Mobile spraying device for wall body

Abstract

The invention relates to spraying equipment, in particular to a mobile spraying device for a wall body, which is used for spraying lime-sand mortar and putty to wall bodies of mine tunnels and buildings. The invention provides the mobile spraying device for the wall body with the advantages of simple structure, convenience in operation, low production cost and high spraying efficiency. The technical scheme adopted by the invention is that a supporting platform is arranged on a mobile cart; a feed delivery pipe is arranged on the supporting platform in a supporting manner; a hopper is arranged on the top of the feed delivery pipe; the bottom of the hopper is communicated with the feed delivery pipe; a feed pushing shaft with a helical blade is arranged in the feed delivery pipe; a conveying motor for driving the feed pushing shaft to rotate is arranged at one end of the feed delivery pipe; a discharging pipe is vertically arranged at the other end of the feed delivery pipe and below the feed delivery pipe; a spraying head is connected to the the discharging pipe through a universal ball; a compressed air outlet pipe is arranged in the spraying head. The mobile spraying device disclosed by the invention has the advantages of simple structure and convenience in use, and is widely used for spraying the lime-sand mortar and the putty.

Description

technical field [0001] The invention relates to a spraying equipment, in particular to a mobile wall spraying device for spraying sand ash and putty on mine tunnels and building walls. Background technique [0002] At present, the sand ash and putty of the known body of wall mostly adopt artificial brushing, straight brushing or spray gun spraying. The speed of manual brushing and straight brushing is slow and consumes a lot of man-hours; the existing spray gun spraying uses at least 20kg / cm 2 High-pressure pipes are used to transport materials under high pressure, and manual hand-held spray guns are used for spraying. The cost is high, the construction height is limited, there are many wearing parts, and it is easy to block. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art, and the technical problem to be solved is to provide a mobile wall spraying device with simple structure, convenient operation, low production cost and high...
