The storage box 2 contains seeds to be coated, and the storage box 2 is driven by a longitudinal movement driving mechanism and undergoes longitudinal displacement back and forth. The discharge port at the bottom of the storage box 2 is equipped with an electronic control valve and is located inside the box body 1, facilitating the discharge of the seeds in the storage box 2 into the box body 1. Inside the box body 1, a vibrating screen 3 is fixedly installed in a left-high and right-low inclined manner. A vibrating motor 4 is fixed to the bottom of the vibrating screen 3 through bolts. The vibrating screen 3 is driven to vibrate by the vibrating motor 4. A coating agent storage box 5 for storing seed coating agent is fixed to the top of the box body 1 through a support rod. An inlet is fixed to the top of the coating agent storage box 5, facilitating the injection of the coating agent into the coating agent storage box 5. A first water pump 6 is fixed to the bottom of the coating agent storage box 5 through bolts. The output end of the first water pump 6 penetrates the inside of the coating agent storage box 5, and the output end of the first water pump 6 penetrates into the box body 1 and is fixed with a spraying mechanism for spraying the coating agent on the seeds. The seeds to be coated are scattered onto the vibrating screen 3 through the storage box 2, and the longitudinal movement driving mechanism is used to drive the storage box 2 to move longitudinally back and forth, so that the seeds can be evenly scattered. At the same time, the vibrating motor 4 drives the vibrating screen 3 to vibrate, so that the evenly dispersed seeds can be sprayed with the coating agent by the spraying mechanism during the vibration process, so that the coating agent can be evenly attached to the surface of the seeds. A recovery box 7 for recovering the coating agent dripping from the vibrating screen 3 is fixed to the bottom inside the box body 1 through bolts. Box doors are symmetrically hinged to the front of the box body 1 near the recovery box 7 through hinges. A circulation and reflux mechanism is connected between the recovery box 7 and the coating agent storage box 5, facilitating the re-injection of the recovered coating agent into the coating agent storage box 5. An outlet 8 for discharging the coated seeds is provided on the right side wall of the box body 1. The outlet 8 corresponds to the position of the vibrating screen 3. By arranging the recovery box 7 below the vibrating screen 3 to recover the dripping coating agent and using the circulation and reflux mechanism to transport the coating agent collected in the recovery box 7 to the coating agent storage box 5, the excess coating agent can be recycled.

[0022] A through groove is provided on the left side of the top end of the box body 1, and the through groove is adapted to the storage box 2 for the front and back sliding of the storage box 2.

The bottom end of the wind collecting box 25 is provided with ventilation holes arranged at equal intervals. A hot air blower 26 is fixed to the far right side of the top end of the box body 1 by bolts. The air outlet of the hot air blower 26 penetrates through the top end of the box body 1 and extends into the wind collecting box 25. The hot air blower 26 blows air into the wind collecting box 25, and the hot air is then blown out through the ventilation holes at the bottom end of the wind collecting box 25 to dry the seed coating on the seed surface.

[0028] When the seeds need to be coated, first put the seeds to be coated into the storage tank 2, and then open the control valve at the discharge port at the bottom end of the storage tank 2 to make the seeds fall onto the vibrating screen 3. At the same time, use the longitudinal movement driving mechanism to drive the storage tank 2 to longitudinally displace back and forth, so that the seeds therein can be evenly scattered onto the vibrating screen 3. When the seeds fall onto the vibrating screen 3, start the vibrating motor 4 to drive the vibrating screen 3 to vibrate, so that the seeds slide on the vibrating screen 3 in the direction of the discharge port 8. When the seeds slide below the spraying mechanism, start the first water pump 6 to pump out the seed coating agent in the seed coating agent storage tank 5 and inject it into the spraying mechanism, and then the spraying mechanism sprays the seed coating agent on the seed surface, so that the seed coating agent adheres to the seed surface to achieve seed coating. The excess seed coating agent passes through the vibrating screen 3 and falls into the recovery tank 7, and then the circulating reflux mechanism is used to transport the seed coating agent collected in the recovery tank 7 to the seed coating agent storage tank 5 to achieve the recycling of the seed coating agent. When the seeds slide below the wind collecting box 25, start the hot air blower 26 to blow air into the wind collecting box 25, and the hot air is then blown out through the ventilation holes at the bottom end of the wind collecting box 25 to dry the seed coating on the seed surface. Finally, the coated seeds are discharged from the discharge port 8 and can be collected.
