[0071] During the work, the pretreated seeds are added through the loading hopper 03, the power is started, the belt conveyor 24 is started, and the seeds are driven to move a certain length of path.

[0072] After the pretreatment is completed, the seeds enter the buffer block 37 in the motor 31 through the feeding tube 38, and then fall into the rotating circle 43 through the opening window 44 to achieve addition. In the process of adding, the rotating circle 43 rotates through the transmission 33 and the power tube 29 to disturb the seeds, so that the opening window 44 intermittently cooperates with the permanent magnet 16 to achieve expansion and continuous intermittent feeding, so that the early seeds can better contact the coating agent, avoiding the accumulation of excessive seeds, and the probability of internal seeds contacting the coating agent is small, and the problem of needing to extend the time occurs, and during the rotation At the same time, the high-pressure pump pumps the coating agent to the dispersion tube 12 and the rigid tube 11, and then enters the installation tube 21 through the hose 02, further enters the pressure head 47 through the extension tube 46, and is finally sprayed by the spray head 48 for coating. The rotation of the rotating circle 43, the continuous spraying of the spray head 48 and the intermittent feeding of the open window 44 ensure that the seeds are quickly and evenly coated. After the second coating, the whole device is stopped, and then the material taking door is opened, the telescopic rod 20 is opened, the power box 17 is tilted, and the rotating circle 43 rotates slowly at the same time to assist in discharging and complete the work.

[0073] During the secondary coating process, the air pump works synchronously as needed to make the gas in the rotating circle 43 flow, thereby making the seeds dry and the coating agent more uniform, and assisting the coating work.
