Definitions

  • the invention relates to a device for comminuting vegetable or other waste subject to decomposition, with at least two screw conveyors rotatably mounted in the end housing walls, with counter-driven or oppositely aligned conveying paths, with longitudinal axes running in superimposed planes and with a comminuting device having rotating comminution tools.
  • the waste material is circulated with the aid of driven vertical conveyors (DE-A 31 04 769).
  • driven vertical conveyors DE-A 31 04 769
  • rotating comminution rollers running transversely to the conveying screws are arranged on the material intake belt and at the outlet opening of a conveying channel bordering the upper conveying screw, into which a vertical conveyor also opens.
  • This training limits the functionality of this known device to smaller, light waste.
  • bulky, hard waste e.g. B. trunks, branches and the like.
  • the vertical conveyor and the upper conveyor channel do not guarantee multiple circulation and multiple shredding, because on the one hand they cannot pick up bulky objects and on the other hand run the risk of clogging very quickly.
  • the transverse comminution rollers require special bearings and drive means, so that the construction and assembly work and ultimately the production costs are considerable.
  • a comminution device is known from DE-A 26 00 454 in which two counter-rotating, intermeshing knife shafts are arranged above a lower worm, which is partially provided with round blanks.
  • the intermeshing arrangement of the knife shafts likewise does not permit multiple circulation or multiple shredding, so that the material to be shredded cannot be transported from lower housing interior areas to conveying elements in order to be passed on to the shredding tools for a renewed shredding process.
  • the invention provides that the rotating grinding tools of the shredding unit are arranged at a distance from the front housing wall on the conveyor screw located in the lower horizontal plane in a longitudinal end region near the end housing wall, the conveyor screw being configured with a conveying disk between the front housing wall and the shredding unit.
  • the shredding device according to the invention can be produced with little construction effort and thus low costs with full functionality for wide areas of application.
  • the comminution device which in the exemplary embodiments shown is designed as a hanger equipped with a drawbar 2, an axle 3 and wheels 4, is generally designated by 1.
  • This trailer is to be attached to an agricultural tractor or other suitable towing vehicle, can be driven to a desired location as required and is particularly suitable for municipalities, agricultural and forestry companies and the like.
  • the shredding wagon 1 is provided with side housing walls 5 and front and rear with vertical housing walls 6.
  • the housing has an essentially funnel-shaped cross-sectional profile and is delimited at the bottom by a housing base 8 and at the top by a housing cover 7.
  • the material to be composted is introduced from above into the comminution wagon and, after comminution and mixing, is discharged from the device via a flap 10 attached to a lifting cylinder 9 and a discharge belt 11.
  • screw conveyors 16, 18, 19 having oppositely oriented conveying passages 14 or conveying discs 15 are arranged in the interior of the housing in two superimposed horizontal planes 12 and 13.
  • parallel screw conveyors 18 and 19 are arranged with longitudinal axes 20 and 21 extending in the upper horizontal plane 13.
  • the lower screw conveyor 16 and the two upper screw conveyors 18 and 19 are rotatably supported in bearings 22 and are driven by means 23 set in motion.
  • the drive means 23 can comprise an independent motor drive unit. In the exemplary embodiment shown, the drive means 23 are to be coupled via a connection 24 to the PTO shaft of an agricultural tractor, not shown.
  • Comminution tools 26 are arranged according to the invention in the longitudinal end region 25 of the lower screw conveyor 16 near the front vertical housing wall 6.
  • This longitudinal end region 25 is designed to be free of circular blanks and is delimited towards the front of the carriage 1 by a partial conveying disc 27, which is oriented in the opposite direction to the main conveying disc 15 of the lower screw conveyor 16, as a storage shield.
  • the parallel screw conveyors 18 and 19 located in the upper horizontal plane 13 are each formed on their longitudinal end regions 28 and 29 near the rear vertical housing wall 6 and are equipped with round bars running perpendicular to the longitudinal axes 21 as vertical conveyor fingers 30.
  • Comminution tools 26 and the vertical conveyor fingers 30 are each offset in the circumferential and longitudinal directions of the screw conveyor 16 and the screw conveyors 18, 19.
  • the longitudinal end regions 28 and 29 of the upper screw conveyors 18 and 19 are also delimited with partial conveyor rounds 31 and 32 as storage shields.
  • the staggered cutting tools 26 are designed as cutting knives and interact with cutting blades 33 supported on the lateral housing walls 5.
  • 5 recesses 34 are provided in the side housing walls, so that the cutting blades 33 are to be introduced into the shredding device 1 from the outside.
  • the cutting blades 33 extend transversely below the lower screw conveyor 16 through the interior of the housing and the recesses 34 to the outer sides of the side Housing walls 5.
  • Fixing flanges 35 and 36 are provided on the side housing walls 5 to support the cutting blades 33.
  • One end of the cutting blade 33 is articulated on the housing flange 35, whereas a tension spring 37, which in turn is held on the housing flange 36, acts on the opposite end region.
  • the recesses 34 each have a width that allows the cutting blades to deflect as soon as an obstacle, for example a stone that is carelessly introduced into the comminution device, gets into the cutting mechanism. Furthermore, this resilient support of the cutting blades 33 protects the cutting mechanism against unnecessary destruction and against jamming of hard materials that are difficult to shred. By inserting the cutting blades 33 from the outside, the cutting blades can be exchanged and replaced easily and quickly. If the cutting unit is jammed, the fault can be remedied from the outside without emptying the device.
  • the cutting blades 33 can also be supported on the housing base 8 and run through recesses provided there.
  • the lower screw conveyor 16 is provided with a conveyor disc 15 which has tooth-like recesses 38 on its outer surface. These recesses 38 mesh with knobs 39 fastened to the housing base 8, which run at a distance from one another below the longitudinal axis 17 of the lower screw conveyor. These knobs act as additional cutting tools. Likewise, the action of the knobs on the conveyed compost material effectively prevents unwanted winding of waste onto the screw conveyor 16. Instead of the knobs, other suitable projections such as cutting strips and the like can also be provided.
  • a section of a lower screw conveyor 16 is illustrated, which on its disk surface with in the Conveying path 14 projecting angle profiles 40 is provided.
  • the angular profiles are formed by sheets welded to the outer edge of the conveyor disk 15, so that the conveyor disk 15 has an angled profile in cross section.
  • the waste After the waste has been disposed of, it reaches the upper screw conveyors 18 and 19 or falls into the funnel-shaped housing bottom space which is controlled by the lower screw conveyor 16.
  • a tricher-shaped housing e.g. use a box-shaped housing, the bottom of which is dominated by two lower conveyor screws designed according to the invention.
  • the two upper screw conveyors 18 and 19 convey the waste to their rear longitudinal end regions 28, from where they are transferred to the lower screw conveyor 16 with the support of the vertical conveyor fingers 30.
  • the rear bearings 22 of the two upper screw conveyors 18 and 19 are effectively protected against the ingress of waste material by the partial conveyor discs 31 and 32.
  • the waste material reaches the cutting tools 26 or the cutting blades 33 and is comminuted.
  • An extremely hard log between the cutting tools 26 and cutting blades 33 which can only be shredded, prevents the pivoting mounting of the cutting blades 33 from jamming the cutting mechanism.
  • the advancing shredded material moves the compost on the front vertical housing wall 6 vertically upwards to the upper screw conveyors 18 and 19, so that renewed circulation can take place, with special e.g. mineral fertilizers are added.
