Description

Technical Field

[0001] The utility model relates to a conveying device, in particular to a belt conveyor. Background Art

[0002] Belt conveyor is a kind of equipment that uses conveyor belt to carry materials and uses the friction between conveyor belt and materials to drive materials from material input end to material output end. It is widely used and can transport both bulk materials and finished items. Belt conveyor is usually composed of conveyor frame, rollers rotatably supported at both ends of conveyor frame and annular conveyor belt tightly sleeved on two rollers. Upper and lower rollers for supporting conveyor belt are respectively provided below the upper and lower sides of conveyor belt. When belt conveyor is used to transport bulk materials, its upper rollers are mostly grooved upper rollers, so that the conveyor belt is in the shape of a groove with low middle and high sides. Conventional grooved upper rollers include a bottom roller and side rollers located at both ends of the bottom roller obliquely upward. After adopting grooved upper rollers, the bulk materials being transported can reduce scattering in the middle, but its discharge position can only be at the end of conveyor belt. Since the frame length of belt conveyor is fixed, belt conveyor cannot be used when materials need to be discharged at different positions. Utility Model Content
