Abstract

The invention discloses a crushing and screening device for construction waste, which comprises a bottom plate, a left side plate, a right side plate, a top plate, a transmission mechanism, a first connecting rod, a second connecting rod, a first sliding sleeve, a vertical sliding rod, a horizontal Rod, third connecting rod, crushing plate, second sliding sleeve, L-shaped rod, crushing frame, slide block, slide rail, discharge pipe, fourth connecting rod, screen mesh, screen box and collection frame, the present invention provides There is a transmission mechanism. The transmission mechanism includes a mounting plate, a motor, a first disc, a mounting shaft, a first gear, a second disc and a second gear. Through the cooperation of the above components, the crushing plate can crush the construction waste in the crushing frame. The structure is simple and the working efficiency is high. At the same time, the crushing frame moves left and right, and the garbage in the crushing frame is constantly turned, so that the crushing is more uniform and thorough, and the crushing efficiency is further improved. There is a fourth connecting rod, a screen and a screen box. The above components work together to drive the screen to move left and right to prevent the screen from being blocked and improve the screening efficiency.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a crushing and screening device for construction waste. Background technique [0002] Construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. Classified by source, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0003] Coarse and fine aggregates are produced from waste building concrete and waste masonry, which can be used to produce concrete and mortar of corresponding strength levels or to prepar...
