Description

Technical Field

[0001] The utility model relates to the technical field of mining production, in particular to an angle-adjustable shotcrete support machine for mining production. Background Art

[0002] Mining production is a complex process covering multiple links and technologies, involving multiple stages such as exploration, development, and processing of mineral resources. In the mining production process, shotcrete support machines are needed to prevent ore and soil from falling off the inner wall of the tunnel and to prevent landslides and collapses.

[0003] For example, in the concrete shotcrete machine with publication number CN218862626U, concrete can be placed inside the screen frame. Once the driving motor is started, the turntable can be driven to rotate. The rotation of the turntable can drive the connecting rod and the screen frame to move. Under the elastic force of the gas spring, the continuously rotating turntable can shake the screen frame up and down, sifting the fine concrete into the inside of the feed chamber and blocking the stones in the concrete so that subsequent users can clean up large impurities such as stones. The second start of the driving motor can drive the mixing frame to rotate, and the scraper on the mixing frame moves. The concrete on the inner wall of the sticky processing box is scraped off by rotating to reduce the concrete from sticking into blocks for a long time. Subsequently, the concrete is sucked out by the material pump in the discharging mechanism and sprayed out through the spraying pipe. Under the action of the feeding pipe, the concrete is transported through the feeding pipe and the hose. In order to reduce the excessive shaking of the spraying machine during operation, the inner thread groove of the thread groove plate allows the user to rotate the threaded rod downward, and the positioning plate is used for positioning and anti-slip. The vibration damage to the ground caused by the operation of the spraying machine is reduced by the setting of the shock-absorbing pad.

[0004] When the above technical solution is in use, concrete is sprayed out through a spray pipe to achieve spraying work on the wall. However, since the angle of the spray pipe is fixed, it is easy for the spraying concentration to be too high at a certain point, resulting in waste of slurry, thereby increasing production costs, and at the same time failing to meet the spraying needs of multiple spraying positions.

[0005] Therefore, we proposed an angle-adjustable shotcrete support machine for mining production that can solve the above problems well. Utility Model Content

[0022] (3) The motor drives the stirring rod to rotate, thereby stirring the concrete in the storage tank to prevent it from sticking together due to long-term storage;

[0023] Furthermore, when the stirring rod rotates, it can drive the two scrapers to move along the inner wall of the storage tank, thereby scraping off the residual concrete on the inner wall of the storage tank, making it easier to clean the storage tank later. BRIEF DESCRIPTION OF THE DRAWINGS
