The belt climbing conveyor used for filling is a special continuous conveying equipment, and its mechanical structure mainly includes the following key parts: 
1、 Main Composition Structure 
Conveyor belt: The conveyor belt is the core component of a belt conveyor, serving as both a load-bearing and traction component. It forms an annular belt around the transmission drum and the tail drum, and is driven by friction to transport materials. In the climbing section, the conveyor belt needs to have sufficient strength and wear resistance to ensure stable material transportation in the vertical or inclined direction. 
Drive device: The drive device usually consists of a motor, a reducer, and a transmission drum. The motor provides power, the reducer reduces speed and increases torque, and the drive drum drives the conveyor belt through friction. 
Drum: The drum includes a transmission drum and a reversing drum. The transmission drum directly drives the conveyor belt, while the reversing drum is used to change the direction of the conveyor belt. In a climbing belt conveyor, the drive drum is usually located at the starting end of the conveyor, while the reversing drum may be distributed at different positions of the conveyor to achieve material turning and climbing. 
Roller and bracket: Roller is used to support the conveyor belt, reduce its movement resistance, and ensure its smooth operation. The bracket is used to fix the rollers and other components of the conveyor. During the climbing phase, the rollers may require special design to accommodate the tension and guidance requirements of the conveyor belt. 
Tightening device: The tensioning device is used to apply initial tension to the conveyor belt, ensuring that it does not slip on the drive drum and maintains sufficient frictional driving force. In a climbing belt conveyor, the tensioning device may need to be adjusted according to the climbing angle and material weight. 
Cleaning device: The cleaning device is used to remove residual materials on the conveyor belt, preventing them from affecting the normal operation of the conveyor. In the climbing belt conveyor, special attention should be paid to the setting of the cleaning device to ensure that materials do not accumulate on the conveyor belt and affect the conveying effect. 
Loading and unloading device: The loading device is used to load materials onto the conveyor belt, while the unloading device is used to unload materials at the end or middle position of the conveyor belt. During the filling process, the unloading device may need to be connected to the filling equipment to achieve accurate material transportation and filling. 
2、 Special Structure and Design 
Design of climbing section: The climbing section of a climbing belt conveyor usually uses specially designed devices for tensioning and guiding to ensure that the material can climb smoothly. These devices may include inclined rollers, specially shaped rollers, or guide plates. 
Safety protection device: As climbing belt conveyors are usually used for vertical or inclined material transportation, their safety protection devices are particularly important. These devices may include backstops (used to prevent the equipment from reversing due to the weight of the load after shutdown), emergency stop buttons, overload protection devices, etc. 
3、 Working principle 
The working principle of a belt climbing conveyor is based on the frictional force between the conveyor belt and the drum. When working, the driving device drives the transmission drum to rotate and drives the conveyor belt to run through friction. After the material is loaded onto the conveyor belt, it moves together with the conveyor belt and is tensioned and guided by a specially designed device during the climbing section, ultimately achieving continuous conveying and filling of the material. 
In summary, the mechanical structure of the belt climbing conveyor used for filling is complex and refined, including multiple key components and special designs. These components and designs together ensure stable conveying and efficient filling of the conveyor in vertical or inclined directions.
