Definitions

  • the present invention relates to a device for comminuting objects, in particular organic waste, waste wood, plastics or the like.
  • a device for comminuting objects in particular organic waste, waste wood, plastics or the like.
  • an inlet and an outlet and at least one rotor element mounted in a housing, which is driven or driven on a shaft, the rotor element being one
  • a plurality of tool elements, in particular cutting elements, is assigned.
  • Such devices are known and available in a wide variety of forms and designs on the market. They are primarily used to shred waste wood, branches, twigs, organic waste and the like. Since nowadays organic waste, in particular waste wood for composting, further processing or removal, has to be shredded more and more, the demands on such devices are increasing. Such devices are said to be very light.
  • a disadvantage of the conventional devices is that their tools, in particular cutting elements, wear out very frequently, especially when very hard objects have to be shredded. Such cutting elements are often also damaged. Rotor elements or cutting elements often have to be overhauled and replaced, which is expensive and undesirable.
  • a further disadvantage is that organic waste, in particular also waste wood, does not always run optimally into the rotor element.
  • the present invention has for its object a generic device of the above. To create a way that eliminates the disadvantages mentioned.
  • the service life of the tools is to be increased considerably, and the cutting of organic waste, waste wood and the like is also to be improved.
  • the feeding of organic waste and waste wood into the rotor element is to be optimized.
  • At least one shear bar is provided near the tool element approximately axially parallel to the shaft.
  • the present invention allows a first, second, and possibly a further comminution to be possible in the case of an arrangement of several counter cutting edges.
  • a shear bar between the transport element, in particular endless conveyor, and the rotor element. This is arranged at an angle to the rotor element. Furthermore, it is arranged slightly downwards to a center point. This ensures that the waste wood gets into the Rotor element is drawn. Much higher amounts of waste wood can be processed in a short time.
  • the counter cutting edges are slidably mounted within openings in side walls. These are pressurized with spring elements and are preferably pressurized against an upper stop edge. If very hard objects are introduced into the rotor element for shredding on the shear bar, the shear bar can move downwards.
  • the setting of the energy accumulator and its spring constant can influence the damping behavior of the counter cutting edges.
  • a screen element is at least partially provided between two opposing cutting edges, which are also resiliently mounted in openings in the side walls of the housing.
  • This sieve element is provided with a plurality of sieve openings in order to discharge the comminuted fraction. Those particles that do not fit through the corresponding openings in the sieve element are transported further to a further size reduction stage and from there are transported back into the inlet area. There they have to go through the first shear bar between the transport element and the rotor element and can go through further stages again in this way.
  • the tool elements in particular cutting elements, are arranged offset to one another on the rotor element and the cutting platelets are arranged interchangeably on corresponding holders, not shown here. These can then be quickly replaced individually.
  • the counter cutting edges in elongated openings. They can be subjected to pressure from a lower stop edge by means of the energy accumulator against an upper stop edge.
  • the opening is rectangular in shape in accordance with the shape of the shear bar and always guides the shear bar in its longitudinal direction.
  • the present inventive concept is also intended to include the fact that the energy stores, in particular spring elements, can be arranged interchangeably outside the side wall of the housing.
  • the present invention provides a device for comminuting objects, which optimizes the shrinking process, the device running overall more smoothly and the service life of all tools being considerably increased by damping and resilience of the shear bar.
  • a device R according to the invention for comminuting objects, organic waste, waste wood, plastics and the like has a housing 1 which is provided with an inlet 2 for supplying waste, in particular waste wood.
  • the device R is preferably movably arranged on a trailer 4 so that it can be transported.
  • the material to be shredded passes through the inlet 2 into the interior of the housing 1 to a rotor element 5 which is driven or driven on a shaft 6, see FIG. 2.
  • the rotor element 5 is provided with a plurality of cutting elements 7, which are preferably fixed to the rotor element 5 in a chisel-like and exchangeable manner on corresponding holders, not shown here are. These are preferably arranged offset to one another on the rotor element 5, as is shown, for example, in FIG. 3.
  • the material comminuted in the device R reaches an endless conveyor 9, in particular a conveyor belt, in order to separate the comminuted fraction from the device R. This will be dealt with in more detail.
