Definitions

  • the invention relates to a support cross for a meat grinder.
  • a multi-part cutting set which comminutes the material to be comminuted, fed via a working auger, to the desired size in several comminution steps, for example by means of a pre-cutter, one or more knives and cutting discs.
  • the last element of such a cutting set is usually a support cross.
  • the knives are mounted on a drivable, rotatable knife pin, so that they rotate together with the knife pin.
  • they have a central shaped recess that is adapted to the cross section of the knife pin.
  • the pre-cutter, the cutting discs and the support cross are non-rotatably arranged in the housing of the meat grinder and have a central bore for the knife pin.
  • the knife pin is connected to the screw conveyor at one end in a rotationally fixed manner and, starting from the connection point with the screw conveyor, has an axially running support section on which the knives rest.
  • one end of the knife pin, the insertion end is inserted into the bearing bore of the screw conveyor.
  • the fastening ring which is pushed onto the blade pin and rests against the stop surface of the blade pin, is then connected to the conveyor screw.
  • This connection is a detachable connection.
  • a new support cross is proposed for a meat grinder, which in a known manner comprises a hub with a central bore, an outer ring and a plurality of webs which extend between the hub and the outer ring. There is a groove on the outside of the outer ring for non-rotatable mounting of the support cross in the meat grinder.
  • this support cross has a tool function.
  • such elements are present on a face of the hub. These elements can serve as engagement elements, for example when dismantling the knife pin.
  • the lugs protrude from the end face of the hub, ie from the front or rear of the supporting cross.
  • the arrangement of the lugs is important.
  • the fastening ring must be loosened in order to dismantle the knife pin described above.
  • This mounting ring holds the knife pin in the auger.
  • the support cross is pushed onto the knife pin and rotated in such a way that the lugs on the support cross are aligned with corresponding recesses or notches in the fastening ring.
  • the support cross is pressed against the fastening ring, the lugs engaging in the recesses or notches of the fastening ring. Now the fastening ring can be loosened by turning the support cross.
  • the new cross brace clamps the elements of the cutting set in the housing of the meat grinder in a known manner together with a locking nut.
  • the new support cross has an additional function, namely a tool function. In one embodiment of the invention, it can serve as an assembly or disassembly tool for the knife pin. Advantageously, no additional tool is required for the assembly and disassembly of the knife pin. In other implementations, a spider has other tool functions.
  • FIG. 1 shows a perspective view of a support cross according to the invention
  • FIG. 5 shows a front side of another support cross according to the invention
  • FIG. 6 shows a sectional view of the support cross according to FIG. 5,
  • the support cross 10 shown in the figures is the last element of a cutting set in the meat grinder.
  • this support cross 10 has three webs 12 which connect an outer ring 13 and a central hub 11 .
  • a central bore 15 is provided in the hub 11 .
  • the hub 11 has two lugs 16, 16' on its end face.
  • there is a groove 14 on the outer ring 13 which interacts with a corresponding feather key on the housing wall of the meat grinder and thus prevents the support cross 10 from rotating during the comminution process.
  • the feather key is removed and the support cross can be rotated.
  • FIG. 2 shows the screw conveyor 40, the knife pin 30 and the fastening ring 20 used to connect the knife pin 30 to the screw conveyor 40.
  • Two sealing rings 50, 51 are additionally provided in this exemplary embodiment.
  • One end of the knife pin 30 is inserted into the screw conveyor 40 .
  • Fastening ring 20 which has a suitable thread for a screw connection to conveyor screw 40 , is pushed over knife pin 30 .
  • the support cross 10 is then also pushed over the narrower part of the knife pin 30 and the support cross 10 is aligned in such a way that the two lugs 16, 16' can engage in the two recesses 21. If the support cross 10 is pressed tightly against the fastening ring 20, the support cross 10 can be rotated.
  • the webs 12 of the support cross provide a handle for this.
  • the rotational movement of the support cross 10 is transmitted to the fastening ring 20 by the engagement of the lugs 16, 16' in the recesses 21 and the screw connection to the screw conveyor 40 is thus tightened.
  • the knife pin 30 is also dismantled with the aid of the support cross 10. An additional tool therefore does not have to be available.
  • the lugs 16, 16' are on the outer edge of the hub 11. This arrangement has been chosen so that the lugs 16, 16' fit into the peripheral notches 22 of the mounting ring 20', shown in Figure 4. can intervene.
  • the assembly and disassembly process of the knife pin 30 with the aid of the support cross 10 from FIG. 3 takes place as described in the previous example.
  • the support cross 10 has a bearing bush 17 received in the central bore 15.
  • Such bearing bushes 17 are used in support crosses and cutting elements of the meat grinder in order to, after a certain period of operation, only having to replace the bearing bush and not the spider or blade set element.
  • the two lugs 16, 16' are located diametrically opposite one another on the front side of the bearing bush 17.
  • the lugs 16, 16' protrude from the front side .
  • the lugs 16, 16' are provided on the outer edge of the bearing bush 17, see FIG. 8.
  • the bearing bush 17 has an inner bore in which the knife pin 30, shown in FIG. 2, can be received in a rotatable manner.
  • the bearing bush 17 has a front area with a larger outer diameter - left side in Fig. 7 and a rear area with a smaller outer diameter - right side in Fig have a different inner diameter, so that a step is formed.
  • the assembly and disassembly process of the knife pin 30 with the aid of this support cross 10 from FIG. 5 takes place as already described.
  • the step inside the hub 11 prevents the bearing bushing 17 from being pressed backwards through the central bore 15 during the assembly or disassembly process. It forms a stop area for the front area of the bearing bush 17.
  • the front area with the larger outside diameter is also designed as a ring, but the rear area Area has a different shape from the round ring, for example, has an oval cross-section perimeter.
  • elements with a tool function are not provided in the area of the hub 11 but also on the webs 12 or the outer ring 13 .

Abstract

L'invention concerne un support en forme de croix (10) pour un hachoir à viande. Le support en forme de croix (10) présente un moyeu (11) avec un alésage central (15), une bague externe (13) et de multiples éléments de liaison (12) qui s'étendent entre le moyeu (11) et la bague externe (13). Une rainure (14) est disposée sur l'extérieur de la bague externe (13) pour supporter de manière solidaire en rotation le support en forme de croix (10) dans le hachoir à viande. Le support en forme de croix (10) fonctionne en outre en tant qu'outil, par exemple le support en forme de croix a des saillies (16) qui permettent une simplification de l'assemblage ou du démontage de la broche de couteau du hachoir à viande (Fig. 1).
