The train driver in the courtyard

Chapter 491 The idea of ​​automatic umbrella, air suspension, Jia Dongxu got the banana
Early the next morning, we had breakfast.

Li Aiguo went to Wang Dakui and took fifty kilograms of bananas. He carried ten kilograms and took Chen Xueru with him on his bicycle to Chen's house.

My sister-in-law was about to give birth and had not been at work for a while. When she heard the noise, she immediately came out to greet her.

When she saw the banana, she was so shocked that she couldn't even close her mouth.

"Patriot, I seem to have seen it at the factory director's house. This, is this a banana?"

After getting the affirmative answer, the sister-in-law happily carried the banana into the house without paying any attention to Chen Fangxuan.

Chen Fangxuan turned his head and pretended not to see it, and Chen Xueru also looked a little embarrassed.

Normally, everyone should share this kind of rare thing. What's going on with my sister-in-law doing this?
The eldest brother said sheepishly: "She has a bad appetite these days. She vomits whatever she eats."

"It's okay. Pregnant women should take special care."

Li Aiguo laughed twice and put the matter away.

After hearing this, Chen Fangxuan's expression improved a lot. He stood up and asked Li Aiguo to sit down. He served tea and water, and also took out the snack box.

"Oh, I'm old and useless. I can't even open an umbrella."

During the Guangzhou Canton Fair, Li Aiguo and Yang Jizong had several sincere conversations about the development of Hex Technology.

It seems that automatic umbrellas have not appeared yet.

Pedestrians can only "put" the umbrella on their head and use it as a hat.

People need to have a sense of boundaries. Sometimes if other people's affairs are mixed in too much, it will cause resentment.

Chen Xueru didn't go home for a while, so she stayed at the Chen family to chat with Chen Fangxuan.

Looking at his infatuated father-in-law, Li Aiguo could only smile and say: "I didn't see it."

Before I even stepped out of the yard, it started to drizzle in the sky.

The two were chatting in the main room.

The sister-in-law was caught and revealed, with a trace of panic on her face.

The mistress turned back to the house, found an oil umbrella, and wanted to open it for Li Aiguo.

"Patriot, isn't this Canton Fair very lively?"

Looking at the mistress who felt sorry for herself, Li Aiguo smiled and asked, "Why don't you buy an automatic umbrella?"

However, the umbrella cover of the oil umbrella was too big, and since it had not been used for many years, the wife couldn’t hold it up even after holding it up several times.

"What is an automatic umbrella?" The teacher's wife handed the umbrella over.

Upright officials can hardly break housework.

"Xing Jia, my father and I are not separated. Your family already has a share of these bananas. Send this to my mother's family. My mother has never eaten bananas."

After a while, while Chen Xueru went to the shop to help, Chen Fangxuan asked in a low voice: "Aiguo, I heard that there were many people from Hong Kong at the Canton Fair. Have you seen Tailor Zhang?"

Li Aiguo took it and opened the umbrella with a lot of effort. He said smoothly: "It's the kind with a pressing place on it. Just press it lightly."

As a son-in-law, Li Aiguo can take care of some things and some things he cannot.

The two reached an agreement, which was to rely on Hex Technology to grab money from foreigners.

Some umbrellas are old, and the old-fashioned umbrella ribs cannot be held up due to lack of support, but they are reluctant to throw them away.

The fact that automatic umbrellas have become popular all over the world in later generations is enough to illustrate its product power.

"Patriot, come here, bring an umbrella."

After Tailor Zhang "disappeared", Chen Fangxuan initially thought that she had gone to a distant relative's home. He tried to inquire about her in many ways, but could not find her.

At this time, the rain was getting heavier and heavier, and the rainwater hit people's umbrellas, making a soft splashing sound.

If automatic umbrellas are designed and produced, there will definitely be a "money" future.

"It's not bad. More than 2,000 people participated. Our railway delegation sold more than 100,000 packs of instant noodles."

Seeing my sister-in-law busy stuffing bananas into the canvas bag, and then looking at the few large bananas, only half of them were left, my elder brother's face suddenly turned ugly.

I think I might have gone to Hong Kong City.

After the words came out of his mouth, Li Aiguo realized that he had been confused.

When they arrived at Liu Guozhang's house, Liu Guozhang had not returned from the research institute. Li Aiguo sat with his wife for a while, put down the bananas, and prepared to leave.

