The opposite sides of the two guide plates 3 are fixedly connected to the bottom of the crushing box 1. A support plate 4 is fixedly installed on the rear side of the crushing box 1. A motor 5 is fixedly installed on the top of the support plate 4. Two rotating shafts 6 are rotatably installed between the front and rear side walls of the inner cavity of the crushing box 1. One end of the left rotating shaft 6 passes through and extends to the outside of the crushing box 1. The rear side of the left rotating shaft 6 is fixedly connected to the output shaft of the motor 5 through a coupling. Crushing rollers 7 are fixedly installed on the outer surfaces of the two rotating shafts 6.

Among them, a feed port is fixedly installed on the top of the crushing box 1, and a top cover is threadedly connected to the top of the feed port, the purpose of which is to prevent the dust generated during the concrete crushing process from being discharged from the feed port. A discharge port is fixedly installed on the bottom of the crushing box 1, which can discharge the crushed material from the discharge port, thereby not affecting the subsequent crushing work.

The two crushing rollers 7 are located in the same horizontal direction, and the outer surfaces of the two crushing rollers 7 are meshed with each other, so that the purpose of crushing the concrete is achieved, and the concrete can be recycled and reused.

Among them, the opposite sides of the two guide plates 3 form an angle with the left and right side walls of the inner cavity of the crushing box 1 respectively, which facilitates the discharge of the crushed materials from the guide plates 3 through the discharge port, thereby facilitating the discharge of the crushed materials.

Among them, a collection box is fixedly installed between the opposite sides of the two front legs 2. The collection box is located below the discharge port. Its purpose is to collect the crushed materials so that the crushed materials will not pollute the environment.

By adopting the above technical solution and setting up a dust removal mechanism, the purpose of reducing dust inside the crushing box 1 is achieved, so that the dust generated during the concrete crushing process can be processed, reducing the harm caused by dust to the staff and providing a healthy environment for the staff's operation.

Embodiment 2: Please refer to Figures 1-2. On the basis of Embodiment 1, the dust removal mechanism includes two suction boxes 801 fixedly installed on the top wall of the crushing box 1, and the rear side walls of the inner cavity of the two suction boxes 801 are fixedly installed with suction fans 802. Dust-proof nets 803 are fixedly installed between the left and right side walls of the inner cavity of the two suction boxes 801. Wind collecting hoods 804 are fixedly installed at the bottom of the two suction boxes 801. A water tank 805 is fixedly installed on the top of the crushing box 1, and a double-outlet water tank 805 is fixedly installed on the top of the water tank 805. Pump 806, the water suction port of the double-outlet water pump 806 is fixedly installed with a water suction pipe 807 with one end penetrating and extending into the water tank 805, and the two water outlets of the double-outlet water pump 806 are respectively fixedly installed with drainage pipes 808, and the left and right sides of the crushing box 1 are fixedly installed with branch pipes 809 with one end penetrating and extending into the inside thereof, and the opposite sides of the two branch pipes 809 are fixedly installed with nozzles 810, and the tops of the two branch pipes 809 are respectively fixedly connected to one end of the two drainage pipes 808 away from the double-outlet water pump 806.

Among them, a water inlet is fixedly installed on the right side of the water tank 805, and its purpose is to send water from the water inlet into the interior of the water tank 805. The bottom of the dual-outlet water pump 806 is connected to the top of the water tank 805 by a fixed block, so that the dual-outlet water pump 806 can work stably, so that the dual-outlet water pump 806 will not shake during use and cause damage to the internal parts.

Among them, a receiving column is fixedly installed on the top of the crushing box 1, and the top of the receiving column is fixedly connected to the outer surface of the left drain pipe 808, which plays a role in supporting the left drain pipe 808, so that the drain pipe 808 can be stably supported during drainage and will not be broken due to gravity.

By adopting the above technical scheme, the dust generated in the concrete crushing process can be sucked to the top of the crushing box 1 by setting the suction box 801, the suction fan 802, the dust-proof net 803 and the wind collecting hood 804. By setting the double-outlet water pump 806, the water tank 805, the suction pipe 807, the drainage pipe 808, the branch pipe 809 and the nozzle 810, the purpose of reducing the sucked dust is achieved, so that the dust and water can be mixed, and the dust will not float to the outside of the crushing box 1 and pollute the environment.

The working principle of the above embodiment is:

When dust needs to be removed, first unscrew the top cover on the feeding port, then feed the concrete block into the crushing box 1, screw the top cover onto the feeding port, and then start the motor 5. The motor 5 drives the left rotating shaft 6 to rotate, and the left rotating shaft 6 drives the left crushing roller 7 to rotate, and the left crushing roller 7 drives the right crushing roller 7 to rotate, so that the concrete block is crushed between the two crushing rollers 7. At the same time, start the two suction fans 802 at the same time, and the two suction fans 802 suck the dust generated during the crushing to the top of the crushing box 1. The dustproof net 803 prevents the dust from being sucked into the interior of the suction box 801. Then Start the dual-outlet water pump 806, which delivers the water in the water tank 805 to the two drainage pipes 808 through the suction pipe 807 at the same time. The two drainage pipes 808 deliver the water to the two branch pipes 809 at the same time. The two branch pipes 809 deliver the water to the crushing box 1 through the nozzles 810 at the same time, thereby mixing the dust sucked up by the suction fan 802 with the water, thereby achieving the purpose of dust reduction, and then the mixed dust is discharged from the discharge port along the guide plate 3 together with the crushed material, and is collected and recycled through the collecting box, thereby completing the dust reduction work of the crushing box 1.
