Tidal concrete dust-free sprayer

Abstract

The invention relates to a tidal concrete dust-free jetting machine, belonging to the technical field of engineering construction machinery, comprising a chassis, a jetting machine, a lower dust collection box, an upper dust collection box, a dust suction fan, an air duct, a dust removal box, and a motor. The chassis is provided with a dust removal box, a motor and a lower dust collection box, the dust removal box and the motor, and the motor and the lower dust collection box are arranged adjacently, a dust suction fan is arranged above the motor, and an upper dust collection box is arranged above the lower dust collection box. The dust suction fan communicates with the upper dust collection box and the lower dust collection box through an air duct, and the lower dust collection box is equipped with a jet machine; the invention solves the problems of high dust concentration, high labor intensity of workers, and wet Due to the shortcomings of high cost and complicated process of the jetting machine, it adapts to the operation mode of the traditional jetting machine, with high work efficiency, low cost, dust-free, convenient 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...

AI Technical Summary

Problems solved by technology

[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 water mixture is produced during work, especially the concentration of respirable dust is high, which seriously It affects the health and safety of workers. With the development and progress of society, the country pays more and more attention to the prevention of occupational diseases. For this reason, the country recommends the use of wet jet machines with high cost and complicated procedures to replace dry jet machines as a transitional product
