Definitions

  • the innovation relates to a filling device for a mixing machine driven by a tractor with a pivotable shovel which can be pivoted from a loading position into an unloading position located above the mixing machine via a lifting mechanism operated by the tractor of the mixing machine.
  • a filling device for mixing machines with a pivoting blade has already become known.
  • the blade is connected to the mixing machine via a swivel arm formed from a linkage.
  • the swivel arm As soon as the swivel arm is raised, the product falls into the mixing machine. It can be done here but hardly avoid that when the swivel arm is lifted, the filling material already slides off the bucket and falls outside the mixer and, under certain circumstances, also pollutes and ultimately damages the lifting device.
  • the inventor has therefore set himself the task of creating an expedient embodiment of the filling device in which the filling material no longer falls from the scoop into the mixer in free fall but can be fed continuously to the mixer on a predetermined path.
  • this is achieved in that the scoop is connected to a material feed chute and the pivot axis for the scoop is provided at the end of the material supply chute opposite the scoop and is connected to the mixer, optionally with a support point attached to it.
  • the material slide is provided on both sides with lateral boundary surfaces, which may be also continue along the blade surface.
  • the new bucket design also enables the hoist to be designed, which is specially adapted to the combination of bucket and material feed chute.
  • the lifting mechanism for pivoting the bucket has a lifting cylinder which is pivotally connected to the mixing machine and has a piston rod, at the free end of which one end of one leg of an angle lever is pivotally fastened, which is fixed to the mixing machine about an apex provided in its apex , if necessary arranged on its support frame pivot axis and moves with the end of its other leg along the bottom surface of the material feed chute along the bucket when the piston of the hoist extends from the lifting cylinder (when the working method is pressing) or is pulled into the lifting cylinder (pulling method of operation) ) while the angle lever rotates around its swivel axis and lifts the bucket into its unloading position.
  • skids or casters are provided at the end of the leg sliding along the bottom surface of the material feed chute.
  • a mixer 1 is mounted on a frame 2 and connected to a tractor (not shown).
  • a support frame 3 for a blade 4, which is connected to a material feed chute 5, is also firmly connected to the mixer 1.
  • the end of the material feed chute 5 remote from the blade 4 is attached to the support frame 3 so as to be pivotable about the pivot axis 7 via an extension 6.
  • the material feed chute 5 is provided laterally along its bottom surface 8 with a boundary surface 9, and in the region of the blade 4 there are lateral boundary surfaces 9a.
  • the boundary surfaces 9 and 9a are formed in one piece in the exemplary embodiment.
  • a lifting device 10 is fastened to the support frame 3 of the mixer 1.
  • the lifting device 10 comprises a lifting cylinder 12 with a piston rod 13 which is pivotably arranged at 11 on the support frame 3.
  • a leg 15a of a rigid angle lever 15 with the leg 15a and the pair of legs 15b is pivotably attached at 14.
  • the pair of legs 15b comprises two legs of equal length running parallel to one another at a distance from one another.
  • the apex 16 of the angle lever 15 serves as a pivot axis, which is also arranged in a stationary manner on the support frame 3.
  • the second pair of legs 15b protrudes lengthwise above the leg 15a and carries at its free end slide rollers 17 which rest on the bottom surface 8 of the material feed chute 5 and slide along the bottom surface 8 during the lifting movement of the blade 4.
  • the lifting movement of the blade 4 takes place by retracting the piston rod 13, which is in the extended state during the loading position of the blade 4.
  • the angle lever 15 rotates about its pivot axis 16
  • the pair of legs 15b lifts and takes the blade 4 with it upwards, while the sliding rollers 17 slide along the bottom surface 8 of the material feed chute 5 until the Bucket 4 is in its unloading position above the mixer 1 and the loaded product slides along the feed chute 5 into the mixer 1 without damaging the surroundings and, above all, the lifting mechanism itself.
  • the pivot point 7 of the pivotable blade 4 is higher than the upper edge of the mixer 1.
