Yield monitor apparatus and methods for a forage processing machinery are provided according to the invention. 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.

Yield monitor for forage crops

A thermal mass flow meter associated with an inclination sensor that detects an angle of inclination of at least one portion of a thermal mass flow sensor relative to at least one reference axis. Based upon the detected angle of inclination, the output signal of the mass flow meter that is indicative of the mass flow rate of fluid through the sensor may be compensated to account for any inaccuracies relating to the orientation in which the mass flow meter is installed. Inaccuracies for which compensation may be provided include thermal siphoning effects and fluid buoyancy effects. By compensating for such inaccuracies, the mass flow meter may be used in any orientation, and/or may be used in non-inertial (e.g., accelerating) environments. The flow meter may be used as a stand alone device, or incorporated in a thermal mass flow controller.

An agricultural harvesting machine, such as a combine harvester comprising a header for collecting crop material from a field, an auger and straw elevator for conveying the collected crop into the harvesting machine and a threshing and cleaning system. The harvesting machine is equipped with a sensor for sensing the flow rate of at least a portion of the collected crop. The sensor is provided with dampening system for dampening mechanical vibrations caused by the header, the auger and the cleaning and threshing system. The sensor comprises an idler sprocket that senses the torque transmitted by a chain transmission upon a conveyor, such as the transverse conveyor of a header. The dampening system involves an inertia wheel attached to the driving sprocket of the chain transmission, an elastic coupling and further inertia wheel driven by the primary drive shaft of the header.

The disclosure relates to improved methods of designing surfaces whereby to minimize the effects of changes in the coefficients of friction between so-called bulk fluids and the surfaces. The disclosure also relates to surfaces designed in accordance with the methods. A device embodying the invention, for metering the mass flow of bulk material, such as grain or other crop material, comprises a sensor member with a curved surface installed adjacent the outlet of a conveyor. The sensor member is mounted for pivoting about a transverse axis and is subject to a moment resulting from the material flow along its surface. A spring means is provided to keep the sensor member in zero load position. The displacement of the sensor member is proportional to the mass flow rate. Changing friction coefficients μ between the bulk material and the surface will affect the flow pattern therealong, but an array of length and/or inlet orientation angles can be found relative to which the measured moments remain substantially insensitive to these flow changes. Such metering devices may be used in grain and forage harvesters, wherein they need less recalibration under varying harvesting conditions.

In the field of mass flow measuring apparatuses, it is known to provide a sensor member for the establishment thereon of streamline flow of bulk material, in which the sensor member design is optimised in order to minimise the effects of changes in the coefficient of friction between the bulk material and the sensor member. The invention relates to improvements in the construction of the measuring apparatus, whereby two mechanical quantities (such as a pair of forces; or a pair of moments) may be measured to provide additional data on the flow process. In particular, it is possible to determine an exit velocity value v e that is indicative of the momentum of bulk material in the sensor member.
