Abstract: An apparatus and method is presented for separating healthy plants from agricultural material, such as harvested plants. The apparatus includes a conveyor to present the agricultural material to a mesh, which may be, for example bristles. A rotating drum with a plurality of protruding tines moves through the mesh and pulls individual plants from the agricultural material. A machine vision system may then sort the healthy, individual plants. The method includes presenting the agricultural material to the mesh, and then pulling individual plants through the mesh.

Abstract: A threshing mechanism is formed with a first threshing drum and a second threshing drum disposed one behind the other in a direction of crop flow. A first concave encloses the first threshing drum and the second threshing drum in sections in a circumferential direction. A second concave encloses the second threshing drum in sections in the circumferential direction. The concaves are displaceable in a radial direction of the threshing drums and are formed with at least one crop-processing device disposed at the first concave. The first concave and the second concave are swivellable about a common axis connecting the concaves. The enclosure of the second threshing drum by the first concave and the second concave is approximately identical.

Abstract: A combine harvester having a tubular housing that concentrically receives a rotor used for threshing and separating crop materials. Concave assemblies are arranged side-by-side along the a processing system. The processing system also includes at lease one disrupter plate placed between adjacent concave assemblies having an arcuate configuration similar to that of concave assemblies. An upper edge of the disrupter plate projects above the transverse bars and curved rods of the concave assemblies toward the rotor to slow the axial flow of the crop material through the rotor housing. Accordingly, the disrupter plate provides a tortuous flowpath for the crop material as it moves axially through the processing system to permit the more time for threshing and separation to take place.

Abstract: A mounting component for securing a crop handling element to a separator rotor is embodied as a profile-section component, with side walls facing toward one another and extending in some portions in the circumferential direction of the separator rotor; for securing the mounting component to the surface of the separator rotor, and each of the side walls of the mounting component has a longitudinal weld seam, extending essentially parallel to the side wall, with a weld seam portion extending beyond the length of the respective side wall, which weld seam portion is embodied at an angle to the respective side wall.

Abstract: An agricultural harvesting machine for removing and separating grain from harvested crop has a threshing zone and at least one separation zone for separating the grain. The axial separating rotor is at least partially encased by a separating housing having a plurality of sections. At least one of the sections is displaceable in the axial direction of the at least one axial separating rotor to increase the opening and ensure separation when a correspondingly large proportion of grain are in the outer region of the rotating crop stream and the proportion of admixtures is small.

Abstract: A rotary conveyor being disposed above the straw walkers of a combine is provided with a rotating body and disappearing tines. The rotary conveyor is an undershot conveyor and is designed to more aggressively loosen threshed crop material passing over the straw walkers. The tines are eccentrically supported in bearings. The tines can move radially in through tines guides that are located in recessed regions of the rotating body. The recessed regions being parallel to the transverse axis of the rotating body.

Abstract: A device for primary separation of grain and straw in a combine harvester for cereals, the combine comprising a chassis and wheels and, going from the front towards the rear relative to the longitudinal direction of combine displacement:a mower;a mown crop conveyor;a thresher; anda rotary drum separator;the separator further comprises:a rotary cylindrical drum disposed substantially horizontally in the longitudinal direction of the combine harvester and having an inlet orifice facing the thresher and an outlet orifice at the rear of the combine harvester;the drum comprising a cylindrical wall pierced by multiple perforations for passing grain, at least one internal rib fixed to the cylindrical wall and forming a helix at a first predetermined pitch extending over the entire length of the drum and a plurality of elongate drive members fixed around the drum and extending inwards, and disposed both longitudinally and circumferentially relative to the drum in such a manner as to form a set of successive portions

Abstract: A self-propelling field chopping machine comprises a chassis, a front cutting mechanism, a transporting channel provided with a throwing out pipe having a downstream end, a rotatable conveyor arranged upstream of the transporting channel and formed as a rotatable conveyor drum provided with paddels, a threshing device arranged between the cutting mechanism and the rotatable conveyor drum and operating in accordance with an axial flow system, a wind sieve device located at the end of the throwing pipe so that a grain-chaff mixture without straw is supplied to the wind sieve device, and a grain tank located under the wind sieve device.

Abstract: A rotary grain screener is disclosed in which the primary grain-advancing flighting is mounted on the internal surface of the rotary screener drum and an inner auger is mounted on a central axial drive shaft to advance the grain forward in the drum at a greater rate than is accomplished by the flighting on the internal surface of the drum. The screener drum is supported on the central drive shaft which has a support bearing on the input auger housing and the drum is further provided at the input end with two annular bearing plates which are attached to the end plate of the drum and have a close fit around the input auger housing for closure and support purposes. A single motive power source drives the drive assembly which operates both the input auger and the screener drum.
