Definitions

  • This disclosure relates to agricultural baler that simultaneously forms multiple bales of crop material and, more particularly, to a bale shape monitoring system that determines differences in bale length of the simultaneously formed bales.
  • bale binding mechanism is known from WO 2021/136989 (AGCO).
  • balers can process larger amounts of crop material but result in larger bales that are heavy and impossible to move by hand, making them unsuitable for use by a small hobby farmer.
  • bales that are uniform in size and that have uniform flakes.
  • the bales may have ununiform flakes and a bale on a first side of the dividing partition may be of a different size than that of a bale on a second side of the divider.
  • the invention is directed to an agricultural baler system having a pickup assembly configured to take cut crop material from the ground and move the crop material to a baling chamber and compress the crop material in the baling chamber with a reciprocating plunger into a growing bale.
  • the baling chamber is formed with a knife such that crop material moved into the baling chamber is split by movement of the plunger relative to the knife and pushed into left and right bale forming compartments to simultaneously form a first bale in the left bale-forming compartment and a second bale in the right bale-forming compartment.
  • the baler includes a bale shape monitoring system to monitor the shape of the bales being formed in the left bale forming compartment and the right bale forming compartment.
  • the bale shape monitoring system includes a bale length measuring device in each of the left and right bale forming compartments configured to measure changes in bale length, and determine differences in the bale length measured by the bale length measuring device in the left bale forming compartment with respect to the bale length measuring device in the right bale forming compartment indicating that crop material is not being fed into the pickup assembly evenly across a transverse width of the baler thereby causing a flake formed in the left bale forming compartment to be uneven with a flake formed in the right bale forming compartment.
  • FIG. 1 is a side elevation view of an example baler system configured to receive loose crop material and shape and secure the material into bales;
  • FIG. 2 illustrates a perspective view of the baling chamber of the baling system including a bale shape monitoring system
  • FIG. 3 illustrates a schematic of the bale shape monitoring system 302 of FIG. 2.

  • references to “one embodiment,” “an embodiment,” or “embodiments” in this description do not necessarily refer to the same embodiment and are not mutually exclusive unless so stated.
  • a feature, component, action, step, etc. described in one embodiment may also be included in other embodiments but is not necessarily included.
  • particular implementations of the present invention can include a variety of combinations and/or integrations of the embodiments described herein.
  • the baler system 102 includes a towing vehicle 110 and a baler 112.
  • the towing vehicle 110 may include a cab 114 wherein an operator may be located, an engine 116 operable to move the towing vehicle, and a power take-off (PTO) 118 operable to transfer mechanical power from the engine 116 to the baler 112.
  • PTO power take-off
  • the baler is hitched to the towing vehicle in any suitable manner, and power for operating the various mechanisms of the baler 112 may be supplied by the PTO 118 of the towing vehicle 110.
  • the example baler 112 is merely illustrative.
  • the baler has a baling chamber 120 within which bales of crop material 104 are formed.
  • the baler 112 is depicted as an “in-line” type of baler wherein the loose crop material 104 is picked up by a pickup assembly 122 and then loaded up into the baling chamber 120 by way of a stuffer chute assembly 124 including a charge forming stuffer chamber.
  • the baler 112 is an “extrusion” type baler in which the bale discharge orifice at the rear of the baler 112 is generally smaller than upstream portions of the baling chamber 120 such that the orifice restricts the freedom of movement of a previous charge and provides back pressure against which a reciprocating plunger 126 can act within the baling chamber 120 to compress charges of crop materials to form the next bale.
  • the dimensions of the discharge orifice and the squeeze pressure on the bales at the orifice are controlled by a compression mechanism as is understood by one skilled in the art.
  • the reciprocating plunger 126 presses newly introduced charges of crop material against a previously formed and tied bale to form a new bale. This action also causes both bales to intermittently advance toward a rear discharge orifice of the baler 112.
  • the completed bales 108 are tied with binding material, for example twine. Once tied, the bales may be discharged from the rear end of the baling chamber 120 onto a discharge platform in the form of a chute 128.

  • the electronic control unit may be in electronic communication with various actuators, sensors, and other devices within (or outside of) the baler.
  • the ECU 132 may communicate with various other components (including other controllers) in various known ways, including wirelessly.
  • Various alternative locations for the ECU 132 may be utilized, including locations on the towing vehicle 110.
  • the electronic control unit(s) may be a hardware, software, or hardware and software computing device, and may be configured to execute various computational and control functionality with respect to the baler (or towing vehicle).
  • the piston plunger 126 moves in a reciprocating manner within the baling chamber 120 from a front-dead-center position in which a plunger face of the piston plunger 126 is furthest from the forming bale 108 to a rear-dead-center position in which the plunger face is compressing the forming bale. More specifically, the piston plunger 126 repeatedly extends into the baling chamber 120 such that the plunger face contacts and compresses the charge of cut crop material 104 and the flakes that are already present therein and retracts to allow the next charge of cut crop material 104 to enter the baling chamber 120 from the stuffer chute assembly 124.
  • FIG. 2 shows the baling chamber 120 is formed with a chamber roof 202, left and right side walls 204 and a floor 206.
  • the plunger 126 pushes the crop material 104 against and past a stationary splitting knife 208 which extends vertically in the baling chamber 120 between the floor 206 and the roof in a plane parallel with the side walls 204.
  • the compressed crop material split by movement of the plunger 126 relative to the knife 208 is pushed into two separate baleforming compartments, a left bale-forming compartment and right bale-forming compartment, effectively splitting the baling chamber 120 into two smaller baling chambers.

Abstract

L'invention concerne un système de presse à balles agricole (102) ayant un ensemble de ramassage (122) conçu pour ramasser un matériau de récolte coupé sur le sol et déplacer le matériau de récolte jusqu'à une chambre de mise en balles (120). La chambre de mise en balles comporte un couteau (208) de telle sorte que le matériau de récolte soit divisé dans les compartiments de formation de balles gauche et droit (304, 306) pour former simultanément une première balle dans le compartiment de formation de balles gauche et une seconde balle dans le compartiment de formation de balles droit. La presse à balles comprend un système de surveillance de forme de balle (302) pour surveiller la forme des balles formées. Le système de surveillance de forme de balle comprend un dispositif de mesure de longueur de balle (214) dans les compartiments de formation de balle gauche et droit conçus pour mesurer des changements de longueur de balle et déterminer des différences de longueur de balle mesurées par le dispositif de mesure de longueur de balle dans le compartiment de formation de balle gauche par rapport au dispositif de mesure de longueur de balle dans le compartiment de formation de balle droit.
