Bulk media spreader transversal actuator assembly with kinematic hyperextension prevention

A bulk media spreader transversal actuator assembly, comprising:

• a drive converter;
• a motor connected to the drive converter;
• a linear motion shaft slidably positioned in a shaft housing, the shaft housing connected to the drive converter and the linear motion shaft connected to the drive converter such that rotational operation of the motor is converted to a linear motion of the linear motion shaft by the drive converter;
• a hyperextension prevention device rotatably connected to the linear motion shaft and rotatably connected to a rotatable lever of a bulk media spreader, rotatable displacement of the lever by extension or retraction of the linear motion shaft acting to change an operating position of a hopper gate through which media in the bulk media spreader is dispensed;
• and
• a detent position of the hyperextension prevention device provided by engagement of a rotation engagement ball in a V-shaped notch resisting rotation of the hyperextension prevention device until a biasing force of a biasing member engaged with the rotation engagement ball is exceeded by a rotational force acting on the hyperextension prevention device through the lever;
• wherein the hyperextension prevention device includes
• a housing which axially and rotatably receives a rotational motion sleeve, the rotational motion sleeve being cylindrical in shape and rotatable with respect to a rotational axis;
• a lever connection ring rotatably connected to the housing and including a longitudinal slot which receives and matingly engages the lever;
• and
• a first cover plate positioned in contact with a first outer face of the housing retaining the rotational motion sleeve with respect to the housing;
• wherein the lever connection ring is cylindrically shaped and positioned on the side of the housing opposite to the first cover plate, is mounted in proximity to a second outer face of the housing which is positioned opposite to the first outer face of the housing;
• and
• the lever is retained within the longitudinal slot using a second cover plate which is positioned over the longitudinal slot on the lever connection ring.
