Back at the hotel, Xiao Yifei proudly uploaded today's masterpiece, and now those who sprayed him to smear Paris had nothing to say. Thinking about it carefully, Xiao Yifei is still a little afraid, fortunately, the two black men don't have guns today, otherwise he would have to confront others with an empty old pistol, which sounds terrible.

In the end, through William, he got a box of bullets from his classmates, and now Xiao Yifei has a self-defense weapon and can travel everywhere with peace of mind.

The next afternoon, when the tour group was evacuated, Xiao Yifei slowly followed the guide map and slowly admired the Louvre. At this time, there were very few people, and some exhibition halls were even the only one Xiao Yifei, who slowly admired the artworks around him. He actually found a lot of ancient Egyptian things here, and even a shrine dedicated to Osiris, as well as a statue of Osiris, and even a statue of her wife Isis breastfeeding her son.

In the next few days, Xiao Yifei found a good means of transportation, the happy double-decker tourist bus (openTourBus), which can take this thing to see the cityscape of Paris on his own. There are also Chinese guide headphones in the bus, and you can get on and off each attraction freely, and there is a bus every 10 minutes, and there is no limit to the number of rides on the day.

Xiao Yifei chose the green line, starting from Place Madeleine, passing through the Opéra, the Grand Palais, the Louvre, Notre Dame Cathedral, the Place de la Concorde, the Arc de Triomphe, the Palais de Chaillot, the Eiffel Tower, Les Invalides and back to the starting point. On this route, Xiao Yifei basically includes all the attractions he wants to visit, and the route has been driving in a relatively safe area.

After almost shopping in Paris, Xiao Yifei felt that it was time to do business.

Since he decided to buy a winery, Xiao Yifei had to make some use of the space. Although Xiao Yifei has not yet inspected the vineyard on the spot, he also saw a lot of pictures when he checked the information. After pruning, the grapes grow along the shelves and are comfortable to look at.

Xiao Yifei has never understood what is going on in the space, you have to say that these grapes are not artificially grown, but in the space these are obviously Pinot Noir and Chardonnay, and these two grapes are the main varieties of Burgundy. It can be said that grapes are grown, but even if no one takes care of them for a long time, the traces of artificial planting should still be visible. The grapes in the space apparently began to creep from the moment they emerged, and the aerial roots of the grapes growing next to the ground were planted into the ground to form a new plant, leaving the entire vineyard intertwined.

The only thing Xiao Yifei can do now is to destroy the vineyards in the space and replant them.

Some people may think that there are grapes when there are grapes, and they are fortified varieties, so why should they be eradicated and replanted?

Xiao Yifei also checked the wine history of various countries after settling down to build a winery, and found that there was once a deadly disease that had caused a devastating blow to the wine industry in various countries, that is, phylloxera. The disease swept across Europe at the end of the 19th century, and only a handful of vineyards across the continent were spared its ravage, while others had to be uprooted and replanted. Those vineyards that have escaped phylloxera are not carefully cared for every year, for fear that they will be accidentally hit.

Although these vines in the space have escaped phylloxera, once transplanted, they are likely to be destroyed by phylloxera, and they will need to be replanted at that time.

Moreover, Xiao Yifei has always felt that the development of science and technology is getting faster and faster, and the varieties of various crops are getting better and better, and it is not right to always hold the idea that something decades or hundreds of years ago is good. The most obvious example is what the yield of wheat and rice was decades ago, and what is the yield now, in addition to factors such as water and fertilizer, seeds are also an important factor.

Therefore, Xiao Yifei does not think that the Pinot Noir and Chardonnay in the space are necessarily better than the ones that are planted now.

It is not a simple matter for the vineyards in the space to be torn down and rebuilt.

Decades old vines, the root system must be very developed, the thick rhizomes are thicker than the calves, if these rhizomes are not dug out, they will grow side branches, not to mention, it is very troublesome to plow every time, but to dig them up, you must have a small excavator and other things, otherwise you can only let Xiao Yifei take a shovel and dig the pit slowly by himself.

