Wet mixing concrete spraying unit

Abstract

The invention provides a wet mixing concrete spraying unit. The wet mixing concrete spraying unit comprises a vehicle body, wherein the vehicle body comprises a bottom plate and rollers arranged at the bottom of the bottom plate. A water tank is arranged on the surface of the bottom plate, the water tank is of a hollow structure, a hydraulic sensor is arranged at the inner side of the bottom of the water tank, a water inlet pipe is arranged at the front face of the water tank, a water outlet is formed in one side face of the water tank, and a water pump is arranged on one side of the water tank. Firstly, cement aggregate are mixed with water, and then the mixture is transmitted to a mixing box for temporary storage through spiral conveying blades, dry materials such as sand and gravel arealso put into the mixing box after being crushed by a crushing roller, then wet cement and crushed sand dry materials are stirred and mixed, pressurized by an air compressor and sprayed onto the construction surface by an ejector so that the materials can be fully stirred and mixed, the uniform mixing state is achieved, the operation effect is improved, the amount of dust generated in the processis greatly reduced, and the health of an operation personnel is ensured.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to a wet mixing concrete injection unit. Background technique [0002] Concrete spraying machine is equipment for concrete spraying in mine roadways, tunnels, national defense caves, mountain slope protection and other places. It mainly uses compressed air to continuously transport concrete through the material cavity and along the conveying pipeline, and spray it onto the construction surface. At present, concrete spraying machines at home and abroad are divided into dry spraying machines and wet spraying machines. Dry spraying machines send powdery materials into the spraying machine. There are multiple material cups in the spraying machine. Next, spray it from the material cup into the discharge elbow, enter the delivery pipe, and add water to the nozzle of the delivery pipe to mix the material and water. The disadvantage of the dry spray machine is tha...

AI Technical Summary

Problems solved by technology

Although the above-mentioned wet spraying machine is equipped with a hopper, when the material enters the hopper, the mixing of the material is completed in the screw agitating conveying system, and the screw agitating conveying system is a device that transfers the material from the hopper to the spraying mechanism, so The mixing and stirring time of the material is very short, that is, the material cannot be mixed and stirred in the form of storage, and is transported to the injection mechanism during the stirring process, resulting in insufficient stirring and mixing of the material, and the state of uniform mixing cannot be achieved. After spraying onto the construction surface, its quality cannot be guaranteed, which will affect the operation effect
