Definitions

  • the invention relates to an on the working cylinder of a crushing device for compostable material, in particular for plant waste together with waste from waste wood, such as pallets, lumber and the like materials, arranged cutting plate.
  • the invention further relates to a stocked with a variety of these tools working cylinder such crushing device.
  • Crushing devices of this type are known in different embodiments. They have working cylinders, also referred to as rotors or rollers, are arranged on the lateral surfaces radially outwardly directed cleaver, teeth, thorns, spikes or other work tools that rotate with the working cylinder while the material to be crushed, the Working cylinder is supplied, crush in cooperation with relatively stationary counter-tools.
  • working cylinders also referred to as rotors or rollers
  • These tools are provided with cutting or cutting-like bevels, which act on the material by virtue of the torque generated by the rotation.
  • These tools are known, which are designed for rigid attachment to the lateral surface of the working cylinder and provided with cutting, which always point in the direction of rotation due to the predetermined orientation on the working cylinder. As a result, during operation of the device, they are constantly in engagement with the material and are subject to wear.
  • Another, flail-trained working tool for waste crushing of compostable material describes the utility model DE 92 03 651 U1 , This tool is also provided for rigid attachment to the outer surface of a working cylinder and equipped with cutting, which also always have in the direction of rotation.
  • Crushing device must be removed, which in particular then unwanted downtime has the consequence, if it is a mobile crushing device and the regrinding must be made in a remote from the site workshop.
  • the cutting plate is geometrically designed so that it in the direction of rotation of the working cylinder as well as opposite convex curved areas and in the vertical dimension are limited by plane-parallel opposing surfaces.
  • the cutting edges are respectively formed at the convex portions and at the transitions from the convex portions to the plane surfaces.
  • each two cutting plates relative to a normal of the lateral surface, symmetrically opposite, wherein the axes of symmetry of both cutting plates with the normal each include the angle ⁇ .
  • the angle ⁇ in a particularly preferred embodiment of the invention is 45 °.
  • the two cutting plates are releasably secured by a common clamping element of a clamping unit on the cylinder.
  • the attachment is designed such that the clamping element and both symmetrically opposed cutting plates below With the aid of hand tools from the cylinder can be solved and the inserts after rotation by 180 ° to the normal of the lateral surface again by means of clamping element and hand tools with the working cylinder are connected, after which the effective directions of cutting both cutting plates - with respect to the rotational direction of the working cylinder - are reversed.
  • Each clamping unit consists essentially of a support wedge, a clamping element and a screw connection.
  • the support wedge and the clamping element are worked so that, as already described above, two inserts / primary cutting tools can be releasably secured in a clamping unit.
  • the clamping unit itself is preferably accommodated in a recess in the lateral surface of the working cylinder, wherein the recess is designed groove-shaped, is arranged axially parallel to the axis of rotation in the lateral surface of the working cylinder and extends from the one end side to the other end face of the working cylinder.
  • Fig. 1a If the cutting insert 1 according to the invention is shown in a top view, Fig. 1b shows the side view.
  • the cutting plate 1 is provided in a section A1 with cutting S, which are formed on convex surfaces and which face, with respect to an axis of symmetry SA, mirror-symmetrical.
  • the cutting S are partly wavy, partly jagged shaped.
  • Fig. 1b From the side view Fig. 1b can be seen that the cutting plate 1 in the section A1, the shape of a plate is limited by plane-parallel surfaces.
  • the synopsis of Fig. 3a and Fig. 3b shows that the blades S are basically formed where the convex portions meet the plan boundary surfaces.
  • a second portion A2 of the cutting plate 1 is for attachment to the working cylinder 2 of a crushing device for Compostable material formed by clamping elements 3 and has for this purpose approaches 4 and 5, of which the approach 4 for determining the position and the approach 5 for stable alignment of the cutting plate 1 on the working cylinder 2 of the crushing device is used.
  • the way this attachment is in Fig. 2a to Fig. 2b clarified.
  • Fig. 2a is an example of the arrangement of two inserts 1.1 and 1.2 shown on the working cylinder 2, namely in a view facing the direction of rotation R of the working cylinder 2.
  • the axes of symmetry SA with a normal of the lateral surface. 6 of the working cylinder 2 each include an angle ⁇ in the value range 0 ° ⁇ ⁇ ⁇ 90.
  • the angle ⁇ on both sides of the normal is in each case 45 °, so that the inserts 1.1 and 1.2 are inclined in opposite directions.
  • the normal N, the axes of symmetry SA of the two inserts 1.1 and 1.2 and the axis of rotation 8 of the working cylinder 2 lie in the plane of the drawing, which is also cutting plane through this arrangement.
  • Fig. 2a shows a side view of it, in which the rotation direction R lies in the plane of the drawing.
  • Fig. 2c gives out the arrangement Fig. 2a in a top view again.
  • a common clamping element 3 is provided which is connected by means of a screw connection 7 with the working cylinder 2.
  • Each of the inserts 1.1, 1.2 rests on a support wedge 9, which defines the angle ⁇ .
  • the attachment with this clamping unit is designed such that the clamping element 3 and both inserts 1.1 and 1.2 are removable by loosening the screw 7 by means of hand tools from the working cylinder 2. After loosening the two inserts 1.1 and 1.2 are rotated by 180 ° to the normal N and again secured with the help of the hand tool on the cylinder 2.
  • the normal N, the symmetry axes SA and the axis of rotation 8 are visible in the sectional plane.
  • cutting inserts 1.1 or 1.2 inclined in an individual position may also be provided at an angle ⁇ to a normal N.
  • Fig. 3b shows the working cylinder after Fig. 3a in a side view looking in the direction of its axis of rotation. 8
  • Fig. 4b shows the stocked in the manner described above with primary cutting tools 6 working cylinder 5 in a side view looking in the direction of the rotation axis 12.
  • the primary cutting tools 6 are arranged for example on four generatrices, which are offset by 90 ° in the direction of rotation R.
  • run-on wedges 23 and discharge wedges 24 for the material 3 can be provided in order to further increase the efficiency of the comminution.
  • the Fig. 7 shows a schematic representation of the occupancy of this working cylinder 2 'with the inserts 1'.
  • the blackened bars each symbolize a primary cutting tool, here an insert 1 '.
  • the secondary cutting tools are to be arranged on the secondary cutting tool carrier of a crushing device.
  • the choice of the respective position scheme remains reserved to the user. It is important and part of the invention that the user is given the opportunity for the first time either to choose himself or to commission the manufacturer according to his choice, that the arrangement of the primary cutting tools and the secondary cutting tools can be more specifically addressed to his requirements in the operation of the crushing device , Depending on whether the shredded material is to be coarser or finer grain, or which materials are to be comminuted with the crushing device, the user will choose his choice concerning the positional scheme of the cutting tools.
  • the distance L1 between the leading cutting edges of the paired cutting inserts 1 ' is greater than the distance between the trailing in the direction of rotation cutting edges of the respective pair of inserts 1', this detail 5d.
  • another clearance angle FW2 is created, which between the cutting edge SN and a sagittal plane of the clamping unit 25 is located.
  • a cutting plate 1 'of the second kind is shown in detail.
  • Compostable material in the context of the invention are green waste, wood packaging, wood waste, demolition wood, waste wood, fresh wood, bark, industrial wood waste and compost in the various rotting stages.
