[0002] Agricultural product processing involves transforming raw agricultural products into consumable or higher-value-added products through a series of processes. This process typically includes cleaning, cutting, cooking, drying, fermentation, and packaging. Agricultural product processing requires the use of screening machines, which are used to sort, grade, and clean various crops. They effectively remove impurities, dust, and damaged or substandard particles from agricultural products, thereby improving their quality and market value.

[0003] However, the existing screening machines have the following disadvantages: after the agricultural products are screened, some impurities or dirt will adhere to the screening net, and the screening net needs to be disassembled and cleaned. However, disassembling the screening net takes time, and most of the water pipes fixedly installed in the screening machine are not convenient for adjusting the flushing angle, resulting in incomplete cleaning of the screening net. Therefore, the existing screening machine needs to be improved. Summary of the Invention

[0026] See also Figures 1-4 、 Figure 6 and Figure 8 The utility model provides a technical solution: a screening machine with a cleaning structure, comprising a machine body 1 and a discharge port 6, an inspection door 2 is installed on the outside of the machine body 1 by bolts, a support frame 3 is fixedly sleeved on the outside of the machine body 1, the discharge port 6 is connected to the bottom end of the machine body 1, an auxiliary mechanism 7 is provided in the inner cavity of the machine body 1, a feed port 4 is opened above the machine body 1, and a guide frame 5 is installed above the machine body 1 near the feed port 4.

[0027] See also Figure 1 and Figure 3-Figure 5 One end of the auxiliary mechanism 7 is connected to the motor 8, and the auxiliary mechanism 7 includes a transmission shaft 701, a cleaning brush 702, a screen 703, a fixed rod 704 and a scraper 705. The transmission shaft 701 is installed in the inner cavity of the body 1 through a bearing, and the outside of the transmission shaft 701 is connected to the cleaning brush 702 and the fixed rod 704. One end of the fixed rod 704 is connected to the scraper 705. A screen 703 is installed on the inner side of the body 1 near the bottom of the cleaning brush 702. One end of the transmission shaft 701 is connected to the motor 8 through a coupling. The cross-sectional shape of the scraper 705 is triangular, and the shape of the screen 703 is set to be conical.

[0028] During specific implementation, since the screening machine only uses water flushing and the cleaning efficiency is not high, the transmission shaft 701 can be driven to rotate by starting the motor 8, and the transmission shaft 701 then drives the cleaning brush 702 and the fixed rod 704 to rotate, so that the cleaning brush 702 cleans the surface of the screen 703. At the same time, the fixed rod 704 drives the scraper 705 to scrape the inner wall of the body 1, which can prevent agricultural products from accumulating on the inner wall of the body 1 near the discharge port 6, thereby improving the practicality of the screening machine.

[0029] See also Figures 1-4 and Figure 6-Figure 8 , a cleaning mechanism 9 is installed on the top of the body 1, one end of the cleaning mechanism 9 is connected to a water inlet pipe 10, a water pump 11 is installed on the inner side of the water inlet pipe 10, and the water inlet pipe 10 is located above the body 1, and an annular pipe 12 is connected to the bottom of the cleaning mechanism 9, and the annular pipe 12 is located on the outside of the transmission shaft 701, the cleaning mechanism 9 includes a rotating seat 901, a connecting rod 902, an electric push rod 903 and a hose 904, a connecting rod 902 is movably connected to the top inner wall of the body 1 through the rotating seat 901, one end of the connecting rod 902 is connected to the annular pipe 12 through a movable shaft, the end of the annular pipe 12 away from the connecting rod 902 is connected to the electric push rod 903 through a movable shaft, the end of the electric push rod 903 away from the annular pipe 12 is connected to the inner wall of the body 1 through a movable shaft, one side of the annular pipe 12 is connected to the water inlet pipe 10 through a hose 904, and a circular through-hole is provided at the bottom of the annular pipe 12.

[0030] During specific implementation, after the agricultural product screening machine screens the agricultural products, some impurities or dirt will adhere to the screening net, and the screening net needs to be disassembled and cleaned. However, disassembling the screening net takes time, and most water pipes fixedly installed in the screening machine are not convenient for adjusting the flushing angle, resulting in incomplete cleaning of the screening net. Water can be introduced into the water inlet pipe 10 through the water pump 11, and then transported into the annular tube 12 through the hose 904, and then sprayed out through the through hole of the annular tube 12. At the same time, the electric push rod 903 is started to extend or shorten one end of the annular tube 12, and the connecting rod 902 at the other end of the annular tube 12 rotates on the rotating seat 901, and the flushing angle of the annular tube 12 is quickly adjusted, which facilitates the rapid cleaning of the screening net, facilitates the subsequent screening of agricultural products, and improves the working efficiency of the screening machine.

[0031] Working principle: When using the screening machine with a cleaning structure, first place the agricultural product seeds or materials on the guide rack 5, and enter the inner cavity of the body 1 through the feed port 4. The seeds or materials are then screened through the screen 703. After the seeds or materials are screened, the screened materials or seeds are discharged through the discharge port 6. When it is necessary to clean the body 1 and the screen 703, the auxiliary mechanism 7 and the cleaning mechanism 9 can be used to fully clean the body 1 and the screen 703, thereby improving the working efficiency and practicality of the screening machine. The contents not described in detail in this description belong to the existing technology known to professional and technical personnel in this field.
