Description

Technical Field

[0001] The utility model relates to a conveyor belt deviation adjusting roller device of a belt conveyor, belonging to the technical field of belt conveyor equipment. Background Art

[0002] Belt conveyors are widely used in industrial and mining enterprises, ports, construction sites and other places to transport various materials and products. When transporting coal, there are many types of coal, such as sticky coal, lump coal, and flour coal. These special types of coal cannot be completely dispersed when they fall on the conveyor belt of the belt conveyor. They will accumulate on one side of the conveyor belt and cause the conveyor belt to deviate. The conveyor belt deviation will cause the conveyor belt to rub against the steel structure of the equipment, causing damage to the conveyor belt itself and the equipment, and severe damage to the machine. At the same time, the damage of the conveyor belt will cause coal to spill onto the equipment and the ground, affecting the surrounding environment.

[0003] Deviation adjustment rollers are an important component of belt conveyors. Deviation adjustment rollers can adjust the conveyor belt to achieve a stable operating state for the conveyed materials, while avoiding damage to the conveyor belt. Traditional deviation adjustment rollers consist of a main roller and inclined rollers on both sides. The main roller and the inclined rollers on both sides cannot be adjusted in angle, so the angles on both sides of the conveyor belt cannot be adjusted. Since the inclined rollers on both sides of the conveyor belt cannot be corrected and adjusted, it is easy to cause inconsistent wear in the middle or on both sides of the conveyor belt, affecting the service life of the conveyor belt. At the same time, the deviation adjustment rollers currently used are fixed on the frame of the conveyor, without height adjustment and buffer structure. They cannot be adjusted in height or buffered during use, which also affects the convenience of use and the service life of the rollers, and increases the cost of use. Utility Model Content
