to feed materials into the hopper 33 to continuously mix the seeds for a long time. At the same time, in cooperation with the spiral blades 22 inside the mixing cylinder 21, while the mixing cylinder 21 rotates to mix the seed coating agent and seeds, it conveys the seeds to the right, and discharges the seeds with the mixing and coating completed from the discharge port of the mixing cylinder 21, so as to achieve the purpose of automatically coating and discharging the seeds and improve the seed coating efficiency.

[0029] A regulating plate 36 is provided to the right of the discharge hole 35. A regulating mechanism 37 is provided on the storage bin 33.

An internally threaded sleeve 374 is fixedly arranged at the upper right side of the regulating plate 36. The internally threaded sleeve 374 is threadedly sleeved on the screw rod 372.

[0030] By turning the turning handle 373 to drive the screw rod 372 to rotate, under the action of the thread of the screw rod 372, the internally threaded sleeve 374 and the regulating plate 36 are driven to move up and down, opening, closing or adjusting the size of the discharge hole 35. It can not only stop or start feeding the material into the mixing cylinder 21 at any time, but also achieve the purpose of adjusting the feeding speed of the material, so as to adjust the feeding speed according to different types and sizes of seed materials, so that the mixing cylinder 21 can convey the seeds through the spiral blade 22 on the premise of fully mixing the seed coating agent and the seeds.

[0031] Two L-shaped guide plates 375 arranged at intervals before and after are fixedly arranged at the right end of the storage bin 33. A guide chute is jointly formed between the L-shaped guide plate 375 and the right end of the storage bin 33. The front and rear ends of the regulating plate 36 are slidably arranged up and down in the guide chute to guide the regulating plate 36 when it slides up and down.

Specifically, the infusion mechanism includes a medicine box 41 fixedly arranged on the chassis 1. The medicine box 41 contains the seed coating agent. An infusion pump 42 is fixedly arranged on the medicine box 41. The inlet pipe of the infusion pump 42 is fixedly connected and communicated with the medicine box 41. The outlet pipe of the infusion pump 42 is fixedly connected and communicated with a connecting pipe 43. The other end of the connecting pipe 43 extends to the inlet of the mixing cylinder 21 and is fixedly provided with a nozzle. The nozzle is used to evenly spray the seed coating agent onto the seed material located at the inlet of the mixing cylinder 21.

[0033] Working principle: When coating seeds, turning the handle 373 drives the screw 372 to rotate. Under the action of the threads of the screw 372, the internal thread sleeve 374 and the adjusting plate 36 move up and down, opening and adjusting the size of the discharge hole 35 to an appropriate size. At the same time, the vibration motor 38 is started, and the seed material in the bin 33 is evenly and continuously conveyed into the mixing cylinder 21 through the discharger 34. At the same time, the liquid infusion mechanism and the driving device 23 are opened, and the infusion pump 42 sprays the seed coating agent in the medicine box 41 evenly onto the seeds entering the mixing cylinder 21 through the connecting pipe 43 and the nozzle. At the same time, the driving motor 232 drives one of the rotating shafts 235 and the drums 236 located at both ends thereof to rotate through the sprocket mechanism 237, thereby driving the mixing cylinder 21 to rotate along the multiple drums 236, so as to achieve the purpose of mixing the seed coating agent and the seeds inside the mixing cylinder 21. While the mixing cylinder 21 rotates, the spiral blade 22 inside it rotates, so that while the mixing cylinder 21 rotates to mix the seed coating agent and the seeds, it also conveys the seeds to the right, and discharges the seeds with the coating completed from the discharge port of the mixing cylinder 21, realizing the purpose of automatically coating and discharging the seeds.
