Definitions

  • the two rotary shafts are arranged horizontally in a chamber in the form of a vertical duct, the materials being introduced from above onto the two shafts and discharging downwards once shredded.
  • the feeding and evacuation are done automatically by gravity, which ensures simple and safe operation.
  • the materials to be shredded may contain specially hard parts which cannot be crushed or pass between the trees and which is difficult to evacuate from the chamber.
  • the invention relates to a shredder of the type mentioned above, characterized in that the guide wall comprises a sliding shutter, disposed opposite the lower shaft and sliding along a path in an arc of a circle which is concentric with this shaft, this component comprising shutter baffles between which pass the shredding members mounted on the lower shaft.
  • the shredder comprises a hydraulic mechanism for opening and closing the sliding shutter, said mechanism being arranged outside the chamber. It further comprises a mechanism for locking the sliding shutter in the closed position, this mechanism preferably being provided with a hydraulic control.
  • the sliding shutter may comprise, along its upper edge, a deflector arranged outside the chamber and arranged to guide the materials which escape therefrom out of this chamber.
  • the respective axes 5a and 6a of the two rotary shafts 5 and 6 are offset both vertically and horizontally relative to one another.
  • the upper shaft 5 extends in the upper part of the chamber 2, while the lower shaft 6 is arranged below the shaft 5, in a position such that its axis 6a is substantially in a vertical plane 10 which is tangent to the peripheral surface of the upper shaft 5.
  • cover plates 34 and 35 which close off the parts of the slides 30 which are exposed, respectively in the closed position and the open position of the flap in order to prevent products enter it.
  • the upper flap 21 is constituted by an upper shaft 40, a thick anterior plate 41 supported by stiffeners 42 and a support plate 43 welded along the lower edge of the anterior plate 41.
  • the upper shaft 40 is pivotally mounted in the front walls of the body 1 of the shredder.
  • the upper flap 21 When the lower flap 20 is in the closed position, the upper flap 21 is kept in the closed position because its support plate 43 is applied against the deflector 26 by the weight of the flap and of the materials located in the chamber 2.
  • the lower flap 20 when the lower flap 20 is open, it is also possible to open the upper flap 21 by pivoting it on its shaft 40 to bring it into its open position drawn in broken lines and designated by 21a.
  • the upper shaft 40 of the upper flap 21 is mounted in a pivot in each of the front faces of the body 1 and it is secured, outside this body, of a lever 53 on which the piston rod of a hydraulic cylinder 54 which makes it possible to pivot the upper flap in one direction and in the other.
  • An identical cylinder can be provided at the other end of the shredder.
  • fig. 3 shows the end of a hydraulic cylinder 55 for controlling the locking mechanism of the lower flap. This mechanism is shown in more detail in FIG. 4.
  • the support 57 of this mechanism is fixed to the front wall of the body 1 of the shredder in a position corresponding to the position of the orifice 33 when the lower flap 20 occupies its closed position.
  • the latch 56 is advanced in the orifice 33 until the latch is locked in position by the bevelled faces of the latch 56. The latter then supports most of the transverse forces exerted on the lower flap 20 and partly on the upper flap 21 during the operation of the shredder.
