Definitions

  • the invention relates to a garden shredder with a knife housing arranged on a frame supporting the drive motor and a feed hopper and surrounding a lower ejector chamber, in which there is a knife carrier disk to be driven around a substantially vertical axis, which has essentially radial passage slots and, above it, planer knife-like Arranged flat knives is provided and furthermore, an abutment insert is provided in the knife housing, which has a flat and substantially radially extending lower shear, which cooperates with the cutting edges of the flat knives.
  • the chopping material in particular branch or knot-shaped garden waste, can be fed in unsorted via the feed hopper, since it is sorted by the knife mechanism and in its interaction with the counter-cutting edges on the abutment insert, so to speak, that the larger or stronger knot material from the Flat knives pressed radially outwards and planed in Disc shape is shredded or machined, while the thinner branch and twig material is pressed inwards by the surrounding flat knives in cooperation with the abutment insert to the pre-shredding knives, where it is shredded or shredded more quickly.
  • the flat knives arranged on the knife carrier disc extend with straight cutting edges over the entire length of the lower shear bar interacting with them.
  • the invention is therefore based on the object of improving and perfecting a garden shredder of the type in question in such a way that even stronger branch material can be shredded comparatively quietly and extensively with it without any additional construction and motor effort, so that the garden waste that has been shredded with it, if necessary, can also be shredded can be composted even better than before.
  • this object is essentially achieved according to the invention in that the knife edges consist of short knife-cutting sections which extend over a less than half the partial length range of the lower shearbar interacting with them, and at least some of these knife-cutting sections being offset radially are arranged to each other.
  • the knife edges consist of short knife-cutting sections which extend over a less than half the partial length range of the lower shearbar interacting with them, and at least some of these knife-cutting sections being offset radially are arranged to each other.
  • the flat knives are each provided with a plurality of knife cutting sections located next to one another, but offset in terms of height, which preferably form a continuous, corrugated or angled cutting edge.
  • Flat knives designed in this way thus cut respectively narrow and differently thick or thin chip strips from the respective lower end of the branch material which are then subdivided even more finely as they pass through the passage slots and the ejection area located below the knife carrier disc, so that the chopper as a whole passes through Garden waste leaves it in a comparatively finely divided form and can therefore also be composted particularly well.
  • the desired chip thickness of the comminution material can also be influenced by the fact that the knife carrier disc in its sections adjacent to the passage slots and opposite the flat knives provided with staggered knife cutting sections with the chip thickness of the shredding material additionally determining, higher lying embossing areas.
  • the garden shredder shown only in detail in FIGS. 1 and 2 is provided with a knife housing 1, which is arranged on a frame 4 carrying the drive motor 2 together with the gear 3, which also partially surrounds the ejector chamber 5.
  • the knife housing 1 there is the knife carrier disk 7 to be driven in rotation by the motor 2 via the gear 3 and the shaft 6.
  • radially extending through slots 8 and flat knives 10 arranged behind in the circumferential direction 9 is provided.
  • the pre-comminution knives 11 in the form of two upright and upwardly inwardly curved knife bars 11 ', 11'', which are provided with correspondingly obliquely running cutting edges 11''' in the circumferential direction.
  • an abutment insert 13 with its two-sided fastening feet 13 'is exchangeably fastened in corresponding recesses 12 in the frame 4.
  • This abutment insert 13 consists of one-piece, appropriately shaped iron or steel sheet. This divides the area above the revolving knife carrier disk 7 into a feed area 15 to be fed directly via the feed hopper 14 with the garden waste to be chopped and into the ejector area 16 connected to the ejector space 5. As shown in FIGS.
  • the abutment insert 13 has a flat web part 13 '' which runs flush with its fastening feet 13 'and which comes close to the orbit of the flat knives 10, and an oblique surface 13''' which is angled in relation thereto and has a gate-shaped recess 17 in its area surrounding the pre-shredding knives 11, one of which Gate flank 17 'forms an inner counter cutting edge which interacts with the cutting edges 11''' of the pre-shredding knife.
  • the abutment insert 13 has a lower shear bar 18 which runs essentially radially, but runs tangentially to the enveloping circle of the pre-shredding knives 11 in order to interact with the flat knives present on the knife carrier disk 10 to act on the garden waste material to be chopped in the feed space 15, in particular also thicker branch material, with retracting, inwardly directed cutting action.
  • the consisting of thin-walled sheet or plastic feed or hopper 14 has an obliquely upright outer tube 19, which is fixed with it connected foot flange 20 is easily replaceable on the knife housing 1 or frame housing 4.
  • the vertical partition 21 on the outer tube 19 abuts the upper part of the angled abutment insert 13 and thus ensures that the feed funnel 14 is sealed off from the ejector chamber 5.
  • the knife carrier disk 7 is provided according to FIG. 3 with four radial passage slots 8 arranged evenly distributed over its circumference and the flat knives 10 located behind it in the circumferential direction 9, which are fastened interchangeably according to FIG. 4 in pronounced recesses 7 'by means of two fastening screws 22 each.
  • their knife edges 10 'each consist of a plurality of short knife cutting sections 10' ', 10' '', which extend over a partial length range of less than half of the lower counter cutting edge 18 interacting with them and at least some of these knife cutting sections 10 '', 10 '' 'are arranged radially offset from one another. If L is the length of the lower shear bar 18 on the abutment insert 13, then the short knife cutting sections 10 ′′, 10 ′′ ′′, measured in the radial direction, should be less than L / 2 wide.
  • each flat knife 10 is provided with three such knife cutting sections 10 ′′, 10 ′′ ′′ located next to one another, but offset in height with respect to one another, but these knife cutting sections of different heights are each radially offset from one another in the direction of rotation of the knife carrier disk 7.
  • the two flat knives 10a lying opposite one another are each provided with a knife cutting section 10 ′′ ′′ in the middle and the other two flat knives 10b are provided with knife cutting sections 10 ′′ which are raised at their two ends.
  • the knife cutting sections 10 ′′, 10 ′′ ′′ present on each flat knife overall form a continuous cutting edge 10 ′ that runs in a corrugated or cranked manner, as is also shown in particular in FIG. 5.
  • the knife carrier disk 7 is again provided with four flat knives 10a and 10b, which in the same way as the previously described flat knives each have three knife-cutting sections 10 '', 10 '' 'which are offset next to one another are.
  • the knife carrier disc 7 in its areas adjacent to the passage slots 8, on the side opposite each of the flat knives 10, is additionally provided with the chip thickness D, d of the comminution material, and at elevated embossed areas 7 '' .
  • the desired chip thickness can be additionally varied. As shown in FIG.
  • the individual flat knives 30 are each provided with toothed strip-shaped cutting edges, the teeth 30 'of which and the tooth gaps 30''between them form the cutting knife sections lying next to one another and offset in height from one another.
  • the flat knives 30 have a flat S-shaped overall As shown in FIG. 10 in particular, the profile and can also be provided with toothed strip-shaped cutting edges on both sides and can therefore also be used as a reversible knife. It is understood that particularly narrow chip strips of different thickness can be obtained in these cases.
  • FIGS. 11 and 12 Another embodiment is illustrated in FIGS. 11 and 12.
  • the material to be chopped is only cut one after the other in a narrow strip shape, the chip thickness depending on the height of the individual knife cutting sections 40 ′ being different or also constant. In this case as well, as in the cases described above, the drive power and speeds can be kept comparatively low.
