[0001] The invention belongs to the technical field of construction waste crushing, and more specifically, particularly relates to a construction waste crushing device with a dust removal function. Background Art

[0002] Construction waste is inevitably generated during the construction production process. The random stacking of these wastes affects the environment and poses a safety hazard. It also pollutes water resources, affects air quality, and produces dust pollution. Therefore, in order to facilitate subsequent unified treatment after the construction waste is generated, it is necessary to break the larger construction waste into small pieces for use.

[0003] When the existing construction waste crushing device is crushing the waste, it often uses water mist to suppress the dust generated in the production process of construction waste by spraying water mist around the crushing machine.

[0035] refer to Figure 1-Figure 8A slot is provided inside the transfer box 18, and an electric push rod B20 is installed on the bottom end surface of the mounting frame 19, and a filter plate 21 is also installed at the bottom end of the electric push rod B20, and the filter plate 21 is inserted into the transfer box 18, and a pump body 22 is also installed on the outside of the dust removal pipe 17, and the pump body 22 is used for exhausting air, and a bottom plate 23 is also plugged into the inside of the crushing box 15, and the bottom plate 23 is used to close the crushing box 15, and a fan B24 is installed at the front end of the crushing box 15, and an air slot 25 is provided on the top surface of the crushing box 15, and the fan B24 installed at the front end of the crushing box 15 exhausts air through the air slot 25 provided at the top end of the crushing box 15, and a through slot is provided on the left side of the crushing box 15, and a baffle 26 is plugged into the through slot provided in the crushing box 15.

[0036] When in use: first, when it is necessary to crush the garbage produced in the construction production process, the baffle 26 installed on the outside of the crushing box 15 can be opened manually, so that the side of the crushing box 15 with the through slot is facing the outside, and the construction garbage to be crushed is placed on the conveyor belt 7 installed in the bracket 6 at the same time, and the side of the crushing box 15 with the air slot 25 is set to face the upper position;

[0037] When construction waste is put onto the conveyor belt 7, the two hydraulic push rods A5 installed at the top of the moving seat 4 can be started to push the bracket 6 together with the conveyor belt 7 upward until the conveyor belt 7 installed in the bracket 6 matches the through slot opened in the crushing box 15. In addition, when the conveyor belt 7 is used to transport the construction waste to the inside of the crushing box 15, the hydraulic push rod A5 can be used to lift the bracket 6 together with the conveyor belt 7 so that the conveyor belt 7 can be kept away from the ground personnel, effectively avoiding the problem of safety hazards caused by the operator accidentally touching the conveyor belt 7 during the process of transporting construction waste.

[0038] When the conveyor belt 7 is driven by the motor B8 installed at the front end of the bracket 6 to put the construction waste into the crushing box 15 installed inside the two frames 11, the baffle 26 installed in the crushing box 15 can be pulled up to close the crushing box 15, and the baffle 26 can be adsorbed to the crushing box 15 by magnetism to quickly seal the crushing box 15;

[0043] Then, the hydraulic push rod B27 installed in the crushing box 15 is started to push the support frame 29 together with the crushing roller 33 installed therein toward one side of the construction waste for crushing. In the crushing process, the two electromagnetic blocks 28 installed on the outside of the crushing box 15 can be energized, and the electromagnetic blocks 28 are energized to generate magnetism so that the two side plates 30 installed in the support frame 29 are repelled and moved inward at the same time. The two side plates 30 move inward to automatically gather the construction waste in the crushing box 15, so that the crushing roller 33 can more fully crush the construction waste, thereby achieving a more practical purpose.

[0044] When unloading is required after crushing is completed, the bottom plate 23 installed in the crushing box 15 can be manually removed, so that the construction waste in the crushing box 15 will fall downward to the inner position of the through groove opened on the top surface of the base 1 under the action of gravity, and then the electric push rod A9 installed in the base 1 is started to use the push plate 10 to quickly push the construction waste put into the base 1 to the outside of the base 1 for subsequent processing, thereby achieving a more practical purpose.
