Description

Technical Field

[0001] This utility model belongs to the technical field of seed disinfection equipment, specifically a vegetable seed disinfection treatment device. Background Technology

[0002] Vegetable seeds need to be disinfected before sowing to kill pathogens such as bacteria and fungi on the seed surface, reduce seedling diseases, and improve seed germination and seedling survival rates. Ultraviolet (UV) sterilization is widely used in vegetable seed disinfection due to its advantages of no chemical residue and ease of operation. However, existing vegetable seed disinfection equipment lacks the ability to rotate the seeds during use. Seeds are laid flat on the support device for sterilization, which easily leads to stacking. This results in seeds in the stacked areas not being exposed to UV light, creating sterilization dead zones, affecting the sterilization effect, and reducing the applicability of the vegetable seed disinfection equipment. Therefore, we propose a vegetable seed disinfection device to solve the above problems. Utility Model Content

[0003] To address the above technical problems, this utility model provides a vegetable seed disinfection and treatment device to solve the problems of lack of reciprocating turning ability and inability to collect dust.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a vegetable seed disinfection treatment device, including a device shell, an end cover hinged to the top of the device shell, an ultraviolet germicidal lamp fixedly connected to the bottom surface of the end cover, a support frame slidably connected inside the device shell, a screen fixedly connected inside the support frame, a support plate fixedly connected to the inner side wall of the device shell, a servo motor fixedly connected to the side of the support plate, an eccentric wheel fixedly connected to the shaft of the servo motor passing through the support plate, a connecting rod rotatably connected to the eccentric wheel, a push rod rotatably connected to the end of the connecting rod, a support block fixedly connected to the support plate, the push rod passing through the support block and slidably connected to it, the end of the push rod fixedly connected to the support frame, an auxiliary block fixedly connected to the inside of the device shell on the opposite side of the support plate, a connecting block fixedly connected to the support frame on the same side, a plurality of return springs fixedly connected to the auxiliary block, and the other end of the return springs fixedly connected to the connecting block.

[0005] Furthermore, an auxiliary handle is fixedly connected to the end cap, and an anti-slip sleeve is fitted onto the auxiliary handle.

[0006] Furthermore, a support column is fixedly connected to the bottom of the device housing, and a stabilizing ring is fixedly connected to the bottom of the support column.

[0007] Furthermore, a collection box is slidably connected inside the housing of the device, a filter plate is fixedly connected inside the collection box, and a miniature negative pressure pump is fixedly connected to the side of the collection box.

[0008] Furthermore, a stabilizing block is fixedly connected to the bottom of the collection box, and the stabilizing block is slidably connected to the bottom of the device housing. A pull handle is fixedly connected to the side of the collection box.

[0009] Furthermore, a guide rail is fixedly connected inside the device housing, and a movable block is fixedly connected to the support frame twice, with the movable block slidably connected to the guide rail.

[0010] Furthermore, an auxiliary bearing is embedded inside the support plate, and the eccentric wheel passes through the interior of the auxiliary bearing.

[0011] This utility model has the following advantages compared with the prior art:

[0012] This invention features a servo motor and an eccentric wheel, which drive a push rod to make the carrying frame reciprocate, continuously turning the seeds inside. This avoids the problem of localized areas not being exposed to ultraviolet light due to seed stacking in traditional equipment, ensuring that each seed receives uniform irradiation from the ultraviolet sterilization lamp. This significantly improves sterilization coverage and thoroughness, effectively reducing the residual rate of pathogens carried by the seeds, thus reducing the risk of disease in subsequent seedling cultivation and enhancing the applicability of vegetable seed disinfection equipment. A reset spring buffers and assists in the reset of the carrying frame, while guide rails and moving blocks maintain stable movement of the carrying frame to prevent it from tipping over. A micro negative pressure pump generates negative pressure to adsorb dust from the seed surface and guide it into the collection box. Pulling the handle allows for easy removal of the collection box for cleaning and maintenance. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1-4 The vegetable seed disinfection equipment shown includes a housing 1, an end cap 2 hinged to the top of the housing 1, an ultraviolet germicidal lamp 3 fixedly connected to the bottom of the end cap 2, a support frame 4 slidably connected inside the housing 1, a screen 5 fixedly connected inside the support frame 4, a support plate 6 fixedly connected to the inner side wall of the housing 1, a servo motor 8 fixedly connected to the side of the support plate 6, an eccentric wheel 7 fixedly connected to the shaft of the servo motor 8 passing through the support plate 6, a connecting rod 11 rotatably connected to the eccentric wheel 7, a push rod 10 rotatably connected to the end of the connecting rod 11, a support block 9 fixedly connected to the support plate 6, the push rod 10 passing through the support block 9 and slidably connected to it, and the end of the push rod 10 fixedly connected to the support frame 4. An auxiliary block 24 is fixedly connected inside the housing 1 on the opposite side of the support plate 6, a connecting block 25 is fixedly connected to the support frame 4 on the same side, a plurality of return springs 26 are fixedly connected to the auxiliary block 24, and the other end of the return springs 26 is fixedly connected to the connecting block 25.

