Description

Technical Field

[0001] The utility model relates to a conveyor belt transfer funnel which can buffer transfer materials when an upper conveyor belt and a lower conveyor belt are transferred, and belongs to the technical field of conveyor belt equipment. Background Art

[0002] Conveyor belts are important equipment for conveying bulk materials. A single conveyor belt can only transport materials in a straight line. When the material transportation direction needs to be changed, different conveyor belts are usually required for transfer. A transfer funnel needs to be installed between the two conveyor belts. The upper conveyor conveys the materials to the lower conveyor belt through the transfer funnel to complete the material transfer. At present, general transfer funnels all adopt ordinary funnel shapes and structures, which makes the material drop position of the upper conveyor belt often deviate from the center of the lower conveyor belt when it passes through the transfer funnel to the lower conveyor belt, causing the lower conveyor belt to deviate, spill, and other problems. At the same time, if the distance between the upper conveyor belt and the lower conveyor belt is large, the material passing through the transfer funnel will have a greater impact on the lower conveyor belt under the action of gravity, which will not only cause spillage, but also easily cause damage to the conveyor belt. Therefore, it is very necessary to design a transfer funnel that can buffer the transfer materials between conveyor belts to avoid conveyor belt deviation and material loss. Utility Model Content
