Square baler having planetary plunger drive

摘要

A powered square baler is operable to form a bale by compressing loose material. The powered square baler broadly includes a chassis, a plunger assembly, and a plunger drive. The chassis includes a baler frame that presents a baling chamber to receive the loose material. The plunger assembly includes a reciprocating plunger head and a pair of connecting arms attached to the plunger head. The reciprocating plunger head is slidably mounted relative to the frame and is operable to reciprocate into and out of the chamber and apply a compressive force to the loose material. The plunger drive includes a pair of planetary gear trains and a common drive shaft that powers both of the gear trains, with each gear train drivingly connected to a corresponding one of the connecting arms to cooperatively power the plunger assembly.

1. A powered square baler operable to form a bale by compressing loose material, the powered square baler comprising:
a chassis having a baler frame forming a baling chamber to receive the loose material; a plunger assembly having a reciprocating plunger head and a pair of crank arms attached to the plunger head, the reciprocating plunger head being slidably mounted relative to the frame and operable to reciprocate into and out of the chamber and apply a compressive force to the loose material; and a plunger drive, wherein the plunger drive includes a pair of planetary gear trains and a common drive shaft that powers both of the planetary gear trains, with each of the planetary gear trains drivingly connected to a corresponding one of the crank arms to cooperatively power the plunger assembly, wherein each of the planetary gear trains comprises a ring gear, a carrier, a plurality of planet gears, a corresponding plurality of shafts, and a sun gear.
