A high-rise building waste crushing and conveying device

Abstract

The invention discloses a high-rise building waste material breaking and conveying device. The high-rise building waste material breaking and conveying device comprises a breaking box and multiple conveying pipe sections. The breaking box is fixed to the construction floor, and the conveying pipe sections are downwards laid along an elevator shaft from the construction floor. Material guide blocks, breaking rollers, lug bases, vertical plates, a separating plate, hydraulic push rods, movable rods and multi-tooth cutters are arranged in the breaking box, and coarse material discharging holes are uniformly formed in the middle plate body of the separating plate. Each conveying pipe section comprises a rectangular conveying pipe. An upper end plate and a lower end plate are fixedly arranged at the two ends of each rectangular conveying pipe and connected through multiple buffer springs. A dust guide opening is formed in one narrow edge portion of each rectangular conveying pipe, an outercover with a dust absorption pipe is fixedly arranged on the outer side of each dust guide opening, and unblocking assemblies are arranged in the other narrow edge portion and an inner cavity of eachrectangular conveying pipe. By the adoption of the high-rise building waste material breaking and conveying device, the dust generated in the conveying process can be effectively cleaned away, the phenomenon of the raising dust is avoided, and the environmental protection effect is good; and when the blocking phenomenon appears, a worker only needs to conduct operation outside the conveying pipe sections, the blocking can be rapidly eliminated, the conveying pipe sections do not need to be disassembled, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of high-rise building waste recycling, in particular to a high-rise building waste crushing and conveying device. Background technique [0002] High-rise construction waste includes concrete (concrete that has not been used in engineering), construction debris (mineral materials such as old concrete and mortar produced by chiseling, plastering, etc.), dust, wood, paper, metal and other types of waste. Most of the existing construction waste recovery devices for high-rise building waste use the elevator shaft space to install transmission pipes, and then use the transmission pipes to transport the waste to the ground, and finally transfer to the crushing mechanism for processing. [0003] The patent specification with the publication number CN206823976U discloses a discharge mechanism for a construction waste recovery device, including: a vertical plate, the bottom end of the recovery pipe of the construction...

AI Technical Summary

Problems solved by technology

[0004] The discharge mechanism of the above-mentioned construction waste recovery device has disadvantages in the process of use. First, the waste cannot be quickly crushed before conveying, and the waste is large in size, resulting in a large impact due to the gravitational potential energy of the waste during the conveying process. The second is that the pipeline is not equipped with a buffer mechanism, which is subject to a large impact during discharge and is easily damaged; third, the dust generated during the transportation process cannot be effectively removed, resulting in the occurrence of dust; fourth, there is no Set the dredging component, when the inside is blocked, it cannot be dredged in time, and it needs to be disassembled to perform the dredging operation
