AI Technical Summary

Technical Problem

Agricultural balers face damage to stuffer assembly components due to obstacles like stones, leading to increased load on tines and potential breakage, resulting in downtime and poor bale quality, as existing solutions either allow tines to pivot out of operation or rely on shear bolts that may not fully protect the system.

Method used

A stuffer assembly with tines slidably connected to a tine bar, allowing individual tines to retract when overloaded, maintaining operational engagement with crop material and reducing load on the tine bar and drive mechanism, utilizing a two-stage safety system with shear bolts and resilient members to manage load thresholds.

Benefits of technology

This design reduces the risk of damage to the stuffer assembly, ensures high-quality bale formation by maintaining tine engagement, and minimizes downtime by allowing quick reconnection or replacement of affected tines, thereby protecting the tine bar and drive mechanism from overload.

Abstract

A stuffer assembly (24) comprises a stuffer chute (32) and a stuffer (34) for transferring crop material from the stuffer chute (32) into a baling chamber (6). The stuffer (34) comprises a tine bar (50) having a plurality of tines (38). Each tine (38) is slidably connected to the tine bar (50) to be linearly movable with respect to the tine bar (50) between an extended position and a retracted position parallel to a radial direction of the tine bar. A method accordingly comprises retracting a tine (38) from the extended into the retracted position in case of an overload.
