Abstract

An electrical, end control, power drive mover unit for agricultural sprinkler irrigation systems comprises oppositely mounted, dual electric motors adapted to revolve about a stationary bull gear by reason of drive pinions respectively driven by the motors. The motors are structurally supported and rigidly secured to a rotatable sprinkler pipe section by means of respective, mutually substantially symmetrically oriented platforms, advantageously respective lengths of structural channel, that serve to also support respective speed reducing gear boxes, desirably in-line with the associated motors. Structural means, advantageously in the form of an annular plate rigidly secured to the sprinkler pipe section, serves, in turn, to rigidly fasten the platforms to the sprinkler pipe section at diametrically opposite positions thereon. The sprinkler pipe section is rotatably carried by a tubular bearing, which is rigidly attached to the chassis frame of the mover unit for the system and to which the bull gear is rigidly secured. Sprockets affixed to the sprinkler pipe section serve to drive traction wheels of the mover unit in synchronism with rotation of the sprinkler pipe.

Dependent claims

An electrical, end control, power drive mover unit for agricultural sprinkler irrigation systems, comprising a wheeled frame having a pipe section of an irrigation sprinkler pipeline rotatably mounted thereon substantially parallel with the axes of rotation of the wheels thereof;

a bull gear rigidly affixed to said frame and encircling said pipe section;
dual, mutually substantially symmetrically oriented, structurally separate platforms rigidly attached in mutually parallel relationship to and supported by said pipe section in diametric opposition to each other and adjacent to said bull gear;
structural means rigidly affixing said platforms in common to said pipe section, said structural means comprising an annular disc plate encircling the pipe section at a side of said platforms and rigidly affixed thereto;
electric motor and speed reducing gear box sets mounted on the respective platforms in mutually substantially symmetrical orientation, the gear box of each set having an output shaft with a pinion drive gear thereon in mesh with said bull gear;
an electrical connection for an elongate electrical power cable which is adapted to extend along the irrigation pipeline to an end thereof for connection with a source of electric power;
and drive means connecting said pipe section with wheels of said wheeled frame for moving the mover unit when the electric motors are energized.
