Description

Technical Field

[0001] The invention relates to the technical field of conveyors, in particular to a discharge device for an adjustable belt conveyor. Background Art

[0002] A belt conveyor is a general-purpose mechanical device that continuously transports bulk or pieced materials. It is widely used in industries such as mining, electricity, metallurgy, chemicals, and ports. Its core components include conveyor belts, drive units (motor, reducer, rollers), rollers, tensioning devices, and frames. As load-bearing and traction components, conveyor belts are usually made of rubber, PVC, or steel rope cores, and have high strength, wear resistance, and tear resistance. The drive unit provides power, and material transportation is achieved through the friction between the rollers and the conveyor belt; rollers support the conveyor belt to reduce operating resistance, and trough rollers can increase the conveying capacity. Belt conveyors have the characteristics of long conveying distances (up to several kilometers), large conveying capacities (thousands of tons per hour), low energy consumption, and smooth operation. They can be arranged horizontally, inclined, or in combination. Modern belt conveyors also integrate intelligent control systems to achieve speed regulation, fault monitoring, and energy-saving operation, making them key equipment for efficient and continuous conveying.

[0003] In daily operation of belt conveyor, due to the high belt speed, coal and gangue are easily dropped out of the belt by overlapping the unloading device along the direction of the upper belt coal flow, and accumulate under the unloading roller.

The second roller 711 is connected to the first roller 74 through a belt 75. By setting the second limiting ring 78, the rotating disk 79 can be limited so that the rotating disk 79 can rotate stably in the inner cavity of the second limiting ring 78, so that when the first roller 74 drives the belt 75 to rotate, the second roller 711 can be connected to the first roller 74.

The inner wall of the air cylinder 720 is fixedly connected to the stirring plate 721. By providing the rotating ring 716 and the gear ring 717, when the gear 710 rotates, the gear ring 717 can drive the rotating ring 716 and the rotating cylinder 719 to rotate, thereby making the coal and gangue on the outer surface of the air cylinder 720 rotate and fall into the inner cavity of the bent pipe 4. By providing the stirring plate 721, when the air cylinder 720 rotates, air flow can be generated in the inner cavity.This allows slag and dust to enter the inner cavity of the communication port 712.

[0045] The outer surface of the discharge port 83 is provided with a track groove, and the outer surface of the discharge port 83 is fixedly connected with a third limiting ring 88, and the outer surface of the sliding frame 84 is fixedly connected with a sliding rod 810, and the sliding rod 810 is slidably connected to the track groove provided on the outer surface of the discharge port 83, and the sliding rod 810 is slidably connected to the inner circle of the third limiting ring 88.

By setting the squeezing ball 812, after too much coal and gangue accumulate in the inner cavity of the sliding frame 84, the squeezing ball 812 can be brought into contact with the squeezing sleeve 87, so that the connecting disk 86 is squeezed and the end of the blocking plate 853 is tilted.

[0046] Working principle: When in use, the operator moves the frame 3 so that the top of the curved pipe 4 is stacked with the discharge end of the first conveyor 1, the bottom end of the curved pipe 4 is aligned with the upper surface of the conveyor belt of the second conveyor 2, and the roller 73 is in contact with the lower surface of the conveyor belt of the first conveyor 1, and the installation of the unloading device is completed; when working, the first conveyor 1 starts to work and moves the coal and gangue on the upper surface to the end of the conveyor belt, and then the coal and gangue fall in a parabola to the top of the curved pipe 4, and then the coal and gangue are in contact with the arc frame 63. When the coal and gangue collide with the arc frame 63, the arc frame 63 and the first rotating column 62 will rotate, thereby unloading the impact force of the coal and gangue, and then the coal and gangue fall into the inner cavity of the curved pipe 4 and contact the outer surface of the air cylinder 720. When the first conveyor 1 is working, the roller 73 rotates due to friction, The first roller 74 and the second roller 711 rotate, and finally the gear 710 drives the gear ring 717 to rotate, and finally the air cylinder 720 rotates, so that the dust and slag in the coal and gangue pass through the holes on the outer surface of the air cylinder 720 and enter the interior. Then, under the influence of the air flow generated by the rotation of the stirring plate 721, the dust enters the connecting port 712 and enters the inner cavity of the slag discharge port 714 through the connecting pipe 713. At the same time, the rotation of the air cylinder 720 will force the coal and gangue into the inner cavity of the bent pipe 4 and fall to the bottom. Then, the coal and gangue come into contact with the baffle plate 853. As the coal and gangue accumulate, the sliding frame 84 moves in the inner cavity of the discharge port 83 until the extrusion sleeve 87 is squeezed by the extrusion ball 812, thereby increasing the gap between the multiple baffle plates 853, allowing the coal and gangue to leak out and fall onto the upper surface of the conveyor belt of the second conveyor 2, completing the unloading of the coal and gangue.
