Chapter 47 Crack! Take Four Drawings In One Go!

before.

The time is not ripe enough, Qin has no reliable iron to use.

now.

Accompanied by the emergence of low carbon iron.

Zhao Ze can bring out many things.

For example, columbine carts and curved plows.

then.

Zhao Ze stood up, patted his butt, and led them to the construction yard.

See the appearance of Zhao Ze.

All the craftsmen gathered around to greet the God of Wealth for a long time.

Snapped!

Zhao Ze took a sketch.

"This is a curved sickle!"

In fact, the Warring States already had a sickle.

but.

Because they don't understand the principles of mechanics, the sickles made by the craftsmen at this time are all straight sickles.

look.

It's like a ruler.

And this straight-forward structure is easier to build and simple in workmanship.

Artisans also enjoy making sickles.

This sketch taken by Zhao Ze is a curved sickle.

It's just that the blade is slightly bent inward.

But the effect.

But it has increased by at least three times!

"Curved sickle?"

The craftsmen watched curiously.

It looks like a straight sickle, not much difference!

It's just a slight arc!

Snapped!

Zhao Ze took another drawing.

"This is a chainsaw!"

Actually.

Saws have long been invented.

The inventor is Lu Ban, the craftsman originator of Lu State.

It is said.

When Lu Ban went up the mountain, his legs were cut by a kind of grass.

He picked off the leaves of the grass and found that the edges of the leaves had jagged teeth, which was the reason why it could cut through human skin with its tender body.

So Lu Ban rushed home.

Immediately imitate the leaves and make sawtooth.

But it is well known.

In this era, bronzes are too soft and not hard enough to be used for sawtooth cutting, which is difficult to achieve.

And ironware?

High carbon content, very fragile.

Saw a stick, the stick was sawed, and the saw was broken.

so.

Craftsmen don't like to use a chainsaw.

The efficiency is too low.

It's not as practical as using an ax for the big ones and a carving knife for the small ones.

Now Qin has low-carbon iron.

The hardness and toughness are sufficient, and the iron saw can be promoted.

"A chainsaw?"

The craftsmen were stunned.

Didn't this thing already exist?

"It's not the same, look at the sawtooth."

"My serrations are straight on one side and beveled on the other, so it's effortless to use."

Zhao Ze explained.

The sawtooth at this time is also because I don't understand mechanics.

Therefore, the sawtooth is made with oblique sides.

The saw teeth look like acute triangles, while Zhao Ze uses modern saw teeth that look like right triangles.

It saves effort when used.

And the cutting effect is also better.

Snapped!

Before the artisans reacted.

Zhao Ze also photographed Quyuanli's straw paper.

"This is Quyuanli!"

same.

Farm tools such as the plow have long existed.

But everyone used the straight shaft plow, and what Zhao Ze took out was the improved Quyuan plow.

Quyuan plow is equipped with a freely rotating plow disc on the shaft head, which can make the overall plow frame smaller and lighter, and it is also easy to turn around and turn, and the operation is more flexible.

Can save a lot of manpower and livestock.

It is much inferior to the steel giant cultivator, but the Quyuanli that appeared in the Tang Dynasty was absolutely explosive in the Warring States Period!

Haven't waited for the artisans to study.

Snapped!

Zhao Ze took another sketch.

"This is a car!"

The columbine car was born in the Western Han Dynasty.

That is, the Western Han Dynasty that destroyed the Qin State and established the Han Dynasty.

It is still a hundred years away from the appearance of the columbine car.

But Zhao Ze doesn't mind letting the car appear in this world ahead of schedule.

the people now.

Bend over when sowing.

Remove the soil and sprinkle in the wheat seeds.

Cover the soil.

Press firmly.

But with the columbine car.

When sowing, you only need to use an ox to pull the columbine cart, and the columbine feet can ditch and sow on the flat land, and at the same time cover and suppress it. acre".

until the age of technology.

Columbine carts are also used in some remote mountainous areas.

It can be seen how practical it is!

Four drawings in a row.

The craftsmen of the factory were overwhelmed.

They didn't even understand the curved sickle, but Zhao Ze took out the chainsaw, the curved plow and the cart again!

Each drawing is enough for them to study for several days.

"My eldest son, how long do you want us to make these things?"

A craftsman asked embarrassingly.

"Three days, no more."

Zhao Ze pondered.

It's just a sample. It's definitely not difficult for these dozen people to add up.
