Construction waste environment-friendly crushing device

Abstract

The invention discloses a construction waste environment-friendly crushing device. The device comprises a base; a first stand column is arranged at the left end of the base; second stand columns are respectively arranged at the right end, the front end and the back end of the base; a crushing cylinder is arranged between the first stand column and the second stand columns; a driven gear is arranged on the outer wall of the crushing cylinder; a second motor is arranged at the top end of the second stand column at the right end; a driving gear matched with the driven gear is mounted on a motor shaft of the second motor; the crushing cylinder is mounted on a support column through a roller; multiple cylinder crushing rods are uniformly arranged on the inner wall of the crushing cylinder; a first motor is arranged in middle of the base, and is connected with a rotating rod; multiple rotary crushing rods staggered with the cylinder crushing rods are uniformly arranged at the upper part of the rotating rod; an opening of the crushing cylinder is connected with a crushing plate through a hinge; and the crushing plate is connected with a hydraulic cylinder. The device primarily crushes construction wastes by the crushing plate, and then, further crushes the construction wastes by the crushing rods, so that the crushing efficiency is high, the crushing effect is good.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an environmental protection crushing device for construction waste. Background technique [0002] With the improvement of urbanization and the continuous transformation of old urban areas, old buildings are demolished almost every day, and most of the construction waste is transported to the suburbs or villages without any treatment, and is piled up or landfilled in the open air. It not only consumes a large amount of land and construction costs such as land acquisition, but also causes a huge waste of resources. If these building demolition objects can be reused, the high cost of handling will be avoided, the cost will be saved, and it can be remade into concrete for on-site reuse. [0003] The construction waste generated in construction projects is often large in size, and it is difficult to place it in the crushing cylinder for crushing. However, the current garbage sh...

[0003] The construction waste generated in construction projects is often large in size and difficult to place in the crushing cylinder for crushing

However, the current waste shredders can only crush small construction waste, and do not screen the crushed waste; some of the crushed construction waste is still large in size, which makes it unfavorable for reuse in the later stage
