Abstract:
The present invention is related to an agricultural baler for producing rectangular bales, provided with a baling chamber (1) formed by four side walls (4-7). A reciprocating plunger (8) is moving back and forth in the enclosure formed by said walls, thereby compressing crop material and forming rectangular bales. Actuators are provided for adapting the cross-section of the enclosure depending on the required pressure that needs to be exerted on the advancing bale. The actuators apply their force on the sidewalls along transversal support beams (15) or brackets forming the 'density belt'. The baling chamber is provided with one or more friction or moisture sensors (16). According to the invention these sensors are placed at the location or in the immediate vicinity of one or more reinforcement means (15, 20, 25) arranged in connection with at least one of said sidewalls, said reinforcement means forming an obstruction that locally neutralizes or limits deformation of said sidewalls by bulging outwards with respect to the interior of the baling chamber, said deformation being a consequence of the bale forming process.
Abstract:
An agricultural square baler (1) comprising a baling chamber (2), for compressing crop by a plunger (3), and a plunger drive (6) connected to the plunger (3) provided to drive the plunger (3). At least one connecting rod (7) longitudinally delimited by a first (8) and a second end (9) is provided to transfer the rotational movement of the plunger drive (6) into the linear reciprocal movement of the plunger (3). Each of the ends (8,9) of the connecting rod (7) having a first surface (13, 31). An attachment (15, 17,40) connects a constraining element (12,30) with the connecting rod (7) at an attachment location (16) away from the first (13,31) surface of the connecting rod (7).
Abstract:
In the invention, at least part of the side (42) of the crossbeann (40) facing the knotter (30) is inclined at an angle of more than ninety degrees to the upper wall (44) of the baling chamber (20) in order to permit a smooth flow of air from the fan past the knotter (30).
Abstract:
An agricultural baler (70) comprises a shaft (3), a flywheel (2) connected to the shaft (3), a plunger (13) connected to the flywheel (2) via a crank (6), a brake system (40) adapted for providing a brake force (F2) for decelerating the flywheel (2), at least one sensor (43) for providing sensor data indicative for at least one moving part of the baler, and a brake control system (47) comprising a processing system, e.g. a processor provided with an algorithm for stopping the crank (6) in a predefined launch position range, based on a mathematical model of the baler.
Abstract:
An agricultural baler (70) comprises a shaft (3), and a flywheel (2) connected to the shaft (3), and a brake system (40) for holding or for stopping the flywheel (2). The brake system (40) may be of the drum-type and/or of the caliper-type. The caliper-type comprises a brake disc (41) and a brake caliper (51). The brake disc (41) may be mounted on the flywheel (2), or on the shaft (3). The brake system (40) may have an adjustable braking force. The disc brake (40) may be manually or hydraulically activated. The brake system (40) may be remotely activated from a tractor (17).
