Description

A concrete spraying machine

Technical Field

The utility model relates to the technical field of shotcrete spraying machines, in particular to a concrete shotcrete spraying machine.

Background Art

Concrete spraying machine is a machine that uses compressed air to continuously transport concrete along the pipeline and spray it onto the construction surface. It is suitable for various construction projects, whether it is large-scale projects such as bridges, tunnels, subways, or small-scale projects such as civil construction and decoration. Concrete spraying machine can spray concrete materials evenly onto the surface of the building to form a dense and solid protective layer, thereby improving the building's compressive strength, impact resistance and corrosion resistance, and extending the service life of the building. It has a highly efficient spraying ability, which can greatly improve construction efficiency, shorten construction period, and reduce labor costs.

At present, the concrete spraying machine of the prior art requires a transport vehicle to add the mixed concrete to the spraying machine during use. During the transportation process, the concrete may solidify into blocks, which makes it impossible to spray out and causes the spraying pipe to be blocked. After the construction is completed, if the concrete remaining in the spraying pipe and the concrete box is not cleaned up in time, the concrete will slowly solidify. The solidified concrete needs to be cleaned up when the spraying machine is used next time, which increases the labor cost of personnel and reduces the construction efficiency.
