The main pretext chain conveyor wheels, tail wheel, conveyor chains, chassis and drive components. Regular intervals welded symmetrical L-shaped bar on the conveyor to drive materials. When the chain conveyor work, the lower part of the chain of slot machine moves forward, so that the material inside the slot machines increased pressure within the friction between the material particles increases, when the internal friction of the material is greater than the material and machine slot wall When external friction, materials will move forward together with the conveyor for continuous whole movement. Transporting material in the machine slot high efficiency chain conveyor was overall liquidity, and thus a smaller slot machine space can transport large amounts of materials, equipment dimensions are correspondingly smaller. With low energy consumption within the aircraft friction materials conveyed, friction-free movement of the conveyor chain and the chassis. Under the same conditions of transport capacity and longer transport distances, the aircraft's power consumption is about 40% lower than the screw conveyor. Roller conveyor failure rate on the rail rolling conveyor with the cabinet without friction. Chain made of alloy steel heat treatment process, the normal life of about three years, running low failure rate. In addition to the head and tail bearing, the conveyor without lubrication points. I first company in quality, reasonable price, abide by the contract, technical advice, * principle checked and dedication to customer service.
