Seed coating can not only improve the germination rate and emergence rate of seeds, but also effectively prevent and control diseases and pests at the seedling stage and promote the healthy growth of crops.

[0003] Traditional seed coating methods often rely on manual operations, resulting in uneven seed coating and complicated operations. Existing seed coating devices are prone to seed agglomeration or adhesion during the stirring process, resulting in uneven coating. Therefore, we propose a seed coating device. Utility Model Content

The output shaft of the motor passes through a through hole provided at the bottom of the connecting box and is fixedly connected to the connecting shaft. A conical rotating table is welded to the bottom of the connecting shaft. The outer sides of the conical rotating table are in active contact with the inner bottom sides of the mixing barrel. Mixing units are respectively provided at the front and rear ends of the bottom of the support frame.

[0005] As a preferred technical solution of the utility model, ventilation holes are arranged at equal distances on the top of four sides of the connection box.

[0006] As an optimal technical solution of the utility model, the mixing unit consists of a pressure plate, a push plate, a compression spring, a fixed frame, a sliding rod, a material dividing block and a shoveling block. There are two fixed frames, which are symmetrically arranged front and back at the inner middle part of the mixing barrel, and sliding rods are slidably installed in the sliding holes arranged at the ends of the fixed frames, and a material dividing block and a shoveling block are fixedly installed at the bottom of the sliding rod, a push plate is fixedly installed on the top of the sliding rod, and a compression spring is arranged at the bottom of the push plate, and the compression springs are respectively sleeved on the outside of the sliding rod, and the upper and lower ends of the compression spring are fixedly connected to the bottom of the push plate and the top of the fixed frame, respectively, and a pressure plate is arranged directly above the push plate, and the pressure plate is a Z-shaped structure, and the opposite ends of the pressure plate are fixedly connected to the outer top of the connecting box.

The material dividing block and the shovel block at the bottom of the slide rod respectively divide and stir the seed materials on the conical rotating table, so that the seeds can be more fully contacted with the coating liquid.

[0010] When the seed material is coated, the electric telescopic rod brings the rotating unit upward, so that the edges of the conical rotating table are offset from the inner wall of the mixing barrel to form a "discharging" gap. Under the action of the compression spring, the push plate drives the sliding rod, the dividing block and the shoveling block to move upward, and the motor drives the conical rotating table to rotate through the connecting shaft.
