Abstract

A crop harvesting header includes a cutter bar arranged across a forward edge, a draper or auger transport arrangement for transporting the cut crop, and a reel mounted on reel arms having a plurality of reel bats at spaced positions around the reel axis each reel bat having reel fingers projecting generally radially outwardly from the reel axis. Each bat is mounted for pivotal movement about its bat axis. At both ends of each bat is mounted a crop divider which pivots with the bat and is formed with a plate lying in a radial plane of the bat with angularly spaced fingers around the outer edge. A leading edge of the plate and front finger is convexly curved relative to the concave curve of the front edge of the finger and is angularly advanced relative to the leading edge of the adjacent fingers such that the rotating crop dividers on the reel co-operate with a stationary crop on the header to separate the cut crop from uncut crop passing alongside the end of the header.

Dependent claims

A crop harvesting header comprising:

a header frame structure arranged for movement in a direction of working movement across ground carrying a crop to be harvested;
a cutter bar arranged across a forward edge of the header frame structure for cutting the crop, the cutter bar having ends at respective ends of the header;
a cut crop transport arrangement mounted on the header frame structure for receiving and transporting the cut crop for further processing;
and a reel for controlling movement of the crop in the area over the cutter bar, the reel having ends at respective ends of the header;
the reel being mounted on the header frame structure for movement therewith in the direction of movement and for rotation about a reel axis generally parallel to the cutter bar;
the reel having a plurality of reel bats at spaced positions around the reel axis with each reel bat having a row of axially spaced reel fingers projecting generally outwardly from the reel axis;
each bat being mounted for pivotal movement about a bat axis parallel to the reel axis, the angular position of each of the bats about its axis being controlled by a linkage of the bat which co-operates with a cam of the reel so that, as the reel rotates, the linkage moves the bats to a required angular position in dependence upon the co-operation of the linkage with the cam;
each of at least some of the bats having mounted on at least one end thereof axially spaced from an endmost one of the fingers a crop divider member which crop divider member is axially spaced from the linkage, rotates with the reel around the reel axis for engaging crop at the end of the reel and pivots with the bat about the bat axis;
each divider member being shaped differently from the fingers and shaped for dividing the crop such that a part of the crop inboard of the reel end to be cut by the cutter bar is separated by the divider members from a part of the crop outboard of the reel end which passes outwardly of the respective end of the cutter bar and is not cut.

each of at least some of the bats having mounted on at least one end thereof axially spaced from an endmost one of the fingers a crop divider member which rotates with the reel around the reel axis for engaging crop at the end of the reel;
wherein in respect of each bat having at least one divider member thereon:
each of the fingers of the bat extends angularly from a leading edge to a trailing edge;

the fingers are curved such that the leading edge thereof, when viewed in side elevation, is concave and such that the trailing edge thereof, when viewed in side elevation, is convex;
and the leading edge of each divider member, when viewed in side elevation, is convex.
