Abstract:
A method of making a rotor for a threshing system of an agricultural combine, the rotor including a main body segment made from a sheet formed into a tube and including specially shaped interlocking edges forming a serpentine joint routed locations where threshing element mounts attach to the rotor.
Abstract:
A grain tank includes a generally flat bottom that is oriented at a position that is less than the angle of repose of the grain. A conveyor mechanism conveys grain along the bottom to a cross auger for unloading. One or more sensors may be placed in the grain tank to determine a state of the grain to further determine if the conveyor mechanism should be operated to unload grain from the grain tank.
Abstract:
A support system for separator grates of a harvester includes a first member and a second member extending substantially parallel to an axis of rotation of a threshing rotor. The first member extends from a staging portion to a first support portion rearwardly positioned from the staging portion. The second member extends along a second support portion that corresponds to the first support portion. Separator grate segments may be selectably installed and removed from the first member and second member.
Abstract:
A rotor chopper assembly including a chopper rotor having a mounting lug. A knife blade includes a body having an opening arrangement configured to receive a retention device securing the body to a member that is rotatably connected to the mounting lug of the chopper rotor. During unobstructed operation of the rotor chopper assembly, the body is centrifugally urged radially outward from the mounting lug. In response to the body striking an obstruction during operation of the rotor chopper assembly, the body is urged into rotational movement until the retention device abuts a stop formed in the mounting lug. An angle subtended between axes defining unobstructed operation and stop abutment is different for at least two openings of the arrangement of openings formed in the body.
Abstract:
A rotary chopper element for an integral chopper assembly of a combine harvester, which rotary chopper element includes a cylindrical rotary member having a plurality of ring portions axially aligned in an ordered side-by-side arrangement along the longitudinal axis of the rotary member, with each ring portion having disposed annularly therearound a plurality of mounting lugs, each of which mounting lugs is designed to support or to have affixed thereto at least one knife blade. The mounting lugs on each succeeding ring portion are rotated or offset radially from the lugs of the preceding ring by a predefined amount and the knife blades are attached to the mounting lugs to form mounted assemblies that have beveled leading edges that extend substantially continuously from adjacent to the outer surface of the rotary member to the tips of the knife blades. The knife blades of such mounted assemblies define a plurality of spaced helical arrays that extend along and wrap around the rotary member. The rotary chopper element is configured to be mountable generally parallel to the grate portion of a counter knife assembly of the integral chopper assembly to define a material flow path between the grate portion and the rotary member and to be operable to transport crop residue past the integral chopper assembly.
Abstract:
A threshing element includes a structure having an outside surface for threshing a crop material, and an inside surface. A body is operatively connected to a sensor. The body is secured to the inside surface of the structure, the body having a connecting feature for securing at least the body and the structure to each other. The structure is securable to a rotatable threshing rotor of a harvester threshing system. In response to operation of the threshing rotor of the harvester threshing system, the sensor outputs a signal corresponding to forces generated by contact between the outside surface of the structure and the crop material.
Abstract:
A helical bar concave including a grate having helical mounting framework and helical cutouts to form a percent open area having a helical geometry. Configurable and segmented rub bars are mounted in a helical fashion to a cylindrical helical surface of the grate. The helical geometry in combination with configurable rub bars mounted in a helical fashion results in a configurable helical bar concave in which the number or aggressiveness of the threshing surface on the inside radius of the grate may be changed and/or the rub bars may be moved to the outside of the grate to change the percent open area and hence the separation characteristics of the concave.

Abstract:
A threshing system for an agricultural harvester including a plurality of threshing elements supported on a rotor at spaced intervals in a generally helical pattern about an outer surface of the rotor, each threshing element including a set of discrete threshing bars including a leading threshing bar proximate the outer surface of the rotor and a succession of threshing bars located progressively farther from the outer surface forming a ramp and defining a wedge shaped opening between the threshing bars and the outer surface, each set of threshing bars extending generally axially along the rotor defining axially extending spaces therebetween sufficiently large for passage of grain therethrough to the wedge shaped opening.
