Mining concrete wet spraying machine

Abstract

The invention discloses a mining concrete wet spraying machine, and relates to the technical field of engineering machinery. The mining concrete wet spraying machine comprises a frame body, a power device and a concrete pumping system, wherein the concrete pumping system comprises a pumping device and an arm body telescopic device, the pumping device comprises a loading end and a first output end, a platform frame is suspended at the front end of a front frame and is used for mounting the arm body telescopic device, the concrete pumping system further comprises a gas compression device, the gas compression device is arranged on the front frame, the arm body telescopic device is arranged at the front end of the front frame and is close to the ground, so that the arm body telescopic device can rotate in the circumferential direction, and the rotation is not easy to interfere with other devices on the frame. The mining concrete wet spraying machine has the advantages of being stable in machine body structure, good in balance capacity, high in gas conveying efficiency, small in energy consumption, high in spray-seeding efficiency and the like.

Description

technical field [0001] The present disclosure relates to the technical field of engineering machinery, in particular to a mining concrete wet spraying machine. Background technique [0002] Concrete wet spraying machine is a kind of machine that uses hydraulic pressure to transport the ready-mixed concrete mixture to the spray gun through the pipeline, and connects compressed air and accelerator at the nozzle port to spray the mixture to the sprayed surface at high speed, and forms it through rapid solidification and hardening. Construction machinery for concrete support layers. Shotcrete technology is widely used in various construction fields because of its simple process and economical cost. [0003] The concrete wet spraying machine mainly drives the pumping device to spray concrete through the extension of the cantilever of the arm body telescopic device. In the non-working state, the cantilever is in the retracted state. In the two different states, the gravity effect...
