Harvester for rice, wheat and similar cereals

Abstract

A harvester-thresher has a frame adapted to be pulled along the ground and formed with a forwardly-opening slot which is flanked by a pair of flailing elements that are displaced back and forth relative to this slot without cutting or pulling up this crop in order to thresh grain or the like from a crop passing upwardly through the slot. The flailing elements can be a pair of vibratorily reciprocal elements operated by a crank arrangement. It is also possible to use a pair of rotatable supports which each carry a pair of polygonal-section rollers that are orbited next to the slot and are themselves rotated about their own axes to flail the grain off the crops. The two assemblies are interconnected by a pair of gears and the individual rollers are themselves rotated by means of a V-belt or an internal gear connected to the ends of these rollers.
