There was a knock on the door from Beehill's villa. Good (if) book {bar} the fastest update on the whole network Xiao Yifei rubbed his eyes, struggled to get up, and shook his head that was still a little hungover. Hey, that's the way it is in a small place, the manager and the bartender would agree to change the wine, and he actually drank too much.

"Shaw, are you up?"

"David, what's the matter?"

"You called you last night when you said the construction team was coming, and now they're here."

Oh, Xiao Yifei finally remembered, he glanced at the clock on the bedside table, and it was actually 9 o'clock.

"Okay, I'll be here right away, you guys do it first."

After playing with the black nose for a while, it followed Xiao Yifei to the vineyard.

According to the construction plan, today is the time to enter the 50-acre vineyard to lay drip irrigation pipes, and by the time Xiao Yifei arrived, the workers had already begun to work. They are removing the original trellises in the vineyard.

Because the grapes of the Ivy family are retailed in the market, the profit margin is much lower than that of Monterena, a winery that makes its own wine, and their investment in the vineyard is much smaller, and the facilities are not as willing to renew as the winery, so their grape trellises are very old, and some of the trellises are tied with wooden strips when they are broken, so this vineyard improvement should be updated with new cement piles and steel wires.

After the winter pruning, only the arms are still tied to the first wire, and the other branches tied to the second and third wires have been cut off, leaving only a few centimeters long with one or two slabs on which they will grow into new shoots in the spring.

At this time, it is easiest to replace the fence, you only need to cut the wire with a wire cutter, let the arms off the wire, and the whole fence can be removed. After the wire is cut, everyone cuts the wire between the two cement piles and drags it to the ground, so that the cement pile can be dug now.

Once the demolition is complete, the next step is to erect a new fence. When Xiao Yifei erected the fence in the space, he used the excavator's bucket to smash the cement piles into the soil, although now the vineyard cannot enter the excavator. But they have a special tool, a hand-held pneumatic pile driver.

Two black, strong black men came with a piston compressor in tow.

"Holy, this guy has to be 300 pounds."

Overseer David nodded:

"Well, I guess it's more than that."

Xiao Yifei suddenly felt a little understanding, why sometimes criminals in the United States police don't have guns. They're going to shoot too. The two tall and strong guys in front of you, if you make threatening actions against people from a distance of 5 meters, or even do nothing, they will stare at you fiercely, and anyone will mumble in their hearts.

In fact, Xiao Yifei has also seen strong men. For example, the sa in NCISLA, but although he is strong, his height is about the same as Xiao Yifei, and he is only about 188, so he looks less threatening. But this guy is estimated to be 2 meters, that is, as tall as Dwayne Johnson, and about 40 pounds fatter than him. Xiao Yifei thought that maybe the so-called strong men who came to China to make money during the Republic of China are probably just this virtue.

A sudden sound sounded, and two big men stood on the iron bench with a pile driver. A man below held on to the cement pile, and with the sound of a soaring impact, the cement pile drilled into the soil at a speed visible to the naked eye. Looking at the flesh of the two big black men shaking rhythmically and rhythmically with the vibration of the machine, it actually showed a kind of ripple. With a sound of dark skin, under the sun, for some reason, Xiao Yifei felt as if a crude oil pond was sparkling.

Xiao Yifei sneered and laughed. David asked curiously:

"What's wrong?"

Xiao Yifei waved his hand again and again:

"It's okay, I suddenly remembered an advertisement in our country, good figure, throw it out. Crazy Fat Throwing Machine ......"

David inexplicably looked at Xiao Yifei and said Chinese, Xiao Yifei could only tell him about this advertisement and fat throwing machine, who knew that this old man said disapprovingly:

"This was popular in my dad's time."

Xiao Yifei happened to be drinking water, and almost choked on a mouthful of water. David is in his 50s. Wasn't his father's era during World War II?

Seeing that Xiao Yifei couldn't do it, David shook his head:

"Isn't there an Internet now, you can find it on the Internet yourself. That stuff doesn't work at all, you see me, I don't do any exercise at all. The body is not so good. ”

You're really good, and you can go bear hunting.

