Abstract

The invention relates to the technical field of concrete construction, in particular to a jet device, a spray head assembly and a concrete jet vehicle. The jet device comprises a jet nozzle and a mixing device connected with the jet nozzle, and a clamping device for tightly clamping the jet nozzle is arranged at the position where the mixing device is connected with the jet nozzle. The mixing device comprises a casing pipe and a mixer, and a cavity is formed between the casing pipe and the mixer. A ventilation pipe is connected to the casing pipe. The spray head assembly comprises a driving device and the jet device, the driving device is connected with the outer wall of the mixing device on the jet device, and the driving device comprises a swinging device and a brushing device. The brushing device comprises a first hanging bracket and a second hanging bracket, the first hanging bracket is connected with the swinging device, and the second hanging bracket is connected with the outer wall of the mixing device through a connection part. The concrete jet vehicle comprises the spray head assembly. The technical problems that a spray head in the prior art is prone to cracking, and theservice life is short are solved.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a spraying device, a spray head assembly and a concrete spraying vehicle. Background technique [0002] Concrete spraying machine is a construction machinery equipment that uses compressed air to continuously transport concrete mixture and sprays it onto the spraying surface to form a supporting structure and strengthen and protect the surface of the building. At present, the commonly used concrete sprayers are dry concrete sprayer and wet concrete sprayer. Among them, the wet concrete spraying machine has been widely used because of its small concrete rebound, low dust content in the air, and low harm to the human body. The nozzle assembly of the existing wet concrete sprayer usually adjusts the position of the nozzle assembly according to the spray surface, and sprays the spray surface continuously after the position is determined, and then moves the nozzle assem...
