Rebirth 84, starting from fish farming

Chapter 274 18 horsepower explodes again

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

The engine factory's new engine has completed acceptance.

The production license has also been issued.

Tractor factories are 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 couldn't move at all.

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

The Northeast is called "Bigfoot".

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

These things were put in place a few years ago to deal with waterlogging.

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

The car should be stuck or the car should be stuck.

For this situation, the new 18-horsepower model of Changhe Tractor Factory has been improved.

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

This initiative requires significant 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 the 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 is 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.Driven by front and rear drive shafts.

Agricultural tractors require multiple uses.

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

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

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

When working in the field, the tire pressure should be reduced, and when transporting on the road, the tires should 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 it is easy to get stuck in the car, and the effect is limited.

Think about it, the Dongfanghong tractor is stuck, if you replace the harvester with the big feet 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.

It’s about putting 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 other wear-resistant materials need to be added to be wear-resistant.

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 the dead 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 attaches directly to 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 carried out.

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.

A small four-wheel tractor was played 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 also drove it myself.

When Chen Liguo told Lu Changhua the news, Xiao Lu was busy making villains 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 a lot of 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, as well as business personnel from agricultural machinery companies, were invited.

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 became famous at once.

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 optional.

The bare car price is RMB 5, with options increasing by RMB 5000.

Purchased separately from an agricultural machinery company for 8000 yuan.

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

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

Adopted pre-sale method.

Promise to get the car within a month.

For a time, reservations were very enthusiastic.

The big manufacturers in the same industry say that the grapes are sour, and they 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, there's more.

To this end, Lu Changhua invested heavily in CCTV and bought the news time 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 tens of thousands of orders 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 him, and Aunt Hu also came from the three-point court to help.

Wang Yao went to the hospital several times.

Nowadays, when most people give birth to a baby, they squeeze in time to go to the hospital.

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 the report 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 and went straight to the hospital with nutritional supplements.

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?"

"me."

Hu Dagui stood up.

"The fetal position is incorrect and may be life-threatening. Please sign."

When Hu Dagui heard this, his legs became weak.

Lu Changhua said: "Hurry up and sign, it's okay."

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 backbone was 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 no longer looked carefree.

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

Wang Yao also came to comfort her.

After only eight or nine minutes, a loud cry suddenly 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."
