When working, the switch of the driving motor 11 is first turned on, so that the driving motor 11 drives the rotating rod 12 to rotate, and then the cleaning brushes that need to be cleaned are cleaned. The cleaned and screened corn is poured into the cleaning tank 1, and the water spray component 18 is turned on to spray water on the inside of the cleaning tank 1. The cleaning rod 16 is rotated under the drive of the rotating rod 12, so that the corn piled together is constantly stirred and turned over. The corn is cleaned by the water spray component 18. In the process of cleaning the corn, the surface of the turned corn is constantly wiped by the cleaning brush 17, so that the impurities on the corn are better cleaned, and the corn that meets the specifications will pass through the sieve plate 1 with water stains. 3 falls onto the water filter plate 14, so that the water filter plate 14 intercepts the corn, and the waste water flows to the bottom of the cleaning tank 1 through the water filter plate 14. The corn falling onto the water filter plate 14 will roll along the inclined water filter plate 14 to the discharge port 15, and then be collected. The accumulated corn is continuously turned over by the rotation of the cleaning rod 16, so that the cleaning surface of the corn is larger, the problem of cleaning dead corners caused by corn accumulation is reduced, and the cleaning of the corn is more sufficient. At the same time, by setting the water filter plate 14 in an inclined state, the corn can be better collected after screening.

[0024] like Figures 1 to 5As shown, the water spray assembly 18 includes a water outlet pipe 2; the water outlet pipe 2 is fixedly connected to the top of the cleaning tank 1; a connecting pipe 21 is fixedly connected to the side wall of the water outlet pipe 2; the connecting pipe 21 penetrates the wall of the cleaning tank 1 and extends to the inside of the cleaning tank 1; a plurality of fixing rods 22 are fixedly connected to the top of the inner wall of the cleaning tank 1; an annular pipe 23 is fixedly connected to the end of the fixing rod 22; the end of the connecting pipe 21 is fixedly connected to the annular pipe 23; the connecting pipe 21 connects the water outlet pipe 2 and the annular pipe 23 to each other; a plurality of water outlets 24 are provided in the middle of the annular pipe 23; the water outlets 24 are provided on the surface of the water outlets 24. The sieve plate 13 is arranged so that when it is working and the corn needs to be cleaned, the water pump pre-placed in the water outlet pipe 2 is turned on, so that the water source in the water outlet pipe 2 flows to the inside of the annular pipe 23 through the connecting pipe 21 under the action of the water pump, and then the water source in the annular pipe 23 can be sprayed into the cleaning tank 1 through multiple dispersed water outlets 24. Through the arrangement of the annular pipe 23 and the water outlet 24, the water source sprayed into the cleaning tank 1 can be more sufficient, thereby increasing the cleaning range, making the corn more fully cleaned, and improving the quality of the corn cleaning.

[0025] like Figure 2 and Figure 3 As shown, a scraper 3 is fixedly connected to the end of the cleaning rod 16; the side wall of the scraper 3 is in contact with the inner wall of the cleaning tank 1. During operation, the scraper 3 is arranged on the cleaning rod 16, and the cleaning rod 16 rotates so that the scraper 3 fits against the inner wall of the cleaning tank 1 to scrape off the corn and impurities adhering to the inner wall of the cleaning tank 1, wherein the corn can be better tumbled and cleaned, and the impurities are driven by the water flow to fall into the bottom of the cleaning tank 1, thereby increasing the cleanliness of the inner wall of the cleaning tank 1 and reducing the residual impurities on the inner wall of the cleaning tank 1.

[0026] like Figure 2 and Figure 3 As shown, a cleaning plate 4 is fixedly connected to the middle of the rotating rod 12; the cleaning plate 4 is arranged above the sieve plate 13; the bottom side wall of the cleaning plate 4 is in contact with the top side wall of the sieve plate 13. When working, the cleaning plate 4 continuously cleans the corns attached to the mesh of the sieve plate 13, thereby reducing the problem of clogging of the mesh of the sieve plate 13 caused by corn accumulation, improving the screening effect of the sieve plate 13, and protecting the stability of the sieve plate 13 when working.

