Gob - Clean feeding material train on the train for Gob clean by Professor Wai Hing Xi'an University of Science and Technology to optimize an outfit invention (patent ZL201320722526.1) According to a recent pumping system. The system integrates bottom-dump haul trucks and dust enclosed continuous feeding machine combination. The system can transport unloading continuous seamless connectivity, now the technology is exclusive. Technical Background: Currently, coal mining face and fill mining for Gob - pouring concrete wall construction of the sand, gravel, concrete and other mixed materials needed, after the past through artificial ground spices bagging, loading, Face to mine again on artificial unloading material handling to complete, the labor intensity of such workers is too large, back and forth movement of materials cost a lot of man-hours, and the high rate of breakage caused by bagging a lot of waste material; on the existing use of mechanical transport feeding device is equipped with various functions performed by each, the equipment is poor and can not work one move, bring a lot of inconvenience to the construction and construction efficiency is relatively low. Trains on the introduction of clean material: Gob - Clean feeding trains, mobile transport feeding system including loading and unloading equipment, feeding device for continuous feeding machine, unloading device for automatic unloading truck group, The system also includes a control device, the control device by lifting chain hook and chain with three consecutive feeder, automatic unloading trucks set of links on the mobile transport feeding system, adapted to the mine stope and fill mining Roadway along to stay pouring concrete roadway construction of the wall material, especially for steeply inclined broken roof seam Gob - pouring concrete wall material, the use of the utility model to replace the manual handling of machinery, improve work efficiency. Train patents on clean feed items: 1. material unloading train transport integrally formed integrated, seamless joint operation. 2. Transport equipment clusters connected and can run independently from the train. 3. Dynamic unified under the home, compact short-circuit connection, to achieve high reliability. 4. haul truck and the feeder seamless dosing devices. 5. feeder feeding boom turning adjustable feed section may turn connected to a specially designed lift. Clean feeding Train Features: 1. Avoid positioning move to help break at the end of roadway expansion ferret Sump pumps and other ancillary works and add equipment. 2. Trains haul feed to achieve a seamless convergence, to avoid dust lifted, can reduce dust 80%; 3. Closed haul hopper cars arranged in groups, transport dry spices meet once a day dosage, no waste material; 4. Haul truck and feeder connections formed by suspension trains, mobile anytime, reduced equipment tubing lengths to avoid blocking the tube and ready to meet the Face stoping mining movement; 5. Material transport train on the mobile unit comes with power, moving along the track in place without special equipment installation of chamber and immediately put into operation, there is no equipment assembly processes. Clean feeding trains advantages: 1. High degree of mechanization, high reliability operation; 2. Without any ancillary works, greatly reducing labor; 3. Seamless connectivity, reduce dust 80%; flexible assembly integration, move with the mining face at any time
