Embodiment 1

[0039] A specific structure of a long-distance dust-free concrete sprayer includes a body 1 , a feeding mechanism 2 , a spraying mechanism 3 and a driving mechanism 4 . The feeding mechanism 2 improves the feeding method of the existing concrete spraying machine, and the spraying mechanism 3 increases the spraying distance by means of swirl feeding; the feeding mechanism 2 and the spraying mechanism 3 are arranged up and down, so as to facilitate concrete feeding, and the structure is compact. The compensation method realizes the high-strength sealing of the spraying process, thereby increasing the air supply pressure, increasing the conveying distance of concrete, and reducing the dust pollution caused by insufficient sealing.

[0040] The fuselage 1 includes wheels 11 , a vehicle frame 12 and a chassis 13 , the wheels 11 are arranged at the bottom of the chassis 13 , and the vehicle frame 12 is arranged at the top of the chassis 13 . The feeding mechanism 2 includes a hopper...

Embodiment 2

[0044] On the basis of Example 1, this embodiment further improves the feeding mechanism of the concrete sprayer, thereby improving the sealing performance of the feeding mechanism and simplifying the manufacturing process of the feeding mechanism of the concrete sprayer.

[0045] The specific structure of a conical long-distance dust-free concrete sprayer includes a body 1 , a feeding mechanism 2 , a spraying mechanism 3 and a driving mechanism 4 .

Abstract

The invention provides a long-distance dust-free shotcrete machine, and relates to the technical field of concrete spraying equipment. The long-distance dust-free shotcrete machine includes a machinebody, a feeding mechanism, a spraying mechanism and a driving mechanism, the machine body includes wheels and a chassis, the feeding mechanism includes a hopper, a feeding shell and a feeding shaft, the hopper is connected with the feeding shell, the feeding shaft is arranged in the feeding shell, a pressure relief port is formed in the feeding shell, a plurality of feeding cabins are arranged onthe feeding shaft in central symmetry, the spraying mechanism includes a feeding screw, a feeding box and a swirl injector, the feeding screw is arranged in the feeding box, the swirl injector is connected with the feeding box, the driving mechanism includes a motor, a reducer and a gearbox, the motor is connected with the reducer, the reducer is connected with a gear in the gearbox, and the driving mechanism drives the feeding shaft and the feeding screw to rotate. According to the long-distance dust-free shotcrete machine, the technical problems that the pressure of long-distance conveying of concrete is insufficient and dust is prone to being generated at the hopper are solved, and the advantages of compact structure and good sealing effect are further achieved.

Description

technical field [0001] The invention relates to the technical field of concrete spraying equipment, in particular to a dust-free concrete spraying machine for long-distance transportation. Background technique [0002] Concrete spraying machine is an indispensable equipment in the construction of coal mine roadway, railway and highway tunnel. At present, the common concrete spraying machines mainly include rotor concrete spraying machine, rotor piston type and plunger concrete spraying machine. However, the conveying distance of the rotor type concrete spraying machine and the rotor piston type concrete spraying machine is relatively short, the amount of dust is large, the machine is moved frequently, the labor intensity is high, and the spraying efficiency is low; the plunger type concrete spraying machine is mainly used for wet spraying process , the process is complicated, the design is large, and the cleaning and maintenance are troublesome. Therefore, it is necessary t...
