Description

Technical Field

[0001] The invention relates to the technical field of construction waste treatment, and in particular to an environmentally friendly construction waste crushing device. Background Art

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, a large amount of construction waste is generated during the demolition, reconstruction and decoration of buildings. If these wastes are not handled properly, they will have a serious impact on the environment, such as pollution of air, soil and water sources, and even pose a threat to human health. Therefore, how to effectively deal with these construction wastes has become an urgent problem to be solved. Traditional methods often use landfill or simple stacking methods, which not only wastes a lot of recyclable resources, but also causes long-term pollution to the environment.

[0003] Chinese patent (CN 210280152 U) discloses a construction waste crushing device, which is arranged on the ground, connected to a motor arranged on one side of the box base, connected to a transmission gear arranged on the other side of the box base, and a baffle arranged inside the box base; characterized in that: a pair of first front through holes, first rear through holes, second front through holes, and second rear through holes are arranged on the box base above the baffle, and a transmission shaft is arranged between the first front through hole and the first rear through hole, and between the second front through hole and the second rear through hole, and a transmission shaft keyway is arranged on the transmission shaft, one end of one of the transmission shafts is in transmission connection with the motor, and the other end of the transmission shaft is in transmission connection with another transmission shaft through the transmission gear, and the outside of each transmission shaft is respectively sleeved with a first roller and a second roller, and the first roller and the second roller are circumferentially fixed with their respective transmission shafts.

[0004] Although the above patent can quickly replace the spherical rolling head with a new one after the rolling head is damaged, thus saving maintenance time and reducing crushing costs, it is unable to crush larger construction waste, resulting in the phenomenon that it is not suitable for crushing construction waste of various sizes. At the same time, the large amount of dust generated during crushing and rolling cannot be centrally processed, which will not only cause harm to the workers' health, but also pollute the air.

[0005] Therefore, the present invention provides an environmentally friendly construction waste crushing device to solve the above problems. Summary of the invention
