Abstract

The invention discloses crushing and screening equipment for construction waste. The crushing and screening equipment comprises a crushing box body, a crushing mechanism and a feeding pipe; the crushing mechanism comprises a fixing box, an air cylinder, a swing rod sliding mechanism and a crushing component; a feeding opening is formed in the feeding pipe, a dust prevention mechanism used for limiting dust flying at the feeding opening is installed in the feeding pipe, wherein a screening mechanism is arranged in the crushing box body; the screening mechanism comprises a motor, a transmission shaft, a first-stage screening plate and a second-stage screening plate; the transmission shaft is sleeved with a transmission assembly; and the second-stage screening plate is obliquely arranged in the crushing box body. Due to the fact that the dust prevention mechanism and the screening mechanism are arranged in the device, construction waste dust at the position of the feeding pipe can be effectively prevented from rising all around, the screening function on construction waste is achieved, and the screening work efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of crushing and screening machines, in particular to construction waste crushing and screening equipment. Background technique

[0002] Construction waste refers to the construction waste produced by man-made or natural reasons in the project, including waste residue, spoil, silt and waste materials, etc. These materials are of no help to the building itself, but they are substances produced during the construction process and need to be treated accordingly so that the ideal project construction can be achieved. Because it is an overall process, so The consideration of its link is more important. With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount of construction waste in China has accounted for more than 1 / 3 of the total urban waste. The existing crushing and screening machines ...
