- Chapter 633: [Cotton seed removal]
¡¡
Master Lu is still wearing the same clothes, a blue seventh-grade official's clothes.
Next to him, there was a wooden thing, like a barrel. As Master Lu shook his hand, the barrel inside seemed to be rotating.
It¡¯s just that it¡¯s far away and I don¡¯t know what¡¯s inside.
Hearing the footsteps outside, Master Lu turned his head, saw Li Chengqian and Duan Lun coming back, and saluted quickly.
Li Chengqian waved his hand.
The person Duan Lun mentioned who came up with the solution didn't tell him just now. Now that he sees Master Lu here, wouldn't it be Master Lu who came up with it?
He looked at Duan Lun, and Duan Lun said: "Your Highness, since you gave the order, you asked me to find the person who can remove the seeds. After learning about it, Carpenter Lu devoted himself to research, and finally came up with this method today. After After tests by Chen and Carpenter Lu, they were indeed able to separate cotton from cotton seeds!"
"Okay, Master Lu is really smart!" Li Chengqian praised, "I wonder how you did the seed removal?"
Master Lu said: "Your Highness, this was not accomplished by me alone. It was thanks to Brother Blacksmith Zhang that Lu was able to make this seed-removing bucket!"
While they were talking, a voice sounded outside: "Give in, give in!"
Hearing this, many people outside got out of the way.
Li Chengqian heard that the sound seemed to be coming this way. He turned around and saw two buckets moving this way. It was clear that someone was holding the buckets to come in.
He quickly got out of the way.
The person who came in was Blacksmith Zhang. After he put down the bucket, he saw Li Chengqian and saluted quickly.
After Li Chengqian responded, he asked: "These two barrels too?"
"Oh, Your Highness, are you talking about these seeding buckets? Yes, they are the same as the buckets that Brother Lu brought before. I was just afraid that one was not enough, so I made two more. At the speed of three buckets, I made them in half a day. You can take off the seeds from this pile of white piles!" Zhang Jiangjiang said.
Li Chengqian asked: "What is the principle of action? Tell me!"
With the explanation and demonstration by Master Lu and Blacksmith Zhang, Li Chengqian understood the principle of this seed-removing bucket.
This is a wooden barrel with a small cylindrical barrel that can rotate inside. The small barrel has serrations around the outside.
The large wooden barrel is divided into two sides, separated by wooden boards.
Put the seeded cotton on one side and leave the other side empty. The barrel on the side where the seeded cotton is placed has a side close to the small wooden barrel. I made a mesh iron piece.
When work begins. A person turns a small wooden barrel. While his feet are turning, his hand can pick up a handful of cotton and put it into the large wooden barrel. Then it is attached to the mesh-shaped iron sheet. At this time, the cotton peeking out of the mesh is bitten away by the saw teeth of the small wooden barrel. The mesh is smaller than the cotton seeds, so the cotton seeds cannot pass through. So when the cotton in my hand was almost bitten, only the seeds were left!
"After the small wooden barrel bit away the cotton here, the saw teeth of the empty wooden barrel suddenly retracted in. The cotton was blocked by the wooden barrel and fell outside the big wooden barrel.
This is strange, why does the small wooden barrel stretch out to bite the cotton when it is turned to this side, and then shrink in and spit out the cotton when it reaches the other side?
He took another unused barrel. Take a look inside.
Inside the small wooden barrel, there is actually a sawtooth iron cylinder. It is not coaxial with the small wooden barrel, but is close to the side of the mesh-shaped iron piece, so when it rotates. The saw teeth will extend out on the side close to the mesh, and will retract in on the other side.
Master Lu operated the seed-removing bucket alone, and soon produced a small handful of cotton without seeds.
Li Chengqian picked it up and looked at it, and sure enough, there were no seeds!
He praised: "Good. It's so smart!"
He looked at Duan Lun and said: "Give the rewards promised before to the two craftsmen! From now on, we will use this kind of deseeding bucket to deseed cotton!"
"Thank you, Your Highness, Prince!" Master Lu and Blacksmith Zhang said. Master Lu said at this time: "Your Highness, this seed-removing bucket still has many shortcomings. For example, this cotton can remove seeds, but it will leave a lot of cotton residue. There is no way to clean out all the seeds. I will study it more carefully in the future and study the seed removal barrel in more detail so that the seeds can be removed more cleanly!"
"Okay, you are worthy of a reward if you have this intention. I hope you can continue to work hard in the future and invent a better seed-removing bucket!" Li Chengqian said to them.
"The method of removing seeds has been found. The next step is to spin the cotton into thread, then make it into cloth, and then the cloth is made into clothes. Take a lookHow about the quality of the clothes? Once the clothes come out, Lao Li can promote cotton planting.
Li Chengqian didn¡¯t know the technology of cotton spinning.
But there was no need for him to worry. The Tang Dynasty already had mature technology in this area, and Duan Lun had people start work on it that day.
A few days later, Li Chengqian received the clothes from Duan Lun, and they were indeed made of cotton!
100% cotton!
Li Chengqian touched it and found it was indeed good.
Now that the clothes came out, Li Chengqian discussed it with Duan Lun, and then after being fully prepared, he took the clothes to see Lao Li.
Lao Li touched the clothes Li Chengqian sent and listened as Li Chengqian cooperated with Duan Lun below to introduce cotton's drought resistance and easy planting, the advantages of planting without occupying fertile land, and the quality advantages of cotton made into clothes. If cotton is promoted , will be able to solve the clothing problem of the people of Tang Dynasty in the future.
Food, clothing, housing and transportation, clothing and quilts are ranked first among people's needs, which shows the importance of clothing to people.
When Lao Li heard that his son had new fabric materials, he became very concerned about it.
Touching this piece of clothing, it turned out to be cotton that he would go to see twice a year. Before going to see it this year, he was told that it had been picked by Li Chengqian. He never expected that the cotton originally called Baidianzi could be made into such good quality. clothing.
When Li Chengqian and Duan Lun finished talking, Old Li chuckled and praised Li Chengqian and Duan Lun first. In his praise, he affirmed the value of Li Chengqian and Duan Lun's cotton clothes, and then said: "I will inform you immediately about the promotion of cotton cultivation. The ministers from the three provinces came to discuss and fully promote this matter, and Cheng Qian and Aiqing will carry out the matter!"
"Thank you, Father!"
"Thank you, Your Majesty!"
After the two saluted, they left Lao Li some space to discuss with the ministers!
Li Chengqian waited for two days, but did not see Duan Lun coming to see him about this matter, let alone telling him about the cotton promotion plan, which made Li Chengqian curious.
He didn¡¯t go to the Ministry of Works to find Duan Lun. Hasn¡¯t Master Lu been working on the seed-removing bucket in the Ministry of Works recently?
Although most of the cotton has been deseeded, a small amount of cotton is still left for Master Lu and his two colleagues to use for experiments. Just ask Master Lu for some information!
