A screening plate is slidably connected to one side of the inner wall of the sorting box, a force-bearing plate is fixedly installed on the top of the screening plate, a reset spring is fixedly installed on one side of the screening plate, and the other end of the reset spring is fixedly connected to the sorting box, and a rotating shaft that penetrates and extends into the sorting box is rotatably connected to one side of the sorting box. The utility model provides a novel sand and gravel sorting machine, and at the same time, the rotating rod rotates and drives the rotating shaft to rotate through the pulley group, and the force-bearing plate can be squeezed by the extrusion plate, so that the screening plate is moved and the reset spring is squeezed.

[0043] In this embodiment, the mobile component includes:

[0044] A crossbar 10, which is fixedly mounted on the outer wall of the sorting box 1 near the upper position of the moving block 6, a moving groove 11 and a transmission chamber 12 are provided on the lower surface of the crossbar 10, a motor 13 is rotatably mounted in the moving groove 11, a threaded block 16 that slides with the moving groove 11 is threadedly connected to the motor 13, and the lower surface of the threaded block 16 is fixedly connected to the moving block 6, one end of the motor 13 passes through the side wall of the moving groove 11 and extends into the transmission chamber 12, a bevel gear 15 coaxially connected to the motor 13 is provided in the transmission chamber 12, and a bevel gear 14 is meshedly connected to the circumferential side of the bevel gear 15, a motor 13 is mounted on the lower surface of the crossbar 10 near the transmission chamber 12, and the output shaft of the motor 13 passes through the outer wall of the crossbar 10 and extends into the transmission chamber 12 and is coaxially connected to the bevel gear 14;

[0045] In this embodiment, the spray assembly includes:

[0046] There are two grooves 24, which are symmetrically arranged and both are opened on the inner cavity wall of the upper part of the sorting box 1. A water collecting tank 23 is opened in the sorting box 1 and near the two grooves 24. A plurality of linearly equidistantly distributed mist nozzles 25 are installed in the grooves 24, and the input end of the mist nozzle 25 passes through the side wall of the groove 24 and extends into the water collecting tank 23. A water tank 27 is fixed on the peripheral side of the sorting box 1 and near the water collecting tank 23. A booster water pump 28 is installed in the water tank 27, and the output end of the booster water pump 28 passes through the water tank 27 and the side wall of the sorting box 1 and extends into the water collecting tank 23.

[0047] Among them, the working principle of this device is as follows:

[0048] First, start the motor three 22 and the motor one 7 as well as the moving component and the spray component;

[0049] When the motor 3 22 is working, the output shaft of the motor 3 22 rotates and drives the eccentric block 20 to rotate. During the rotation of the eccentric block 20, when the protruding end of the eccentric block 20 rotates to the side of the round block 18, the protrusion pushes the round block 18 to move inward and squeezes the spring 19. When the round block 18 moves inward, the screening frame 3 is pushed by the push rod 17 to move toward the side away from the eccentric block 20. When the protrusion of the eccentric block 20 is away from the side of the round block 18, the round block 18 moves outward under the elastic action of the spring 19, and then synchronously pulls the screening frame 3 to move toward the side close to the eccentric block 20. Under the action of the eccentric block 20, the screening frame 3 performs reciprocating translational motion in the inner cavity of the sorting box 1;

[0050] When the motor 7 is working, the output shaft of the motor 7 rotates and drives the dispersion roller 5 to rotate synchronously through the connecting shaft 8, and the multiple paddles on the dispersion roller 5 rotate continuously above the screening frame 3;

[0051] When the moving assembly is working, the motor 2 13 is started, the output shaft of the motor 2 13 rotates and drives the bevel gear 1 14 to rotate, the bevel gear 1 14 drives the bevel gear 2 15 to rotate, and the bevel gear 2 15 drives the motor 2 13 to rotate. Under the action of the thread force, the thread block 16 can be laterally displaced along the moving groove 11. When the thread block 16 is displaced, the moving block 6, the motor 1 7, the connecting shaft 8 and the dispersion roller 5 located below the thread block 16 will also be synchronously displaced with the thread block 16, thereby changing the lateral position of the dispersion roller 5 above the screening frame 3, so as to facilitate the dispersion of sand and gravel accumulated at different positions on the upper surface of the screening frame 3;

[0052] When the spray assembly is working, the booster water pump 28 is started, the booster water pump 28 works, and the water in the water tank 27 is transported to the water collecting tank 23. After receiving the water source, the multiple mist nozzles 25 located in the two grooves 24 begin to spray uniform mist water droplets, and perform dust reduction treatment on the sand and gravel that are about to fall into the inner cavity of the sorting box 1;

[0053] When loading, the operator pours sand and gravel raw materials into the inner cavity of the sorting box 1 through the feeding hopper 4 above the sorting box 1. The dust generated when the sand and gravel raw materials fall and are sorted on the screening frame 3 combines with the mist water droplets formed by multiple mist nozzles 25 and falls, and is finally discharged to the outside from the discharge port at the bottom of the sorting box 1. Under the action of the motor 7 and the moving component, the dispersion roller 5 rotates while continuously reciprocating and lateral displacement on the upper surface of the screening frame 3, so that the sand and gravel raw materials accumulated in various places on the upper surface of the dispersion roller 5 can be flattened and dispersed, thereby greatly improving the sand and gravel sorting efficiency of the device.

[0054] By setting up a moving component and a motor 7, the dispersion roller 5 can rotate while continuously performing a reciprocating lateral displacement on the upper surface of the screening frame 3, so that the sand and gravel raw materials accumulated at various places on the upper surface of the dispersion roller 5 can be spread and dispersed, thereby greatly improving the sand and gravel sorting efficiency of the device, and changing the inefficiency of the traditional sorting device that the sand and gravel raw materials are easily accumulated at one place on the screening frame 3 when feeding and can only rely on the swing of the screening frame 3 itself to slowly disperse; by setting up a spray component, a booster water pump 28 is used for pressurized water delivery, and a uniform mist water quality is sprayed toward the inner cavity of the sorting box 1 through a plurality of mist nozzles 25, so that the dust generated when the sand and gravel raw materials fall and when they are sorted on the screening frame 3 is combined with the mist water droplets formed by the plurality of mist nozzles 25 and falls, which greatly reduces the impact of the dust generated when the sand and gravel are sorted on the surrounding environment of the device, protects the environment and improves the cleanliness of the working environment.
