Definitions

  • the invention relates to a chopper for shredding rotten material, in particular woody garden waste such as branch material, with a drivable cutting roller arranged in the region of the lower end of a loading chute, which is arranged with an axis running transversely to the axis of the charging chute and has circumferential cutting teeth, between which tooth gaps are provided.
  • a chopper of this type is known from DE 30 36 235 A1.
  • This known arrangement has no device for pressing and squeezing the material to be chopped. The consequence of this is poor mechanical disintegration of the chopped material, which makes subsequent attack by rotting organisms more difficult. A very slow rotting process can therefore be expected.
  • US-A 4 351 488 shows a device for shredding plastic waste, which also has a cutting roller arranged at the lower end of a loading chute, which is equipped with knife bars projecting over the roller circumference and arranged in respectively assigned grooves which interrupt the roller circumference.
  • the knife bars of the cutting roller work with a stationary one Counter knife together, which is received on a rail flanking the cutting roller, which is arranged non-adjustable.
  • the material entering the feed region of the cutting roller is machined with a chip thickness corresponding to the protrusion of the knife bars over the circumference of the roller. There is no pressing and squeezing of the machined material beyond the force applied during this machining process. If such an arrangement were used for the shredding of decomposable material, there would therefore be no significant crushing and splitting of the shredding material.
  • the cutting roller is flanked by a descending narrowing gusset with its descending circumferential half, which is adjustable with respect to the cutting roller and which presses the material caught by the cutting teeth of the cutting roller into the tooth gaps provided between the cutting teeth.
  • the measures according to the invention ensure that the material drawn in by the cutting teeth along the press plate is reliably pressed and squeezed and splintered in the process. Since the material pressed into the tooth gaps tries to evade laterally within the tooth gaps, one results particularly good fragmentation.
  • the measures according to the invention also prevent impact noise. The fact that the material drawn in by the cutting teeth along the press plate, which acts practically as a feed table, is applied to and pressed against the latter, ensures a reliable hold-down effect and thus the elimination of impact noise and a reliable drawing in and separating cut.
  • the tooth gaps can expediently have a cross section which is approximately half the area of one through the Head circle of the cutting roller, which corresponds to this pressing plate and a tangent to the pressing plate perpendicular to the tip circle of the cutting roller delimited squeeze triangle.
  • a further, particularly preferred measure may consist in the cutting teeth being designed without rake angles. Because no rake angle is provided, comparatively large healing and clearance angles can be provided. This results in a particularly large head thickness and thus a particularly high stability of the cutting teeth.
  • the main advantage of this measure can be seen in the fact that the cutting teeth without rake cut slowly into the material to be chopped and, accordingly, reliably pull it in without cutting it prematurely. The advantageous pressing and squeezing effects of the press plate can therefore be particularly effective here.
  • the garden shredder shown in the drawing consists of a cutting and crushing mechanism 2 standing upright on legs 1 with a cutting roller 3 which is arranged with a horizontal axis and can be driven slowly, here with 50 revolutions / min 10 is provided. Above the cutting roller 3 there is a feed shaft 4 arranged with a vertical axis and below it a discharge shaft 5 arranged with a vertical axis. An insertion funnel can be provided at the upper end of the feed chute.
  • the cutting and squeezing mechanism 2 has two lateral, parallel bearing plates 7, on which the cutting roller 3 is mounted and on which the feed chute 4 and ejection chute 5 rest and are fastened with side walls parallel to the shield.
  • the continuous cutting roller 3 over the entire clear distance between the end plates 7 interacts in the region of its downwardly moving peripheral half with a press plate 17, which is followed by a separate counter knife arrangement.
  • the pressure plate 17 is accommodated on a crossbar 18 bridging the two end shields 7, as indicated by adjusting screws 19.
  • the pressure plate 17 is set so that it touches the tip circle K of the cutting roller 3 without collisions, as indicated at 24.
  • the press plate 17 is inclined away from the circumference of the cutting roller to form a funnel effect, so that the tip circle K is affected below the height of the axis of the cutting roller 3.
  • the material to be chopped which is indicated here in the form of a branch 21, is pressed in, and this material is pressed and squeezed.
  • the material feed is effected by the cutting teeth 10 of the cutting roller 3, which move downwards on the feed side and cut into the material to be drawn in.
  • the cutting teeth 10 of the cutting roller 3 have a comparatively large wedge angle of 60 ° and a clearance angle of 30 °. A rake angle is not provided. In this way, on the one hand, a comparatively large head thickness of the cutting teeth 10 of here 5 mm and thus a high tooth stability can be achieved and, on the other hand, a premature cut can also be avoided. This is because the cutting teeth 10 without rake cut comparatively slowly into the material to be drawn in. This is reliably drawn in, but not cut off prematurely.
  • the material drawn in by the teeth 10 running along the roll length along the press plate 17 acting as the feed table is pressed onto the press plate 17 during the pulling-in and thereby pressed into the tooth gaps 22 between the cutting teeth 10, with tooth gaps 22 also passing through the roll length of course there is a lateral evasion of the material. Due to this squeezing and pressing process, the one to be processed The material has already undergone good mechanical digestion, which facilitates subsequent attack by rotting organisms.
  • the cross-section of the tooth gaps 22 is 50% of the cross-section of the gusset 20 acting as a squeezing triangle between the tip circle K, the pressing plate 17 tangent to it and one, as is shown by different hatching perpendicular to this tangent to the tip circle K.
  • the length of the upper delimitation 23 of the squeeze triangle formed by the aforementioned tangent corresponds to half the tip circle diameter D of the cutting roller 3.
  • the optimum size for the maximum processable branch thickness is somewhat smaller. This is 3/10 to 4/10 of the diameter D of the tip circle K of the cutting roller 3.
  • the material to be processed is split up and thus mechanically disrupted, which facilitates the later attack by rotting organisms.
