[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-4 This utility model provides a disinfection and sterilization device for sorghum seeds, comprising: Frame 1, on which a control system 2, a housing 3 and a liquid supply mechanism are installed; the top of the housing 3 is detachably connected to a feed end cover 4, and the bottom is equipped with a drain assembly; the liquid supply mechanism is connected to the housing 3. The driver component is installed on frame 1; The cylinder 5 is installed inside the box 3. Several through holes 6 are opened on the cylinder 5. A screw conveyor assembly is rotatably connected inside the cylinder 5. A feed inlet 7 is provided on one side of the top surface of the cylinder 5. The feed inlet 7 is located directly below the feed end cover 4. The mixing and stirring assembly is rotatably connected inside the housing 3 and located below the cylinder 5; Among them, a discharge assembly is installed on the housing 3, and the discharge assembly is connected to the discharge end of the screw conveyor assembly; the mixing and stirring assembly and the screw conveyor assembly are both connected to the output shaft of the drive assembly; the discharge assembly, the liquid supply mechanism, the liquid discharge assembly and the drive assembly are all electrically connected to the control system 2. With this configuration, the disinfectant can fully penetrate into the seed pile through several through holes 6 on the cylinder 5. At the same time, the spiral conveying component agitates the seeds during the seed transport process, and together with the mixing component below, it mixes the disinfectant evenly, effectively avoiding blind spots in disinfection and ensuring full contact between the seeds and the disinfectant. This significantly improves the uniformity and thoroughness of disinfection. The control system 2 controls the output power of the drive component, thereby adjusting the rotation speed of the spiral conveying component to precisely control the contact time between the seeds and the disinfectant. This reduces excessive stimulation of the seeds by chemical agents, improves disinfection efficiency, and ensures the germination rate and vigor of sorghum seeds. This utility model integrates multiple functional modules such as liquid supply, material conveying, stirring, material discharge, and liquid drainage, all of which are electrically connected through the control system 2. Operators can precisely control parameters such as the liquid supply volume of the liquid supply mechanism, the running speed of the drive component, and the start and stop of the material discharge component through the control system, without the need for frequent manual intervention, which greatly reduces labor intensity. The spiral conveying component has both conveying and stirring functions, which effectively improves the processing efficiency of sorghum seeds.

[0020] The solution has been further optimized, and the liquid supply mechanism includes: Water tank 8 is mounted on frame 1; Liquid inlet pipe 9, one end of which is connected to water tank 8, and the other end of which is connected to tank body 3; Liquid pump 10 is installed on inlet pipe 9; The first solenoid valve 11 is installed on the inlet pipe 9; In this embodiment, the liquid pump 10 and the first solenoid valve 11 are both electrically connected to the control system 2. In this embodiment, the control system 2 adopts a PLC or a microcontroller. When in use, the control system 2 controls the liquid pump 10 and the first solenoid valve 11 to open. The liquid pump 10 delivers the disinfectant in the water tank 8 to the box body 3 to provide a stable disinfectant environment for seed disinfection.

[0021] The further optimized scheme includes a drive component including a motor 12 electrically connected to the control system 2. The motor 12 is mounted on the frame 1 via a motor mount. A first pulley 13 is mounted on the output shaft of the motor 12. A second pulley 14 is mounted on one end of the screw conveyor component. A third pulley 15 is mounted on one end of the mixing and stirring component. A first synchronous belt is fitted over the first pulley 13 and the second pulley 14. A second synchronous belt is fitted over the second pulley 14 and the third pulley 15. The control system 2 controls the motor 12 to start, and the output shaft of the motor 12 drives the first pulley 13 to rotate. The first pulley 13 transmits power to the second pulley 14 through the first synchronous belt, so that the second pulley 14 drives the spiral conveying assembly to rotate, realizing the conveying and tumbling of seeds. At the same time, the second pulley 14, as an intermediate transmission wheel, transmits power to the third pulley 15 through the second synchronous belt. The third pulley 15 then drives the mixing and stirring assembly to rotate, completing the stirring and mixing of the disinfectant.

