Efficient rebar derusting device

The invention discloses an efficient rebar derusting device which comprises a working table, iron wire rollers and a limiting plate. The working table is provided with two layers, a long hole is formed between the planes of the two layers of the working table, dust covers are arranged on the upper portion and the lower portion of the long hole, the front end faces and the rear end faces of the dust covers are provided with two inlets and outlets, and three iron wire rollers are arranged in the dust covers. The first iron wire roller is arranged above the upper layer plane of the working table, the second iron wire roller is arranged between the two layers of planes of the working table, the third iron wire roller is arranged below the lower layer plane of the working table, and iron wires on the sides of the three iron wire rollers are in contact with each other. The side of the upper dust cover is provided with a motor and a transmission device, the transmission device is connected with the three iron wire rollers, the bottom of the lower dust cover is provided with a discharging port, and the limiting plate is horizontally placed above the inlets. The efficient rebar derusting device is simple to manufacture and low in cost; the double-layer working table performs derusting simultaneously; a limiting device causes rebars to enter orderly, the working efficiency is high, the derusting effect is good, the derusting labor cost is reduced, and the working difficulty is reduced.
