Background

Under the limited earth resource environment, the utilization of the three wastes is the key point of the current industry and is also the direction of the utilization and development of future materials. Solid waste utilization is an important component of the method. The crushing and decomposition of reinforced concrete blocks and large-volume stone blocks are an important subject. At present, the concrete pile head is cut by manual simple cutting or explosion treatment mostly, and the concrete pile head is also cut by adopting a front-mounted impact hammer of a crawler excavator, but the front-mounted impact hammer of the crawler excavator is mostly used for the damage of a plane asphalt pavement. Foreign countries have special integrated equipment, but the structure is simple and bulky, and the price is high. At present, the special tool does not appear in China; after the concrete beam column and concrete pile head are simply cut or exploded into blocks, the blocks are crushed by a hammer crusher, screened by a linear screen, sorted by a magnetic roller belt, and selected to be a ferrite material as a waste steel raw material, and the concrete powder is used as a cement material or a building brick. The concrete is a main process for utilizing the concrete at present, and has the advantages of long flow, low efficiency, high mechanical failure rate and high energy consumption; the crushing of the large-block masonry materials, rocks, ores and coal mostly adopts manual hammering, the working environment is severe, the labor intensity is high, the time and the labor are wasted, and the efficiency is low. The crawler front-mounted impact hammer is the best crushing tool at present, but the crawler front-mounted impact hammer is more suitable for plane crushing due to a single cylinder and single rod, is not high in efficiency, is not suitable for vertical plane crushing, and is easy to shake a bottom foundation.

Disclosure of Invention

The utility model aims to provide a reinforced concrete solid waste decomposition device, which solves the problems of crushing and decomposition of waste reinforced concrete column blocks and large-volume stone blocks; the decomposition efficiency is improved, and the labor intensity is reduced.

The utility model discloses a: the device comprises a first frame 1, a second frame 2, a hydraulic cylinder 3, a triangular pendulum body 4, an air pick 5 and gnawing teeth 6. The frame I1 and the frame II 2 are of split structures, are welded in a split mode and are connected through bolts; the tail part of the hydraulic cylinder 3 is connected to the second frame 2, and a push rod of the hydraulic cylinder 3 is connected with the triangular pendulum body 4. The tail part of the hydraulic cylinder 3 is hinged with the second frame 2 to allow the movement of the push rod; one corner of the triangular pendulum body 4 is hinged on the second frame 2, one corner is hinged with a push rod of the hydraulic cylinder 3, and the other corner is connected with the air pick 5. The triangular pendulum body 4 drives the air pick 5 to swing in a large angle along the fixed shaft along with the extension and contraction of the push rod; the bottom of the pneumatic pick 5 is fixed on the triangular pendulum body 4, and the head is hinged with a gnawing tooth 6. The air hammer in the air pick does reciprocating motion, the pick rod is knocked to vibrate, and the pick rod drives the gnawing teeth 6 to damage the large-scale brittle solid structure. The frame I1, the frame II 2 and the triangular pendulum body 4 are welded in a box shape. The hydraulic cylinder 3, the triangular pendulum body 4, the pneumatic pick 5 and the gnawing teeth 6 form an operation unit, 12 operation units are arranged in total, the unit clusters are distributed in a rectangular mode, and 3 operation units are arranged on each side. The gnawing teeth 6 of the symmetrical units are correspondingly meshed and distributed with the edge teeth on the toothed plate.

The solid waste decomposition device consists of 12 operation units. And relatively operating the operation units synchronously, and crushing and separating the solid wastes clamped in the middle. If the solid waste is reinforced concrete, the concrete is crushed, the reinforcing steel bars are not broken, and the purposes of crushing and separating are achieved. And starting different numbers of operation units according to the diameter and the shape and the size of the solid waste.

For the pile head or the vertical concrete beam, the crane can perform the hanging operation; the horizontal cross beam and the ring beam can be fastened on the excavator operating arm through bolts, a scaffold does not need to be additionally erected or destructively separated, and the disassembly operation is convenient. The purposes of improving the decomposition efficiency, performing protective decomposition and reducing the labor intensity are achieved.

The utility model has the advantages of, reduce cutting, hoist and mount process, replace the concrete crushing, screening flow, reduction in production cost.
