COMB FOR STONE-PICKING MACHINE Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: comb has rigid curved teeth arranged at an angle to ground surface, and additional teeth pivotally positioned on shaft in spaces between rigid curved teeth. Pivotal shaft carrying additional teeth is positioned in area adjoining to teeth curvature. Each additional tooth is spring-loaded and equipped with upper and lower stops rigidly attached to teeth for pressing lower stop to comb teeth profiled surfaces during gripping of stone. During gripping of stone, profile of additional teeth makes flush with profile of rigid curved teeth of comb. Angle of opening of rigid curved teeth is greater than that of additional curved teeth. Pivotally arranged teeth have L-shaped profile.

EFFECT: simplified construction and increased extent of removal of soil adhered to working tools.
