Definitions

  • the invention relates to a chopping and shredding machine, in particular for use in the garden for shredding material intended for composting.
  • EP-A-0 253 232 describes a shredding device for plant remains.
  • This known device has a pick-up device for introducing easy-to-shred material, such as thin branches, leaves and the like, and a separate branch pick-up device for branches, stems or other stiffer material.
  • the length of the housing of the shredder is designed so that there is no chance of reaching a pre-cutting tool when it engages. However, this results in an unfavorable working height for the operator, which in turn leads to unnecessary work.
  • the present invention provides a chopping and shredding machine which has essentially no additional parts compared to a simple chopping or shredding machine and is therefore not larger or heavier than such a machine.
  • a feed hopper angled in the feed path for thick and round materials will be provided, with a small part of the working chamber of the machine overlapping with the inlet opening of the feed hopper in such a way that a straight feed path with a small cross section for branches or the like is bulky at this point Material arises.
  • FIGS. 1 to 3 A chopping and shredding machine 10 according to the invention is shown in FIGS. 1 to 3. It consists of a cylindrical comminution chamber 12 in which a set of knives 14 is fastened directly above the bottom of the chamber to a shaft 16 which passes through the bottom of the chamber and is connected to a drive motor 18 there.
  • the drive motor 18 is an electric motor, since the direction of rotation is easier to switch.
  • An electrical switching device is attached to the motor, which has the usual on and off switch with safety shutdown when the comminution chamber is opened. It is designated here by reference numeral 20 and additionally contains a switch for reversing the direction of rotation of the drive motor 18.
  • the machine can also be driven by an internal combustion engine. Then a reversing gear would have to be provided instead of the switching device.
  • the entire chopping and shredding machine is attached to a normal chassis 22, as is customary for such machines.
  • the comminution chamber 12 On the side opposite the electrical switching device 20, the comminution chamber 12 has an opening directly above the floor through which the comminuted material enters the outlet funnel 24 which is inclined downwards and via which it leaves the machine.
  • the width of the opening and the outlet funnel corresponds to the width of the comminution chamber 12.
  • the receiving funnel 26 is located on the comminution chamber, which is open at the top. This extends on the side of the electrical switching device approximately by the diameter of the comminution chamber 12 beyond the comminution chamber.
  • the receiving funnel is essentially open at the top in the region extending beyond the comminution chamber 12, while it is almost completely closed above the comminution chamber.
  • the receiving funnel 26 forms a receiving opening 28 through which the material to be comminuted can be fed.
  • the funnel has two openings to the comminution chamber. A small opening 30 is located in the area in which the receiving opening 28 overlaps with the comminution chamber 12 when viewed from above.
  • This opening 30 can be provided with a non-return flap 32, through which the comminuted material can be prevented from being thrown out through this opening.
  • a guide plate 34 is provided on the small opening 30, which protrudes into the comminution chamber 12 in such a way that a guide channel for guiding the material to be comminuted through the opening 30 is formed through this plate and the wall of the comminution chamber 12.
  • the opening has the shape of a ring segment, the inner radius of the ring being larger than the radius that the pre-shredder 40 sweeps over.
  • the guide plate 34 is fastened to the inner edge of the opening. It therefore has the shape of a segment of a circle.
  • the receiving funnel 26 has a further larger opening 36 in the direction of the comminution chamber 12.
  • This opening 36 is also closed with a non-return flap 38 in order to prevent comminuted material from being thrown out. It is at right angles to the direction of entry of the receiving opening 28 and thus forms a twice angled passage into the comminution chamber. According to the safety standards, a passage of 250 mm is provided for this opening.
  • the knife set 14 consists of a pre-shredder 40 rotating above the opening of the outlet funnel 24 and a shredding disk 42 which is attached at the level of the opening of the outlet funnel 24.
  • the entire set of knives 14 rotates about the central axis of the cylindrical shape of the comminution chamber 12.
  • the pre-shredder 40 is only used in the chop operation. It consists of a metal strip bent open in the end sections. The two working edges 44 of the pre-shredder are at the top right and bottom left. The end sections of the pre-shredder are chamfered on the back to create a clearance angle for the working edges.
  • the comminution disk 42 has two slots 46, which are each provided for the passage of the comminuted material and are each delimited on one side by a knife.
  • An impact knife 48 of the shredding disk 42 is fastened in such a way that it acts counterclockwise when viewed in a direction of rotation from above.
  • a cutting knife 50 is fixed so that it is in the reverse direction comes into effect. Then at the bottom of the shredding disk 42 are still cleaning plates 54 which extend almost to the bottom of the shredding chamber 12.
  • the comminution chamber 12 also contains a wedge 52 mounted above the comminution disk.
  • the position of this wedge 52 is indicated by a chain line in FIG. 1, since the position of this wedge would normally not be discernible in the section of FIG. 1, since it is on the cut-away side belongs.
  • the wedge has an edge which runs radially to the comminution disk 42 and which extends perpendicularly to the upper edge of the comminution chamber 12. This edge has the same width over the entire course. On the side opposite the edge, the wedge runs at an acute angle along the curved wall of the comminution chamber 12.
  • the wedge 52 is increasingly shortened towards the top, so that the wedge angle becomes increasingly blunt towards the top.
  • the knife set 14 runs counterclockwise when viewed from above in accordance with the arrow denoted by H in FIG. 2.
  • the material to be chopped is filled by an operator through the receiving opening 28 of the receiving funnel 26. It goes through the openings 30 and 36 into the comminution chamber 12. Very large pieces such as cabbage heads, beets and the like naturally only pass through the opening 36.
  • the wedge 52 has the effect that the material located in the comminution chamber not only rotates at the rotational speed of the knife set, but also receives a lateral movement relative to the knives, since the wedge 52 removes the material to be chopped Presses well against the pre-shredder 40.
  • the pre-comminuted material then passes through the slots 46 under the comminution disk 42. In the process, it is further comminuted by the impact knife 48. Finally, the comminuted material is conveyed through the clearing plates 54 into the outlet funnel 24 and leaves the machine through this.
  • the schnitzel operation is used to shred bulky, woody goods, such as Tree branches and the like.
  • the knife set 14 rotates clockwise in accordance with the arrow labeled S in FIG. 2. Since the bulky material cannot enter through the multiple-angled feed opening 36, it is only through the straight passage through the receiving opening 28 that small opening 30 and the guide channel formed by the guide plate 34 is limited. As a result, the bulky material passes the pre-shredder directly to the shredding disk 42.
  • the cutting knife 50 of the shredding disk 42 comes into effect in the direction of rotation for the shredding operation. It cooperates in a particularly advantageous manner with the radial edge of the wedge 52.
  • a knife bar or a polygonal plate for example in a triangular shape, can also be used.
  • the percussion and cutting knives must then also be attached to these knife carriers in the associated direction of rotation.
