Definitions

  • the present invention relates to a Device for crushing and grinding coarse Material provided with a rotor with a number juxtaposed, essentially running all around Ribs and arranged over its surface Slots in which tool holders are arranged on which effective tools are attached in the direction of rotation of the rotor, which tools have a cutting surface that can be cut through straight side edges is limited, which Cut surfaces, together with that formed by the ribs Profile, with a toothed counter knife work together on which the rotor can rotate.
  • Such a device is known from EP-C-0 419 919 known.
  • the Tool holder attached to the rotor by welding, whereby if the tool is damaged and replaced the tool has to be ground out of the rotor.
  • the profile of the Ribs on the rotor essentially V-shaped and especially right-angled and work with the straight running side edges of the cutting surface of the tool with the straight teeth of the counter knife.
  • the gap between the rotor and the counter knife is hereby almost the same over the entire length of the rotor.
  • the object of the invention is to overcome these disadvantages at least to a significant extent and a Device as described in the introduction to create in the the material is passed through more easily and if, when in Using a tool will damage this evil quickly and can easily be fixed.
  • the device for Crushing and grinding coarse material characterized in that between that formed by the ribs Profile and the counter knife a gap of at least over Part of the length of the rotor varies in size and that the tool holder is releasable on the rotor are attached.
  • a gap of varying size can be easily obtained when the teeth of the Counter knife straight and the ribs a wave profile exhibit.
  • the ribs a straight profile and the teeth of the Counter knife to give a wave profile or both the teeth the counter knife and the ribs of the rotor to give different profile that there is a gap between the rotor and the counter knife in a varying size is obtained.
  • the tool holders are mentioned in EP-C-0 419 919 designed as a block and each of these tool holders is on two sides by welding in a V-shaped slot attached to the rotor.
  • the slots have another aspect the invention essentially in the form of a block-shaped Cut out and the tool holders are in it with bolts attached.
  • a tool holder needs to be replaced, Being able to loosen and remove it easily will be included used as a pin.
  • the latter measure is especially important when the tool is made of a harder one Material is made as the tool holder. Because straight then if the whole of tool and tool holder very large forces, a possible deformation Namely occur in the tool carrier, which causes this the rotor may get stuck in such a way that it it is difficult to remove the tool carrier.
  • both in front of the tool and in a certain distance behind the tool holder Cavity present. These cavities are special important if the tool is through a bolt-nut connection is attached to the tool holder, the bolt itself tangentially to the rotor through, one after the other, the tool, the Tool holder and an edge part of the Rotors extends. The cavity behind the tool holder is then almost directly behind the latter edge part of the rotor.
  • the cavity runs in front of the tool towards the tool more inwards and it ends above the lower straight angle of the Cutting surface of the tool.
  • the crushing device shown in FIG. 1 and grinding of coarse material comprises a frame 1 a filling shaft 2. Near the bottom there is a with Cutting or chopping tools, motorized driven rotor 3, which with a counter knife 4th cooperates. On a support plate 5 is a moving floor 6 in Movable back and forth in the direction of arrow 7. Also the Push floor 6 is motorized, in particular hydraulic driven and pushes the bottom layer of the in the filling shaft 2 introduced material 8 against the rotor 3. When the push floor 6 is pulled back, material falls down from the filling shaft 2 and it can again through the Pushing floor against the rotor. The crushed and ground material 9 falls out of the bottom Contraption.
  • the rotor 3 is side by side with a number attached all-round ribs 10, the one Have wave profile, and with helical above it Provided surface distributed slots 11.
  • the Slots 11 have the shape of a block-shaped recess 12 on, in which a provided with a tool 13 Tool holder 14 can be attached.
  • the tool is made of a harder material than that Tool carrier.
  • the tool holder 14 is by means of bolts 15 attached in a slot 11. Because when the device in Is operation on which tools are exerted great forces and the tool carrier made of a less hard material If the tool exists, there is a high risk of deformation occurs in the tool carrier and that this is so is stuck that he can hardly be removed if it should be necessary even if the bolt itself are started.
  • the bolt connection is therefore with Push pin executed.
  • a V-shaped Recess 16 available in which the tool 13 is attached is.
  • This tool 13 is block-shaped and is in Direction of rotation of the rotor on the front with cut surfaces and cut edges 17.
  • the tool 13 is on the Tool holder 14 fastened with the aid of a bolt 18 which tangent to the rotor from a cavity in the Front on the cut surfaces 17 through the tool 13, by the tool carrier 14 and by a collar part 19 of the Rotor, on which the tool carrier rests at the back, extends and at the back of this collar part 19 with Help a nut 20 is attached.
  • the rotor with the tools like this one above cooperates with the counter knife 4, which in Fig. 11 is shown.
  • the counter knife 4 is straight extending teeth 25 provided. These teeth 25 cooperate the shaft ribs 10 and the tool 13 together. Through the Shape of the ribs 10 and teeth 25 is in the longitudinal direction of the Rotor 3 obtained a gap 26 of varying sizes, whereby the material to be shredded and ground more easily is passed through.
  • the invention is not based on the here Drawing described embodiment limited, but includes all sorts of modifications, of course insofar as these fall within the scope of protection of the following Claims fall. So are all kinds of tools and of the cut surfaces and cut edges possible. They can also Teeth of the counter knife have a wave profile while the ribs just so straight that there is still a gap between the rotor and the counter knife of a varying Size is preserved.
