Description

Technical Field

[0001] The utility model relates to the field of mineral transportation, in particular to a working face chute belt conveyor with large vertical height and long transportation distance. Background Art

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries, such as assembly, testing, debugging, packaging and transportation of objects. They are economical logistics conveying equipment that is indispensable for rhythmic assembly lines. Belt conveyors can be divided into heavy-duty belt conveyors such as mining belt conveyors and light-duty belt conveyors such as those used in electronic plastics, food and light industry, chemical and pharmaceutical industries according to their conveying capacity. Belt conveyors have strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can easily implement programmed control and automatic operation. They use continuous or intermittent movement of the conveyor belt to convey powdered or granular objects. They run at high speed, smoothly, with low noise, and can be conveyed up and down slopes.

[0003] When an existing belt conveyor is working in a mining area, after the ore at one end is transported, the conveyor belt will rotate to the other side. At this time, the particles on the belt will fall into the shell due to gravity. Subsequently, when the belt rotates for transportation, the mineral particles will continue to wear the outer end surface of the belt. In addition, most of the belt conveyors used in the mining area have a long conveying stroke. When conveying too heavy materials on the belt, the driving force of the drive motor is insufficient and it is easy for the belt to run away, which is more dangerous.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0039] When the material on the conveyor belt 14 is too heavy and the stepper motor 15 cannot drive the conveyor belt 14, the conveyor belt 14 slides in the opposite direction under the action of the material thereon. At this time, the pawl 34 presses against the ratchet wheel 33, causing the friction roller 31 to stop rotating. The friction roller 31 drives the sixth roller 32 to stop rotating through the first spur gear 36 and the second spur gear 37, so that the friction roller 31 and the sixth roller 32 fix the conveyor belt 14 to prevent it from running away.
