Definitions

  • the invention relates to a grain peeling machine with two peeling rollers, one of which is mounted fixed to the frame, of which the other is mounted in a first direction to the frame-fixed peeling roll movable in an adjustment, and together form a peeling gap, which the material to be peeled by means of a Chute is fed, which is trackable during wear of the rollers in the peeling gap.
  • the invention is based on a known grain peeling machine with two peeling rollers, one of which is mounted fixed to the frame, of which the other is mounted in a first direction to the frame-fixed peeling roll movable in an adjusting element, and which together a peeling gap form, to which the material to be husked is fed by means of a chute, which is trackable during the wear of the peeling rollers the peeling gap and in a second, to the first parallel direction ( EP 0 820 814 B2 . FIG. 1 ).
  • the solution according to the invention is that the adjusting element is displaceable in the first direction and on the frame, a lever is pivotally mounted on a first pivot axis, which is aligned substantially perpendicular to the second direction and at a distance from the first pivot axis with a second pivot axis and is provided on the same side of the first pivot axis at a double distance from the same with a third pivot axis, and that the second pivot axis with the chute and the third pivot axis are pivotally connected to the adjusting element.
  • the invention is based on a grain peeling machine with two peeling rollers, one of which is mounted fixed to the frame, of which the other is mounted in a first direction to the frame-fixed peeling roll movable in a displaceable in the first direction adjusting element, and which together form a peeling gap, which the material to be peeled is fed by means of a chute during wear the peeling rollers track the peeling gap and can be pivoted about a pivot axis parallel to the axes of the peeling rollers ( EP 1 084 750 A1 ).
  • the solution according to the invention consists in this embodiment in that on the frame, a lever is pivotally mounted on a first pivot axis, which is aligned substantially perpendicular to the first direction and at a distance from the first pivot axis with a second pivot axis and on the same side of the first pivot axis is provided at a double distance from the same with a third pivot axis, and that the second pivot axis are pivotally connected to the peeling rollers facing the end of the chute and the third pivot axis with the adjusting element.
  • the invention is based on the recognition that both peeling rollers wear out substantially the same, so that the peeling gap shifts by a distance which corresponds to half the displacement of the movable peeling roller.
  • the wear of the peeling rollers will not always be uniform, since the faster rotating peeling roller wears faster.
  • the peeling rollers are provided with separate drives, which are controllable so that alternately one or the other peeling roller is driven faster than the other or one.
  • the change between the two drive states takes place at regular time intervals.
  • At least one of the peeling rollers is provided with a sensor for measuring the wear.
  • the change takes place between the two drive states on the basis of the measurement of the wear. For example, if only the measurement of the wear on one of the peeling rollers, so could each be switched if the wear of this peeling roller has assumed a certain extent.
  • the movably mounted peeling roller is biased by spring force against the frame-mounted peeling roller.
  • the movably mounted peeling roller is biased by pneumatic or hydraulic cylinder against the frame-mounted peeling roller.
  • the chute is displaceable in at least the center distance of the guide elements in a direction and back which is parallel to the axes of the peeling rollers, or that the chute is pivotable such that you the rollers virtualbartess end performs a corresponding movement.
  • the peeling rollers can be cooled with air, which is passed through the drive shafts designed as hollow shafts in the interior of the peeling rollers.
  • the tilt of the chute is adjustable. This makes it possible to adapt to the products.
  • FIG. 1 In a front view, partially broken away, there is shown a first embodiment of a grain peeling machine of the invention.
  • the grain peeling machine has a frame 1, in which a first peeling roller 2 covered with a rubber layer is mounted rotatably driven. A second likewise driven and coated with a rubber layer peeling roller 3 is rotatably mounted on an adjusting element 4, which can be moved with a sliding guide 5 in the direction of the connecting line of the two peeling rollers 2, 3. Both peeling rollers rotate in opposite directions of rotation at different speeds, alternately rotating one and the other faster. On the adjusting element 4, a pressure is exerted by a pneumatic cylinder 6 so as to press the peeling roller 3 against the peeling roller 2.
  • the grains are filled into a hopper 7, wherein by means 8 and sensors 9 on the one hand the level is controlled and on the other hand it is ensured that the grains substantially in a grain-thick layer via a chute 10 in the peeling gap 11 between the two peeling rollers 2, 3 arrive.
  • the chute 10 is movable with a sliding guide 12 parallel to the direction of the connecting line of the axes of the two peeling rollers 2, 3.
  • a lever 14 is pivotally mounted, which has a second pivot axis 15 and a third pivot axis 16 has.
  • the pivot axis 15 is arranged exactly in the middle between the pivot axes 13 and 16.
  • the lever 14 is connected to the pivot axis 15 via a rod-shaped element 17 with the chute 10.
  • the lever 14 is connected via a rod-shaped element 18 with the adjusting element 4.
  • the peeling roller 3 in FIG. 1 to the bottom left the lever 14 is pivoted, and the slide 10 is due to the distance ratios of 1: 2 between the pivot axes 13 and 15 on the one hand and 13 and 16 on the other hand shifted by half the displacement of the peeling roller 3, so that the chute continues exactly points to the peeling gap 11 and the grains to be peeled tangentially on the surfaces of the two peeling rollers 2, 3 impinge.
  • the chute 10 is provided with guide elements, not shown in the figure, in this embodiment with grooves extending from top to bottom perpendicular to the peeling gap 11 over the entire width of the chute 10. Through these grooves elongated grains are aligned so that their longitudinal axes in the direction of the grooves and thus extend perpendicular to the peeling gap.
  • the slide 10 and its slide is doing by the in FIG. 2 shown drive element 27 in a sliding guide 19 perpendicular to the plane of the paper FIG. 1 moved back and forth at least the channel width, so that the peeling rollers 2, 3 are subject to uniform wear and form no grooves there.
  • the same result can be achieved by pivoting the chute, in which the adjacent end of the rollers performs a corresponding movement.
  • a sensor is shown, with which the closure of the peeling roller 2 is measured.
  • a corresponding sensor could also be provided for the peeling roller 3. If a certain wear of one or both peeling rollers is detected, the drive is changed so that the hitherto faster-running peeling roller slower and the previously slow-running peeling roller runs faster to make the wear more uniform.
  • FIG. 2 shows a slightly different embodiment. It differs essentially from the embodiment of the FIG. 1 characterized in that although the chute 10 is connected via a rod-shaped element 17 with the lever 14, the lever 14 is not connected via a rod 18 with the adjusting element 4, but is articulated directly on the same. However, the corresponding pivot axis 16 should allow a certain movement in the longitudinal direction of the lever 14 and would therefore be fork-shaped, for example.
  • a motor 20 for the frame-mounted peeling roller 2 and a motor 21 for the movable peeling roller 3 is shown. The drive of the peeling roller 3 takes place via a belt drive 22nd