Excavator this kind of construction machinery is not inferior to our country's products, Xiao Yifei was going to buy it after returning to China, but he just saw the news about the construction machinery exhibition on TV a few days ago, several excavators lined up in the outdoor booth in the news screen, and a small excavator in the venue showed their skills, a well-known machinery brand such as Caterpillar, JcB, Volvo, Hitachi, Komatsu, Hyundai have appeared, and the domestic Sany, XCMG, Liugong, etc. have also flashed a shot.

Xiao Yifei carefully checked and knew that the French International Construction Machinery Exhibition (InTeRmaT2009) is now being held at the Villepinte Exhibition Center near Charles de Gaulle Airport in the north of Paris, which was founded in 1988 and is one of the three famous exhibitions in the field of construction machinery and construction machinery in the world, which is only held once every three years.

Xiao Yifei looked at the time, today is the last day of the exhibition. Anyway, I'm going to buy an excavator, go check it out. So he made a phone call to Hussein, an Arab driver who drove a Mercedes AMG taxi.

It is worthy of the construction machinery exhibition, just enter the gate, a behemoth, tall and giant will come into view, on the construction site seems to be huge large excavators, bulldozers, mixers next to the high crawler crane, crane, pile driver under the comparison has also become a small toy, the highest is actually a cement pump truck, 72 meters high, much higher than the exhibition hall more than 20 meters high, Xiao Yifei walked slowly to the front, found that this pile is actually domestic goods, and the highest pump truck is Sany Heavy Industry. It seems that domestic construction machinery has been thoroughly developed.

After all, it is a professional exhibition, and the number of visitors is not large, so Xiao Yifei has enough time to take pictures slowly. After visiting this outdoor exhibition area, Xiao Yifei entered an indoor exhibition hall, which is a foreign exhibition area, in addition to many mechanical parts manufacturers, Caterpillar and Volvo actually got a few excavators in this exhibition hall. The size of the machine is really relative, and in the indoor exhibition hall, without the backdrop of larger machinery, these big guys suddenly show their huge body that needs to be looked up to.

The big TV next to it keeps playing the promotional videos of various manufacturers,It seems that now the concept of environmental protection is becoming more and more deeply rooted in the hearts of the people,Many manufacturers have begun to play the banner of hybrid power,Claiming that their products are energy-saving and emission reduction。

In addition to machinery manufacturers, there are also many exhibition halls of print and online media, which distribute information when they see people, and Xiao Yifei is stuffed with several magazines and brochures after a while.

Walking around, Xiao Yifei came to another exhibition hall, and Xiao Yifei found that there was a large group of people around the booth here, and Xiao Yifei came over curiously.

It turned out to be a small excavator dancing.

It is really dancing, in the melodious music, this small excavator sometimes rotates the turntable, sometimes relies on the crawler to rotate the circle, sometimes telescopic the excavator arm, and sometimes stands on the side of the front and back left and right under the support of the excavator arm. The crowd around them burst into applause from time to time.

Xiao Yifei found that there was no one sitting in this excavator, remote-controlled?

At this time, Xiao Yifei found that there was a staff member who looked like a Chinese next to him holding a tablet in his hand, could it be that this is also a domestic product? Xiao Yifei swept around, and finally saw the Chinese logo, which turned out to be really domestic, and it was a "Shanhe Intelligence" company.

I saw the operator scratching the flat with his two thumbs, and the excavator dancing with his gesture. Coupled with a camera on the top of the driver's seat, it's clear that this little dig really has a remote control function.

Xiao Yifei quickly discovered another peculiarity, this thing actually has no engine sound, only a low humming sound, could this also be a hybrid power?

Soon the music ended, the operator also put down the tablet, and began to give a brief introduction and explanation, to Xiao Yifei's surprise, this small dig is actually all-electric.

"Our intelligent excavator sweRoB2009 effectively combines multi-sensor data fusion technology, wireless aP technology, remote control technology, virtual instrument technology, robot control technology, sound, light, electricity, etc."

