MECHANISM FOR DISPLACEMENT OF SECTIONS OF SUPPORT AND CONVEYER Russian patent published in 2003 - IPC

FIELD: mining industry, powered complexes for underground mining of mineral resources. SUBSTANCE: mechanism for displacement of sections of support and conveyer includes interjoined displacement hydraulic jack coupled to section of support and pusher on which link with groove is anchored by means of pin perpendicular to plane of seam. Link is tied with the aid of pin installed in groove to section of conveyer which has guide. Height of profile of guide increases in direction of conveyer. Groove in link runs in longitudinal direction. Guide is mounted on conveyer for contact with lower surface of link while it travels relative to guide. Guide can be made separable and position of its profile with reference to conveyer can be changed with subsequent fixing of it in this position. EFFECT: enhanced force pressing share to ground, improved conditions for coal loading on to conveyer, diminished loss of coal, enhanced controllability over operation of equipment. 1 cl, 6 dwg
