Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

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 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.

Abstract

Weed seeds are destroyed in the chaff from a combine harvester by repeated high-speed impacts in a weed seed destructor section caused by a rotor mounted in one of a pair of side-by-side housings which accelerate the material in a direction centrifugally away from the rotor onto a stator. The destructor section is mounted for movement in a direction rearwardly of the combine harvester from an operating position at the second material discharge location to an access position retracted from the rear of the sieve with the access position being arranged to allow access of an operator to a position between the destructor section and the sieve. The destructor section is mounted in combination with the straw chopper/spreader holding the weed seed destructor section supported relative to the combine harvester in both the operating position and the access position.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

A straw chopper is mounted at the rear hood of a combine harvester and includes a housing with a feed opening and a discharge opening and a rotor mounted in the housing comprising a hub with a plurality of blades mounted on the hub for chopping the fed materials and accelerating the chopped materials for discharge. A tailboard has a plurality of guide fins arranged relative to the housing so as to receive the chopped materials from the discharge opening to engage onto a guide surface and guide fins of the tailboard construction for spreading of the chopped materials to the sides. On each side of the tailboard an outermost one of the guide fins has a first fin portion extending downwardly from the bottom surface to an lowermost edge, a second fin portion inclined from the lowermost edge downwardly and toward the contact side of the fin and a third fin portion inclined from the second portion to the concave side and toward the bottom surface.
