The principle of the flower machine is very simple, and it didn't take much effort to make it under the hands of the bandstage. Pen, fun, pavilion www. biquge。 info But because there are some small flaws, so the orchestra station has been re-improved, and it has been made.

The efficiency of the wooden box type is nearly 20 times higher than that of the bowstring type, and in terms of the flower machine, Datang can be said to be in place in one step. In later generations, the wooden box type elastic machine was invented in Japan, introduced into China at the end of the Qing Dynasty, and almost all of them were based on it after the liberation of New China. It was not until later that the large bouncy machine replaced the wooden box bouncy machine. However, it is still used in a few remote and poor areas.

And the machinery required for a large flower machine, even if it can make a flower machine, it can't make a power device that can drive it, so it can be said that the flower machine is almost like this.

Li Shimin was anxious to see the effect of cotton, and Letai worked two days overtime to make the improved finished product. Wooden wheels are additionally added underneath for easy movement. There is also a buckle on the wooden wheel, and the buckle is buckled down when it is used in the interior on weekdays, which can just buckle the wooden wheel, and it is more stable to park and will not run around.

Xia Hongsheng took out some cotton and tried it, one person can operate, knowing that the cotton is poured on the incoming board, and then go to the side to turn the big gear, as the incoming board enters the wooden box, the cotton on it is quickly bounced many times in the wooden box by a number of horizontal and vertical strings, and then with the incoming board from the other side of the wooden box, it is already played cotton. In the past, the bowstring flower tool only had one string, and it could only be used at the point where the bowstring touched, and the small strength could not be bounced, and the cotton wool was bounced up when the strength was large, and it was everywhere, easy to inhale into the lungs, and cause lesions in the long run. After the cotton enters the wooden box, those strings are laid on the cotton, and the strings are bounced with the rotation of the gears, so that those are quickly bounced up with a certain strength, and a whole piece of cotton is bounced at once, and because the strings are spread on the cotton, the cotton after ejection is very uniform. And because it's in a wooden box, those tiny cotton wool won't run around.

Although the bouncy machine was made, the cotton that was bounced out during the test of the bouncy machine was also handed over to the people on the Zhuangzi to spin and weave cloth, and when the time came to make the cloth, Li Shimin would see the difference between cotton cloth and linen.

And Li Shimin was anxious to see the cold effect of cotton, Xia Hongsheng had some considerations.

Because it is not only necessary to look at the finished cotton clothes, Xia Hongsheng wants Li Shimin to see the whole process, from the original state of the cotton, to the cotton playing, to the appearance after playing, and then to the whole process of filling the clothes as a filler to make a cotton jacket.

Whether to take the cotton machine to Chang'an and take it to the palace to demonstrate it to Li Shimin, or to send Li Shimin to Jingyang and let him go to the academy to see it himself. This is a question that Xia Hongsheng considers.

He certainly hoped for the latter.

Today, these more than 200 students have verified the teaching system of the college, and the way of life and learning of the college has been experimented with by these students, and it can be pushed forward even more widely. If it can be successful, the next step is to expand enrollment and carry it forward, if not, then because of the small number of students, so there is not much trouble. Now a year has passed, and it has been proved that the academy can be in full swing.

Since the academy wants to be in full swing, it must enroll students on a large scale. Admissions are going to be promoted, and there is no better propaganda advertisement than the emperor.

After thinking about it for a long time, Xia Hongsheng decided to try it and see if he could let Li Shimin personally visit Jingyang Academy. If he didn't agree, then he had to pull the flower machine to Chang'an.

Because there was no class in the evening, Xia Hongsheng returned home from the academy and was going to sit in the study for a while, first, to think of an excuse to persuade Li Shimin to come to the academy in person, and second, to sort out the methods of training naval soldiers and naval landing personnel.

As soon as the clinker arrived at the entrance of the study, he saw Youji coming out of it, holding a stack of handpaper from Xia Hongsheng in her hand, and she happened to bump into it.

Xia Hongsheng smiled helplessly: "You come to get my notes again!" ”

"Hee-hee, there are a lot of novelties in Childe's Codex!" You Ji shook the pile of paper in her hand and said, "The concubine is really curious, what is the steam engine?" There is actually the power to push 10,000 catties? And the internal combustion engine...... It's the first time I've seen such a word for the alternating current and direct current, as well as the saying of the law of the jungle and the idea of survival of the fittest, and the concubine is quite touched after reading it......"

Uh, the things on those codexes are all when Xia Hongsheng is idle and bored, sometimes he writes down some things that he suddenly remembers, one for later use, I am afraid that I will suddenly not remember it when I really use it, after all, the knowledge brought by the crossing is very scattered, if you don't start recording it from the bits and pieces, sooner or later you will have to forget it, the so-called good memory is not as good as a bad pen. Second, it is also a joke for future generations, just like Leonardo da Vinci's manuscript, in which the advanced scientific inventions and ideas are simply amazing, and I feel that Leonardo da Vinci must have traveled back. In fact, Xia Hongsheng now feels that he must have traveled back!

Leonardo da Vinci's manuscripts are mysterious, all-encompassing, including robots, helicopters, flying machines, machine guns, armed tanks, munitions, military parachutes, diving suits made of pigskins with breathing hoses, and so on. Even the infinitely continuous automatic transmission, the submarine, the gear device that was interpreted as the first mechanical computer, and the world's first programmable mobile robot. In addition, during his years in Vatican, da Vinci planned to use solar energy......

In the past, Xia Hongsheng felt magical and mysterious, but now Xia Hongsheng feels that Da Vinci must be a time-traveler like himself, and those manuscripts are all to prevent him from forgetting for too long in that backward space-time zone, so once he suddenly remembers something, he quickly writes it down regardless of whether it is useful or not, and then talks about it, in case it can be used in the future? Moreover, in order to prevent others from stealing, Leonardo da Vinci's manuscripts were all written in mirror text, which made it more difficult for the reader to read.

Maybe these things will be passed on, and there will be a Xia Hongsheng manuscript that countless people feel magical and mysterious in the future, hehehehe...... (To be continued.) )
