Double crushing device for building materials

Abstract

The invention discloses a double crushing device for building materials. The double crushing device comprises a base, first servo motors, driving gears, transmission gears, a crushing box, a box opening, a transmission belt wheel, a rotary shaft, a crushing wheel, a driving belt wheel, a second servo motor, inclined plates, a grinding box, transverse shafts, a building material outlet, a conveyingdevice, a dedusting broom, fixed blocks, a mounting frame, a conveying wheel, a rotary disc, a belt wheel, a third servo motor, a conveying bracket, a support column and grinding wheels, wherein thegrinding box is arranged in the middle part of the upper part of the base; the first servo motors are respectively arranged at both sides of the grinding box; each driving gear is arranged at one sideof each first servo motor; the output end of each first servo motor is connected with the corresponding driving gear through a coupling; the two transverse shafts are arranged in the grinding box inparallel; each grinding wheel is arranged on each transverse shaft; one end of each transverse shaft is arranged at the side wall of the grinding box, the other end of each transverse shaft penetratesthrough the side wall of the grinding box, and the end surface of each transverse shaft is welded with the corresponding transmission gear.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a double crushing device for construction materials. Background technique [0002] At present, with the development of science and technology, construction and other fields are developing rapidly, and in the field of construction, it is often necessary to crush construction materials. In the crushing process, it is easy to be incompletely crushed, and the work efficiency is poor, which brings a lot of inconvenience to people's later work, and most crushing machines require workers to manually put building materials into the crushing machine entrance, and the work intensity of workers is high. Too close to the crushing machine is prone to accidental damage, so a double crushing device for building materials is proposed. Contents of the invention [0003] The object of the present invention is to provide a double crushing device for building materials to solve the problems ...