Even as a daughter, Chen Xueru felt a bit offended. She had never been treated so well when she returned to her parents' home alone.

After hearing what his sister-in-law said, the elder brother disapproved in his heart, but looking at his sister-in-law's big belly, his brain spoke well and he agreed with his mouth.

He closed the door and said with a straight face: "Daughter-in-law, this is what Patriot brought to our father. What are you doing?"

After Li Aiguo had dinner at Chen's house, he thought he would go to visit Liu Guozhang, so he left in advance.

Li Aiguo narrowed his eyes slightly when he saw this scene.

At noon, the eldest brother was preparing to cook and knocked on the door of his eldest sister-in-law, asking her to help.

Chen Fangxuan has never left the capital since he moved to the capital. Now he especially likes to listen to Li Aiguo talk about novel things outside.

On the way back, Li Aiguo rode his bicycle through the streets of Beijing, holding the cold bicycle handlebars in one hand and holding an umbrella in the other.

At this time, a gust of wind blew, causing the corners of the pedestrian's clothes to flutter, and blowing the pedestrian's hair wildly.

Those pedestrians were staggered by the wind, but they still tried their best to hold umbrellas and continued to move forward in the wind and rain.

Li Aiguo withdrew his gaze and made up his mind to rely on his own ability to design and manufacture an automatic umbrella.

He started the system secretly.

Open the system panel.

Steam engine driving: 100;

Cooking: 15;

Cycling: 95;

Geological exploration technology: 20;

EMU assembly body technology: 30;

Mechanical Skill Mastery: 60:

High-speed rail manufacturing technology: 0;
The current score is 313 points.

Search for automatic umbrella technology, and the system soon gave the answer.

The overall design of the automatic umbrella (need 100 points), the design of the umbrella handle (need 100 points), the ribs (need 100 points), the small umbrella cap, beads
These skills add up to at least 1000 points.

Li Aiguo looked at the pitiful 313 points and turned off the system without hesitation.

This dog system is a krypton gold system, trying every means to take money out of our pockets.

Furthermore, good steel is used on the blade.

Our goal, Li Aiguo, is to create an unpowered exoskeleton in preparation for rapid printing.

How can you spend points on these trivial inventions?

As a master of mechanical design, Li Aiguo decided to be self-reliant and rely on his own abilities to complete this design and manufacturing work.

The design principle of the automatic umbrella is very simple. At the hinge seat where the main rib and the support rib are connected, glue is injected into the groove of the U-shaped rib to form a pack of reset and hinge seats. The hinge seat is connected with the main rib. The ribs are formed in one piece, and one end of the ribs is riveted and fixed.
The most critical part is the umbrella spring.

The characteristics of the spring make the umbrella more mechanical, and the spring's elasticity, torsion, pressure, and tension rebound characteristics make the spring stronger and more practical.

In order to make a first-class automatic umbrella, it is necessary to use springs with first-class elasticity and strength.

The spring seems to be the key point of the unpowered skeleton, which is also the spring.

In other words, the spring technology used to make umbrellas may be the same as the spring technology used to make unpowered exoskeletons.

How about we have a chicken and two meals?
Prostitute the system once for free?
Thinking of this, Li Aiguo couldn't help but open the system.

The search keyword this time is spring.

Biu~
In an instant, a translucent blue screen appeared in front of Li Aiguo.

Various spring technologies are densely displayed on the screen.

There are everything from micro springs of a few millimeters in watches to one-meter-long leaf springs on engineering machinery.

Li Aiguo couldn't help but get excited and continued to search for spring technology related to unpowered bones.

What was presented to Li Aiguo this time were three types of springs, air springs, shape memory alloys, and elastic soft materials.

Among them, shape memory alloys and elastic soft materials are far beyond the material technology level of this era. Even if the technology is obtained, there is no way to produce them.

Li Aiguo spent 100 points to redeem air spring technology.

Countless pieces of knowledge turned into bits and pieces and sank into my mind. With the help of the system, those complex and obscure knowledge instantly became simple and easy to understand.

There was no discomfort during the entire process.

[Air spring is a type of fluid spring. It is a spring filled with compressed air in a retractable sealed container and uses the elastic effect of air.

Air springs have ideal nonlinear elastic characteristics. 】This looks like the air suspension used on luxury cars, right?

Air springs look awesome, but they are actually very common in life.

