Description

Belt conveyor and elastic adjustable belt pressing carrier roller assembly for same Technical Field The utility model relates to a belt conveyor technical field especially relates to a belt conveyor presses belt idler subassembly and belt conveyor with adjustable elasticity. Background The belt conveyor is a main transportation device for conveying loose materials, and is widely applied to material transportation in underground mining such as coal mines and non-coal mines. Especially for metal mining, in recent years, an attempt has been made to adopt a comprehensive mechanical mining process, and a belt conveyor is applied to a metal mining comprehensive mining working face, so that the belt conveyor has great significance in reducing the abrasion of conveying equipment and prolonging the service life of the equipment. The belt pressing carrier roller is a main part of a belt conveyor and mainly used for changing the running direction and angle of a conveying belt or pressing the conveying belt to increase the surrounding angle of the conveying belt and a transmission roller. The service life of the belt pressing carrier roller seriously influences the normal operation and production application of the belt conveyor. As is well known, when an underground mining working surface is used as a first production site for mining mineral resources, the operating space is narrow, mechanical equipment is more, the visual environment is poor, and other adverse factors influencing the equipment maintenance are more, and once a belt pressing carrier roller fails, the normal operation of a belt conveyor is directly influenced, so that the shutdown of a mining production system is caused, and great loss is brought. The working face operating mode environment is complicated in the mine underground mining, and metal mine ore water content such as bauxite is great, and material viscidity is big, and the conveyer belt inevitable can bond the material when operation, and when the great particulate matter material that bonds on the conveyer belt passes through the area bearing roller, can cause to press belt bearing roller department conveyer belt tension sudden change, easily tears the conveyer belt or damages the area bearing roller. In addition, when the load of the belt conveyor changes suddenly, the tension at the belt pressing carrier roller is easy to change suddenly, and the belt pressing carrier roller is easy to damage.
