Concrete crushing device with metal part recovery function

Abstract

The invention discloses a concrete crushing device with a metal part recovery function. The concrete crushing device comprises a box body. The top of the box body communicates with a feeding hopper. Symmetric crushing rollers are arranged at the position, located below the feeding hopper, in the box body. A grinding roller is arranged below the crushing rollers, and the outer side of the grindingroller is sleeved with a grinding cover. According to the concrete crushing device, the symmetric crushing rollers are arranged, large concrete is fast crushed, meanwhile, metal parts are exposed, andsubsequent separation is facilitated; and the concrete crushing device is provided with the grinding roller and the grinding cover with screen holes, concrete blocks are extruded and crushed, the metal parts are separated from crushing residues, the metal parts and the concrete crushing residues are screened and finally separated through a screen plate vibrating up and down, and concrete block efficient crushing and metal part recycling are achieved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a concrete crushing device with the function of recycling metal parts. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. Metal parts such as steel bars or iron sheets are generally nested in the concrete blocks of traditional buildings. If the construction waste is not recycled, it will cause waste of steel. However, recycling is very troublesome. The traditional way is to rely on manual labor. Using tools such as hammers to hammer concrete blocks consumes a lot of labor but the efficiency is very low, the recycling cost is too high, and it is not worth promoting; in addition, there are metal parts nested in the concrete blocks, which is not conducive to the trans...

Problems solved by technology

Metal parts such as steel bars or iron sheets are generally nested in the concrete blocks of traditional buildings. If the construction waste is not recycled, it will cause waste of steel. However, recycling is very troublesome. The traditional way is to rely on manual labor. Using tools such as hammers to hammer concrete blocks consumes a lot of labor but the efficiency is very low, the recycling cost is too high, and has no promotion value; in addition, there are metal parts nested in the concrete blocks, which is not conducive to the transportation and further processing of the concrete blocks , easy to damage processing machinery
