Firstly, use mechanical ventilation to send the grain to food stored grain box at certain height through the pipeline. Then the grain would flow grain stored pipeline with controlled door to automatic platform meter. When the grain flows to a certain weight, automatic platform meter would deliver a signal. The implementation components work to shut off the food pipe valve. At this time, automatic weighing process ends. In the figure, the photodiode 2CU2B is installed on the automatic platform meter to receive the signal outputs during the weighing process. Such signal depends on whether the status of meter’s shaft has covered signals from optical signal light source or not. Optical signals received by photodiode would be amplified through the line to control the relay. Then the implementation components are controlled to realize the purpose to automatically transfer grain.
