Definitions

  • the present invention pertains to an agricultural harvester, and, more specifically, to a combine header reel.
  • An agricultural harvester known as a “combine” is historically termed such because it combines multiple harvesting functions with a single harvesting unit, such as picking, threshing, separating, and cleaning.
  • a combine includes a header which removes the crop from a field, and a feeder housing which transports the crop matter into a threshing rotor.
  • the threshing rotor rotates within a perforated housing, which may be in the form of adjustable concaves, and performs a threshing operation on the crop to remove the grain.
  • a perforated housing which may be in the form of adjustable concaves, and performs a threshing operation on the crop to remove the grain.
  • a cleaning fan blows air through the sieves to discharge chaff and other debris toward the rear of the combine.
  • Non-grain crop material such as straw from the threshing section proceeds through a residue handling system, which may utilize a straw chopper to process the non-grain material and direct it out the rear of the combine.
  • a residue handling system which may utilize a straw chopper to process the non-grain material and direct it out the rear of the combine.
  • the combine When the grain tank becomes full, the combine is positioned adjacent a vehicle into which the grain is to be unloaded, such as a semi-trailer, gravity box, straight truck, or the like, and an unloading system on the combine is actuated to transfer the grain into the vehicle.
  • a rotary threshing or separating system includes one or more rotors that can extend axially (front to rear) or transversely (side to side) within the body of the combine, and which are partially or fully surrounded by perforated concaves.
  • the crop material is threshed and separated by the rotation of the rotor within the concaves.
  • Coarser non-grain crop material such as stalks and leaves pass through a straw beater to remove any remaining grains, and then are transported to the rear of the combine and discharged back to the field.
  • the separated grain, together with some finer non-grain crop material such as chaff, dust, straw, and other crop residue are discharged through the concaves and fall onto a grain pan where they are transported to a cleaning system.
  • the grain and finer non-grain crop material may also fall directly onto the cleaning system itself.
  • a cleaning system further separates the grain from non-grain crop material, and typically includes a fan directing an airflow stream upwardly and rearwardly through vertically arranged sieves which oscillate in a fore and aft manner.
  • the airflow stream lifts and carries the lighter non-grain crop material towards the rear end of the combine for discharge to the field.
  • Grain and non-grain crop material remaining on the upper and lower sieves are physically separated by the reciprocating action of the sieves as the material moves rearwardly. Any grain and/or non-grain crop material which passes through the upper sieve, but does not pass through the lower sieve, is directed to a tailings pan. Grain falling through the lower sieve lands on a bottom pan of the cleaning system, where it is conveyed forwardly toward a clean grain auger.
  • the clean grain auger conveys the grain to a grain elevator, which transports the grain upwards to a grain tank for temporary storage.
  • the grain accumulates to the point where the grain tank is full and is discharged to an adjacent vehicle such as a semi trailer, gravity box, straight truck or the like by an unloading system on the combine that is actuated to transfer grain into the vehicle.
  • some headers include a rotatable reel to gently guide the crop material to a cutterbar and onward to an auger or a draper.
  • the reel includes axial ends which are susceptible to being wrapped therearound by the crop material, which can negatively affect the operation of the reel if not removed.
  • Known anti-wrap discs serve to prevent crop material from wrapping around on the reel. While these anti-wrap discs serve their purpose well, they require disassembly of the reel to install or are cumbersome to install.
  • the present invention provides an anti-wrap shield mechanism that is easy to install on a reel, using a twist locking geometry.
  • the invention in one form is directed to an anti-wrap shield mechanism of a reel assembly of a header assembly for an agricultural harvester, the anti-wrap shield mechanism including a body configured for being coupled with an end section of the reel assembly, for preventing a crop material from wrapping around at least a portion of the end section during an operation of the reel assembly, and for pivoting to a locked position during an installation of the anti-wrap shield mechanism.
  • the invention in another form is directed to a header assembly for an agricultural harvester, including: a frame; and a reel assembly coupled with the frame, the reel assembly including: an end section; and at least one anti-wrap shield mechanism including a body coupled with the end section, the body configured for preventing a crop material from wrapping around at least a portion of the end section during an operation of the reel assembly and for pivoting to a locked position during an installation of the at least one anti-wrap shield mechanism.
  • the invention in yet another form is directed to a method of using an anti-wrap shield mechanism of a reel assembly of a header assembly for an agricultural harvester, the method including the steps of: providing the header assembly including a frame and the reel assembly coupled with the frame, the reel assembly including an end section, a body of at least one anti-wrap shield mechanism of the reel assembly being coupled with the end section, the body configured for preventing a crop material from wrapping around at least a portion of the end section during an operation of the reel assembly; and pivoting the body to a locked position during an installation of the at least one anti-wrap shield mechanism.
  • An advantage of the present invention is that it provides a way to install the antiwrap shield mechanism by a single person, without excessive tools or unnecessary labor.
  • Another advantage is that it allows for installation and removal of individual antiwrap shield mechanisms and provides a simple way to protect the reel from wrapping crop material.

La présente invention concerne un mécanisme de protection anti-enroulement (125) conçu pour être accouplé à une section d'extrémité (219) d'un ensemble bobine (112) d'un ensemble collecteur agricole (110). Le mécanisme de protection anti-enroulement comprend un corps (227) accouplé à la section d'extrémité (219), le corps étant conçu pour empêcher un matériau de récolte de s'enrouler autour d'au moins une portion de la section d'extrémité durant un fonctionnement de l'ensemble bobine. Le corps est conçu pour pivoter autour d'une alvéole centrale (232) pour le pivotement jusqu'à une position verrouillée lors d'une installation dudit mécanisme de protection anti-enroulement. Le mécanisme anti-enroulement est fixé à l'aide d'une pluralité d'éléments de fixation (235, 244). Ainsi, le mécanisme anti-enroulement peut être installé par une seule personne sans outils excessifs ni travail inutile.
