Keel blades as a chain, lying in a long rectangular slot, leaning against the river or pond. The lower sprocket and a part of the car body are submerged. When the sprocket is driven, the blade will wipe up along the groove and send water to the upper end of the long groove. This kind of continuous circulation can transport water to the place where it is needed, and can continuously take water, which greatly improves the efficiency, is convenient to operate and transport, and transfers the water intake point in time. The earliest application of chain drive in ancient China was rollover, which was a great improvement of agricultural irrigation machinery.
