Description

Technical Field

[0001] The utility model relates to the technical field of coal blending machines, in particular to a coal material conveying mechanism suitable for a coal blending machine and the coal blending machine. Background Art

[0002] Hoppers play a crucial role in the fields of weighing and mixing, particularly in coal blending machines. A search revealed patent publication number CN207451011U, which discloses an automatic coal blending conveyor. This machine features a main conveyor belt with multiple hoppers positioned above it. Coal from each hopper first falls onto a corresponding secondary conveyor belt, then flows through the secondary conveyor belts and converges onto the main conveyor belt. Finally, the main conveyor belt delivers the coal to a mixing mechanism, completing the coal blending process.

[0003] However, existing coal blending machines have the following problems: Because the hoppers are positioned vertically above the main conveyor belt, increasing the number of hoppers also requires the number of secondary conveyor belts, causing the main conveyor belt to become excessively long. This excessive length reduces coal blending efficiency and increases space requirements, limiting the application scope of the coal blending machine. Utility Model Content