[0020] To facilitate opening the end cover 2, an auxiliary handle 12 is fixedly connected to the end cover 2. An anti-slip sleeve 13 is fitted on the auxiliary handle 12. The auxiliary handle 12 provides a force point for opening and closing the end cover 2. The anti-slip sleeve 13 increases the friction of the hand, avoids slipping during operation, and improves the convenience and safety of use.

[0021] For stable support, a support column 14 is fixedly connected to the bottom of the equipment shell 1, and a stabilizing ring 15 is fixedly connected to the bottom of the support column 14. The support column 14 supports the overall weight of the equipment, and the stabilizing ring 15 increases the force-bearing area between the support column 14 and the contact surface, preventing the equipment from tipping over and ensuring the stability of the equipment during the disinfection process.

[0022] To facilitate the removal of floating dust, a collection box 16 is slidably connected inside the outer casing 1 of the equipment. A filter plate 17 is fixedly connected inside the collection box 16. A miniature negative pressure pump 19 is fixedly connected to the side of the collection box 16. The miniature negative pressure pump 19 generates negative pressure, adsorbs the dust on the surface of the seeds and introduces it into the collection box 16. Pulling the handle 20 makes it easy to remove the collection box 16 for cleaning and maintenance.

[0023] To ensure stable dust collection, a stabilizing block 18 is fixedly connected to the bottom of the collection box 16. The stabilizing block 18 is slidably connected to the bottom of the equipment housing 1. A pull handle 20 is fixedly connected to the side of the collection box 16. The stabilizing block 18 restricts the sliding trajectory of the collection box 16, preventing the collection box 16 from shaking or shifting inside the equipment housing 1, and ensuring a stable dust collection process.

[0024] To facilitate the stable movement of the support frame 4, a guide rail 21 is fixedly connected inside the equipment housing 1. The support frame 4 is fixedly connected to two moving blocks 22. The moving blocks 22 are slidably connected to the guide rail 21. The guide rail 21 provides a sliding track for the moving blocks 22. The moving blocks 22 are fixedly connected to the support frame 4, guiding the support frame 4 to make smooth reciprocating linear motion and avoiding jamming or deviation during movement.

[0025] To facilitate the smooth rotation of the eccentric wheel 7, an auxiliary bearing 23 is embedded inside the support plate 6. The eccentric wheel 7 passes through the auxiliary bearing 23, which reduces the frictional resistance between the eccentric wheel 7 and the support plate 6 when the eccentric wheel 7 rotates, reduces component wear, and improves the smoothness of rotation.

[0026] The specific working process of this utility model is as follows:

[0027] In use, the staff opens the end cap 2 through the auxiliary handle 12 on the end cap 2, and evenly spreads the vegetable seeds to be disinfected on the screen 5 inside the carrying frame 4, ensuring that the initial distribution of the seeds is relatively loose. Then, the end cap 2 is closed, and the ultraviolet sterilization lamp 3 and servo motor 8 are turned on. The ultraviolet sterilization lamp 3 emits ultraviolet light to sterilize the seeds in the carrying frame 4. The servo motor 8 drives the eccentric wheel 7 at the output end to rotate. The eccentric wheel 7 pulls the push rod 10 through the connecting rod 11, so that the push rod 10 drives the support block 9 to slide left and right in the support plate 6, thereby pushing the carrying frame 4 to move to one side. At this time, the carrying frame 4 compresses the return spring 26 in the auxiliary block 24 through the connecting block 25. When the eccentric wheel 7 rotates to a specific angle, the return spring 26 rebounds and pushes the connecting block 25, so that the carrying frame 4 moves to the other side. At the same time, the carrying frame 4 slides in the guide rail 21 through the moving block 22 to maintain stability, realizing the reciprocating motion of the carrying frame 4 and driving the seeds to continuously turn.

[0028] During the disinfection and turning process, the micro negative pressure pump 19 is started simultaneously. The operation of the micro negative pressure pump 19 creates a negative pressure in the collection box 16. The air inside the equipment shell 1 carries dust, debris and other impurities from the seed surface and enters the collection box 16 through the pores of the screen 5. The impurities are intercepted by the filter plate 17 inside the collection box 16, while the clean air is discharged through the micro negative pressure pump 19, thus achieving seed cleaning and impurity collection. After the disinfection work is completed, the ultraviolet germicidal lamp 3, the servo motor 8 and the micro negative pressure pump 19 are turned off in sequence. The end cover 2 is opened through the auxiliary handle 12, and the disinfected seeds are taken out from the carrier frame 4. Then, the collection box 16 is pulled out by pulling the handle 20 to clean the impurities inside the collection box 16. If the filter plate 17 is blocked or damaged, it can be disassembled and replaced. After cleaning, the collection box 16 is reset to the inside of the equipment shell 1 through the stabilizing block 18, completing the entire disinfection process.
