[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and groundwater resources and the environment. Water conservancy projects are widely constructed due to their scientific and developmental nature. However, if the gravel and sediment generated during the construction process are not treated in a timely manner, they will cause waste to nature. Therefore, various sediment separators have emerged.

When the vibrator 13 is turned on, the second screen plate is driven through the connecting frame 12. The second and third screen plates 28 and 29 vibrate simultaneously to prevent mud and sand from clogging them. A sliding rod 8 is fixedly connected inside the housing 2. Two sets of sliding rods 8 are provided: one set is located above the second screen plate 28, and the other set is located above the third screen plate 29. A movable plate 7 is slidably connected to the outer side of the sliding rod 8, moving along the outer side of the sliding rod 8. A mounting box 14 is fixedly connected to the top of the movable plate 7, moving the mounting box 14 along with it. A fixed plate 17 is fixedly connected inside the mounting box 14, and an electric telescopic rod 15 is fixedly connected to the top of the fixed plate 17. A fixed frame 21 is slidably connected inside the mounting box 14. The fixed frame 21 moves along the inside of the second collection box 4. A scraper 20 is fixedly connected to the bottom of the fixed frame 21 through the bottom of the moving plate 7. The movement of the fixed frame 21 moves the scraper 20. There are two sets of scrapers 20. The bottoms of the two sets of scrapers 20 are respectively in contact with the second screen plate 28 and the third screen plate 29. The movement of the two sets of scrapers 20 cleans the surfaces of the second screen plate 28 and the third screen plate 29. The output end of the electric telescopic rod 15 passes through the bottom of the fixed plate 17 and is fixedly connected to the fixed frame 21. The movement of the electric telescopic rod 15 moves the fixed frame 21. The moving plate 20 has pressure sensors 22 fixedly connected symmetrically on both sides to monitor the pressure between the scraper 20 and the second screen plate 28 and the third screen plate 29, so as to better adjust the position of the scraper 20. The bottom of the moving plate 7 is fixedly connected to the nozzle 19, which sprays water to separate the mud and sand on the surface of the second screen plate 28 and the third screen plate 29 and clean the surface of the second screen plate 28 and the third screen plate 29. The inside of the box 2 is symmetrically rotated and connected to the crushing rollers 11.

[0026] Furthermore, a reciprocating screw 6 is rotatably connected inside the housing 2, and the end of the moving plate 7 away from the slide bar 8 is threadedly connected to the reciprocating screw 6. The rotation of the reciprocating screw 6 moves the moving plate 7.
[0027] Furthermore, a first collection box 3 is fixedly connected to one side of the box body 2. A connection port is provided between the first collection box 3 and the box body 2, so that the sand screened by the third sieve plate 29 can enter the first collection box 3. A second collection box 4 is fixedly connected to one side of the box body 2 and above the first collection box 3. A connection groove is provided between the box body 2 and the second collection box 4, so that the gravel screened by the second sieve plate 28 can enter the second collection box 4.

[0028] Furthermore, a second guide plate 26 is fixedly connected to the side of the box 2 near the second collection box 4. The mud and sand contained in the gravel in the second collection box 4 move along the second guide plate 26 to the surface of the third screen plate 29. A first guide plate 10 is fixedly connected to the bottom of a set of second screen plates 28, so that the mud and sand screened by the second screen plate 28 can fall more easily along the first guide plate 10 between the two sets of crushing rollers 11.
[0029] Furthermore, there are two sets of reciprocating lead screws 6. One end of each set of reciprocating lead screws 6 passes through one side of the housing 2 and is fixedly connected to a pulley 24. There are two sets of pulleys 24, and the two sets of pulleys 24 are connected by a transmission belt 25.

A second connecting pipe 27 is fixedly connected to the end of the hose 16 away from the first connecting pipe 18, passes through one side of the housing 2, and is fixedly connected to one side of the housing 2. Water is introduced into the first connecting pipe 18 through the second connecting pipe 27 and the hose 16, and then sprayed by the nozzle 19.
[0031] Furthermore, a drive motor 23 is fixedly connected to the outside of the housing 2 via a support frame. One end of a set of reciprocating lead screws 6 passes through one side of the support frame and is fixedly connected to the output end of the drive motor 23. After the drive motor 23 is turned on, it rotates the reciprocating lead screws 6.
[0032] Furthermore, a motor gear set 5 is installed on one side of the housing 2. One end of the crushing roller 11 is fixedly connected to the motor gear set 5. The motor gear set 5 includes a motor, a mounting frame, and two sets of gears. One end of each set of crushing rollers 11 is fixedly connected to the two sets of gears via a rotating shaft. One side of the mounting frame is rotatably connected to the two sets of gears, and the other side of the mounting frame is fixedly connected to the motor. The output end of the motor passes through one side of the mounting frame and is fixedly connected to the center of one side of a set of gears. When the motor is turned on, it drives the two sets of crushing rollers 11 to rotate under the action of the two sets of gears, crushing large solids in the mud and sand. A control panel 30 is installed on one side of the housing 2. The control panel 30 receives the signal from the pressure sensor 22 and dynamically adjusts the pressure of the electric telescopic rod 15 to ensure a constant cleaning force.
[0033] In use, first connect water to the second connecting pipe 27, then pour the silt into the inlet at the top of the box 2. Turn on the drive motor 23, vibrator 13, and motor gear set 5. After the vibrator 13 is turned on, it drives the second screen plate 28 and the third screen plate 29 to vibrate simultaneously through the connecting frame 12 to prevent silt from clogging the second screen plate 28 and the third screen plate 29. After the drive motor 23 is turned on, it drives the two sets of reciprocating screws 6 to rotate under the cooperation of the two sets of pulleys 24 and the transmission belt 25. The rotation of the reciprocating screws 6 drives the moving plate 7 to move. The movement of the moving plate 7 drives the scraper 20 to move through the fixed frame 21. The scraper 20 moves to clean the surface of the second screen plate 28 to prevent silt from remaining on the surface of the second screen plate 28. The second screen plate 28 is located at the top inside the box 2 and filters out the gravel in the silt. The filtered gravel enters the second collection box 4. The first screen plate 9 filters out the silt mixed in with the gravel. The filtered silt flows along the second guide plate 26. The sand falls onto the surface of the third screen plate 29. The sand screened by the second screen plate 28 falls along the first guide plate 10 into the space between the two sets of crushing rollers 11. Under the action of the motor gear set 5, the two sets of crushing rollers 11 rotate simultaneously to crush the larger solids in the sand. The crushed sand falls onto the surface of the third screen plate 29. Water enters the first connecting pipe 18 through the second connecting pipe 27 and the hose 16, and is finally sprayed out by the nozzle 19. The nozzle 19 washes the sand on the surfaces of the second screen plate 28 and the third screen plate 29. With the back-and-forth movement of the pressure sensor 22, the surface of the second screen plate 28 and the third screen plate 29 is better prevented from clogging, and the sand is better separated. The pressure sensor 22 monitors the pressure between the scraper 20 and the second screen plate 28 and the third screen plate 29. When the pressure value is too high, the electric telescopic rod 15 opens and moves the scraper 20 through the fixed frame 21 to adjust the position of the scraper 20. The separated sand enters the first collection box 3.
