Grain metering device for combine harvester

Challenge

Our client approached us for a device that could be added to their combine harvester range and provide yield data in real-time during harvest

Approach

• Grain is difficult to measure in real-time due to the non-uniform density of solids
• We assessed different methods of measuring mass flow rate taking into account the dusty and unpredictable, mobile environment
• Mathematical and analytical modelling helped to validate the concept
• A vibrating plate system delivers the force required at a flow rate of one kilo per second

Benefit

• The client is now able to provide their customers with real-time yield data
• Their customers will be able to tailor chemical and crop care programmes on an area by area basis
• Customers receive a geo display depicting yield levels for precision dosing and irrigation
