Rebirth 84, starting from fish farming

When Lu Changhua returned to Beining, his focus fell on the research and development of new cars.

The new engine from the engine factory has completed acceptance.

The production license has also been issued.

The tractor factory is optimizing new models.

Tractors are agricultural vehicles that travel on dirt roads in the countryside and carry loads in the fields during operations.

The biggest requirement is that it must be able to cope with the most extreme operating environments.

In the Northeast, the biggest enemies of tractors are waterlogging and icy and snowy roads.

After heavy rain, if waterlogging is not drained in time, waterlogging will occur.

The tractor cannot move at all.

At this time, it is necessary to "change the shoes" of the tractor.

The Northeast is called "Bigfoot".

The actual process is to replace wheeled agricultural machinery with chain rails.

These things came into existence a few years ago to deal with waterlogging.

But even with "big feet", it still doesn't work when waterlogging is severe.

Should the car be stuck or the car should be stuck?

In response to this situation, Changhe Tractor Factory's new 18-horsepower model has been improved.

One is to increase the width of the front and rear tires and deepen the tire tread.

This initiative requires substantial financial support.

This is equivalent to developing new tires specifically for new car models.

If the tires are widened, the wheels will need to be customized.

Fortunately, the rear axle factory is ready for trial production.

Originally they did not produce wheels, but now they have no choice but to rely on themselves.

As the tires become larger, the transmission system of the rear axle must be redesigned, which involves power matching issues.

Gearbox manufacturers are also working hard to adjust the transmission ratio of gearboxes.

All to accommodate brand new tires.

There is also a differential lock issue here.

The previous 12-horsepower small four-wheel tractor had a belt drive.

There are advantages and disadvantages.

The advantage is that there is a soft connection and soft transmission between the engine and the gearbox, which can reduce losses when the engine or gearbox fails.

The disadvantage is that the engine's power will be lost during transmission.

The 12-horsepower tractor produced by Changhe Factory at that time also had this transmission mode.

The later 14 horsepower was still belt driven.

The current 18-horsepower new model has undergone fundamental changes and has been changed to a hard link. It is driven by the front and rear drive shafts.

Agricultural tractors need to be used for multiple purposes.

Not only can it be used in fields, but it can also be mounted on a rear trailer and transported on the highway.

This is the requirement of actual usage in rural areas now.

For this purpose, the car is equipped with an air pump.

When working in the field, the tire pressure needs to be reduced, and when transporting on the road, the tires need to be inflated.

This tractor is the application of the latest technology of Changhe Factory.

Especially the appearance of the new rubber "big feet".

The "big feet" of large combine harvesters in the Northeast Reclamation Area are all made of iron or steel chain rails, shaped into a triangle.

It is heavy and can easily get stuck in the car, so the effect is limited.

Think about it, Dongfanghong's tractor has already gotten stuck. If your harvester is replaced with the big legs of the tractor, won't it still get stuck?!

The rubber feet designed by Changhe Factory completely broke the tradition.

It does not need to change wheels, but has rubber feet hanging outside the tires.

Just put a pair of big shoes on the tires.

In order to develop this pair of shoes, Chen Liguo and Sergey's hair turned gray.

As we all know, rubber is very soft, and to be wear-resistant, other wear-resistant materials need to be added.

There also needs to be lining bones, otherwise the rubber chain rail cannot be made at all.

Several times they suggested that they simply use steel, which would be simpler.

But Lu Changhua just disagreed.

Lu Changhua told them the main reason many times.

One is to reduce its own weight, and the other is to reduce the gap between the big foot chain rails so that the rubber foot can remove mud and increase power output.

Finally, Lu Changhua came up with an idea.

Can steel ribs be added to each piece of rubber chain rail to increase their support in this way?

They jointly designed and developed with tire manufacturers and finally made a set of rubber feet.

This set of big feet is placed directly on the tire.

On the basis of the 80cm wide tire, 20cm are added to both sides.

Forming an extra wide foot of 120 cm.

After the vehicle was assembled, actual testing was conducted.

Under heavy load conditions, the 18-horsepower wheeled tractor has excellent power output and strong passability.

It has even stronger adhesion on icy and snowy roads.

Experts from the province were surprised when they saw the prototype car.

A small four-wheel tractor was played with tricks by Changhe Factory.

It can be said that it is not inferior to foreign advanced tractors at all.

When applying for a production license from the Agricultural Machinery Bureau of the Ministry of Agriculture, experts from the Agricultural Machinery Bureau were surprised.

Lu Changhua only saw applications in tractor production.

And agricultural machinery experts have seen even more.

Soon experts from the logistics department rushed to Changhe Tractor Factory.

Visited this new model.

I even drove it myself.

When Chen Liguo told Lu Changhua the news, Xiao Lu was busy making a villain with Wang Yao.

He hurriedly came to the factory.

The military industry expert smiled and asked: "Mr. Lu, can your big feet be transformed into chain rails for tanks and armored personnel carriers?"

Upon hearing this, Lu Changhua was shocked.

"Our technology is not yet mature, especially the materials and processes are not perfect, so I'm afraid we won't be able to meet your requirements."

Why did Lu Changhua say this?

