  • Patent number: 7398636
    Abstract: A wheel mounted grain harvester includes a harvesting head for depositing grain in a grain handling assembly comprised of a plurality of grain moving parts. Control means are located on the harvester for selectively interrupting grain flow along the grain moving parts causing harvested grain from a new separate row segment to temporarily accumulate. Means are provided for transporting the harvested grain from separate row segments into separate collection bins permit the separate evaluation of the harvested grain in each row segment. Means are provided for moving the harvester along the row at a constant rate of speed to avoid the necessity of stopping the harvester between row segments to effect the separate evaluation of the harvested grain. The selective interruption by the control means is accomplished by either interrupting at least one of the grain moving parts or by selectively closing a movable blocking wall mounted on the harvester.

  • Patent number: 7337733
    Abstract: A distance measuring device mounted to a planter used to plant crops. The distance measuring device has a cable extending between a first pulley and second pulley wherein the cable has at least one target. A sensor located adjacent the first pulley and connected to a controller sends a signal to the controller when the sensor detects the target. Adjacent the second pulley is an encoder that sends a second signal to the controller based upon the rotation of the second pulley such that the controller can determine the amount of distance that the planter has traveled.

  • Patent number: 7111567
    Abstract: A seed meter for planting seeds includes a seed plate rotatably mounted within a housing. A rotary seed chamber (RSC) is mounted in the housing adjacent the seed plate and movable between first and second positions, to permit the seed plate to singularly select individual seeds from the RSC while in a first position, and to dump seed therefrom as well as blocking seeds from entering the seed plate while in a second position. A seed intake compartment having an inlet end, and a discharge end is located adjacent the RSC. A valve is located in the intake compartment to intermittently prevent seed from flowing from the inlet end to the discharge end. A power means actuates both the RSC and the valve. A wing plate on the rotary seed chamber opens and closes the discharge end as the rotary seed chamber is in its first and second positions, respectively.

  • Patent number: 6749810
    Abstract: The method for presenting grain for NIR spectography examination includes causing the grain to move downward across a sloping presentation surface; associating the optics of an NIR spectography apparatus with the presentation surface to permit light from the optics to be projected into the curtain of grain at a substantial right angle with respect to the direction of flow of the curtain of grain over the presentation surface. An apparatus for presenting grain for NIR spectography examination includes the structure for practicing the aforementioned method.

  • Patent number: 6505124
    Abstract: A GPS system to provide planter tripping for crop research plots provides the longitude and latitude of the first trip location and provide a continuous flow of location information. A control computer calculates the next tripping location and provides a signal to the planter at that location and each subsequent tripping location in the field grid. A GPS receiver mounted on the planter provides location information. When the first plot is manually tripped the computer will use vector information to determine the next tripping location. The computer has a program that allows entry of planted length and alley width so the system can calculate the next plot location from the original planter trip. Additional parameters entered in the program include the number of trips needed to pass across the field and the number of passes that would be needed to complete the planting grid.

  • Patent number: 6474500
    Abstract: A method of planting field seeds in rows with different varieties of seeds involves determining the variety of the seeds to be planted; placing the seeds for rows of predetermined length in different groups in elongated cell pack strips for each variety, with each cell pack strip including individual cells with individual seeds. A plurality of subgroups of cell pack strips are selected sequentially from the groups of cell pack strips in chronological order that they are to be planted in a single row in a field. The subgroups are then placed in magazines to maintain the order of the subgroups for the subsequent planting. The locations in a field are determined where the varieties are to be planted. The magazines are mounted on a field row planter with the magazines being associated with rows in the field to which the respective magazines correspond. The planter is moved longitudinally through the field.

  • Patent number: 6330767
    Abstract: An apparatus for efficiently removing grain from a grain storage device, which uses a plurality of augers. An unloading auger is used to begin removal of grain from a grain storage device. As the amount of grain decreases, a proximity sensor sends an activation signal to a cross auger that rests horizontally on the bottom of the grain storage device. The cross auger will pull the remaining grain to the entry point of an unloading auger. The unloading auger then removes the grain from the grain storage device.

  • Patent number: 6319118
    Abstract: A seed package handling system for a test plot combine. A seed packaging assembly in the combine packages the seeds and deposits the packages onto a conveyor, which transports the packages to a first hopper. After the first hopper has received a predetermined quantity or weight of seed, the first hopper is raised on an elevator and then tilted so as to dump the seed packages into a larger second hopper. After the second hopper has received a predetermined quantity or weight of seed, the second hopper is tilted to discharge the seed packages into a wagon separate from the combine, which transports the seed packages to a processing facility. The movement of the conveyor and first hopper is controlled by a PLC.

  • Patent number: 6230476
    Abstract: A combine gathering belt assembly has a pair of continuous sprocket chains each supported on rotatable sprockets at their opposite ends, and having spaced parallel inner traveling chain portions. A plurality of flexible spaced belt segments are secured to the sprocket chains. The belt segments on one chain are staggered with respect to the belt segments on the other chain. Each belt segment has a base end adjacent the chain to which it is attached, and an outer end extending forwardly while between the spaced parallel inner traveling chain portions. The belt segments are of such size and spacing that an outer end of a belt segment on one chain closes on a base end of a belt segment on the opposite chain while in the spaced parallel inner traveling chain portions. The closed belt segments then open up as they move around the rotatable sprockets on one discharge end of chains to release plant segments that may be bound by opposite belt segments while moving through the spaced parallel inner chain portions.

  • Patent number: 5664402
    Abstract: The seed packaging machine of this invention is mounted on a conventional plot combine. The harvested seed is blown to a receiving compartment where the seed is weighed and tested for moisture. A bag roll comprising a plurality of bag portions is fed through power rolls to a seed deposit station. A blower blows open the endmost bag and the seed is deposited in the bag portion. A sealing pressure bar is pivoted toward a thermal bar with the top of the bag portion therebetween to seal the bag. The bag is then released to drop into a storage bin. Bar codes are imposed on the bags and are scanned as they approach the deposit station. A computer is connected to all operating components to coordinate the sequential operation thereof. The range and row numbers of the harvested field are imposed on the computer memory, and the computer associates each bag containing harvested seed with the range and row from which the seed was harvested. The bags are perforated to facilitate subsequent drying of the seed.
