The aunts don't know about the difficult problems at the technical level.

I can't tell one, two, three.

All kinds of gossip information in the factory have listened to it.

Melon, wrapped, wrapped, wrapped.

Mrs. You lived in a family guest house for a week.

Once the accommodation fee is settled, it is only five yuan!

One week was enough for her to get a thorough understanding of the external environment of the No. 1 Machinery Factory.

Today, I have already packed my bags and plan to leave.

It's coming.

The charm of the thousand-year-old capital must be understood.

There are still thirty-six kilometers from the factory to the old town.

Leg walking, is impossible.

Fortunately, she is prepared.

Before coming, I got a new bicycle from Brother Yang.

A tall man of 1.7 meters, there is no problem at all in controlling the three or eight bars.

Riding crookedly for dozens of meters, he tamed the car with a brute force.

Under the scorching sun, I threw off the sweat in my palms.

The ancient city of Shendu, I'm here.

If you want to say that the landmark building of Los Angeles, it is the two-story drum tower located on the East Street of the Old City, which began in the Ming Dynasty.

Regardless of whether the drum tower is broken or not, she is punching in anyway!

Changxia Gate, Lijing Gate, Jianchun Gate, Fuwen Temple, and Chenghuang Temple, she all left a beautiful shadow.

Outside the ancient city.

White Horse Temple, she went!

The Buddha's feet in the Longmen Grottoes, she has embraced.

Hu spicy soup drunk.

It's really different from the peony swallow dish in the restaurant, she tasted it.

God is short of bread and flesh.

It's really not an era where you can order food at will.

The general rule is, what people have today, what you eat.

Anyway, she really behaved as a tourist for a few days.

During the day, he rode his bicycle around the alleys of the ancient city, taking pictures with his camera.

At night, she lies comfortably in the portable smart warehouse, sorting out the day's spoils.

If she has more time, she also visits the W Group's Agricultural Machinery Museum.

It's been a lot of times.

The vest of the "grocery store in the giant pit" was ripped out.

This is a global Internet celebrity!

Museums have turned intelligent customer service into human service.

W Group Agricultural Machinery Museum: [Dear guest, how can I help you?] 】

Grocery store in the giant pit: [Is there an introduction to the history of agricultural machinery in any earlier period?] 】

W Group Agricultural Machinery Museum: [Excuse me, how old do you want it to be?] 】

Grocery store in the giant pit: [Steam tractor, want to know about it!] 】

W Group Agricultural Machinery Museum: [Yes, yes, but that's another price.] 】

Knowledge pays, she understands!

So, You Tuhao received a video at a price hundreds of times more expensive than a ticket.

In the video, there is not only the manufacturing history of W Group.

It even dates back to the Industrial Revolution.

The video is more than three hours long.

She quickly rowed to the steam engine tractor that was most interested at this time.

The narrator is explaining how a steam tractor works.

[There is an oversized boiler in this position of its fuselage, as long as water is added to the boiler, it is heated by coal burning.

When the water heats up to a certain level, it is converted into water vapor at a super high pressure. Use water vapor to push the piston, and the engine is finished.

The earliest steam engines were only 25 horsepower, and they were bulky, bulky, and very slow.

The most obvious disadvantage is that the car is also prone to getting stuck in the mud after getting off the ground.

For a long time, when it was in use, it was necessary to have the steam engine located on the ridge of the fertile field, and the iron plough was pulled by a rope to work in the field.

After many improvements, it gradually became popular.

Until the middle of the twentieth century, the invention and application of the diesel internal combustion engine at the same time brought new opportunities for the development of tractors.

The advantages of diesel internal combustion engines are their simple structure, small size, and high power, which makes the operation of the tractor more convenient.

Tractors driven by internal combustion engines began to gradually replace steam tractors and became the mainstream.

Its horsepower also ranges from 25 to 100.

Tractors from the end of the twentieth century to the twenty-first century in the old era.

First, differential steering technology, power system, wet main clutch and other technologies are the core technology system.

Later, there is a technical system with electric fuel injection, high-pressure common rail fuel engine, power shift and other technologies as the core.

The models of tractors are also divided into light-duty and heavy-duty types.

In terms of function, it is divided into farmland special type and engineering type.

The horsepower of the special type of farmland is greater than 80, and the special tractor for engineering operations has more power output interfaces and machine interface in order to meet the special characteristics of engineering operations; Generally about 60~150 horsepower.

At the end of the Old Era.

Agricultural machinery has basically realized the information technology system, with clean energy, unmanned and intelligent, multi-functional operation.

Users value the functionality, environmental friendliness, safety and comfort of agricultural machinery.

After the new era of the global village.

Agricultural equipment from the environment, soil, wet and dry temperature to breeding, growth process management, to the final harvest.

There is no need for human intervention in the whole process.

Realized the large-scale, ultra-intelligent agricultural production management system based on the planting area]

I have to say that seeing the agricultural equipment in the global village today, someone who has been a vegetable farmer for ten years is drooling with jealousy.

If she had such a trading platform in addition to concentrate, she wouldn't have dominated the world's vegetable farms!

After reading the history of agricultural machinery, we will focus on the business of W Group.

The W Group, in the 20th century, was one of the first companies to develop internal combustion diesel tractors.

Now, 700 years later, its group business has covered all areas of agricultural machinery.

If you want to split these smart devices into functions, they can be roughly classified as:

Power machinery, construction machinery, tillage machinery, planting machinery, protection machinery, drainage and irrigation machinery, harvesting machinery, processing machinery, animal husbandry machinery, etc.

In the early 20th century, W Group's internal combustion diesel tractors (power machinery) quickly seized the agricultural market in Europe and the United States.

In the 21st and 22nd centuries, we have always wanted to develop in Asia, but we can't do it with cost-effective Chinese manufacturing.

Since the beginning of the 23rd century, they have used the power of capital to acquire almost all the companies with the strongest R&D capabilities in the industry.

A kingdom of super smart agricultural equipment has been formed.

To this day, it is still standing.

From the fact that they replaced the intelligent customer service with the management as a temporary customer service, we know that the sensitivity to business opportunities is not low at all.

Today's super agricultural equipment has to be used for decades.

The global market is unbelievably saturated.

Technology, it seems, has come to an end.

For several years, W Group's smart agriculture has not been innovated to a large extent.

The emergence of the "grocery store in the giant pit" has opened their eyes to a new business opportunity.