"The whole machine is battery-powered and has zero emissions. The instrumentation system is based on ergonomic design; The whole machine adopts electro-hydraulic proportional technology and has good controllability. In the case of wireless remote control, the control distance can be greater than 500 meters; The remote data and image transmission function realizes the remote data and image transmission function of the on-board controller and the host computer, with good real-time performance and high reliability. ”

After saying these two paragraphs, he picked up the slab and tinkered with it a few times, and the excavator did a simulated digging, lifting, rotating, and unloading action under his control. Then he lowered the slab, but the excavator was still repeating the action automatically, and after digging a few shovels, it automatically retreated a certain distance and continued to dig. It's amazing.

"This is the intelligent control system of our excavator's self-learning function, which can learn the operator's movements online, and automatically repeat all actions with high precision, and can also carry out simple autonomous operation."

This is when he picked up the tablet again, and with a stroke of his hand, the excavator immediately stopped its current action and turned in a circle. A little more, the excavator immediately began to move again.

"We have also realized the redundant control of multiple modes of the excavation robot, which ensures safety performance and reliability, and improves the level of automation."

Xiao Yifei was very excited, this thing was really suitable for him, and he immediately raised his hand and asked:

"Do you have any presets for digging a hole or a tree?"

The narrator was stunned for a moment, glanced at Xiao Yifei, probably a little surprised that he, a yellow-skinned man, asked questions in English, but he still said:

"Of course, there are also actions such as digging ditches that have just been demonstrated."

He then asked about the electricity part he was most concerned about:

"What about the battery capacity?"

"We use a 48V battery for power supply, which can ensure 4 hours of work after being fully charged."

"Can I work while charging?"

"Yes, but we don't recommend it, because it's dangerous to drag wires in the back."

Xiao Yifei can't wait to buy it right away, as long as he has this, he can easily dig out the roots of the vines that are buried deep in the ground, and the best thing is that it is fully electric, and there is no pollution problem of diesel engines at all. After all, the Osiris space is closed, if the combustion of the diesel engine is not sufficient, it is easy to have carbon monoxide, carbon particles and other pollutants, if the diesel is used too much, so that the space has haze, PM2.5 and other problems, then Xiao Yifei does not know what to do.

Xiao Yifei left the crowd of visitors and came to the booth.

"I want to buy an excavator."

The salesperson at the booth probably hadn't seen this kind of person who was about to buy goods at the exhibition, but he quickly came to his senses:

"Which model, please?"

"That's the smart little excavator that performed."

This intelligent digging is Sunward intelligence just developed a product, it can be said that they have made a big attempt in independent research and development, scientific and technological innovation, originally brought it to the exhibition this time, just to show their own level, the main force of sales or in other excavators and loading machinery. But I didn't expect that there would be customers coming to the door now.

After some negotiations, the salesman thought that it would cost the machine to return to China, and it would be good to sell it on the spot, so he went to ask the leader. Soon, Xiao Yifei signed a check, this set of equipment belongs to Xiao Yifei, and when the exhibition is over in the afternoon, he will send it to Xiao Yifei.

So Xiao Yifei could only leave the exhibition, call Hussein back, and take him to a nearby temporary rented warehouse. At the end of the afternoon exhibition, a trailer came to the warehouse with this small excavator more than 3 meters long, more than 1 meter wide, more than 2 meters high, and weighing only 1.8 tons.

After the trailer left, Xiao Yifei sent the small dig into the space, and learned how to operate it after a while.

Standing on the ground, using a tablet to control the excavator slowly into the vineyard, to a calf-thick vine, Xiao Yifei slowly began to dig, an hour later, a deep pit appeared, and the roots of the 1 and a half meters of grapevine were exposed. Xiao Yifei brought a rope to connect the roots of the tree to the bucket, and as the digging arm was raised, the deeper taproot was torn off and the stump was hoisted out.

Xiao Yifei is very happy, this thing is really easy to use, if Xiao Yifei uses a shovel to dig it by himself, I don't know how long it will take to dig one.

It's a pity that he claimed to be able to use 4 hours of electricity, but he tossed it up in more than two hours, and Xiao Yifei can't get it out to charge it now. At this time, he desperately hoped that there would be electricity in the space and he could continue to work. Forget it, there is no hurry at this time, wait to return to China and slowly dig the ground, it is best to buy another one, so that you can charge one and work the other, or just find a way to make the space have electricity. But if you use diesel to generate electricity, what is the difference between using diesel excavators directly?
