Patent number: 6712691Abstract: A harvesting unit for graff (a mixture including grain, chaff and weed seeds). The unit includes a wheeled harvester body and a harvesting header. A threshing unit is provided to separate stalks from graff and a tank is provided for storing the graff. The tank has a rear well and a floor provided with a elements that move the graff to the well. A graff collection bed is provided beneath the threshing unit and has a transverse collection trough. Augers in the trough move the graff laterally and graff elevators lift on each side of the storage tank lift the graff to the storage tank.Type: GrantFiled: June 4, 2002Date of Patent: March 30, 2004Assignee: McLeod Harvest Inc.Inventor: Robert H. McLeod

Patent number: 6709329Abstract: A method and system of harvesting crops involves cutting and threshing the crop, separating graff from straw, and returning the straw to the field. This is carried out in a harvesting unit of the pull type having a graff storage tank. The collected graff is moved to a stationary cleaning mill in a different location by means of a suitable vehicle such as a truck. Storage of the graff prior to cleaning is avoided and the cleaning mill, and the harvesting unit and vehicle.Type: GrantFiled: June 4, 2002Date of Patent: March 23, 2004Assignee: Mcleod Harvest Inc.Inventors: Robert H. McLeod, Wilfried Oswald

Publication number: 20030022706Abstract: A method and system of harvesting crops involves cutting and threshing the crop, separating graff (a mixture of grain kernels, chaff, weed seeds, and other organic matter) from straw (plant stalks), and returning the straw to the field. This is preferably carried out in a harvesting unit of the pull type having a graff storage tank. The collected graff is moved to a stationary cleaning mill in a different location by means of a suitable vehicle such as a truck. Storage of the graff prior to cleaning is avoided and the cleaning mill, and preferably the harvesting unit and vehicle, are designed to make this possible. This avoids difficulties caused by the poor material flow of graff. Various details of the equipment are also novel.Type: ApplicationFiled: June 4, 2002Publication date: January 30, 2003Inventor: Robert H. McLeod

Patent number: 5380247Abstract: A combine has a conveyor for returning clean grain and grain returns to a grain bin and threshing rotor, respectively, using a single conveyor housing which is divided by a partition into separate clean grain and grain returns compartments. A plurality of paddles are mounted within the compartments and are driven by a flexible linkage which extends around the frame of the combine within the conveyor housing. The grain bin is pivotally mounted along a pivot axis which allows the grain bin to be pivoted toward an opening of the grain bin to facilitate the flow of grain from the grain bin to an unloader for discharging the grain from the combine.Type: GrantFiled: June 21, 1993Date of Patent: January 10, 1995Assignee: Agri-TechnologyInventor: Mark R. Underwood
