Description

Technical Field

[0001] The utility model relates to a material stirring device, in particular to an underground ash and sand material stirring machine. Background Art

[0002] At present, commercial concrete is mostly used in the construction of various highway tunnels and railways. The concrete is transported to the site by a mixer truck for spraying. However, the spraying of tunnels in coal mines is carried out hundreds or even thousands of meters underground. Lime sand is mostly used for ground hardening. At present, there is no suitable mixer truck to transport lime sand directly to the mine.

[0003] Therefore, in reality, raw materials are usually transported underground by mine cars, and mixing operations are carried out at the underground work site. However, for ordinary mixers, the mixer outlet is fixed, and after mixing, it needs to be spread to the designated place manually. This method is time-consuming and labor-intensive, extremely inefficient, and inconvenient to use.

[0004] For example, the single-shaft reciprocating mixer with the authorization announcement number CN 103381622 B has a feed port on one side of the mixing drum and a discharge port on the other side. The mixing drum and the feed port and discharge port on both sides form an integrated wing-shaped structure. The discharge port and the mixing drum are integrated, and the discharge angle is constant. Although this mixer can operate underground, it does not have mobility. The discharge still needs to be unloaded to the ground and then manually spread to the designated place, which still requires a lot of manpower and is still inefficient. In addition, the discharge port angle is fixed and cannot be adjusted according to the target location, resulting in poor flexibility. Summary of the invention
