A Method and System for Determining the Load on an Element of the Drive System of a Plunger in a Baler.

摘要

System and method of determining the load on an element of the drive system of a plunger of an agricultural baler, and to use thereof for controlling such balers. A value representative of an estimate of the load on an element of the drive system of the plunger is determined, based on combining an obtained value representative of the load on the plunger with obtained position information of the drive element relative to the plunger.

主权项

1. A square baler that forms rectangular bales of agricultural crop material, comprising
a plunger that compacts harvested crop material by a reciprocating movement in a fore-and-aft direction within a bale-forming chamber, a drive system that drives the reciprocating movement of the plunger, and an electronic device that determines a value representative of or an estimate of the load on one or more elements of the drive system, the electronic device comprising
a first port for obtaining a first value representative of or an estimate of the load on the plunger;a second port for obtaining a second value representative of or an estimate of the position of one or more elements of the drive system, relative to load on the plunger; and a computation unit that determines the value representative of or the estimate of the load on one or more elements of the drive system based on the first and second value.
