Definitions

  • the advantages achieved with the invention are, in particular, that the cutting material work can be continued economically and ecologically efficiently at every location of the mobile sawmill. It saves time when processing the cut material and thus energy to operate the sawmill with diesel fuel, which reduces emissions by an equivalent amount. Overall, the productivity and competitiveness of the mobile sawmill are increased.
  • the foldable cuttings receptacle consists of a structural steel base frame and an attached frame with folding arms and an integrated chain conveyor for removing the cuttings from the saw bed of the mobile sawmill.
  • the folding arms are driven by hydraulic cylinders.
  • the chain is conveyed with a hydraulic motor via the feed through the mobile sawmill.
  • the foldable clippings intake can be attached to or separated from the mobile sawmill with a quick release fastener.
  • a chain deflector is installed, where the chain is deflected via a sprocket ( Fig. 1 ).
  • the sprocket is fastened with a feather key on a shaft that is supported by two bearings.
  • the bearings are installed with screw connections on the foldable arms.
  • the chain is driven by the double sprocket and guided through a guide rail and a chain tensioner.
  • the double chain wheel is attached to a shaft with feather keys.
  • the shaft goes through all three pivot points and is supported on 12 bearings, four bearings per pivot point.
  • the outer bearings are attached to the foldable arms with screw connections.
  • the bearings on the inside are fastened to the clippings holder with screw connections.
  • the chain runs on the other ring of the double chain wheel and is deflected at the chain deflection at the end of the clippings pick-up.
  • the chain sprocket of the chain deflector is attached to a shaft with a feather key.
  • the shaft runs in two bearings that are attached to the clippings holder with screw connections.
  • the chain can be tensioned by moving the chain deflection in the elongated holes of the clippings acceptance. ( Fig. 4 )
  • the clippings holder and the pivot points are welded to the frame, which consists of square profiles ( Fig. 2 ).
  • Cylinder mounting plates are welded to the outer arms and the vertical profiles of the frame, between which the cylinders are installed ( Fig. 3 ).
  • claws are welded that engage in the lifting plate on a bolt.
  • the lifting plate is attached to a bolt that is inserted into two metal sheets. ( Fig. 7 )
  • the sheets are welded to the square tube.
  • a cylinder mounting plate is welded to the square beam tube ( Fig. 5 ).
  • the frame cylinders are fastened with bolts between the cylinder mounting plates and the lifting plate ( Fig. 5 ).
  • the square beam tube is attached to the mobile saw with clamping plates ( Fig. 5 +6).
  • the frame of the clippings reception is reinforced by stiffening profiles that are welded into the frame.
  • Five alignment cylinders are attached to the sides of the frame.
  • the motor bracket and the hydraulic motor are fastened to the middle support with screw connections.
  • the foldable clippings holder is located directly next to the mobile sawmill and is connected to the frame of the mobile sawmill by means of a quick-release fastener.
  • the hydraulic drive of the foldable clippings holder is connected to the hydraulic line of the mobile sawmill by means of a quick coupling and is then ready for use.
  • the foldable clippings holder When sawing the first rind as well as the first board from a tree trunk through the mobile sawmill, the foldable clippings holder remains in its basic position, the swiveling arms are positioned vertically upwards at a right angle to the saw bed.
  • the saw head of the mobile sawmill moves back to its rest position, and the foldable arms of the cuttings receptacle are folded out 90 degrees horizontally to the saw bed by means of the hydraulically driven cylinders.
  • the tree trunk is rotated, causing the first rind and the first board to fall onto the folding arms. Now both are conveyed to the cuttings tray as far as the stop by operating the chain drive.
  • the folding arms are folded vertically upwards by 90 degrees and the second rind and the second board are sawn. In the meantime, the cuttings can be cleared from the cuttings tray. This process is repeated up to and including the third rind and the third board.
  • the foldable clippings holder can be opened completely onto the saw bed of the mobile sawmill using two cylinders attached to the left and right of the base frame, which are also driven by hydraulics, and can thus be transported together with the sawmill.
  • the foldable clippings holder can be uncoupled from the frame of the mobile sawmill by releasing the quick release coupling of the hydraulic line and the quick release fasteners.
