A method of using the described grain seed processing equipment, comprising the following steps:

Step 1: Add the grains to be processed into the feeding port 100, start the blower 103 and the vibration motor at the same time, and preliminarily sort the grains through the wind selection of the blower 103 and the vibration of the first sieve plate, and the first impurities larger than the grains and the shriveled grains are removed. The grain particles are blown to the direction of the first impurity removal port, and the full grain particles and the second impurities smaller than the grain particles fall on the second screen plate;

Step 2: The plump grain particles and the second impurities falling on the second sieve plate are screened by the vibration of the second sieve plate, and the second impurity falls on the bottom surface of the third cavity, and the plump grain particles are collected under the action of gravity At the first discharge port 106; the first impurities collected in the first impurity removal port and the shriveled grain particles are sucked into the trash collection box 104 after being pumped by the negative pressure fan 105 to the trash collection box 104;

Step 3: The plump grain grains are transported to the conveyor belt 107 through the first discharge port 106, and are transported through the conveyor belt 107 through the feeding port 109 and the second rotating shaft 115 in turn. When the baffle is on, the pressure sensor senses and sends a signal to the controller, so that the controller controls the rotation of the second shaft 115 and the high-pressure pump starts to deliver the liquid medicine to the nozzle 113 and spray it out through the nozzle hole, so as to make the full grain particles While being spun out, the surface is sprayed with liquid medicine, and then falls on the bottom surface of the mixing box 108;

At the same time, the controller controls the rotation of the second shaft 115, and at the same time controls the high-pressure pump to start, so that the liquid medicine tank supplies the liquid medicine to the spray pipe 113, so that the full grain particles are rotated and dispersed, and the spray pipe 113 sprays the liquid medicine at the same time. , and the staggered arrangement of the nozzles 113 makes the liquid medicine spray the liquid medicine from different directions, which increases the contact probability and contact area between the liquid medicine and the full grain particles; when the grain particles fall on the ground of the mixing box 108, the weight sensor senses When the weight on the bottom surface exceeds the preset maximum threshold, a controller will control the rotation of the first rotating shaft 112 to drive the stirring plate 114 to stir the grain particles, so that the surface of the grain particles covered by the sprayed liquid medicine is formed. The liquid medicine is more uniform, and at the same time, there will inevitably be liquid medicine on the bottom surface, so that the liquid medicine and grain particles are fully mixed, because the liquid medicine sprayed out by the controller is the grain seeds and liquid medicine liquid that are put into the box. The matching dosage range is sprayed, so the final mixing process can also make full use of the chemical liquid to avoid too much or too little coating of the full grain grains with the chemical liquid, which will affect the overall quality of the seeds.

In a preferred solution, the power switch of the heating wire is turned on after step 2 and before step 3, and the temperature adjustment switch is adjusted to be in a low temperature state.

In the above scheme, after step 2 and before step 3, the power switch of the heating wire is turned on, and the temperature adjustment switch is adjusted to be in a low temperature state, so that the temperature in the mixing box 108 can be slowly changed, and it is avoided to directly adjust the grain seeds to be dried.
