TUNNELLING MACHINE Russian patent published in 2022 - IPC E21D9/12 E21F13/08 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used in a design of a scraper conveyor of a tunnelling machine. The apparatus comprises a scraper conveyor including a lifting section and a drive section, a rotary platform coupled with the unloading chute and installed rotatably in a horizontal plane. The rotary platform is placed above the drive section, rigidly coupled by a bracket with the unloading chute, and installed on a movable frame coupled by a hinge connection with the sidewalls of the drive section and equipped outside of at least one sidewall with a rack kinematically coupled so as to be movable in the vertical plane of the movable frame with an eccentric coupled rotatably in a vertical plane with the drive shaft of the drive section.

EFFECT: passability of the rock mass through the unloading chute is increased, labour intensity of assembly of the scraper conveyor is reduced.
