Definitions

  • the present invention relates to a portable crushing machine having a rotor space, at least one guided in the rotor chamber conveyor belt for bringing to shred Good, a blower for the removal of wood chips, a preferably stationary counter ledge, run past the cleaver and a rotatably mounted in the rotor chamber hacking rotor.
  • Such crusher are already known.
  • the cutting edges of the chopping knives are arranged parallel to the drive shaft and the counter bar, so that the cutting edges strike at the same time on the wood over its entire length.
  • the hacking jerky designed and the hacking rotor requires a high torque.
  • the wear of the cleaver is high.
  • crushing machines are known, the tiller rotor is cylindrical, and in which the cutting edges of the cleaver are aligned at an angle to the counter bar.
  • the object of the present invention is therefore to specify a comminution machine with which a jerk-free and energy-saving chopping operation is possible, wherein the chippings can be processed as small as possible in a chopping process.
  • the object is achieved by a crushing machine according to claim 1.
  • the cutting edges of the chopping knives are not parallel to the axis of rotation of the chopping rotor, but also arranged conically. Consequently, the cutting edges do not strike the wood along their entire length at the same time. In this hacking process, therefore, designed the hacking smoother and without interruption, the hack rotor does not require high torque. Thus, the wear of the cutting edge, which is no longer claimed to such a degree on impact decreases.
  • a chipping rotor has a plurality of segments, these segments being arranged along the axis of rotation of the chopping rotor, on disks or the like. Two adjacent steel discs are connected by a steel plate to a cutting segment, which will be referred to in the following as a segment.
  • At least one cleaver is arranged on the outer edge of the segment.
  • the chopping knives are mounted on a steel plate connecting in each case two adjacent steel disks, which at the same time serves as a support plate of the chopping knives, wherein the support plate is parallel to a tangential plane of the lateral surface of the chopping rotor.
  • Such segments provide a convenient connection between the chopping knives and the axis of rotation of the chopping rotor and also allow an adjustment of the cleaver.
  • the chopping knives are offset in the direction of the chopper rotor circumference and arranged distributed along the axis of rotation of the segments, so that only a cleaver is currently in hackeingriff. As a result, a successive and uniform cutting is achieved with less torque.
  • the chopping knives are parallel to the generatrix of the lateral surface of the chopping rotor and thus aligned at an angle to the axis of rotation and determine the direction of rotation of the chopping rotor. Due to the oblique position to the feed direction, the cleaver does not engage along the entire length of the cutting edge in the material to be shredded. This requires a lower torque.
  • the counter strip is designed as a counter-blade. This configuration ensures a particularly secure hold of the material to be comminuted between the cutting edge of the chopping knife and the counter-blade forming the counter-cutting edge.
  • the setting of an arrangement is possible in which a uniform gap is desired to produce wood chips of certain shape.
  • the conveying belt feeding the material to be comminuted is inclined at an angle to the axis of rotation of the chopping rotor.
  • the preferred inclination angle corresponds to the inclination of the generatrix of the cone of the chopping rotor to the axis of rotation of the chopping rotor.
  • a dividing screen extends from an edge below the counter ledge to the ceiling of the rotor space.
  • the dividing screen is formed of a thick sheet which can withstand larger forces such as e.g. can withstand the forces of the supplied crushed material.
  • the dividing screen allows chips corresponding to or smaller than the size of their openings, with the remaining chips remaining in the dividing screen until they are shredded to the desired size by the hacking rotor.
  • the separating screen thus also acts along its surface facing the chipping rotor as a counter-cutting edge.
  • the surface of the separating screen corresponds approximately to half the lateral surface of the chopping rotor.
  • the dividing screen has a conical shape. This shape is particularly preferable because it allows the separating wire to be evenly spaced from the chipping rotor.
  • the separating sieve with its surface facing the chipping rotor, also serves as a counter-cutting edge.
  • the fan is arranged below the chopping rotor.
  • the chips falling through the separating sieve are, without detour, passed directly from the disc of the fan by being thrown by the centrifugal force to the edge of the rotating fan disc, and are further promoted from there by an air flow generated by blades.
  • the blower is realized by means of a round disk attached to a drive axle, at the end of which radially pointing blades are mounted, which generate the air flow of the blower.
  • the comminution machine shown in FIG. 1 has a conical chipping rotor 4, which is accommodated in a rotor space 2.
  • a conical chipping rotor 4 which is accommodated in a rotor space 2.
  • two adjacent steel disks 1 are connected by a steel plate (not shown), which is aligned parallel to a surface of the generatrix of the conical chopping rotor, wherein the steel disks 1 at an equal distance along a Rotary axis 3 is arranged offset and connected thereto.
  • These connecting steel plates are used to attach the chopping knives 6.
  • the cleavers are arranged offset in the direction of the hackrotorwins. Likewise, the cleaver along the axis of rotation 4 are distributed to the segments, so that only a cleaver 4 is currently in hacking engagement.
  • a fan 12 of the crushing machine is arranged.
  • the fan 12 is composed of a drive shaft 30 and a disc 15 mounted thereon, wherein at the end of the disc 15 in the radial direction facing blades 16 are arranged.
  • the chopped material falling onto the disk is thrown outwards, the chopped material subsequently being conveyed further by the compressed air generated by the blades.
  • a screw conveyor was required for this purpose.
  • FIG. 2 shows a rear sectional view of a crushing machine.
  • the conical hack rotor 4 consisting of axis of rotation 3, segments 5, and the chopping knives 6 is shown.
  • a counter strip 20 which is parallel to the generatrix of the conical chopping rotor 4 and arranged below the axis of rotation 3 ist.
  • the counter-strip 20 serves as a counter-cutting edge for the chopping knives 6, which chop the comminution material brought up by a conveyor belt 8, 10.
  • a cutting edge 7 of the chopping blade 6 has the same distance from the counter strip 20 over its entire length.
  • the conveyor belt 8, which feeds comminution material to the comminuting machine, is inclined in the direction of the generatrix of the chopping rotor and has on its surface protrusions 11 which provide a return. and prevent slippage of the crushed material from the conveyor belt.
  • the inclined arrangement of the counter strip 20 and the conveyor belt 8 to the conically shaped chopping rotor determine the favorable hoe characteristics of the present invention.
  • the crushed material is slightly rotated during a chopping or cutting process and laterally on the Counter bar further pushed, thereby changing the orientation of the crushed material to the cutting surface constantly.
  • the cutting edges of the chopping knives are not arranged parallel to the axis of rotation of the chopping rotor. Consequently, the cutting edge does not strike the wood along its entire length at the same time. In this hacking process, therefore, the hacking process is more uniform, with the hacking rotor not requiring high torque.
  • the dividing screen 18 connects immediately below the counter bar 20 to this and is detachably connected to her. On the other hand, the dividing screen 18 is almost led up to half the circumference of the rotor and fixed to the housing of the rotor chamber 2.
  • the shredded material peeled off by the chopping blades 6 of the chopping rotor 4 is further chopped by the chopping rotor 4 until the chips have a dimension which is smaller than the diameter of the openings of the separating sieve 18.
  • the small wood chips go through the openings of the Trennsiebs 18 down.
