Datang: Li Shimin begged me to rebel

Datang Industrial Zone, a separate courtyard surrounded by 1000 full-body bright armor guards, this courtyard covers an area of ​​about [-] acres, and there are various factories and equipment inside.

At its gate hangs a plaque, Datang Academy of Science and Engineering.

The plaque was written by Li Ke, but it's a pity that Xiao Jinyang is still too young. When Xiao Jinyang grows up, let her imitate Lao Li's handwriting and use Feibai handwriting. It is said that the fake can be confused with the real one.

The courtyard wall here is two meters high, and it is strictly forbidden for anyone to visit casually. Of course, there are guards protecting the periphery of the entire industrial area, and there is even a separate guard inside.

At present, there are a total of 370 craftsmen working here for a long time. A considerable part of these craftsmen were recruited from various households after Li Ke raised the monthly salary, and gradually turned 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 start work are real craftsmen. What is the way to train a group of eight-level fitters.

As for why these people are trained, the reason is very simple. Before the industry reaches a certain level, the precision of human handwork is actually much higher than that of machinery. Even after more than 1000 years and 2020, in many industries, machines dare not say My own accuracy can be 100% higher than artificial.

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 Academy of Engineering 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 was full of fanaticism, and these craftsmen knew better than His Highness that they were nothing.

"How is it? Tell me about your achievements? Start with Liu Chang." Li Ke asked with a smile.

Before Liu Chang, he mainly made Quyuanli. Quyuanli could not have been developed by Liu Chang. Liu Chang himself knew this very well, but His Highness needed him to stand up to bear this honor. Liu Chang also knew very well that he was His Highness. Liu Chang has always been a role model for the world, so Liu Chang has always been hardworking, 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 true master of the carpentry industry. In fact, like Lu Daqiang, both of them can be regarded as masters of the carpentry industry.

There were many masters in all walks of life in ancient times, but the truly awesome masters were almost all in the field of carpenters.It may be because carpentry was used in almost all fields in ancient times, so there are the most master carpenters who are truly awesome.

"Your Highness, the planter you gave us has been successfully developed." Liu Chang first reported his first achievement.

"Oh? Go take a look." Li Ke immediately looked curious. There were a lot of basic farm tools in the library he got, but most of the basic farm tools were made of pig iron or even steel. Don does not apply.

The external environment of Datang is not stable, so steel must be the first to make weapons. There is no doubt about this. Even Li Ke can't change these now, and some parts can be cast by a large amount of wood and a small amount of pig iron. The farm tools are the most fundamental.

The seeder is one of them. The seeder is neither mysterious nor high-end. In fact, as early as the Han Dynasty, the early prototype of the seeder was born. Even in the 1000s and 80s after more than [-] years, the amount of farmland in the north The seeders used in the relatively large main cultivated areas are not advanced in principle compared to the columbine carts of the Han Dynasty.

It's just that some improvements have been made in terms of transmission and materials.

Liu Chang brought Li Ke to this improved planter. When Li Ke saw it, the shape alone aroused his childhood memories. The planter Li Ke used when he was a child was very similar to this one.

Li Ke remembers that the planter he used in his previous life was not big when he was a child, just wider than a mule and had five legs. The wheels on both sides of the planter were made of iron and driven by chains. The diamine that goes in as the base fertilizer is mixed with wheat seeds, and then poured into the square bucket together for sowing.

The five holes below the square bucket correspond to five hollow sowing legs, and there are groove threads in the middle of these five holes similar to the waterwheel, which can be moved horizontally. To adjust the number of seeds sown by rolling the roller once.

Datang’s columbine cart does not have this groove thread under the square bucket. In this case, there are no rollers on both sides of the columbine cart. In this case, it is easy to cause too much or too little wheat at a time, which is not so uniform. In fact, most of the time it is too small.

In the previous life, Li Ke's grandfather told him that when they were young, the planter was called a columbine cart, and they had to shake the columbine when planting, because if they didn't shake it, the seeds would get stuck together in many cases. After all, the hole should not be too big.

Moreover, there are no wheels on both sides of the columbine cart, which consumes a lot of animal power.The improved iron ones that Li Ke saw when he was a child were also called iron columbine by his grandfather. One can imagine how many years this name has been used.

At present, the planter that Liu Chang and the others have transformed is very close to the planter that Li Ke used when he was a child.

"Your Highness, we have conducted several tests on this planter. First of all, the wheels on both sides of it, we still use cast iron wheels forged by dies, and then the bearings in the middle of the wheels are equipped with such seeding grooves, which are also made of iron. Yes, we have fixed the size of the groove."

"We have tested what your highness said, the way that the groove bearing in the middle can twitch left and right to change the size of the groove, but it is a bit complicated and very difficult for our production process, and the failure rate is high. So we made it fixed, so that it does not need to be replaced, and its structure is much simpler. As for regulating the amount of seeds, we choose to set a wooden piece at the entrance of the seed hopper to adjust the size of the seed entrance. To adjust the number of seeds of different crops such as wheat." Liu Chang introduced.

Li Ke nodded in satisfaction. The plan he provided to them may be very advanced, but the actual situation must be considered in advance. Liu Chang and the others did a very good job. This way of reducing the seed entrance and exit is very good, reducing the overall The production difficulty and failure rate of the planter.

Although this method of locking the wood chip baffle, because the seed opening will be buried at the bottom by a large number of seeds when sowing, sometimes the wood chip is not stuck properly, and it will close by itself and other small defects.

But this small flaw is not a big problem, because the seeder will be followed by people, and there will be a section of the five sowing legs that is empty, and there is probably a part of the space from the top to the bottom, just for the people behind to observe. Did any seeds fall.

It's not that it can't be integrated, but it's intentionally left blank.
