[0030] First, start the rotating component 2. The rotating component 2 drives the sand screening component 4 to rotate. Start the drive component 3 and the conveying component 5 to work. The drive component 3 drives the sand screening component 4 to rotate and pours the sand into the sand screening component 4.

[0031] This utility model connects the rotating component 2 and the sand screening component 4. The sand screening component 4 is installed on the rotating component 2. The rotating component 2 can drive the sand screening component 4 to rotate, so that the sand screening component 4 is horizontal, thereby reducing the overall height of the equipment and facilitating transportation. When in use, the rotating component 2 pushes the sand screening component 4 to rotate, which can make the sand screening component 4 present different angles, making it more flexible to use.

[0032] In one embodiment, the rotating assembly 2 includes a fixed shaft 201, which is fixedly connected to the bracket 1. A first rotating seat 202 is rotatably connected to the outer surface of the fixed shaft 201. A first electric push rod 203 is fixedly connected to the top of the first rotating seat 202. A second rotating seat 204 is fixedly connected to the movable end of the first electric push rod 203. A rotating frame 205 is hinged to the outer surface of the second rotating seat 204. The rotating frame 205 is rotatably connected to the bracket 1.

[0033] When the first electric push rod 203 is activated, the movable end of the first electric push rod 203 pushes the second rotating seat 204 to move, and the second rotating seat 204 pushes the rotating frame 205 to rotate. The first rotating seat 202 at the fixed end of the first electric push rod 203 can rotate around the fixed shaft 201.

[0034] In one embodiment, the drive assembly 3 includes a fixed frame 301, which is fixedly connected to a rotating frame 205. A first motor 302 is fixedly mounted on the top of the fixed frame 301.

The rotating shaft 306 is rotatably connected to the rotating frame 205.

[0035] When the first motor 302 is started, the output shaft of the first motor 302 drives the first pulley 303 to rotate. The first pulley 303 drives the second pulley 305 to rotate synchronously through the belt 304. The second pulley 305 drives the rotating shaft 306 to rotate. The fixed frame 301 at the bottom of the first motor 302 provides support for it. The fixed frame 301 and the first motor 302 can rotate with the rotating frame 205.

[0036] In one embodiment, the sand screening assembly 4 includes a screen cylinder 401, which is fixedly connected to a rotating shaft 306. A feed plate 402 and a discharge plate 403 are respectively provided at both ends of the screen cylinder 401. The discharge plate 403 is fixedly connected to a rotating frame 205. A baffle 404 and a feed hopper 405 are fixedly connected to the outer surface of the rotating frame 205. The feed hopper 405 is fixedly connected to the feed plate 402. The rotating shaft 306 is rotatably connected to the feed hopper 405.

[0037] Sand is poured into the feed hopper 405 and enters the screen cylinder 401 along the feed plate 402 on the feed hopper 405. The rotating shaft 306 drives the screen cylinder 401 to rotate. During the rotation, qualified sand passes through the screen cylinder 401 and falls to the bottom. During the falling process, the baffles 404 on both sides of the screen cylinder 401 can prevent the sand from being thrown out to other positions. Unqualified sand is discharged along the discharge plate 403 on the screen cylinder 401.

[0038] In one embodiment, the conveying assembly 5 includes a side plate 501, a conveyor belt 502 is provided on the outer surface of the side plate 501, the side plate 501 is fixedly connected to the rotating frame 205, a second motor 503 is fixedly installed on the outer surface of the side plate 501, and the output shaft of the second motor 503 is connected to the roller shaft of the conveyor belt 502.

[0039] Start the second motor 503. The output shaft of the second motor 503 drives the conveyor belt 502 to rotate within the side plate 501. Qualified sand falls from the screen cylinder 401 onto the conveyor belt 502. The rotation of the conveyor belt 502 can transport it to the rear of the equipment.

[0040] In one embodiment, for the bracket 1, a wheel frame 6 is fixedly connected to the bottom of the bracket 1, and a pulley 7 is rotatably connected to the outer surface of the wheel frame 6.

[0041] There are multiple sets of wheel frames 6, and each set of wheel frames 6 has several rotating pulleys 7. The push support 1 can be moved through the pulleys 7, which facilitates the transportation of the equipment.

[0042] In one embodiment, for the bracket 1, a second electric push rod 8 is fixedly installed at the bottom of the bracket 1, and a circular plate 9 is fixedly connected to the movable end of the second electric push rod 8.

[0043] There are multiple sets of second electric push rods 8. The movable ends of the multiple sets of second electric push rods 8 are fixedly connected to circular plates 9. When the second electric push rod 8 is activated, the movable ends of the second electric push rod 8 push the circular plates 9 down, so that the circular plates 9 contact the ground, which can keep the support 1 stable and prevent the support 1 from moving unnecessarily.

[0044] In summary, the working principle of this utility model is as follows: The pusher bracket 1 can be moved to the desired position via the pulley 7. The first electric push rod 203 on the side of the bracket 1 is activated. The movable end of the first electric push rod 203 pushes the second rotating seat 204 to move. The second rotating seat 204 pushes the rotating frame 205 to rotate. The first rotating seat 202 at the fixed end of the first electric push rod 203 can rotate around the fixed shaft 201. The rotating frame 205 drives the screen cylinder 401 to rotate, thereby adjusting the angle of the screen cylinder 401. The first motor 302 is activated. The output shaft of the first motor 302 drives the first pulley 303 to rotate. The first pulley 303 drives the second pulley 305 to rotate synchronously via the belt 304. 305 drives the rotating shaft 306 to rotate, pouring sand into the feed hopper 405. The sand enters the screen cylinder 401 along the feed plate 402 on the feed hopper 405. The rotating shaft 306 drives the screen cylinder 401 to rotate. During the rotation, qualified sand passes through the screen cylinder 401 and falls below. During the falling process, the baffles 404 on both sides of the screen cylinder 401 can prevent the sand from being thrown out to other positions. Unqualified sand is discharged along the discharge plate 403 on the screen cylinder 401. The second motor 503 is started. The output shaft of the second motor 503 drives the conveyor belt 502 to rotate in the side plate 501. Qualified sand falls from the screen cylinder 401 onto the conveyor belt 502. Through the rotation of the conveyor belt 502, it can be transported to the rear of the equipment.

[0045] Through the above technical solution, 1. By connecting the rotating component 2 and the sand screening component 4, the sand screening component 4 is installed on the rotating component 2. The rotating component 2 can drive the sand screening component 4 to rotate, making the sand screening component 4 horizontal, thereby reducing the overall height of the equipment and facilitating transportation. During use, the rotating component 2 pushes the sand screening component 4 to rotate, which can make the sand screening component 4 present different angles, making it more flexible to use; 2. By connecting the first pulley 303 and the second pulley 305, the diameter of the first pulley 303 is smaller than that of the second pulley 305. When the first pulley 303 drives the second pulley 305 to rotate, the rotation speed of the second pulley 305 and the rotating shaft 306 is lower than that of the first pulley 303. The screen cylinder 401 rotates at the same speed as the rotating shaft 306, and baffles 404 are provided on both sides of the screen cylinder 401 to prevent the sand from being thrown out from above due to the excessive rotation speed of the screen cylinder 401.
