Chapter 59

Rolling bearings are generally used for rotating parts, which can greatly reduce the friction of rotation.

If the rolling bearing is applied to the cattle powered rollover, it can naturally save a lot of effort for the cattle. In this way, the hydraulic rollover that originally needed to be pulled by four cattle only needed two cattle.

The invention of rolling bearing in his time needs to be traced back to the 17th century. The most important part of rolling bearing is steel ball, and the outer ring of bearing is relatively simple.

But even so, Xiao Ming can't let craftsmen produce high-precision rolling bearings now. His method of manufacturing steel balls is to use the lowest free falling motion.

This method is to let the molten steel fall freely. In the process of falling, the molten steel and water will naturally form a ball. Under the molten steel is the cooling water, and the molten steel will fall into it and quickly cool into a steel ball.

The steel balls produced by this method are of different sizes and different surfaces. The next step is the processing of grinding machine, which tries to grind the steel balls into spheres of the same size.

Now Xiao Ming applies this kind of bearing to niuli dumper, in order to make the dumper have an irreplaceable accessory, so that no one can copy it at will.

Because he's also going to sell it to the businessmen who run the mines.

In this era, the water in the mine is the most troublesome problem for miners, and the hydraulic dumper can not only irrigate the farmland, but also pump water from the mine.

As Pang Yukun issued a decree to send skilled craftsmen to Qingzhou to study, the news of Niu Li's rollover gradually spread.

A businessman who has always been shrewd will not ignore this news. In fact, it is because of what Xiao Ming instigated one after another.

Now businessmen are very concerned about any changes in Qingzhou and hope to seize business opportunities before others.

Of course, Xiao Ming didn't hide it, so he directly asked the equipment department to place Niu Li on the spot.

"Your Highness, this waterwheel is really good. It can pump as much water as the previous ten days."

The first to learn the news is naturally the local aristocracy in Qingzhou. Wang Shijie and others found the location of the water wheel only one day later.

Besides, the boy is very cunning and has a servant with him, but Xiao Ming only takes a look and knows that he must be the top carpenter of the Wang family.

Because just from then on, he could see the rough palm of his hand and the surprised look of the waterwheel.

"No, at least twelve days." Xiao Ming said confidently that although this kind of niuli dumper still uses niuli, its ability is basically equivalent to a modern small electric pump.

If the cattle are changed continuously, the amount of irrigation will be considerable.

Qin Mu has come back from Chang'an. This time, Wei Qing and sun Dong have also arrived. The four self appointed members are all here.

Since the influx of a large number of foreign businessmen in Qingzhou, the four of them are more attentive to Xiao Ming. Now they are just like followers all day long. If they have nothing to do, they just go to Xiao Ming.

"Twelve days!" Qin Mu exclaimed, looking hard at the overturned structure and recording it secretly.

Sun Dong and Wei Qing are the same. Xiao Ming squeezed a lot of money out of the four auctions of the chamber of Commerce.

Now they want to save as much as they can, and unlike soap, the rollover is clearly here.

Xiao Ming laughs and doesn't reveal it. He can't hide the rollover. Now he can only say that if other people can make it, he can only recognize it.

If it doesn't, it's profitable.

By using the patent department, he could control the territory of the fiefdom, and no one dared to imitate it, but he could not control other parts of Dayu.

The four of them took a look, chatted with Xiao Ming for a while, and went back to each other.

"Your Highness, these four people are stealing school." Green Luo says contemptuously.

Xiao Ming said with a faint smile: "Hey, if you steal learning, you can steal it. It's not certain whether you can succeed or not."

With that, he turned and looked at the land beside the Xiaoqing River. Lufei's winter conscription had ended. Five thousand recruits and three thousand remained in Qingzhou, and the others were assigned to other states and counties.

Because he got one million taels of silver, Lufei's heart was also big. He still didn't stop conscription in spring. He discussed with Lufei and planned to recruit another 5000 people to control the army of the fiefdom to 13000.

If there is enough food in Qingzhou next year, we will consider conscription.

Among the new recruits, Xiao Ming asked Lu Fei to select some fishermen's children from the coastal areas.

Navy building is not a matter of one day. It is just a matter of looking for directions in the sea.

In this era, the so-called navigation is basically that Shanghai ships go along the mainland, so that they will not lose their way. Xiao Ming selected these people to cultivate a generation of people who know how to navigate.

Now his plan is being implemented step by step according to the plan, such as the Construction Corps. Now, in his field, new recruits are pulling cattle to reclaim land, and hundreds of cattle are pulling plows.

In other uncultivated places in Qingzhou, Lu Fei also took the soldiers under his hands to reclaim the land.

In order to make the Construction Corps open up their fields quickly, Xiao Ming also provided the corps with the best farming tools this time. Not to mention the sufficient cattle, it was the first time that the cattle overturned.He hoped that the granary of the fiefdom would be filled in the coming year.

With Xiao Ming's eyes, lvluo said with a smile, "Your Highness, it's the first time I've seen a soldier in this area. "

Xiao Ming knocked on lvluo's head," with me, you see a lot of things for the first time? "

after walking around the cultivated land, Xiao Ming checked the reclamation, and then he and lvluo went to Qingzhou City.

At this time, there is still snow left on both sides of the official road to Qingzhou. The cold of winter has not faded, but spring is not far away. It will be a season full of hope.

Like his fiefdom, it is a place full of hope.

After two or three months of busyness, he churned out a lot of goods that Dayu didn't have. These goods are also expanding their influence and bringing him profits.

But the road ahead is unknown, and he dare not relax at all.

Born in the royal family, sometimes I can't help myself. If I don't go forward, there will be an abyss behind me.

After entering Qingzhou City, the flow of foreign merchants makes Xiao Ming smile. Now he has at least taken the first step. Next, he has to attract more merchants to buy land and build workshops in Qingzhou.

Then the goods produced from Qingzhou are continuously transported to all parts of Dayu, bringing huge profits.

In order to achieve this goal, he also needs to come up with more products to attract merchants.

perfume, soap and liquor are only the lowest in Xiao Ming's eyes. There is still a little technological content in the cattle rollover, and countless technology in the science and technology library is waiting for him to become a real commodity here.

But now Xiao Ming is aware of a problem, that is, his fiefdom is seriously short of technical talents, and Pang Yukun has set a very good precedent for the state and county to send craftsmen to study.

Now it's time to reserve technical talents and expand the scale of production. These technical talents will be born from slaves, because they are the most easily controlled people at present.
