Plunger and Pre-Compression Chamber Link

摘要

An agricultural baler. The baler includes a baling chamber with a plunger that is provided to reciprocally move in the baling chamber. The baler further includes a pre-compression chamber with a slice pushing mechanism provided for periodically pushing a slice of crop material into the baling chamber. The plunger and the slice pushing mechanism are mechanically linked via respective driving systems to ensure synchronization, wherein a coupling means or coupling element is mounted in the mechanical link. The coupling means or coupling element is provided to adjust a synchronization timing.

1. An agricultural baler comprising:
a baling chamber comprising a plunger configured for reciprocally moving in the baling chamber; a plunger driving mechanism configured for driving the plunger; a pre-compression chamber comprising a slice pushing mechanism configured for periodically pushing a slice of crop material into the baling chamber; a slice pushing driving mechanism configured for driving the slice pushing mechanism, the plunger driving mechanism and the slice pushing driving mechanism being linked by a mechanical link to ensure synchronization; a first rotating shaft connected to the plunger driving mechanism; a second rotating shaft connected to the slice pushing driving mechanism; and a coupling element comprising an intermediary element linking the first and second rotating shafts, the coupling element mounted in the mechanical link and being provided to adjust a synchronization timing, the intermediary element movable between a first position and a second position, the first and second rotating shafts having a relative angular position with respect to each other, wherein the relative angular position of the first and second shafts when the intermediary element is in the first position is different from the relative angular position of the first and second rotating shafts when the intermediary element is in the second position.
