Definitions

  • the invention relates generally to agricultural implements. More specifically, but not exclusively, the invention relates to an automatic grain flow gate control for grain carts.
  • Agricultural wagons such as grain carts, aid in the harvesting of agricultural products such as corn, beans, or other crop (collectively "particulate material").
  • the grain carts are configured to receive the harvested grain from a combine or other implement so that the combine can continue to harvest the grain. Many times, a grain cart will move alongside a combine as the combine harvests grain so that the combine can deliver harvested grain to the cart such that the combine will be able to continue to harvest without having to stop to empty its hopper or hoppers. Once the combine has transferred harvested grain to the grain cart, the grain cart is able to transport the grain to a storage or transport vessel, such as a semi-trailer.
  • a storage or transport vessel such as a semi-trailer.
  • Grain carts may include a flow gate, which is used to selectively block one or more augers within the cart.
  • Augers are generally used to transport the grain from the grain cart to another vessel.
  • a vertical or lift auger is positioned on or in the grain cart with one end in or near the grain, and the other end extending generally upwardly and outwardly from the cart. The positioning of the lift auger allows the grain to be moved from the storage area of the grain cart to the trailer.
  • the lift auger may also be adjustable or movable such that the auger can be directed to aim the grain towards trailers of differing heights, sizes, or the like. The adjustability also allows the grain to be directed to exact locations within the trailer or area.
  • Grain carts may also include a floor auger that is positioned generally at the bottom of the storage area of the grain cart.
  • the floor auger extends from the rear of the storage area to near the front, or at least to an area adjacent the lift auger.
  • the floor auger aids in directing grain in the cart to the lift auger to increase the speed of transport for the grain from the grain cart to the storage vessel, i.e. semi -trailer.
  • the flow of grain from the grain cart to the storage or transport vessel may need to be regulated, for instance, so that the storage vessel does not fill up too fast or to prevent spillage of the grain.
  • Flow gates have been added to selectively cover the floor auger in the grain carts. The flow gates regulate the amount of grain that is able to flow into the floor auger and corresponding lift auger.
  • Grain cart systems today rely completely on the operator to close the grain flow gate and to open the flow gate to the correct setting for the crop conditions. Dual auger grain carts, due to their high flow capacity, risk failing to start the augers if the flow gates are left open while the grain bin is filled. Manually dumping grain out of the system is required to relieve the torque on the system.
  • An agricultural wagon comprising a storage bin supported by wheels and adapted to connect to a vehicle, the bin including front, rear, and side walls.
  • a lift auger operatively connected to the interior of the storage bin and configured to move the particulate material at least partially upward and out of the storage bin.
  • At least one flow gate movable between a closed positioned to substantially block access to the lift auger and an open position to allow grain to be in communication with the lift auger.
  • An actuating mechanism operatively connected to the flow gates.
  • a linkage operatively connected to the actuating mechanism.
  • a visual indicator operatively connected to the linkage.
  • a rotation sensor associated with the lift auger and a control system operatively to each sensor.
  • the flow gate will remain closed until a minimum auger speed is met, at which point the flow gate will begin to open. As the operator throttles the PTO speed down past the minimum auger speed, the gates will automatically close. Additionally, this device will govern PTO load by adjusting the flow gates closed when there is too much PTO load or open when the PTO load is light.

Abstract

L'invention concerne un outil agricole tel qu'un chariot à céréales permettant le déplacement d'un matériau particulaire de l'intérieur du chariot à un récipient de stockage distinct comprenant un bac défini par des parois. La remorque agricole est destinée à recevoir, à stocker et à transporter un matériau particulaire, tel que des céréales. Un système de commande électromécanique détecte la vitesse de prise de force (PTO) et/ou le couple et la position de l'obturateur d'écoulement. La rétroaction provenant de chaque capteur permet une commande automatique de la position de l'obturateur d'écoulement par l'intermédiaire d'une vanne électrohydraulique. Le système de commande peut être conçu pour permettre à l'opérateur d'effectuer des réglages en fonction de sa façon de travailler et des paramètres de son tracteur. La position d'ouverture maximale de l'obturateur et la vitesse minimale de la tarière sont deux réglages de base qui peuvent être utilisés. De plus, un réglage de sensibilité à la décélération réglerait la réponse de la fermeture d'obturateur lorsque la charge de PTO est élevée. Ceci pourrait être réglé par l'opérateur ou automatiquement.
