Abstract

The invention relates to a concrete wet type injection system. The system comprises a feeding machine, a mixer and a wet type spraying machine that successively connected with each other. The mixer comprises a mixing drum, a strip type stirring vane arranged in the front inside the mixing drum and a helical blade arranged in the back inside the mixing drum, wherein a direction of dip of the strip type stirring vane and a direction of the helical blade are the same. The strip type stirring vane and an axis of the mixing drum form an angle of 10 degrees to 45 degrees; a chain-driven structure and a gear driven structure are arranged in the mixer; and a screw type conveying structure is contained in the mixer. The system provided in the invention is advantaged in small volume, compact structure and reasonable layout, and is capable of realizing integration of feeding, mixing and injection, and greatly improving quality and efficiency of concrete injection at the same time. The system has the characteristics of continuous feeding, continuous stirring, uniform injection, convenient operation and maintenance, and is especially suitable for operation in a small space.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a concrete wet spraying system. Background technique [0002] At present, in order to improve working conditions and increase production efficiency, domestic enterprises use equipment such as feeders, mixers, and wet spraying machines when spraying concrete, but each equipment is often an independent unit. It takes up a lot of space and is difficult to adapt to the small space under the mine. On the other hand, because a lot of manual operations are required in the middle of the construction, the degree of automation is low, the production efficiency is not high, and the production capacity consistency between equipment is poor. , it is difficult to ensure the continuity of feeding, the uniformity of stirring and the quality of spraying. [0003] In the field of concrete mixing, due to the advantages of simple structure, reliable operation and convenient maintenance, the dual-con...
