Abstract

The invention provides a monolithic concrete guniting device which is characterized in that the device comprises a car body, wherein a concrete sprayer, a matched slurry agitator and a slurry pump are arranged on the car body; an outlet of the concrete sprayer and an outlet of the slurry pump are connected with a spray head for a guniting machine; the front end of the spray head for the guniting machine is connected with a spray gun; and a powdery quick-setting agent adding device is connected with the concrete sprayer. Compared with the prior art, products of the concrete sprayer and the slurry agitator are conveyed to the spray head, and equipment is placed on the car body, so that the device has the advantages of good transportation effect, uniformity in guniting, low resilience ratio, and the like.

Description

technical field [0001] The invention relates to a motorized shotcrete device used for roadway support in coal mines, mines, water conservancy, tunnels and the like. Background technique [0002] At present, the shotcrete machine used in coal mines is generally shotcrete (mixture of cement, stone, sand, powder quick-setting agent) after being manually mixed and directly added to the feeding port of the shotcrete machine, so that not only the dust in the roadway is Due to the large quantity, the labor intensity of the workers is high. At the same time, because the material is mixed manually, the composition of the spray material is not uniform. The uniformity of the material sprayed from the spray gun of the shotcrete machine is very poor, and the rebound rate is very high, which directly affects the support of the large roadway. the quality of. [0003] At the same time, the existing shotcrete device is simply placed in the working area. With the spraying operation, the spra...
