The water pump 4 can draw the coating agent in the coating agent tank 3 out through the liquid inlet pipe 5 by starting the water pump 4. Then, the coating agent can enter the spraying tank 1 through the liquid outlet pipe 6 and be sprayed out through the spray head 15. The upper spraying box 14 on the right side can preliminarily coat the rice seeds. Then, the rice seeds can fall onto the upper second conveying belt 21. The rice seeds can move to the left side. The spraying box 14 on the left side can coat the rice seeds again. Then, the rice seeds can fall onto the lower first conveying belt 18. The rice seeds can move to the right side. The lower spraying box 14 on the right side can further coat the rice seeds. Then, the rice seeds can fall onto the lower second conveying belt 21. The rice seeds can move to the left side. Finally, the rice seeds can be discharged out of the spraying tank 1 through the discharge plate 10. The rice seeds can be blocked by the blocking skirt 22 and the baffle 11 to avoid falling from the side. In this process, the rice seeds can be conveyed multiple times by the two first conveying belts 18 and the two second conveying belts 21. The coating effect on the rice seeds can be improved by the plurality of spraying boxes 14. Since the rice seeds can continuously fall, the rice seeds can be more uniform during coating, and the practicability of the whole device is improved.
