  • Patent number: 6839988
    Abstract: An apparatus for drilling trenches in the ground comprising a main frame having two vertical main faces, a drilling assembly comprising a support disposed at the bottom of said frame, means for causing said drilling assembly to move in vertical translation relative to said main frame by applying a predetermined force to said drilling assembly relative to said main frame, and anchoring means mounted on said main faces for anchoring the main frame to the walls of said trench. The anchoring means comprise a plurality of deformable elements secured to said main faces of the top frame, means for injecting a fluid under pressure into said inflatable elements thereby applying a force between said main frame and the walls of the trench, and means enabling said fluid under pressure to escape from said inflatable elements whereby no force is transmitted between said main frame and the walls of the trench.

  • Patent number: 6839989
    Abstract: The invention provides apparatus for drilling trenches in the ground, the apparatus comprising a frame and a drilling assembly having a horizontal support plate connected to the bottom end of the frame, said plate supporting drilling tools disposed beneath said plate, said trench being filled with a drilling mud. The periphery of said plate has resilient sealing means for co-operating with the walls of the trench so as to provide at least partial sealing between said plate and the walls of the trench, and means for adjusting drilling mud flow rates from the portion of the trench situated above said plate to the portion of the trench situated beneath said plate, and also in the opposite direction.

  • Patent number: 6820358
    Abstract: A compact self-propelled vehicle for composting windrows of compost material found in cramped confines has a low frame forming a central tunnel for mounting a flow-through conveyor. A front pick-up end has a central-flow auger system for attacking into the windrow end-on along the long axis thereof. The conveyor that has a lower intake end immediately trailing the central-flow auger system and a high discharge end for back-depositing the discharged material back into windrow formation. Hence central-flow auger system breaks apart, disintegrates and/or stirs the dug-into material while ultimately accomplishing transfer of it onto the conveyor. In essence, the vehicle worms its way through the windrow by virtue of the wheels rolling through a temporary and traveling void created between the leading pick-up end and the back-deposited material discharged by the discharge end of the conveyor.

  • Publication number: 20030116330
    Abstract: A traveling rolling digger for sequential hole drilling or for producing sequential cultivated spots in soil. The traveling rolling digger includes at least one drilling shaft which is rotatable by a drive mechanism about a longitudinal shaft axis and has a rotating soil penetrating edge. The drilling shaft is mounted to roll about a horizontal shaft in a soil penetrating plane while the horizontal shaft moves in a direction of travel of the traveling rolling digger. The rotating drilling shaft enters the soil at an entry angle and digs into the soil while the horizontal shaft moves in the direction of travel and the drilling shaft continuously changes its angle relative to the soil from the entry angle to a vertical position.

  • Patent number: 6438874
    Abstract: A hydraulic rotary grinder for attachment to construction machinery such as an excavator, consisting of a rotating drum having a hollow core and a plurality of attached replaceable grinding tips. A hydraulic motor rotates the drum, and is secured within the hollow core and activated by the hydraulic system of the construction machinery. A planetary gearbox is associated with the hydraulic motor to provide speed changes. At least one weight within the hollow core provides shock absorption and additional mass to the rotating drum. A heat-absorbing liquid within the hollow core absorbs heat from the grinding operation and a seal prevents the heat-absorbing liquid from leaking out of the drum. A number of water nozzles may be mounted on the apparatus for dust suppression. A second hydraulic motor may be provided for increased torque and grinding capacity.

  • Patent number: 6435766
    Abstract: A method and apparatus for ground working. A first step involves providing an apparatus for ground working with telescopically extendible wheel supports which permit the height and angular orientation of the chassis to be adjusted to suit a contour of a ditch. A second step involves positioning the apparatus with at least one support wheel in the ditch and at least one support wheel on the road. A third step involves driving along the ditch broadcasting gravel from the ditch onto the road with the drum. Instead of hauling in replacement gravel from a remote site, gravel is reclaimed from the ditch and broadcast back onto the road.
