[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The seed disinfection device for crop seed production drives the spiral blade to rotate through motor 2, and transports the seeds from the receiving box through the feed pipe, port 1 and port 2 to the receiving assembly inside the rotating drum. At the same time, the rotation of the rotating drum aligns port 2 with port 1 in sequence, so that the seeds are evenly distributed into the four disinfection chambers, improving the consistency of the disinfection effect. The feeding assembly realizes automatic loading of seeds, reduces manual operation, and reduces labor intensity. The spiral conveying channel formed by the spiral blades can stably and efficiently transport the seeds to the designated position, ensuring the continuity and stability of the loading process.

[0019] 2. During the seed loading process of the seed disinfection device for crop seed production, the rotation of the eccentric wheel causes the connecting plate and the second baffle to vibrate, which works in synergy with the inclined design on the upper surface of the connecting plate to effectively break the seed accumulation state, so that the seeds are quickly and evenly distributed in the disinfection chamber, which helps the seeds to more fully contact the disinfectant, improve the uniformity and effect of disinfection, and the rotation of the drum causes the seeds to continuously roll in the disinfection chamber and be fully mixed with the agent. After the agent spraying is completed, the motor 2 is started again to reverse and drive the eccentric wheel to reverse, so that the connecting plate and the second baffle vibrate again, further promoting the mixing of the seeds and the agent, ensuring that the surface of the seeds can be evenly contacted with the disinfectant, comprehensively improving the disinfection effect, and ensuring the quality of seed disinfection.

[0020] 3. The sealing plate at the opening cooperates with the infusion tube and other components to effectively seal the disinfection chamber, prevent the volatilization of the medicine and the entry of external impurities, maintain the stability of the disinfection environment, ensure that the disinfection process is not disturbed by external factors, and ensure the reliability of the disinfection effect. The support rings at both ends of the drum are embedded in the annular grooves on the inner walls of both sides of the circular shell to provide stable support and limit for the drum, ensuring the stability of the drum during rotation.

[0021] 4. The seed disinfection device for crop seed production drives the drum to rotate through motor 1, which can make the discharge port 2 accurately align with the discharge port 1. The electric telescopic rod controls the lifting and lowering of the baffle plate, controls the discharge timing, and realizes orderly discharge, ensuring that the seeds can be discharged from the disinfection device in sequence and stably, which is convenient for subsequent collection and processing. The vibration generated by the reversal of the eccentric wheel and the design of the upper surface of the connecting plate inclined toward the discharge port, under the dual effects of gravity and vibration, accelerate the discharge of seeds from the disinfection chamber, improve the discharge efficiency, reduce the residual seeds in the device, and ensure the efficient completion of the disinfection process.

[0022] 5. The two baffles are located between the two vertical plates, and the through-rods movably penetrate the through-holes on the vertical plates, which not only prevents seeds from entering the non-working area, but also limits the movement of the connecting plates, ensuring the stable operation of the accommodating components and improving the reliability and stability of the device.

[0051] Gear 18 is mounted on mounting seat 2 13 , a connecting ring 81 is fixedly mounted on gear 18 , a limiting ring 82 is fixedly sleeved on the connecting ring 81 , a connecting shaft 31 rotatably connected to mounting seat 2 13 movably passes through gear 18 and connecting ring 81 , a mounting groove 14 is formed on the surface of mounting seat 2 13 , an annular groove 15 is formed on the inner wall of mounting groove 14 , and the limiting ring 82 is located in annular groove 15 , and is used to support and limit gear 18 to ensure stable rotation of gear 18 ;

[0052] A drive shaft 83 is rotatably mounted on the upper end of the mounting seat 2 13 , and a gear 2 84 and a synchronous wheel 2 85 are fixedly mounted on both ends of the drive shaft 83 , respectively. The gear 2 84 meshes with the gear 1 8 , and a synchronous belt 78 is sleeved on the synchronous wheel 2 85 and the synchronous wheel 1 75 . A gear 3 92 is fixedly mounted on each rotating shaft 9 , and each gear 3 92 meshes with the gear 1 8 , for transmission between the rotating shaft 72 , the drive shaft 83 and the rotating shaft 9 ;

[0053] A motor 1 for driving the rotating drum 3 to rotate is fixedly installed in the mounting seat 11, and an encoder is installed on the output shaft of the motor 1 to accurately control the degree of rotation of the rotating drum 3, so as to facilitate accurate loading and unloading. The connecting shaft 31 rotatably connected to the mounting seat 11 is fixedly connected to the output shaft of the motor 1. The top surface of the mounting seat 11 is designed as an inclined surface. Baffles 12 are fixedly installed on both sides of the upper end of the mounting seat 11, and a support seat 6 is fixedly installed on the upper end of the sealing plate 22. An electric telescopic rod 61 is fixedly installed on the support seat 6, and the telescopic rod of the electric telescopic rod 61 is fixedly connected to a baffle plate 62, which is movably inserted into the discharge port 24. The electric telescopic rod 61 controls the movement of the baffle plate 62 in the vertical direction to realize the opening and closing of the discharging stage.

