Abstract

The invention discloses a wet-injection double-barrelled injection machine, relating to the technical field of coal mine tunnelling and guniting. The injection machine is provided with a base and a stirring box arranged on the base, and a hopper is arranged at an opening of the stirring box; the hopper is internally provided with a movable baffle, and the outer case of the hopper is provided withmultiple water inlet holes; two stirring devices are symmetrically arranged in the stirring box, a baffle is arranged between two stirring teeth, and the baffle separates the two stirring devices; a reduction box and a power plant are arranged at the two ends of the stirring box; feed openings are arranged at the bottom of the two sides of the stirring box, each feed opening is connected with onematerial cylinder, each material cylinder is connected with a discharging hole by virtue of a pipeline; and the injection machine also comprises a hydraulic system which is used for controlling opening and closing of the material cylinders. The wet-injection double-barrelled injection machine disclosed by the invention has the advantages that: personal health and personal safety can be avoided from being harmed by dust pollution, and the working efficiency is high.

Description

Technical field [0001] The invention relates to the technical field of shotcreting for tunneling in coal mines, in particular to a wet spraying double-pipe jet; it is mainly used for shotcreting support for tunnels in coal mines. Background technique [0002] Jet machine is an indispensable equipment for coal mining. The equipment has the advantages of low cost, light weight, easy realization, and great power for remote control of pressure transmission. Jet machines are not only widely used in large-scale projects such as coal mine excavation and support, surface water, electricity, construction, etc., but also in all industries such as industry, agriculture, underground mining, military, etc., mixing soil; with the continuous development of technology The application is also more and more extensive. Mixed soil is a kind of fluid that mixes cement, sand, stones, and water through a jet machine. The purpose of all fluids is to temporarily support the roof of construction and coa...
