Publication number: 20180168115Abstract: One stump cutter cutting wheel disclosed herein includes a wheel structure having left and right sides and being rotatable about a central axis extending between the left and right sides. The left and right sides define receptacles having depths measured in an orientation extending along the axis. Cutter assemblies are mounted to the wheel structure and include cutters mounted to cutter holders. The cutter holders include base portions that fit within the receptacles, and the base portions each define at least one fastener opening. The base portions further define base thicknesses measured in the orientation extending along the axis. The receptacle depths are at least 0.25 times as large as the base thicknesses such that no more than 75 percent of the base thicknesses extend laterally outside the receptacles. Fasteners secure the cutter holders to the wheel structure and extend through the fastener openings defined by the base portions.Type: ApplicationFiled: February 13, 2018Publication date: June 21, 2018Inventors: CLINT WEINBERG, LOUIS C. HARTKE

Publication number: 20130008718Abstract: A tunneling apparatus is disclosed. The tunneling apparatus includes a drill string formed by a plurality of drill string sections. The drill string has a proximal end and a distal end. The tunneling apparatus also includes a drill head mounted at the distal end of the drill string, the drill head including a cutting unit, a rotational driver that provides torque for rotating the cutting unit, and a thrust driver for applying thrust to the drill string. The tunneling apparatus further includes a vacuum system for withdrawing spoils generated by the cutting unit during operation of the tunneling apparatus and a drilling fluid system for providing drilling fluid to adjacent the cutting unit during operation of the tunneling apparatus. The tunneling apparatus includes a control system that allows an operator to select between a drilling mode and a break-out mode.Type: ApplicationFiled: March 26, 2010Publication date: January 10, 2013Applicant: Vermeer Manufacturing CompanyInventors: Melvin Nguyen, John Wesley Philbrook, Andis Salins, Stuart Harrison, Louis C. Hartke, Matthew Stephen Vos, Robert Hoch Shuman, V, Hans Kelpe, Douglas Eugene See, JR., Jeffrey Scieszinski

Patent number: 7694751Abstract: A biased door member is provided in an external wall of a drill rod supply magazine mounted on a horizontal directional drilling (HDD) machine. The door member swings inwardly from a first position parallel to the external wall to a second position within the distal column. At least one cut-out is formed in the external wall at the bottom of the retaining guides located at the longitudinal ends of the magazine. The cut-out creates a window through which the added drill rod is inserted. In operation, a drill rod is moved through the biased door member and window cut-outs into the distal column. The pocket of a rod transfer mechanism is positioned below the last column, and a rod lifter lowers the added drill rod into the pocket. The rod transfer mechanism then moves the added drill rod into alignment with the drill string.Type: GrantFiled: July 12, 2007Date of Patent: April 13, 2010Assignee: Vermeer Manufacturing CompanyInventor: Louis C.
