Description

Technical Field

[0001] The utility model relates to the technical field of wet spraying machines for mines, in particular to a high-efficiency self-cleaning device for wet spraying machines. Background Art

[0002] A mining shotcrete machine is a type of equipment specifically designed for underground construction in coal and other mines, primarily used for wet concrete spraying. This equipment ensures uniform mixing of the mixture and accurately controls the water-cement ratio, facilitating cement hydration, thereby reducing dust and rebound, and improving the quality and strength of the concrete. Mining shotcrete machines are widely used in shotcrete construction in railways, tunnels, subways, hydropower projects, underground engineering projects, and underground mines. The main advantages of mining shotcrete machines include: Reduced equipment movement: Suitable for use in narrow tunnels and locations inaccessible to equipment and materials in coal mines, this reduces equipment movement, reduces worker workload, and improves work efficiency. Reduced dust concentration: By reducing dust and rebound, workers' physical and mental health are protected, meeting the mine's requirements of "reduced staff, safety, high production, and increased efficiency." Fully explosion-proof design: The entire machine is explosion-proof and carries a coal mine safety certificate, ensuring safety during underground use. The use of mining shotcrete machines is not limited to underground mines. It can also be used in large tunnels, hydropower stations, slope protection and other working environments with large concrete shotcrete projects, demonstrating its wide applicability and importance.

[0003] After the mixing barrel of the spraying machine has been used for a long time, the slurry inside the mixing barrel accumulates and solidifies, which is difficult to clean. Therefore, the mixing barrel of the spraying machine needs to be cleaned.

[0004] The existing patent publication number is CN210660125U, which discloses a wet hydraulic concrete shotcrete machine for mining, including a base and a spray gun. The upper surface of the base is fixed with a high-pressure water pump, a raw material tank, and a mixing tank. The water outlet of the high-pressure water pump is connected to the mixing tank, and the top of the mixing tank is connected to the raw material tank. A feeding device is provided at the bottom of the raw material tank. The top of the mixing tank is connected to an additive feed pipe. A stirring paddle is provided inside the mixing tank for rotation. A motor is mounted on the outer wall of the mixing tank. The output shaft of the motor is coaxially connected to the stirring paddle. The mixing tank is connected to the spray gun via a hose. High pressure is generated by the high-pressure water pump, and the use of hydraulic pressure improves safety. High-pressure water is used for mixing to ensure a uniform mixture. The advantages of this utility model are simple structure, easy movement, high safety performance, strong spraying force, and easy promotion and implementation.

Furthermore, slurry can splash onto the machine's surface, causing it to adhere to the outside of the machine, making it difficult for workers to clean. To address this, we propose a highly efficient self-cleaning device for wet spraying machines to address these issues. Utility Model Content
