Definitions

  • the invention relates to a partially cut cutting machine with a loading ramp for the cut pile and a swiveling cutting arm.
  • the cutting arm can be pivoted beyond the width of the cutting machine.
  • the pile, which is cut in the width of the loading ramp is picked up by the loading ramp and conveyed away by a continuous conveyor starting from the loading ramp, so-called lobster claws are provided on the loading ramp, which convey the pile to this continuous conveyor.
  • the loading ramp is designed so wide that it laterally projects beyond the cutting machine, this hinders the maneuverability of the cutting machine.
  • the width of the loading ramp is limited to the width of the cutting machine, the laterally cut pile is not taken up and hinders the work of the cutting machine.
  • the object of the invention is to remove at least a large part of the entire cut pile.
  • the invention consists essentially in that at least on one side of the cutting machine on the loading ramp or on the frame of the cutting machine is articulated an at least pivotable boom in the horizontal direction, which is equipped with a continuous conveyor. In this way it is possible to make the loading ramp so narrow that the maneuverability of the cutting machine is not impaired, and at least for the most part to remove the cut pile.
  • the continuous conveyor of the swiveling boom By means of the continuous conveyor of the swiveling boom, the pile of material that has been cut on the side of the cutting machine in the protruding positions of the cutting arm is fed to the loading ramp and removed via the loading ramp.
  • a drive is preferably provided for pivoting the boom in the horizontal direction, so that this boom can be brought into various protruding positions. It can also be moved by this swivel drive of the boom so that it pushes the pile before it to the loading ramp when swiveling forward.
  • the swivel drive is preferably formed according to the invention by at least one hydraulically extendable strut articulated on the loading ramp or on the frame of the cutting machine and on the boom.
  • the boom can preferably also be pivoted in the vertical direction about an approximately horizontal axis and is supported on the sole. The swiveling in the vertical direction also enables the boom to be folded up when not in use.
  • the boom according to the invention is expediently pivotable horizontally by approximately 90 °.
  • the drive motor for the continuous conveyor can be arranged on the loading ramp or on the vehicle frame. In this case, however, the power transmission presents considerable design difficulties due to the pivotable articulation of the boom.
  • the drive motor for the continuous conveyor for example formed by a hydraulic motor, is therefore preferably arranged at the protruding end of the boom.
  • the continuous conveyor is formed by a screw conveyor.
  • the boom can have a housing in which the screw conveyor is guided and which, based on the direction of travel of the cutting machine, is pulled up at least on the rear side via the axis of the screw, at least partially leaving the front of the screw free and on the front has a cutting lip. Through this cutting lip, the pile is picked up from the ground and fed to the screw conveyor, from which it is then gripped and conveyed to the loading ramp. But it can also be the continuous conveyor from a chain conveyor arranged on the boom be formed, which also feeds the bulk of the loading ramp.
  • the arrangement can be such that the boom in the area of the front end of the loading ramp is hinged to the side thereof and that the loading ramp in the area of the boom has inclined surfaces to be sloped to the side.
  • the pile picked up by the continuous conveyor of the boom is fed from the side of the loading ramp and, via the inclined surfaces, reaches the area of the lobster scissors, from which it is fed to the continuous conveyor of the cutting machine.
  • the boom can also be arranged on the loading ramp or on the vehicle frame in front of the cutting lip of the loading ramp. In this case the continuous conveyor of the boom conveys the pile in front of the loading ramp in the direction of travel of the cutting machine, so that the pile can be picked up by the cutting lip of the loading ramp.
  • the boom can simply rest on the sole, so that the continuous conveyor of the boom detects the pile lying to the side of the loading ramp.
  • a support element for example a skid or a wheel, can also be arranged on the sole at the protruding end of the arm for supporting the arm.
  • a swiveling boom to one side of the cutting machine.
  • the swiveling range of the cutting arm usually extends beyond the width of the loading ramp on both sides and therefore a boom is usually arranged on both sides of the cutting machine.
  • the booms can be pivoted backwards to the cutting machine so that they do not impair the maneuverability of the cutting machine.
  • 1 represents the crawler chassis of the cutting machine.
  • 2 is the loading ramp, the cutting lip of which is designated by 3.
  • 4 are the lobster scissors which bring the pile that has reached the loading ramp 2 to the continuous conveyor 5 of the cutting machine.
  • Booms 6 are articulated on the loading ramp 2 on both sides of the cutting machine and can be pivoted about a vertical axis 7 in the horizontal direction.
  • the swivel drive of such a boom is formed by a hydraulically extendable strut 8, which is articulated at 9 on the loading ramp 2 and at 10 on the boom 6.
  • the boom 6 is shown in the inoperative position articulated to the cutting machine.
  • the hydraulic strut 8 reaching the position 8'.
  • the boom can also be pivoted beyond the position shown in dashed lines.
  • 11 is a hydraulic drive motor for the shaft of the screw conveyor 12. In the operating position, this drive motor reaches position 11 '.
  • Fig? the articulation point by means of which the boom 6 is articulated to the loading ramp 2 is shown on a larger scale.
  • the boom 6 can be pivoted about the vertical axis 13 in the horizontal direction and can be pivoted about a horizontal axis 14 in the vertical direction.
  • the boom 6 is connected to the horizontal pivot axis 14.
  • Fig. 3 shows a section through the boom along line III-III of Fig. 1.
  • 12 is the worm and 16 is the shaft of the worm, which is driven by the motor 11.
  • 17 is a sheet metal housing which forms the frame of the boom 6. The direction of travel of the cutting machine is indicated by arrow 18.
  • the screw conveyor 12 is free and at the rear it is covered by the housing 17.
  • the housing 17 has a cutting lip 19 on the front, through which the pile lying on the sole is brought into the area of the screw conveyor 12 and is conveyed by it to the loading ramp 2.
  • the loading ramp 2 has an inclined surface 20, via which the pile conveyed by the screw conveyor 12 is pushed onto the loading ramp 2.
