20200404849 · 2020-12-31 ·

A combine harvester includes a rotor cage surrounding a rotor, a threshing space defined between the rotor cage and the rotor, and a transition section defining an infeed to the rotor cage. The transition section is mounted to the rotor cage at a location upstream of the rotor cage. The transition section has an inlet for receiving the crop material. The harvester also includes a crop conveying drum for conveying crop material to the inlet of the transition section and beneath the rotor. The crop conveying drum is at least partially encased by a shroud. The transition section includes a bottom wall, two side walls each having lower portions extending substantially vertical with respect to the bottom wall, and curved side walls each extending between the bottom wall and one of the side walls. The bottom wall is substantially tangential to a Sower portion of the shroud.

A combine for harvesting chick peas includes a first rotatable shaft having components that cut a crop and pass the cut crop in a rearward direction, and a drum that includes an outer shell with stationary threshers and a cut crop opening, a rotatable central mount, a plurality of rotatable threshers. Each of the rotatable threshers is attached to the central rotatable mount and in line with a stationary thresher. A plurality of cutters is attached to the outer shell, a flame source projects a flame into the drum, and a water source projects water into the drum. The cut crop passes into the cut crop opening, to be further cut by the plurality of cutters and threshed by the plurality of rotatable threshers, such that the flame and water are projected onto the cut crop, resulting in a processed crop and detritus that is separated from the processed crop.

Bush hog cutting and threshing blade
10757858 · 2020-09-01 ·

A cutting and threshing blade for a bush hog, wherein the blade has a trailing edge and a leading edge. At least a third of the leading edge of the upper-side of an elongate distal portion of the blade has a knife edge with a knife length that thickens toward the trailing edge. The trailing edge can have an upward air deflector. The bottom-side of the elongate distal portion has a threshing element, which includes a threshing block, which is a steel block having a block length that is comparable to the knife length and projects downward and substantially parallel to the knife edge. The rotating blades pummel growth carriers (i.e.; cob, husk) bearing seeds, grains, and kernels with enough force that they are released. The synergistic rotating knife edge and threshing block transform the bush hogging process from a cutting process to a cutting and threshing process.

Adaptive control system for threshing separation load of tangential flow and longitudinal axial flow device

The invention provides an adaptive control system and a regulating method for the threshing separation load of the combined harvester and the longitudinal axis. The control system mainly comprises entrainment loss monitoring device, grain breaking rate monitoring device, device for regulating clearance of cutting concave outlet, jitter board load monitoring device, return plate load monitoring device and on-line monitoring and control system. According to the differential signal of the impact force sensor and the inertial force sensor, the cutting flow threshing and separating device is calculated by real-time monitoring of the grain breaking rate, the entrainment loss rate, the tangential groove outlet gap, the cutting drum speed and the longitudinal axis drum speed. And the ratio of the threshing separation load of the cut-off threshing separator and the longitudinal-axial-flow threshing and separating device is adjusted at a reasonable ratio range, to meet the difficult to take off, easy to off and other crops of different harvest requirements, to maintain the best threshing capacity and better adaptability.

Apparatus for separating plant flower from stalk and method of separating flower from stalk
10709070 · 2020-07-14 ·

An apparatus and method for separating plant flowers from stalks by means of a lateral rotating tube having a plurality of flexible, elongated members affixed to and extending radially outward from the tube. The apparatus may include a platform and a frame supporting the tube above the platform to accommodate plants held between the platform and the tube so that when the tube is rotating, the elongated members affixed thereto brush against the plants and cause the flowers to brush off at and separate from the stalks. The frame further supports a housing to form a contained space, including a back wall, side walls and a hood to direct the flow of flowers after separation from the stalks. The hood extends above and over the tube, having a front wall extending about or below a central axis of the tube. A power system provides rotational power to the tube.
