US 3,967,439 A · Crop divider for a harvester

Abstract

A self-propelled combine has a forward transversely elongated platform with opposite side walls and a transverse harvesting reel extending between the side walls above the cutter bar along the leading edge of the platform. The reel is mounted on a pair of vertically adjustable arms, and a pair of crop dividers are respectively mounted on and extend forwardly of the opposite side walls on transverse pivots that permit vertical floating movement of the crop dividers. The crop dividers have a forwardly converging sheet metal exterior that tapers to a forward shoe that normally rides along the ground, and the inside wall of the sheet metal exterior is disposed inwardly and forwardly of the opposite ends of the reel to deflect crop material away from the opposite ends of the reel and prevent wrapping thereon. The dividers are connected to the reel lift arms by a lost motion mechanism that permits the lifting of the dividers to a transport position after the reel is raised a predetermined amount, and the connection also includes an outrigger that permits the vertical floating movement of the divider while providing lateral stability therefor.

Dependent claims

In a harvesting machine having a forwardly disposed transversely elongated platform including a frame with opposite upright side walls and a crop handling means mounted on the frame and including a harvester reel mounted on and extending between a pair of generally fore and aft arms mounted on the frame for vertical adjustment and including control means for controlling the position of the arms, and transverse crop engaging members having opposite ends inwardly of and adjacent to the side walls, the combination therewith of at least one crop divider mounted on and extending forwardly from a side wall and comprising:

a generally fore and aft divider frame;
a first transverse pivot means adjacent the rearward end of the divider frame swingably mounting the divider frame on the side wall for vertical adjustment relative thereto between a lower operating position and a raised transport position;
a divider skin mounted on the divider frame and including a forwardly converging forward portion tapering to a divider point located adjacent the ground when the frame is in its operating position;
lock means selectively operative between the divider frame and the platform side wall for selectively locking the divider frame to the side wall in a selected position about said first pivot means;
and connecting means operatively connecting the divider frame to the adjacent reel arm for vertical adjustment of the divider when the divider frame is not locked to the side wall in response to a predetermined amount of vertical adjustment of the reel arm.

a generally fore and aft divider frame;
a first transverse pivot means adjacent the rearward end of the divider frame swingably mounting the divider frame on the side wall for vertical adjustment relative thereto between a lower operating position and a raised transport position, a divider skin mounted on the divider frame and including a forwardly converging forward portion tapering to a divider point located adjacent the ground when the frame is in its operating position;
a generally fore and aft outrigger member;
means connecting the rearward end of the outrigger member to the platform frame and including a second transverse pivot means permitting vertical swinging of the outrigger member;
and slide means connected to the divider frame and slidably engaging the opposite sides of the outrigger member to prevent lateral movement of the divider frame relative to the outrigger member, the slide means sliding along the outrigger member to permit vertical swinging of the divider frame.

In a harvesting machine having a forwardly disposed transversely elongated platform including a frame with opposite upright side walls and a crop handling means mounted on the frame and including a harvester reel mounted on the platform and having a plurality of transverse crop engaging members having opposite ends inwardly and adjacent to the opposite side walls, the combination therewith of at least one crop divider mounted on and extending forwardly from a side wall and comprising:

a generally fore and aft divider frame;
means mounting the divider frame on a platform side wall;
a divider skin mounted on the divider frame and including a forwardly converging forward portion tapering to a divider point located adjacent the ground when the divider is in a normal operating position, said forward portion including a generally fore and aft inner wall having a rearward end adjacent to and forwardly of the reel inwardly of the end of the crop engaging members on the reel and a generally fore and aft outer wall disposed outwardly of the ends of the crop engaging members.
