EMBOLO ALTERNATIVO, PARA FORMACION DE BALAS DE HENO, DOTADO DE SISTEMA DE CONTROL DE UNIFORMIDAD DE LAS CARGAS.

摘要

A hay baler (10) for producing large rectangular bales (17) picks up crop material (16) directly underneath the fore-and-aft bale chamber (20) of the machine as the baler advances across the field and stuffs charges of the picked up hay into the overhead chamber for compaction by a fore-and-aft reciprocating plunger (34). Sensors associated with the two laterally spaced driving arms (36, 36a) of the plunger (34) detect the extent of uneven crop loading into the baling chamber through measuring any differential in compressive loading on the arms (36, 36a) and cause a visual display in the cab of the towing tractor which indicates the direction and magnitude of steering correction which is required to reestablish even loading of the baler. A micro-computer (70) receives the outputs from the driving arms; (36, 36a) processes the same and appropriately activates the display monitor (602) in the cab.
