  • the vents 126 are arranged adjacent to and around the transfer system 1 16 such that material being conveyed and flipped by the transfer system 1 16 can be caught and carried by the air stream. All three vents 126 are arranged in an upward direction, with some of the vents126 being arranged substantially vertically upward to urge material being transferred by the transfer system 1 16 upwards towards the separation system 160 and extraction system 140.

  • the separation system 160 spans at least a substantial portion of the inlet 144 of the chute 140 such that the separation system 160 and the extraction system 140 work in tandem to capture and separate material caught in the air stream.
  • the separation system 160 has two mesh rollers 162 which form a 'rolling grating' over the inlet 144 of the extraction system 140.
  • the mesh rollers 162 are hollow and are configured to rotate in the same direction, clockwise with respect to figure 3, such that material captured from the air stream on a lower surface of the mesh rollers 162 by the extraction system 140 is conveyed rearward, towards the conveyor system 180, by the mesh rollers 162.
  • the conveyor system 180 has an elevator portion 182 with a belt conveyor 184 that extends partially underneath the separation system 160.
  • the belt conveyor 184 is substantially aligned with, or parallel to, a longitudinal axis of the vehicle 10, and extends upwardly at an angle that is transverse to both horizontal and vertical axes.
  • the belt conveyor 184 has plurality of catches 186, in the form of ridges on the belt, configured to catch and support material on the belt as that material is elevated upwards by the belt conveyor 184.
  • the conveyor system 180 also has an offloading portion 188 which is arranged transverse, preferably substantially perpendicularly, to the elevator portion 182 (see most clearly in figure 4).
  • the offloading portion 188 is located below and offloading end of the elevator portion 182 such that material offloaded by the elevator portion 182 is received by an endless conveyor 190 of the offloading portion 188.
  • the offloading portion 188 can be manoeuvred along its longitudinal axis to allow positioning of an offloading end of the endless conveyor 190 as desired (e.g., to a preferred unloading side of the harvester 10).
  • the harvester 10 traverses a field and harvests a crop, such as sugar cane.
  • Harvested crop material is conveyed to the cutting system 1 10 where cutting drums 1 12 cut the harvested crop material into small pieces, such as sugar cane billets.
  • the cut harvested material is then received by the transfer system 1 16 where it is transferred and flipped by the transfer rollers 1 18 over the blower system 120 vents 126.
  • the air stream from the blower system 120 passes through the material and removes at least some extraneous material from the cane billets.
  • the lighter extraneous matter such as thrash, is pushed by the air stream from the vents 126 towards the separation system 160.
  • the extraction system 140 captures the airborne material and draws it towards the mesh rollers 162 of the separation system 160.
  • the negative pressure created by the extraction system 140 vacuums the extraneous matter onto the mesh rollers 162 which rotate that matter towards the conveyor system 180.
  • the conveyor 180 conveys the desirable crop portion of the harvested material that makes it past the separation system 160 and extraction system 140 to be offloaded to infielder vehicles, of the like, running adjacent to the harvester 10.
  • the harvester 10 is particularly well suited to harvesting a single row of stick-type sugar cane, where the cane stalks are harvested whole, or substantially whole, and where any leaf or other waste material is stripped from the stalks.
  • the compact nature of the harvester 10 allows easy transportation (e.g. on a trailer) and results in a low-pressure footprint to ensure minimal damage to the field being harvested.
  • the invention primarily relates to a cleaning system 100, and while a harvester 10 as illustrated in figures 1 to 3 is a preferred application for the cleaning system 100, it should be appreciated that the cleaning system 100 could be applied to other harvester types and, indeed, other vehicle types.
  • the cleaning system 100 is considered to be particularly well suited to a sugar cane harvester 10 as illustrated but, where the context permits, no limitation is meant thereby.
  • the cleaning system provides an efficient system that effectively separates desirable and undesirable portions of a harvested crop.
  • the desirable portion of the crop is conveyed and offloaded from the harvester and the undesirable portion of the crop is extracted and deposited back onto the ground next to the harvester.
  • the separation system ensures that larger desirable portions of the crop are not inadvertently extracted while simultaneously allowing lighter and smaller extraneous material to be either drawn through the separation system or conveyed by the separation system to the extraction system. This results in a higher proportion of extraneous material being removed from the crop as well as in less extraneous material being conveyed with the desirable portion of the crop. Furthermore, as most of the separation happens in an air stream, there is significantly less damage to the crop itself.
  • the terms 'comprises', 'comprising', 'includes', 'including', or similar terms are intended to mean a non-exclusive inclusion, such that a method, system or apparatus that comprises a list of elements does not include those elements solely, but may well include other elements not listed.
