Jiang Zhennan looked at the blueprint and pondered for a while. He then said, "Miss Yue 'Er, this kind of... This threshing machine is time-saving and energy-saving. How is that?"
Lin Yuelan went over and pointed at a few nodes. "this kind of threshing machine has a bed in front to store grains, gears on both sides, and a rolling core in the middle. There are many fine nails inserted in the rolling core. The threshing is done by them, and the pedal is stepped on. The moment the pedal is stepped, the gears on both sides would turn, and the rolling core would start to roll. Then, you would just have to put rice on top of it to twist it. However,"
At this point, Lin Yuelan paused for a moment and gave Jiang Zhennan a tired look before she continued, "To make sure the gears spin quickly, we have to use oil." Modern people used engine oil or diesel.
Oil was a little expensive, and most people were reluctant to use it. However, to Lin yuelan, money was not a problem.
