Abstract:
A rectangular baler having a wall positioning system, the baler comprising a bale chamber which comprises a plurality of walls including a movable wall section. The wall positioning system comprises positioning means for moving the movable wall section from a first position to a second position. The positioning means are configured for applying pressure to a first pressure point and to a second pressure point on the movable wall section such that the second position of the movable wall section is substantially parallel to the first position of the movable wall section (111). The first pressure point and the second pressure point are spaced apart along a longitudinal direction of the bale chamber.
Abstract:
A system for determining an amount of and applying a preservative to an individual charge (50f) of crop material, wherein the charge is combined with other charges (50a-e) to form a bale (14). Loose crop material (12) is collected and packed into a feeder chute (58) in such a manner as to pre-compress the material to form the charge (50f). A moisture content of the charge is measured by a sensor (36) while the charge is still in the feeder chute. The charge is moved into a forming chamber (32), and a control unit (40) determines a correct amount of a preservative to apply to the charge based on the moisture content. The correct amount of the preservative is applied to the charge either before or after the charge (50f) is incorporated into the bale (14). Thus, the system measures the moisture content of each charge, and measures the moisture content of the same charge to which the preservative is applied.
Abstract:
A baler apparatus includes a baling chamber (2) with at least one adjustable wall (4) for adjusting the compression of a body of bale material (18). A reciprocating plunger (10) is operable to compress the bale material (18) and a binding device (17) binds the compressed material to form a bale by the use of twine loops (22). An adjustment means in the form of a guide or rollers (41) is provided for the purpose of varying the length of the twine loops 22a, 22b) when binding the bale in order to reduce compression within part of the body of bale material and avoid twine breakage which can otherwise occur as a bale is ejected from the baler.
Abstract:
A method of operating an agricultural baler (10), including the steps of: measuring at least one physical input parameter (50) associated with a compression profile of crop material in a bale chamber (26) of the baler (10); analyzing the compression profile of the crop material (52), dependent upon the measured at least one physical input parameter; and adjusting at least one physical output parameter of the baler (54) which affects the compression profile of the crop material in the bale chamber (26).
Abstract:
An agricultural baler system (10) including a gathering device (12), a bale chamber (26), a compressing device (30) and at least one sensor (40). The gathering device (12) is configured to gather crop material. The bale chamber (26) is coupled to the gathering device (12), with at least some of the crop material being directed into the bale chamber (26). The compressing device (30) is coupled to the bale chamber (26). The compressing device (30) periodically compresses the crop material in the bale chamber (26). The sensor (40) is coupled to the bale chamber (26) and it produces a signal. The signal contains information that includes the load on the compressing device (30) and/or the density of the forming bale.
Abstract:
A sensor detects a characteristic of accumulated crop material and a controller manipulates the speed of a baling chamber in response thereto. The speed of a baling chamber of a variable speed baler is manipulated in response to a characteristic of an accumulated crop material. For example, the height of accumulated crop material in an accumulation area may be detected and the speed of the baling chamber manipulated in response thereto. The rate of growth of the bale may also be determined and used in manipulating the speed of the baling chamber.
Abstract:
A baler apparatus includes a baling chamber (2) comprising a channel having an inlet end (6) and an outlet end (8), a reciprocating plunger (10) adjacent the inlet end of the baling chamber that is operable to compress a body (18) of bale material within the baling chamber, and a binding device (17) for binding the compressed body of bale material to form a bale (20). The baling chamber (2) has at least one adjustable wall (4) for adjusting the compression of the bale material during formation of a bale.
Abstract:
A square baler is described comprising a control system having a closed loop mode of operation in which at least one of the volume of the feeder duct 16 and the threshold pressure of the pressure sensor 32 is varied automatically to maintain the capacity parameter within one of a plurality of desired capacity ranges. The desired capacity range is selected by the control system in such a manner as to maintain the width of each slice in the finished bale within predetermined limits.
Abstract:
Eine Kombination setzt sich aus einem Zugfahrzeug (10) und einem mittels einer Deichsel (14) vom Zugfahrzeug (10) gezogenen, durch Räder (34) auf dem Erdboden abgestützten Gerät (12) zusammen, welches ein mit einem Feld zusammenwirkendes Bearbeitungselement (36) umfasst. Eine Steuerungseinrichtung (52) ist mit einem ersten Aktor (54), der zur Verstellung des Winkels zwischen der Deichsel (14) und dem Gerät (12) angeordnet ist, und mit einem zweiten Aktor (58) verbunden, der zur Verstellung des Winkels der Räder (34) des Geräts (12) um die Hochachse angeordnet ist. Die Steuereinrichtung (52) ist betreibbar, die beiden Aktoren (54, 58) in einer Weise anzusteuern, dass die Längsachse des Bearbeitungselements (36) stets zumindest näherungsweise orthogonal zu einer Solllinie (66) orientiert ist.
Abstract:
According to the invention there are provided means and a method for controlling a square baler, wherein: - the length of the bale (20) in progress is determined by a bale length sensor; - the crop remaining to be baled before completion of a job is predicted by the operator; and - depending on the prediction and the length of the bale (20) in progress, a control system ensures that all bales completed after the receipt of the prediction signal exceed a predetermined minimum length at the completion of the job.
