Definitions

  • the invention relates to the rotor of a crushing device of wood, waste or other material from between adjacent rotor disks to the rotor shaft coaxial rackets swinging and / or stationary arranged tools and other protective elements.
  • a disadvantage of this known embodiment of a crushing device is the need for the radial opening in the bearing eyes, which leads to a significant weakening of storage, as well as a weakening of the racket rod. Furthermore, this design is reserved for a shredder or impact rotor and can not be transferred to hoisting drums with stationary tools.
  • the object of the invention is to provide a rotor of a crushing device of wood, waste or other material available that ensures a robust storage of tools and protective elements and also universally and economically adapted to the required quality of a woodchip can be and also has an increased smoothness and increased reliability.
  • a protective element consists of a base body with at least two connecting means for attachment to the rotor, wherein the first connecting means of a completely closed bearing eye is formed for receiving the racket rod and the second connecting means of a coupling device which has in a mounted state of the main body with this mutually engaging latches.
  • the main body is thus not only equipped with a single closed bearing eye and already designed to be considerably more robust, but also with a further positive Verrieglung with the rotor discs, whereby the resistance of such a protective element against mechanical influences during operation of the crushing device is increased enormously.
  • the type and embodiment of the attachment of such a protective element is independent of the choice of tools to be arranged in the rotor, they are free swinging or fixed, so that can generate a variety of possible variants of a combination of tools and protective elements, even the combination of swinging and fixed arranged tools allows, as well as differently designed protective elements, with the help of which in particular the required quality of the wood chips can be influenced.
  • the positive locking of the protective element is designed as a claw-shaped receptacle on the base body, which is a rotor discs connecting connecting rod or other rotor-proof projections surrounds, said claw-shaped receptacle is preferably arranged in a direction of rotation of the rotor in the circumferential direction in front of the bearing eye of the main body fixing racket, so that for mounting initially the claw-shaped receptacle with its counterpart between the rotor discs are connected must, whereupon the protective element brought with its bearing eye in alignment with the receiving bushes of the rotor disks for a racket rod and then the racket rod can be driven together through the receiving bushes and the bearing eyes through.
  • a cover element is associated with the base body, which is embodied with it either as a one-piece cover body or which is detachably connected via connection means to a multi-part cover body with the base body.
  • a one-piece version of a cover body could for example be designed as a welded part, although such is very robust, but due to the required sheet thickness has a total weight, which is no longer easily handled by a single fitter.
  • a cover element detachably connected to the base element via connecting means allows a much simpler handling, since both components can be mounted one after the other, with further significant advantages occurring in this embodiment, such as initially only mounting the individual base bodies without the separate ones Covering the base rotor can be done and the cover only later, after inserting the rackets rods are fixed to the bodies.
  • the free cover elements can also be designed as pure wear parts, so that after the wear of these parts not the entire cover body, but only the cover must be replaced, thereby significantly improving the efficiency of the rotor according to the invention, especially for the replacement of the cover not the racket rods must be pulled out of the rotor, but the disassembly of the old and the installation of the new cover can be done immediately and easily on the rotor.
  • the releasably connected cover elements have a front-coupling device in the circumferential direction and a rear contact surface with the base body and there recesses for mutual connection means, wherein the rear contact surface with the base body in a radial direction offset from the peripheral surface of the rotor inwardly is angled, so that the connecting means designed as screws arranged quasi in the "shadow" of the tools and the effective covering surfaces of the cover of the rotor and are removed in operation from the region of high wear.
  • the front coupling device preferably also consists of a claw which engages around a rod coaxial to the rotor shaft of the body or other vigangee projections, so brought to their assembly, first the claw of the cover into engagement with the counterpart of the body and then the cover over its rear Contact surface can be fixed to the body.
  • the protective elements can be designed with different contours and / or different distance dimensions from their outwardly directed surfaces to the bearing eyes of the base body, so that at least for fixed standing tools of the rotor a defined anticipation of the tools can be set.
  • the rotor disks are equipped with axially projecting receiving bushes for the racket rods and the base body with receptacles that partially overlap the receiving bushes of the rotor disks, so that at least in an assembly or disassembly position with removed racket rod with its second coupling device engaged body with its recordings can rest on the receiving sockets, wherein the bearing eyes are approximately aligned with the receiving bushes of the racket rod, so that the recordings are lifted in the mounted state of a racket rod from the receiving sockets.
  • the rotor 1 of the comminution device consists of mutually offset rotor disks 2 or rotor part disks, which are welded together from around the circumference, coaxial with the rotor shaft 8 connecting rods 3. Furthermore, the rotor disks 2 are receiving bushes 15 extending in the direction of the respectively opposite rotor disk 2 for a racket rod 4 penetrating all rotor disks 2, the racket rods 4 having to be pulled axially out of the rotor 1 for mounting the tools 19 and the protective elements 7.
  • the tools 19 can be arranged swinging or fixedly mounted on the rotor 1, as well as the protective elements, which consist at least of a base body 5, which consists essentially of a parallel arranged centrally between the rotor disks 2 plate, with a welded receptacle 16 with a bearing eye 9, and in its circumferentially front portion of a claw-shaped receptacle 10 of two parallel plates with a U-shaped recess, as shown in the Fig. 1, 2 and 6 is clearly visible.
  • a base body 5 which consists essentially of a parallel arranged centrally between the rotor disks 2 plate, with a welded receptacle 16 with a bearing eye 9, and in its circumferentially front portion of a claw-shaped receptacle 10 of two parallel plates with a U-shaped recess, as shown in the Fig. 1, 2 and 6 is clearly visible.
  • the protective element of the base body 5 is provided with an additional cover 6, which has a claw 12 at its front in the rotational direction of the region, which is an axial arranged transverse rod 13 between the two sheets of the U-shaped claw-shaped receptacle 10 of the base body 5 can engage and which has in its end a rear contact surface 14 which has corresponding recesses 11 with a just such contact surface of the body 5 for connecting means formed as screws.
  • This end region of the cover element 6 is angled inward in a radial direction from a circumferential direction of the rotor 1 and thus removed from the active protection region of the cover body 7, so that the connecting elements do not experience any mechanical wear.
  • the cover element 6 On its inner side facing the main body 5, the cover element 6 is equipped with two additional reinforcing ribs 17, which extend laterally of the plate of the main body 5 parallel to the rotor disks 2.
  • the bearing eye 9 of the receptacle 16 of the base body 5 is aligned in the partially assembled state of the protective element with not yet introduced club rod 4 approximately in alignment with the receiving sockets 15 for the racket bar 4, wherein upon insertion of the claw-shaped receptacle 10 of the main body 5 on the connecting rod. 3 of the rotor 1 and lowering the rear part of the main body 5 on the rotor 1, the receptacle 16 on the receiving bushes 15 comes to rest and the bearing eye 9 remains in the position described, thereby facilitating the subsequent insertion of the racket rod 4.
