Abstract

The invention discloses a blade type concrete spraying machine. The blade type concrete spraying machine is composed of a machine frame, a spiral conveyer, an accelerating agent pump, a grout spraying machine, wheels and an air compressor. The wheels are mounted under the machine frame. The air compressor, the accelerating agent pump and the grout spraying machine are sequentially mounted on a platform of the machine frame. The spiral conveyor is fixed to the machine frame through two supporting columns. According to the blade type concrete spraying machine, mechanical and electrical integration is well achieved, and the performance is efficient and reliable; and the blade type concrete spraying machine has the characteristics of being compact in structure, easy to mount, convenient to operate and maintain, environmentally friendly, capable of saving energy and the like, and can be widely applied to projects including coal mines, subways, tunnels, high-speed rails, highways and the like.

Description

technical field [0001] The invention relates to a spraying device, in particular to blade-type wet concrete spraying, which is applied to coal mines, subways, tunnels, highways and projects involving concrete spraying. Background technique [0002] Concrete spraying technology is currently divided into dry concrete spraying, wet concrete spraying and wet concrete spraying. Generally, wet concrete spraying is classified as dry concrete spraying. At present, the sprayed concrete used in domestic underground projects is mainly dry spraying. Its advantages are obvious, mainly for less equipment investment and simple process. The conveying distance is long, no conveying restrictions are accepted, sand and gravel can be transported, and the operation and maintenance are convenient. However, there are large dust and high rebound rate. According to measurements, the dust concentration in the spraying operation area is 80-100 mg / m-3, and some are even as high as 1000 mg / m-3; the re...
