Publication number: 20220046862Abstract: 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. The weed seed destructor is driven with a straw management system from an output shaft of the combine harvester so that the full power required for both passes through a belt which includes more than four longitudinally extending v-belt ribs and reinforcing cords located in a base band above the ribs at uniformly spaced positions across the width of the belt so that a replacement drive pulley on the output shaft has a width not significantly greater than a conventional output pulley which it replaces.Type: ApplicationFiled: July 28, 2021Publication date: February 17, 2022Inventor: Dean Mayerle

Patent number: 11202405Abstract: 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 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. A transfer auger at the rear edge of the combine sieve carries the weed seeds outwardly to respective weed seed destructors driven by the shaft of the transfer auger. The seeds are discharged radially through a discharge opening, where the angle of the discharge around the rotor axis can be changed to direct the seeds towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.Type: GrantFiled: January 28, 2019Date of Patent: December 21, 2021Inventor: Dean Mayerle

Publication number: 20210360851Abstract: A cutting blade for vegetation is provided for example for use in a straw chopper or rotary mower. The blade includes a first base material and a plurality of hard surface beads of at least two different materials formed on at least one surface of the base material extending up to a cutting edge of the base material wherein the plurality of hard surface beads lie alternately side by side with touching side edges and one contains at least one different material of a different hardness relative to the other so that differential wear rates are created, and a wear profile is controlled. The softer material is burnt away at the edge by the cladding laser to form pockets so that the blade is serrated by the pockets when supplied with additional wear increasing the pockets to maintain the serrations.Type: ApplicationFiled: August 10, 2021Publication date: November 25, 2021Inventor: Dean Mayerle

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.Type: GrantFiled: December 2, 2019Date of Patent: November 23, 2021Assignee: Tritana Intellectual Property Ltd.Inventor: Dean Mayerle

Patent number: 11013182Abstract: Discarded weed seeds in the chaff from the sieve of a combine harvester are destroyed by a weed seed destructor section which provides repeated high speed impacts caused by a pair of rotors each mounted in one of a pair of side by side housings which accelerate the discarded seeds onto a respective stator. A straw chopper and spreader section operate on the straw. The weed seed destructor and optionally the straw spreader is mounted so that it can be moved rearwardly away from the sieve to provide operator access between the destructor and the sieve.Type: GrantFiled: July 24, 2019Date of Patent: May 25, 2021Inventor: Dean Mayerle
