Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor which accelerates the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The destructor is mounted on or coaxially with a suitable drive shaft in the straw stream such as the chopper rotor shaft. The rotor is mounted on bearings relative to the chopper rotor drive shaft and is coupled thereto by a releasable coupling between plates radial to the shaft so that the rotor can be stopped while the chopper rotor continues to operate in the event of a fault in the weed seed destructor.

A combine harvester includes a straw discharge rotor discharging into a straw stream and a sieve discharging into a chaff stream and a weed seed destructor section receiving the chaff and weed seeds for devitalizing at least some weed seeds. The straw is maintained out of the chaff stream by a guide construction having a front curved section underneath the rotor and a rear section which comprises a row of cantilevered flexible fingers which flex to assist in flow of the straw thereover and release of the straw from the rear end thereof. The rear ends of the fingers are thus unconnected and allow the straw to be freely released onto a dividing wall extending to the entrance to a straw chopper. The row of fingers can be carried on a support bar which is reciprocated around a transverse axis by a connection to a reciprocating element of the combine.

A combine harvester includes a straw chopper, spreading device and a weed seed destructor (WSD) which acts on the weed seeds in the chaff so as to cause devitalization. The WSD includes a discharge mouth where the WSD causes generation of an air flow which exits through the mouth. The system is operable in two modes where in both the straw is directed to the straw spreading device. In the first mode the chaff is directed into the WSD and in the second mode the chaff is carried past the WSD on a guide surface and is converged inwardly to drop into the air stream from the WSD. In both modes the chaff is spread using the air stream from the WSD at least to the sides either by feeding to the spreading device or by combining with the stream of straw after it leaves the spreading device.

A residue management system of a combine harvester includes a tailboard with a guide surface and guide fins for spreading of the residue to the sides. At least one of the fins includes a leading portion which is smoothly concavely curved up to a trailing portion which intersects with the leading portion at a change in direction or defined bend in the sheet metal. The trailing portion thus extends across and intersects with a path of the residue as it passes along the concave side surface at the leading portion and leaves the end of the leading portion to apply increased pressure on the stream and thus increase the spreading action. The trailing edge of the trailing portion is also inclined to a line across the trailing portion at right angles to the tailboard surface which causes the residue to leave the trailing edge at different angles.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which has inner and outer rings of rotor bars which accelerate the discarded seeds into contact with inner and outer rings of stator bars at angularly spaced positions around the axis of the rotor. The rotor bars of the outer ring have an increased resistance to wear relative to those of the inner ring and the stator bars of the outer ring have an increased resistance to wear relative to those of the inner ring. The stator bars are U-shaped in cross-section to form first and second legs which are symmetrical and therefore reversible when the second leg is worn for extended life.

U-shaped bars are symmetrical and can be reversed when the second leg is worn for extended life. Parts of the rotor and stator which are radially outward of other parts are formed with a higher resistance to wear approximately proportional to the radius so that the wear characteristics of the different parts are matched to the velocity of the particles impacting the different portions to generate symmetrical wear throughout the structure.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.

A chopper for receiving the straw and/or chaff from a combine harvester includes a housing with a chopping rotor to transport the materials though a discharge opening onto a tailboard construction with downwardly facing guide surface and fins for spreading of the crop materials. A rotary spreader has a plurality of fan members with blades rotatable for discharge to a respective side of the rotary spreader. An arrangement is operable so that in a first mode the crop material is spread wholly by the tailboard and in a second mode the crop material is spread at least mainly by the rotary spreader. In the second mode the tailboard remains position above the rotary spreader which is therefore located underneath a guide surface with fins of the guide surface facing downwardly adjacent the blades. The movement to the second ode is provided by the rotary spreader being moved forwardly and downwardly.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts in a destructor mill. The combine includes a separation arranged to direct straw into a first material stream and chaff and weed seeds into a second material stream, A guide component downstream of the separation directs the straw into a spreading system and the chaff into the destructor mill where at or adjacent a leading edge of the guide component is an active component in the form of a roller movable to ensure the first material comprising straw does not remain on the leading edge of the guide component.

38 ABSTRACT Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.

A chopper for receiving the straw and/or chaff from a combine harvester includes a housing with a chopping rotor to transport the materials though a discharge opening onto a tailboard construction with downwardly facing guide surface and fins for spreading of the crop materials. A rotary spreader has a plurality of fan members with blades rotatable for discharge to a respective side of the rotary spreader. An arrangement is operable so that in a first mode the crop material is spread wholly by the tailboard and in a second mode the crop material is spread at least mainly by the rotary spreader. In the second mode the tailboard remains position above the rotary spreader which is therefore located underneath a guide surface with fins of the guide surface facing downwardly adjacent the blades. The movement to the second ode is provided by the rotary spreader being moved forwardly and downwardly.
