China ancient agricultural machinery, introduce several main farm tools:
1. Cultivated land since Han and Tang Dynasties
Our country invented thunder very early, and used it to turn over the whole land, sow crops and carry out agricultural production. With the development of production, Reddy developed into a plow. But before the Warring States period, people only used stones, wood, bones and a small amount of copper soil preparation tools. Later, due to the emergence of Niu Geng and the rise of iron smelting industry, iron plows appeared in the Warring States period, and iron plows in the Warring States period were unearthed at Yanxiadu site in Yixian County, Hebei Province and Huixian County, Henan Province. The invention of the iron plough share is a remarkable achievement, which marks a new period of human social development and a new stage of human struggle to transform nature.
2. Ding cymbals, the seeder of Han Dynasty.
China had seeding machinery in the Warring States period. During the reign of Emperor Wu of the Han Dynasty, Zhao created and invented a three-legged cymbal that could play three lines at the same time on the basis of the one-legged cymbal and the two-legged cymbal. One cow pulls, one person leads the cow, and one person helps to plow the field, so one hectare of land can be planted in one day, which greatly improves the sowing efficiency. Emperor Wu of the Han Dynasty once ordered the popularization of this advanced seeder throughout the country.
3. Irrigation machinery. Keel water wheel
Keel waterwheel is one of the most famous agricultural irrigation machinery in ancient China. Dragon bone car is called rollover in ancient books. According to the records of the later Han Dynasty, this irrigation machine was invented at the end of the Eastern Han Dynasty. At first, water was irrigated by turning the wheel shaft manually. Later, due to the development of axle and the progress of machinery manufacturing technology, the keel waterwheel powered by animal power, wind power and water power was invented and widely used throughout the country. According to the different power, keel waterwheel has the following kinds.
4. Advanced grain processing machinery-water hammer and water mill
After grain is harvested and threshed, it must be processed into rice or flour before it can be eaten. China invented many grain processing machinery in ancient times, such as grinding, grinding, grinding, turning, rolling and so on. , and later invented the hydrodynamic hydrodynamic water mill, water mill. These machines are efficient and versatile, and they are important inventions in agricultural machinery.
Water mill is a kind of machine that uses water to grind rice, which appeared in the late Western Han Dynasty. Huan Tan's New Theory of Huan Zi in Han Dynasty (about 23 BC-50 BC) recorded water land.