Dali pills are sold on the street, and the chest-breaking boulder often performed is a type of air spring.

Human beings are made of flesh and blood, how can they withstand the fierce blow of the hammer.

People who perform chest-breaking performances are just poor people who travel around the world. They are so-called poor in culture and rich in martial arts. It is impossible for them to learn advanced kung fu.

The reason why it can do things that even martial arts masters cannot do is because it uses the principle of air springs.

The hammer hits the stone slab quickly, that is, within a short impact time, the air in the chest cavity has no time to be discharged from the mouth and nose, forming an "air spring".

It is precisely because of the dynamic stiffness of the "air spring" that the body is protected from being crushed by impact.

Well, maybe the air suspension of luxury cars was inspired by the broken stones on the chests of ancient people.

Air springs are durable and suitable for use as umbrella springs.

After Li Aiguo figured it out, he rode his bicycle back to the courtyard.

Ahem, let’s go back and play TieTie with Miss Chen first, and then we can officially start the development plan tomorrow.

the other side.

Today is Jia Dongxu's happiest day this year.

He won.

Big win, special win.

In the morning, the steel rolling mill released wages. Jia Dongxu took the money and went to the woods by the river. After two hours of hard work, he won a total of 12 cents and three bananas.

The three bananas were used by a guy in a general's uniform who ran out of money to pay off his bills.

At the beginning, Jia Dongxu was reluctant. After all, the general owed him a full two yuan.

But the general said that these bananas were a southern fruit and could not be bought in the capital, so he still brought them out from home with great difficulty.

High-end fruit!
Jia Dongxu hadn't tasted the banana yet, and since it was the money he won, it was like picking it up. Even if it was wasted, he didn't feel bad, so he accepted the banana.

Holding three bananas, Jia Dongxu walked around the street for two hours, intoxicated by the envious looks of passers-by.

Seeing black spots on the skin of the banana, I was afraid that the banana would pus, so I turned around and walked towards the courtyard.

When he walked to the door, Jia Dongxu saw the third uncle carrying a tin bucket and preparing to pour vegetables.

Holding the banana high, Jia Dongxu looked like a child who scored double hundred points.

"Hey, hey, do you know the third uncle?"

The third uncle was startled, and the tin bucket fell to the ground. He was so distressed that he quickly picked it up and was relieved when he saw that there was no bump.

"Why are you so surprised, kid?"

The third uncle raised his head and was about to teach Jia Dongxu a lesson. When he saw the yellow-orange bananas, he looked surprised and said, "Is this a banana?"

"As expected of a man of culture, he even knows about high-end fruits." Jia Dongxu said proudly: "This is a fruit that only factory leaders can enjoy. Do you know how much this one costs?"

"How much?" The third uncle rubbed his hands cooperatively.

"2 yuan!" Jia Dongxu raised his head and put his hands on his waist.

Seeing his triumphant look, the third uncle suddenly lost his temper to talk, picked up the metal bucket, turned around and left.

"Hey, why are you leaving?" Jia Dongxu was confused.

This flattering person is too unprofessional.

The third uncle turned around and rolled his eyes.

"If I borrow a banana from you, will you give it to me?"

"That's not possible. How can I bear to part with such a precious fruit!" Jia Dongxu quickly held the banana in his arms.

"That's alright. Since you won't give it to me, why should I stay here?"

Look, our third uncle lives so clearly.

Looking at the back of the third uncle, Jia Dongxu spat.

The third uncle also wants to borrow things from their Jia family? Jia Dongxu felt that the third uncle was wishful thinking.

At this time, a resident passed by outside.

Jia Dongxu raised the banana, blocked his way, and asked, "Old Wang, do you know what this is?"

****
"It's time to make a living. My son is going to have a good time."

"I have known for a long time that my son is a person who does big things. Qin Huairu, look at this, this is a banana, a high-end fruit that only big leaders can afford."

Inside Jia's house.

When Jia Zhang saw Jia Dongxu bringing back bananas, she was so excited that she jumped and shouted.

At this time, because Jia Dongxu only brought back ten yuan a month, Qin Huairu looked down on him even though she didn't say anything.

Jia Zhang saw everything, but couldn't blame Qin Huairu. After all, Jia Dongxu was indeed outrageous.

There are old and young members of the family, but instead of supporting the family, they are just messing around all day, and they don't look like a man in charge of the family.

