Abstract

Attachments for broadcast combines which have been converted into row type combines, in which the bearing guard attachment shields the shaft bearing on the lower ends of the drum shafts from becoming covered with vegetation which wraps therearound during the harvesting operation. The vegetation wrapped around the shaft bearing and the lower ends of the shafts precludes free circulation of air which cools the bearings and prevents the loss of lubricant therefrom due to expansion of the lubricant resulting in leakage from the elastomer seals. Rearwardly inclined pans positioned on the combine so as to be between the crop rows, each having angularly diverging upstanding walled sides for a portion of the length of the forward ends, which walled sides connect with upstanding walled sides along each lateral side of each pan to define a passageway for the crop being harvested to pass through, with the pans, having open rear ends to catch the shattered seed or grain and to direct same downwardly onto the conveyor and into the thresher of the combine.

Dependent claims

An attachment for a broadcast type combine having a sickle, which combine has a row harvester attachment thereon, which row harvester attachment includes an elongated transverse frame, braces forming support members extending downwardly from the elongated transverse frame at spaced intervals therealong so as to be between the rows of the crop being harvested, a further support member secured to the lower end of each downwardly depending brace support member and extending laterally therefrom, an apertured transverse member mounted near the outer end of each said further support member and extending therefrom, the transverse member being apertured near the outer ends thereof, spaced apart bearings mounted on the elongated row harvester frame and mounting the upper ends of the spaced apart upright shafts, bearings mounted on the apertured transverse member and mounting the lower ends of the upright, spaced apart shafts, a rotatable drum mounted on and secured to each upright shaft, each drum having fingers mounted thereon in circumferentially and longitudinally spaced apart, timed relation, and extending outwardly therefrom to urge the crop being harvested against the sickle of the combine, which attachment comprises;

a. a partly cylindrical collar mounted on each said lower bearing and extending upwardly substantially from the apertured transverse member into closely spaced relation with the lower end of each drum,
1. the closed side of each guard collar being adjacent the row of the crop being harvested so as to permit free circulation of air through the bottom and the open side portion of each partly cylindrical bearing guard collar.

an adjustable member connected between the forward end of each pan and

the elongated frame of the harvester attachment to support said pans. 6. An attachment for a broadcast type combine having a sickle, which combine has a row harvester attachment thereon, which row harvester attachment includes an elongated transverse frame, spaced apart bearings mounted on the elongated row harvester frame to receive the upper ends of the spaced apart, upright shafts, bearings mounted on the row harvester attachment to receive the lower ends of the upright, spaced apart shafts, a rotatable drum mounted on and secured to each upright shaft, each drum having fingers mounted thereon in circumferentially and longitudinally spaced apart timed relation and extending downwardly therefrom to urge the crop being harvested against the sickle of the combine, which attachment comprises;
a. at least a pair of pans mounted on and secured to the sickle unit of the combine,
1. each said pan having an upright wall around the transverse sides and the forward end portion,
2. each said pan having an open rear end from which seed is directed onto the apron of the combine,
3. the forward end of each pan, adjacent the crop row, being angulated toward the row to direct the crop being harvested inwardly,
4. the pans of each pair defining a passageway therebetween, which passageway is in close proximity to a row of the crop being harvested, so the spaced apart, rotatable drums will direct the crop being harvested into the passageway onto the conveyor, with the shattered seed falling from the crop being directed into the pans and onto the conveyor of the combine,
5. the forward end portion of each pan being elevated,
6. an adjustable member connected between the forward end of each pan and the elongated frame of the harvester attachment to support said pans.
