The invention discloses a grouting spray gun for a non-cleaning pneumatic two-fluid grouting pump. The grouting spray gun comprises a valve casing (1), wherein a gas inlet tube joint (2) which is connected with a gas outlet of a pneumatic pump assembly is arranged on the top of the valve casing (1); a discharging tube joint (3) is arranged at the front end of the valve casing (1); a charging tube joint (4) is arranged at the rear end of the valve casing (1); an adjusting mechanism for controlling the smoothness and blockage of material flow and gas flow is arranged inside the valve casing (1); and an operating handle (5) for controlling the adjusting mechanism is arranged outside the valve casing (1). The grouting spray gun has an advanced design, a compact and simple structure, a small size and light weight; a plurality of one-way stop valves are arranged inside the grouting spray gun to satisfy mixing quality; the spray gun does not need to be cleaned by other chemical liquid; after grouting, a gun cleaning gas source ball valve is opened, and the operating handle is rotated by 180 degrees to automatically clean the spray gun for about two minutes, so that the spray gun is not blocked.
Description
technical field [0001] The invention relates to a grouting pump used in engineering, in particular to a grouting spray gun used for a no-cleaning pneumatic double-fluid grouting pump. Background technique [0002] Grouting pumps are widely used in mines, tunnels, water conservancy, subways, buildings, bridges and other construction sites for grouting, water blocking, gap filling, coal seam roof reinforcement, crushing and other projects. Existing grouting pumps have the following disadvantages or deficiencies: [0003] 1. Large volume, heavy weight, inconvenient to carry. [0004] 2. The function is single and the scope of application is narrow. [0005] 3. The grouting spray gun is easy to block and difficult to clean. [0006] 4. It is less safe in an environment where it is flammable and explosive, and the temperature and humidity change greatly. Contents of the invention [0007] In order to solve the deficiencies in the prior art, the present invention provides a ...
