Abstract
Density control system for an agricultural baler having a baling chamber including a plurality of walls with at least one movable wall section, an intake duct leading into the baling chamber, and a plunger for compressing charges of crop material to a package in the chamber, an actuator for adjusting the position of the at least one movable wall section in response to an output of the density control system to vary the density of said package, wherein the density control system has a sensor for measuring the position of the at least one movable wall section, a comparator for comparing said position with a threshold position and a decision module configured to stop the movement of the actuator means when the position exceeds the threshold position.

A density control system for an agricultural baler, which comprises a baling chamber comprising a plurality of walls including at least one movable wall section, an intake duct leading into the baling chamber, and a plunger for compressing charges of crop material to a package in the chamber, an actuator for adjusting a position of the at least one movable wall section in response to an output of the density control system in order to vary a density of said package, wherein the density control system comprises
- a sensor configured for measuring the position of the at least one movable wall section, a comparator configured for comparing said position with a threshold position and a decision module configured to stop the movement of the actuator when the position exceeds the threshold position.
An agricultural baler comprising:
- a baling chamber comprising a plurality of walls including at least one movable wall section, a crop feeder for introducing charges of crop material into the baling chamber, a plunger for compressing the charges to a package of the crop material in the chamber, a density control system configured to vary a density of said package, and an actuator for adjusting a position of the at least one movable wall section in response to an output of the density control system,
- wherein the density control system comprises a sensor configured for measuring the position of the at least one movable wall section, a comparator configured for comparing said position with a threshold position and a decision module configured to stop the movement of the actuator when the position exceeds the threshold position.
A method for controlling a density of packages of crop material in an agricultural baler, which comprises:
- a baling chamber comprising a plurality of walls including at least one movable wall section,
- a crop feeder for introducing charges of crop material into said baling chamber a plunger for compressing the charges to a package of the crop material in the chamber,
- an actuator for adjusting a position of the at least one movable wall section in response to an output of a density control system in order to vary the density of said package;
- the method comprising the steps of
- monitoring a position of said at least one movable wall section via a position sensor,
- comparing said position with a predetermine threshold position;
- deciding to stop the movement of the actuator when the position exceeds the threshold position.
