Definitions

  • the invention relates to a machine for crushing garden waste such as branches and leaves of shrubs or the like. with a filling opening preferably formed above a housing by a funnel and an outlet opening preferably located on the underside of the housing and a motor-driven cutting device arranged in between.
  • an elliptical swash plate is attached as a cutting tool in the housing between the funnel / on a rotatably mounted drive shaft, on the circumference of which cutting edges are formed which interact in a cutting manner with a cylindrical inner wall of the housing .
  • the cutting edges arranged circumferentially on the swashplate constantly move back and forth on the inner wall of the cylindrical housing and show an excellent cutting performance without causing clogging.
  • the machine shows a smooth run without vibrations.
  • the material to be cut is special peculiar movement of the swashplate the cutting edges fed particularly well.
  • the swash plate is also releasably supported on the drive shaft and can therefore be replaced, the individual parts subject to wear can be easily replaced.
  • a sheet metal strip can extend as an abutment for the cutting edges on both sides of the funnel opening.
  • the cylindrical metal strips run radially on the inner surface of the U-shaped housing and leave the outlet opening free on the underside.
  • the swash plate is further preferred to attach the swash plate to the drive shaft at an acute angle, the imaginary vertical center line of the swash plate being arranged centrally between the two metal strips in such a way that the cutting edges of the swash plate cover the inner side surface of the metal strips.
  • a machine for shredding garden waste consists of a housing 11 held by four supports 10, on the upper side of which a funnel 12 is arranged.
  • the housing 11 is formed by a cylindrical jacket 13, which has the shape of an inverted U in cross section, and two congruent end walls 14, which are welded to the jacket 13.
  • a Outlet opening 15 is open to the outside, while at the top of the casing 13 an opening 16 connects the inner cavity of the housing 11 to the funnel 12 and via its upper fill opening 17 to the outside.
  • a horizontal drive shaft 18 in the longitudinal direction, which is mounted in bearings 19 of the two end walls 14.
  • a stump of the drive shaft 18 running outside the housing 11 is connected to a drive motor.
  • a swash plate 21, 22 serves as the cutting tool of the machine, which is fastened, for example welded, as an elliptical disk within the housing 11 between the funnel 12 and the outlet opening 15 on the drive shaft 18.
  • the plane of the swash plate 21 is at an acute angle to the axis of the drive shaft 18, so that material filled via the funnel 12 is provided with a movement by the swash plate 21 when the drive shaft 18 rotates, which movement is horizontal , Has component running in the direction of the axis of the drive shaft 18.
  • the material is thus conveyed to the outer edges of the elliptical swash plate 21, which are designed as cutting edges 23, where it is cut adjacent to the inner cylindrical surface of the housing 11.
  • the outer edges of the swash plate 22 are not designed as cutting edges, but rather this plate has grooves 24 and 25 on its surfaces and on its circumference, in which exchangeable cutting knives 26 are inserted and fastened with the aid of screws 27.
  • the cutting knives 26 have cutting edges 28 which lie in the region of the outer edges of the swash plate, so that this swash plate 22 also performs its cutting task when the drive shaft 18 rotates.
  • the cutting blades 26 can easily be replaced for grinding.
  • Interchangeable sheet metal strips 29 and 30 are arranged on the inner surface of the casing 13 on both sides of the swash plate 21 and 22, respectively, which surround the cutting edges 23 and 28 of the swash plate 21 and 22, respectively.
  • These metal strips made of hardened steel also act as cutting edges with their edges facing the swash plate, the metal strips 29 according to FIG. 2 of the drawing being provided with special cutting tips 31 here.
  • the metal strips 29 and 30 are fastened to wedges 32 which are fastened, for example welded, to the inner surface of the jacket 13.
  • the sheet strips 29 and have for this purpose 3o B efest Trents- holes 33 which are passed through the screwed-in the wedges 32 screws 34th
  • the area of the elliptical swash plate 21, 22 corresponds to the area of the cylindrical section of a circular cylinder with the radius of the casing 13 along the swash plate plane, so that the outer edges of the swash plate 21, 22 always lie against the inner surface of the cylindrical casing 13 in its curved region and there can perform their cutting movements.
  • the housing 11 forms a semicircle in cross section in the upper region, in which the inlet opening 16 is arranged and the side walls of which run vertically downwards.
  • the sheet metal strips 29, 33 rest, which are cylindrical in shape and open on the underside. This open part is part of the outlet opening 15.
  • the wedges 32 are located to support the sheet metal strips 29, 33.
  • the fixed to the drive shaft 18 at an acute angle swash plate 21 is fixed preferably inclined with respect to the imaginary vertical center line at an angle of almost 0 ° 3.
  • the cutting edges 23 of the elliptical swash plate 21 grip over the edge area of the inner surfaces of both sheet metal strips 29 alternately (above and below) and cut the material in the abutting edge area of the sheet strip edges 3oa and the cutting edges 23 of the swash plate 21 Fibrous or sheet-like material is produced by the swash plate 21, which changes in terms of area, or the edges thereof, in relation to the metal strips 29, 30 arranged laterally thereto, at right angles to the fiber of the material to be cut, which is given a relatively short cut.
  • the circumferential outer surface of the elliptical swash plate 21 is cylindrical in accordance with the inclined position, the outer surface of its smaller diameter being perpendicular to its plane, while the outer surface is adapted to the larger inclined position of the respective inclined position. The lateral surface is thus twisted from the smaller to the larger diameter.
  • the cylindrical inner surface of the housing on both sides of the funnels can also serve as a counter surface for the cutting edges of the swash plate.
