Stray crop buildup expeller for rotary balers

摘要

The baler has a set of belts which bear against the surface of a cylindrical bale during formation thereof to compact the bale and to drive it rotatably about its longitudinal axis. Such belts are guided by shafts spanning the chamber of the baler, certain of which may be provided with annular expelling collars that rotate with the shaft and function to reject and expel stray crop material from the immediate vicinity of the shaft in order to prevent its accumulation and buildup. In the particular embodiment illustrated, the collars are attached to opposite ends of a shaft carried by the belt tensioning assembly whose shafts bear directly upon the top periphery of the bale during its formation and thus have a greater tendency than others to accumulate materials straying from the baling chamber. Preferably, the collars are used in connection with the shaft that rotates generally down and away from the area of normal accumulation such that the collars function to expel the stray material in the same downward and outward direction.
