FIELD: mechanics. ^ SUBSTANCE: drag device consists of supporting structure (3) for maintaining the drag device across conveyor belt, overlaps to the full extent the width of conveyor belt and consists of individual drag sections (1') covered with flexible material. Each section consists of a body with drag surface (4) resting on conveyor belt. Drag surface of each section is elastically attached to the supporting structure. Drag device is installed in a holder thus providing the possibility of bending. On drag device there provided are adjusting devices for holding different parts of the drag device down to conveyor belt. ^ EFFECT: providing adjustment of the drag device shape as to conveyor belt. ^ 45 cl, 8 dwg |
