Description

technical field [0001] The invention relates to the technical field of downhole spraying, in particular to a convenient downhole spraying machine for reducing dust and its use method. Background technique [0002] As we all know, the shotcrete machine is a device that sends compressed air to the nozzle through the delivery pipe, and then sprays water onto the construction surface to achieve rapid concrete reinforcement. It is an indispensable mechanical equipment for underground mine construction. The shotcrete machine represents tunnel construction technology. At the leading level, the shotcrete machine is an excellent and advantageous machine used in the construction of wall panels in the construction and construction industry. Although the shotcrete machine can mechanize the process of rough wallboard construction, it saves manpower and improves work effect.

Problems solved by technology

[0003] When the existing spraying machine is in use, it is found that the spraying machine will generate a large amount of dust, which will affect the health of the construction workers. Due to the relatively small and closed space during construction, a large amount of dust will affect the construction line of sight of the personnel, resulting in unsatisfactory construction results. less practical;

[0004] Among the existing solutions, for example, CN102400693A provides a dust-collecting spraying machine, including a hopper, a rotor body, an upper pressure plate, a lower pressure plate, an upper pressure relief port and a lower pressure relief port, and a dust collecting plate is provided between the upper pressure plate and the hopper; A dust suction pipe is installed on the dust collection plate; an upper dust guide groove is provided at the upper pressure relief port, and a lower dust guide groove is provided at the lower pressure relief port, and the upper and lower dust guide grooves are respectively fixed on the upper and lower pressure plates; There is a dust collection cover around the rotor body, and the dust collection cover is installed between the lower pressure plate and the dust collection plate. By covering all the dust production points of the shotcrete machine, all the floating dust generated by the shotcrete machine is sucked into the dust suction pipe and discharged. , which effectively solves the pollution problem of the spraying machine, reduces the incidence of occupational diseases, and provides a clean construction environment for the tunnel construction workers. Larger, higher equipment cost

[0005] Among other solutions, for example, CN212534103U discloses a dust-proof spraying machine, which mainly solves the problem that when the existing spraying machine is depressurized, the cement dust in the material barrel will be discharged with the air pressure, causing dust and air leakage outside the machine. The problem of gas Louis blockage, including the air inlet connected to the second air source and the deflector, an annular air passage is formed between the deflector and the inner wall of the barrel, and the pressure relief port and the annular air passage The air inlet is connected with the annular air channel, and the bottom of the annular channel is provided with a ventilation gap corresponding to the valve assembly, so a dust-proof shotcrete machine is provided, and the gas flows through the air channel The gap prevents the concrete slag from being discharged out of the machine along with the gas, causing the concrete to block the exhaust pipe and control valve and cause dust outside the machine, which affects the environment and the normal work of workers beside the machine. However, this design requires a complicated air circuit Design and annular airway control, so the whole operation process control and structural design are more complicated
