Abstract

The invention discloses a wet dust-free concrete injection machine, which belongs to the technical field of engineering construction machines, and comprises a chassis, an injection machine, a lower dust box, an upper dust box, a dust absorption fan, an air flue, a dust removal box and a motor, wherein the dust removal box, the motor and the lower dust box are arranged on the chassis, the dust removal box is adjacent to the motor, the motor is adjacent to the lower dust box, the dust absorption fan is arranged above the motor, the upper dust box is arranged above the lower dust box, the dust absorption fan is communicated with the upper dust box and the lower dust box through the air flue, and the injection machine is arranged in the lower dust box. The invention solves the deficiencies of high dust concentration and large labor intensity of workers in the prior art, and high cost and complicated process of the wet injection machine, and the wet dust-free concrete injection machine adapts an operating manner of the conventional injection machine, and has the advantages of high working efficiency, low cost, no dust, convenience for operation and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of engineering construction machinery, and in particular relates to a tidal type concrete dust-free spraying machine. Background technique [0002] Concrete spraying machine is a machine that uses compressed air to continuously transport concrete along the pipeline and spray it onto the construction surface. There are two types of dry jetting machine and wet jetting machine. The former is pneumatically conveying the dry mixture, mixed with pressure water at the nozzle and sprayed out; the latter is conveying the concrete mixture by pneumatic or concrete pump and spraying out through the nozzle. It is widely used in the lining construction of underground engineering, shafts, tunnels, culverts, etc. [0003] Concrete shotcrete machines are widely used in roadway support in traffic, mines, etc. However, due to the dry concrete shotcrete machines commonly used at present, a large amount of mixed dust such as wa...
