Pipe 6, a valve 7 is provided on the water inlet pipe 6, the left end of the water inlet pipe 6 is closed, the water inlet pipe 6 is fixed on the outer side of the rear side of the box body 1, the water outlet pipe is rotatably connected to the water inlet pipe, and a plurality of water holes 8 are provided on the lower part of the peripheral wall of each water outlet pipe 3; the driving member includes a gear 9 and a rack 10, each of the water outlet pipes 3 is sleeved and fixed with a gear 9, both ends of the rack 10 respectively penetrate the left and right side plates of the box body 1, and the upper ends of multiple gears 9 are engaged with the rack 10; the rack 10 is driven by the hydraulic cylinder 12 to move left or right, and the right end of the rack 10 is connected to a pull rope 13, and the other end of the pull rope 13 penetrates the right side plate of the box body 1 and is connected to the right end of the bottom surface of the screen 2.

[0025] The screen 2 includes a rectangular frame 2a and a mesh 2b, wherein the mesh 2b is arranged inside the rectangular frame 2a; the left and right inner surfaces of the box body 1 are provided with arc grooves 14 with protrusions facing each other, and the screen 2 is located between the two arc grooves 14; the left and right outer surfaces of the rectangular frame 2a are arc surfaces corresponding to the arc grooves 14 on the same side, and the front and rear outer surfaces of the rectangular frame 2a respectively slide in contact with the front and rear inner surfaces of the box body 1.

[0026] An arc hole 15 for the pull rope 13 to slide through is provided on the right side plate of the box body 1. The arc hole 15 is located at the lower side of the right arc groove 14, and the arc protrusion faces downward. A drainage pipe 16 is connected to the box body 1 below the arc hole 15.

[0027] The left and right side plates of the box body 1 are both provided with through holes 17 for the rack 10 to slide through, and the rack 10 is in sliding contact with the inner top surface of the box body 1; a horizontal plate 18 is fixed to the upper part of the left outer side of the box body 1, and a hydraulic cylinder 12 with a piston end connected to the left end of the rack 10 is fixed on the horizontal plate 18.

[0028] When the piston end of the hydraulic cylinder 12 moves to the left to the limit state, the spring 4 is in a natural state, the left end of the rectangular frame 2a contacts the lower end of the left arc groove 14, and the right end contacts the upper end of the right arc groove 14, and the multiple water holes 8 on the water outlet pipe 3 are located at the lower right part of the peripheral wall of the water outlet pipe 3 (such as Figure 3 , Figure 4 as shown).

[0029] When the piston end of the hydraulic cylinder 12 moves to the right to the limit state, the spring 4 is in a stretched state, the left end of the rectangular frame 2a contacts the upper end of the left arc groove 14, and the right end contacts the lower end of the right arc groove 14, and the multiple water holes 8 on the water outlet pipe 3 are located at the lower left part of the peripheral wall of the water outlet pipe 3.

[0030] When in use, in the initial state, the valve 7 is closed, the screen 2 is in a state of lower left and higher right, the door body 5 is opened, and the quartz sand to be desludged is placed on the top of the screen 2. Under the action of its own gravity, the quartz sand slides to the left until the height of the quartz sand on the left side of the top surface of the screen 2 is close to the middle of the screen 2, stop feeding, and close the door body 5;

[0031] Open the valve 7, the piston end of the hydraulic cylinder 12 drives the rack 10 to move right or left. In the initial state, water enters the multiple water outlet pipes 3, and the water is sprayed to the lower right through the water holes 8 on the water outlet pipes 3. When the rack 10 moves to the right, it can mesh with the gear 9 to drive the water outlet pipe 3 to rotate clockwise (the clockwise rotation of the water outlet pipe 3 is Figure 3 At the same time, the right end of the rack 10 pulls the pull rope 13, and the end of the pull rope 13 connected to the screen 2 pulls the right end of the screen 2, so that the screen 2 rotates clockwise (the clockwise rotation of the screen 2 is Figure 3The spring 4 is stretched, and during the rightward movement of the rack 10, the screen 2 gradually changes from a state of being low on the left and high on the right to a state of being high on the left and low on the right. When the screen 2 is in a state of being high on the left and low on the right, the quartz sand on the left part of the top surface of the screen 2 moves to the right along the inclination direction of the screen 2 under the action of its own gravity, thereby realizing the rolling of the quartz sand, and the water sprayed from the multiple water outlet pipes 3 can impact the quartz sand rolling to the right clockwise, and a counter-attack can be formed between the quartz sand and the water, which can be conducive to the soil on the quartz sand being washed away, and the rolling quartz sand can be washed by water in all directions, and the mutual friction and contact between the rolling quartz sands is also conducive to the separation of the soil on the quartz sand from the quartz sand; during the process of the hydraulic cylinder 12 driving the rack 10 to move leftward and return to the initial state, the water outlet pipe 3 rotates counterclockwise (the counterclockwise rotation of the water outlet pipe 3 is Figure 3 (viewing angle in the middle), under the restoring force of the spring 4, the screen 2 gradually changes from a state of being high on the left and low on the right to a state of being low on the left and high on the right. Under the action of its own gravity, the quartz sand moves to the left along the tilt direction of the screen 2, thereby realizing the rolling of the quartz sand. Moreover, the water sprayed from the multiple water outlet pipes 3 can impact the quartz sand rolling to the left in a counterclockwise direction. The washed mud enters the lower part of the screen 2 along with the water flow through the mesh 2b and flows out of the box 1 through the drainage pipe 16.

[0032] Therefore, when the hydraulic cylinder drives the rack 10 to reciprocate left and right, the screen 2 swings clockwise or counterclockwise, so that the quartz sand can be more comprehensively washed by water, thereby improving the desludging efficiency and desludging quality;

[0033] After the quartz sand is desludging, the valve 7 is closed to make the screen 2 higher on the left and lower on the right, and the door 5 is opened to facilitate the discharge of the material.
