Abstract

The invention belongs to the technical field of concrete pulp shooting machines, and relates to a wet shotcreting machine. The wet shotcreting machine has two sets of independent power systems, that is, a fuel engine power system and a motor power system. The two sets of systems can realize free switchover through a power selector switch. A concrete pumping system comprises an accelerating agent container, an air compressor, a compressed air shunt, an accelerating agent mixer, a mixed flow nozzle, and a hopper. After the accelerating agent is mixed with compressed air, the accelerating agent is conveyed to the mixed flow nozzle, and meanwhile concrete in the hopper is pumped to the mixed flow nozzle through a concrete pump. After the compressed air, the accelerating agent, and the concreteare mixed in the mixed flow nozzle, the mixture is sprayed to a construction working plane through a guniting pipe, the concrete is uniform insetting and pouring quality is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of concrete spraying machines, and relates to a wet concrete spraying machine. Background technique

[0002] The main feature of the concrete wet shotcrete machine currently on the market is the automobile chassis, and the concrete pumping mechanism is added on the basis of this chassis, and the single nozzle or double nozzle operation is used at the same time; its products are mainly added on the basis of the concrete vehicle pump. Mortar nozzle and accelerator delivery system.

[0003] Disadvantages of existing products: the walking system is a car chassis, which uses a single power system. When the power system fails, the whole machine will completely collapse and cannot work, and the car chassis cannot better adapt to complex terrain conditions, and Construction requirements in tight spaces, such as tunnel interior construction. At the same time, the injection system cannot intelligently mix the concre...
