Description
Technical Field
[0001] This utility model relates to the field of agricultural engineering technology, and in particular to seed high-temperature sterilization equipment. Background Technology
[0002] In agricultural production and scientific research, the health status of seeds plays a crucial role in crop growth, yield, and quality. During harvesting, storage, and transportation, seeds are highly susceptible to contamination by microorganisms such as bacteria, fungi, and viruses. These microorganisms not only reduce seed germination rate and vigor but also cause various diseases during seed germination and crop growth, seriously affecting agricultural production efficiency. Traditional seed sterilization methods, such as chemical treatment, while effective to some extent, easily leave chemical residues, pollute the environment, and harm human health. Furthermore, long-term use can lead to drug resistance in microorganisms. On the other hand, some physical sterilization methods, such as ultraviolet irradiation, suffer from incomplete sterilization and are greatly affected by the angle and distance of irradiation. Against this backdrop, the development of efficient, environmentally friendly, and safe high-temperature seed sterilization equipment is urgently needed.
[0003] High-temperature seed sterilization equipment mainly consists of a sterilization chamber, heating components, control components, and an air circulation device. Taking dry heat sterilization equipment as an example, during operation, the heating components rapidly heat up, creating a high-temperature environment within the sterilization chamber. The air circulation device ensures uniform flow of hot air within the chamber, avoiding temperature dead zones. Seeds are placed inside, and under the high temperature, the proteins, nucleic acids, and other important components of microorganisms denature and decompose, thus achieving sterilization. In the case of moist heat sterilization equipment, the high-temperature steam generated by heating has stronger penetrating power, more effectively killing various harmful microorganisms on and inside the seed surface.
[0004] Currently, some high-temperature sterilization equipment has significant shortcomings when processing seeds. Due to the lack of an effective vibration step, seeds are prone to sticking together and clumping during the sterilization process. This not only hinders the full contact of steam with the seeds, resulting in a significant reduction in sterilization effect, but also poses a risk to subsequent sowing and growth due to poor seed condition. Therefore, high-temperature seed sterilization equipment is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high-temperature seed sterilization device, which aims to improve the problem that the existing technology lacks an effective vibration step, and that seeds are prone to sticking together and clumping during the sterilization process.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A high-temperature sterilization equipment for seeds includes a chamber, a reciprocating mechanism is provided inside the chamber, a plate frame is provided at the top of the reciprocating mechanism, and a scraping mechanism is provided inside the chamber.
[0008] The reciprocating mechanism includes a motor, the bottom end of which is fixedly connected to the inside of the housing. An eccentric wheel is fixedly connected to the drive end of the motor. A transmission rod is rotatably connected to the outside of the eccentric wheel. A sliding plate is rotatably connected to the top end of the transmission rod.

[0011] As a further description of the above technical solution:
[0012] The fixing block is externally fixedly connected to the inside of the housing, and the bottom end of the spring is fixedly connected to the inside of the fixing block;
[0013] As a further description of the above technical solution:
[0014] The sliding ring is slidably connected to the outside of the fixed block, and a support plate is fixedly connected to the inside of the plate frame;
[0015] As a further description of the above technical solution:
[0016] The scraping mechanism includes a second motor, which is externally fixedly connected to the top of the housing. A rotating rod is fixedly connected to the drive end of the second motor. Two transmission rods are rotatably connected to the bottom end of the rotating rod. A sliding plate is rotatably connected to the opposite side of each of the two transmission rods. A scraper is fixedly connected to the bottom end of each of the two sliding plates. A collection box is fixedly connected to the bottom end of each of the two scrapers.
[0017] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, when sterilizing seeds at high temperature, the operator places a tray filled with seeds into the frame, and the bottom of the tray is firmly supported by a support plate. After closing the rotating door, the heating unit built into the chamber starts working. At the same time, the motor is started to drive the eccentric wheel to rotate. The eccentric wheel drives the transmission rod, and through a specific transmission structure, the frame moves back and forth in the chamber via a sliding device. This process can vibrate the seeds in the tray. Through slight vibration and position change, the seeds are effectively prevented from sticking together and clumping, maintaining their loose state. This greatly promotes full contact between steam and seeds, which not only improves the sterilization effect, but also creates favorable conditions for subsequent seed processing and packaging. Furthermore, the buffer structure ensures the stability of the entire reciprocating motion.
