Description

Technical Field

[0001] This utility model relates to the field of sweet potato virus-free culture technology, specifically to an integrated device for disinfecting and sterilizing stem tips for sweet potato virus-free culture. Background Technology

[0002] Sweet potato is a widely distributed, high-yielding root crop, and an important food, feed, and industrial raw material. It is widely cultivated in tropical regions of Asia, Africa, and Latin America. my country is one of the major sweet potato producing countries. In 2015, its planting area reached 3.43 million hectares, accounting for more than 34% of the world's total sweet potato planting area. Its total fresh sweet potato production was 1.2 x 10⁻⁶ tons, accounting for 66% of the world's total sweet potato production, ranking first in the world. Hubei Province also has nearly 200,000 hectares. Sweet potato is a crop that reproduces using tubers and vines, making it susceptible to viral diseases. Viral diseases often lead to variety degeneration, reduced yield, and deteriorated quality, affecting not only the preservation of sweet potato varietal resources and the breeding of new varieties, but also the marketability and production efficiency of sweet potatoes. Early-stage stem tip disinfection and sterilization relied on multiple manual steps (washing, chemical disinfection), which was time-consuming and resulted in poor sterilization and disinfection effects.

[0003] Searching existing technologies, CN221152359U discloses a sweet potato virus-free seedling cultivation chamber. It includes a cultivation chamber body (1), a ventilation structure, a lighting structure, a humidity control structure, and a shelf (4). The ventilation structure includes an intake fan (303), an exhaust fan (301), and a filter (3). The intake fan (303) has a rotating shaft fixedly connected to a first motor (304), and the exhaust fan (301) has a rotating shaft fixedly connected to a second motor (305). The filter (3) is located on the outside of the cultivation chamber body (1) and fixedly connected to the intake fan (303). The exhaust fan (301) is located on the other side of the cultivation chamber body (1) facing the intake fan (303). The lighting structure includes an LED light (2) and a base, and is fixed to the top inside the cultivation chamber body (1).

[0004] The filter, which is fixedly connected to the intake fan in the comparative document, filters out impurities in the outer air before it enters the culture chamber during ventilation. At the same time, the isolation cover on the shelf ensures that the virus-free seedlings on the shelf will not be affected during the ventilation process, thus ensuring that the virus-free seedlings in cultivation will not be affected during the entire ventilation process. However, it cannot disinfect and sterilize the seedlings, resulting in poor processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an integrated device for disinfecting and sterilizing stem tips for sweet potato virus-free culture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a water bath chamber and a disinfection chamber.

A drive device 5 is located at one end of the water bath chamber 1, and a drive motor 6 is located at the lower end of the drive device 5. The disinfection chamber 2 is meshed with one end of the drive device 5. A shaking device 7 is located at the upper end of the disinfection chamber 2, and the shaking device 7 is connected to the drive device 5. The drive device 5 can drive the water bath chamber 1 to rotate and the disinfection chamber 2 to disinfect.

[0016] The driving device 5 includes a turntable 8, the lower end of which is connected to a drive motor 6. A drive disk 9 is fixedly connected to the output end of the drive motor 6, and the drive disk 9 contacts the turntable 8. Multiple internal linkage teeth 10 are fixedly connected inside the turntable 8, and transmission gears 11 mesh with the internal linkage teeth 10. One end of the transmission gear 11 meshes with a drive wheel 12, which drives the water bath 1. The turntable 8 can drive the transmission gear 11 through the linkage teeth, thereby causing the water bath 1 to rotate.

[0017] A tray 13 is detachably connected to the rotating wheel 3. The tray 13 has multiple mounting holes, into which a stem tip box 14 is fitted. One end of the rotating wheel 3 is fixedly connected to the drive wheel 12. The stem tip box 14 can be placed and fixed within the mounting holes.

[0018] The turntable 8 has an outer linkage tooth 15 on its outer side, and a pulley 16 is meshed on the outer linkage tooth 15.

When the drive motor 6 operates, it drives the turntable 8 to rotate, which in turn causes the inner linkage gear 10 and outer linkage gear 15 on the turntable 8 to mesh with the pulley 16 or drive wheel 12, driving the water bath chamber 1 or the disinfection chamber 2 to rotate. During one rotation of the turntable 8, when the water bath chamber 1 rotates, the disinfection chamber 2 is stopped; when the disinfection chamber 2 rotates, the water bath chamber 1 is stopped. The existing disinfection process is as follows: Water bath chamber 1: automatically tumbles, sprays and automatically absorbs 70% alcohol, cleans for 30 seconds, then pauses; Disinfection chamber: every 30 seconds, automatically shakes for 5 seconds and uses 2% sodium hypochlorite for disinfection. Therefore, by setting the rotation time of the turntable 8 to 35 seconds per revolution, and distributing the inner linkage gear 10 and outer linkage gear 15 in a 6:1 ratio, it is possible to achieve a seamless transition from water bath chamber 1 spraying alcohol for 30 seconds, pausing for 5 seconds, followed by the disinfection chamber 2 shaking for 5 seconds, and then the disinfection chamber 2 pausing for 30 seconds. This reduces the need for frequent motor starts and stops, thereby reducing wear and extending the motor's lifespan.
