Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to a quick-detachable intermediate structure. Background Art

[0002] Belt conveyor is the abbreviation of belt conveyor, which is available in fixed and mobile types with simple structure and high efficiency. It is a continuous conveying machinery with flexible conveyor belt as material carrying and traction component. The legs and the middle frame are the middle body part of the belt conveyor. The belt conveyor with a longer body also takes a long time to install. Traditional legs and middle frames are connected by bolts, which takes a long time to install and is greatly affected by processing accuracy. Some ground belt conveyors are fixed by welding, which is difficult to disassemble and has great limitations. For this reason, we propose a quick-detachable middle structure. Utility Model Content
