Abstract
A tine connection device for removably connecting a tine to an elongate tine bar in an agricultural harvesting machine wherein the device comprises a mounting base that is contoured to simultaneously engage the tine bar and a mounting portion of the tine and in combination with a contoured clamp fastener, restrain the mounting portion of the tine in a predetermined position relative to the tine bar. The mounting base and clamp fastener further enable a plurality of tines to be easily and uniformly connected to a tine bar while the specific contours of the mounting base and clamp fastener in adjacent contact with the tine serve to reduce stress concentrations thereby promoting extended tine service life.
Claims19
A device for removably attaching a tine to a tine bar in a reel used on an agricultural machine, the tine bar having a plurality of through holes for receiving the device, the device comprising:
- a connector base having a first surface and a second surface, said first surface configured to match the tine bar exterior, said second surface being generally opposed to said first surface and having a receptacle configured to receive a portion of the tine;
- an aperture in said connector base extending from said first surface to said second surface;
- and
- an elongate connector having opposing first and second ends, said first end having a head with at least one clamping surface for contact with the tine and a retention shoulder that protrudes further from the head than the at least one clamping surface and shaped to seat within a retention structure within the connector base to prevent rotation of said connector , said second end spaced apart from said first end by a shank configured to extend through said aperture and be connectible to the tine bar whereby the tine may be connected to the tine bar.
A device for removably attaching a tine to a tine bar in a reel used on an agricultural machine comprising:
- an elongate tine bar arranged along an axis, said tine bar having a cross-section profile and a plurality of through holes spaced apart along said axis and oriented generally perpendicular to said axis;
- a tine having a mounting portion;
- a connector base having a first surface and a second surface, said first surface configured to match said tine bar cross-section profile, said second surface being generally opposed to said first surface and having a receptacle configured to receive said tine mounting portion;
- an aperture in said connector base extending from said first surface to said recess in said second surface;
- and;
- an elongate connector having opposing first and second ends, said first end having a head with at least one clamping surface for contact with the tine and a shoulder configured to engage said recess such that the shoulder is restrained by the walls of the recess to prevent rotation of the clamp fastener once inserted therein, said second end spaced apart from said first end apart from said first end by a shank configured to extend through said aperture and be connectible to the tine bar whereby the tine may be connected to the tine bar.
