  • Patent number: 5479876
    Abstract: An arrangement for the automatic application of milking apparatus to a milk animal including a milking apparatus store, a milking apparatus handling device including a milking apparatus carrier movable on the device and a teat sensor on the handling device together with at least one animal position sensor and a control unit responsive to the animal and teat sensor to operate the handling device, the arrangement being such that when an animal is sensed to be in milking position the control unit operates the handling device to take milking apparatus for a teat of the animal from the store in the carrier to a specific teat with the carrier moved to a sideways offset at a selected angle to the device and the teat sensor in range of the teat.

  • Patent number: 5069160
    Abstract: An arrangement to apply a milking apparatus to the udder of an animal at a milking point including a store for the apparatus, a handling device having an elongate arm to support and move the apparatus between an apparatus acquisition point and the milking point, a stall to define a specific space for an animal to be milked fixedly related to the acquisition point and the milking point, including guides to retain loosely in the space an animal to be milked, sensors to sense retained animal position with respect to the fixedly related space and points and provide a first signal indicative of sensed animal position, pneumatic elements in the device to swing and to longitudinally displace the elongate arm to move and position the elongate arm and any supported apparatus, and control circuitry to control the pneumatic elements to operate the arm to acquire milking apparatus at a position forward of the teats of a retained animal, the control circuitry being responsive to the first signal to move the acquired appar

  • Patent number: 4998945
    Abstract: Transplanting equipment comprises a line of individual plant pick-up devices, first support means for transversely moving a first row of containers into vertical alignment with the pick-up devices, control means for bringing the pick-up devices into a plant-supporting or plant-releasing mode as appropriate, horizontal drive means operative to bring the pick-up devices into vertical alignment with the containers of a second row having a different center-to-center spacing to the containers of the first row, second support means for transversely moving the second row of containers out of vertical alignment with the pick-up devices, and vertical drive means for moving the pick-up devices towards or away from the first and second support means to allow the support or release of plants by the pick-up devices as determined by the control means.

  • Patent number: 4572538
    Abstract: A coupling device for hitching a trailer to a vehicle such as an agricultural tractor comprises a frame for attachment to the underside of the vehicle, and a guideway carried by the frame which can be moved (e.g. pivotally) downwardly when the frame is attached under the vehicle. The guideway is adapted to receive and guide a trailer-mounted tow-bar assembly from a rearward to a forward location. When in the forward location, which is preferably in front of the vehicle's rear axle, latching means can be actuated to lock the tow-bar assembly in its forward location. The latching means can be actuated by upward movement of the guideway. The coupling device includes provision for pitch, roll and yaw movements between vehicle and trailer.
