Abstract

The invention relates to a construction waste crusher and belongs to the field of construction equipment. The problem of sieve blocking is solved. The construction waste crusher comprises a shell, wherein the upper end of the shell is provided with a feeding hopper, a first crushing assembly is arranged at the discharging opening of the feeding hopper in a rotating manner, a sieving drum is arranged in the shell in a rotating manner, a first motor is fixedly arranged on the shell, a guide plate is fixedly arranged in the shell, a rotating shaft is arranged in the shell in a rotating manner andlocated above the sieving drum, a rotating drum is coaxially fixedly arranged on the rotating shaft, the rotating drum is of a hollow structure and communicates with the rotating shaft, a brush is arranged on the rotating drum, a fan is arranged on the shell, the fan communicates with the rotating shaft through an air pipe, air outlet holes are formed in the rotating drum, a second motor is arranged on the shell, and a discharging hopper is arranged below the sieving drum. The second motor is started, the second motor drives the rotating shaft to rotate, the rotating shaft drives the rotatingdrum and the brush to rotate, and the brush scrubs the sieving drum, so that the purpose of clearing aggregates blocked in net holes is achieved, the blockage of a sieve net is effectively prevented,and the sieving efficiency is increased.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a construction waste crusher. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. The recycling of garbage and municipal garbage resources can greatly reduce the landfill area of ​​garbage and reduce environmental pollution. [0003] After the crusher crushes the construction waste, it will be sieved through the screen. Due to the limited mesh size of the screen, when sieving aggregates, it is easy to cause blockage of the mesh and reduce the screening efficiency of the screen. [0004] The Chinese patent application publication number CN108080078A discloses a two-stage environment-friendly construction waste crusher, which includes a housing, a feeding h...
