Concrete knockout device for recycling waste steel bars on construction site

Abstract

The invention relates to the field of construction site waste material recycling, in particular to a concrete knockout device for recycling waste steel bars on a construction site. The concrete knockout device comprises a workbench, a knockout device body, a straightening device, a waste collecting device and a control cabinet; the knockout device body is arranged at one end of the workbench, the knockout device body comprises a power mechanism and a propelling mechanism, the power mechanism is arranged at one side of the workbench, and the propelling mechanism is arranged at the side, close to the workbench, of the power mechanism; the straightening device is arranged at the end, away from the knockout device body, of the workbench, the straightening device comprises a straightening mechanism, an anti-skid mechanism and a guide mechanism, the straightening mechanism is arranged at the end, away from the knockout device body, of the workbench, the anti-skid mechanism is arranged in the straightening mechanism, and the guide mechanism is arranged at the side, away from the knockout mechanism, of the straightening mechanism; and the waste collecting device is arranged at the bottom of the workbench . The concrete knockout device solves the problems that concrete on the surface is difficult to remove, the correction effect is poor, and time and labor are wasted due to the fact that some existing construction site waste steel bar recycling methods adopt manual hammering with a hammer.

Description

technical field [0001] The invention relates to the field of recycling waste materials at construction sites, in particular to a concrete knockout device for recycling waste steel bars at construction sites. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. Steel bars for reinforced concrete refer to the straight or coiled steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar. The delivery state is straight bar and coiled round. Light round steel bars are actually small round bars and discs of ordinary low carbon steel. Deformed bars are ribbed bars on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length. Steel bars mainly bear tensile stress in ...

AI Technical Summary

Problems solved by technology

[0003] During the renovation of shantytowns, the solid waste from house demolition includes a large amount of waste steel bars. Due to long-term use or external force during house demolition, these waste steel bars will be bent and deformed, and the surface will be covered with concrete. The existing Some methods of recycling waste steel bars on construction sites use manual hammering, which is difficult to remove the concrete on the surface, and the correction effect is poor, time-consuming and labor-intensive
