Embodiment 1

[0031] The anti-stick sprinkler system provided by this embodiment includes a sprinkler assembly and a concrete anti-stick layer, wherein the concrete anti-stick layer is arranged on the outer surface of the sprinkler assembly, and the adhesion between it and the concrete is higher than that between the concrete and the outer surface of the sprinkler assembly. When the sprinkler system is working, the sprayed concrete directly acts on the concrete anti-adhesive layer on the outer surface of the sprinkler assembly. When the concrete solidifies and the concrete anti-adhesive layer accumulates to a certain extent, the weight of the concrete will exceed that of the concrete. The adhesion between the anti-sticking layer and the concrete, and then the concrete will fall off automatically, reducing the concrete accumulation on the anti-sticking sprinkler system and the required cleaning frequency, and ensuring the performance of the anti-sticking sprinkler system and the boom system co...

Embodiment 2

[0058] This embodiment provides a concrete shotcrete truck, including the anti-stick sprinkler system described in any one of the foregoing embodiments.

[0059] The technical effect of the concrete shotcrete vehicle provided in this embodiment is the same as the technical advantage of the above-mentioned anti-stick sprinkler system, and will not be repeated here.

Abstract

The invention relates to an anti-sticking spraying head system and a concrete grout spraying vehicle, and relates to the technical field of engineering machinery. The anti-sticking spraying head system comprises a spraying head assembly and a concrete anti-sticking layer; and the concrete anti-sticking layer is arranged on the outer surface of the spraying head assembly and used for preventing concrete from being accumulated on the spraying head assembly. The technical problem that in the prior art, a spraying head system is prone to being subjected to concrete accumulation, and consequently use performance of the spraying head system is affected is relieved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to an anti-sticking nozzle system and a concrete spraying vehicle. Background technique [0002] Concrete spray truck is a kind of support equipment widely used in tunnels or other projects. At present, concrete spray trucks usually use hydraulic pumping system, and the nozzle system installed at the end of the pumping pipeline is constructed through the boom system. On the working surface, because the sprinkler system is close to the construction surface and the working environment is harsh, the sprayed concrete often accumulates on the sprinkler system, which directly affects the performance of the sprinkler system, boom system, and even the entire vehicle of the concrete spraying truck. If there is no quick cleaning , It is very easy to force the nozzle system to often cause sticking, blockage, etc., so it is necessary to clean the nozzle system frequently. At the...
