Abstract
A device to measure the volume and weight of a harvested grain crop during the harvesting of the grain crop with a weight measurement member including an elevator for moving grain from a lower elevation to a higher elevation with the elevator having a rotatable belt and a set of paddies thereon for moving grain from the lower elevation to the higher elevation with a torque sensor to determine the increase in torque on the shaft as a result of having to raise the kernels of grain from the lower elevation to the higher elevation and an acoustic volume measurement member to obtain information on the depth of the grain that is correlatable to volume of the harvested crop.
Claims5
A method of measuring the yield of a standing crop comprised of stalk and kernels as the standing crop is harvested comprising:
- cutting the standing crop and separating the kernels of grain from the stalk;
- elevating the kernels of grain from a first level to a second level;
- and
- measuring the mount of energy to raise the kernels of grain from the first level to the second level and correlation of the amount of energy to raise the kernels of grain from the first level to the second level with a reference to determine the weight of the kernels of grain lifted from the first level to the second level.
