CHUTE SECTION FOR FACE CONVEYER PROVIDED WITH LOADING PLATFORM Russian patent published in 2006 - IPC E21C35/12 B65G19/28 

FIELD: conveyers comprising an impeller or a series of impellers carried by an endless traction element and arranged to move articles or materials over a supporting surface or underlying material.

SUBSTANCE: chute section of coal production rig has load-lifting shaft section and reverse stroke shaft section adapted for scraper chain conveyer guider receiving. Chute base is located between the sections. The chute base has fixing means arranged from embedding side and from face side at chute ends to receive connection member of chute sections, which connects adjacent chute sections with each other to provide tensile strength thereof. The chute also has guiding means to guide production machine, which moves along mining face plane, and deflected guiding sheet, which creates loading platform connected with chute section from mining face plane side and extending from bed to load-lifting shaft section. Degree of lower guiding sheet part folding relatively chute base exceeds that of upper guiding sheet part. The guiding sheet is provided with depressions formed at chute section ends. The depression sizes correspond to that of fixing means and/or connection means, which connect chute sections one to another. Lower part of guiding sheet defines bridge at lower edge. The bridge extends to chute section ends.

EFFECT: elimination of face conveyer lifting.
