Description

TECHNICAL FIELD

[0001] The utility model relates to ore conveying technical field, concretely is a novel belt conveyor discharge port structure. BACKGROUND

[0002] With the continuous growth of global industrialization and logistics transportation efficiency demand, as the core equipment of bulk material continuous conveying, the belt conveyor occupies an important position in the fields such as mine, port, thermal power plant, steel plant and cement plant. The efficiency, low energy consumption and long service life of the conveying system become the core direction of industry development. However, as the key node of material transfer, the discharge port of the belt conveyor has long existed structural design defects, leading to equipment wear, belt damage and high maintenance cost, which becomes the bottleneck problem of restricting the technical upgrading of the industry.

[0003] In the traditional belt conveying system, the discharge port usually adopts a guide chute or a chute structure, and the material flow direction is guided by adjusting the angle of the side baffle. However, this kind of design exposes the following technical problems in actual operation:

[0004] ‌First, the material is transported from the tail end of the upstream belt conveyor to the downstream belt conveyor by the inclined steel plate in the discharge port for guidance. However, the steel plate is in contact with the ore material for a long time, which will cause a high wear rate of the steel plate.

[0005] ‌Second, when the number of materials of the upstream belt conveyor changes, the downstream belt discharge point also changes, which may cause uneven stress of the downstream belt receiving point, resulting in deviation of the conveyor belt.

[0006] ‌Third, foreign object impact causes frequent belt scratch accidents. In the ore material transportation scene, the ore may contain long strip steel bars and other foreign objects left during construction. When the foreign object falls directly to the surface of the downstream belt from a high place, the main body of the foreign object will be stuck in the discharge port, and the bottom of the foreign object will be in contact with the downstream belt, causing the downstream conveyor belt to be scratched.

[0007] ‌Fourth, high drop impact accelerates equipment wear. The distance between the upstream belt conveyor and the downstream belt is in a high distance drop, and the greater the drop distance, the greater the impact force on the downstream belt. Large impact will greatly shorten the service life of the downstream conveyor belt. INVENTION CONTENTS
