Abstract
Yield monitor apparatus and methods for a forage processing machinery are provided. The yield monitor measures a forage yield by variously measuring a forage impingement force, a forage volume flow, a forage volume increment accumulation, or a forage processing machinery drive load. The yield monitor may generate a yield amount, with the yield amount capable of being stored and displayed to a forage processing machinery operator. Alternatively, the yield monitor may generate a groundspeed control signal that is used by the forage processing machinery to control a forage processing machinery groundspeed or other forage processing machinery parameters.
Claims8
A yield monitor for a forage processing machinery, comprising:
- a deflector shield affixed to at least one force measuring device, with said deflector shield being positioned below a cutter head of a forage harvester to guide a forage stream leaving said cutter head, said forage stream impinging on said deflector shield and said at least one force measuring device, with said at least one force measuring device generating a farce signal substantially related to a forage mass flow rate;
- a computer that receives said force signal and generates a yield amount based upon said force signal, a forage processing machinery groundspeed, and forage processing machinery intake parameters.
