3. The scraper is a new technological substitute which replaces labor and intermittent machines in underground tunneling, excavation, and shipment. It guarantees the security and fast-speed of underground construction.
4.The scraper is belong to construction machinery, hole-mining equipment, underground excavation equipment, tunnel construction equipment, railway tunnel construction equipment, road tunnel construction equipment, power plant water diversion tunnel construction equipment, mining equipment, mining tunnel excavation equipment, diversion tunnel equipment in water conservancy project, culvert excavation equipment, coal mine roadway tunneling equipment, metal excavation equipment , iron ore excavation equipment, phosphate rock conveying equipment, manganese ore mining equipment, tunnel construction conveying equipment, excavation equipment, conveying equipment, loading and unloading equipment, construction equipment, mining equipment, conveying equipment, conveying machinery, complex excavation equipment, earthwork machinery,concrete machinery, underground tunneling equipment, road construction machinery, transshipment equipment, tunneling machinery, material handling machinery, coal mine explosion-proof equipment.It uses in a wide range, especially suitable for narrow space operating.
5. The features of scrapers include hydraulic walk, mining collection, transportation, loading, and clearing bottom.
6.The hydraulic walk of scraper is achieved by a hydraulic motor, reduction box, drive shaft, reduction box, and then drives the wheels. The hydraulic motor has three functions of forward, backward, and automatic brake. Mining collection is achieved by the four hydraulically operating shafts controlling the mechanical hand which have the function of mining, outriggers, loading, unloading, and the big arm can go up, down, left and right rotation. The function of transportation is achieved by a electric roller combined with conveyer belt and passive roller. The loading function is achieved by two hydraulic cylinder jack lifting conveyor frame to the loading or unloading height, and hydraulic lock locking cylinder as a fulcrum.
