Description :

　　Production of slope support hoisting type spraying machine and precise slope support spraying unit

　　The lifting and spraying machine improves work efficiency, without stopping the machine, and can work continuously. The hopper automatically loads materials, saving manual labor. The size of the machine can be selected according to the construction environment to facilitate construction and increase workload. In terms of machine operation, it is also very user-friendly. The machine can start working as soon as it arrives, and everyone can operate it.

　　preparation

　　① Check if the installation of anchor rods meets the design requirements and promptly address any issues found.

　　② Clean up the debris and debris at the spraying site, install the spraying machine in a stable and safe location on the top of the surrounding rock, with a distance of no less than 0.5m from the track. Connect the air and water pipelines, and ensure that the feeding pipeline is straight without sharp bends. The joints should be tight and not leak air. It is strictly prohibited to use non anti-static plastic pipes as feeding pipes.

　　③ Check if the spraying machine is in good condition, and conduct a no-load test run with power on. Tighten the friction plate and ensure that there is no air leakage.

　　④ Before spraying, high-pressure air must be used to flush the rock surface, and spray thickness signs should be installed on the tunnel arch and two sides.

　　⑤ Spray personnel should wear complete and effective labor protection equipment. Slope support hoisting type spraying machine and precise slope support spraying unit should be used for production.

　　The main features and advantages of the concrete dry spraying machine are: a direct rotor type dry bonding material chamber, smooth discharge, high efficiency and time saving; four point elastic compensation compression, good sealing effect of the concrete dry spraying machine, less dust near the machine, long service life of vulnerable parts; the mining explosion-proof spraying machine adopts low-pressure high-speed vortex airflow transportation to overcome problems such as bonding, pipe blockage and pulse separation during material transportation, uniform material flow, continuous and stable concrete dry spraying machine; a new type of nozzle and discharge elbow device improve the spraying effect, with less rebound and high spraying layer quality. The wet mixing method of concrete dry spraying machine is to send the mixed concrete to the nozzle through a grouting pump, and then spray it with compressed air. The concrete dry spraying machine adopts the working principle of low-pressure low-speed vortex airflow transportation and close range spraying, which overcomes problems such as pipe blockage, pulse, and segregation, making the sprayed material flow uniform and stable. Wet shotcrete machine is a device used for wet shotcrete. The concrete dry shotcrete machine has significant advantages such as low operating dust, low spray rebound, protecting the working environment, saving raw materials, and improving the quality of the sprayed layer. Moreover, it is easy to operate and maintain, and the slope support hoisting type shotcrete machine is used for the production of precise slope support shotcrete units.