  • the device R is equipped with a plurality of drive elements, drive motors, controls and the like, not numbered here, in order to drive the corresponding rotor element 5 at a desired speed.
  • the rotor element 5 sits between two side walls 10.1, 10.2, as is also indicated in FIG. 3, wherein it is rotatably mounted. So that a comminution of organic waste is possible at all, three counter cutting edges 11.1 to 11.3 are provided in the present and preferred exemplary embodiment according to FIG.
  • the counter cutting edges 11.1 to 11.3 are arranged near the tool elements 7, in particular cutting elements, axially parallel to the shaft 6.
  • the shearbar 11.1 to 11.3 has the task of producing a shearing effect between the tool element 7, in particular the cutting element or other comminution element and a shear edge 12. The material is shredded by shearing.
  • the counter cutting edges 11.1 to 11.3 are mounted in openings 13.1 to 13.3 of the housing 1, in particular in side walls 10.1, 10.2.
  • the opening 13.1 to 13.3 is preferably elongated and rectangular, in which the shearbar 11.1 to 11.3 is resiliently mounted.
  • the shear bar is slidably guided and stored in the opening 13.1 to 13.3.
  • the shearbar 11.1 to 11.3 counter to one Direction of rotation X see Fig. 2, is resiliently pressurized.
  • energy accumulators 14 are provided, which are supported on the housing 1, in particular on the side walls 10.1, 10.2, and apply pressure to the counter cutting edges 11.1 to 11.3 against an upper stop edge 15 of the opening 13.1 to 13.3.
  • the energy accumulator 14, in particular the spring element can be supported outside the side wall 10.1, 10.2, or can be located within the opening 13.1 to 13.3, as is shown in particular in FIG. 3.
  • the present inventive concept is also intended to include the fact that the energy accumulator 14 is supported on a lower stop edge 16.
  • the energy accumulator 14 is preferably a spring element here. However, it can also be hydraulic, pneumatic or electromechanical. In particular, a hydraulic spring with an automatic, controllable and changeable parameter during operation is also contemplated.
  • the counter cutting edges 11.1, 11.3 are arranged in opposite openings 13.1 to 13.3, with the rotor element 5 lying between them.
  • the counter cutting edges 11.1, 11.3 are spaced close to the tool elements 7.
  • the stop edges 15 of the openings 13.1, 13.3 preferably lie in a plane E which runs through a center M 1 of the shaft 6.
  • the spring elements 14 apply pressure to the counter cutting edges 11.1, 11.3, so that they are subjected to pressure on the stop edge 15 against the direction of rotation X of the rotor element 5.
  • a small gap S is formed. If a very hard object hits the shearbar 11.1 to 11.3, it can yield through the energy store 14. The gap S is enlarged.
  • a further special feature of the present invention is that the shearbar 11.2 is arranged between the transport element 3 and the rotor element 5.
  • the advantage here is that this shear bar 11.2 and its elongated opening 13.2 are arranged vertically.
  • the stop edge 15 is formed from the side wall 10.1, 10.2.
  • the counter cutting edge 11.2 is preferably spaced downwards at a distance A from the center M 1 of the shaft 5. Furthermore, the shear bar 11.2 and its opening 13.2 are arranged parallel to the plane E. An angle ⁇ is formed between a tangent ⁇ , the rotor element 5 and the shearbar 11.2. This angle ⁇ results in easy adjustment of the tool elements 7 with respect to the shearbar 11.2. This increases the pulling in of material to be shredded, which is conveyed through the inlet 2 into the housing 1 via the transport element 3.
  • the first shredding takes place at the shear bar 11.2.
  • the roughly comminuted fraction is then conveyed by rotating the rotor element 5 in the direction of rotation X to the second shear bar 11.3 and further comminuted there.
  • a bulkhead 17 prevents the chips from escaping.
  • the rotation of the rotor element 5 brings the comminuted material into a region between the bedknife 11.3 and 11.1. In this area, the rotor element 5 is surrounded by a sieve element 18.
  • a plurality of sieve openings 19 are provided in the sieve element 18, as are also shown in FIG. 4.
