Section 532
Made into a funnel-shaped cylinder.
"Well... if conditions permit, it's best to bake it, which will make it more durable. If you don't have that condition, you can use it directly, but before use, it's best to dry it by the fire."
After speaking, Lu Yu took the fan blades he had made before and placed them in the fan casing.
And turn the shell upside down.
At this time, the drill rod on the fan blade can just pass through the round hole at the bottom.
As long as the drill pipe is rubbed, the wind generated by the fan blades can be blown out along the spout of the fan.
And then heat up the fireworks!
In order to prove the feasibility of the wind turbine, Lu Yu held the drill pipe tightly and gave a rough demonstration to the audience.
"Huhuhu——!"
result.
As expected.
As the fan blades inside the fan rotate, the flames of the bonfire burn brighter and brighter.
Whirring sound!
Very rhythmic!
Seeing this scene in front of them, the audience's eyes lit up.
Barrages were launched one after another:
"666666666666666!"
"Trench digging, and such awesome operations!"
"Nima, the blower is ready!"
"Anchor, you were the bearer of the Mingjiao Fire Flag in your last life, right?!"
"It blinded my titanium alloy dog's eyes!"
"Awesome!"
Chapter 393 Use a bow, drill, and blast to build a furnace! (Please subscribe!)
A simple piece of bark,
Can you play so many tricks?
Just a slight makeover.
Just become a blower?
This is too awesome!
Seeing Lu Yu's actions.
There was an uproar in the live broadcast room instantly, and all kinds of gifts came out one after another. The commotion lasted for a long time before it calmed down!
but.
Amid the admiration, many water friends said:
This type of blower with built-in fan blades is so inconvenient.
You can only work by rubbing it with your hands constantly.
If this guy was used to heat up the charcoal fire, wouldn't he be able to do the job if he hadn't been single for fifty years and had quick hands?
The most important thing is that it’s tiring to watch!
Copper smelting is a big project. When will it be completed?
Faced with doubts from some viewers.
Lu Yu smiled knowingly.
To signal everyone not to rush:
"Everyone, this is just a semi-finished product, please be patient and read on -"
Said.
He turned around and found a few branches of different lengths.
A small wooden frame in the shape of a "door" was built with bark rope.
Placed above the blower.
Then, he took out the spindle he had made during weaving.
"Remember this spindle?"
"When I was building the loom, I once said that in addition to turning silk thread into hemp rope, the spindle can also be used as a bow drill."
"If we apply it to blowers, the problems that everyone is concerned about will naturally be solved."
Bow drill, as the name suggests, is drilled with a bow.
Mostly used for drilling wood to make fire.
This method of making fire should be one of the most convenient and quickest methods of drilling wood to make fire.
save time and energy.
Extremely efficient.
Much more powerful than a hand drill.
In addition, bow drills can perfectly replace human labor in other aspects.
Automatic blowers are one of them.
While talking.
Lu Yu holds a spindle.
Remove the lower round stone plate.
I found a piece of bark rope and tied it to both ends, transforming it into a wooden bow.
Then, the tree rope bowstring is wrapped around the drill pipe of the fan.
Together they were fixed on a small wooden frame.
This way.
Just hold one end of the bow drill with your hand and keep pushing and pulling.
The fan blades of the blower will naturally rotate accordingly!
Not only is the wind strong and persistent.
The most important thing is that this is much less laborious than simply rubbing it with your hands!
After finishing it, Lu Yu didn't say much and just demonstrated it to the audience on the spot!
in the screen.
As the bow string is drawn and released.
The fan blades in the casing sometimes rotate forward and sometimes reverse.
In an instant.
The sound of whistling wind came from the air outlet, and within a short time the fire was turning red!
See this picture.
The audience's eyes suddenly brightened, and they left messages on the barrage:
"Damn! That's great!"
"This blower is invincible!"
"How clever!"
"666666666"
“The anchor’s manual skills are really strong!”
"This wind is as powerful as a five-speed electric fan!"
"You know so much from upstairs? Are you having a good time?"
"Hahahahahaha!"
…
soon.
After a large number of gifts, Lu Yu simply thanked him:
"Thank you everyone for your gifts."
"Actually, this is just a very simple automatic blower, not difficult to make at all."
"The main structure, including the fan blades and shell, are all made of materials that are usually readily available."
"The principle is even more simple and clear, and any normal person can imagine it."
"However, in order to perfectly apply simple principles to daily production and life, in addition to being good at discovery, you must also dare to try."
"Because in the final analysis, it is attempts again and again that have brought human civilization from poverty to today."
"How's it going, guys? Isn't this blower interesting?"
More than interesting.
It’s so awesome!
This simple principle is known to everyone, and with a few inconspicuous things put together, you can play so many tricks.
You really can't help but accept it!
This scene almost perfectly interprets the unique charm of primitive survival——
