A FORAGE HARVESTER EQUIPPED WITH A CROP PICK-UP HEADER

In a harvester/header combination according to the invention, the header is a crop pick-up header (2) coupled to a forage harvester (1). The header comprises a frame (10) and a rotatable reel (13) configured to collect crops from the ground, a rotatable auger (20) provided with two oppositely wound helicoidal flights (26), and one or more windguard rolls (15). The auger is rotatable with respect to a pair of support arms (21) which are themselves pivotable relative to the frame, so that the pivoting movement of the arms results in lowering or raising the auger (20). According to the invention, the header comprises at least one set of actuators (18.19) capable of actively raising the auger and the windguard roll(s) and the harvester/header combination comprises a control unit (46) configured to execute a sequence of steps for removing a foreign object from the header, after detection of the object and stoppage of the harvester's feed rolls (51). The removal sequence includes raising the auger while rotating the auger in the reverse direction, followed by lowering the auger while maintaining said reverse rotation.

An agricultural vehicle includes a chassis and a header carried by the chassis. The header includes: a header frame; a cutter movably coupled to the header frame; a reel arm pivotably coupled to the header frame; a reel carried by the reel arm and including a plurality of tines; a variable displacement fluid cylinder including an interior chamber, a first piston linked to the reel arm placed within the interior chamber and a second piston placed within the interior chamber, the interior chamber defining a shared volume between the first piston and the second piston; and a piston driver linked to the cutter and configured to translate movement of the cutter relative to the header frame into displacement of the second piston within the interior chamber.

CUTTING SYSTEM REDUCING CUTTING LOSSES AND HAVING A FLOATING DISK
20180035607 · 2018-02-08 ·

Decisive modifications are proposed to a cutting system reducing cutting losses and having a floating disk, in order to improve the efficiency of the system. The lower finger (1) cuts at the lower level and has a tip pointing upwards to prevent the finger from entering the ground; weeds passing past the lower finger pass over the upper finger (3), the accumulation of branches between the fingers being thus prevented. The upper finger (3) has a guard (4) that prevents grains from dropping out of the cutting platform, and the guard is also used to mount two bearings which act to orient the cutter bar (2).

Autonomous control of a crop harvesting header for detecting reel wrapping

A harvesting vehicle includes a header having a cutter bar, a crop transport draper and a reel mounted above the cutter bar to sweep the crop to the draper. The operation of the header is autonomously monitored and controlled to reduce operator loads or to run autonomously by detecting: reel wrapping; differential rates of flow of crop on the header at different locations; where the crop to be cut is at least partly lodged so that stems of the crop are not vertical; the presence of a crop streak of uncut or poorly cut crop behind the cutter bar and/or a band of disturbed soil behind the cutter bar. The detector is arranged to control ground speed, header height, reel height and operation.

A harvesting reel includes a reel frame and a rotating assembly. The reel frame includes two cam assemblies and a cover. The first cam assembly defines a first cam track, and the second cam assembly defines a second cam track. The rotating assembly carries a plurality of reel bats configured to revolve around the longitudinal axis of the rotating assembly and a plurality of reel tines fixed to each reel bat. Each reel bat is coupled to a first cam follower and a second cam follower. The first cam follower of each reel bat travels within the first cam track, the second cam follower of each reel bat travels within the second cam track, and a position and an orientation of each reel bat are defined by the cam tracks.
