Datang Industrial Zone is a separate courtyard surrounded by five hundred guards in full body armor. This courtyard covers an area of about 1,000 acres and contains various factories and equipment.
There is a plaque hanging at its door, Datang Academy of Science and Engineering.
The plaque was written by Li Ke. Unfortunately, little Jinyang is still too young. When little Jinyang grows up, let her imitate Old Li's handwriting and use Feibai's handwriting. It is said that the fake can be mistaken for the real.
The courtyard wall here is two meters high and no one is allowed to visit casually. Of course, there are guards protecting the outside of the entire industrial zone, and there are separate guards inside.
At present, there are a total of 1,372 craftsmen working here for a long time. A considerable number of these craftsmen were poached from various households after Li Ke increased their monthly salary, and gradually came to Li Ke.
And all the craftsmen on the periphery are proud to be able to enter here.
It can be said that those who work here are really craftsmen. There are no apprentices, and those who do the work are real craftsmen. In addition, there are a group of people specially trained in each factory, who are trained according to the standards of later generations. What kind of eighth-level fitter method is used to train a group of people.
As for why these people are trained, the reason is very simple. Before the industry reaches a certain level, the precision of human hands is actually much higher than that of machinery. Even after more than a thousand years later, in 2020, in many industries, machines will not be able to I dare say that my accuracy can 100% exceed that of manual work.
Therefore, these people are naturally trained to prepare for the first batch of industrial mother machines in the future.
The purpose of the craftsmen here in the Engineering Academy is much simpler, mainly research and development and improvement.
When Li Ke arrived, the craftsmen headed by Lu Daqiang and Liu Chang were already waiting in line here.
"Your Highness."
"Your Highness." His Highness's voice was full of fanaticism. These craftsmen knew even more clearly that compared to His Highness, they were nothing.
"How's it going? Tell us about your achievements? Let's start with Liu Chang." Li Ke asked with a smile.
Liu Chang mainly made the Quyuan Li before. The Quyuan Li could not have been developed by Liu Chang. Liu Chang himself understood this very well, but His Highness needed him to stand up and bear this honor. Liu Chang also knew very well that he was His Highness. He is an example to the world, so Liu Chang has always been very attentive, and he wants to make his efforts worthy of the trust given by His Highness.
Of course, what cannot be ignored is that Liu Chang is a real master in the carpentry industry. In fact, like Lu Daqiang, both of them are considered masters in the carpentry industry.
In ancient times, there were many masters from all walks of life, but the truly awesome masters were almost always in the field of carpenters. Perhaps because carpentry was used in almost all fields in ancient times, there were the most truly awesome carpenters.
"Your Highness, the seeder you gave us has been successfully developed." Liu Changxian reported his first achievement.
"Oh? Go take a look." Li Ke immediately looked curious. The library he got contained a large number of basic farm tools, but most of the basic farm tools were made of pig iron or even steel. Don doesn't apply.
The external environment of the Tang Dynasty is not stable, so steel must be the first to make weapons. There is no doubt about this. Even Li Ke cannot change this now, and parts can be cast with a large amount of wood and a small amount of pig iron. Farm tools are the most fundamental.
The seeder is one of them. The seeder is not mysterious or high-end. In fact, as early as the Han Dynasty, the early prototype of the seeder was already born. Even more than a thousand years later, in the 1970s and 1980s, northern China The seeders used in major farming areas with relatively large amounts of farmland are not much more advanced in principle than the columbines of the Han Dynasty.
It's just that some improvements have been made in terms of transmission devices and materials.
Liu Chang took Li Ke to this improved seeder. When Li Ke saw it, the appearance alone evoked memories of his childhood. The seeder Li Ke used when he was a child was very similar to this thing.
Li Ke remembered that the seeder he had when he was a child in his previous life was not big. It was wider than a mule and had five legs. The wheels on both sides of the seeder were made of iron and driven by chains. Then there was a rectangular square bucket on top, with an inverted bucket inside. The diamine used as base fertilizer is mixed with wheat seeds, and then poured together into a square bucket for sowing.
The five holes at the bottom of the square bucket correspond to the five hollow sowing legs, and in the middle of these five holes are grooved threads similar to waterwheels, which can be twitched laterally. The grooves inside are of different sizes, and the size of the grooves is used. To adjust the number of seeds sown by rolling the wheel once.
There is no such groove thread on the bottom of the columbine bucket of the Tang Dynasty. In this case, there are no rollers on both sides of the columbator. In this case, it is easy to cause the amount of wheat to be too much or too little at one time and not so uniform. In fact, most of the time it is less.
In his previous life, Li Ke's grandfather told him that when they were young, the seeder was called a columbine, and they had to shake it when sowing. Because if they didn't shake it, the seeds would often get stuck together. After all, the hole couldn't be too big.
Moreover, there are no wheels on both sides of the columbine, which also consumes a lot of animal power. The improved iron ones that Li Ke had seen when he was a child were also called iron cogonquins by his grandfather and others. You can imagine how many years this name has been used.
The seeder that Liu Chang and his team have modified is now very close to the seeder that Li Ke used when he was a child.
"Your Highness, we have conducted several tests on this seeder. First of all, the wheels on both sides of it are made of die-forged pig iron wheels, and then the bearings in the middle of the wheels are equipped with such seeding grooves. The grooves are also made of iron. , we fixed the size of the groove.”
"We have tested what Your Highness said, that the middle groove bearing can twitch left and right to change the size of the groove, but it is a bit complicated, very difficult for our production process, and the failure rate is very high. So we made it fixed so that it doesn’t need to be replaced, and its structure is much simpler. As for controlling the number of seeds, we chose to place a piece of wood at the entrance of the seed bucket to adjust the size of the seed entrance. To adjust the number of seeds for different crops such as wheat." Liu Chang introduced.
Li Ke nodded with satisfaction. The plan he provided to them may be very advanced, but to be advanced, you must consider the actual situation. Liu Chang and the others did a very good job. This method of narrowing the seed entrance and exit is very good and reduces the overall cost. Planter production difficulty and failure rate.
Although this method of jamming the wood chip baffle is because the seed opening will be buried at the bottom by a large number of seeds when sowing, sometimes the wood chips are not stuck properly and will close by themselves and other minor defects.
But this small flaw is not a big problem, because there will be people following behind the seeder, and a section in the middle of the five sowing legs will be empty. There is probably a part of the space from the top to the bottom, just to allow people behind to observe. Did any seeds fall?
It’s not that it’s not integrated, but it’s that a section of it is intentionally left empty.
