Construction refuse crushing recycling device

Abstract

The invention discloses a construction refuse crushing recycling device which comprises a base, a support and a top plate. The support is arranged on the base, and the top plate is arranged at the top of the support. A motor is arranged at the left side of the bottom of the top plate and is further connected with a lifting screw rod. The support is provided with sliding rails, and the sliding rails are connected with a first supporting plate and a second supporting plate in a sliding mode. The first supporting plate is provided with a through hole, and the through hole is connected with a first connecting rod in a sliding mode. The bottom end of the first connecting rod is fixedly connected with a pressing plate, and a high-pressure spring is arranged between the pressing plate and the first supporting plate. The second supporting plate is fixedly provided with a material crushing box, and a filtering plate is arranged inside the material crushing box. The bottom of the material crushing box is further connected with a discharging pipe. According to the construction refuse crushing recycling device, the lifting screw rod rotates to drive the pressing plate and the filtering plate inside the material crushing box to be drawn together in the middle, and thus construction refuse can be squeezed and crushed; and the crushed construction refuse is filtered through the filtering plate so as to be squeezed and crushed to be in a fine state continuously, and the phenomenon that the construction refuse is too large and thus later-period recycling cannot be facilitated is prevented.

Description

technical field [0001] The invention relates to construction machinery, in particular to a device for crushing and reusing 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 difficult to crush thoroughly at one time. Part of the crushed construction waste is still large in size, which is not conduciv...

AI Technical Summary

Problems solved by technology

[0003] The construction waste generated in construction projects is often large in size and difficult to crush thoroughly at one time. Part of the crushed construction waste is still large in size, which is not conducive to later utilization; ordinary construction waste treatment has only completed one process, and the crushed construction waste It cannot be used quickly and directly, and the storage and transportation of construction waste will increase the cost of reuse, which is not in line with the concept of environmental protection
