  • the funnel Due to the displaceability of the funnel with respect to the housing, the funnel can be moved in a particularly simple manner relative to the housing from the first position to the second position. Likewise, the funnel can be pushed back into the first position in a particularly simple manner.
  • the funnel can be moved by controlling the pusher.
  • the coupling allows the drive of the pusher to combine both the pusher and the hopper. This results in a particularly simple and compact design for the device.
  • the coupling can be done manually by a coupling member, such as a connector.
  • a coupling member can be hooked on the post-presser and / or on the funnel. It may also be possible to perform an electromagnetic or a hydraulic coupling.
  • As the pusher moves to the second position that is, as the pusher moves away from the rotor and counter knife, it can thus efficiently move the funnel.
  • the funnels and push-pulls typically move in the same direction.
  • one or more guide grooves or rails may be provided on the housing for guiding the hopper.
  • the guide rails or guide grooves on the housing make it possible to move the funnel so that it is displaced guided on the housing.
  • the movement of the funnel from the first position to the second position can be defined particularly well.
  • the funnel can be additionally secured, for example, via the guide rails, so that it can not come loose from the housing, ie from the housing surface, during the movement.
  • a drive for moving the hopper may be provided, wherein the drive may be designed as a linear drive.
  • the movement of the funnel can advantageously be done by a drive. Since the mass of the funnel can be large as a rule, a drive as precise as possible movement of the funnel relative to the housing can be ensured. This can be done in particular by a linear drive. Thereby, the translational movement of the funnel can be ensured from the first position to the second position according to a predetermined course.
  • the drive can be designed mechanically and / or pneumatically and / or hydraulically and / or as a chain drive.
  • drives such as a mechanical and / or pneumatic and / or hydraulic drive and / or chain drive.
  • these types of drives can also be combined.
  • the pusher can be coupled to the hopper in the first position.
  • the coupling can be advantageously carried out in the first position.
  • the pusher usually operates during the normal crushing operation of the crusher independently of the hopper.
  • the pusher can be moved to a position where the head of the pusher is close to the rotor and the counter knives, ie the pusher is moved far or even maximally in the direction of the rotor, for example extended .
  • Coupling the pusher with the hopper which is in the first position already defined above, can ensure that the pusher has a particularly large stroke to move the hopper as the pusher moves to the second position.
  • the pusher may be provided so as to remain completely in the casing during the crushing operation.
  • the crushing device can be made particularly compact.
  • the comminution device can be a single-shaft shredder with stationary counter-blades or counter-blades or a multi-shaft shredder with counter-blades or counter-blades arranged on a further rotor.
  • the comminution device can therefore comprise various common types of single-shaft or multi-shaft shredders and can thus be adapted to different usage requirements.
  • the FIG. 1 shows a crushing device 100 according to the invention.
  • the crushing device 100 comprises a housing 101, a rotor 103 and at least one counter blade 105.
  • the or the counter blade 105 may / may be attached, for example, to a block-like counter-element unit 105b. It is understood that more than one counter-blade 105 can be used.
  • Material to be comminuted for example plastic, is received in the comminuting device 100 through a funnel 109 and fed therefrom to the rotor 103 and the at least one counterblade 105.
  • the material can for example be moved out of the hopper 109 in the direction of the rotor 103 by the gravitational force acting on the material.
  • the funnel 109 is located in FIG. 1 on the housing 101.
  • a suitable opening 119 is provided, through which the material from the hopper 109 can get into the interior 101a of the housing.
  • the material is then comminuted by cooperation of the rotor 103 and the at least one counter knife 105.
  • the area in which the rotor 103 and the counter knife or knives 105 cooperate and crush the material may also be referred to as the working area or comminution area of the comminution device 100.
  • the shredded material may be dispensed through a screen 111 and collected outside the shredder 100 and removed, such as to be recycled.
  • the FIG. 1 also shows a push button 107.
  • the push button is provided in the housing 101 of the comminution device 100.
  • the pusher 107 is movable so that he pushes the material to be crushed in the direction of the rotor 103 and the or the counter blade 105. The material to be shredded is thus pressed by the pusher 107 toward or into the work area. This significantly increases the efficiency of the comminution process.
  • FIG. 1 a hydraulic drive 107a, 107b and 107c of the post-presser 107 are shown.
  • the reference numeral 107a denotes a Nachdrücker piston.
