Description

Technical Field

[0001] The invention relates to the field of belt material conveying machinery, and in particular to a belt conveyor compacting and steering device. Background Art

[0002] Belt conveyor is a commonly used material conveying equipment, widely used in various industries such as metallurgy, mining, coal, ports, electricity, building materials, and chemicals. The belt conveyor adopts two methods to change the inclination angle: direct inclination change and gradual inclination change. Direct inclination change usually uses a single-axis belt pressure roller or multiple single-axis belt pressure rollers to compress the complete belt inclination change; the gradual angle change relies on the deadweight of the conveyor belt. By enlarging the angle diameter, the conveyor belt naturally hangs down on the lower roller, and the change of the conveying inclination of the conveyor belt can be completed without adding belt pressure rollers.

[0003] Since the gradual inclination of the conveyor needs to adopt a large radius to meet the natural drooping requirements of the conveyor belt, the gradual inclination conveyor is much longer than the direct variable angle conveyor. The greater the inclination change, the longer the conveyor is extended. Not only does it increase the cost of the conveyor equipment, but also because it occupies a large space, has a compact spatial structure, and is limited in length, the gradual inclination conveyor is mostly used in areas with loose spatial structures, while for belt conveyors with limited spatial structures, direct variable inclination conveying is mostly used.

[0004] The single-axis belt-pressing roller steering device is one of the important parts of the belt conveyor. Its main function is to prevent the conveyor belt from lifting off the roller surface at the turning part, that is, when the belt conveyor starts without load, the belt and the material are running, causing material spillage and complicated angle adjustment steps. The existing single-axis belt-pressing roller devices at home and abroad are two pressure rollers connected to a horizontal axis, and the two rollers each press one belt edge of the belt to convey the material. This device has many disadvantages. First, when the conveyor belt conveys large pieces of material, it is easy to be blocked by the pressure roller shaft, so that the large pieces of material cannot pass through, resulting in material spillage; second, due to the extremely small contact surface between the belt-pressing roller and the conveyor belt, when the belt is tensioned, the tension on both sides of the belt is much greater than that on other parts, which can easily cause the outer edges of the conveyor belt to tear and shorten the service life of the conveyor belt; third, due to the friction between the belt-pressing roller and the conveyor belt, the edge of the conveyor belt is seriously worn, which will also shorten the service life of the conveyor belt and increase the operating cost of the conveyor.
