Definitions

  • the invention relates to an impact crusher with a rotor and at least two to one adjustable impact system connected to each other, a first, upper impact mechanism by at least a first drive around a first horizontal axis pivotable and on a second horizontal axis of the first, upper impact mechanism further, lower, pivotable by at least one second drive Impact device is arranged and wherein the first drive, the first, upper impact device as well the second drive supports the second, lower impact mechanism on the impact crusher housing.
  • each impact mechanism is supported individually adjustable on the housing of the impact crusher via a first or second drive, the respective drive consisting of at least one adjusting rod equipped with a thread, the position of which with respect to the housing can be changed manually by means of a nut interacting with the thread can and which is also resiliently held on the housing by springs in both directions.
  • the known impact crusher has the major disadvantage that the first, upper impact mechanism arranged behind the machine inlet diverts to the outside under the action of non-comminutable foreign bodies, as a result of which the grinding gap between the rotor and the second, lower impact mechanism is reduced; Accordingly, there is a risk that the foreign bodies get jammed here, as a result of which damage can occur to the rotor and / or to the second, lower impact mechanism, and the functionality of the impact crusher is no longer guaranteed.
  • the document DE-U-9305840 also discloses an impact crusher with a rotor and a first, upper impact mechanism, which is combined with an articulated second, lower impact mechanism to form an adjustable impact mechanism system, the first, upper impact mechanism being pivotable on the housing about a first horizontal axis of the impact crusher is held and the second, lower impact mechanism is movably connected to the first, upper impact mechanism via a second horizontal axis.
  • the latter carries at least one drive in the form of a cylinder, the piston rod of which is connected to a lever of the second, lower impact mechanism; each lever is arranged in the extension of the second, lower impact mechanism on the opposite side of the second horizontal axis so that it can be pivoted by the cylinder acting in a pivot point.
  • the second, lower impact mechanism can be moved between a folded open position and a working position pivoted in the direction of the rotor by retracting or extending the cylinder.
  • the second, lower impact mechanism In this working position, the second, lower impact mechanism is locked on its side facing away from the second horizontal axis by means of an adjusting device with the housing of the impact crusher, the position of said impact mechanism with respect to the rotor being able to be changed manually by actuating adjusting screws.
  • the second, lower impact mechanism Under the action of the at least one cylinder, the second, lower impact mechanism can be pivoted with respect to the first, upper impact mechanism in the manner mentioned.
  • the disadvantage of this known impact crusher is in particular that the second, lower impact mechanism cannot automatically perform a suitable evasive movement with respect to the rotor in the locked working position. Accordingly, damage caused by foreign bodies that cannot be shredded cannot be ruled out.
  • the invention has for its object a impact crusher of the aforementioned To further develop the genus in such a way that foreign bodies entering it that cannot be comminuted cannot cause damage.
  • An essential feature of the invention is that, due to the special arrangement of the point of application for the support and the articulation point on the at least one lever of the second, lower impact device, the grinding gap between the latter and the rotor in the event of an evasive movement of the first, upper impact device due to the influence of foreign bodies is enlarged.
  • This is made possible in particular by the fact that the second, lower impact mechanism is also supported on the housing of the impact crusher via at least one drive in the form of a cylinder.
  • the impact crusher according to the invention has, because of the advantageous arrangement of the point of application for supporting the second, lower impact mechanism, a particularly high level of functional reliability and thus a particularly long service life.
  • the subject of the invention arises not only from the subject of the individual claims, but also from the combination of the individual claims with one another.
  • the impact crusher has a hinged about a pivot axis 8 for opening Housing part 9 with a rotatably drivable rotor 10, which in the drawing Crushing elements, not shown, is equipped.
  • the first, upper impact mechanism 1 located above the second, lower impact mechanism 4 is pivotably mounted about a first horizontal axis 2 by at least one cylinder 3, which engages in an articulation point 3a, or another drive element.
  • a second horizontal axis 6 with the second, lower impact mechanism 4 - which is also referred to as a grinding track - is arranged so as to be pivotable.
  • the second, lower impact mechanism 4 has at least one lever 4a, on each of which a cylinder 5 or another drive element acts in the respective articulation point 5a.
  • a grinding gap 7 is formed by the second, lower impact mechanism 4 and the rotor 10.
  • the crushed material entering the impact crusher in the direction of arrow 12 is in the upper region of the impact crusher and broken through the first, upper impact mechanism 1 crushed and finally through the second, lower impact device 4 in the grinding gap 7 on the predetermined grain size ground.
