Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to building material mixing and spraying equipment. Background Art

[0002] The spraying of building materials, especially in the field of construction and civil engineering, mainly refers to the sprayed concrete technology. This technology uses specific mechanical equipment to spray concrete materials onto the surface of the structure that needs to be reinforced or supported, so as to enhance the stability of the structure and improve the construction efficiency. The sprayed concrete technology is widely used in many fields such as tunnel support, water conservancy and hydropower, slope support, mining, underground engineering, engineering repair, etc. In tunnel engineering, sprayed concrete, as a support method in the early stage of excavation, plays an important role in improving the overall stability and strength of the tunnel structure.

[0003] When the existing construction material spraying device is working, the unused concrete material in the delivery pipe may solidify, which will cause the nozzle to fail to spray out the construction material. During construction work, workers are often required to carry the spraying pipe to control the spraying direction, which puts great pressure on the workers and is more laborious to adjust the spraying direction.