[0025] 2. In this invention, during high-temperature sterilization of the chamber, water mist easily accumulates at the top, forming water droplets. These droplets can affect the seeds and interfere with the sterilization process. To address this, the operator periodically starts another motor. This motor drives a rotating rod to rotate, which in turn drives a transmission rod to slide a sliding plate within the chamber. This, in turn, causes a scraper to scrape the top of the chamber's interior. The scraped-off water droplets are collected in the collection box below, successfully preventing the adverse effects of water droplets on the seed sterilization process, ensuring a suitable sterilization environment, and guaranteeing the smooth progress of the seed sterilization work.

[0032] 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.
[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a high-temperature seed sterilization device, comprising a housing 1. The housing 1 serves as the main structure of the entire device, providing a relatively enclosed and controllable space for high-temperature seed sterilization. The internal space of the housing 1 is used to accommodate the seeds to be sterilized and various actuators. A reciprocating mechanism 2 is provided inside the housing 1. The reciprocating mechanism 2 plays a key role, enabling specific motion operations on the components where the seeds are placed.
[0034] The reciprocating mechanism 2 includes a motor 21, the bottom of which is firmly fixed to the inside of the housing 1. The motor 21 serves as a power source, providing driving force for a series of subsequent movements. When the motor 21 starts operating, it can stably output power. An eccentric wheel 22 is fixedly connected to the drive end of the motor 21. Driven by the motor 21, the eccentric wheel 22 begins to rotate. Due to its eccentric structural design, a transmission rod 23 is rotatably connected to the outside of the eccentric wheel 22. As the eccentric wheel 22 rotates, its eccentric characteristic causes the transmission rod 23 to be continuously pushed and pulled. A sliding plate 24 is rotatably connected to the top of the transmission rod 23, serving as a connecting transmission... The function of rod 23 and plate frame 4 is as follows: when the transmission rod 23 rotates, it transmits the motion to the plate frame 4 through the sliding plate 24. The top of the sliding plate 24 is fixedly connected to the bottom of the plate frame 4. This connection method allows the plate frame 4 to move with the movement of the sliding plate 24. The bottom of the sliding plate 24 is fixedly connected to the connecting column 25. When the sliding plate 24 moves, the connecting column 25 will move synchronously. The connecting column 25 is provided with a buffer component 26 on the outside. The buffer component 26 is used to ensure the stability and smoothness of the entire reciprocating motion process. The plate frame 4 is fixedly connected to the outside of the sliding block 27. The sliding block 27 plays a key guiding role in the subsequent movement.
[0035] The buffer assembly 26 includes a fixed block 263, which is internally slidably connected to the outside of the connecting post 25. The connecting post 25 can slide smoothly inside the fixed block 263, ensuring the continuity of movement. A sliding ring 262 is fixedly connected to the bottom end of the connecting post 25. The sliding ring 262 moves synchronously with the connecting post 25. A spring 261 with good elasticity is fixedly connected to the bottom end of the sliding ring 262. The outside of the fixed block 263 is fixedly connected to the inside of the housing 1, so the fixed block 263 is stably fixed inside the housing 1. The bottom end of the spring 261 is fixedly connected to the inside of the fixed block 263. When the connecting post 25 moves with the sliding plate... 4. During lifting and lowering, the connecting column 25 drives the sliding ring 262 to slide inside the fixed block 263. The spring 261 will buffer and push the sliding ring 262 as it slides inside the fixed block 263. During the lifting of the plate frame 4, the spring 261 will be compressed to buffer and prevent the impact caused by excessive lifting speed. When the plate frame 4 is lowered, the spring 261 will release elastic potential energy to generate an upward thrust on the sliding ring 262, which will help the plate frame 4 to descend smoothly, thereby ensuring the stable operation of the reciprocating mechanism 2. The plate frame 4 is fixedly connected to a support plate 5, which is mainly used to support the items placed inside the plate frame 4.
