As one of the important food crops in the world, wheat seeds are not only the raw material for human staple food (such as flour, bread, etc.), but also an important source of animal feed and industrial processing. Before wheat is planted, it is usually necessary to coat the wheat seeds with coating equipment to achieve the purpose of preventing and controlling diseases and pests in the seedling stage, promoting growth and development, and increasing crop yields.

[0017] 2. Specifically, the first air chamber, the extraction port and the dust extractor in the extraction component generate negative pressure to extract the straw, husk and other debris separated from the wheat seeds, thereby avoiding the waste of the agent and improving the effective utilization rate of the coating agent in the coating process;

[0018] 3. Specifically, the pretreatment component is used to screen out wheat seeds with smaller particles and fine granular debris mixed between wheat seeds through a V-shaped support mounting plate combined with an array of screening holes, so as to improve the quality of wheat seeds;

[0019] The lifting device provided therein can drive the lifting support frame to lift and lower in a vertical direction along the top of the V-shaped support mounting plate, so that the ejecting rod provided on the support mounting rod can enter and exit the screening hole with the cooperation of the ejecting block, which can not only prevent the screening hole from being blocked by wheat seeds or other debris, but also the impact bar provided therein can impact the top of the V-shaped support mounting plate, cooperate with the provided blowing mechanism, accelerate the separation of wheat straw, wheat husk and other debris mixed between the wheat seeds from the wheat seeds, and form upper and lower coordinated cooperation with the extraction component, so as to improve the extraction effect of wheat straw, wheat husk and other debris mixed between the wheat seeds;

The coating agent in the medicine storage box 902 is extracted by the pumping pump 904, and then sprayed to the wheat seeds sliding and rolling on the top of the second guide plate 7 by the atomizing nozzles 903 for medicine spray coating. Subsequently, the wheat seeds after medicine spray coating are guided by the second guide plate 7 to the stirring assembly 8.

[0051] like Figure 10 to Figure 11As shown, the stirring assembly 8 includes a supporting baffle 801 arranged at the bottom of one end of the second guide plate 7, the bottom of the supporting baffle 801 is connected to the inner surface of the bottom of the box body 1, and a stirring chamber is formed between the supporting baffle 801 and the inner surface of the box body 1 on the side away from the second guide plate 7, and the wheat seeds guided down from the second guide plate 7 will enter the stirring chamber; at least two rotating shafts 802 are arranged longitudinally between the inner surface of the box body 1 on the side away from the second guide plate 7 and the supporting baffle 801, and the supporting baffle 801 at one end of the rotating shaft 802 is connected to the inner surface of the box body 1 on the side away from the second guide plate 7. 1 is provided with a driving motor 803 on its outer surface, the output end of the driving motor 803 is connected to one end of the rotating shaft 802, a plurality of stirring plates 804 are equidistantly provided on the circumferential outer surface of the rotating shaft 802, a heating block is provided inside the stirring plates 804, a second rotating sealing door 805 is provided at the bottom ends of both longitudinal sides of the box body 1 corresponding to the position of the rotating shaft 802, a recovery box 806 is provided on the outer surface of the bottom of the box body 1 below the rotating shaft 802, and a plurality of drain grooves 807 are equidistantly provided along the longitudinal direction at the bottom of the box body 1 below the rotating shaft 802, The drain trough 807 is connected to the recovery box 806. A plurality of exhaust vents are arranged on the outer surface of one lateral side of the box body 1 above the rotating shaft 802. An exhaust fan 808 is arranged at the exhaust vent. The rotating shaft 802 is driven to rotate by the driving motor 803, so that the stirring plate 804 stirs the wheat seeds after being sprayed and coated with the agent, so that the coating agent is fully in contact with the outer surface of the wheat seeds and wrapped on its outer surface. At the same time, the excess coating agent will enter the recovery box 806 along the drain trough 807 during the stirring of the wheat seeds, so as to be recycled and reused later. After the coating agent is fully in contact with the wheat seeds and wrapped on its outer surface, the heating block arranged in the stirring plate 804 starts to work, dries the coated wheat seeds and solidifies the coating layer on its surface. The steam generated during the drying and solidification process of the coating layer on the surface of the wheat seeds will be discharged from the box body 1 through the exhaust fan 808. Finally, the wheat seeds with the dried and solidified surface coating layer are discharged from the box body 1 through the second rotating sealing door.

[0052] The longitudinal ends of the V-shaped support mounting plate 501, the first material guide plate 6, the second material guide plate 7 and the support partition 801 are respectively sealed and connected to the inner surfaces of the longitudinal sides of the box body 1 to prevent wheat seeds from leaking from the gaps on the longitudinal sides, maintain the concentration and directionality of the flow, and prevent wheat seeds from accumulating in unnecessary areas; the control regulating valve, the dust collector 203, the lifting device 509, the fan 5022, the heating resistor wire in the heating grid plate 5113, the drive motor 803, the heating block in the stirring plate 804, the exhaust fan 808 and the material pump 904 on the steam transfer tank 3 are all electrically connected to the control device 10 to control the working status of each component, wherein the lifting device 509 is one of a cylinder, a hydraulic cylinder or a servo electric cylinder.

[0053] When in use, after the wheat seeds to be processed enter the box through the feed inlet, they first fall into the top of the V-shaped support mounting plate of the pretreatment component. Under the action of the V-shaped guide channel, the wheat seeds slide down the inclined surface, the sieve holes screen out small-particle inferior seeds and heavy debris, and the screened materials are discharged through the first rotating sealing door. The lifting device drives the lifting support frame to rise and fall periodically, the ejecting rod dynamically clears the sieve holes, and the impact bar vibrates the V-shaped support mounting plate to strengthen the separation of debris. The blowing mechanism blows airflow to the falling seeds through the first blowing port, cooperates with the negative pressure adsorption of the extraction component to remove light debris such as wheat straw and wheat husk, and then the seeds are transferred to the first guide plate through the top of the V-shaped support mounting plate. The second blowing port of the wind heating mechanism releases warm airflow to preheat the seeds, and at the same time, the jet head sprays steam to the wheat seeds sliding on the first guide plate, so as to achieve gradient preheating of the wheat seeds and adjust the surface moisture content of the seeds at the same time;

[0054] Then the wheat seeds are transferred to the second guide plate through the first guide plate. Driven by the pump, the atomizing nozzle of the spray assembly evenly sprays the coating agent on the seeds rolling down the second guide plate to complete the dynamic coating. Then the wheat seeds after coating enter the stirring chamber of the stirring assembly along the second guide plate. The rotating shaft drives the stirring plate with the heating block to stir the seeds in three dimensions, so that the coating agent fully wraps the surface of the seeds. The excess agent flows into the recycling box through the drain trough for recycling. The heating block in the stirring plate is gradually heated to solidify the coating layer and eliminate the internal stress. The exhaust fan synchronously discharges the drying steam. Finally, the seeds that have been coated and solidified are discharged through the second rotary sealing door to complete the whole process of coating treatment. This device achieves efficient utilization of coating agents and comprehensive improvement of the quality of wheat seed coating through the process chain coupling and coordination of screening-airflow impurity removal-gradient preheating-water content adjustment-atomization spraying-stirring solidification-residual liquid recovery.
