First, Lu Ban, the originator of architecture and carpenters.
1, woodworking tools
It is recorded in many ancient books, such as The Pearl, The Origin of Everything, and A Textual Research on Ancient History. He thinks that many tools and appliances used by carpenters were created by him, such as square (also called Lu Banchi), and the legends of tools such as Mo Dou, planer, drill and saw were also invented by Lu Ban. The invention of these woodworking tools liberated the craftsmen at that time from the original heavy labor, and the labor efficiency was doubled.
2. Ancient weapons
Hooks and ladders are commonly used weapons in the late Spring and Autumn Period. Mo Wen records that Lu Ban changed the hook into a "strong hook" for ship warfare. Chu used this device to fight a water war with the Vietnamese army. Hook the boat when it retreats, and push it away when it passes. "Mozi's public loss" records that he changed the ladder into a ladder that can stand in the air to attack the city.
3. Agricultural machinery and tools
The invention and adoption of advanced agricultural machinery is one of the important conditions for the development of ancient agriculture in China. Shiben said that Lu Ban made stones, and Wu Yuanqi Yuan said that he made hulling, grinding and milling machines, which were very advanced at that time. In addition, "Ancient History Examination" records that Lu Ban made a shovel.
Second, Mozi's mechanical manufacturing
Mozi is proficient in manual skills and can be compared with the craftsmen's bus class at that time. Mozi is good at guarding the city, and his ability and attainments in this respect have been fully reflected in the offensive and defensive drills such as Chu's defeat in attacking the Song Dynasty. He spent three years developing a flying wooden bird (kite, paper kite) and became the founder of ancient kites in China.
He is also an expert in making vehicles, and he can build a car with a load of 30 stones in less than one day. The car he built was fast, labor-saving and durable, which was appreciated by people at that time.
Mozi knew almost everything about the manufacturing technology of various weapons, machinery and engineering buildings at that time, and he had many creations. In Mozi, he introduced and expounded the city gate, the city gate and the suspended door structure inside and outside the city in detail.
The structure of defense facilities, the manufacturing technology of crossbows, oranges and various offensive and defensive instruments, and the construction technology of waterways and tunnels.
Extended data
Other outstanding craftsmen:
1, a new twill loom
He went deep into the production process, carefully studied the old twill loom and redesigned a new twill loom. The new twill loom simplifies the pedal and transforms the moving parts (that is, the shedding moving parts). Ma Jun changed the pedal to twelve nie. After such improvement, the new twill loom is not only more exquisite, simpler and more applicable, but also the production efficiency is four or five times higher than the original one.
2. Compass car
In the absence of data and models, Ma Jun conducted painstaking research and repeated experiments. Not long after, he finally made a south guide car by using the structural principle of differential gear. Ma Jun's compass, no matter how the chariot turned, always guided Woodenhead's finger on it, which attracted the admiration of the ministers of the Qing Dynasty.
3, keel waterwheel
After repeated research and experiments, he finally created a dumper, which led the water in the river up the slope and realized the people's long-cherished wish. This kind of rollover created by Ma Jun is "a hundred times more skilled than usual", which is extremely light and even a child can overturn it. It can not only lift water, but also drain water when it rains and floods.
