COLLECTOR OF BULLDOZER EQUIPMENT OF EARTH MOVER Russian patent published in 2013 - IPC E02F9/22 

FIELD: construction.

SUBSTANCE: collector of bulldozer equipment of an earth mover is proposed, which comprises a body with radial holes for supply and discharge of working fluid, connected as capable of rotation and axial displacement with a blade frame. Inside the body there is a part of a fixed core, installed with a gap into eyes of the blade frame and stopped by the other part against rotation in a lever of a blade lifting mechanism. Besides, the body is equipped with a leash element with a through slot. The fixed core is made with circular grooves for installation of seals and circular bores, communicated with radial holes of the body and channels of supply and discharge of working fluid in the lever of the blade lifting mechanism and axial channels for transfer of working fluid from the lever of the blade lifting mechanism to the blade frame. At the same time the specified axial channels are closed with plugs with seals at the end side of the core and are pressed with a flange on bolts. Connection of the body with the blade frame is carried out by means of a threaded element screwed into the blade frame and stretching via the central axial hole installed into a cut slot of the leash element, a stop made in the form of a four-face rod with a base in the form of a square, with a support site perpendicular to its faces. Between the leash element and the stop in the radial direction there is a gap, the value of which is more than the total value of gaps between the outer surface of the core and inner surfaces of the blade frame eyes. Height from the surface joined with the blade frame to the support site of the stop is more than the thickness of the leash element, and the width of the stop is less than the width of the slot of the leash element.

EFFECT: increased operational resource of a collector due to elimination of direct transfer of loads from a movable part of a machine towards a fixed one.
