Desert Island Survival Belt System

Chapter 296 323, there is a plane!

"Indeed...the way is not right." Qin Fengyi thought for a while, "Can we use mechanical tools to reduce the labor force?"

The emergence of machinery has reduced the labor force, such as the current computer embroidery, which can embroider various complicated patterns with just one button. If it is replaced by manual stitching, that person will definitely suffer from cervical spondylosis. .

There were also machines in ancient times, such as those small toys with wooden mechanisms in Qiyao Skills. It is said that there is a kind of mechanism bird that can fly in the sky without consuming energy, but simply flies with the help of airflow.

"Mechanical tools?" Lin Qingxue frowned and pondered, modern society cannot do without machinery, food, clothing, housing and transportation are inseparable!

Clocks, mobile phones, computers, and bicycles at home are all mechanical.

Generally speaking, the loom made by Qin Fengyi is a machine. Although it is made of wood, it is still a machine.

"Do you have a solution?" Han Xuening was looking at Qin Fengyi happily. Although this guy was unscrupulous and like a wild horse, he would always come up with some novel things sometimes.

"Do you know bicycles?" Qin Fengyi thought of a kind of machinery, which is something that almost everyone has come into contact with, bicycles!
"Bicycle..." Lin Qingxue and Han Xuening glanced at each other, and then suddenly their eyes lit up, and they both saw surprise in each other's eyes.

The principle of a bicycle is to step on the pedal, and the large gear connected to the pedal starts to rotate during the pedaling process, and the chain on the large gear drives the small gear integrated with the wheel.

The large gear rotates once, and the small gear rotates at least 10 times. Under the power of the pedals, driven by the gears and the chain, a strong rotational force is formed.

When the bicycle is idling, the large gear can make the wheels turn dozens of times at least once a week.

"You mean, you can use the principle of a bicycle to make a machine?" Lin Qingxue became more and more miraculous as she thought about it, and then she thought about it carefully.

Oh yes!

We are human beings. Although we don't know how to make bicycles, we have at least come into contact with them. Their principle is very simple. As long as we follow this principle, we can imitate this kind of mechanical equipment.

Human intelligence can only be more advanced from generation to generation. Just like people in the 50s seldom used computers, but people in the 70s basically knew how to use them. People in the 90s were more addicted to various mobile games, and the descendants have already started to play VR. up.

"Yes, we don't have a chain, but we have gears. As long as the pitch between the gears is close, it can be made into a machine!" Qin Fengyi opened the gear box, and there are still many gears inside. This is the gear box on the helicopter. A gearbox, using the rapid transition between the gear and the feed screw, adjusts the position of the gear, thereby forming different rotation speeds.

After searching for a long time, I found 2 gears. One gear was huge, about the diameter of a coconut, and the other was only the size of a paper cup.

The tooth pitches of the two gears were completely connected. After testing the gears, Qin Fengyi started to make this awesome mechanical tool.

The best thing to use is bamboo. Using the carpenter’s mortise and tenon technique, a very strange thing was made in a short time. This is part of the creation based on the principle of bicycles.

There is a crappy rod on the wooden stick tightly connected with the big gear, which is equivalent to the pedals on a bicycle, because the gears are too close to each other, you can't step on them with your feet, you have to shake them with your hands.

The pinion is connected to a long rod, and the two are tightly connected to form a whole. This pinion is equivalent to the wheel of a bicycle.

There are two weird huge wheels on both sides of the long pole. The wheels are made of thin bamboo poles and wide bamboo strips. Bamboo is very tough and can be bent at 70 degrees without breaking. For two, just bend it into an arc and fix it.

"Awesome!" Lin Qingxue has been helping Qin Fengyi, but after seeing the completion of this thing, Xiao Nizi was stunned, especially the enlarged version of the bamboo wheel.

"Admiration!" Han Xuening muttered to herself, "Even if I was killed, I would not be able to make such a thing."

The diameter of this wheel is about 1.5 meters. In order to make this tool play better, Qin Fengyi specially raised the height of the tool so that the wheel is 20 cm above the ground. After a while, these two bamboo wheels will rotate. This thing Mainly used for winding silk.

"Don't be in a hurry to worship, I don't know if this thing works or not, let's experiment first." Qin Fengyi broke open two silkworm cocoons, tied one end of the silkworm silk to a wooden pin on a bamboo wheel, and then put it between the gears. Sprinkle lots of shark oil in between.

Machinery needs lubricating oil, the engine of a car needs organic oil, the same goes for motorcycles, and the chain of a bicycle must also have lubricating oil, otherwise the machine will die quickly.

There is no motor oil on the desert island, but there is animal oil. The effect of shark oil is not only to heal burns, reduce inflammation and speed up wound healing, but also to lubricate.

The role of any animal oil and vegetable oil is to lubricate. When there is no engine oil, other oils can be used instead.

"Ready to start!" Qin Fengyi slowly turned the lever, and the two huge bamboo wheels began to rotate driven by the gears. The big gear rotated very slowly, because the tooth pitch was different from the size of the gear, while the small gear rotated at a different speed. It is super fast, driven by the pinion, the bamboo wheels spin extremely fast, so fast that there are no friends!
"Damn it, it's so fast!"

Lin Qingxue kept staring at the two silkworm cocoons in the golden pot. In just ten seconds, the two completed silkworm cocoons were all drawn into silk and tightly wound on the bamboo wheel.

In a few seconds, thousands of meters of silk thread were completely wrapped around the huge bamboo wheel. The structure of the bamboo wheel is very peculiar. It is divided into two with thick bamboo, and the bamboo barrier inside it Grinding with a file, the entire wheel has an arc-shaped depression, and the cocoon silk will be firmly trapped in this depression, and will not be thrown out due to too fast rotation, or entangled in the axle of the wheel.

"so amazing!"

Han Xuening looked at the cocoons on the wheel and was speechless in surprise.

"How about this, you move faster, find two thread ends as soon as possible when soaking the cocoon in the water." Qin Fengyi said, because the cocoon silk is a complete thread, and the silkworm cocoon has not yet turned into a moth to bite through the cocoon. It is a complete one and will not break during the spinning process.

"Okay! Let's try to connect first, please slow down!" Lin Qingxue and Han Xuening quickly operated, each filled a huge golden bowl with warm water, and within ten seconds of contact with warm water, the silkworm cocoons will quickly decompose. The thread ends of cocoon silk can be twisted into a thread with the thread ends on the wheel.

The cooperation of several people was quite tacit. Qin Fengyi's invention was very powerful. The three of them cooperated and the efficiency was greatly improved. In less than an hour, thousands of cocoons were drawn out.

"Next, let's weave and make some silk..." Lin Qingxue said happily, and then she seemed to see something, pointing to the sky, "There are planes..."
