Description

Mortar spraying equipment

Technical Field

Background

The mortar spraying machine is also called as a guniting machine, is mechanical equipment for spraying concrete or other materials, and is widely applied to protection projects such as tunnels, culverts, subways, bridges, coal mines, high-biogas mines, hydroelectric projects, underground projects, constructional projects and the like. The main functions of the device are preventing sand and soil from falling off from the inner wall of the tunnel, landslide and collapse, and being used in spray forming or repairing refractory materials of various industrial kilns. The guniting machine utilizes compressed air to continuously convey concrete along a conveying pipeline through a material cavity and spray the concrete onto a construction surface, so that a compact concrete supporting layer is formed. Concrete sprayers can be classified into three types of dry type, wet type and semi-wet type between them according to construction processes, and common types include dry type concrete sprayers, wet type concrete sprayers and the like. Among them, a dry type mortar sprayer is one of the common construction equipment. Traditional dry-type guniting machine relies on artifical material loading generally, and inefficiency, and because the feed inlet of material possesses certain height, when the material loading wastes time and energy, produces a large amount of dust easily, causes serious influence to construction environment and workman's health. Therefore, the mortar spraying equipment provided by the utility model is convenient for feeding, has a dustproof function, and has important significance for improving feeding efficiency, saving labor force of workers and reducing environmental pollution.

For the problems in the related art, no effective solution has been proposed at present.