This time, the workers installed 6 wires, and on top of the original third road, that is, the top of the cement pile, they installed two wires to make the spacing of the grape branches more sparse and ensure that each branch can enjoy the sun. It turns out that the first wire at the bottom, that is, under the arms of the vine, is also installed with a wire, a soft plastic tube, also called a capillary, which is tied to the bottom wire with a thin wire, and a dropper is installed at the root of each grape.

The workers moved quickly, and in a short time they were installed in a row, connecting the capillary pipes to the valves, and then to the branch pipes laid out at the edge of the vineyard. When the valve is opened, the dropper begins to drip down, and the soil at the roots of the vines is moist in a moment. David checked the droppers one by one, then closed the valves, and the drip irrigation equipment was completed.

These 50 acres of vineyards cost more than 500 rows, enough for them to work for a long time. When they're done here, the pruners will cut the other plots, and they'll move to other plots.

With the roar of engines, a tall crane followed a convoy of vehicles.

In the built plot, not only is the garden company that installs drip irrigation busy, but there is also a team of companies busy next to it, they are busy replacing fans. Napa vineyards are home to huge fans, which are a great tool for winegrowers to combat frost.

The spring frosts were very damaging to the grapes. In early spring, they will grow into small spores of branches in the future, and if they encounter frost, they can easily freeze to death and frostbite. In winter, only one or two spores are left on each shoot, and in the event of severe frost, the vineyard's stripping rate will be greatly reduced, resulting in a reduction in yield.

There are many ways to get frost on the other side, the first and oldest is to raise the temperature of the vineyard, such as the kerosene stove that was once used. There are still a few samples of this thing, more than half a person tall, which are usually kept in the storeroom, and when there is frost, the workers urgently take them out and place them among the grape rows. Light a fire to heat up the cold air, raise the temperature of the vineyard and stop the frost. Unfortunately, this method is too polluting. It's not in line with the current concept of environmental protection, so Napa's laws no longer allow it.

The second is to use a fan. There are two kinds of fighting frost with a fan, one is direct confrontation and the other is borrowing.

In the past, the installation height of the old fan was about 4 meters high. propane power, which blows cold air away and prevents them from entering the vineyard; Or it is to blow the air out after the propane is burned and heated to resist the cold air. This is the adversarial type. The disadvantages of this fan are very obvious, the first is that it is not very efficient, and one fan can only protect an area of 10 acres in size. The second is that the noise is huge, more than 90 decibels, which is close to the lower limit of permanent hearing damage.

In October of this year, the Napa County Court decided a case in which the resort sued the neighboring vineyard fan for nuisance. According to resort guests, he felt like a lawnmower was roaring in his bedroom. Neighbors in the vineyard said the wind turbine was running as if an air raid alarm was sounding.

The second type of fan is the borrowing type. Cold air is in the lower layer. Hot air in the upper layers, this is a well-known phenomenon. The fan is set up at a very high height, usually more than 10 meters, and its function is to pull down the hot air from the upper layer and mix the hot air with the cold air below, so that the temperature of the mixed air will rise and the vineyard will not be frosted. The protection range of this fan is larger, and the high-tech design of the fan blades makes the noise of the machine only more than 70 decibels when running, which is near the upper limit of human ear comfort.

In addition to these two methods. There are also local tyrants' wineries that use helicopters, spray water to prevent freezing where there is no shortage of water, and use high-tech microwave heating and other methods to resist frost hazards. It's just that none of these are used at Napa Winery. The original fan of the Monterena winery was the former resistance type, and this time it will be replaced by the latter type.

This fan update. It was in Bo's update plan, and after Xiao Yifei took over, Xiao Gui Cao adopted these update plans. It's just that Xiao Yifei is more bold than him, and asks for the renewal of the propane gas tanks and pipelines that have been used for several years.

Because the vineyard area is relatively small, these fans are located in the middle of the vineyard. In order to facilitate maintenance, it is convenient for vehicles such as refueling to enter and exit. Half of the wind turbines were not planted with grapes, leaving them as a passage for vehicles.