[0022] The solution is further optimized so that the mixing and stirring assembly includes a first rotating shaft 16 rotatably connected to the inner wall of the housing 3, a third pulley 15 located outside the housing 3, and the third pulley 15 is installed at one end of the first rotating shaft 16. A number of equally spaced stirring blades 17 are installed on the first rotating shaft 16. A number of inclined turbulent flow grooves 18 are opened on the stirring blades 17. The first rotating shaft 16 is located below the cylinder 5. During the rotation of the stirring blade 17, it generates a lateral pushing force on the disinfectant in the box 3. The inclined turbulent flow channel 18 on the stirring blade 17 allows some of the disinfectant to flow along the inclined direction of the turbulent flow channel 18 during stirring. The crisscrossing fluid movement greatly improves the uniformity of the disinfectant, avoids the accumulation of easily precipitated components in the disinfectant at the bottom of the box 3, ensures the uniform concentration of the disinfectant in the box 3, and thus ensures the uniform concentration of the disinfectant that permeates into the seed pile through the through hole 6 of the cylinder 5, thereby improving the consistency of sorghum seed disinfection.

[0023] Further optimization of the scheme: the screw conveyor assembly includes a second rotating shaft 19 rotatably connected to the inner side wall of the housing 3, a second pulley 14 located outside the housing 3, and the second pulley 14 installed at one end of the second rotating shaft 19; the second rotating shaft 19 is located inside the cylinder 5, and screw conveyor blades 20 are installed on the second rotating shaft 19; The discharge assembly includes a discharge port 21, a discharge blade 22, and an arc-shaped discharge baffle 23. The discharge blade 22 is installed at the end of the second rotating shaft 19 away from the second pulley 14. The cylinder 5 has an opening at the end away from the feed inlet 7. The arc-shaped discharge baffle 23 is fixedly connected to the inner wall of the box 3 and is located below the opening. The discharge blade 22 is slidably connected to the inner wall of the arc-shaped discharge baffle 23. The discharge port 21 is installed on the side wall of the box 3. An electrically controlled discharge valve that is electrically connected to the control system 2 is installed inside the discharge port 21. The discharge port 21 is located on one side of the top surface of the arc-shaped discharge baffle 23. When the drive assembly drives the second shaft 19 to rotate via the second pulley 14, the second shaft 19 drives the spiral conveying blades 20 to rotate inside the cylinder 5, pushing the seeds to move slowly from the end near the inlet 7 to the outlet end, thus achieving continuous seed conveying. At the same time, during the conveying process, the spiral surface of the spiral conveying blades 20 will generate an upward lifting force and a lateral tumbling force on the seeds, causing the seeds to continuously tumble and stir inside the cylinder 5, avoiding seed accumulation and forming dead corners, and ensuring that the sorghum seeds are in full contact with the disinfectant that penetrates through the through-holes 6 of the cylinder 5, thereby improving the uniformity of disinfection. When the screw conveyor assembly delivers the seeds to the discharge end opening of the cylinder 5, the seeds fall from the opening of the cylinder 5 into the arc-shaped discharge baffle 23 under the thrust of the screw conveyor blades 20. At this time, the discharge blades 22, which rotate synchronously with the second rotating shaft 19, push the sorghum seeds into the discharge port 21. The control system 2 controls the opening and closing of the electrically controlled discharge valve. When the electrically controlled discharge valve is opened, the disinfectant is discharged first, and then the sorghum seeds are discharged from the equipment through the discharge port 21. When it is necessary to pause the discharge, the control system 2 closes the electrically controlled discharge valve, and the discharge blades 22 temporarily store the seeds in the arc-shaped discharge baffle 23. The seeds will continue to be discharged after the valve is reopened, thus achieving controllability of the discharge.

[0024] The solution is further optimized by including a drain pipe 24 installed at the bottom of the housing 3, and a second solenoid valve 25 electrically connected to the control system 2 installed inside the drain pipe 24.

[0025] The design has been further optimized by installing a water level observation window 26 on water tank 8.

[0026] To further optimize the design, two parallel walking wheels 27 are installed on one side of the bottom of frame 1.
