In this report, Lu Ban described to Zhao Wuxian an incomparably brilliant future, a future built by hydrodynamic equipment. Pen % fun % Pavilion www.biquge.info

It was Zhao Wuxian who first proposed the concept of hydraulic machinery, but at the time, he was still focusing only on agricultural grains.

For the agrarian people, the most tedious but unavoidable work is the removal of the husk of the grain. The primitive method is to use wooden sticks and stone pestles to hit, so in the Spring and Autumn Period, there was a punishment that was "Chengdan Rice", which allowed prisoners to cook rice all day long, which shows that the people of the world are impatient but helpless about this work.

After Zhao Wuxian asked craftsmen to make stone grinding, the time for grinding rice and hulling was greatly shortened, and livestock could even be used instead of people to work. However, Zhao Wuxian, who had seen the rural water mills in later generations, was still insufficient, so in the first two years, he asked Lu Ban to try to make a water-powered mill.

In order to convert water into mechanical energy, it must be converted by a mechanical device, which should be the simplest round wheel, which is the "water wheel". The transverse water wheel rotates under the impact of the water flow, so it converts the potential energy of the water into mechanical energy and does work, its birth is the key link of the water power into the application field, and then the appropriate gear is installed, it can drive the stone mill to rotate.

The principle is deceptively simple, and the craftsmen who "make wood into a wheel" understand it as soon as they say it. But it is not easy to do, Lu Ban took the craftsmen to study in addition to making catapults, and it took several months to make the first water mill in the Linzhang School Palace last year, and it has not yet been popularized to the people.

After the water mill was made, the next thing that appeared was naturally the big cylinder car placed on the bank of the Zhangshui ditch not long ago. Unlike the horizontal water mill, the cylinder car is vertically driven, or rather, it is a huge vertical water wheel......

The two different water wheels are equivalent to the pre-technology of hydraulic machinery, and then it only takes a flash of lightning in Lu Ban's mind to copy more new inventions.

This time, Lu Ban only spent more than a month presenting two drawings named "Water Drain" and "Water Pipe" to Zhao Wuxian.

Zhao Wuxian really knew these things and didn't know why, after teaching Lu Ban the common sense in his stomach, it had only been a few years, and the apprentice's concept of mechanics had far surpassed that of the master.

Lu Ban is an extremely serious engineering school, the drawings are meticulous, and the descriptions are also detailed, so in Zhao Wuxian's opinion, it is a bunch of black and dense small characters, and Zhao Wuxian's head is big.

He carefully studied for a long time before he understood that this water drain is a blower device for iron smelting, and its driving force is hydraulic power, and through the crank device set up by Lu Ban, the rotary motion of the water wheel is transformed into the reciprocating motion of the connecting rod......

In short, the use of water power, can be done without manpower and animal power, can make the fan open and close, the smelting furnace for blowing, this far beyond the surging power of manpower, not only can liberate labor, but also can increase the air volume, increase the wind pressure, improve the temperature intensity of smelting.

This also means that Zhao can have better and more iron!

Zhao Wuxian was a little moved, and looking down again, the structure of the thing called "Water Pipe", the structure on the drawings looked much simpler than the water drain.

On the drawing, the transmission mode of the water mill is that the water flow impulses the vertical water wheel, and the short horizontal wood on the axle moves the tip of the mill to promote the head of the mill to fall together for pounding. Lu Ban said that in addition to the traditional processing of grain, if it can increase the speed of the gear, there are also a variety of uses such as pounding pulp and crushing ore.

And Lu Ban was even more daring to propose that a similar device could be used to forge iron blocks......

In the recital, he described such a picture to Zhao Wuxian: because of the impact of the water, a sledgehammer raised high under the drive of gears and belts slammed into the iron block on the anvil! This is repeated thousands of times, and the iron that usually requires a blacksmith to temper for several days may take half an hour to take shape!

