A crushing device for building materials

Abstract

The invention discloses a grinding device for building materials. The grinding device comprises a machine case, and an inner cavity of the machine case is divided into a grinding cavity and a discharging cavity. A feeding hopper is installed at the top end of the machine case, and the feeding hopper communicates with the grinding cavity. A grinding mechanism is installed at the intermediate position of the grinding cavity, and the grinding mechanism includes grinding rollers. The grinding rollers are transversely mounted at the intermediate position of the grinding cavity through roll shafts,and grinding motors are mounted on the side wall of the grinding cavity. Motor shafts of the grinding motors are connected with the roll shafts by couplings, and connecting frames are installed on theside walls of the grinding rollers. The connecting frames are provided with guide plates, and compensation mechanisms are mounted on the left and right side walls of the grinding cavity. The grindingmechanism is located in the middle of the compensation mechanisms. According to the grinding device for the building materials, included angles between the material blocking plates are adjusted by the screw drive and a connecting rod mechanism, so that the space between the left and right compensation mechanisms can be enlarged or reduced, and more suitable grinding operations are performed on materials of different sizes.

Description

technical field [0001] The invention relates to the construction field, in particular to a crushing device for building materials. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines and equipment. Among them, "housing construction" refers to projects that have roofs, beams, walls, foundations, and can form internal spaces to meet people's needs for production, living, learning, and public activities. [0003] In the current construction field, the generation of construction waste is huge, after the construction waste is generated. Due to the large volume of construction waste, the construction waste needs to be preliminarily crushed before the construction waste enters the processing, which is convenient for the further processing of the construction waste. The application number is 20...

Problems solved by technology

Due to the large volume of construction waste, the construction waste needs to be preliminarily crushed before the construction waste enters the processing, which is convenient for the further processing of the construction waste. The application number is 201710872339.4, which discloses a recycling and crushing device for construction materials, which uses various mechanical structures to process the waste. For crushing, the structure is complex and the operation is troublesome. The most important thing is that the garbage is a one-way operation from feeding to discharging every time. Some garbage often slips directly when the speed is fast, resulting in incomplete crushing.
