专利汇可以提供Row crop harvester attachment专利检索，专利查询，专利分析的服务。并且A three-row row crop harvesting attachment for a forage harvester has three generally fore-and-aft passages which receive three rows of row-planted crops as the machine advances, a cutting apparatus being provided at the forward end of each passage for severing the crop from the field. A pair of gathering devices are disposed along opposite sides of each passageway and move the stalks upwardly and rearwardly to the crop inlet on the forage harvester. Each gathering device includes an endless chain trained around front and rear sprockets and having belt-like loops which extend into the passageway and intermesh with the loops in the opposite gathering device to grasp the stalks of the crop, the rear sprockets for the center pair of gathering devices being disposed above the level of and forwardly of the other rear sprockets. A pair of rollers extend upwardly from the rearward end of the fenders overlying the outer two gathering devices and are respectively coaxially connected to the outer rear sprockets, so that the inner peripheries of the rollers engage the crop in the outer two passageways to assist in the convergence of the crop into the inlet opening. A pair of generally horizontal forwardly diverging arms extend forwardly from the upper ends of the rollers to guide the upper portions of the stalks.，下面是Row crop harvester attachment专利的具体信息内容。

权利要求

1. In a harvesting machine having a mobile body adapted to advance over a field of row-planted crops and provided with a forward crop inlet with generally upright opposite sides, the combination therewith of an improved multi-row crop harvesting attachment comprising: at least four generally fore-and-aft, downwardly and forwardly inclined gathering members, each gathering member including a fender presenting a smooth upper surface on top of the gathering member and a forward gathering point adapted to ride along the ground between the crop rows; at least three generally fore-and-aft, upwardly and rearwardly inclined passageways respectively formed between adjacent gathering members and adapted to receive the crop growing in a row as the machine advances; means adjacent the forward end of each passageway for severing the crop from the field; a pair of gathering conveyors respectively disposed on opposite sides of each passageway for engaging the crop therein and moving the severed crop to the crop inlet, each gathering conveyor including a front sprocket mounted on the gathering member adjacent the passageway, a rear sprocket mounted on said gathering member adjacent to and forwardly of the crop inlet, and an endless, flexible element trained around the front and rear sprockets; a pair of approximately upright rollers disposed above the rear sprockets of the outer two gathering conveyors and extending upwardly from the rearward ends of the fenders on the outer two gathering members, the inner sides of the rollers extending into the outer two passageways and being disposed generally in foreand-aft alignment with the opposite sides of the inlet; and drive means for rotating the rear sprockets and the rollers so that the inner sides of the rollers move rearwardly and converge the crop into the crop inlet and the inner runs of the gathering conveyor move rearwardly along opposite sides of the respective passageways, the drive means including a pair of generally vertical shafts respectively coaxially connected to the outer rear sprockets and to the respective rollers.

2. The invention defined in claim 1 including a pair of upright members extending upwardly from the rearward ends of the outer two gathering members, and an upper stalk control extending forwardly from the upright members and including a pair of forwardly diverging arms, the rollers being disposed immediately in front of the upright members with the upper ends of the rollers being supported in the upper stalk control.

3. The invention defined in claim 2 wherein the drive means includes a first transverse input shAft, a second transverse shaft parallel to and driven by the input shaft, bevel gear means respectively connecting the second transverse shaft to the opposite generally upright drive shafts, means including bevel gear means connecting the input shaft to the rear sprockets of the central gathering conveyors, and means including bevel gear means connecting the second transverse shaft to the rear sprockets of the inner gathering conveyors along the outer two passageways.