[0036] Reference Figure 1 , Figure 2 and Figure 4The scraping mechanism 3 includes a second motor 31, which is externally fixed to the top of the housing 1. The second motor 31 serves as the power source for the scraping mechanism 3, providing the necessary power for the scraping action. A rotating rod 32 is fixedly connected to the drive end of the second motor 31. When the second motor 31 starts, it drives the rotating rod 32 to rotate. The rotation of the rotating rod 32 is the initial power transmission link for a series of subsequent scraping actions. Two transmission rods 33 are rotatably connected to the bottom end of the rotating rod 32. The rotation of the rotating rod 32 drives the two transmission rods 33 to move accordingly. Sliding plates 34 are rotatably connected to the opposite sides of the two transmission rods 33. The movement of the transmission rods 33 allows the sliding plates 34 to slide inside the housing 1. Scraper blades 35 are fixedly connected to the bottom ends of the two sliding plates 34. The sliding of the sliding plates 34 drives the scraper blades 35 to move together. The scraper blades 35 are used to scrape the top of the inside of the housing 1. A collection box 36 is fixedly connected to the bottom ends of the two scraper blades 35.
[0037] When the scraper 35 scrapes away the water droplets that condense at the top of the inner wall of the box 1, the water droplets fall directly into the collection box 36, achieving effective collection of the water droplets. The external sliding plate 34 is slidably connected to the inside of the box 1, ensuring that the sliding plate 34 can slide smoothly in a specific direction inside the box 1. The external sliding plate 35 is slidably connected to the top of the inner wall of the box 1, ensuring that the scraper 35 can closely fit the top of the inner wall of the box 1 to perform the scraping action, leaving no dead corners for cleaning. The inside of the box 1 is provided with a sliding groove, and the external sliding block 27 is slidably connected to... Inside the chute, the cooperation between the chute and the sliding block 27 ensures that the plate frame 4 has a stable movement trajectory during reciprocating lifting and lowering, preventing deviation and ensuring smooth lifting and lowering of the plate frame 4. The front end of the box 1 is rotatably connected to a rotating door 7, which facilitates the operator to place the tray filled with seeds on the plate frame 4 and remove the tray after sterilization. The top of the box 1 is fixedly connected to an alarm 6, which can sound an alarm when the equipment malfunctions, such as excessive temperature or equipment failure, to remind the operator to deal with it in time.
[0038] Working principle: When the operator needs to sterilize the seeds at high temperature, the tray filled with seeds is placed inside the rack 4. The support plate 5 will support the bottom of the tray. After the tray is placed, the rotating door 7 is closed. The heating unit built into the box 1 will perform high-temperature sterilization on the seeds. The operator can start motor 21, which drives eccentric wheel 22 to rotate. Eccentric wheel 22 drives transmission rod 23 to rotate. When transmission rod 23 rotates, it drives sliding plate 24, causing plate frame 4 to reciprocate up and down inside box 1 via sliding block 27. This vibrates the seeds inside the tray. The reciprocating up and down of plate frame 4 can prevent seeds from sticking together or clumping through slight vibration and position changes, keeping the seeds loose and facilitating full contact between steam and seeds. It also facilitates subsequent seed processing and packaging. While sliding plate 24 is rising and falling, connecting column 25 slides inside fixed block 263 via sliding ring 262. Spring 261 buffers and pushes sliding ring 262 as it slides inside fixed block 263, thus ensuring the stable operation of reciprocating mechanism 2.
[0039] When the chamber 1 is sterilized at high temperature, water mist will accumulate at the top inside the chamber 1. The condensed water droplets will affect the sterilization of the seeds. The operator can periodically start the motor 2 31, which will drive the rotating rod 32 to rotate. The rotation of the rotating rod 32 will cause the transmission rod 2 33 to drive the sliding plate 2 34 to slide inside the chamber 1. As a result, the scraper 35 scrapes the top inside the chamber 1. The scraped water droplets will be collected inside the collection box 36, effectively preventing the water droplets from affecting the sterilization of the seeds.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
