Chapter 60 Waterwheel
Qin Yao stayed at Carpenter Liu's house until two or three in the afternoon. After confirming all the details, she drew a scaled-down detailed drawing for him before going home with a growling stomach.
The sunshine is just right at noon. After harvesting the wheat in Liu Dafu's family's field, wheat stalks are already being burned. At a glance, the fields in the village are full of busy farmers.
The large piece of fertile land by the river to the east of the village belongs to Liu Dafu's family. Every year when spring plowing comes, villagers come to the house with chickens and ducks, hoping to rent his family's land for farming.
Qin Yao remembered Old Man Liu's suggestion to rent the fertile land of Liu Dafu's family for farming as early as possible.
But now, whenever she thinks of the exhaustion of working in the wheat fields a few days ago, all the cells in her body are screaming: Run!
Forget it, there are still some days before spring plowing, let's get the hydraulic stone mill out first and check the situation. If the situation is not good, it's not too late to go find Liu Dafu.
With an idea in mind, Qin Yao got busy with her hydraulic stone mill.
She first cleared a piece of flat land by the bridge on the north river bank near her home.
Then she told Qin Yao to remember to post a rule and tell everyone that they were waiting to use her water mill.
This is the first step. The next step is the stone grinding and the splicing of the bearings and bearings of each part.
Liu Guolang jumped up from the crowd and asked, "Ms. Qin, would you like to release this water mill for everyone's convenience?"
Then he punched a hole in the center of the millstone, installed the rotating shaft and wooden handle, and a large mill was ready.
Liu Ji was more excited than anyone else and ran home in a hurry to get wheat.
The adults dispersed the children who came over. Under Qin Yao's command, they put the waterwheel into the river she had prepared. The base was filled with stones, and it started to rotate steadily in the water.
Qin Yao went down to the river, removed the big rocks blocking the river, and ran ashore quickly.
Qin Yao quickly ran over to look at the millstone. Maybe it was because of the large flow of water at the moment, and the speed was quite fast. "Really?" The village chief came over curiously, and everyone made way for him.
The villagers thought about it and realized that the water mill is indeed very simple now. It doesn't even have a shed. If it rains, the food will be damaged.
The village chief and Liu Dafu were attracted by the excitement here. Liu Ji lit a torch from home and took it down, and there was light in the open space.
“It's turned around! It's really turned around!” Liu Carpenter shouted excitedly.
"It's too late today. Let's go home first. I haven't finished the water mill yet. I'll finish it in two days and come up with some rules before letting everyone know."
The main reason is that I want to know what Qin Yao has done as soon as possible.
After the assembly was completed, the sky had darkened, leaving only a sliver of orange sunset on the horizon.
Qin Yao said that she had read it in a book, and by the way, she tested everyone's willingness to pay to use their own water mill.
Liu Ji immediately tugged on Qin Yao's sleeves. For such a good thing, you must charge more royalties.
At the same time, news came from Carpenter Liu that all the waterwheel parts had been produced, and someone was sent over to ask her to assemble them together to avoid making mistakes.
You only need to send one person to keep an eye on it and pour the grain into the stone mill, and the people who were originally turning to grind the mill can be freed up to do other things.
"Crash!" Suddenly, the river water poured into the narrow river channel, forming a strong impact force. The water wheel started to rotate faster and faster, vigorously driving the bearing shaft to rotate, and transmitting the force to the handle above the millstone. The millstone slowly Turn slowly.
At this moment, they saw her and Carpenter Liu carrying the waterwheel and other things towards the river bank, and they all followed them curiously.
Qin Yao hadn't thought about how to set the price for a while, but seeing that many people were eager to try it, she responded loudly:
After a while, the ground wheat grains fell out. Qin Yao pushed them with her hands, and then they fell into the wooden trough next to the stone mill and automatically fell into the empty bucket along the slope.
“Here comes, here comes the wheat!”
By the time Qin Yao and his wife arrived at the river, everyone in the village who had time to do so came.
Throughout the day, apart from eating, drinking, and sleeping, the rest of the time was spent banging on the stone with a pickaxe.
It would be much easier if Qin Yao's water mill could be used.
Qin Yao took the wheat, grabbed a handful and put it into the hole in the middle of the stone mill, and immediately heard the crunching sound of grinding.
He saw with his own eyes that Qin Yao had been tinkering by the river for five or six days, and today he actually built such a big waterwheel and even made the millstone spin by itself. How miraculous this is! It was enough for him to brag for half a year.
After asking, he was afraid that Qin Yao would think that he was using it in vain, so he immediately added: "I won't use yours in vain either. Just tell me the rules. I think everyone will be happy to do it."
The village chief couldn't wait for Qin Yao, who was so slow, and personally scooped up a ladle of wheat and poured it into the mill.
Then he went to the lower reaches of the river and brought back two boulders weighing several hundred kilograms.
The bearing shaft was also finished. The two couldn't wait to see the effect. After chewing a few mouthfuls of dinner, they carried the water wheel and the bearing shaft to the river.
Qin Yao went over after breakfast, and together with Liu Carpenter, they spent the whole day in his yard, building a waterwheel as tall as a man.
Night has fallen, the torches by the river shine brightly, and people's surprised voices can be heard from time to time in the center.
Someone wanted Carpenter Liu to make one for his own home.
“This grinding is faster than that of a human being, and it's effortless. Madam Qin, how did you come up with this good guy?”
The villagers were having some free time after dinner. They saw Qin Yao knocking by the river these days and were curious about what she was doing.
Qin Yao nodded, smiled, and asked Liu Ji to go home and get the freshly sifted wheat.
Liu Dafu wanted to use it the most. His family had a lot of grain, and grinding it alone would be tiring, so he hired five people to help grind the grain.
But the number of villagers on the bridge not only did not decrease, but actually increased.
Carpenter Liu told him: "To make such a water mill, the wood processing fee is at least two taels of silver, not counting the two large millstones. Mrs. Qin went to the river to find big stones and took them home and chiseled them out with her own hands. "
He actually knew how to pick up an empty bucket.
After beating like this for five days, two millstones with a diameter of 80 centimeters and a thickness of 20 centimeters were produced.
No one else can get involved in this process, only Qin Yao and Liu Carpenter can operate it.
Fortunately, Qin Yao is very strong, otherwise one person would not be able to lift these heavy wooden piles.
The grains grinded for the first time fell out, and after grinding them twice more, they turned into fine flour.
Liu Ji rushed down, carrying two buckets in his hands, one empty and one full of wheat.
After the assembly was completed, Qin Yao shook it to make sure it was stable, then personally lifted the boulder that she had placed by the river in advance, blocked the river with the big stone, causing the waterwheel to stop turning, and connected the other end of the stone mill with the wooden stake. Put the water wheel together and use wooden blocks to insert into the gaps and knock them tightly.
People from the Liu family's old house were also among them. Qin Yao didn't even need to say hello, her brothers and sisters-in-law took the initiative to come over and help.
The villagers immediately gave up the idea of building a water mill for their own homes.
What can you do with those two taels of silver? Make a water mill? I'm afraid it's crazy!
