Description

Technical Field

[0001] The utility model belongs to the technical field of concrete, in particular to a nozzle device for shotcrete. Background Art

[0002] The spray nozzle system for shotcrete plays a key role in construction. It primarily consists of a nozzle body, an accelerator dosing unit, and related control and connection components. The nozzle body is typically ingeniously designed to spray concrete evenly under pressure at a specific speed and angle, ensuring a uniform and firm coating of concrete on the construction surface. The accelerator dosing unit adds accelerator to the concrete as needed, accelerating its setting and improving construction efficiency and quality.

[0003] There is a significant problem with the existing device during actual use, that is, the angle of the nozzle is in a fixed state. This fixed nozzle angle greatly limits the worker's operational flexibility, making it impossible for the worker to freely adjust the angle according to the actual work scenario and needs when using the nozzle, and thus unable to perform related operations more conveniently. In this way, the worker not only needs to expend more physical strength and energy, and the labor force increases significantly, but also leads to a significant reduction in overall work efficiency, seriously affecting the progress and quality of work.
