Shotcrete tanker

Abstract

The invention discloses a concrete spraying tank truck. The concrete spraying tank truck comprises a truck body, wherein a tank is arranged on the truck body, a stock bin is arranged in the tank, a feed inlet is formed in the top of the tank, a spiral feeder is arranged on the bottom of the tank, a first discharge outlet is formed in the portion, close to the tail of the tank, of the spiral feeder and is connected with a wind and material mixer, and the wind and material mixer is connected with a spray gun; a front-end receiving port and a rear-end receiving port are formed in the upper portion of the spiral feeder, both the front-end receiving port and the rear-end receiving port are located in the stock bin of the tank, receiving port sliding cover plates are arranged on the front-end receiving port and the rear-end receiving port respectively in a sliding mode, and the two receiving port sliding cover plates are driven by corresponding cover plate cylinders respectively to slide. The concrete spraying tank truck has the advantages that the stock bin, the spiral feeder, the wind and material mixer and the spray gun are integrated, full mechanization of the shotcreting technology including material preparation, blending, transportation, feeding and delivery is achieved, the working intensity of operating staff is relieved greatly, and harm of flying dust to operating staff is avoided.

Description

technical field [0001] The invention relates to a shotcrete tank truck. Background technique [0002] In mine and tunnel construction, the application of shotcrete technology has been very common. At present, the construction equipment for shotcrete is rotor type concrete shotcrete machine. In many cases, this type of spraying machine is to transport the spraying raw materials to the construction site, after manual unloading, manual mixing, manual loading, and manual screening of large-sized sand and stones, it can enter the rotor type spraying machine. Shotcrete operation at the material receiving port. Its construction process is complicated, it produces a lot of dust, the degree of mechanization is not high, and there are serious problems such as large number of people and high labor intensity of operators. Although the current relatively advanced rotor-type concrete shotcrete machine has added auxiliary equipment such as loading and reloading, and strives to reduce th...

AI Technical Summary

Problems solved by technology

Its construction process is complicated, it produces a lot of dust, the degree of mechanization is not high, and there are serious problems such as large number of people and high labor intensity of operators.

Although the current relatively advanced rotor-type concrete shotcrete machine has added auxiliary equipment such as loading and reprinting, and strives to reduce the labor intensity of operators as much as possible, it still has not solved the problem of manual feeding and reprinting.

Each additional reprint will increase the dust-causing conditions

The rotor-type spraying machine is in a pulsed working state, and the spraying pipe is prone to fatigue damage under the pulse pressure; although it has been modified many times, the air return between the rotating disc and the fixed friction plate of the rotor-type spraying machine and the receiving port The dust problem always exists and is more serious, which is more harmful to the operators