[0054] The working principle of this embodiment is as follows:

[0055] Step 1: When in use, the operator first adds the crop seeds to be sterilized into the storage box 71, and then starts the motor 2 74. Its output shaft drives the rotating shaft 72 to rotate, and the spiral blade 73 fixed on the rotating shaft 72 rotates accordingly. The spiral blade 73 forms a spiral conveying channel in the storage box 71 and the extension tube 76, pushing the seeds out from the feed pipe 77, and conveying them to the storage component 4 in the storage chamber 36 through the through port 1 21 and the through port 2 35. At the same time, start the motor 1, and the output shaft of the motor 1 drives the connecting shaft 31 to rotate, thereby driving the rotating drum 3 to rotate. As the rotating drum 3 rotates, the through port 2 35 on its outer side is aligned with the through port 1 21 on the upper side of the circular shell 2 in sequence, so that the seeds in the storage box 71 are evenly distributed to the four storage components 4. The storage component 4 in each storage chamber 36 works, and the seeds fall into the disinfection chamber formed by the connecting plate 41 and the two baffles 2 42;

[0056] Step 2: When the rotating shaft 72 rotates under the drive of the motor 2 74, the synchronous wheel 1 75 fixed thereon rotates accordingly. Through the transmission of the synchronous belt 78, the synchronous wheel 2 85 is driven to rotate, thereby rotating the driving shaft 83. The gear 2 84 and the synchronous wheel 2 85 at both ends of the driving shaft 83 rotate synchronously. The gear 2 84 meshes with the gear 1 8, driving the gear 1 8 to rotate. The gear 1 8 meshes with the gear 3 92 on each rotating shaft 9, so that the rotating shaft 9 starts to rotate, and the eccentric wheel 91 fixed on the rotating shaft 9 also rotates accordingly. During the rotation process, the irregular shape of the eccentric wheel 91 will exert a periodic force on the connecting plate 41. Under the reset action of the spring 44, the connecting plate 41 is connected. The connecting plate 41 drives the two baffles 42 to move back and forth and generate vibration. During the feeding process of the seeds from the feed pipe 77 into the disinfection chamber, the inclined surface design of the upper surface of the connecting plate 41 forms an efficient synergy with the vibration. When the seeds are accumulated under the feed pipe 77, the accumulation state of the seeds caused by gravity is broken by the vibration, and the sliding and rolling ability of the seeds on the inclined surface is enhanced. Under the dual effects of vibration and inclined surface, the seeds can be quickly and evenly distributed in the disinfection chamber. After the seeds are evenly distributed, the metering pump 52 is started, and the medicine is transported to the infusion tube 5 under the action of the metering pump 52, and the seeds in each disinfection chamber are sprayed with the medicine for disinfection through the multiple nozzles 51 at the bottom end of the infusion tube 5.

[0057] Step 3: After the spraying of the agent is completed, the motor 1 continuously drives the connecting shaft 31, driving the drum 3 to rotate continuously. During the rotation process, the contact plate 38 on the outside of the drum 3 is always in close contact with the inner wall of the round shell 2. At the same time, the opening 1 21 is located on the upper surface of the round shell 2, effectively preventing the seeds from leaking into the round shell 2 during the rotation process. The rotation of the drum 3 causes the seeds to continuously roll in the disinfection chamber and be fully mixed with the agent, ensuring that the surface of the seeds can be evenly contacted with the disinfectant, thereby improving the disinfection effect;

[0058] Step 4: After the seeds in each disinfection chamber have been mixed for a period of time, the second motor 74 is started again to reverse it. At this time, the seeds in the receiving box 71 have all been distributed to each disinfection chamber, and the reversal of the rotating shaft 72 will not cause additional impact. The reversal of the rotating shaft 72 is driven by the synchronous belt 78, the synchronous wheel 1 75, the synchronous wheel 2 85, the drive shaft 83, the gear 2 84, the gear 1 8 and the gear 3 92, so that the rotating shaft 9 and the eccentric wheel 91 are also reversed. The reversal of the eccentric wheel 91 drives the connecting plate 41 and the two baffles 42 to reciprocate and vibrate again, further promoting the mixing of the seeds and the medicine, and ensuring the best disinfection effect.

[0059] The fifth step: when the unloading process begins, the motor 1 in the mounting seat 11 is started to drive the drum 3 to rotate so that the discharge port 2 37 at the drum 3 is accurately aligned with the discharge port 1 24 on the protective plate 23 of the round shell 2, and then the electric telescopic rod 61 is started, and the telescopic rod drives the baffle plate 62 to move upward and disengage from the discharge port 1 24, thereby removing the obstruction to the discharge channel. At this time, the connecting plate 41 and the two baffle plates 2 42 continue to reciprocate under the vibration generated by the reversal of the eccentric wheel 91, and the upper surface of the connecting plate 41 is inclined toward the discharge port 1 24. Under the dual action of gravity and vibration, the seeds in the disinfection chamber are smoothly discharged from the discharge port 2 37 and the discharge port 1 24. After the seeds in one disinfection chamber are discharged, the drum 3 continues to rotate to discharge the seeds in other disinfection chambers in turn, completing the entire disinfection process.

[0060] Step 6: The two baffles 42 are located between the two vertical plates 33, and their surfaces are closely fitted with the surfaces of the vertical plates 33. At the same time, the penetrating rod 43 movably penetrates the through-hole 34 on the vertical plate 33, which not only prevents the seeds from entering the accommodating cavity 36, but also limits the movement of the connecting plate 41, ensuring the stable operation of the accommodating component 4. The sealing plate 22 provided at the through-hole 21 cooperates with the infusion tube 5 and other components to effectively seal the disinfection cavity, preventing the volatilization of the medicine and the entry of external impurities, thereby ensuring the stability of the disinfection environment.

[0061] Step 7: The support rings 39 fixedly installed at both ends of the rotating drum 3 are respectively embedded in the annular grooves 25 on the inner walls of the round shell 2 on both sides, providing stable support and limiting for the rotating drum 3, ensuring stable rotation of the rotating drum 3.

Many modifications and variations will be apparent to those skilled in the art.
