Description

Technical Field

[0001] The utility model relates to the technical field of electric rollers, in particular to a belt electric roller. Background Art

[0002] When screening mineral materials, a drum is needed. Whether it is powder screening with various screens or magnetic separation, a drum device is often used. The more common connection method is to drive it to rotate through a belt motor. The acquisition of electric energy is relatively simple, and the motor is relatively quiet. The speed is also easy to control, so it is often used to drive various drum equipment.

[0003] When in use, the motor drives the drum to rotate through the belt, and the belt has a certain degree of elasticity and will be worn to a certain extent during long-term use. Therefore, whether the belt is too long or worn, it will cause the belt to loosen, thereby affecting the transmission. A transmission structure that can be easily adjusted is required. In addition, during use, there is contact between the drum and the mineral and long-term rotation and wear of the drum itself, so replacement or maintenance is often required, and a structure that can be easily replaced and repaired is required.
