20120152109 | FEEDER ARM SAFETY STAND - A safety stand for minimizing the effect of hydraulic failure in an agricultural harvester is disclosed. In one embodiment, a system for raising or lowering a pivotable safety stand is provided which may take the form of a remotely operated hydraulic safety stand. In another embodiment, the mechanical stop provides multiple stops along the length of travel of the piston to prevent the dramatic falling of the feeder arm under the force of gravity. In one embodiment, the safety stand is provided with a series of notches along a longitudinal edge of the safety stand which are designed to accept and received a protrusion affixed to a cylinder of a hydraulic cylinder which raises and lowers a feeder arm. When the feeder arm is raised, the hydraulic cylinder is in the full upright position, the safety stand can be lowered such that the protrusion enters and is held within a notch to prevent accidental downward movement of the feeder arm. If the notch fails, or the safety stand is not properly engaged, the longitudinal edge of the safety arm is allowed to follow the protrusion, until a subsequent notch is reached, which then engages the protrusion, safely stopping the downward path of the feeder arm. | 06-21-2012 |
20120202568 | KNIVES FOR ROTARY CHOPPER ASSEMBLY OF A COMBINE HARVESTER - 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. | 08-09-2012 |

20080256914 | Method and device for automatically coupling a combine feeder interface and a combine header via a stationary gearbox - An automatic coupling and latching assembly, for coupling a combine feeder and a combine header from the cab of a combine harvester, said assembly comprising a stationary gearbox with a telescopic jackshaft assembly extending therefrom, a shift fork activation unit, and comprising spring loaded retainers, is disclosed. | 10-23-2008 |
20080271425 | Apparatus and method for automatically coupling of electrical and hyraulic systems of a header of an agricultural harvesting machine - Apparatus and method for automatically coupling fluid systems and electrical systems, respectively, of a header and a feeder of an agricultural combine as the header is lifted by the feeder. The feeder and header include lifting elements pivotably engageable with lower portions of the feeder and header spaced apart, such that when the feeder is raised, the header will be lifted by the feeder and pivoted so as to bring the lower portions together. A first coupler block is supported on the feeder and includes at least one fluid coupler and at least one electrical contact, and a second coupler block is supported on the header and also includes at least one fluid coupler and at least one electrical contact. The fluid couplers and the electrical contacts are configured and positioned so as to couple and be brought into contact, respectively, as the lower portions of the feeder and the header are brought together. They can also automatically uncouple when the header is removed from the feeder. | 11-06-2008 |
20090048744 | Distribution leveling for an agricultural combine - A method and system for controlling distribution of crop material to a cleaning sieve of an agricultural combine, for reducing grain loss, including while the combine is tilted sidewardly relative to horizontal, involving controlling the angular orientation of a distributor disposed between a threshing system of the combine and the sieve, for distributing a mat of the crop material onto the sieve evenly across an extent thereof. The angular orientation of the distributor can be set in advance of tilting of the combine, to adjust for a variety of conditions, including uneven outputting of the crop material from the threshing system, and the set orientation can be automatically maintained or actively adjusted to control a desired operating parameter such as grain loss, even as the combine is variously tilted and the angular orientation of the sieve relative to the combine is independently adjusted to maintain the sieve horizontal. | 02-19-2009 |
20090197656 | Rigid rotor discharge deflector - A rigid rotor discharge deflector apparatus for a combine has a body member that is attachable to the side wall of a discharge passage at the downstream end of the rotor. The body has a face portion with at least one ridge portion thereon extending generally laterally across at least a portion of the face portion. The body also has an upper body portion above the level of the ridge portion, an upper ramp portion sloped and extending outwardly from the upper body portion to the ridge portion, and a bracing associated with the upper ramp portion maintaining the ridge portion essentially fixed relative to the side wall. The body member may also include a lower body portion below the level of the ridge portion, and the upper and lower body portions may both be attachable to the side wall. | 08-06-2009 |
