Abstract:
An apparatus and method for distributing crop material onto a cleaning sieve of an agricultural combine. The method includes providing at least one sensor configured and operable for sensing information representative of at least one of a quantity of grain associated with the crop material distributor and an inclination angle associated with the crop material distributor, and outputting signals representative thereof. The method includes providing a crop material distributor disposed between a threshing system of the combine and the sieve, for distributing crop material from the threshing system generally evenly onto the sieve. The method includes providing an apparatus operably associated with the distributor for controllably distributing crop material onto the sieve. The method includes controlling a position of the apparatus as a function of signals from the at least one sensor.
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 biomass conveying and distributing system for separating and distributing lighter biomass residue from heavier or denser biomass, utilizing available air flow from the cleaning system of the harvester. The harvester will discharge a flow of heavier or denser biomass with an airborne flow of lighter biomass residue. The system includes a conveyor for receiving and conveying the heavier or denser biomass, and residue distributing apparatus disposed above the conveyor in a path of at least a portion of the airborne flow of lighter residue, including at least one deflector configured and operable for redirecting the airborne flow sidewardly away from the conveyor, above a passage through which the conveyor passes carrying the heavier biomass away from the harvester.
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:
The bulk materials cart has a dual unload system including at least two inclined belt conveyors bounding an enclosed cavity. A first belt conveyor is operable for conveying bulk materials from the cavity to an unloading conveyor extendable from that side of the cart. A second belt conveyor is operable for conveying bulk materials upwardly and over another side of the cart. The dual unload system is automatically operable in a first mode operating the first belt conveyor and the unloading conveyor for conveying the bulk materials away from the cart, and in a second mode operating the second belt conveyor for conveying the bulk materials over the side of the cart.
Abstract:
An agricultural combine unloader extension is provided that can be used to extend the reach of conventional unloader tubes and for preventing the loss of crop material residing within the unloader tube from falling out and becoming waste. The unloader extension is hingedly connected to the unloader tube and configured to be moved from a discharging position to a closed or storage position.
Abstract:
The cob cleaning conveyor system provides a capability for positively removing or cleaning lighter crop residue from a flow of cobs. The system can be incorporated with a cob collection device, such as on a trailer, and can be adjustable in several ways for accommodating varying corn varieties, conditions and the like. The system includes a first conveyor which propels the flow into a gap or passage toward a second conveyor, while a flow of air is directed downwardly through the passage to remove or clean the lighter residue material from the cobs. The angle of attack of the air flow can be selectable, and optionally be directed downwardly along the second conveyor to the passage, and upwardly along the second conveyor to travel with or follow the residue flow, to suit present conditions.
Abstract:
An unloading system for an agricultural harvesting machine for reducing grain loss by detaining a grain saver door after movement to a fully open position during the unloading process, and by rapidly returning the door to a closed position with sufficient force for urging grain in the door area back into an unloading tube a predetermined time after the unloading process pauses or ceases. The system can advantageously detain the door in the open position in the presence of varying or reduced amounts of grain for increasing consistency and cohesiveness in the flow discharging grain and reduce the amount of grain remaining near a discharge end of the unloading tube when the door is in the closed position.
Abstract:
A cleaning system for corn cobs incorporating a conveyor system providing a capability for positively removing or cleaning other crop residue from the cobs, which is adapted to be towed by a harvester; to be incorporated with a cob collecting device; and which can be adjustable for varying corn varieties, conditions and the like. The conveyor system includes at least one enclosed inclined conveyor for carrying a flow of the crop residue upwardly and propelling the flow into a space, while a flow of air is directed downwardly along the conveyor to remove other residue material from the cobs. Another flow of air is optionally directed downwardly through the space for removing additional material other than cobs, and at least one aspect of the system can be adjusted for relatively varying the air flows to adapt the system for a variety of conditions.
Abstract:
A conveyor system for receiving corn cobs with husks still attached thereto after harvesting of the corn from the cobs, and detaching the husks from the cobs, including a conveyor inclined at an angle of at least about 30 degrees and bounding a passage for receiving a flow of the cobs including the husks attached thereto, the conveyor including apparatus configured and operable for mechanically grasping and detaching the husks from the cobs and pulling the detached husks through the conveyor, and at least one blower configured and operable for urging the husks within the passage toward the apparatus. The conveyor system can be provided in connection with a cob collection device, such as on a trailer to be towed by a harvester. The conveyor system can also include an additional conveyor or conveyors, optionally including apparatus for removing or cleaning crop residue from the cobs.
