The agricultural product cleaning and sterilization machine is a device used to improve food hygiene and safety. It rinses agricultural products with clean water and sterilizes and dries the cleaned agricultural products to ensure the hygiene and safety of agricultural products and facilitate subsequent agricultural product processing operations.

[0003] However, the existing agricultural product cleaning and sterilization machines have the following shortcomings. Since there will be a lot of impurities and sediment on the agricultural products, these sediments and impurities need to be discharged after the agricultural product cleaning and sterilization machines clean the agricultural products. However, some of the sediments and impurities are large in particles, and they are easily blocked by being discharged from the pipes for a long time. Therefore, a filter screen that blocks large particles of sediment or impurities is usually installed in the agricultural product cleaning and sterilization machine. After a long period of filtration, some sediment and impurities are easily stuck in the filter holes of the filter screen, which will affect the filtration efficiency. Therefore, the current agricultural product cleaning and sterilization machines need to be improved. Summary of the Invention

[0026] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , a fixing bracket 16 is connected to the inner wall of the box body 1 near the bottom of the filter screen plate 15, and an anti-blocking mechanism 7 is connected to one side of the fixing bracket 16, and the anti-blocking mechanism 7 is located below the filter screen plate 15, and the anti-blocking mechanism 7 includes a top plate 701, a lifting rod 702, a roller 703, a rotating block 704, a return spring 705, a transmission shaft 706 and a motor 707. A lifting rod 702 slides through the inner side of the fixing bracket 16, and one end of the lifting rod 702 close to the filter screen plate 15 is connected to the top plate 701, and a return spring 705 is sleeved on the outer side of the lifting rod 702. The end of the lifting rod 702 away from the top plate 701 is installed with a roller 703 through a movable shaft, and a rotating block is provided below the roller 703. Block 704, one end of the rotating block 704 is connected to a transmission shaft 706, one end of the transmission shaft 706 is connected to a motor 707 through a coupling, and the transmission shaft 706 is connected to the inner wall of the box body 1 through a bearing, and both ends of the filter screen plate 15 are connected to a buffer mechanism 9, the outer side of the buffer mechanism 9 is connected to a side frame 11, and the side frame 11 is connected to the inner wall of the box body 1, the buffer mechanism 9 includes a support spring 901 and a slide rod 902, and a slide rod 902 is installed on the inner side of the side frame 11, and the outer side of the slide rod 902 is sleeved with a support spring 901, and the slide rod 902 is slidably sleeved with both ends of the filter screen plate 15, the shape of the rotating block 704 is triangular, and the buffer mechanism 9 is set to four groups.

[0027] During specific implementation, since there will be a lot of impurities and sediment on the agricultural products, these sediments and impurities need to be discharged after the agricultural products are cleaned and sterilized by the agricultural products cleaning and sterilizing machine. However, some of the sediments and impurities are large in particle size and are easily blocked by being discharged from the pipeline for a long time. Therefore, a filter screen that blocks large particles of sediment or impurities is usually installed in the agricultural products cleaning and sterilizing machine. After a long period of filtration, some sediments and impurities are easily stuck in the filter holes of the filter screen, which will affect the filtration efficiency. When the sediments and impurities are stuck in the filter holes of the filter plate 15, the motor 707 can be started to drive the transmission shaft 706 to rotate, and the transmission shaft 706 then drives the rotating block 704 to rotate.

One end of the push plate 1302 is connected to the push rod 1301, and the push rod 1301 slides through one side of the box body 1.

[0029] During specific implementation, since mud, sand and impurities will accumulate above the filter screen plate 15, which is inconvenient to clean quickly, you can open the box door 4 after draining the water from the drain pipe 8, and then push the push rod 1301, so that the push rod 1301 drives the push plate 1302 to disengage from the groove 1303, and then the push rod 1301 pushes the push plate 1302 to scrape above the filter screen plate 15, which can quickly push the accumulated mud, sand and impurities to a position close to the box door 4, making it convenient for staff to clean quickly and improving the practicality of the agricultural product cleaning and sterilization machine.

[0030] Working principle: When using the agricultural product cleaning and sterilizing machine that can prevent filter clogging, first put the agricultural product from the feed hopper 3 so that the agricultural product falls on the cleaning component 14, and the water inlet pipe 10 puts water into the box body 1. The cleaning component 14 rotates to drive the agricultural product to rotate and move, which is convenient for cleaning. After cleaning is completed, the sewage is discharged through the drain pipe 8. At the same time, the partition 12 and the cleaning component 14 carry the agricultural product, and the filter plate 15 filters the mud and impurities. After filtering is completed, the mud and impurities stuck in the filter holes of the filter plate 15 are knocked loose by the buffer mechanism 9 and the anti-blocking mechanism 7, and then the mud and impurities are pushed to a position near the box door 4 by the pushing mechanism 13. Then the ozone generator 5 disinfects the agricultural product. After disinfection, it is dried by the hot air blower 6. Finally, the box door 4 is opened, the agricultural product is taken out, and the mud and impurities on the filter plate 15 are cleaned, thereby improving the working efficiency and practicality of the agricultural product cleaning and sterilizing machine.