At that time, the forged steel will no longer be a magic weapon hidden in the hands of the nobles, but will become the standard weapon of the army......

"Isn't it a hydraulic hammer depicted in the public loss class!?" Zhao Wuxian was stunned.

……

According to Zhao Wuxian's knowledge, in the original history, before the advent of the steam engine, the largest kinetic energy that human beings could use was water power.

In China, the earliest use of water power should be in the Han Dynasty around the time of the Common Era, when a series of automatic machines sprung up like mushrooms after a rain, promoting the progress of agriculture. In Europe, the earliest record of the use of water-powered millstones to process grain was in the first century BC during the ancient Greek period, and by the time of the Roman Empire, water-powered sawmills and grinders were said to have been used to cut stones......

As for the pinnacle of the use of hydraulic power, it was the hydraulic hammer of the late Middle Ages.

With hydraulic forging hammers, it is possible to quickly mass-produce a large number of iron products, such as high-quality and cheap iron armor, iron weapons, as well as iron anchors and large iron plows.

However, to achieve this leap, Zhao Wuxian felt that Lu Ban must have been prepared in his heart, otherwise with his pragmatic character, he would not just put forward such an idea at the end of the song, but would have to set the final production deadline. This probably means that even the scaled-down model test, Luban was unsuccessful.

To make a simple comparison, the water mill is a wooden hammer that slowly smashes rice, more than a dozen times per minute.

Hydraulic hammer forging is the iron hammer smashing iron at a speed of 200 times per minute......

Not to mention the requirements for materials and the size of the machine, as long as you have studied physics a little, you will know how big the power gap is needed. But the speed of water is so large, so you have to work on the machinery driven by the water wheel, make them more complex, use less force, and get more power!

In this regard, Zhao Wuxian, a half-layman, couldn't help it, so he could only let Lu Ban do it.

So Zhao Wuxian approved a red hook in the newspaper and allowed Shaofu to allocate a sum of money to let Lu Ban start developing water drains and water pipes.

In his review opinions, he suggested that Lu Ban divide the craftsmen who studied new inventions under his command into several batches, a group of industrial and agricultural machinery, and a group of war equipment, each with its own specialty. It is divided into many groups that specialize in overcoming different technical difficulties, allowing them to compete with each other and promote efficiency. In terms of water milling, it is not a one-step machine, first to make the zero generation machine of rice, then to make bamboo to make pulp, to crush ore, and finally to wrought iron.

How many years will it take to see the effect?

Zhao Wuxian thought that even if he broke through one layer in ten years, he would be satisfied if it was made thirty years later, reaching the level of the thirteenth and fourteenth centuries in Europe......

What's more, in addition to water drainage and water mills, there are many hydraulic machinery that can be developed, sawing wood, cutting stones, and water spinning wheels, etc., are good things for the benefit of the country and the people. During the Spring and Autumn Period and the Warring States Period, wars were frequent, the population was sparse, and the labor force was severely insufficient, so Zhao Wuxian urgently needed other ways to improve production efficiency.

These things have to be handled by Lu Ban, and Zhao Wuxian can't be too anxious, urging too tightly, for fear of exhausting this genius to death.

"It's really my blessing to get Lu Ban...... Because of this, Zhao Wuxian tolerated Lu Ban's slightly irritable and radical temperament, because for Zhao, it can be said that the public loss class is the primary productive force......

"It seems that the matter of cultivating high-level craftsmen needs to be put on the agenda urgently." Zhao Wuxian heard the sound of the watch outside, the hour had just passed, and on the case, there was only one piece left, he sighed, pinched his eyebrows, and forced his exhaustion to open it and look at it.

After all, Ren Zhang's writing is elegant and handsome, and it should be regarded as appreciating calligraphy.

However, without looking at the two lines, a trace of anger flashed in Zhao Wuxian's eyes, and he sneered: "Taoist disciple, you are really naïve!" ”
