Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to an automatic hydraulic deviation adjuster without a power source. Background Art

[0002] As an important conveying equipment, belt conveyor is widely used in the bulk material transfer industry. However, due to factors such as manufacturing, installation and improper conveyor belt joints, most conveyors have the problem of conveyor belt deviation, and conveyor belt deviation has even become the main factor affecting the smooth operation of belt conveyors. The general principle of belt conveyor deviation adjustment is that when the conveyor belt deviates, the deviation adjustment device is driven to deflect, thereby generating a friction force that causes the conveyor belt to return to a balanced position, thereby achieving the purpose of conveyor belt deviation correction.

[0003] The existing non-powered automatic deviation adjuster does not require an external power source or other energy source, and can adjust the conveyor belt through its own structure. However, because there is no power source, it cannot alarm when the conveyor belt deviates.

[0004] Therefore, we propose a power-free automatic hydraulic deviation adjuster. Utility Model Content
