Introduction to Type 1 Shotcrete Machine
Type 1 Shotcrete Machine is a new type of high-efficiency wet shotcrete construction equipment. It has the characteristics of high efficiency, high performance, stability, easy operation and maintenance, and strong adaptability to the working site. The shotcrete machine is mainly composed of a drive motor, a reducer, a rubber elbow rotor body assembly, a rubber wheel, a sealing plate, a hopper seat, a vibrating hopper pressing mechanism, an accelerating agent delivery system, an air duct system, an electronic control device and other components

Characteristics of the three-type shotcrete machine
The three-type shotcrete machine adopts a universal wheel structure, making it more convenient to move .
The straight-through rotor-type non-adhesive material chamber ensures smooth material discharging and is efficient and time-saving.
Four-point elastic compensation compression, good sealing effect, less dust around the machine, and long life of wearing parts.
Using low-pressure and high-speed vortex airflow for transportation, it overcomes problems such as sticking, pipe blocking, pulse separation and folding during material transportation, and the material flow is uniform, continuous and stable.
The nozzle adopts a discharge elbow device to improve the spraying effect, with less rebound and high spray layer quality.
Using high-quality wear-resistant lining plates and high-quality rubber plates, the service life is greatly improved.

Usage instructions and operating steps of the shotcrete machine
Precautions for the use of the shotcrete machine
The use instructions of the shotcrete machine and the working principle of the shotcrete machine , the troubleshooting and troubleshooting of the shotcrete machine are very detailed. It is recommended that you read the instruction manual of the shotcrete machine before use, add oil, and it will work normally after the connection is completed.
A special reminder is that the pressing mechanism of the shotcrete machine must be tightened after the shotcrete motor is started. Do not tighten it first and then start the shotcrete motor. Otherwise, the starting current will be too large. Damage the motor and cause unnecessary losses to you.
The operator must read the instruction manual carefully and be familiar with the machine structure and operating procedures before starting work.
Preparation before starting the machine: Check whether the connecting parts of the whole machine are firm and whether the rotating and sliding parts are flexible and reliable. Observe the cursor and check whether the lubricating oil in the reduction box is sufficient. The drive motor is connected to the power supply. When the inching motor is turned, the rotation direction should be consistent with the direction of the arrow. Otherwise, the phase of the power supply should be adjusted. The water supply stop valve of the vibrator air path nozzle on the main air path and the lower air path is placed in the closed state, and the main air pipe is connected to the air source. The water supply pipeline is connected to the water source, and the feeding pipe is connected to the host machine. Adjust the compression mechanism, first manually pre-press, then use a wrench to tighten and bend the feeding pipe, open the gas line stop valve on the main gas line, and observe that the pressure gauge is in the right direction. There should be no gas overflow from the rubber bonding plate.
In the spraying operation, first open the main gas line and lower gas line stop valve, open the nozzle water supply stop valve, and pre-wet the rock mass surface, then start the motor, open the vibrator gas line stop valve, and add the mixture to the hopper. Start spraying operation. During work, the nozzle operator should appropriately adjust the water supply of the nozzle to ensure that the concrete has a suitable water-cement ratio. The host operator should pay attention to the remaining air holes on the side of the host. If there is any remaining material discharged, the air supply volume of the lower air path should be appropriately reduced. Until there is no material discharged from the residual air port of the machine and the equipment works normally.
Before stopping the operation, first stop feeding. When no material is sprayed out from the nozzle, close the water supply stop valve, and at the same time add a small amount of wet sand and gravel into the hopper, and flush the remaining materials in the hopper and rotor cavity several times. When the nozzle is clean and no material is ejected from the nozzle, turn off the motor power and the gas line stop valves.
Type 5 shotcrete machine uses
Type 5 shotcrete machine is widely used in engineering construction, mine tunnels, culverts, subway, hydropower projects, underground engineering and coal high swamp mine tunnel shotcrete construction operations in various types of industrial furnaces and furnace linings. Refractory materials are used for spray molding or repairing various slope protection and greening construction, soil transportation and spraying. This machine can be used for tide spraying, dry spraying and individual fiber spraying operations.
