Description

Technical Field

[0001] The present invention relates to the technical field of conveyor belt transportation, and particularly to an energy-saving chute for a single-line transfer conveyor belt. Background Art

[0002] During the coal preparation process, different equipment is basically arranged step by step from the top floor of the plant downwards to ensure smooth material flow. Belt conveyors are commonly used material conveying equipment, and chutes, as key components connecting different belt conveyors, play an important role in guiding the flow direction of materials. The traditional belt conveyor chute has a relatively simple structure, which is welded with flat steel plates. Usually, it simply guides materials from the upper-level belt conveyor to the lower-level belt conveyor, and the materials fall onto the belt surface of the lower-level belt conveyor at a nearly vertical speed direction, without making full use of the kinetic energy and potential energy of the materials when leaving the upper-level belt conveyor. When the materials rush towards the lower-level belt conveyor at a speed perpendicular to the belt surface, the kinetic energy and potential energy increase the pressure on the belt surface of the lower-level belt conveyor, and then increase the friction between the belt surface and the buffer bed below the belt surface; in the moving direction of the lower-level belt conveyor, the speed of the materials suddenly increases from 0, that is, in the moving direction of the belt conveyor, the kinetic energy suddenly increases from 0, which requires the motor of the lower-level belt conveyor to indirectly supply energy. These two factors cause the lower-level belt conveyor to consume a large amount of energy, increase production costs, and have low energy utilization efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide an energy-saving chute for a single-line transfer conveyor belt to solve the above problems, make full use of the kinetic energy and potential energy of materials, reduce the operating load of the lower-level belt conveyor, and improve energy utilization efficiency.
