Description

Technical Field

[0001] The utility model relates to the technical field of sterilization, in particular to a sterilization device for rice seeds. Background Art

[0002] Rice seeds may contain pathogens such as bacteria and mold. In order to inhibit pathogens and avoid outbreaks of rice diseases, the seeds need to be disinfected.

[0003] There are two ways to disinfect rice seeds: pesticide disinfection and hot water disinfection. Using hot water disinfection can avoid the production of large amounts of toxic substances and is more environmentally friendly. Hot water disinfection involves immersing rice seeds in 60-degree Celsius water for 10 minutes to kill a variety of pathogens in rice seeds. Rice seeds in net bags need to be constantly shaken when immersed in hot water to ensure full contact between the seeds and the hot water. The above operations often require manual labor and pose certain safety risks. Therefore, a rice seed sterilization device is needed to sterilize rice mechanically. Utility Model Content

[0004] The utility model aims to at least solve the problem in the prior art that shaking of rice seeds during hot water disinfection requires manual operation.

[0006] Preferred technical solution 1: The front and rear ends of the two groups of arc-shaped plates are in contact with the front and rear walls of the hot water tank respectively, so that when the rice seeds are sterilized with hot water, impurities in the seeds that overflow from the bag can be filtered and retained by the mesh plates.

[0007] Preferred technical solution two: A cleaning mechanism is provided on the top of the hot water tank, and the cleaning mechanism is used to clean the mesh plate when the table rises to the top of the hot water tank.

[0008] The cleaning scraper on the screen is pressed against the top of the U-shaped cleaning plate, and the cleaning scraper is pressed against the top of the U-shaped cleaning plate, so that the cleaning scraper can be pushed forward and cleaned by sliding the cleaning scraper along the cross frame.

[0009] Preferred technical solution four: a screw rod 1 is rotatably provided in the hot water tank, the table is sleeved on the screw rod 1 through a threaded hole, and a motor 2 connected to the screw rod 1 is provided on the hot water tank.

[0010] Preferred technical solution five: The hot water tank is provided with a motor 1, and the motor 1 is connected to the power shaft.

[0011] Preferred technical solution six: The bottom ends of the two groups of arc-shaped plates are both provided with convex ridges, and the setting of the convex ridges is used to limit the rotation angle of the screen plate.

[0012] The above structure enables this solution to have the following beneficial effects:

[0013] 1. The curved plate is used in conjunction with the mesh plate, power shaft, and contact parts to continuously shake the rice seeds during hot water sterilization, ensuring full contact between the seeds and the hot water, thus avoiding the safety risks of manual operation.

[0014] 2. Use curved plates, vertical plates and mesh plates to filter and collect impurities that overflow from the bags, avoiding direct discharge and clogging of water inlet and outlet pipes;

[0015] 3. Through the clever structural setting, the cleaning mechanism can be lowered when the mesh plate moves to the top of the hot water tank and come into contact with the mesh plate for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
