[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model features a crushing assembly. Construction waste concrete solid waste enters the crushing box through the feeding chute. Turning on the crushing motor drives the first crushing roller to rotate, which in turn drives two main gears to rotate. This meshing action drives two toothed belts to rotate, which in turn drives two first and second auxiliary gears to rotate, thus driving the second crushing roller to rotate. The second crushing roller, working in conjunction with the first crushing roller, crushes the solid waste. The first and second bidirectional sleeves, under the action of the limiting rod, restrict the movement of the first and second crushing rollers, facilitating the crushing and cleaning of construction waste solid waste, making it recyclable. The crushed construction waste falls into a filter plate through the discharge chute, further screening large particles of solid waste. The properly crushed solid waste falls into a collection box for unified collection.

[0018] 2. This utility model is equipped with a dust removal component. When the construction solid waste in the crushing box is crushed, dust is generated. The controller controls the start of the vacuum cleaner and simultaneously opens the solenoid valve to suck the dust in the crushing box into the vacuum cleaner through the suction pipe. This helps to ensure that the dust generated during the crushing of construction solid waste does not accumulate and enter the external environment through the feeding chute, thus preventing any impact.

[0027] A first crushing roller 501 is connected to a second crushing roller 502 on its outer wall. Both ends of the first crushing roller 501 are fixedly fitted with main gears 505. Both ends of the second crushing roller 502 are fixedly fitted with first auxiliary gears 507. The outer walls of both main gears 505 and the first auxiliary gears 507 are fitted with toothed belts 504. The bottom ends of the inner walls of both toothed belts 504 are fitted with second auxiliary gears 508. A limit rod 503 is fixedly fitted to the middle of both second auxiliary gears 508. A crushing motor 506 is fixedly connected to the right side of the crushing box 4, and the drive end of the crushing motor 506 is fixedly connected to the right end of the first crushing roller 501. A limiting mechanism is located at both ends of the outer walls of the first crushing roller 501, the second crushing roller 502, and the limit rod 503, and is used to control the first crushing roller 501 and the second crushing roller 502 under the support of the limit rod 503. The rotational movement limit of 2 includes two first bidirectional sleeve rods 509. The bottom ends of the two first bidirectional sleeve rods 509 are movably sleeved on both ends of the outer wall of the limit rod 503. The top ends of the two first bidirectional sleeve rods 509 are movably sleeved on the outer wall of the first crushing roller 501 near both ends. The outer wall of the limit rod 503 near the two first bidirectional sleeve rods 509 is movably sleeved with a second bidirectional sleeve rod 510. The top ends of the two second bidirectional sleeve rods 510 are movably sleeved on the outer wall of the second crushing roller 502 near both ends. The outer walls of the first crushing roller 501 and the second crushing roller 502 are rotatably connected to the crushing box 4 through bearings. The bottom end of the crushing motor 506 is fixedly connected to a support seat 6. The bottom end of the support seat 6 is fixedly connected to the top end of the worktable 1 near the right side.

Specific Implementation Example 2

[0030] Please see Figure 1 and Figure 4Based on the first specific embodiment, it also includes a dust removal component 2. The dust removal component 2 is located at the top of the workbench 1 near the left side and is used to adsorb the dust generated during crushing in the crushing box 4. The dust removal component 2 includes a vacuum cleaner 201. A controller 203 is fixedly connected to the top of the vacuum cleaner 201. A suction pipe 204 is fixedly connected to the middle of the top of the vacuum cleaner 201.

A solenoid valve 205 is fixedly connected to the outer wall of the suction pipe 204 near one end. A discharge pipe 202 is fixedly connected to the left side of the vacuum cleaner 201 near the bottom.

[0031] Specifically: When crushing construction solid waste in the crushing box 4, dust is generated. The controller 203 controls the vacuum cleaner 201 to be turned on, and at the same time the solenoid valve 205 is opened to suck the dust in the crushing box 4 into the vacuum cleaner 201 through the suction pipe 204.

[0032] The working principle of this utility model is as follows: Solid waste concrete from construction is fed into the crushing box 4 through the feed trough 3. The crushing motor 506 is turned on, driving the first crushing roller 501 to rotate, which in turn drives the two main gears 505 to rotate. Under meshing action, the two toothed belts 504 rotate, which in turn drives the two first auxiliary gears 507 and second auxiliary gears 508 to rotate, thus driving the second crushing roller 502 to rotate. This roller, in conjunction with the first crushing roller 501, crushes the solid waste. The first bidirectional sleeve 509 and the second bidirectional sleeve 510, under the action of the limiting rod 503, control the movement of the first crushing roller 501 and the second crushing roller 502. The device uses a limit switch to crush and clean construction waste solid waste, turning it into recyclable resources. The crushed construction waste falls into the filter plate 7 through the discharge chute 11, where large particles of solid waste are further screened. The crushed solid waste that passes the test falls into the collection box 8 for unified collection. Dust is generated when crushing the construction solid waste in the crushing box 4. The controller 203 controls the vacuum cleaner 201 to be turned on, and at the same time, the solenoid valve 205 is opened to suck the dust in the crushing box 4 into the vacuum cleaner 201 through the suction pipe 204, ensuring that the dust generated when crushing the construction solid waste does not accumulate and enter the external environment through the feed chute 3.
