Technical Field

[0001] The invention relates to the technical field of mixing devices, in particular to a grouting machine for tunnel construction. Background Art

[0002] In tunnel construction, the grouting machine is an important equipment used for grouting reinforcement of soil or rock. Grouting is to inject specific materials (such as cement slurry, polymer, etc.) into underground voids or holes to enhance the stability and bearing capacity of the geological layer; the grouting machine usually first adds slurry raw materials for mixing, and then injects the mixed slurry into the tunnel.

[0003] Grouting materials are divided into organic and inorganic types. At present, the mixing of grouting materials is mainly carried out by a mixer. The existing mixing equipment has a single mixing method and low mixing efficiency. At the same time, due to the high viscosity of the grouting material, the inner wall of the mixing barrel usually sticks to a part of the grouting material, and the grouting material will adhere to the inner wall of the mixing barrel after drying and cracking, affecting the rotation of the stirring rod. Therefore, in view of the above situation, it is urgent to develop a grouting machine for tunnel construction to overcome the shortcomings in current practical applications. Summary of the invention

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] When the device is running, the raw materials are placed inside the fusion cylinder, and the stirring assembly can stir the raw materials inside the fusion cylinder. The differential transmission control assembly drives the variable support assembly. The variable support assembly cooperates with the mounting seat to not only support the stirring assembly, but also cooperates with the differential transmission control assembly to realize the lateral and longitudinal movement of the stirring assembly. The two movements are carried out simultaneously, and the longitudinal reciprocating movement is faster than the lateral reciprocating movement, so that the stirring assembly moves in a wave shape inside the fusion cylinder. At the same time, the differential transmission control assembly can drive the fusion cylinder to rotate, and cooperate with the moving stirring assembly to fully stir the raw materials inside the fusion cylinder in all directions, thereby ensuring the comprehensiveness of the stirring.
