Description

Technical Field

[0001] The present invention relates to the technical field of conveyor belt transmission, in particular to an energy-saving chute for converting a single-line to a multi-line conveyor belt. Background Art

[0002] During the coal preparation process, various equipment is typically arranged in a step-by-step manner, from the top floor downward, to ensure smooth material flow. Conveyors are commonly used as material conveying equipment, and chutes, as key components connecting different conveyors, play a crucial role in guiding material flow. Traditional conveyor chutes are relatively simple, constructed from flat, welded steel plates. They typically simply guide material from one conveyor belt to the next, dropping it onto the lower conveyor belt at a near-vertical speed. This fails to fully utilize the kinetic and potential energy of the material as it leaves the upper conveyor belt. As the material rushes toward the lower conveyor belt at a speed perpendicular to the belt surface, the kinetic and potential energy exerts pressure on the lower conveyor belt, increasing friction between the belt surface and the buffer bed beneath it. Furthermore, the material's speed suddenly increases from zero in the direction of the lower conveyor belt's motion, meaning its kinetic energy suddenly increases from zero. This necessitates indirect energy transfer from the lower conveyor belt's motor. These two factors result in significant energy consumption by the lower conveyor belt, increasing production costs and lowering energy efficiency. Summary of the Invention
