  • Patent number: 6050894
    Abstract: An impeller blade for the rotor of an axial flow combine harvester is shaped such that an outer blade portion has a shape of the blade portion defining an inclined edge which joins a forward blade edge lying in a radial plane of the rotor at a first position spaced outwardly from the hub of the rotor and joins the outer blade edge at a second position spaced rearwardly of the first position, the inclined edge having at least a part thereof which is substantially straight and parallel to an inner blade edge so as to be inclined at an angle to the outer blade edge and extend outwardly and rearwardly from the first position to the second position such that the radial distance of the second position from the axis is greater than that of the first position. This reduces the length of the forward edge to 50% to 75% of its conventional length and acts to overcome a long standing feeding problem of this type of rotor in some crops.

  • Patent number: 5980383
    Abstract: An attachment for an auger of a harvesting machine reduces or essentially eliminates residue build-up on the auger of the harvesting machine. The attachment includes a paddle, which is adapted to be secured to the auger between the flighting of the auger, and at least one projecting member which extends from the paddle and projects above the flighting of the auger for breaking up crop residue which tends to build up above the auger. The projecting member is secured to the paddle by at least one fastener, for example a bolt, a screw, or a rivet. Preferably, the projecting member comprises metal, plastic, or polymeric material, such as ultra high molecular weight polyethylene or a high density polyethylene. In one form, the paddle and the projecting member are integrally formed to provide a unitary construction.

  • Patent number: 5830061
    Abstract: An automotive combine has a frame adapted to move in a travel direction along the ground, a front housing pivotal on the frame, a cutter on the front housing for cutting standing crop, and a main thresher on the front housing having a front intake and a rear output for taking in the cut standing crop at the intake, threshing it, and ejecting it at the output as a chaff/grain stream and a separate chaff stream. A pair of separate conveyors on the frame each have an intake at the rear output for receiving the chaff/grain stream and a respective output for ejecting respective portions of the chaff/grain stream. One of the conveyor outputs is vertically spaced above the other conveyor output. An upper sieve at the one conveyor output and a separate lower sieve at the other conveyor output receive the respective portions of the chaff/grain stream and separate kernels from chaff therein.

    Abstract: An axial agricultural combine having a single element rotor defining a rotor axis. The rotor is housed in a rotor housing having an infeed section, a threshing section and a separating section. The infeed section of the rotor housing defines a infeed axis, the threshing section of the rotor housing defines a threshing axis and the separating section of the rotor housing defines a separating axis. The infeed axis is parallel to and in line with the rotor axis. The threshing axis is parallel to and offset from the rotor axis. The threshing axis is offset above and downstream from the rotor axis. The separating axis is parallel to and offset from the rotor axis. The separating axis is offset above and downstream from the rotor axis. The separating axis is more offset from the rotor axis than the threshing axis is offset from the rotor axis.

  • Patent number: 5497605
    Abstract: A grain combine according to the present invention includes a header having two sickles which extend on opposite sides of the combine for severing crop from a field, and two augers which extend on opposite sides of the combine for moving crop inward to central section of the combine. A centerline drive mechanical power transfer means directly connects to the two sickles and two augers at a point intermediate of the two sickles and two augers. A feeder has two conveyors, one located above the other, for transporting crop from the header to a primary threshing rotor. The two conveyors converge towards an aft end of the feeder to compress the crop therebetween. A perforated plate is provided beneath the aft end of the feeder for separating prethreshed grain from the crop. The prethreshed grain is passed through the perforated plate, onto a prethreshed grain conveyor and transported to a sieve section.

  • Patent number: 5462486
    Abstract: A reverser system for the feeder chain of a combine harvester comprises a hydraulic motor mounted on a slide and operated by a cylinder to move from a retracted position to a forward operating position. In the operating position the mechanical coupling connects the shaft of the hydraulic motor to a drive sprocket connected to the feeder chain. Hydraulic fluid to the cylinder and to the hydraulic motor is tapped from the lift cylinders of the combine from a solenoid operated diverter valve. A control unit controls the supply of the pressurized fluid to the cylinder while delaying the supply of fluid to the hydraulic motor so that the mechanical coupling is connected while stationary before the hydraulic motor starts. This arrangement can be provided by simple mechanical devices providing an inexpensive drive system.

    Abstract: A rotary combine including a feeder mechanism and a rotor assembly having an impeller assembly arranged at a forward end of a rotor. The feeder mechanism includes a housing which is pivotally connected to the combine about a transverse axis. The feeder mechanism housing envelops a conveyor assembly used to impart linear movements to the crop materials as they are advanced toward the rotor assembly. Prior to their introduction to the rotor assembly, the linearly advancing crop materials are discharged from a rotary member. A salient feature of the present invention involves the communicative relationship established between the rearmost rotary member from which the crop materials are discharged and the foremost end of the impeller assembly.
