Embodiment Construction

[0018] like figure 1 As shown, mining shovel 10 is supported by tracks 14 on a support surface or ground (not shown). Excavator 10 includes: a frame 22 that supports a boom 26 and a fluid source 28 (eg, a fluid pump or tank); an elongate member or stick 30 ; an attachment or bucket 34 that includes a pivot actuator 36 ; and fluid delivery system 38 . The frame 22 includes a rotatable structure for rotation about an axis of rotation (not shown) generally perpendicular to a plane corresponding to the slope of the support surface. The frame 22 also includes a hoisting drum 40 to wind up and pay out a cable or wire rope 42 .

[0019] The boom 26 includes: a first end 46 coupled to the frame 22 ; a second end 50 opposite the first end 46 ; a boom pulley 54 ; a saddle body 58 ; and a transport shaft 62 . A boom pulley 54 is coupled to the second end 50 of the boom 26 and guides the wire rope 42 over the second end 50 . The wire rope 42 is coupled to the bucket 34 by the traction...

Abstract

Fluid delivery system. An industrial machine includes: a frame supporting a fluid source and a boom; an arm; an attachment coupled to the arm; a hydraulic cylinder; An arm is movably coupled to the boom for translational and rotational movement relative to the boom. A hydraulic cylinder includes a first end and a second end, and the hydraulic cylinder defines a bore in fluid communication with a fluid source. A hydraulic rod is coupled to the arm and is slidably received within the hydraulic cylinder. The hydraulic rod includes ports and channels to provide fluid to the attachment. The ports provide fluid communication between the bore and the channel. The ports are located in the bore throughout the range of motion of the hydraulic rod relative to the cylinder.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of US Provisional Patent Application No. 61 / 716,072, filed October 19, 2012, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to industrial machines. In particular, the present invention relates to a fluid delivery system for a bulldozer attachment. Background technique [0004] A conventional rope shovel includes: a frame supporting a boom; and a handle coupled to the boom for rotational and translational movement. A dipper is attached to the stick, and the dipper is supported by a cable or wire rope that runs over one end of the boom. A wire rope is secured to a bail pivotally connected to the bucket. During the hoisting phase, the wire rope is reeled up by the winch drum, thereby lifting the bucket through the pile of material and breaking away a portion of the material. The orientat...
