Bulk media spreader transversal actuator assembly with kinematic hyperextension prevention

摘要

A bulk media spreader transversal actuator assembly includes a drive converter. A motor is connected to the drive converter. A linear motion shaft is slideably positioned in a shaft housing. The shaft housing is connected to the drive converter and the linear motion shaft is 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 is connected to the linear motion shaft and to a rotatable lever of a bulk media spreader. Rotatable displacement of the lever by extension or retraction of the linear motion shaft acts to change an operating position of a hopper gate through which media in the bulk media spreader is dispensed.

1. 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; and a hyperextension prevention device connected to the linear motion shaft and 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; 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 first cover plate positioned in contact with a first outer face of the housing retaining the rotational motion sleeve with respect to housing; a cylindrically shaped lever connection ring positioned in contact with a second outer face of the housing, the second outer face located opposite to the first cover plate; and the cylindrically shaped lever connection ring including a longitudinal slot which receives and matingly engages the lever, the lever retained within the longitudinal slot using a second cover plate which is positioned over the longitudinal slot on the lever connection ring.
