Technical Field

[0001] This utility model relates to the field of seed disinfection technology, specifically to a drum-type dry heat disinfection device for seeds. Background Technology

[0002] Seed dry heat sterilization is an agricultural technique that kills pathogens in a high-temperature, dry heat environment. By destroying the structure of pathogens through high temperatures, it achieves a sterilization effect and is often used to treat stubborn diseases that are difficult to kill by conventional disinfection methods, thus ensuring the health of seeds.

[0003] Seed dry heat sterilization requires specific temperature and humidity conditions, necessitating specialized equipment (such as a constant temperature chamber) to set the temperature to 70°C and the humidity to 20%, and to continue treatment for a week. In conventional static dry heat sterilization processes, the seeds are piled together, hindering sufficient contact with the environment and affecting the quality of the sterilization. Furthermore, such dry heat sterilization devices have low throughput, poor uniformity, and poor process control repeatability, making industrial application impossible. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a drum-type dry heat sterilization device for seeds that can quickly and in batches perform high-temperature sterilization of seeds.

[0026] like Figures 1-6 As shown, this utility model discloses a drum-type dry heat sterilization device for seeds, which includes a housing 1, a drum assembly 2, an air supply assembly 3, and a dehumidification assembly 4.

[0027] The box body 1 is equipped with a disinfection chamber 11, and the box body 1 is equipped with a door 12 that can open or close the disinfection chamber 11. The roller assembly 2 consists of three evenly arranged rollers in the disinfection chamber 11, which are used to hold the seeds and drive the seeds to rotate.

[0028] The roller assembly 2 includes a movable support 21, rollers 22, and a drive unit 23. Rollers 24 are connected to the bottom of the movable support 21. There are two rollers 22, arranged vertically and rotatably connected to the movable support 21. There are also two drive units 23 (e.g., motors), each connected to a corresponding roller 22 for driving its rotation. The front face of each roller 22 is meshed to facilitate the entry of hot air into the roller 22.

[0029] Two drive units 23 are fixedly connected to the rear wall of the housing 1, and their output shafts extend into the disinfection chamber 11 and are provided with a first snap-fit ​​part 231; the end of the rotating shaft of the roller 22 facing the drive unit 23 is provided with a second snap-fit ​​part 221 that matches the first snap-fit ​​part 231, and the first snap-fit ​​part 231 is detachably inserted into the corresponding second snap-fit ​​part 221.

[0030] The roller 22 is too heavy, so it is mounted on the movable bracket 21 to facilitate the user's pulling of the roller 22 out of the disinfection chamber 11. The drive unit 23 and the roller 22 are connected by a quick-release mechanism. When pulling the roller 22 out of the disinfection chamber 11, simply pull the movable bracket 21 horizontally without any additional disassembly. When connecting the drive unit 23 and the roller 22, simply push the movable bracket 21 into the disinfection chamber 11 so that the first locking part 231 is inserted into the second locking part 221. To prevent misalignment between the first locking part 231 and the second locking part 221, a guide groove is provided on the bottom wall of the disinfection chamber 11. The roller 24 on the movable bracket 21 is slidably connected in the guide groove, which can play a guiding role.

[0031] The end face of the roller 22 facing the door 12 is provided with three feed ports 222 that communicate with its inner cavity. A cover plate 223 is rotatably connected to the feed port 222. The door 12 is provided with a through hole 121 at the position corresponding to the movement trajectory of the feed port 222. The through hole 121 is used for the injection pipe to pass through and be inserted into the feed port 222. The box body 1 is also provided with an exhaust fan, which is connected to the disinfection chamber 11 and is used to evacuate the disinfection chamber 11.

[0032] During feeding, first close the box door 12 (since the feed inlet 222 will rotate with the roller 22, before closing the box door 12, ensure that the feed inlet 222 is rotated into place to avoid misalignment with the through hole 121). Connect one end of the feeding pipe to the material box, and pass the other end through the through hole 121 and insert it into the feed inlet 222. Then turn on the exhaust fan to evacuate the sterilization chamber 11. A negative pressure is generated in the sterilization chamber 11, and the roller 22, located in the sterilization chamber 11, will also generate a negative pressure. Therefore, the seeds will be sucked into the sterilization chamber 11 through the feeding pipe, completing the feeding. After the seeds have been dry-heat sterilized, the box door 12 can be opened, and then the seeds can be directly sucked out through the feed inlet 222 by the suction machine, completing the discharge.

[0033] The air supply assembly 3 includes a blower 31 and an electric heating plate 32. The housing 1 is provided with an air supply channel 13 and an electrical compartment 14 connected to the air supply channel 13.

The blower 31 and the electric heating plate 32 are arranged in the electrical compartment 14, and the electric heating plate 32 is arranged near the air supply channel 13 for supplying hot air into the disinfection chamber 11.

[0034] Inside the disinfection chamber 11, a guide plate 113 is provided between two adjacent roller groups 2. The guide plate 113 extends in the vertical direction and the two adjacent guide plates 113 are staggered.

[0035] The misaligned baffle 113 can guide the hot air in the disinfection chamber 11, so that the hot air in the disinfection chamber 11 circulates up and down, thereby ensuring the temperature in the disinfection chamber 11 is balanced.

[0036] The disinfection chamber 11 is also equipped with a temperature and humidity sensor, which transmits temperature and humidity signals to the PLC system. The PLC system controls the operation rhythm of the electric heating plate 32 and the dehumidification component 4, thereby achieving precise temperature and humidity control and avoiding damage to the seeds caused by excessive temperature or humidity.

[0037] The dehumidification component 4 includes a dehumidifier, which is installed inside the electrical compartment 14 to remove moisture from the air and reduce the humidity inside the disinfection chamber 11. A drain hole is also provided on the side wall of the housing 1 near the dehumidifier to facilitate the discharge of moisture. The dehumidifier is prior art and will not be described in detail here.

[0038] This invention features a disinfection chamber 11 within the housing 1. Hot air is supplied to the disinfection chamber 11 via an air supply assembly 3, and the humidity within the disinfection chamber 11 is controlled by a dehumidification assembly 4, ensuring that the environment within the disinfection chamber 11 meets the requirements for dry heat disinfection of seeds.
