An apparatus for use in combination with a combine for sensing the volume of tailings exhausted from a cleaning section of the combine and for providing a visual indication to the operator of the effectiveness of combine operation. The combine includes a mobile frame or chassis having an operator compartment arranged toward a forward end thereof. A threshing section of the combine separates grain from crop material delivered thereto. A cleaning section of the combine functions to remove chaff and tailings from the materials received from the threshing section. A tailings section of the combine is arranged to receive incompletely threshed and separated tailings from the cleaning section. The tailings section comprises a tailings conveyor for forcibly moving tailings toward an elevator that moves the tailings to one of the other sections on the combine for recycling. The sensing apparatus of the present invention is arranged proximate to the inlet to the tailings elevator and provides a visual indication in the cab region of the combine of the volume of tailings presented for recycling thus revealing the efficiency of the combine.
An agricultural combine having a frame, a threshing section provided on the frame to separate grain from crop materials delivered to said threshing section, a cleaning section in communication with the threshing section to remove chaff and the like from material received from the threshing section, and a tailings section wherein incompletely threshed and separated materials are received as tailings from the cleaning section, said tailings section comprising a tailings conveyor to convey the tailings toward an elevator that moves said tailings to one of said threshing and cleaning sections for recycling, said tailings section further including an apparatus to sense the volume of tailings in said tailings conveyor being directed to said elevator and a display responsive to said apparatus to provide an indication of the volume of said tailings being directed to said elevator.
A grain combine comprising a self-propelled chassis having an operator compartment, a threshing assembly provided on the chassis to thresh grain from crop, a sieve assembly in communication with the threshing assembly to separate chaff and tailings from threshed materials received from said threshing assembly, a tailings conveyor in communication with the sieve assembly to convey the tailings from the sieve assembly to a tailings elevator for recycling to one of the threshing assembly and the sieve assembly, an apparatus to measure the tailings being conveyed by said tailings conveyor, and a display arranged in the operator compartment and responsive to said apparatus to provide an indication of the measure of tailings being conveyed by the tailings conveyor and wherein the apparatus includes an actuator positioned to positively engage the tailings being conveyed by the tailings conveyor to the tailings elevator.
A self-propelled agricultural combine comprising a chassis, a grain cleaning and separating assembly mounted on the chassis to thresh crop material received by the combine, a cleaning system in material receiving relation relative to said grain cleaning and separating assembly to further separate grain from chaff and tailings, a tailings pan in communication with the cleaning system to receive the tailings from the cleaning system, an elongated auger mounted in combination with the tailings pan to convey said tailings to a grain rethreshing elevator operative to move the tailings received from said auger to a location for further cleaning and separating, an apparatus to sense the volume of tailings presented to said grain rethreshing elevator wherein the apparatus includes an actuator arranged proximate a peripheral edge of said auger prior to the grain rethreshing elevator, said actuator being displaceable from a predetermined position in response to the volume of tailings moving therepast, and a display responsive to the displacement of said actuator relative said predetermined position to provide a visual indication of the sensed volume of tailings and further including a flow-restrictive passage between the tailings pan and the grain rethreshing elevator, the passage having an infeed side and an outfeed side proximate the elevator, the apparatus being positioned proximate the infeed side of the flow-restrictive passage to sense the volume of tailings passing therethrough.
