Definitions

  • the tear plate is preferably completely free of passage slots.
  • the tear strips, as well as the cleaning strips running close above the bottom of the shredder housing advantageously consist of toothed strips arranged uniformly distributed over the circumference of the tear plate, which are preferably arranged radially offset from one another in such a way that a full-surface toothing results on the top and bottom sides.
  • toothed strips arranged uniformly distributed over the circumference of the tear plate, which are preferably arranged radially offset from one another in such a way that a full-surface toothing results on the top and bottom sides.
  • the tear strips are arranged so that they run radially at the top so that their inner ends lead in the circumferential direction of the tear plate and enclose an acute angle with the radial through these ends. which, depending on the speed, lies between 30 ° at low, around 1000 rpm and 45 ° at higher, around 3000 rpm speeds of the drawing plate.
  • the drawing plate is arranged so far below the lower end of the feeding funnel that the passage distance for the material to be torn is between the upper edge of the fangs and the lower feeding funnel adjacent housing cover of the ejector space is between 10 and 20 mm, the smaller distance at lower speeds of about 1000 rpm of the drawing plate and the larger distance at higher speeds of up to 3000 rpm and more should be selected.
  • the like can be used for pre-shredding of rotten branches that are present in the compost.
  • stiff parts close above the drawing plate on the latter carrying drive shaft additional flat pre-shredding knives are mounted and above their outer entry point to the ejector space on the shredder housing an abutment interacting with the rotating knife ends.
  • an effective pre-shredding of corresponding compost components can take place without the fine shredding of the compost to be brought about by the drawing plate being impaired thereby.
  • the pre-shredding knives advantageously consist of double knives provided with mutually mirror-inverted cutting edges, which are to be fastened to the drive shaft by means of screw fastening holes located in the center.
  • two such double knives of identical design can be arranged such that they are offset from one another by 90 °.
  • a tear bar 7 with a radially extending tear teeth 7 ′ and a tear plate 9 provided on the underside with an essentially radially extending cleaning bar 8 are mounted on the top side.
  • the tear strips 7 as well as the cleaning strips 8 running close to the bottom 1 'of the shredder housing 1 consist in the present case of four double toothed strips arranged evenly distributed over the circumference of the tear plate and thus spot welded at the points 9'.
  • Their teeth are advantageously arranged so radially offset from one another that there is a full-surface toothing on the top and bottom of the plate.
  • the tear strips 7 are arranged on the tear plate 9 at an incline radially on the upper side in such a way that their inner ends 7 ′′ lead in the circumferential direction 10 of the tear plate 9 and with the radial axes 11 each running through these ends 7 ′′ enclose an acute angle ⁇ .
  • this angle ⁇ should be selected as a function of the speed, specifically between 30 ° at low speeds of the drawing plate 9 of approximately 1000 rpm and 45 ° at higher speeds of approximately 3000 rpm.
  • the tear strips 7 are able to exert an equally good tearing and centrifuging effect on the material to be shredded.
  • the tear plate 9 at a certain speed-dependent distance below the lower end of the feed hopper 6, in such a way that, according to FIG. 1, the passage distance a for the material to be torn between the upper edge 7 ′′ ′′ of the tear teeth 7 ′ and the housing cover 1 ′′ of the ejector chamber 5 which is adjacent to the lower hopper end is between 10 and 20 mm, wherein the smaller distance at low speeds of about 1000 rpm of the drawing plate 9 and the larger distance at higher speeds of up to 3000 rpm and more should be selected.
  • the fastening screws 12 which are to be screwed into corresponding threaded bores of the drive shaft are used to fasten the tear plate 9 on the drive shaft 3. These penetrate the holes 9 'of the tear plate shown in FIG. 5, which are to be inserted in corresponding diagonally opposite holes 9' and also in corresponding holes 13 'in a spacer plate 13 protruding centering bushes 14 and additionally also grip over the U-shaped profiled angle bracket 15 placed in the screw fastening area.
  • the upright legs 15 'of this angle bracket 15 are offset from one another and lie in the circumferential direction of the tear plate 9 in front of the heads 12' of the fastening screws 12. These are effectively protected against abrasion by the material to be crushed.
  • the material to be shredded is additionally accelerated or thrown outwards by the upright legs 15 'of the U-shaped end bracket 15.
  • This screw fastening is preloaded axially by the spring washers 16.
  • the plates 17 shown below in FIG. 5 and in particular also the abutment plate 18 can be screw-fastened by means of the screws 19 in the flat frame recesses 4 ′, 4 ′′ shown in FIG. 2 in order to remove these recesses after the removal of the already described above Filling built-in abutment smooth wall.
  • the abutment plate 18 is preferably used for the second exemplary embodiment described below and shown in FIGS. 3 and 4.
  • the composting worker shown in FIGS. 3 and 4 differs from that shown in FIGS. 1 and 2 essentially only in that, in addition to the abutment 18 already mentioned, it also has 9 shredding knives 20 above the drawing plate, which have the same fastening screws 12 and the bushings 14 as the tear plate 9 are mounted on the drive shaft 3.
  • the spacer shown in Fig. 5 is then omitted for this assembly 13.
  • the pre-comminution knives 20 consist of double knives provided with cutting edges 20 'which are mirror images of one another on both sides. In the illustrated embodiment, two such, identical double knives 20 are arranged so as to be rotated by 90 ° to one another, so that four knife blades arranged uniformly distributed over the circumference are formed in this way.
  • the central design of the double knife 20 is again shown in particular in Figure 5. It can be seen here that in the knives 20, in addition to a centrally located centering hole 21, which serves to simplify assembly, there are two diagonally opposed closed screw fastening holes 22 and two only semicircular hole recesses 23 offset from one another by 90 °. As can be seen in the drawing without further ado, the two identical double knives are rotatably offset by 90 ° in that the sleeves 14 and of course the screws 12 penetrating them alternately each have an all-round closed bore 22 of one and a semicircular bore 23 of the other double knife 22 penetrate.
  • this pre-comminution knife 20 an effective pre-comminution of branch pieces or similar stalky parts present in the compost material can be carried out without the fine division of the compost material being impaired by the tear plate and its fangs underneath.
  • composting plant designed in accordance with the invention can in principle also be used in garden choppers of different design after the removal of their knife works and the abutment interacting therewith.
  • Garden shredders of this type can then either be operated or used as choppers or compost workers after minor modifications.
  • the new composting plant could equally well be permanently installed in an otherwise appropriately designed garden waste comminution device, so that such a device could then only be used as a composting plant without having to make any modifications to it.