Now that she has encountered this opportunity, Jia Zhang naturally wants to reset her mother-in-law's profile.

Qin Huairu didn't expect that Jia Dongxu bought bananas, and his eyes lit up when he looked at the golden bananas.

"Dongxu, how much does this banana cost per pound?"

"One pound? Bananas are sold by the gram, one gram."

Jia Dongxu didn't know the price either, so he said nonsensically: "This banana costs 2 yuan."

"You can earn a living with 2 yuan, and Dongxu can earn a living." Qin Huairu looked at the bananas with greedy eyes, pursed her lips and said, "There are three bananas in total. There are exactly three adults and one child in our family. Each of us will share one banana. Just eat one with Banggeng.”

Jia Dongxu shook his head: "Daughter-in-law, I still have to stay with the uncle. They have lent us a lot of money these days. If the uncle knows that we are eating alone, he will definitely be angry."

"That old guy won't be afraid of losing his teeth even if he eats such a precious fruit." Mrs. Jia Zhang cursed angrily, but didn't stop her.

After all, now in the compound, his family still has to rely on Yi Zhonghai.

"Who lost his tooth?"

When Yi Zhonghai came back from get off work and walked to the middle courtyard, he heard yelling and cursing coming from Jia's house and walked over with his hands behind his back.

Mrs. Jia and Zhang did not lie to him, and stiffened her neck and said: "Master, whoever eats the big cake and doesn't give it to me will lose his teeth."

The deaf old lady has been in poor health since she was released and has no appetite for food.

A few days ago, Yi Zhonghai got two kilograms of fine white flour from the pigeon market and asked his aunt to bake brown pancakes.

Jia Zhang went to the door of Yi's house seven or eight times, but Yi Zhonghai didn't let her try it, so she remembered it in her heart from then on.

"Sister-in-law, that's for the old lady. You also know that the old lady was punished by Li Aiguo and almost lost her life.

Only with the help of the deaf old lady can we live a better life in the courtyard. You need to take a longer view. "

Yi Zhonghai looked at the angry Jia Zhang and explained the whole story.

Mrs. Jia Zhang didn't listen to this. She held her waist with both hands and pointed at Yi Zhonghai's nose and said, "Well, you won't have any share of my bananas today."

She'll eat an extra banana later, so happy!
"Banana?" Yi Zhonghai then saw Jia Dongxu holding three bananas in his hand.

Yi Zhonghai looked at Jia Dongxu: "Apprentice, this banana."

Jia Dongxu looked at Jia Zhang and then at Yi Zhonghai. After hesitating for a moment, he stepped forward and handed a banana to Yi Zhonghai.

"Master, you are old and have bad teeth. I give you this banana."

Yi Zhonghai was in his prime at this time, and he was strong and strong. It had nothing to do with his bad teeth, but when he heard these words, he felt warm in his heart.

Son, this is a true son.

Yi Zhonghai felt a surge of heat in his heart, his nose was sore, and tears almost overflowed.

"Dongxu, okay, okay, you are a good boy!"

Jia Zhang saw that Jia Dongxu was disobedient, but there was nothing she could do. Now she had to live by her son.

There were two bananas left, and there were three people in the Jia family. They were divided unevenly, and they couldn't kill one of them with a kitchen knife.

After some overall planning, equal distribution, and calculation of length, Yi Zhonghai got one banana, Jia Dongxu got one, Jia Zhang got half, and Qin Huairu and Banggan got Banggan.

After dividing the bananas, Mrs. Jia Zhang thought for a while and said: "Qin Huairu, your family has taken advantage of it this time. After we finish eating, you can send the banana peels back to your parents' house and let your mother-in-law and father-in-law have a taste of it." taste.”

Qin Huairu looked down at the banana peel covered with black spots and fell silent.

Not long ago, the Jia family was in a state of collapse, and it was Qin Huairu who came home and brought thirty kilograms of stick noodles to relieve the famine.

She felt that Jia Zhang looked down on her natal family.

The most excited person at this meeting is Yi Zhonghai. This is a banana given by his son, and it must be particularly sweet.

Yi Zhonghai picked up the banana and was about to peel it, but Jia Dongxu stopped him.

"Master, isn't it too ceremonial for us to just hide at home and eat?"

"what do you mean?"

"Let's go eat bananas by the pool!" Jia Dongxu smiled happily.
