The advantage is that river sand is added from the feed pipe 7 to the inside of the mounting plate 4 20 and the filter plate 4 19, and the water outlet pipe 9 is set to discharge the water after cleaning. At the same time, the setting of the valve 10 plays the effect of controlling the switch. The valve 10 is a solenoid valve setting, which is a known technology.

[0029] Four support columns 4 are fixedly arranged on the lower end surface of the bottom plate 1 to provide support.

[0030] When in use, the device uses an external control device and power supply, and the fixed box 8 is moved to the right below the mounting plate 12. Since the filter plate 11 is the screening device with the smallest sieve hole, a suitable filter plate 11 can be selected according to needs, and the suitable filter plate 11 is fixed on the fixing plate 2 14 through the locking screws and the fixing block 13, and then the whole is placed in the fixed box 8 through the electric push rod 6, and then river sand is added to the inside of the mounting plate 4 20 and the filter plate 4 19 through the feeding pipe 7, and then the fixed box 8 is filled with sand. Cleaning water or other cleaning agents are added inside. At this time, the valve 10 is in a closed state, and then the forward and reverse motor 26 is started. The forward and reverse motor 26 drives the fixed plate 2 14 to rotate, so that the sand and gravel are cleaned and screened. After the screening is completed, the filter plate 11 and the mounting plate 1 12 are moved out of the fixed box 8 through the electric push rod 6, and then the bottom plate 1 is removed, that is, the fixed box 8 is removed, and the mounting plate 1 12, the mounting plate 2 16, the mounting plate 3 18 and the mounting plate 4 20 are disassembled in turn, so that the screened and cleaned river sand is taken out in turn.
