Description

Technical Field

[0001] The utility model relates to the technical field of lifting conveyors, in particular to a lifting conveyor for transporting materials in coal mines. Background Art

[0002] Belt conveyors for coal mines mainly refer to belt conveyors used in coal mining, production, transportation and processing. They have the characteristics of large transportation volume, complex working environment, strong carrying capacity and long transportation distance. Due to the variability of the environment in coal mines, the feeding height of the conveyor needs to be adjusted.

[0003] A Chinese utility model with publication number CN218490706U discloses a material transport lifting conveyor for coal mines. It can be adjusted in height and is suitable for adjusting the size in a narrow space. The wheels are convenient for workers to carry, and the adjustable legs are convenient for adjusting the height. The gravity of the whole machine is on the legs, making the equipment more stable. The device has a simple structure, and the components are easy to replace, and the operation and maintenance costs are very low; it is safe and reliable.

[0004] The device uses the cooperation of the lifting nut and the lifting seat to complete the lifting and adjustment of the conveyor frame. Due to the weight of the conveyor frame, the lifting nut needs to rely on a large rotational driving force when rotating, which increases the difficulty of adjustment for workers. In addition, before the four lifting nuts are adjusted, the conveyor frame will tilt. It is not only difficult to ensure that the four lifting nuts are in the same position, but the tilted conveyor frame also increases the difficulty of adjusting the lifting nuts. To this end, we provide a coal mine material transportation lifting conveyor to solve the above problems. Utility Model Content
