Definitions

  • the invention relates to a device for grinding grain, in particular maize, with a housing in which a ring sieve for the passage of ground material is supported in a stationary manner, and with a number of grinding tools which can be driven circumferentially within the ring sieve and are arranged at an angular distance from one another, while being left an annular gap along the inner peripheral surface of the ring sieve can be guided.
  • the invention has for its object to provide a device for grinding cereals, in particular corn, in which malfunctions caused by light regrind suspended in the interior of the device housing are largely avoided and which can be operated at high operating speeds.
  • the grinding tools are provided on their side facing away from the ring sieve with a row of recesses running in the longitudinal direction of the tool, through which the free ends of a set each of them in turn within the ring sieve for circulation against the direction of rotation of the grinding tools impact tools rotatably supported in the device housing.
  • the ring sieve is largely relieved of its function as a counter-tool for the rotating grinding tools for comminuting the material to be ground, since the essential comminution work is carried out by the opposing rotating and interacting grinding and beating tools for comminuting the material to be ground.
  • the comminuted ground material driven by centrifugal force to the ring sieve, is only passed through the sieve meshes in an accelerated manner, without any significant comminution work being necessary, which would result in blockages of the sieve meshes in some areas.
  • even light-weight regrind components such as, in particular, corn spindle components, can be conveyed through the meshes of the ring sieve and out of the device housing at the speed required for high-performance operation of the device.
  • the counter-rotating movements of the grinding tools, in particular knives, on the one hand and the striking tools, in particular Schlegel, on the other hand, can be easily achieved by maintaining the tools in the manner of a planetary gear while maintaining a compact design of the device introduce.
  • the device shown in the drawing is used to grind cereals, in particular maize, harvested maize cobs as a whole, ie the maize spindle and the maize kernels, being crushed.
  • the device comprises a housing 1 with an end wall 2, a peripheral wall 3 and an end ring 4.
  • an annular sieve 6 is fastened for the passage of ground material by means of an annular flange 5.
  • the end ring 4 or the ring sieve 6 delimits an open end side 7 opposite the end wall 2 . of the housing 1, which is connected to a feed device (not shown) for the regrind.
  • a bearing block 9 is fastened to the housing 1, the bearings 10 and 11 of which rotatably support a central shaft 12.
  • the shaft 12 is connected at its end 13 to a suitable drive means, while its other end 14 extends centrally into the housing 1 and is secured in the plane of the housing opening 7 by an end plate 15.
  • a rotor disk 16 is located on the shaft 12 within the housing .1 attached, which rotates with the shaft 12 parallel to the housing wall 2 at a short distance from this.
  • a number of grinding elements 17 in the form of knives in a region within the circumscribed by the annular sieve 6 annular space while leaving a narrow annular gap 18 is secured with a uniform angular distance from one another.
  • the knives 17 are designed in the form of strips and are fastened to the rotor disk 16 with their ends 12a projecting freely, and in their circumferential direction shown in FIG. 2 by an arrow .19 taper to the ring sieve 6 by a bevel.
  • the knives 17 are each provided with a row of recesses 20 which run in the longitudinal direction of the tool and through which the free ends of a set each of them in turn within the ring sieve 6 for circulation against the direction of rotation 19 of the knives 17 are rotatably supported in the device housing 1 striking tools 21.
  • the striking tools 21 are in the form of flails, which are each pivotally supported in sets on bearing bolts 22 on the outer circumference of a cylindrical flail housing 23.
  • the bearing bolts 22 are fastened in the cheeks 24 of a circumferential part 25, which permits a limited pivoting of the flails 21 around the respective bearing bolts 22.
  • the recesses 20 on the back of the knife correspond in their rectangular cross-sectional shape to that of the flail 21 and form with their free end regions cooperating shear gaps 26 for crushing the ground material.
  • the flail housing 23 is provided on its inner circumference in the manner of a planetary gear with an internally toothed large wheel 28, which in the example shown is in mesh with three planet wheels 29 which in turn mesh with a sun gear 30.
  • the planet gears 29 are fixed on bolts 31 which are rotatably supported at the ends by bearings 32 in the two end walls 33 of the flail housing 23.
  • the sun gear 30 is fixedly connected to a hub 34, which in turn is connected in a rotationally fixed manner to the knife drive shaft 12 by means of a wedge connection.
  • the two end walls 33 of the flail housing 23 are rotatably supported on the sun wheel hub 34 via bearings 35.
  • the exemplary embodiment according to FIGS. 3 and 4 shows another drive switch for the rotation of the knives 17 and the flails 21 in opposite directions of rotation.
  • the knife drive shaft is designed as a hollow shaft 36 which is rotatably mounted in the bearing block 9 of the housing 1 via the bearings 10 'and 11'.
  • the hollow shaft 36 carries the rotor disk 16 with the knives 17 according to the exemplary embodiment according to FIGS. 1 and 2, while at its other end it comprises a gear housing 38 enclosing an inner annular space 37.
  • the gear housing 38 is in turn provided on its inner circumference in the manner of a planetary gear with an internally toothed large wheel 39 which, in the example shown, is in mesh with three planet wheels 40.
  • the planet gears 40 are each rotatably supported in the bearings 42 on the end walls 43 of the gear housing 38 by means of their support bolt 41.
  • a sun gear 44 which is connected to a central shaft 45 in a rotationally fixed manner, is in mesh with the planet gears 40.
  • the shaft 45 is secured at the end by end disks 46 and extends with its end region 47 facing away from the sun gear 44 into the middle of the flail housing 23, to which it is connected in a rotationally fixed manner by means of a wedge connection 48.
  • the hollow shaft 36 and the gear housing 38 which form a unit, are rotatably supported on the central shaft 45 via bearings 49, 50 and 51.
  • the flail housing 23 is kept free of gears in this case.
  • the knife drive shaft 12 is, for example, in the embodiment according to FIGS. 1 and 2 driven in a direction of rotation counterclockwise, so that the knives 17, which are fixedly connected to the cutter shaft 12 via the rotor disk 16, in turn rotate counterclockwise according to the directional arrow 19.
  • the sun gear 30 then also rotates counterclockwise in accordance with the direction arrow 52 and, via the intermediate or planet gears 29, mediates a clockwise rotational movement for the internally toothed large wheel 28 of the flail housing 23 for the counterclockwise rotation of the flails 21 in accordance with the direction arrow 27 .
  • the gear housing 38 is driven counterclockwise by the cardan shaft of the motor unit of an agricultural device, so that the knives 17 in turn also rotate counterclockwise.
  • the sun gear 44 or the shaft 45 receives a clockwise rotation, so that the flails 21, as in the case of the first embodiment, perform one of the counter-rotating movements of the knives 17.
  • the regrind comminuted by the interaction of the knives 17 and the flails 21 is pushed through the sieve 6 by centrifugal force, supported by the knives 17, and reaches an outer annular channel 53 of the housing 1 surrounding the outer ring sieve 6, which is separated from the housing walls 2, 3 and 4 is limited on the outside.
  • Ejector blades 54 circulate within the annular space 53 and are fastened to the rotor disk 16, adjacent to its outer peripheral edge. The revolving ejector blades 54 expel the ground material from the ring channel 53, which is connected via a suitable outlet opening to a device which conveys the ground material in a manner not shown in any more detail.
