Definitions

  • the invention relates to a flail for a crushing device with a rotor, on or on which the flail is fastened, consisting of a frusto-conical lower body for connecting the flail to the rotor and at least one cutting body.
  • Such flails are known. They are used in crushing devices, which serve the crushing of material to be shredded.
  • a beater is known from the prior art, which is fixed circumferentially limited rotatably on a cylindrical base body.
  • the flail has a bearing body with a bearing bore and is rotatably supported by a bearing pin.
  • the bolt is designed even for a screw.
  • the bearing body is divided into two by a directed transversely to the bearing bore adjustment.
  • the two bearing body parts extending in the direction of the bearing bore Breakthroughs to dissipate penetrating components of the material to be shredded from the bearings.
  • Flail and bearing body can be formed both symmetrical and asymmetrical. Unsymmetrical means in this case that they are formed differently wide in the direction of the bearing bore or the bearing body.
  • a cutting body with a beater known which also has a bearing bore penetrated bearing body, in which connects via a connecting portion a beater head.
  • the bearing body is arranged laterally transversely to the bearing axis of the bearing bore.
  • the bore openings in this case have side surfaces.
  • at least one of the side surfaces is segmented segment-shaped at the holes in order to improve the reliability.
  • the object of the invention is, starting from the prior art as described above, to provide a flail which is easier to replace.
  • the object of the invention is achieved by a flail for a crushing device with a rotor on or on which the flail is fastened, consisting of a frusto-conical lower body for connecting the flail to the rotor and at least one cutting body, which is characterized in that Cutting body with the lower body releasably / firmly connected.
  • a development of the invention proposes that the cutting body is designed as a cutting plate or cutting tooth.
  • the plate-shaped or tooth-shaped design of the cutting body is preferred since it can be produced relatively easily in terms of manufacturing technology.
  • the replacement is also easily possible because the cutting body can be attached to corresponding contact surfaces, for example, so that a displacement of the cutting body from a predetermined position is then no longer possible.
  • a preferred embodiment of the invention proposes that two inserts, in particular spaced from each other, are arranged on the flail.
  • the inserts are provided on the lower body. hen, such that the inserts can be removed from the lower body, if necessary because of their condition.
  • the lower body of the flail can then remain on the rotor or on the shaft and need not be changed.
  • crushing tasks for other materials can be realized, eg easily chop long-fiber or softer woods. With the flails of the prior art, there were regularly problems with such crushing tasks.
  • the cutting plates are fastened to the lower body with at least one fastening means.
  • the fastener may be a normal bolt, which is secured with appropriate securing means such as cotter pins or spring washers, so that the screw does not dissolve during use.
  • appropriate securing means such as cotter pins or spring washers
  • the solution according to the invention also includes fastening means such as bolts, wedges, split pins or the like. A protection of the screw can be easily produced by the arrangement of mudguards or discs.
  • the lower body has an eccentric formed extension, which serves to fasten the inserts.
  • This eccentrically shaped extension may for example have a bore through which the one or more fastening means can be performed.
  • the lower body also has a contact surface on or on which the cutting plate (s) can be arranged, in particular, in a form-fitting manner.
  • This may be an annular surface integrally formed on the lower body, which corresponds to the width or plate thickness of the cutting plate and which corresponds to the rounding of the contact surface. has pointing form, so that a form-fitting arrangeability is given. Due to the simultaneous fixing with a fastener, thereby a non-slippable or slip-resistant connection is specified, which, however, in case of service in any case is solvable.
  • the cutting plate on at least one counter surface, which has a corresponding to the contact surface on the lower body shape, such that the cutting plate with this counter surface on the contact surface can be placed.
  • the fixation then takes place via a fastening means on the eccentric-shaped part of the lower body, namely the extension.
  • the extension which extends on the lower body, and which serves in particular the attachment of the cutting plates, is chosen in strength so that the extension serves as a spacer for the cutting plates. Accordingly, an insert is disposed on the left side in the cutting direction and another insert on the right side in the cutting direction. The gap between these two cutting plates is limited by the strength of the extension.
  • the embodiment with two inserts is therefore preferred because it can be achieved more favorable crushing results.
  • the wear on such a configuration is not greater than in conventional mallets. Rather, it has surprisingly been found that such training leads to longer service life in the crushing. With service life is the durability of the inserts to understand.
  • the cutting plates are formed according to a development of the invention such that at least one cutting element is provided on this cutting plate.
  • the cutting element is of course on the cutting direction facing side of the insert.
  • At least one of the cutting elements seen in the cutting direction is wedge-shaped or cylindrical is.
  • the shape of the wedge or the pyramid can be varied according to the crushing tasks to be performed.
  • guide surfaces are further provided which taper in the cutting direction of the cutting plate, such that a guide of the material to be crushed takes place.
  • the guide surfaces may be formed as abrasions and in particular be provided on both sides of the cutting direction facing side, such that a wedge is formed.
  • a through hole is provided, which serves for the attachment of the Schlegels on or on the rotor.
  • the shaft itself may be the rotor. But it is also possible to provide a plurality of such waves on a rotor, so that several such flails or more successive waves in the direction of rotation with flails can be arranged on the circumference of the rotor.
  • a sleeve can be arranged, which serves as a clamping sleeve for fixing the Schlegels on or on the rotor.
  • This clamping sleeve serves in particular to avoid slippage on the shaft.
  • tongue and groove connections are provided here, which also prevent slippage of the flag on the rotor or on the shaft.
  • the invention also relates to a comminuting device with at least one flail, according to one of the previously described variants of the flail according to the invention.
  • the invention will be described below with reference to a single embodiment.
  • Fig. 1 is a perspective view of a

  • FIG. 1 shows a three-dimensional representation of a beater 1 according to the invention.
  • the flail 1 according to the invention consists of the lower body 2, in which the through hole 6 is located.
  • the through hole 6 serves for the flail to be slid onto a shaft (not shown) or onto a rotor. Laterally several flail 1 are then usually arranged side by side and bolted at the end, so that a large number of flails next to each other on a shaft or on a rotor can be arranged.
  • the flail according to the invention can also be used in comminution devices which have a plurality of shafts on a rotor, on or on which a plurality of flails can then be fastened again.

  • a clamping sleeve 7 is shown in the embodiment, which serves for the secure fastening of the bracket 1 on the rotor, not shown, or the shaft, not shown.
  • an eccentric-shaped extension 22 is provided on the lower body 2.
  • This eccentric extension 22 is used to attach the cutting plates 3 and 4, of which a cutting plate 3 seen right in the cutting direction A and an insert 4 left seen in the cutting direction A on the lower body 2 are arranged.
  • the cutting plates 3 and 4 are fastened by a screw 5 to the lower body or to the eccentric-shaped extension 22 of the lower body 2.
  • a contact surface 21 is provided on both sides of the lower body 2.
  • This contact surface 21 can be obtained for example by twisting. It is of course also possible to obtain the entire lower body 2 including the extension 22 as a punching or forging body.
