Definitions

  • the invention relates to a tool for use in a comminution rotor of a comminution machine according to the preamble of claim 1.
  • Object of the present invention is therefore to provide a free-swinging tool whose parts subject to wear can be easily replaced by an operator.
  • the tool has a trained as a one-armed lever body, which is freely rotatable about an axis and at its free end a Tool head for receiving a replaceable wearing part, wherein the tool head comprises a lower and an upper clamping part, between which the wearing part by means of at least one clamping screw is lockable.
  • the wear part which may be a blade, for example, so the tool with its clamping screw can be pivoted radially outward that the clamping screw by an operator detachable and fixed by her wearing part is removable or interchangeable.
  • an upper and lower clamping part can be coupled by means of the clamping screw with the base body.
  • the tool can be coupled to the comminution rotor via the axle and by means of axle clamps and axle clamping screws.
  • the Achsklemmschrauben can be positioned with their screw heads radially outward to the crushing rotor, so that a loosening or tightening the screws from a corresponding radially outer region of the crushing rotor is easily possible.
  • the common center of gravity is provided by the interconnected upper and lower clamping parts, wearing part, clamping screw and body in a region between the axis and the free end of the tool. This ensures that during a rotation of the comminution rotor together with the tool provided thereon, the tool is pivoted radially outward relative to the comminution rotor by the centrifugal force acting thereon during rotation and can have a comminuting action in this radially outer area of the comminution rotor.
  • At least one sliding bush is provided for receiving the axle within the base body.
  • the main body or the tool can rotate freely about the rigid axis, wherein the slide bushing supports the rotational movement of the tool.
  • the sliding bushing can be lubricated via a lubrication access in the base body.
  • a lubricant for improving the rotational properties of the tool can be introduced in the contact region of the axis and sliding bush or base body.
  • the lubrication access is provided on a side opposite the wear part of the tool. This makes it possible to ensure that a valve provided, for example, at the lubrication access is removed from the region of the wearing part in which the cutting of the material to be comminuted takes place, thereby avoiding a collision or damaging the valve as far as possible.
  • the wearing part is the area of the tool farthest from the axis. In this way, it can be ensured that material to be comminuted introduced into the regions of the comminution rotor is first touched and comminuted by the consumable part during the rotation of the rotor.
  • the clamping screw can be screwed from below such that it does not protrude beyond the contours of the upper clamping part. In this way it can be ensured that the comminution takes place exclusively through the wearing part, which can be designed, for example, as a shredding blade, and the clamping screw does not collide with the material to be comminuted.
  • two radial bushings are provided on the axle for receiving the Achsklemmschrauben.
  • the Achsklemmschrauben can be passed through the axle clamp and act on this on the rigid axle.
  • FIG. 1a shows an inventive tool 1 for use in a crushing rotor of a crushing machine as used for example for the treatment of waste wood.
  • the tool 1 has a base body 2 which is freely rotatably mounted about the axis 3. At the free, ie in the representation of FIG. 1a upper end of the base body 2 is a tool head 4 for receiving a replaceable wearing part 5.
  • the tool head 4 is divided into a lower and an upper clamping part 7, 8, between which the wearing part 5 is determined by a clamping screw 9. It is conceivable that the base body 2 and the lower clamping part as shown in the figures in one piece or alternatively in two pieces are made. It is also conceivable to provide on the base body 2 a bulge, in which a thread for the clamping screw 9 is provided.
  • the upper and the lower clamping part 7, 8 can be screwed by means of the clamping screw 9 simultaneously with the base body 2.
  • the clamping screw 9 thus fulfills a multiple function.
  • There may be other components such as bearings or spacers are coupled by means of the clamping screw 9 with the base body 2.
  • the tool 1 is coupled via the axis 3 and by means of two axle clamps 10 and two Achsklemmschrauben 11 with the crushing rotor.
  • Axis 3, Achsklemmschrauben 11 and Achsklemmen 10 can be understood as parts of the tool. But it is also conceivable that tool without axis 3, Achsklemmschraube 11 and Achsklemmen 10 to understand as subject of the invention.
  • a lubricating access 13 In a lower region of the main body 2 is a lubricating access 13, via which an inner region of the base body 2, in which the axis 3 and sliding bushes 12 are arranged, can be lubricated.
  • the base body 2 together with the tool head 4 coupled thereto can oscillate freely about the axis 3.
  • the center of mass of the oscillatable part of the tool 1, ie without axis 3, Achsklemmschrauben 11 and Achsklemmen 10, is located approximately in the marked with the letter M area of the tool 1 and is located between the axis 3 and wearing part 5, which is substantially at the free End of the tool 1 is provided.
  • the sliding bush 12 which is only partially visible, comprises the axle 3 and supports it within a passage of the main body 2. This area can be lubricated via the lubricating access 13.
  • the clamping part 8 can be secured via a clamping screw 9 screwed in from below.
  • the clamping screw 9 does not extend beyond the outer contour of the tool 1 and can not collide with clippings and thereby be damaged or loosened.
  • the Achsklemmschrauben 11 clearly penetrate the axis 3, including two through-holes are formed by the axis 3 in the radial direction. These can run parallel.
  • FIG. 1b shows the same tool in another perspective view. All features except for the lubrication access 13, which is now not lying behind, are as in FIG. 1 to recognize a.
  • FIG. 2 shows an exploded view of the tool 1 with all previously mentioned components.
  • the upper clamping part 8 comprises an angled contact surface 8 ', which is in the assembled state of the tool 1 with the wearing part 5 in contact.
  • Upper clamping part 8, lower clamping part 7 and body 2 have bushings for the clamping screw 9, wherein in the upper clamping part 8, a corresponding thread for the screw 9 is provided.
  • a further passage 14 can be seen, which is part of the lubricating access 13.
  • the lubrication access 13 in this case comprises a valve 15, through which a lubricant can be introduced in the inner region of the main body 2.
  • the inner region 20 of the base body 2 receives lubricated in the embodiment shown two sliding bushes 12 which comprise the axis 3.
  • the axis 3 itself has two parallel and provided at their ends bushings, through the Achsklemmschrauben 11 for attachment of the tool 1 can be performed on the crushing rotor.
  • the axis 3 is supported rigidly and the main body 2 together with the tool head 4 can be freely pivoted about the axis 3.
  • a holding device may be provided which holds the wearing part 5 in position.
  • the holding device may be made of a different material than the base body and / or the clamping parts 7, 8 and be made for example of a more elastic material than this. As a result, a better grip of the wearing part 5 can be ensured.
  • the holding device can be connected by means of screws 31 with the base body 2 and with the lower clamping part 7.
  • FIG. 3 shows a crushing rotor of a crushing machine, in which a plurality of tools 1 in the region of the lateral surface of the cylindrical crushing rotor is arranged. If the crushing rotor is rotated in the circumferential direction for performing comminution work, centrifugal forces acting on the tools 1, which cause the tools 1 as in the FIG. 3 shown, are arranged with their center of mass radially outward from the crushing motor. If the tools 1 collide with a part which is difficult to comminute, they can be rotated about their axis 3 due to their free bearing, and damage to the tools 1 can thus be avoided.
  • FIG. 4 shows a detail of a built-in a crushing rotor tool 1, which can be seen here, as the axle clamps 10 act on the axis 3 on a correspondingly shaped storage area of the crushing rotor.
  • the axle 3 is thereby clamped over the axle clamps 10 and by means of the axle clamping screw 11. If there is a collision of the tool 1 with good to be crushed Good, so sufficient space is provided in the field of crushing rotor, so that the tool 1 can rotate completely or almost completely about its axis 3 radially inward.
