A back ear breakage reinforcement rib assembly for a bulldozer blade

Abstract

The utility model relates to bulldozing shovel installation technical field discloses a kind of back ear plate anti-fracture reinforcing rib assemblies of bulldozing shovel, including bulldozing shovel, reinforcing member is set between two supporting arms, two ends of the side of reinforcing member away from bulldozing shovel are respectively fixedly set one ear plate, reinforcing member includes reinforcing frame and two linkage rods, reinforcing frame is fixedly set between two supporting arms and ear plate, two linkage rods are crossly set in reinforcing frame, damping member is connected between two linkage rods, one buffer is respectively arranged in the both ends of reinforcing frame, reinforcing frame supports supporting arm and ear plate, rib plate supports bulldozing shovel and reinforcing frame form longitudinal supporting force, reinforcing frame cooperates the two linkage rods of cross arrangement and forms diamond space and cooperates spring damper to respond the transverse shear force between two ear plates, support ear plate and bulldozing shovel from longitudinal transverse two directions, and stress dispersion forms multidirectional support, to avoid ear plate fracture caused by local overload.
