20080295474 | CENTRAL AUGER CROP FEED SYSTEM FOR A HARVESTER - A header for a combine or harvester has a frame with a longitudinal dimension transverse to a direction of travel of the combine or harvester. Two moving belts are disposed on the frame to receive cut crop from a cutter and to move the crop from outer portions of the header towards an inner portion of the header. Each of the belts has a leading edge oriented towards the direction of travel of the combine or harvester and a trailing edge oriented away from the direction of travel and each of the belts has an inner aspect disclosed in spaced relation to an inner aspect of the other of the belts such as to define a gap therebetween, the gap receiving cut crop being transported longitudinally and inwardly from the belts. An auger with a cylinder and two end cones around an axis is disposed to urge crop from the gap and from the inner aspect of the belts towards a feeder house position behind the gap. The axis of the auger is forward of the trailing edge of the belt. A stationary floor plate beneath the gap is contoured to urge crop into the feeder house. | 12-04-2008 |
20080296131 | COMBINE HEADER BELT TENSIONING APPARATUS AND METHOD - A belt tensioning apparatus for a combine or harvester header has a frame with two spaced apart longitudinal support members and at least one transverse member attached to each of the longitudinal support members. An end roller support bracket has two bracket extensions extending longitudinally and disposed to slidingly engage with bracket extension receivers attached to the longitudinal support members. A push rod is longitudinally oriented and slidingly mounted on the transverse member intermediate to the longitudinal support members. The push rod is attached to the end roller support bracket and mounted to have a retracted position and an extended position. An actuator is attached to the longitudinal support members and exerts a substantially uniform force to the push rod along a range of travel of the push rod between the retracted position and the extended position. The actuator may be a scissors assembly or a hydraulic cylinder. | 12-04-2008 |
20100077712 | HEADER GROUND SENSOR - The invention is a combination of a short ground sensor arm mounted close to the cutter bar and a longer rod mounted towards the rear of the header. The short front sensor and long rear sensor are connected by a linkage which translates motions from either sensor to the other sensor. A second linkage translates the motions of both sensors rearward to a protected area under the header which contains the potentiometer. This configuration transmits useful ground position signals to the header height controller in both low and high cutting heights. The invention advantageously reduces the likelihood of damage to the short front sensor when the machine is reversed since the longer rear sensor arm pulls the shorter forward sensor arm up by means of the linkage to a position where damage is unlikely. | 04-01-2010 |
