Century Folk Art Museum Keel series Keel (dragon bone waterllft) also known as a "car", "bicycle", "water", "said keel". Machine for drainage irrigation. Because its shape is like a keel, named "keel series". The structure is made of wood for anti tank, tail water immersion, there is a ferry shaft. The other end is fixed on the banks of the little wheels, the gallows. When used to step on the moving wood, so that the big wheel shaft rotation, driven by the plate leaf blade scraping up the water, pouring in the higher terrain. Later and using water powered water to keel car overturned by bovine oxen pulling gears. The use of wind and wind to turn over. Guangdong and other places with a lighter, applied to the field ditch, called "hand to pull the car". structure The structure is made of wood for anti tank, tail water immersion, there is a ferry shaft.

Guangdong and other places with a lighter, applied to the field ditch, called "hand to pull the car". origin About keel series began in the Eastern Han Dynasty three inventor Ma Jun had to be improved. Since then has been playing a huge role in agriculture. "After the Han Dynasty, the official biography": "let Zhang and Ye Ting to bi lan... As... Rollover thirsty Ukraine, applied to the west, with a sprinkling of South Beijiao road." Li Xianzhu: "a locomotive overturned, with water; thirsty Uzziah, curved tube, the gas diversion also." "Three Kingdoms" in skill - Du Kui Song Peisong note cited Fu Xuan said: "in the city of Kyoto, and can park, with anhydrous irrigation is to make children, overturned, turn, and irrigation self cover, more into the list, its own 100 to often." The song "Meiyao Chen and sun side sou Si Cheng tools thirteen." water: "both the wheels turn, and if the Sichuan Hong yin. Shift work from Mei Ren Lin Yu, seedlings." The song "Wang Anshi Yamada long to crack" poem: "the keel has vomit dumb, Tian, as if." Jiang Jiong "song": "the bicycle transport truck transport. A radial spoke on v. Turning the water, such as purging jade. Cart two Zhang four, car one Zhang six. Small hand to hand, foot, foot heart car column two phase. The left foot to right foot, like treading water in Pinglu. High field and low field foot irrigation. Do not hesitate to work human resources, I hope autumn into the Huojia valley." The name comes from the folk keel series, "Spring Festival" on Lu You in the Southern Song Dynasty: "Ming Shui Tang car into the keel, it can look bumper." At present, the historical data, this is the earliest source. Keel series suitable for short distance, high water in 1 ~ 2 meters, suitable for use in plain areas, or as an auxiliary facilities of irrigation projects, from the canal directly to the farmland water. For water wells in the keel of the waterwheel is vertical, a flat wheel transmission device of water and two kinds of vertical wheel power conversion direction. It is generally placed in the water, the river, the lower tank and scraper straight water, using the chain drive principle, the human (or animal) as the driving force, driving cycle of wood chain flip, installed in the wood on the chain scraper can improve the river water along the shore, farmland irrigation. The waterwheel, to solve the irrigation problem, played a very important role. The first is the use of human keel series rotation, then the Chinese people have created a variety of water using animal, such as wind power and water power. Effect Since the Tang and Song Dynasties, irrigation, drainage and water supply canal, keel waterwheel is the most common use of water lifting machinery, especially in the southern Daxing farmland, the low head water lifting machine needs more common. The Yuan Dynasty Wang Zhen "agricultural book" draw a different dynamic keel series maps of the human hand, foot waterwheel has, waterwheel has animal carts, etc. three cart, keel series of Ming Dynasty Song Yingxing "Heavenly Creations" redrawing the. Beijing Museum of history China existing according to historical records, the proportion of 1:1 imitation model. Development Because the keel series is reasonable in structure, reliable and practical, so it can be handed down from generation to generation. Until modern times, with the widespread use of agricultural water pumps, it has completed the historical mission, quietly withdraw from the stage of history. As the keel series of irrigation equipment has now been replaced by electric pumps, but the waterwheel sprocket drive, turn the working principle in ascension, but have immortal life. Bucket dredger dredging take our coastal port often can see for example, that only a rotary dredging mud bucket, water from water tankers is born out of the turning plate. It sees a dredge, people seem to see the old keel series. Carriage The carriage is a horse drawn carriage, or manned, or freight. The carriage is very old, it is almost as long as the civilization of mankind. From nineteenth Century to, the carriage was still a very important traffic tool in urban traffic. People love the carriage of elegant and poetic love, take a leisurely carriage across the country road or the old streets of the city to visit friends. With the appearance of the train and the car, the wheels rotate faster and faster. At this point, the end of the golden age of carriage Chinese carriage history Anyang Yin Ruins archaeological excavations indicate that Chinese has used a chariot in the late Shang dynasty. The origin of the Chinese carriage has been a popular concern, but it is still an open question. In this regard, academic circles...
