When the concrete is crushed, it will splash miscellaneous stones and waste chips, threatening the personal safety of the construction workers.

[0004] The solution is to cover the surface of the feed port with a muffler pad, which is a damping sound insulation board with a restrained damping structure. A radiator is fixedly connected to the top of the motor to dissipate the heat of the machine body in time when it is working. Baffles are fixedly connected around the mixing block to block stones, and a shockproof seat is fixedly connected to the tail of the baffle to reduce the overall vibration, solving the problem of splashing stones and waste when the concrete is crushed.

After the water pump 6 is started, water is absorbed from the outside. This water flow enters the second hollow plate 13 through the second hose 11, and is finally sprayed out from the multiple fine holes 14 to remove the dust generated when the concrete is crushed, so as to avoid the dust being too large to affect the surrounding environment.

[0026] Reference Figure 1-2The lower end of the shell 1 is fixedly connected to a plurality of bottom columns 2, and the lower ends of the plurality of bottom columns 2 are all provided with anti-slip pads.

The reciprocating screw rod 15 is provided with a threaded layer, and the threaded layer part is threadedly connected with a slider 16. The slider 16 is slidably connected to the inner top of the crushing chamber 3. The lower end of the slider 16 is fixedly connected to the first hollow plate 12 and the second hollow plate 13. The second hollow plate 13 is located on the right side of the first hollow plate 12. The lower ends of the first hollow plate 12 and the second hollow plate 13 are both provided with a plurality of fine holes 14. The front side of the rotating shaft 17 is connected to the reciprocating screw rod 15. The front sides both extend to the front side of the shell 1 and are equipped with transmission wheels. The two transmission wheels are connected by a transmission belt 19. A suction fan 7 is installed at the upper end of the shell 1. A filter box 8 is arranged on the front side of the suction fan 7. A plurality of filter screens are arranged in the filter box 8. The suction end of the suction fan 7 extends into the filter box 8. The lower end of the filter box 8 is connected to the interior of the first hollow plate 12 through a first hose 10. A water pump 6 is installed on the right side of the shell 1. The water outlet end of the water pump 6 is connected to the interior of the second hollow plate 13 through a second hose 11.

Since the two crushing tooth rollers 18 are meshed, the two crushing tooth rollers 18 rotate to crush the concrete entering the housing 1;

[0031] The reciprocating screw rod 15 is rotated by the transmission belt 19, so that the slider 16 drives the first hollow plate 12 and the second hollow plate 13 to move back and forth. After the water pump 6 is started, water is sucked from the outside. This water flow enters the second hollow plate 13 through the second hose 11 and is finally sprayed out from the plurality of fine holes 14 to remove the dust generated when the concrete is crushed, so as to avoid the dust being too large to affect the surrounding environment.

[0032] In the above process, after the suction fan 7 is started, the dust generated in the crushing process is sucked into the first hose 10 through multiple fine holes 14, and then sucked into the filter box 8 through the first hose 10, and filtered by multiple filter nets in the filter box 8, leaving the dust on the filter nets, further reducing the influx of dust into the working environment, and to a certain extent, protecting the physical and mental health of the staff.
