According to the quantity of purchased rice, such as 15kg, you can push 15kg button, to make the tractive magnet which controls the counter poise move, then the 15kg counter poise automatically falling; according to the kinds of japonica rice or indica rice, to push kinds button, it can control the food-importing port of japonica rice or indica rice gate open, then the rice flow to the funnel of platform scale. Fixing source bulb and light-sensive diode in the vane of platform scale, ater it is amplified, the relay will take action to drive tractive magnet work. When it is nearly the wanted quantity, the steelyard will close the food-importing port, the rice is added from the small gate; then the steelyard rises slowly, when it reaches the standard, the light source is cut off, relay closes the small gate, the standard singal light on. To push the released rice button, the electromagnet of platform scale's delivery gate pulls up, then the rice will flow into haversack.
