초록 ▼

A weighing system for measuring the weight of a material carried on a conveyor assembly. The weighing system is compatible with conveyor assemblies wherein either the pitch angle, the roll angle, or both, is variable. The weighing system includes a load cell that measures a force borne by the support member of the conveyor assembly. One or more clinometers are used to define the angular position of the conveyor assembly. The number of clinometers is great enough to fully define the pitch angle, the roll angle, and the direction through which the measured force acts. The measured angles, the measured force, and a tare weight of the conveyor are used to calculate the weight of the material. The weighing system may be adapted to measure a flow rate of the material. Furthermore, the conveyor assembly may be mounted on harvesting equipment in order to measure crop yield data and to generate maps depicting the crop yield distribution over a field.
