Building material processing and screening device

Abstract

The invention belongs to the technical field of engineering, and particularly relates to a building material processing and screening device. The building material processing and screening device comprises a frame body, wherein at least two crushing and stirring units are arranged in the frame body; each crushing and stirring unit comprises a crushing gear, a crushing shaft, a sliding rod, a spring, a rack and an auxiliary gear; the lower end of a rotating shaft of a motor is fixedly connected with a stirring rod; the stirring rod is divided into a straight rod and a bent rod; a primary filter plate is arranged below the stirring rod; and a secondary filter plate is arranged below the primary filter plate. Building materials are fully stirred through the crushing and stirring units, at the same time, the building materials are crushed, the stirring effect is enhanced through the stirring rod, the building materials are screened through vibration of the primary filter plate and the secondary filter plate, blockage of the building materials is effectively prevented, meanwhile the screening efficiency is high, and the stirring and crushing role is played in the screening process. Thebuilding material processing and screening device is high in screening efficiency and not prone to damage in the screening process.

Description

technical field [0001] The invention belongs to the field of engineering technology, in particular to a building material processing and screening device. Background technique [0002] Building materials are a general term for materials used in civil engineering and construction engineering, which can be divided into structural materials, decorative materials and some special materials; structural materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, Engineering plastics, composite materials, etc.; decorative materials include various coatings, paints, coatings, veneers, tiles of various colors, glass with special effects, etc. Most building materials need to be screened during use to select the most suitable size. [0003] There is also a technical solution for building material processing and screening in the prior art. For example, a Chinese patent with application number 2016204858478 discloses a building material processing screening d...
