Abstract
An axial flow combine having a crop harvesting header including a feeder for cutting a crop and feeding it rearwardly into a threshing and separating mechanism. The mechanism includes a casing for receiving the crop material and a rotor within the casing for threshing and separating grain from the crop material. A plurality of crop material directing vanes is disposed within the casing and cooperate with the rotor in directing the material generally helically along the casing. Means are included for selectively and simultaneously adjusting the position of the vanes to change the rate of movement of the crop material through the casing.
Claims7
In an axial flow combine, the combination comprising:
- a generally cylindrical rotor casing having an open end for reception of crop material to be threshed and separated;
- a generally cylindrical rotor journalled for rotation within said casing and having a plurality of rasp bars secured thereon for threshing crop material;
- a plurality of crop transport vanes disposed within said casing in radially spaced relation to the rasp bars on said rotor for coacting with said bars upon rotation of said rotor to direct the crop material generally helically along said casing;
- and means for simultaneously adjusting the positions of said vanes relative to the casing to selectively vary the rate of movement of the crop material through said casing.
