Problems solved by technology
A large amount of dust is generated during the spraying process, and it spreads rapidly due to no effective control measures, polluting the entire tunnel, causing the dust content in the air to seriously exceed the standard, the air quality in the tunnel drops rapidly, and the visibility decreases sharply, forming a major hidden danger to construction safety and causing Serious harm to workers' health and serious environmental pollution
[0003] Defects of the existing technology: the existing spraying equipment does not add any dust-proof and dust-reducing equipment, and the floating dust generated by the spraying machine during the spraying process can hardly be effectively controlled, and all diffuse into the tunnel, resulting in serious air pollution

Embodiment Construction
[0023] Aiming at the characteristics that the current spraying equipment produces a large amount of dust and cannot be collected, the present invention makes the following improvements: in order to collect the dust produced by the spraying equipment, a dust collecting plate 15, a dust collecting cover 16, an upper Devices such as dust guide groove 4, lower dust guide groove 10, dust suction pipe 12 have also improved the sealing between original hopper, hopper and upper pressing plate in addition.
[0024] (1) Improvement on the hopper: the original hopper is a straight-feed hopper, and now the straight-feed hopper is changed to an oblique feed hopper 1, such as figure 1 , 2 shown.
[0025] When the original shotcrete machine feeds, when the rotor body 8 turns between the upper pressure relief port 3 and the feed port 22, the upper pressure relief port 3 will connect with the feed port 22, and part of the high-pressure gas will flow from the feed port 22. When the upper pres...

The invention provides a dust-collecting type slurry spraying machine, which comprises a hopper, a rotor body, an upper pressing plate, a lower pressing plate, an upper pressure release opening and a lower pressure release opening. The dust-collecting type slurry spraying machine is characterized in that: a dust collection plate is arranged between the upper pressing plate and the hopper; a dust absorption pipe is arranged on the dust collection plate; an upper dust guide groove is arranged at the upper pressure release opening; a lower dust guide groove is arranged at the lower pressure release opening; the upper and lower dust guide grooves are respectively fixed on the upper and lower pressing plates; a dust collection hood is arranged around the rotor body; and the dust collection hood is arranged between the lower pressing plate and the dust collection plate. By adoption of the dust-collecting type slurry spraying machine, dust production points of the slurry spraying machine are totally covered, floating dust which is produced by the slurry spraying machine is completely absorbed into the dust absorption pipe and then exhausted, so that the pollution problem of the slurry spraying machine is effectively solved, the incidence rate of occupational diseases is reduced, and a clean construction environment is provided for workers during tunnel construction; moreover, by matching the dust-collecting type slurry spraying machine with a dust remover, the problems of pollution in a hole and pollution diffusion can be effectively solved.
Description
technical field [0001] The invention relates to a spraying machine, in particular to a dust-collecting spraying machine, which is mainly used for tunnel construction. Background technique [0002] The dry shotcrete machines used in tunnel construction have a common feature that the equipment is highly polluted, which is the main source of dust pollution in tunnel construction. A large amount of dust is generated during the spraying process, and it spreads rapidly due to no effective control measures, polluting the entire tunnel, causing the dust content in the air to seriously exceed the standard, the air quality in the tunnel drops rapidly, and the visibility decreases sharply, forming a major hidden danger to construction safety and causing The health of workers is seriously endangered and the environment is seriously polluted. [0003] Defects of the existing technology: the existing spraying equipment does not add any dust-proof and dust-reducing equipment, and the floa...
