  • Patent number: 10405493
    Abstract: A residue handling system of an agricultural harvester includes a straw beater for receiving material other than grain from a threshing and separating system. A subsequent residue treatment device receives the material from the straw beater and breaks down larger parts of the material prior to discharge from the agricultural harvester. At least one wind generating system is located at an end of the straw beater and directs a flow of air from the vicinity of the straw beater to the subsequent residue treatment device. The flow of air is directed to pass substantially through an upper rearward part of the residue handling system. The flow of air operates to further entrain, render airborne, and transport material other than grain proceeding from the straw beater to the subsequent residue treatment device.

    Abstract: A residue handling system for an agricultural combine including a residue chopper that provides enhanced air flow for evenly distributing crop materials onto a crop field. A hub and blade assembly accurately positions flail blades and resists fatigue stresses. Each flail blade includes an outer portion that is angled longitudinally away from a plane transverse to the axis of rotation. In a mated blade pair embodiment, the leading edges of the paired flail blades may be closer to each other than the trailing edges, or vice versa. Also, the leading edges of the flail blade pair may be the same distance away as the trailing edges of the pair, beneficially directing discharge sideways in a preferred common direction. The assembly includes a mounting support post that has a width substantially equal to the distance between two mated blades. The mated blades are installed directly against the sides of the mounting support, without spacer bushings, using only three connector elements.

  • Patent number: 5976012
    Abstract: A forage harvester is provided with a front unit, comprising a rotatable cutterhead to which crop material is fed by feeding apparatus comprising stationary lower feedrolls and movable upper feedrolls. The upper feedrolls are suspended from the feeder frame by a pair of belts, which define the lowermost position of the movable feedrolls, under conditions where no or very little crop is introduced into the harvester. Inevitable accumulation of crop material or dirt on the components of the feeding apparatus will not influence the position to which the feedrolls may be lowered. A steady and even flow of crop material to the cutterhead can hence be maintained, even when little material is introduced.

  • Patent number: 5928080
    Abstract: The object of the invention is a straw-cutting machine which is positioned behind the grain separation devices of a combine harvester and whose separation organs chop the stalks falling from the straw walkers into short pieces. The aim of the invention is by means of a special design of the separation organs to reduce the required driving power, to chop and disintegrate stalks falling onto the straw-cutting machine in a lateral position or a longitudinal direction uniformly into the smallest possible pieces and subsequently to disperse the chopped stalks as uniformly as possible over the whole cutting width on the soil. This is achieved by positioning in uniform distribution fixed tang plates serrated on their front sides on the mantle of a chopping cylinder which tang plates separate laterally positioned stalks in a drawing cut in a uniform, relatively thin veil over cutting knives fixed rigidly, but equipped with springs on the chopping floor.

  • Patent number: 5775991
    Abstract: A straw discharge assembly allows the beater to reach further towards the rotational axis of the threshing rotor, thus enabling it to remove a greater percentage of the straw which otherwise collects on the housing frame members. The beater has a barrel-shaped body, but it takes on an hourglass shape as it is divided into a center section with shorter blades and two side sections with longer blades, giving the center section a smaller effective diameter than the two side sections. The beater does not interfere with the rotational path of the rotor housing frame even though it is effectively closer to the housing frame. With their longer blades, the side sections are closer to the rotating frame legs and can therefore pull down and discharge more of the obstructed straw. The discharge grate is conformed to the effective shape of the rotor in a similar fashion.
