Description

Technical Field

[0001] The utility model relates to the technical field of mine support, in particular to a dust-free feeding, stirring and spraying integrated machine for mines. Background Art

[0002] In mining, concrete mixed with cement, sand, stone, water and admixtures is often sprayed into mine tunnels through spraying equipment to achieve stable support for the mine tunnels. The mine shotcrete machine is a mechanical equipment widely used in mine construction, mainly used for spraying concrete to form a support layer.

[0003] The existing patent document CN217681779U discloses a spraying device for mine support, and the protected claim "includes a spraying machine and a movable seat, the spraying machine is installed at the upper end of the movable seat, and the outer side of the spraying machine is integrally connected to a material placement chamber. The mine support spraying device has two sets of feed pipes and nozzles arranged on the outer side of the spraying machine, and through the coordinated use of two sets of support pedals and anti-slip pads on the outer side of the shift plate, it is convenient for users to stand at the front end of the movable seat to perform multi-station double-sided spraying operations, thereby improving the work efficiency of the device during use. At the same time, through the setting of the lifting chamber at the bottom of the support pedal, the standing height of the staff can be stably raised and lowered to facilitate the staff to work at heights, and through the coordinated use of the first sleeve and the second sleeve on the outside of the guardrail frame, the feed pipe and the nozzle can be limited at different angles, so that the staff can perform hand-held operations, reducing the staff's fatigue from long-term lifting of the feed pipe."

[0004] However, the mine support spraying device in the above-mentioned public document mainly considers that two sets of feed pipes and nozzles are arranged in opposite positions on the outside of the spraying machine, and through the coordinated use of two sets of support pedals and anti-slip pads on the outside of the shift plate, it is convenient for the user to stand at the front end of the mobile seat to perform multi-station double-sided spraying operations, thereby improving the work efficiency of the device in use. At the same time, through the setting of the lifting cavity at the bottom of the support pedal, the standing height of the staff can be stably raised and lowered to facilitate the staff to work at high places, and through the coordinated use of the first sleeve and the second sleeve on the outside of the guardrail frame, the feed pipe and the nozzle can be limited at different angles, so that the staff can perform hand-held operations, reducing the staff's fatigue from long-term lifting of the feed pipe. It does not take into account that when the existing spraying machine is in use, the concrete used is mostly mixed and loaded manually by the staff. When manually mixing concrete, the mixing force and speed may be uneven, so the uniformity of the concrete is difficult to guarantee, which may affect the working effect of the spraying machine and may even cause the construction quality to fail to meet the standards. In addition, the dust generated by manual loading will affect the health of the staff. Utility Model Content
