A method of using the grain seed processing apparatus, comprising the steps of:

step 1: adding grains to be processed into the feeding hole 100, starting the air blower 103 and the vibrating motor at the same time, performing air separation on the grains through the air blower 103 and performing vibration on the first sieve plate to perform primary separation on the grains, blowing first impurities larger than the grains and shriveled grains to the direction of the first impurity removing hole, and sieving the plump grains and second impurities smaller than the grains onto the second sieve plate;

step 2: the plump grain particles and second impurities falling onto the second sieve plate are screened by the second sieve plate in a vibration mode, the second impurities fall onto the bottom face of the third cavity, and the plump grain particles are collected at the first discharge hole 106 under the action of gravity; the first impurities and the shriveled grain particles collected at the first impurity removing port are sucked into the impurity collecting box 104 after the air of the impurity collecting box 104 is exhausted by the negative pressure fan 105;

and step 3: the full grain particles are conveyed to the conveying belt 107 through the first discharging hole 106, the full grain particles sequentially pass through the feeding hole 109 and the second rotating shaft 115 through the conveying belt 107, when falling onto a baffle plate in the second rotating shaft 115, the full grain particles are sensed by the pressure sensor and send signals to the controller, so that the controller controls the second rotating shaft 115 to rotate and the high-pressure pump to start to convey liquid medicine to the spraying pipe 113 and spray the liquid medicine through the spraying holes, the full grain particles are sprayed with the liquid medicine on the surfaces of the full grain particles while being rotated out, and then the full grain particles fall onto the bottom surface of the stirring box 108;

and 4, step 4: after the full grain particles fall on the bottom surface of the stirring box 108, the full grain particles are sensed by the weight sensor and send signals to the controller, and the controller controls the motor to start so as to drive the first rotating shaft 112 to rotate, so that the stirring plate 114 turns and mixes the full grain particles falling on the bottom surface of the stirring box 108.

In the above scheme, the grain to be processed is added into the feeding hole 100 of the box body, and the blower 103 and the vibrating motor are simultaneously started to blow the impurities such as straw, miscellaneous leaves or shriveled grain, mildewed grain and other light grain particles to one side by blowing wind of the blower 103 so as to be separated from the high-quality full grain particles, and the full grain particles fall on the second sieve plate through the vibration of the first sieve 101, in the process, after the air is extracted from the impurity collecting box 104 by the negative pressure fan 105, the internal pressure of the impurity collecting box 104 is reduced, so that a large amount of dust existing in the grain particles is sucked into the impurity collecting box 104 together with other impurities and light grain particles after being blown by the wind; the plump grain particles falling onto the second sieve plate are vibrated, impurities, such as fine sand, which are doped in the second sieve plate and smaller than the grain particles, are filtered to a second impurity removing opening on the bottom surface of the box body, and the second impurity removing opening is collected by a visitor, the plump grain particles remained on the second sieve plate are collected by the second sieve plate, because the second sieve plate is obliquely arranged, the plump grain particles can be collected to the first discharging opening 106 under the action of gravity, the plump grain particles are transmitted to the conveyor belt 107 through the first discharging opening 106, the conveyor belt 107 is further transmitted to the stirring box 108, the specific plump grain particles enter the second rotating shaft 115 through the feeding opening 109, when the plump grain particles pass through the baffle of the second rotating shaft 115, on one hand, the baffle slows down the descending speed of the plump grain particles, on the other hand, the pressure sensor on the baffle senses that the grain passes through, and when the pressure on, the controller controls the second rotating shaft 115 to rotate, and controls the high-pressure pump to start at the same time, so that the liquid medicine is supplied to the spray pipe 113 by the liquid medicine tank, the spray pipe 113 sprays the liquid medicine while the full grain particles are rotationally dispersed, and the spray pipes 113 are arranged in a staggered manner, so that the liquid medicine is sprayed from different directions, and the contact probability and the contact area between the liquid medicine and the full grain particles are increased; when the cereal grain falls to the subaerial time of agitator tank 108, when weight sensor senses that the weight on the bottom surface exceeds the maximum threshold value of predetermineeing, will have the rotation of the first pivot 112 of controller control, turn over and mix to cereal grain with drive stirring board 114, make the liquid medicine that is wrapped up in on the cereal grain surface that is sprayed the liquid medicine more even, can not avoid having the existence of liquid medicine on the bottom surface simultaneously, make liquid medicine and cereal grain intensive mixing, because of controller control spun liquid medicine, it sprays with liquid medicine assorted dose scope to be through the cereal seed of throwing into the box, consequently last turn over and mix the process and can also make full use of liquid medicine, avoid too much or too little wrapping up in the liquid medicine of plump cereal grain, in order to influence the whole quality of seed.

In a preferable scheme, after the step 2 and before the step 3, a power switch of the heating wire is opened, and the temperature adjusting switch is adjusted to be in a low-temperature state.

In the above scheme, the power switch of the heating wire is turned on after step 2 and before step 3, and the temperature adjusting switch is adjusted to be in a low-temperature state, so that the temperature in the stirring box 108 can be slowly changed, and the phenomenon that the activity of seeds is damaged by directly adjusting the temperature at which the cereal seeds can be dried to influence the seed quality is avoided.
