Abstract: A transition device for a combine harvester includes a body having an inlet end and an outlet end. A plurality of vanes are positioned on an interior facing surface of the body for guiding crop material through the transition device. Each vane has a first end positioned either on or adjacent the inlet end of the body and a second end positioned either on or adjacent the outlet end of the body. An arc length between the first ends of two adjacent vanes of the plurality of vanes is less than or equal to an arc length between the second ends of the two adjacent vanes of the plurality of vanes, such that the crop material can expand between the two adjacent vanes upon travelling along a trajectory from the inlet end to the outlet end of the transition device.

Abstract: A root crop washer has a rotatable washing drum which is partially immersed in a water trough, and a stone separator mounted before an inlet of the drum. A loading hopper is provided for delivering a root crop to the stone separator. An elevator is mounted at an outlet of the washing drum for discharge of cleaned produce from an outlet of the washing drum. Rotating paddles within the stone separator impart a swirling motion about a vertical axis to water in the stone separator. The root crop is supported by the water and moved around an inner sidewall of the stone separator between an inlet and an outlet of the stone separator. At the same time unwanted heavier material such as stones and clay falls downwardly through the stone separator for discharge through a waste outlet at a bottom of the stone separator.

Abstract: Disclosed is a harvesting combine rotor cage top cover assembly that includes an overhead roof formed from a substantially horizontal flat section and downwardly angled side sections. A series of substantially parallel vanes are located beneath the overhead roof. Each vane is formed from a substantially flat top section located against the roof horizontal flat section and downwardly laterally extending legs being angled on their sides and having an arcuate bottom. The sides of the vanes are rotatable about a central pivot for promoting or retarding the flow of material in the rotor cage.

Abstract: A method comprising rotating a rotor to expel, radially, a mixture of grain and material other than grain (MOG) from the rotor and past a rotor cage encircling the rotor; causing an air flow in a substantially arcuate channel defined by the rotor cage, a first cover assembly covering a substantial portion of the rotor cage, and a passive sieve, to entrain a first portion of the MOG; capturing a first portion of the grain with the first cover assembly and plural vanes located along the length and on the interior surface of the first cover assembly, the captured grain sliding by gravity along the vanes to the passive sieve, the captured grain comprising threshed and unthreshed portions; enabling the passage of the captured grain through the passive sieve and into a second channel within which a grain conveying assembly is disposed; conveying with the grain conveying assembly the passed, unthreshed portion rearwardly; and conveying with the grain conveying assembly the passed, threshed portion forwardly.

Abstract: The invention provides an improved threshing and separating mechanism and method for a combine. The mechanism includes an elongated rotor mounted for rotation about a rotor axis within a rotor housing on the combine. The rotor has a threshing portion and a separating portion. The housing has a threshing section and a separating section corresponding to the threshing portion and the separating portion. The housing surrounds the rotor and is spaced from the rotor to form an annular space between the rotor and the housing for crop material to flow through in an axial crop flow direction from an inlet end of the housing to an outlet end of the housing. A rear portion of the rotor is tapered in a rearward direction to create an increased volume at the outlet of the rotor housing to prevent stagnation of flow of straw material in the transition of velocity between the housing outlet and the straw beater.

Abstract: A combine for cutting and threshing grain has an axial flow threshing drum. A feeder head mounts to the forward end of the threshing drum. Impellers on the feeder head push grain into the threshing drum housing and also provide threshing. Rasp bars on the feeder head thresh the crop prior to reaching the threshing drum while pushing the crop through perforations in the feeder housing. The feeder housing and threshing drum housing rotate, but at a slower speed than the threshing drum. A brake will prevent the threshing drum housing from rotating at an excessive speed. Clearances between the threshing drum and threshing drum housing, and clearances between the feeder head rasp bars and feeder housing, ca be adjusted for different crop conditions.

Abstract: A distinguishing feature of the threshing unit resides in its concave (4) being made up of a number of independent sections (5 and 6) arranged on both sides of the threshing cylinder rotor (1) longitudinal axis. The first section (5) of the concave (4), as along the direction of the cylinder rotation, is fixed rigidly with respect to the cylinder (1), while the other section (6) is articulated with respect to the first section (5) and has a device (7) for adjusting the outlet threshing clearance.

Abstract: An axial-flow combine with an improved rotor assembly which is configured to be less sensitive to crop material conditions. The rotor assembly includes a rotor casing with a rotor rotatably arranged therewithin. At its forward end, the rotor casing is provided with a transition section having a forward crop receiving end and an aft end. The rotor is provided with an impeller section which leads in a downstream direction to a threshing section. The impeller section of the rotor includes a plurality of impeller blades arranged within the transition section of the rotor assembly. A rearward end of each blade terminates upstream of the aft end of the transition section whereby allowing threshing instrumentalities on the threshing section of the rotor to extend into the transition section thereby extending the threshing area of the rotor thus enhancing crop material flow through the rotor assembly.
