[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1

[0024] See also Figure 1-Figure 4 A raw material crushing device for gravel production includes a crushing box 100, a liquid pump 200 is installed on the side of the crushing box 100, a fixed pipe 300 is installed on the side of the liquid pump 200, and a double-axis motor 400 is installed on the side of the crushing box 100. The side of the double-axis motor 400 is transmission-connected to a crushing roller 500. When the double-axis motor 400 and the liquid pump 200 are started, the double-axis motor 400 immediately drives the crushing roller 500 transmission-connected thereto to rotate clockwise, cooperating with the crushing roller 500 on the other side rotating counterclockwise to perform the corresponding crushing operation, and the liquid pump 200 introduces dust removal liquid into the fixed pipe 300;

[0025] A dust removal assembly 600 is provided inside the crushing box 100. The dust removal assembly 600 includes a fixed rod 601, and a power rod 602 is connected to the side of the dual-axis motor 400. After the dual-axis motor 400 is started, it can synchronously drive the power rod 602, which is connected to it, to rotate clockwise. A bevel gear 1 603 is fixedly connected to the side of the power rod 602. When the power rod 602 rotates clockwise, it can drive the bevel gear 1 603, which is fixed to it, to rotate. The side of the fixed rod 601 is rotatably connected to a transmission rod 604, and the side of the transmission rod 604 is fixedly connected to a bevel gear 2 605. Bevel gear 2 605 is located on the side of bevel gear 1 603, and bevel gear 2 605 is in a meshing state with bevel gear 1 603. When bevel gear 1 603 rotates, bevel gear 1 603 drives bevel gear 2 605, which is meshed with it, to rotate, so that bevel gear 2 605 drives the transmission rod 604, which is fixed to it, to rotate. A forward conveyor belt 606 is mounted on the outside of the transmission rod 604. A spray head 607 is rotatably connected to the side of the fixed pipe 300. The forward conveyor belt 606 is positioned on one end away from the transmission rod 604 and outside of the spray head 607. When the transmission rod 604 rotates, the forward conveyor belt 606 mounted on the outside of the transmission rod 604 rotates, thereby driving the spray head 607, which is connected to the transmission rod 604 via the forward conveyor belt 606, to rotate. This allows the dust removal liquid in the fixed pipe 300 to be sprayed to various locations within the crushing box 100, improving the dust removal efficiency of the device and making it easier to use.

[0026] When in use, the dual-axis motor 400 and the liquid pump 200 are started, and the dual-axis motor 400 immediately drives the crushing roller 500 connected to it to rotate clockwise, and cooperates with the crushing roller 500 on the other side that rotates counterclockwise to perform the corresponding crushing operation, and the liquid pump 200 introduces dust removal liquid into the fixed pipe 300. At this time, the dual-axis motor 400 synchronously drives the power rod 602 connected to it to rotate clockwise, so that the power rod 602 drives the bevel gear 1 603 fixedly connected to it to rotate, and the bevel gear 1 603 drives the bevel gear 2 605 meshing with it to rotate, so that the bevel gear 2 605 drives the transmission rod 604 fixedly connected to it to rotate, and cooperates with the forward conveyor belt 606 assembled on the outside of the transmission rod 604, thereby driving the spray head 607 connected to the transmission rod 604 through the forward conveyor belt 606 to rotate, so that the dust removal liquid in the fixed pipe 300 can be rotated and sprayed to various positions in the crushing box 100.

[0027] Example 2

[0028] See also Figure 1-Figure 4 Based on the first embodiment, an auxiliary assembly 700 is provided at the bottom of the crushing box 100. The auxiliary assembly 700 includes a rotating rod 701. A reverse conveyor belt 702 is mounted on the outer side of the rotating rod 701. The reverse conveyor belt 702 is located outside the power rod 602, away from the rotating rod 701. When the power rod 602 rotates clockwise, the reverse conveyor belt 702 mounted on its outer side causes the rotating rod 701, which is connected to the power rod 602 via the reverse conveyor belt 702, to rotate counterclockwise. A cam 703 is fixedly connected to the outer side of the rotating rod 701. Counterclockwise rotation of the rotating rod 701 drives the cam 703 to rotate counterclockwise. A torsion spring rod 704 is rotatably connected to the bottom of the crushing box 100. One end of the torsion spring rod 704 is fixedly connected to a load-bearing plate 705. The cam 703 is located at the bottom of the load-bearing plate 705. The other end of the torsion spring rod 704 is fixedly connected to a cover plate 706. When the cam 703 rotates counterclockwise, the cam 703 immediately squeezes the force-bearing plate 705 from the bottom of the force-bearing plate 705. Because the force-bearing plate 705 is fixedly connected to the torsion spring rod 704, and the torsion spring rod 704 is rotationally connected to the crushing box 100, the torsion spring rod 704 rotates clockwise and drives the cover plate 706 fixedly connected to the torsion spring rod 704 to rotate, opening the crushing box 100. When the cam 703 continues to rotate and moves away from the force-bearing plate 705, the cover plate 706 is reset under the action of the torsion spring rod 704, closing the crushing box 100, so that the crushing box 100 is in an open and closed state in sequence, preventing dust inside the device from escaping, and further improving the dust removal effect of the device.

[0029] When in use, based on Example 1, when the power rod 602 rotates clockwise, it cooperates with the reverse conveyor belt 702 assembled on its outside, so that the rotating rod 701 connected to the power rod 602 through the reverse conveyor belt 702 rotates counterclockwise, and the rotating rod 701 drives the cam 703 fixedly connected thereto to rotate counterclockwise, and the cam 703 immediately squeezes the force plate 705 from the bottom of the force plate 705. Because the force plate 705 is fixedly connected to the torsion spring rod 704, and the torsion spring rod 704 is rotationally connected to the crushing box 100, the torsion spring rod 704 rotates clockwise and drives the cover plate 706 fixedly connected to the torsion spring rod 704 to rotate, opening the crushing box 100. When the cam 703 continues to rotate and moves away from the force plate 705, the cover plate 706 is reset under the action of the torsion spring rod 704, closing the crushing box 100, so that the crushing box 100 is in an open and closed state in sequence.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
