After three days, one was put together, consisting of four wooden wheels clamped by five logs. Pen, fun, pavilion www. biquge。 The watermill production of info was formed. The diameter of the waterwheel reached more than 5 meters. The width is more than three meters wide. The central axis is run through four square sleepers. The gap between the sleepers is firmly encased by a cast iron that has been formed once. The finished waterwheel was hoisted on a crane.

Yao Ran stood in the water digging mud and sand, and there were four huge rectangular stones on the bank of the river not far behind him. On the upward side, there are two more holes on the two sides that are the thickness of an adult's waist.

After inserting eight pieces of wood more than eight meters high that matched the hole into the hole, Yao Ran let everyone see an unexpected scene, that is, these four huge cement stones were put by Yao Ran on a wooden plaque tied together with dozens of logs, and then floated on the water, how did such a heavy stone float on the water. In the amazed eyes of everyone. The four cement piers were put into the four pits dug by Yao Ran.

All the work was done under Yao Ran's personal guidance, and the waterwheel was fixed to eight wooden pillars. The huge flow of water hits the huge tiles on the edges of the wooden wheels of the waterwheel, and the tiles on each section of the wooden wheels are not arranged side by side. The advantage of this is that every minute and second, there will be an impact force to drive the entire waterwheel to rotate non-stop.

After the installation of the waterwheel, all that remains is to drive the blower to rotate, no matter how fast the speed of the waterwheel is, it will not reach the speed of the impeller of the blower, so it needs a variable speed gear, this gear is competent by Yao Ran's cast iron, a large gear rotates and then drives a small gear. The pinion is the transmission wheel on the blower impeller.

After a simple shelf is built, a rope with 9 strands of rope wrapped together is as thick as a calf. After the central shaft of the waterwheel is fixed, the other end is fixed on the big gear of the blower test bench and the big gear and the pinion are fixed with a clay fired frame, and the rotating waterwheel drives the rope, and the rope transmits the rotating power to the impeller of the blower one by one, and the pinion begins to rotate at high speed under the drive of the big gear. The force of the waterwheel to rotate, not to mention driving such a gear, ten is no problem. Pulling five apprentices, standing in front of the blower, feeling the sound of the wind from the temporarily installed blower, and the blades slapping on the air, and then coherently.

Yao Ran opened his hands and said, "Come on! to feel the power of knowledge. A few apprentices followed Yao Ran's example, Xiao Mumu glared at his eyes and muttered, "Isn't this the wind?" ”

Yao Ran looked down at Xiao Mumu and said, "That's right, this is the wind." Then he straightened up again and said, "But I can let the wind blow wherever I want, wherever I want." ”

Xiao Mumu tilted his head and thought, I want the wind to blow anywhere, are there some places where there is no wind? This is Yao Huo bowing his head and whispering in Xiao Mumu's ear, "Is there wind in your house?" Can you let the wind blow in your room? A little wood is a little wood. ”

Xiao Mumu straightened his head, and then a realized expression emerged, "Oh~~ That's it, I understand!" Then his expression changed to very annoyed and said, "My name is Xiao Mumu, not Xiao Mutou!" ”

Watching them playing, Yao Ran was very pleased to glance at Yao Huo, this kid will definitely become a generation of educators in the future, looking at the rotation of the waterwheel, Yao Ran ushered in a large number of new forces, because the houses in Yao Village have all been completed.

Yao Ran hasn't been back to Yao Zhai to see these days, but since everyone said that it was done, Yao Ran opened the retina system to take a look at the general situation, although there were some small differences in the distance between the houses, but there was no problem in general. The drainage system is pre-designed by yourself, and there are roads that crisscross and cross the country. Now that we have the technology and experience to burn air supply pipes, it should not be a problem to fire a sewage pipe.

There is also drinking water and domestic water, which can be fired from the raw materials of refractory bricks, although there may be water seepage, but it is different from modern society, and it is not a high-rise building densely populated. As long as there is a water inlet in the yard of each house, the water outlet will follow the sewage outlet at the same time.

Originally, I wanted to make a biogas digester for fire, but now with a blast furnace, there will naturally be gas. The digester is less important, but the work can still be carried out, and the work can be left to the students, after all, the taste is not very good. At the same time, it can also be turned into a practical assignment.

After the inspection was satisfied, Yao Ran arranged for Lang Mao to lead everyone to help Yao Bone complete the construction of the academy, and he left a large number of clansmen surnamed Lin on his side to start building houses and burning charcoal.

The work of burning charcoal has declined a little as the number of trees on the other side of the river has declined, but at present there are nearly 2 tons of charcoal in reserve, which we may not think is a lot now, and for so long, only 2 tons in almost ten days is indeed very small, but that is also because of the lack of manpower, the number of each fire is small, and occasionally there is a leak of wood in the main hole is all burned into ashes.

Therefore, Yao Ran is not worried about the ore collection situation and quantity on Weimu's side, but his side is indeed overstretched. Now this group of new forces is of course to burn a large amount of charcoal, and the retina system reminds that because of material reasons, the fuel ratio of the blast furnace built by itself is expected to be as high as three to one. What is the concept, that is, 3 tons of charcoal plus 1 ton of iron ore, and then the production rate of siderite with 40% iron content excludes 5% of the waste residue, that is to say, 3 tons of charcoal can produce 350 kilograms of pig iron, that is, there are 700 catties of pig iron.

Although this figure was already a very high standard in ancient times, the amount of charcoal consumed in this process was really enough for Yao Ran to drink a pot. 3 tons of charcoal, according to the previous speed, 3 tons of charcoal will take at least 15 days to produce, during which it will be even more difficult to say if it rains or other weather. So what is needed now is more charcoal production.

This is still thanks to the blessing of the system, if it were not for the credit of the retina system, Yao Ran really didn't know this ratio, and he didn't know how many furnace ores he had to practice to make iron. The next step is to need a stone crushing device.

Because if you want to make iron, you must smash the iron ore, so there must be a machine that can quickly smash the iron ore, Yao Ran chose this way, because it is relatively simple to make a cast iron mill, and there is a ready-made water wheel, which is nothing more than hanging an extra rope.
