US 2019/0335664 A1 · Single Disk Rotary Forage Harvester Header

Abstract

A non-row sensitive forage harvester header is formed with a single rotary member driven by a simplified drive mechanism coupled to the primary drive of the forage harvester to which the header is mounted. A horizontal drive shaft transfers the rotational power laterally to a gear box. The vertical output shaft from the gearbox has a first drive sprocket mounted thereon to connect directly with a drive chain fixed to the crop transfer disks, and a second drive sprocket mounted thereon and coupled to a drive chain entrained around a driven sprocket on the cutting disk to provide a drive speed differential with respect to the crop transfer disks. The crop guides are formed with rearwardly angled transfer arms cooperable with sweeper members on the crop transfer disk to direct the severed crop into engagement with the transfer disks for feeding into the forage harvester.

Dependent claims

A non-row sensitive forage harvester header, comprising:

a frame;
a single rotary cutting member rotatably driven to sever standing crop material from the ground and to convey the severed crop material rearwardly along a flow path, said single rotary cutting member including a cutting disk rotatable about an axis of rotation and operable to sever the standing crop material and at least one crop transfer disk rotatable about said axis of rotation to transfer the severed crop material around the periphery of said single rotary cutting member for discharge from said forage harvester header;
and
a drive apparatus supported on said frame and including a first drive mechanism operably connected to said at least one crop transfer disk and a second drive mechanism operably connected to said cutting disk.
