The design of the waterwheel is simple, Wang Defa casually drew the renderings of the waterwheel, combined with the flow rate of the stream, and felt that the power of the waterwheel was insufficient. Pen % fun % Pavilion www.biquge.info

Zhang Guoan also calculated, it is indeed insufficient power, and it is not possible to increase the flow rate of the stream.

There is a way to raise the water level of Hongshui Creek.

Wang Defa went directly to discuss with the craftsmen they had recruited in advance, and assigned them some additional work, asking them to add railings to the river at that time, and then place straw bales and stones or something, and artificially raise it to a height of one and a half meters on the river surface, which is almost the same, and change the waterwheel into a torrent impact rotation.

You can add some more wages to the craftsmen.

In order to build this Hongshuixi Industrial Park in the Great Song Dynasty, they hired almost all the people from all walks of life in the county, carpenters, plasterers, stonemasons, blacksmiths, and the four great craftsmen arrived, and a large group of people were busy all day long.

At this time, the north bank of Hongshui Creek has become a small construction site.

In their design, this place should be built into a water slab house first, and then the work and life of the workers will be here for the time being.

They showed the drawings of the board house they designed to the craftsman, and after reading it carefully, the craftsman of the Song Dynasty thought about it.

The houses to be built by these overseas merchants are obviously not legal, and I have never seen such a long house shape, but their structure also looks very simple, and when you think about it, you can understand that they are all made of wooden planks, which is very easy.

They shipped the raw materials directly and started to prepare the materials.

The wages given to them by this host family are very high, and their enthusiasm goes without saying.

The plank wooden house is easy to build and the price is cheap.

Of course, fire prevention in the future is a big problem, but it is enough for them to use it for a stage.

When Wang Defa and Zhang Guoan were on their patrols, they watched them laboriously pulling large sawn plates, and saw the primitive and backward nature of their tools.

Wang Defa said: "The speed of construction cannot be improved------

Zhang Guoan said: "Don't worry, as long as they are doing it, it will be completed within a month or two."

Let's go recruit our own mechanic students first, that's the big deal. ”

The Great Song Dynasty of this time and space already has a labor market for freelancers to find work.

During the Southern Song Dynasty, the number of people returning from the north to the south continued to increase the number of idle laborers under the management of the Great Song government, which increased the employment pressure on the society.

They have a fairly clear understanding of this reality, so they are more supportive of the common people to set up workshops and other behaviors, and they also strongly encourage the behavior of some large households to hire workers.

This has led to an increase in freelancers, and of course, there are also some farmers who work part-time seasonally.

In the Great Song Dynasty, you have to pay taxes regardless of whether you win or lose, but when you hire someone to pay your salary, you don't have to pay personal income tax.

It's okay, the Great Song government is also clear-headed.

They walked around the labor market.

In fact, there is no listing there, but there are some people standing on the edge of the so-called market, and they know each other quite well.

They didn't pick adults, but while looking at their faces, they asked their ages and picked more than a dozen descendants, including locals, outsiders, and people returning from the north.

When these young people heard that the owner of the Hongshuixi Industrial Park was not only in charge of food, housing, but also clothes, and most importantly, high wages, they happily agreed.

As for the agreement of the lord to ask them to obey the discipline, if they do not obey, they will repay the lord's wages twice, and this is also normal.

Wang Defa said to Yalang Ma Yun: "You tell them that in the future, I will pass on their skills in the world, and ask them to swear that they will not pass them on without my consent." ”

Zhang Guoan said to Yalang Ma Yun: "In the future, I will teach them to cultivate the secret seeds of the world, and ask them to swear that they will not pass it on without my consent." ”

In fact, the two of them discussed it, and they regarded them as students in a technical school, and they had to teach them some basic skills, otherwise there would be no way to carry out future work.

As for the question of whether to keep it secret or not, it doesn't matter at all, it's just to strengthen the sense of mystery or to make the other party pay attention to it.

Those young descendants have drawn a pledge of recognition.

Zhang Guoan and Wang Defa were happy to find that the city official actually filed this employment behavior, what does this mean? It shows that I confirm that your contract is true and valid!

As soon as they arrived home, Wang Defa had to give them a lesson first, where could this time be wasted.

