Which tunnel mucking machine is good? Xiangyang wheeled tunnel mucking machine, mine tunnel mucking machine is suitable for mine excavation, tunnel engineering, water conservancy and hydropower tunnel operations. It has mobility, flexibility and safety. Greatly reduce labor intensity and improve production efficiency. Tunnel mucking machine generally consists of working system, chassis system, hydraulic system and electrical system. Its hydraulic system is mainly composed of oil cylinder, oil pump, multi-way valve and hydraulic pipeline.
Multi-way valve, full name of multi-way reversing valve, is mainly used to control the oil cylinder, motor to complete forward, backward, excavation, loading, folding of the conveyor and so on by operating the handle forward or pulling back.
The multi-way valve of Zhongliang tire-type tunnel mucking machine is divided into six-port valve (for non-folding vehicles) and seven-port valve (for folding vehicles).
Each main valve block of the multi-way valve controls the forearm, swing, motor, folding, lifting, bucket, boom, and safety valve block from left to right. The first seven blocks, as their names suggest, complete the corresponding actions. The final safety valve block controls the pressure of the multi-way valve by adjusting the safety valve. Make the working pressure of the tunnel mucking machine within the standard range, and ensure that the corresponding work is completed.
