[0034] Embodiment 2

[0035] If considering the equipment cost, the cleaning mechanism in the filter box 11 can be taken out. In this way, the equipment cost can be reduced, but manual cleaning work on the filter box 11 is required.

[0036] It should be noted that: The specific model of the motor 2 is selected by those skilled in the relevant art, and the above regarding the motor 2 belongs to the prior art, and this solution will not be elaborated.

[0037] The working principle of the present utility model:

[0038] First, externally connect the power supply to the equipment that requires electricity. Then, start the motor 2. The rotation of the output shaft of the motor 2 drives the active rotating column 3 to rotate. The rotation of the active rotating column 3 drives the first driven rotating column 5 and the second driven rotating column 13 to rotate and drives the conveyor belt 6 and the transmission belt 14 to operate. Place the sand and gravel on the conveyor belt 6, and continuously transport the sand and gravel to the filter box 11 through the conveyor belt 6. The rotation of the second driven rotating column 13 drives the elliptical wheel 15 to rotate, so that the filter box 11 is continuously lifted and dropped in the U-shaped housing 9 and reciprocates. Since the elliptical wheel 15 is located below one side of the filter box 11, the amplitude of the up and down movement of the filter box 11 on one side of the elliptical wheel 15 is greater than that on the other side, so that small-particle sand and gravel will be screened out through the filter holes and concentrated through the fine sand collection hopper 8. Place a container below the fine sand collection hopper 8 to collect the small-particle sand and gravel. The large-particle sand and gravel will gather towards the baffle 10 due to continuous up and down vibration. Start the motor 18. The rotation of the output shaft of the motor 18 drives the ball screw 19 to rotate, thereby driving the ball nut 20 and the mounting block 21 to move, and then driving the cleaning brush 24 to start working. The cleaning brush 24 will sweep the sand and gravel at the bottom upwards. During the continuous upward sweeping process, the hydraulic rod 23 will be continuously retracted under force. The sand and gravel swept upwards by the cleaning brush 24 are filtered again through the filter box 11, and at the same time, the sand and gravel stuck in the filter holes are swept out, making the filtering accuracy higher. Then, open the baffle 10, and the filtered large-particle sand and gravel will be concentrated through the sand and gravel discharge hopper 17. Place a collection container or a transportation device below the sand and gravel discharge hopper 17 to collect or centrally transport the large-particle sand and gravel.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