They had already packed up a room and asked the county carpenters to build a few sets of bunk beds, telling them not to decorate us, we were in a hurry, and the carpenters had a lot of work.

The carpenters were happy, and the price of the handiwork was the same, and they did not want to bother.

They also made long tables and benches.

As for luggage, it's simpler, and there are several cloth shops in the county

Nothing is difficult to solve, but language communication is a bit difficult.

But don't be afraid, leave Yalang Ma Yun in class for the time being, a little bit of translation.

Yalang Ma Yun is happy, this is a long-term job, making money steadily, and there are often rewards.

Wang Defa started classes quickly, and he didn't care whether the students were adapted to teaching life or not.

He asked the students to call him Professor Wang. Of course, this is not a spoof, at this time, the professor is the meaning of the teacher, and Wang Defa himself likes this title.

After the students complied with the arrangement and sat down in a disorderly manner, they first looked at the room curiously.

They saw Professor Wang standing in front of a wooden shelf with a lot of rice paper pasted on it.

Professor Wang Defa opened his mouth and asked, "Everyone has seen a wooden waterwheel, right?" The flow of water pushes it, and it can produce a turn, and then ...... You see, the wind can also push ......"

The students were stunned at first, is this Professor Wang a fool for me?

However, the content that followed was interesting.

The students saw gear drive, chain drive, belt drive and other transmission methods...... I have seen it for a long time.

During this period, Professor Wang Defa used a charcoal pen to draw pictures on rice paper and explain at the same time.

It's all very simple, even Yalang Ma Yun can understand it.

After the first class, they could play for a while, and they all ran to the hills behind to play, waiting for Professor Wang to call them.

After class, Professor Wang Defa drank cold and said to Zhang Guoan: "The receptivity of these students is okay, sure enough, you have experience, and the level of people's IQ can really see some ...... from their faces."

Zhang Guoan said modestly: "How many years have I been a teacher, how can I have some experience." Some students can tell at a glance whether they are smart, naughty, or unruly, but they can't generalize. ”

The second class was a bit of a hassle.

No matter what Professor Wang Defa says, the students don't understand why the big gear rotates slowly, while the small one rotates quickly, not to mention the two-stage transmission.

The classroom discipline was very good at first, but in the first class, they were really curious, and they were recruited to work for three years, but they didn't have to work at first, but had to attend classes...... And if you eat it for nothing, you will get a few sets of clothes for nothing.

It's like an obedient book in a teahouse!

At this time, those students were familiar with each other, and Professor Wang Defa's speech seemed to be boring, they began to wander, and even began to talk.

Professor Wang Defa could almost call out the names of these people at this time.

"Gu Jianshan, if you speak secretly, I'll kick you to death!"

"Wu Jie, where are you looking? Do you see how serious Wu Di is in listening to the class? ”

"Zhang Depei, Bao Wei, you two dare to make small moves below, stand up! Stand in the back and don't get in the way of Mei Lezhi and Mu Mu listening to the class......"

"What is the matter with you, Horseside? Okay, let's go to the toilet...... Okay, Guo Beyu, you can go too......"

Professor Wang Defa quickly gave up the oral science popularization of gear speed ratio, he did not dare to test their mathematics and other science subjects in advance, but only started from the overall situation, and the teaching goal designed by Zhang Guoan must have his reason.

He finally found a carpenter, and spent a lot of money, so that he could carve two wooden gears little by little, one larger and much smaller, and of course the gears had to fit.

In this way, he made this group of people really see the phenomenon of slow input speed and fast outgoing speed.

At that time, when the model was turning, even Yalang Ma Yun watched it with relish, and the students were convinced, it turned out that this had a lot to do with the number of gears!

In the third class, Professor Wang Defa brought a charcoal stove, on which was the long-spouted copper kettle they had ordered from the copper blacksmith, but of course they could not find the white iron sheet at this time.

After a while, the water in the spouted kettle boiled, and a puff of white smoke came out.

Professor Wang Defa said: "Do you understand? ”

Everyone laughed, isn't that normal?!

Professor Wang Defa folded a windmill with white paper in advance, and when the steam flow increased, he put it on, and the result was normal, it rotated.

Professor Wang Defa walked around the so-called classroom with his hands behind his back and a peeled branch in his hand, and then said: "Think about it, as long as the water is boiled, can the steam blow the wheels around?!" ”

"Exactly, exactly!"

