Device for crushing concrete and separating reinforcing steel bars

Abstract

The invention discloses a device for crushing concrete and separating reinforcing steel bars. The device comprises a rack, a conveying mechanism, a cutting mechanism, a stamping crushing mechanism, an extrusion crushing mechanism and a reinforcing steel bar guiding-out mechanism, wherein the conveying mechanism is arranged on one side of the rack, the cutting mechanism is arranged on one side of the conveying mechanism, the stamping crushing mechanism is arranged on one side of the cutting mechanism. The extrusion crushing mechanism is arranged on one side of the stamping crushing mechanism, and a steel bar guiding-out mechanism is arranged on one side of the extrusion crushing mechanism. The cutting mechanism is additionally arranged to release the internal stress of the concrete block, meanwhile, a pit is formed for follow-up stamping, the crushing cone directly acts on the pit, concrete is pressed and then stamped, and therefore the situation that the concrete disintegrates can be effectively prevented, after concrete is fully crushed through the cutting mechanism, the stamping crushing mechanism and the extrusion crushing mechanism, the concrete and steel bars are separated on the strip-shaped plate, the steel bars are left on the strip-shaped plate and are rapidly guided out through the steel bar guiding-out mechanism, and then the application range of the equipment is enlarged.

Description

technical field [0001] The invention belongs to the technical field of concrete recycling equipment, in particular to a device for breaking concrete and separating steel bars. Background technique [0002] When buildings are demolished or repaired, a large amount of construction waste mainly composed of reinforced concrete will be generated. Crushing, sorting and recycling reinforced concrete can not only solve the problem of environmental damage, but also save resources. carry out recycling; [0003] After searching the patent authorization announcement number: CN108283984B, a reinforced concrete separator, including a casing, one side of the casing is provided with a feed port, and the side of the casing away from the feed port is provided with a discharge port. There is a separation and crushing device for separating concrete and steel bars. The separation and crushing device includes a stamping mechanism that is sequentially arranged in the casing from the feed port to ...

AI Technical Summary

Problems solved by technology

[0004] It has the following problems: 1) The concrete is directly crushed by its stamping mechanism, so that the pointed cone directly acts on the concrete. Since the concrete is hard and is not fixedly conveyed during the transmission process, the direct stamping and crushing can easily cause the concrete to collapse. 2) After the concrete is separated from the steel bar and the concrete is screened out by the vibrating screen mechanism, the steel bar is still trapped inside the equipment and has not been exported, which narrows the scope of application of the equipment, which is not conducive to popularization and use.
