Construction Engineering Slope Support Concrete Shotcrete Pump
Description of Dry Sprayer Shotcrete Grouting Machine
The machine is mainly driven by a motor, reducer, rotor assembly, sealing plate, rubber plate, compactor mechanism, hopper seat, mine wheel, vibration hopper, a compression mechanism, air Systems and electronic control devices, and other components. The motor shaft ends the drive gear shaft and, after decelerating by the gear unit, drives the rotor mounted on the output shaft to rotate.

Advantages of Dry Sprayer Shotcrete Grouting Machine
Shotcrete machine is a new type of high-efficiency shotcrete machine with reasonable structure, humanized design, reliable performance, convenient operation and maintenance, and long service life. Dust-free, low noise, and low rebound rate when working. The machine greatly reduces the dust concentration beside the machine and the nozzle improves the working environment of workers and reduces the pneumoconiosis caused by excessive dust. The device has obtained three national patents.
As a tide-type shotcrete machine, construction spraying is suitable for railway (highway) tunnels, high-rise buildings, and diversion culvert projects. The machine has a simple structure and is easy to operate and maintain. Unique pressing device.
Features of Dry Sprayer Shotcrete Grouting Machine
The shotcrete machine is mainly composed of the rotor-type concrete sprayer, cement slurry mixer, extrusion cement slurry pump, electrical control box, discharge elbow, air system, mixing device, spray gun, frame, and other parts.
1. Jet machine: It is mainly composed of a hopper, stirring device, discharge elbow, air system, rotor, reducer, and other parts. The motor drives the rotor to rotate through the reducer. Load the mixed material into the rotor, and send it out of the discharge elbow by the air pipeline in the air system, and then the assistant of the auxiliary air inlet pipeline in the air system sends the mixed material through the conveying pipe, Nozzle, spray to the spray surface.
2. Cement slurry mixer: It is mainly composed of the electric motor, gearbox, water tank, upper mixing barrel, lower mixing barrel, water tank control valve, and feeding valve of the upper mixing barrel. This cement slurry mixer is a double-barrel type. Stir one barrel in the upper bucket first, then put it into the lower bucket for preparation, and after the upper bucket and stir another bucket, then start the mud pump, so that it can work continuously.
3. Extrusion cement slurry pump: It is mainly composed of a motor, gearbox, pump casing, eccentric wheel frame, rubber hose, pipe joint, etc. The pump is a positive displacement pump, which does not require irrigation and drainage, and has the strong self-priming ability.
4. Mixing device: This mixing device is composed of left and right spiral stirring assembly and mud input device. Connected to the screw stirring assembly are the delivery pipe and the spray gun.
