Abstract
A grain handling system comprises a valve device for controlling a flow rate discharged from a downstream end of at least one flow passage. A volumetric weight measuring device measures the weight per unit volume of the grain delivered toward the valve device to generate a volumetric weight signal. A computer generates a control signal on the basis of the volumetric weight signal. A drive device drivingly connected to the valve device is operative in response to the control signal to drive the valve device so as to allow the grain discharged from the valve device to be controlled in terms of weight unit.
Claims31
A grain handling system comprising:
- at least one flow passage defining means for defining a grain flow passage having an upstream intake end and a downstream discharge end so as to allow the grain to flow along said grain flow passage from said upstream intake end to said downstream discharge end,
- valve means disposed in communication with said downstream discharge and of said grain flow passage for controlling the flow rate of grain discharged from said downstream discharge end;
- volumetric weight measuring means for receiving the grain to be delivered toward said valve means and for measuring weight per unit volume of the received grain under stationary condition to generate a volumetric weight signal;
- computer means connected to said volumetric measuring means for receiving the volumetric weight signal therefrom to generate a control signal on the basis of said volumetric weight signal;
- and
- drive means drivingly connected to said valve means and connected to said computer means, said valve means being operative in response to said control signal from said computer means to drive said valve means so as to allow the grain discharged by said valve means to be controlled in terms of weight unit.
