Construction waste crushing device for construction

Abstract

The invention belongs to the technical field of construction waste crushing, and particularly relates to a construction waste crushing device for construction, which comprises a base, a box body is fixedly connected to the upper surface of the base, a first motor is fixedly connected to the interior of the box body, a first threaded rod is fixedly connected to the surface of an output shaft of thefirst motor, a rotating shaft is fixedly connected to the surface of the first threaded rod, and a first bearing is fixedly connected to the interior of the box body. By arranging a crushing roller,a filter screen and a conveying paddle, when the device is used, people control a second motor and a third motor to rotate through a control switch, the third motor rotates to drive the crushing roller to rotate, then waste is crushed, and the crushed waste falls into a drawer after being filtered through the filter screen; and the rest waste is conveyed into a first machine box and conveyed intoa feeding hopper through the conveying paddle to be crushed again, and the crushing efficiency of the device is improved under the action of the crushing roller, the filter screen and the conveying paddle.

Description

technical field [0001] The invention belongs to the technical field of crushing construction waste, and in particular relates to a construction waste crushing device for construction. Background technique [0002] In the process of bridge building construction, a large amount of construction waste will be produced, and these construction wastes will occupy a large amount of land when they are placed. Secondly, the construction glue, paint, and paint in the construction waste are not only high molecular polymers that are difficult to biodegrade The materials also contain harmful heavy metal elements. These wastes are buried underground, which will cause groundwater pollution and directly endanger the lives of surrounding residents. In order to properly dispose of these construction wastes, research has found that the crushed construction waste can be made Coarse and fine aggregates are used for repeated reuse.

[0002] In the process of bridge building construction, a large amount of construction waste will be produced, and these construction wastes will occupy a large amount of land when they are placed. Secondly, the construction glue, paint, and paint in the construction waste are not only high molecular polymers that are difficult to biodegrade The materials also contain harmful heavy metal elements. These wastes are buried underground, which will cause groundwater pollution and directly endanger the lives of surrounding residents. In order to properly dispose of these construction wastes, research has found that the crushed construction waste can be made Coarse and fine aggregates are used for repeated reuse. In the process of crushing construction waste in the existing rapid construction waste crushing device for building bridges, since the main components of construction waste are masonry and concrete, there will be generated during the crushing process. A large amount of dust, so that when the material is discharged, there will be a serious dust phenomenon at the discharge port of the crushing device, which will pollute the surrounding air environment, and sometimes the equipment is not completely crushed
