Self-propelled agricultural harvesting machine having a crop attachment which is pivotable about a vertical axis

摘要

A self-propelled harvesting machine includes a chassis supported on driven front ground wheels and steerable rear ground wheels. A crop harvesting attachment is supported on steerable driven wheels and is mounted to the front of the harvesting machine for pivoting about an upright axis. The harvesting attachment delivers harvested crop to an intermediate conveyor which feeds the crop to an input conveyor of the harvesting machine. The harvesting attachment includes a power-operated steering actuator and is steered by a steering control device of the harvesting machine.

1. In a self-propelled agricultural harvesting machine (10) having a chassis (12), which is supported on means (14, 16) which are in contact with the ground and by way of which the harvesting machine (10) is movable over a field in a normal forward direction of travel (V), a steering control device (62) by way of which the means (14, 16) which are in contact with the ground are steerable, a harvested crop processing device (35) which is arranged within the chassis (12) and an input conveyer (36) which is arranged on the front end of the chassis (12), a crop attachment (20), which is mounted so as to be pivotable about a vertical axis in relation to the chassis (12) for the reception of harvested crop, being arranged upstream of said input conveyor, said harvested crop being delivered in the harvesting operation by the input conveyor (36) to the harvested crop processing device (35), wherein said crop attachment (20) being supported on the ground by drivable and steerable crop attachment ground contacting means (52, 76); a power-operated steering actuator (54) being coupled for effecting steering of said ground contacting means (52, 56); and said steering control device (62) being coupled to said steering actuator (54), wherein an elongated intermediate conveyor (34) is arranged between the crop attachment (20) and the input conveyor (36), wherein the crop attachment (20) Includes a left-hand segment (22), a right-hand segment (24) and a central segment (26) with means for the reception of the harvested crop, and having respectively arranged on their rear sides a left-hand conveyor (28), a right-hand conveyor (30) and a central conveyor (32) which transfer the received harvested crop in the harvesting operation to the intermediate conveyor (34) wherein the left-hand and right-hand segments (22, 24) have respective inner ends mounted for pivoting about vertical axes (64), whereby the left-hand segment (22) and right-hand segment (24) of the crop attachment (10) are mounted for movement into a folded-in transport position, in which the left-hand and right-hand segments (22, 24) are pivoted to the rear about the vertical axes (64) out of their operating position in opposition to the forward direction and are situated above the intermediate conveyor (34).
