The cleaning plate 26 is connected with a limiting rod 25 which is slidingly fitted with the screening box 1 and penetrates the screening box 1. The rod body of the limiting rod 25 penetrating the screening box 1 is welded with a moving block 24, and the moving block 24 is threadedly connected with the reciprocating screw rod 22.

[0037] The driving member comprises a second motor 21 which is bolted on the screening box 1. The output shaft of the second motor 21 is coaxially fixedly connected with the reciprocating screw rod 22.

[0038] The filtering plate 20 is upwardly curved at the end in the sliding direction of the cleaning plate 26. Two cleaning openings 28 are formed on the box body of the screening box 1, and each of the two cleaning openings 28 corresponds to one of the two ends of the filtering plate 20. Each of the cleaning openings 28 is smoothly connected with the corresponding end of the filtering plate 20, and the end of each of the cleaning openings 28 away from the filtering plate 20 is downwardly inclined.

[0040] The cleaning plate 26 penetrates the limiting rod 25 in the vertical direction and is slidingly fitted with the limiting rod 25, and the spring 27 is fixedly arranged between the cleaning plate 26 and the limiting rod 25. The spring 27 is used for providing a space for the cleaning plate 26 to slide over the curved end of the filtering plate 20 and ensuring that the cleaning plate 26 is always in contact with the filtering plate 20.

[0041] The working principle of the first embodiment is as follows: the first motor 3 and the second motor 21 are started. The output shaft of the first motor 3 drives the transmission shaft 4 to rotate, and the transmission shaft 4 drives the gear 5 to rotate. The gear 5 drives the gear ring 6 to rotate, and the gear ring 6 drives the screening drum 7 to rotate. At the same time, the output shaft of the second motor 21 drives the reciprocating screw rod 22 to rotate, and the reciprocating screw rod 22 drives the moving block 24 to move. The moving block 24 drives the limiting rod 25 to reciprocally slide in the horizontal direction. The limiting rod 25 drives the cleaning plate 26 to reciprocally slide along the upper surface of the filtering plate 20.

[0042] Then the water pump 16 is started, and the water pump 16 pumps the water in the water storage tank 15 out, and the water is sprayed into the high-pressure spray pipe 18 through the water pipe 17. The nozzle of the high-pressure spray pipe 18 sprays high-pressure washing water to the screening drum 7. Then the quartz stone is put into the screening drum 7 through the feeding opening 8, and the quartz stone is rolled under the driving of the belt plate 9 in the screening drum 7. At the same time, the quartz stone is washed by the high-pressure water flow.

[0043] The mud and sand produced during the flushing process flows to the filter plate 20 through the guide plate 19, and the filter plate 20 filters the mud and sand to the upper surface of the filter plate 20. Since the cleaning plate 26 slides along the upper surface of the filter plate 20, the cleaning plate 26 pushes the mud and sand to the cleaning port 28. When the cleaning plate 26 passes the raised end of the filter plate 20, the cleaning plate 26 gradually compresses the spring 27. When the mud and sand reach the cleaning port 28, they slide into the cleaning box 30 through the cleaning port 28.

[0044] The filtered wastewater flows into the water storage tank 15, thereby forming a recycling use of water resources. Of course, the embodiment can also be provided with a water inlet on the screening box 1, so that the water inlet communicates the water storage tank 15 and an external water tank, so as to ensure sufficient water.

[0045] The cleaned quartz stone slides to the guide pipe 12 through the discharge port of the screening drum 7, and finally the quartz stone slides out of the guide pipe 12 and falls into the collection box 29.

[0046] Embodiment two: the utility model provides a kind of quartz stone raw material cleaning and screening device as shown in Figures 5 to 6 The difference between the embodiment and embodiment one is that the driving member includes a first pulley 33, a second pulley 34 and a belt 35. The first pulley 33 is fixedly sleeved on the output shaft, i.e., the rotating shaft 31 of the first motor 3, and the second pulley 34 is coaxially fixedly connected with the reciprocating screw rod 22. The first pulley 33 and the second pulley 34 are drivingly sleeved in the belt 35.

[0047] Two fixed blocks 23 are welded and fixed on the screening box 1, and the reciprocating screw rod 22 is located between and rotationally connected with the two fixed blocks 23.

[0048] The rotating shaft 31 is horizontally arranged and fixedly arranged with a universal joint 32 between the transmission shaft 4. A limiting block is welded and fixed in the screening box 1, and the transmission shaft 4 penetrates through and rotationally connects with the limiting block. The limiting block 4 is close to the meshing position of the gear 5 and the gear ring 6, so as to ensure that the gear 5 and the gear ring 6 do not disengage.

[0049] Working principle of embodiment two: the difference between the working principle of the embodiment and embodiment one is that when the output shaft, i.e., the rotating shaft 31 of the first motor 3 rotates, it drives the transmission shaft 4 to rotate through the universal joint 32, and at the same time drives the first pulley 33 to rotate.

[0050] The first pulley 33 rotates at the same time to drive the second pulley 34 to rotate through the belt 35, and the second pulley 34 drives the reciprocating screw rod 22 to rotate.

[0051] The other working processes are the same as those of embodiment one, and will not be described in detail here.

[0052] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