The main reason is that the big feet of agricultural tractors walk in mud, and the wear resistance of the chain rails is not high.

If it is equipped on tanks and personnel carriers, its wear resistance requirements will be too high.

It has to adapt to many gravel roads.

Lu Changhua knew that his product completely failed to meet military industry standards.

If they were to be re-developed, they would have to be killed.

We are just a tractor factory, not a tank factory.

Faced with Lu Changhua's rejection, these experts all nodded and did not embarrass them.

The Agricultural Machinery Bureau issued a production license quickly.

Lu Changhua rushed to build three prototype cars and held a new car launch conference in Bac Ninh for the three northeastern provinces.

Leaders and experts from agricultural machinery exports in each province were invited, as well as business personnel from agricultural machinery companies.

Beining became lively for a while.

The red flag is fluttering and the gongs and drums are noisy.

Provincial and municipal TV stations are hyping up the news about the launch of new products from Changhe Tractor Factory.

Bac Ninh has also received a large number of users who want to reserve vehicles.

Last year, the 14-horsepower tractor from Changhe Factory became a good helper for many farmers.

Coupled with advertising and installment payments, sales increased significantly, and he immediately became famous.

Immediately afterwards, the launch of 18 horsepower this year attracted a large number of consumers.

This model not only continues the installment policy, but also provides solutions to the pain points of many farmers.

Rubber feet are optional equipment and can be installed optionally.

The bare car price is RMB 50,000, with options increasing by RMB 5,000.

Purchased separately from an agricultural machinery company for 8,000 yuan.

When buying a car, one-time options are cheaper and the discounts are huge.

Changhe Factory's sales method this time is a little different from before.

Adopted a pre-sale method.

Promise to get the car within a month.

For a time, reservations were very enthusiastic.

The big competitors in the industry say the grapes are sour and use various methods to slander Changhe Tractor.

Said that the optional accessories of new models are IQ tax and not practical.

He said that the price of cars is too high, which is squeezing farmers' hard-earned money.

He said that many functions are unnecessary and are just excuses for the high price. It is better to be simple and practical.

Wait, that's all.

For this reason, Lu Changhua invested heavily in CCTV and bought the news time and title.

"Changhe Tractor reminds you that it is Beijing time..."

Now all the rumors have been dispelled.

This 18-horsepower four-wheel tractor takes into account the dual functions of farm work and road transportation, truly realizing one vehicle with multiple uses.

There are orders for tens of thousands of units from the three northeastern provinces alone.

Chen Liguo led the marketing team to conquer the capital again.

Agricultural machinery experts and agricultural machinery companies from all over North China are strongly invited to attend the ordering meeting.

Originally, Chen Liguo should not have been involved in this kind of thing. He was in charge of more than a dozen factories and was simply too busy.

However, there is no way, who makes Hu Dagui, who is in charge of this matter, have no time!

Wu Yue is going to give birth in the next few days.

Lu Changhua couldn't bear to let his good brother go to the capital at this time.

Just go to Lao Chen.

Of course Hu Dagui was grateful.

Wu Yue was admitted to the hospital, Hu Dagui asked for leave to accompany her, and Aunt Hu also rushed over from the three-point court to help.

Wang Yao went to the hospital several times.

Nowadays, most people take the time to go to the hospital when they have a baby.

I won’t go until it’s time to give birth.

Why?

It's still about money.

Hu Dagui was not short of money, so he sent his wife to the hospital early.

I've been here for two days and the baby hasn't been born yet.

Lu Changhua was reading reports in the office when the phone rang.

When I picked him up, it was Hu Dagui.

"Changhua, it's time to give birth, come quickly."

"Ah, is it real this time?"

"Zhen Sheng, the doctor has already pushed Wu Yue into the delivery room."

"Okay, come right away."

Lu Changhua quickly called Wang Yao, took nutritional supplements and went straight to the hospital.

As soon as the two rushed to the door of the delivery room, they saw Hu Dagui leaning against the wall and squatting on the ground, his hands and feet trembling.

Uncle Hu arrived at some unknown time and was walking in circles in the corridor.

"Oh, old man, please stop turning around. It makes me dizzy."

"Why haven't you given birth yet?"

Old Hutou rubbed his hands with an anxious look on his face.

"Wu Yue's family, who are Wu Yue's family?"

"I, I."

Hu Dagui stood up.

"If the fetus is in an incorrect position, it may be life-threatening. Please sign."

When Hu Dagui heard this, his legs became weak.

Lu Changhua said: "Hurry up and sign, it will be fine."

He has already experienced such a situation and has some experience.

After signing, Hu Dagui slid to the ground against the wall as if his spine had been broken.

Seeing that his face was pale, Lu Changhua comforted him.

"Don't be afraid. Doctors tell everyone this. They are afraid of taking responsibility and everyone has to sign."

"I, I feel panicked."

Hu Dagui has long lost his careless look.

"Don't panic, I'm here, don't be afraid."

Wang Yao also came to comfort him.

After only eight or nine minutes, a loud cry came from the delivery room.

"It sounds like a son."

Lu Changhua said to himself.

Hu Dagui then stood up and held Lu Changhua's shoulders.

"son?"

"Like a son."
