Definitions

  • the invention relates to a movable cutting machine with a loading ramp, a loading ramp clearing device, a conveying means emanating from the loading ramp for the removal of the cut material and a drive motor for driving the conveying means, the conveying means being capable of being pivoted relative to one another or relative to the longitudinal axis of the Funding is angled sections.
  • the drive for the loading ramp clearing device which is usually formed by its lobster shears, from a chain star of the conveying means.
  • the funding extends into the area of the loading ramp, so that the front deflection star of the funding is mostly used to drive the loading ramp clearing device.
  • the drive for the conveying means also acts directly on the front deflecting star of the conveying means, special gears are required for this, since the output shaft for the drive of the loading ramp clearing device must also be connected to this gearing.
  • the arrangement of a drive for the funding in the area of the loading ramp is associated with the disadvantage that, on the one hand, there is only a small amount of space available and, on the other hand, special protection for the transmission and the drive at this exposed point, at which the gained one Rock occurs, is required. In the known designs, the drive was therefore mostly provided at the free rear end of the conveyor.
  • a disadvantage of this design is the fact that when the free end of the conveying means can be pivoted, the drive can come into collision with further conveying means and, furthermore, that a relatively heavy drive unit must be stored far outside the center of gravity of the cutting machine.
  • the swivel drive for the free end of the conveyor and the The drive for lifting and lowering the discharge end of the conveying means must be appropriately oversized in such designs in order to be able to raise, lower and pivot the weight of the drive unit for the conveying means.
  • the invention now aims to provide a compact and reliable training in which the drive unit for the funding can be better protected and drive energy for lifting, lowering and pivoting the free end or the dropping end of the funding can be saved.
  • the invention consists essentially in that the drive motor acts between the discharge end and the loading ramp, preferably essentially in the middle, on the lower run of the conveying means.
  • Such a design has the advantage that the relatively heavy drive unit can be stored closer to the center of gravity of the cutting machine, that the drive unit is located at a point where the lifting, lowering or pivoting paths of the conveying means are still relatively small, and appropriate protection of the drive unit is possible more easily.
  • the drive motor is arranged between the loading ramp and the articulation point for the lateral pivoting of the discharge end of the conveying means.
  • the funding usually initially runs in a straight line below the swiveling mechanism of the cutting arm in an area in which lateral swiveling is not yet permissible, and a swiveling axis is only provided for swiveling the discharge end after the rear end of the cutting machine.
  • the conveying means is driven via the lower run of the conveying means, the drive motor preferably interacting with at least one support roller which cooperates with this run on the side of the lower run of the conveying means opposite the engagement of the drive motor.
  • the drive motor, the gearbox and the support roller are mounted in a common carrier, which in turn can itself be arranged within the plan of the cutting machine frame, preferably near the rear end of the crawler chassis.
  • the carrier of the drive motor can be connected in a simple manner to the conveying means itself, preferably pivotably and fixable in the pivoting position to the conveying trough.
  • Such a carrier can have bearing points for the attack of a drive formed by hydraulic cylinder piston units for lifting and lowering the conveying means in a simple manner.
  • the support roller can be resiliently pressable against the lower run of the conveyor.
  • the axis of the support roller is advantageously arranged lower than the axis of the drive chain star relative to the longitudinal axis of the conveyor.
  • FIG. 1 shows a schematic side view of an embodiment of a conveyor of a known type arranged on a cutting machine and
  • FIG. 2 shows the drive arrangement according to the invention in an enlarged view.
  • the conveyor consists of a front part of a conveyor trough 1, which is arranged in the region of a caterpillar undercarriage (not shown) of a cutting machine and on which a rear part 3 of the conveyor trough is articulated laterally pivotably about a vertical bolt 2.
  • the front part like the rear part 3 of the conveyor trough, can be lifted together in the vertical direction, as indicated by dashed lines.
  • the drive is arranged at the rear end of the conveyor, the axis of the drive star being designated by 4, which is mounted in a carriage 5, which is displaceable on the rear part 3 of the conveyor trough in the direction of conveyance indicated by the arrow.
  • the carriage 5 is supported by a cylinder-piston unit 7 against the conveying direction 6 against the rear part 3 of the conveying trough.
  • the piston rod 8 is articulated on the carriage 5 and the cylinder 9 is fastened to the rear part of the conveyor trough.
  • 10 are Carriers, which are connected by the chain 11. These drivers slide on the bottom 12 of the conveyor trough and interact with the side walls 13 thereof. The chain is thus guided in the middle of the conveyor troughs 1 and 3 by the drivers 10. At the bend point 14, the side walls are formed by flexible steel strips. In the event of an angle from the straight-line position, ie when pivoting about the axis formed by the bolt 2, the chain path is shortened.
  • a piston rod 16 of a cylinder-piston unit 17 is articulated on the rear pivotable part 3 of the conveyor trough by means of a bolt 18.
  • the cylinder 19 of the cylinder-piston unit 17 is articulated on the front part 1 of the conveyor trough by means of a bolt 20.
  • the rear end of the cutting machine is indicated at 21.
  • FIG. 2 the side view in the area of the rear end 21 of the cutting machine is shown enlarged.
  • the chain strand 22 at the bottom of the chain is guided over a drive chain star 23 which is arranged in the region of the rear end 21 of the cutting machine.
  • a support roller 24 is provided, which can be spring-loaded in a simple manner in order to ensure the required chain tension.
  • the drive motor for the drive chain star 23 is indicated schematically at 25.
  • a hydraulic cylinder piston unit 26 is provided for raising and lowering the front part 1 of the conveyor trough. This cylinder-piston unit 26 can equally well engage the carrier 27 of the drive unit 25 and the drive chain star 23.
  • the carrier 27 is connected to the conveyor trough.
  • the cutting machine has in the region of its rear end 21 a support shoe 28 which can be pressed against the sole via a cylinder piston unit 29.
  • a relatively stable and heavy drive unit can be provided, which is protected against damage, without the cylinder-piston unit 26 having to be dimensioned much larger for raising and lowering the conveyor trough.
  • the weight of the drive is derived via a relatively short lever path and, in the event of attack by the cylinder piston unit 26, directly on the carrier 27 via the smallest possible lever path into the cylinder piston unit 26, and the drive remains in a relatively protected position even when the rear part 3 of the conveyor trough is pivoted .
  • the rear end of the chain undercarriage of the cutting machine is indicated at 30.
  • the machine operator's seat is shown at 31 to illustrate the size relationships of the drive.
