  • Patent number: 6349775
    Abstract: A method and apparatus for obtaining optimal cultivation of a parcel of land. A soil working machine with drivable working members, such as a rotary harrow, is provided with soil working members which rotate about approximately vertically orientated axes, and cooperates with a geographic positioning system such as DGPS, GPS, Lorean or a dead reckoning system to determine on a continual basis the actual position of the soil working machine on a parcel of land. Simultaneously, the condition or the composition or both of the underlying soil is determined and data of same is transmitted to a processing unit which maps the parcel of land into subareas wherein the states of the soil are the same. A control unit applies this mapping for controlling the soil working members during the soil working machine's operations so that each subarea of the same soil state is optimally cultivated.

  • Patent number: 5195455
    Abstract: A device for maintaining dairy animals and surface areas where they may be confined in a clean condition, and providing a station for feeding, milking and elimination of wastes which is movable as a unit. The station has a waste disposal at the rear and a feeder forward. An electronic system causes an animal to enter the station prior to waste elimination. A sensor determines the presence of animal waste. An electronic system that remotely guides the animal, comprises a radio transmitter at the station, a radio receiver mounted on the animal to guide the animal by shock or sounds to the station and/or sounds produced at the station attract the animal. A sensor on the animal's tail that signals the onset of elimination or presence of waste, may be coupled to the station's electronic system, or to a speaker near the animal's ear for producing unpleasant sounds to discourage elimination outside the station. Electronic systems are used to reward the animal after its elimination in the station.

  • Patent number: 5046664
    Abstract: A spreader for granular and/or powdery material such as fertilizer comprises a hopper having two delivery parts. Distribution members are provided under the delivery parts for broadcasting material fed to them from the hopper. The distribution members are mounted on a carrier rigidly supported by the hopper. This construction results in a fixed position of the distribution member with respect to the delivery parts, regardless of deflections which may occur as a result of the weight of material in the hopper. The distribution members may be driven by a mechanical transmission from a power take-off shaft of a tractor, or by a hydraulic motor. The mechanical transmission includes a horizontal shaft connected to two vertical shafts for rotating the distribution members via bevel gears and is contained in a hollow tube with gear boxes on either end which maintain the axes and levels of the vertical shafts and distribution members in fixed relative positions.

  • Patent number: 4884640
    Abstract: A soil cultivating implement comprising a row of power-drivable, soil working members supported by a hollow frame extending substantially horizontally perpendicular to the implement's intended direct of operative travel to provide selectively upwardly or downwardly directed forces upon that row via the hollow frame. A supporting ground roller is connected behind the row, its rotary axis being contained in an imaginary vertical plane. A mobile implement provides mass to exert a downward force on the cultivating implement at a coupling point which, in turn, is translated into an upward force on the frame's forward aspect by way of arms and strong pivots, such arms being turnable about the ground roller's rotary axis. The upwardly directed force assists soil-working members automatically to elevate as needed for riding over rocks or other buried obstacles without significant damage.

  • Patent number: 4838207
    Abstract: An implement for milking an animal, such as a cow, that comprises a milking parlor where the animal can be positioned so that a robot arm which carries teat cups for application to the animal's teats can be positioned between the animal's front and rear legs. The robot arm is linked to a padded sensor that contacts the animal's hindquarters such that the robot arm maintains a relatively stable position between the animal's legs upon the animal's forward or rearward movement. The end of the robot arm can be located precisely relatively to the teats by an ultrasonic sensor. The implement provides for individual application of each teat cup to a teat and, once the teat cup is attached to the teat, the teat cup to be released from the robot arm so that a flexible connecting member provides the link between the rotor arm and the teat cup during milking. Upon completion of the milking, the flexible connecting member is used to pull the teat cup to the robot arm and seat it thereon.

  • Patent number: 4805557
    Abstract: A mechanism that automatically attaches teat cups to a cow's teats including four telescopically extensible members which each carry a teat cup via a teat cup support which resiliently supports its corresponding teat cup in an upright position. Each extensible member has its own stepper motor to raise and lower the corresponding teat cup and a further stepper motor to move the extensible member horizontally within limits. An ultra-sonic radiation member is carried on a platform between the teat cups as seen in plan which emits a horizontal ultra-sonic beam that is reflected and focused upwardly and caused by movement of the reflector systematically to scan the cow's udder and to locate the teats by their comparatively shorter distances from the reflector. The disposition of the teats is thus sensed by a sensor unit which controls a stepper motors and causes the extensible members independently to raise the teat cups to be received by and attached to corresponding teats for the milking operation.
