Abstract

The invention provides a wet-type concrete spray unit comprising a feeder and a sprayer. The feeder comprises a magnetic starter I, a feeder hopper I, a feed motor I, a screw feeding device, a water adder, and an accelerator pump adder, wherein the magnetic starter I, the feeder hopper I and the feed motor I are disposed on a frame I. The sprayer comprises a vacuum magnetic starter II, an air supply system, a motor II, a reducer, a hopper II, a rotor assembly, a sealing device, a spray device, and a frame II, wherein the hopper II is a vibrating hopper and is effectively linked with the sprayer through an automatic feeding device. The novel wet-type concrete spray unit has the advantages that resilience rate in spraying is low, spray pulse is low, operation dust is little, a spray layer is high in strength, one-time spray thickness is large, time is saved, and mechanical operating level is high.

Description

technical field [0001] The invention relates to mining machinery equipment, in particular to a novel high-efficiency wet-type concrete spraying unit adopting high-pressure airflow and rotary cutting direct blowing type, mainly used for concrete spraying operation. Background technique [0002] Over the years, dry concrete spraying machines have been widely used in our country. Due to the extremely short mixing time of the mixture and water, and the difficulty of accurately controlling the amount of water added, the dust concentration during the spraying operation is relatively high, the rebound rate is high, and the strength of the concrete is low, especially the problem of high dust concentration. It has become the main obstacle to further popularize the bolt-shotcrete support. Contents of the invention [0003] Aiming at the problems of high dust concentration, high rebound rate and low concrete strength during spraying operation, the purpose of the present invention is...
