1. Field of Invention
This invention relates to a baling apparatus, and more particularly to a square baler with plunger providing increased impact force.
2. Description of Related Art
Conventional square hay balers include a bale forming chamber and a reciprocating plunger that slides into and out of the chamber. As the chamber receives loose hay material, the plunger slides into the chamber during a compaction stroke to compress the loose hay material into the form of a bale. Such balers typically include a drive train that transmits power to the reciprocating plunger.
However, prior art square hay balers have certain deficiencies. For instance, conventional hay balers apply very high forces to the plunger in order to complete the compaction stroke. Because these forces are transmitted by the drive train and by connecting rods that connect the drive train to the plunger, the connecting rods and drive train components must be designed to accommodate this loading.
