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 into contact with stator bars at angularly spaced positions around the axis of the rotor. The stator bars are formed from bent sheet metal which are L-shaped or U-shaped in cross-section to define a first leg lying in a cylindrical surface surrounding the axis of the rotor and a second leg extending outwardly from the cylindrical surface connected to the first leg at an apex at a leading end of the first leg relative to the direction of rotation of the rotor. When U-shaped, the bars are symmetrical and can be reversed when the second leg is worn for extended life.

An agricultural harvester includes a chassis and a residue handling system carried by the chassis. The residue handling system includes a set of rotating knives disposed in a housing, a first set of counter-knives, and a residue pivoting platform and/or a second set of counter-knives. Crop residue travels through the system in a residue flow direction. The first set of counter-knives are configured to enter the housing proximate to the set of rotating knives. The residue pivoting platform is positioned proximate to the first set of counter-knives in an upstream direction relative to the crop residue flow direction. The second set of counter-knives are configured to enter the housing proximate to the set of rotating knives. The second set of counter-knives are in a downstream direction relative to the crop residue flow from at least one of the residue pivoting platform and the first set of counter-knives.

The invention provides a longitudinal shunt combine machine for drafting and crushing and self-adaptive spraying device and a control method, including a longitudinal axis flow drafting and drainage device, a stalk miscible shredding device, a wind direction wind speed detecting device, a partition identification device, walker, crushing speed sensor, adjustable width throwing device, adaptive throw real-time control system. The width of the throwing can be adjusted according to the speed of the machine, the speed of the wind, the wind speed, the wind direction, the cut area, the position of the area to be adjusted, so that the full width and width of the stalk residue can be scattered evenly in the field avoid broken pieces of straw flinging to the area to be cut. The longitudinal axis flow drainage guide is installed in the guide plate and the shunt bar, so that the crushing load is relatively uniform, at the same time to solve the longitudinal axis flow threshing roller caused by an excessive row of grass is not smooth, blocking and other issues.

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 procedure for collection and processing of weed seeds of the type which includes: a first step of collecting of a plant material; fourth step of threshing of the harvested material; a fifth step of separating of grains from material other than the grains; a sixth step of cleaning of the main material; a seventh step of transporting the main material to a discharge device; and an eighth step of storing the main material in an appropriate media. Also includes a second step of placing the material obtained by a thresher head assembly into at least one conveyor belt towards a trailer; a third step of transferring the plant material into a transport and hauling vehicle to a stationary processing plant; a ninth step of grinding the residues; a tenth step of introducing the MDG into densification device; and a tenth step of incorporating in a mixer the resulting grinding of the ninth step along with at least one supplement.