"If the copper kettle is made bigger and stronger, will the steam spewed out be more powerful and can blow the wooden wheel?!"

“…… Exactly, exactly......"

Professor Wang Defa pointed to the copper kettle with a branch and said, "From now on, we call it a steam boiler!" ”

Then he pointed to the long mouth and said, "This is called a steam pipe......

Then he pointed to the spinning windmill and said, "This is called a steam engine!" ”

At this time, the long-spouted copper kettle on the charcoal stove was heated more and more, and the water in its stomach rumbled non-stop, and the steam flow from the long-spouted mouth became more and more powerful, directly knocking down the paper windmill.

Professor Wang Defa said: "Look, if we use a wooden wheel at this time, we can rotate!" What if it was a little more powerful and replaced with iron wheels?! ”

Professor Wang Defa glanced at the students and exclaimed:

"Gu Jianshan, you speak again, you have something to stand up and say!"

Gu Jianshan was a little smaller, but his eyes turned quickly, and he said, "I don't understand, even if this iron wheel turns, what's the use?" ”

Professor Wang Defa was furious in his heart, this is still smarter?!

But he suppressed his breath and asked everyone in a low voice, "Can any of you tell what the use of this iron wheel is when it turns?!" ”

Zhang Depei opened his mouth and said: "In the first class, the teacher taught that what can be transmitted is better for grinding rice!" ”

Wu Di also opened his mouth and said: "It can also be used to carry water!" It can wrap the rope around it, and the bucket underneath can be lifted......"

Hou Dongfang shouted: "You can also pull coal ...... in the coal pit."

Gu Jianshan suddenly figured it out, can this still be used on the car and boat, he has seen it, why didn't he think of it at the time?

He sat down dejectedly, yes, very simple thing.

Professor Wang Defa is very happy, and he can still think of something, even if there is a smarter one, it is not disappointing, let alone two or three.

Unexpectedly, a bigger surprise was behind her, so Mei Lezhi stood up and said, "Professor Wang, what if you draw that steam into the cold water in another basin?" ”

Professor Wang Defa was happy and said, "Mu Mu has raised his hand, you can also talk about it......"

Mu Mu whispered: "Then when you take a bath in the future, you don't need to boil water anymore......

Professor Wang Defa knew that in this time and space, the common people of the Great Song Dynasty had the habit of taking hot baths. Especially in that Lin'an Mansion, there are many places where they can take hot baths.

Professor Wang Defa said: "Is it better to heat with this steam, or to boil water?" ”

"It's good to use steam, if you want to be cooler, you can use less steam, if you want to be hotter, you can use more."

Professor Wang Defa asked reluctantly, "What else can be done?" ”

Gu Jianshan finally became smarter, he suddenly thought and said, "It can also be used to boil sugar!" Boil salt! ”

Professor Wang Defa finally laughed out loud and asked, "How did you come up with it?" ”

Gu Jianshan began to say respectfully at this time: "A certain person from Chongqing Prefecture, in the second year of Jingding, the Tartar war was chaotic, and he came here with his family, and he had seen boiling sugar and salt. ”

"If you use it to boil sugar, boil salt, what do you think it will do ......"

Gu Jianshan looked at the increasingly loud steam current, and said cautiously: "I'm afraid it's not hot enough......

"Gu Jian Mountain, don't worry, I will make it bigger, stronger, and burn more violently, what will happen to those?"

The sweat of Gu Jian Mountain had come down, and at this time, the house was also filled with the smell of water vapor.

Gu Jianshan said: "Yes, it will be cleaner." ”

Mu Mu added in the following novel: "You can also get hot and cold at will......"

He immediately added: "Yes, you can also be as hot and cold as you want......

At this time, Ma Yun, who was next to him, was disdainful, such a simple truth can also be called a "lesson"?

Professor Wang Defa suddenly smiled and said: "Some people are afraid of it and say that it is a demon and a monster, do you believe it?" ”

Everyone laughed, and even Yalang Ma Yun showed a mocking look, what kind of foolish man and foolish woman think like this?

There will be people in the world who are afraid of this thing, it is really the big in the world, and there is no wonder.

Yalang Ma Yun sincerely hopes that Professor Wang Defa will take more classes, so that he can earn money by sitting all day and just moving his mouth.
