[0023] In the utility model, when in use, the staff will place the cleaned coal inside the cleaning frame 2 in advance, and then place the cleaning frame 2 inside the processing box 1, and limit it. When cleaning, by starting the water pump 14, the water suction pipe at the bottom of the water pump 14 extends into the bottom inner wall of the water tank 12 without touching it, so that the cleaning water poured into the water tank 12 in advance is transported to the water spray pipe 4 through the water delivery pipe 15, and then sprayed out through the nozzle 5 on the surface of the water spray pipe 4 to clean the coal placed in the cleaning frame 2, so as to remove the dirt on the surface of the coal. In the cleaning process, the reciprocating component 6 provided on the processing box 1 is used to conveniently drive the water spray pipe 4 in the processing box 1 to reciprocate left and right in a straight line, so as to clean the coal placed in the cleaning frame 2. The cleaning effect of the device is more uniform and effectively improved, so that each area of ​​the coal in the cleaning frame 2 can be cleaned. At the same time, the knocking component 8 arranged on the processing box 1 is used to make the 805 arranged on the knocking component 8 reciprocate and knock on one side of the cleaning frame 2, so that the cleaning frame 2 shakes. When the cleaning frame 2 is shaking, the coal placed in the cleaning frame 2 rolls inside the cleaning frame 2, so that the coal buried deep inside the cleaning frame 2 is cleaned by the nozzle 5, and the cleaning effect of the device is further improved. During the long-term use of the device, the screening holes 3 opened on the surface of the cleaning frame 2 are easily blocked by the soil dropped after cleaning. The vibration of the cleaning frame 2 can effectively prevent blockage, improve the screening effect of the device, and separate the cleaned soil from the coal for easy removal.
