摘要： A combine of the axial flow type having an axially extending power driven rotor which coacts with a concave complementary in shape to that of the rotor to thresh a wide variety of agricultural crop material. The concave comprises a plurality of longitudinal bars that are spaced transversely and a first row of curved wires extend through said bars adjacent the upper edges thereof and are spaced even distances in a longitudinal direction to form passages for threshed crop material. A second row of wires extend through a row of holes in said bars below said first row of wires. The second row of wires is spaced more closely than the wires of the first row to form pockets which receive said threshed crop material and remove the same from contact by said rotor to prevent damage to the threshed material and also provide more aggressive threshing of the material.

摘要： A multi-row crop header for a harvesting machine has a plurality of fore-and-aft extending row crop units, each having an elongated passageway with a front inlet opening and a rear discharge opening. The row crop units are pivotally mounted such that they can be swung toward and away from one another so as to vary the lateral distance between the inlet openings of adjacent units to thereby accommodate crops planted in various width row spacings.
