Harvester Automation System

Application

The client has developed a folding auger arm to extend the reach of the arm in the hopes of reducing soil compaction during harvesting. The folding arm is actuated by 3 hydraulic cylinders working in unison.

Solution

Precise control of the position of each cylinder was required for smooth extension and retraction of the arm without causing any damage to the system. Two of the cylinders incorporated internal position sensors from Balluff and installed by Nordon. The third cylinder was longer, so an external draw wire was used instead.

Key Features

• Movement of system controlled by Danfoss MC024-120 controller and a PVG32 valve.
• Controller and valve combination allowed ne control of ow to each cylinder at different stages of extension.
