Patent number: 6508608Abstract: An apparatus and method are provided for treating base materials, such as ore of a leach pad in a precious metal mining operation. A tilling head of the apparatus includes a cutter having a cutting face for engaging and loosening compacted base materials. The tilling head is extended into the base material down to a tilling depth so that the cutter moves loosened base material up and over the top of the tiller apparatus before depositing it in a pile opposite the cutting face. The loosened base material is deposited a distance from the tilling head that is sufficient to create a void between the tilling head and the pile that extends down to the tilling depth to prevent the loosened base material from being disturbed by the tilling head. The tilling head can be positioned so that the cutting face undercuts the base material to thereby assist the cutter in moving the loosened base material and increase the distance between the tilling head and the pile.Type: GrantFiled: August 1, 2000Date of Patent: January 21, 2003Assignee: Tracsaw Manufacturing, Inc.Inventors: Ron Nilson, Thomas C.

Patent number: 6318930Abstract: A trench-padding method and apparatus provide a more efficient, cost efficient process of obtaining a maximal amount of padding material from material excavated from a trench, and where selected, provide for trenching. The trench-padding apparatus includes a lead assembly that includes a feeder housing having a front rotating unit with protrusions. The feeder housing may be configured to excavate the trench or alternatively, to scoop up previously excavated material. The front rotating unit is attached to a frame of the trench-padding apparatus immediately in front of an elevator device, and the front rotating unit forces clumps of the excavated material between the front rotating unit and a base of the feeder housing to aid in reducing clump size. The method operates in the manner of the trench-padding apparatus.Type: GrantFiled: February 19, 1999Date of Patent: November 20, 2001Inventor: Erik D. Scudder

Patent number: 5421108Abstract: A padding machine (10, 100) which is capable of separating materials in a spoils bank beside a trench into coarser materials, which are redeposited in the spoils bank behind the machine, and finer materials which are conveyed to the trench for padding the pipeline. The machine includes a conveyor with a conveyor chain which moves around the perimeter of the machine. Material caught by the scraper blade (28) is conveyed by the conveyor chain along a belly pan (70) and thereafter over a plurality of grizzly bars (72). Coarser material which will not pass through the grizzly bars is conveyed by the conveyor chain (56) to the rearward end of the machine and dumped off the rearward end of the machine back to the ground. The finer materials passing through the grizzly bars are again separated by a vibrator unit (76, 104). The depth of the scraper blade can be adjusted by pivoting the entire frame about the wheels (34) at the rearward end of the frame by a hydraulic cylinder (48) pivoting the towing arm (38).Type: GrantFiled: February 18, 1993Date of Patent: June 6, 1995Assignee: Capitan Trencher Corp.Inventor: Teddy L.

Patent number: 5228220Abstract: A continuous excavating and loading machine having a front mounted rotary digging element divided into sections to allow cantilevered support, digs a width greater than that of any other part of the machine so that the machine may advance on the surface it has cut. The digging element is driven by digging chains which also break up material in their path so that the full digging face is excavated. Excavated material is discharged outwardly from the digging element by both centrifugal force and gravity after rotation past top center. The excavated material falls onto a conveyor system to be elevated and transported to the rear of the machine for transfer to appropriate carriers. A moldboard blade trims surface irregularities and pushes passed material forward into the bucket wheel. A movable skid plate, held against the cut surface by a constant force, supports digging torque reaction loads and damping is provided for shock conditions.Type: GrantFiled: December 23, 1991Date of Patent: July 20, 1993Inventor: John F. Bryan, Jr.

Patent number: RE35088Abstract: A trenching machine has an elongated chain type digging implement that is pivotally mounted for vertical adjustment and movably mounted to a main frame thereof for lateral adjustment. The pivot coincides with the power shaft, and the elongated chain type digging implement is supported so it can be moved laterally in order to position the digging implement adjacent either side of the digging machine main frame and anywhere therebetween to excavate closely adjacent to buildings and other structures. The mechanism for moving the digging implement can be manually actuated by a hand crank arrangement. The main frame of the machine can be tilted laterally to either side to align the digging implement to excavate a vertical ditch. The tilting of the machine also makes it easier to manually move the digging implement laterally.Type: GrantFiled: July 23, 1993Date of Patent: November 14, 1995Assignee: Trencor Jetco, Inc.Inventor: Jerry F.