[0027] like Figure 2 and Figure 3As shown, the inner wall of the cleaning tank 1 is fixedly connected to a plurality of groups of elastic rods 51; the elastic rods 51 are arranged below the sieve plate 13; a magnet 5 is fixedly connected to the top of the cleaning plate 4; a magnetic ball 52 is fixedly connected to the end of the elastic rod 51; the magnetic ball 52 corresponds to the position of the magnet 5 and is arranged to attract each other. During operation, when the water filter plate 14 rotates under the drive of the rotating rod 12, the magnet 5 located on the water filter plate 14 moves to the corresponding position of the magnetic ball 52, and the magnetic ball 52 is attracted to the sieve plate 13 by the mutual attraction between the magnet 5 and the magnetic ball 52, so that the magnetic ball 52 knocks on the surface of the sieve plate 13, causing the sieve plate 13 to vibrate slightly, so that the corn inside the mesh of the sieve plate 13 can be shaken off better, the possibility of the sieve plate 13 being blocked is reduced, and the safety and stability of the sieve plate 13 are improved.

[0029] During operation, the drive motor 11 is first turned on to drive the rotating rod 12 to rotate, and then the corn to be cleaned and screened is poured into the cleaning tank 1. At this time, the water spray component 18 is turned on to spray water on the inside of the cleaning tank 1. The cleaning rod 16 is rotated under the drive of the rotating rod 12, so that the corns piled together are constantly stirred and turned over. The corns are cleaned by the water spray component 18. In the process of cleaning the corns, the surface of the turned corns is constantly wiped by the cleaning brush 17 to remove impurities on the corns. The corn with better quality will be washed away, and the corn that meets the specifications will fall onto the water filter plate 14 with water stains through the sieve plate 13, so that the water filter plate 14 intercepts the corn, and the waste water flows to the bottom of the cleaning tank 1 through the water filter plate 14. The corn that falls on the water filter plate 14 will roll down the inclined water filter plate 14 to the discharge port 15 and then be collected. When the corn needs to be washed, the water pump pre-placed in the water outlet pipe 2 is turned on, so that the water source in the water outlet pipe 2 flows to the inside of the annular pipe 23 through the connecting pipe 21 under the action of the water pump, so that the water source in the annular pipe 23 can pass through multiple The dispersed water outlets 24 are used to spray water into the cleaning tank 1. The annular pipe 23 and the water outlet 24 are provided to make the water source sprayed into the cleaning tank 1 more sufficient, thereby increasing the cleaning range. The cleaning rod 16 is provided with a scraper 3, and the cleaning rod 16 is rotated so that the scraper 3 is attached to the inner wall of the cleaning tank 1 to scrape off the corn and impurities adhering to the inner wall of the cleaning tank 1, wherein the corn can be better tumbled and cleaned, and the impurities are driven by the water flow to fall into the bottom of the cleaning tank 1. The cleaning plate 4 continuously cleans the corn attached to the mesh of the sieve plate 13, which can reduce the amount of corn. To solve the problem of clogging of the mesh of the sieve plate 13 caused by accumulation, when the water filter plate 14 rotates driven by the rotating rod 12, the magnet 5 located on the water filter plate 14 moves to the corresponding position of the magnetic ball 52, and the mutual attraction between the magnet 5 and the magnetic ball 52 makes the magnetic ball 52 move toward the direction of the sieve plate 13, so that the magnetic ball 52 knocks on the surface of the sieve plate 13, causing the sieve plate 13 to vibrate slightly, which can make the corn inside the mesh of the sieve plate 13 be shaken off better, and the friction between the rotating rod 12 and the sieve plate 13 is reduced by connecting the rotating rod 12 and the sieve plate 13 with a ball shaft 6.