Xiao Yifei had come to see it before, and beneath the rusty fan was a propane engine, and next to it was a huge white horizontal gas tank with propane gas stored inside. Propane has always been regarded as a by-product of oil and natural gas, and with the development of shale gas in recent years, propane production has increased, and the export of propane in the United States has not developed, so the amount of domestic propane and natural gas is increasing. The industrial application of propane in China has not developed, so propane has been reduced to household heating and a small amount of industrial use, which makes the price of propane as low as 85 cents a gallon, which is only one-third of gasoline, which is more affordable than electricity. And this thing has a high calorific value and a high engine horsepower, so everyone invariably uses propane in the vineyard to fuel the engine.

Workers have cut and removed the rusty old fans in the vineyard, so the demolition here is now slick. The removal of these pipelines, machinery, etc., thanks to the half row of blanks vacated by Ivey, allows all kinds of construction machinery to enter and exit the operation site smoothly, and also makes the work of erecting towers a lot easier today.

On the ground lies a huge round iron cylinder more than 10 meters long and more than 40 centimeters in diameter, which is welded by workers in the ground and is a frame for a huge fan. There is a transmission device inside the iron barrel, which is responsible for transmitting the power of the engine at the bottom to the fan blades at the top.

With the rumbling sound of the crane, the iron cylinder was erected, and the workers below used screws to fix it to the original cement seat. Two workers climbed the ladder outside the iron cylinder to the top, directing the crane to lift the two huge fiberglass fan blades into place, and then connected them to the transmission. The fan blades are installed at an angle to pull the upper layer of hot air down.

A van drove cautiously with the engine and new gas tanks and pipes. In fact, he didn't have to be so careful, after all, the distance used by Ivey's family was 3 meters, and there was a 6-meter-wide road for it to drive when there was an empty line, but the driver knew that once he touched the vine next to him, David would definitely deduct their company's money, and their company would definitely deduct their money.

Amid the beeping of cranes and the rumbling of engines, the engine and gas tank are in place, and then the pipes are installed. By the time they tested the airtightness, it was already afternoon.

A tractor comes in with a refueling device to refill the brand new gas tank. There are still workers working on the vineyard, and they just added the propane needed for this test to be on the safe side. After checking again, someone pressed the button, just like a car, and the electric motor drove the engine to turn twice. After confirming that the gas valve was finally opened, the button was pressed again, and the engine finally roared after two clicks.

After the engine stabilized, a worker closed the clutch, and the upper fan blades began to rotate, faster and faster, and the fan blades could clearly be heard swishing. More than 10 meters away, the mustard was blown from side to side by the wind. Xiao Yifei walked over, it was indeed windy, and the wind was not small, he couldn't help but shiver.

Press another button, and the fan on the top actually starts to turn its head. Hehe, this thing is really a big electric fan, and it actually has a shaking head function.

Then press another button, the fan on the top began to shake up and down again, and the wind also blew far and near, this thing is really good, no wonder the range of protection is larger than before.

Xiao Yifei took advantage of them to conduct the test, and deliberately went to various distances to experience how noisy it was. I found that this thing can still hear a relatively loud sound at a distance of 100 meters, the sound from a distance of 200 meters is almost like a person, and if it is 300 meters away, it will basically have no effect.

Xiao Yifei walked in and took a closer look at the machine. The power is actually as high as 100 horsepower, then their air outlet must be equipped with a muffler, otherwise it would not be so quiet.

In order to compare the difference between the old and new fans, Xiao Yifei took David to Bee Hill. There is a wind turbine 100 meters away on the east and west sides of the bee hill, and this time the replacement plan is to replace it in situ, which means that it will be surrounded by wind turbines in the future.

When David turned on the old fan, Xiao Yifei was startled, and the black nose ran away all at once. Why is this thing so loud, and the wind is obviously loud, coupled with the vibration of the shelf, Xiao Yifei's ears are almost deafened. He heard noticeably more sound at all distances than the sound of the new fan. He also went to Beehill Villa and immediately realized what it meant to "have a lawn mower in the bedroom".

And he felt that even if he changed to a new fan, the sound from 100 meters away was still a bit loud, and he didn't know how Jimmy had endured the old fan before. (To be continued.) It's like a book, the house of books! Unique URL:
