摘要：Tube chain conveyor is a new type of energy saving and high efficient continuous conveying equipment with flexible traction components. Due to the lack of theory research, in the domestic TCC compared with the foreign one there are some shortcomings including high energy consumption, small size, small applicable scope, etc. According to the limit equilibrium conditions of bulk material, we will research the scraper's static force acts on the material and the force's transmission area of scraper to get the tube chain conveyor scraper pitch's limit calculation formula. It is of great significance to promote the development of domestic tube chain conveyor.
