Abstract
A device for braking lines of tying twine, for agricultural machines, of the type of balers, round balers and the like. Such machines are provided with assemblies for typing bales of previously-cut agricultural products, or the type of grass, wheat, maize, hay, forage, and the like. The braking device includes an electronic unit for controlling and managing at least one actuator for moving at least one braking element, which is actuated by the electronic unit by way of the actuator, in order to retain at least partially at least one respective length of at least one line of twine, during its unreeling.
Claims10
A device for braking lines of tying twine for round balers, for agricultural machines, which are provided with assemblies for tying bales of previously-cut agricultural products, comprising an electronic unit for controlling and managing an actuator (2) for moving a braking element (3), which is actuated by said electronic unit by way of said actuator (2), for retaining a length of at least one line of twine (A), during unreeling of the twine (A), wherein said braking element (3) comprises a skid (4) functionally associated with said actuator (2) and oscillates about a working axis (D), said skid (4) being pressed against a reference surface (5) for the braking of a respective length of the at least one line of twine (A), which is guided and clamped between said surface (5) and said skid (4) during its unreeling.
A device for braking lines of tying twine for round balers, for agricultural machines, which are provided with assemblies for tying bales of previously-cut agricultural products, comprising an electronic unit for controlling and managing an actuator (2) for moving a braking element (3), which is actuated by said electronic unit by way of said actuator (2), for retaining a length of at least one line of twine (A), during unreeling of the twine (A), and an oscillating skid (4), wherein said actuator (2) is of a linear type, and comprises a rod (6) that can translate along a straight path (E), in order to command the oscillation of said oscillating skid (4).
A device for braking lines of tying twine for round balers, for agricultural machines, which are provided with assemblies for tying bales of previously-cut agricultural products, comprising an electronic unit for controlling and managing an actuator (2) for moving a braking element (3), which is actuated by said electronic unit by way of said actuator (2), for retaining a length of at least one line of twine (A), during unreeling of the twine (A), and a skid (4) including a plate (9), which is designed, together with a surface (5), to clamp the twine (A), for its braking, said plate (9) being rigidly supported by a rib (10) articulated to a rod (6) of said actuator (2), in order to command oscillation of said skid (4) around a working axis (D) as a consequence of translation of said rod (6) along a straight path (E).
