[0017] 1. In combination with the drying air cylinder, filter cartridge, fixed sleeve and stirring roller, the seeds can be coated effectively and dried quickly to prevent the medicaments attached to the surface of the seeds from falling off and affecting the subsequent protection of the seeds. The internal structure of the drying air cylinder generates wind force when working, and the wind force is used to quickly dry the coated seeds.

[0018] 2. Combined with the screen box, diverter slots, screen holes and other structures, the seeds after coating and drying can be screened, so that impurities mixed in the seeds can be effectively removed to prevent the impurities from being stored with the seeds, thereby affecting the subsequent use of the seeds. When the treated seeds fall onto the upper surface of the screen box under the action of the guide plate, they will flow along a plurality of diverter slots equidistantly opened on the surface of the screen box, and then the seeds can be effectively screened using the screen holes opened at the bottom of the diverter slots. The size of the screen holes will be smaller than the size of the seeds, and the screened impurities will fall into the inner side of the screen box for centralized storage, which is convenient for subsequent manual cleaning, and is convenient and quick, with higher overall practicality.

[0019] 3. Combined with the second motor, eccentric wheel, guide rod and reset spring and other structures, the subsequent longitudinal reciprocating motion of the Xi'an screen box can be convenient, and the screen box can be used to better filter and remove impurities for the processed seeds. The operation of the second motor will cause the eccentric wheel connected to its output end to rotate accordingly, and then when the eccentric wheel rotates, it will push the screen box, and then the screen box will move longitudinally along the guide rod through the sliding sleeve, and when the sliding sleeve moves longitudinally, it will squeeze the reset spring and cause it to deform accordingly, so that the longitudinal reciprocating motion of the screen box can be realized by utilizing the reverse force generated by the deformation of the reset spring and the rotation of the eccentric wheel, which is convenient for the subsequent better filtering and impurity removal of the seeds.

[0033] The first motor 23 and the second motor 34 are both electrically connected to an external power source through a wire, and the first motor 23 and the second motor 34 are both controlled by a controller, and the two can work independently;

[0034] When the seeds to be processed are input into the inner side of the processing chamber 3, the first motor 23 is powered on to rotate the linkage shaft 24 connected to its output end. Since the linkage shaft 24 is fixedly connected to the drying air cylinder 6, the rotation of the linkage shaft 24 can realize the rotation of the drying air cylinder 6, thereby utilizing the rotation of the drying air cylinder 6 to drive the shaft 7 to rotate accordingly. When the shaft 7 rotates, it drives the fixed sleeve 9 to move, so that it drives the stirring roller 11 to rotate inside the processing chamber 3 through the connecting rod 10, and then utilizes multiple The movement of the stirring roller 11 can fully mix the seeds and the coating material so that the material can be evenly covered on the surface of the seeds. When the seed coating is completed, the drying fan 14 arranged in the inner cavity of the drying air duct 6 starts working. Since the linkage shaft 24 is a hollow structure and the linkage shaft 24 is connected to the drying air duct 6, the holes on the surface of the linkage shaft 24 can be used to draw air into the inner side of the drying air duct 6, and the honeycomb filter plate 12 is used to perform preliminary filtration and impurity removal on the air, and then the adsorption carbon plate 13 can be used to fill the air. The dust impurities mixed in the air are removed, and the post-processed air is discharged through a plurality of air outlets 15, so that the processed air is used to dry the coated seeds, thereby improving the drying efficiency of the seeds and making the overall practicality higher. During the drying process, the air inside the original processing chamber 3 is input to the inner side of the shaft rod 7 through the through hole 16, and because the shaft rod 7 is connected to the filter cartridge 8, the air is input to the inner side of the filter cartridge 8 and passes through the filter element 17. The filter element 17 can be used to dry the coated seeds. The original air inside the processing chamber 3 is filtered, and the activated carbon adsorption plate 18 is set to remove impurities with odor in the air, and the treated air will be discharged through the exhaust hole 19 to achieve the purpose of ventilation. At the same time, it can prevent the air from being mixed with impurities such as odor to pollute the surrounding environment. Subsequently, the extraction pump 22 works to draw the processed seeds inside the processing chamber 3 into the inner side of the extraction pipe 20, and then discharge them through the feeding nozzle 21, so that the processed seeds are input into the inner side of the filter chamber 4.

[0035] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, a first guide plate 25 is distributed below the feed nozzle 21, and a second guide plate 26 is distributed below the first guide plate 25. The first guide plate 25 and the machine body 1 are distributed in an inclined shape, and the first guide plate 25 is symmetrically distributed on the inner side of the machine body 1. A guide frame 27 is installed on the inner side of the bottom of the machine body 1, and a guide rod 28 penetrates the inner side of the guide frame 27. A return spring 29 is sleeved on the outer surface of the guide rod 28, and a sliding sleeve 30 is connected to one end of the return spring 29. A screen box 31 is installed at one end of the sliding sleeve 30, and a diverter groove 32 is opened on one side of the top of the screen box 31. The bottom of the diverter groove 32 is connected to a screen hole 33. A second motor 34 is installed at one end of the bottom of the machine body 1, and an eccentric wheel 35 is connected to the output end of the second motor 34.

