Embodiment 1

[0039] The concrete structure of a long-distance dust-free concrete spraying machine comprises a machine body 1, a feeding mechanism 2, a spraying mechanism 3 and a driving mechanism 4. The feeding mechanism 2 improves the feeding mode of the existing concrete spraying machine, and the spraying mechanism 3 increases the spraying distance by swirling feeding; The feeding mechanism 2 and the spraying mechanism 3 are arranged up and down, so that the concrete can be fed conveniently, and the structure is compact. The sealing compensation method is adopted to realize the high-strength sealing in the shotcreting process, so that the air supply pressure is increased, the conveying distance of concrete is increased, and the dust pollution caused by insufficient sealing is reduced.

[0040] The machine body 1 includes wheels 11, a frame 12 and a chassis 13. The wheels 11 are arranged at the lower part of the chassis 13, and the frame 12 is arranged above the chassis 13. The feeding mechan...

Embodiment 2

[0044] On the basis of Embodiment 1, this embodiment further improves the feeding mechanism of concrete shotcrete machine, thus improving the sealing performance of the feeding mechanism and simplifying the manufacturing process of the feeding mechanism of concrete shotcrete machine.

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

Abstract

A long-distance dust-free shotcrete machine, relating to the technical field of concrete spraying equipment, and comprising a machine body (1), a feeding mechanism (2), a spraying mechanism (3) and a driving mechanism (4). The machine body comprises wheels (11) and a chassis (13); the feeding mechanism comprises a hopper (21), a feeding shell (22) and a feeding shaft (23), the hopper being connected to the feeding shell, the feeding shaft being provided in the feeding shell, a pressure relief port (24) being provided on the feeding shell, and a plurality of feeding bins (27) being provided on the feeding shaft in a centrally symmetrical manner; the spraying mechanism comprises a feeding auger (31), a feeding box (32) and a swirl injector (33), the feeding auger being provided inside the feeding box, and the swirl injector being connected to the feeding box; and the driving mechanism comprises a motor (41), a speed reducer (42) and a gear box (43), the motor being connected to the speed reducer, the speed reducer being connected to a gear in the gear box, and the driving mechanism driving the feeding shaft and the feeding auger to rotate. The long-distance dust-free shotcrete machine solves the technical problems of the pressure for transporting concrete for a long distance being insufficient and dust being easily generated at the hopper, and also has advantages such as compact structure and good sealing effect.

Description

Technical field [0001] The invention relates to the technical field of concrete shotcrete equipment, in particular to a dust-free concrete sprayer for long-distance transportation. technical background [0002] Concrete shotcrete machine is an indispensable equipment in the construction of coal mine roadway, railway and highway tunnel. At present, the common concrete shotcrete machines mainly include rotor concrete shotcrete machine, rotor piston concrete shotcrete machine and plunger concrete shotcrete machine. However, the conveying distance between the rotor-type concrete jet and the rotor-type concrete jet is close, the amount of dust is large, the machine is frequently moved, the labor intensity is high, and the shotcreting efficiency is low; Plunger concrete sprayer is mainly used for wet spraying process, which is complicated in process, large in design and troublesome to clean and maintain. Therefore, it is necessary to provide a concrete sprayer with small volume, small ...