[0036] When the processed seeds are input into the inner side of the filter chamber 4, they will move along the first guide plates 25 symmetrically distributed on both sides, and then the processed seeds will fall into the upper surface of the screen box 31 under the action of the first guide plates 25. At this time, the second motor 34 works to rotate the eccentric wheel 35 connected to its output end, and then the rotation of the eccentric wheel 35 will push the screen box 31 longitudinally. Since the screen box 31 is slidably connected to the guide rod 28 through the sliding sleeve 30, when the eccentric wheel 35 rotates, the screen box 31 will move longitudinally, driving the sliding sleeve 30 to slide along the guide rod 28. When the sliding sleeve 30 moves longitudinally, it will also drive the reset spring 29 to deform accordingly. The reverse force generated by the deformation of the return spring 29 and the rotation of the eccentric wheel 35 can realize the longitudinal reciprocating motion of the screen box 31. At this time, the seeds falling into the upper surface of the screen box 31 will be input into the inner side of the diverter groove 32 and flow along the diverter groove 32. The impurity particles mixed in the seeds can be removed by cooperating with the multiple fine sieve holes 33 opened at the bottom of the diverter groove 32. The seeds after screening will fall into one side of the second guide plate 26, which is convenient for subsequent output through the discharge trough 5. Occasionally, the screen box 31 is a hollow structure, so the impurities filtered out will fall into the inner side of the screen box 31, which is convenient for subsequent centralized treatment.

[0037] Specific working principle: when the seeds to be processed are input into the inner side of the processing chamber 3, the first motor 23 is powered on to rotate the linkage shaft 24 connected to its output end, and since the linkage shaft 24 is fixedly connected to the drying air duct 6, the rotation of the linkage shaft 24 can be used to realize the rotation of the drying air duct 6, so as to utilize the rotation of the drying air duct 6 to drive the shaft rod 7 to rotate accordingly, and then when the shaft rod 7 rotates, it will drive the fixed sleeve 9 to move, so that it drives the stirring roller 11 to rotate inside the processing chamber 3 through the connecting rod 10, and then utilize the movement of multiple stirring rollers 11 to fully mix the seeds and the coating material, so that the material can be evenly covered on the surface of the seeds, and when the seed coating is completed, the drying air duct 6 is rotated. The drying fan 14 arranged in the inner cavity of the cylinder 6 works. Since the linkage shaft 24 is a hollow structure and the linkage shaft 24 is connected to the drying air cylinder 6, the holes opened on the surface of the linkage shaft 24 can be used to draw air into the inner side of the drying air cylinder 6, and the honeycomb filter plate 12 is used to perform preliminary filtering and impurity removal on the air, and then the adsorption carbon plate 13 is used to fully remove the dust impurities mixed in the air, and the treated air is discharged through a plurality of air outlets 15, so as to use the treated air to dry the coated seeds, thereby improving the drying efficiency of the seeds and making the overall practicality higher. During the drying process, the air inside the original processing chamber 3 is input into the shaft 7 through the through hole 16. The inner side, and because the shaft 7 is connected with the filter cartridge 8, the air will be input into the inner side of the filter cartridge 8, and pass through the filter element 17. The filter element 17 can be used to filter the original air inside the processing chamber 3, and the activated carbon adsorption plate 18 can be used to remove the impurities emitting odor in the air, and the treated air will be discharged through the exhaust hole 19, so as to achieve the purpose of ventilation. At the same time, it can prevent the air from being mixed with impurities such as odor to pollute the surrounding environment. Subsequently, the extraction pump 22 works to draw the processed seeds inside the processing chamber 3 into the inner side of the extraction pipe 20, and then discharge them through the feeding nozzle 21, so that the processed seeds are input into the inner side of the filter chamber 4. At this time, they are input into the filter chamber 4. The seeds on the two sides will move along the first guide plates 25 symmetrically distributed on both sides, and then the processed seeds will fall into the upper surface of the screen box 31 under the action of the first guide plates 25. At this time, the second motor 34 works to rotate the eccentric wheel 35 connected to its output end, and then the rotation of the eccentric wheel 35 will push the screen box 31 longitudinally. Since the screen box 31 is slidably connected to the guide rod 28 through the sliding sleeve 30, when the eccentric wheel 35 rotates, the screen box 31 will move longitudinally and drive the sliding sleeve 30 to slide along the guide rod 28. When the sliding sleeve 30 moves longitudinally, it will also drive the reset spring 29 to deform accordingly. Combined with the reverse force generated by the deformation of the reset spring 29 and the rotation of the eccentric wheel 35, the longitudinal reciprocating motion of the screen box 31 can be realized.At this time, the seeds falling on the upper surface of the screen box 31 will be input into the inner side of the diverter slot 32 and flow along the diverter slot 32. The impurities and particles mixed in the seeds can be removed by cooperating with the multiple fine screen holes 33 opened at the bottom of the diverter slot 32. The seeds after screening will fall to one side of the second guide plate 26, which is convenient for subsequent output through the discharge slot 5. Since the screen box 31 is a hollow structure, the impurities filtered out will fall into the inner side of the screen box 31, which is convenient for subsequent centralized processing.
