After the drawings were sent, Qiao Wanshi immediately began to ask people to make parts for wind turbines and electric motors.

At this time, Qingzhu came over, because he received news that the amount of coal mined had increased dramatically, and the coal yards he opened were almost unbearable!

Qingzhu arrived in time and asked Qiao Wanshi, "What's the matter?" Have you hired workers? ”

Qiao Wanshi shrugged, "It's still those workers, but the coal has become easier to excavate." ”

She motioned for Qingzhu to look at herself, Qingzhu looked at the coal yard, those who took the chisel looked very relaxed, and if they got it casually, the coal would be broken into small pieces.

There are a lot of people carrying baskets on their backs, and the speed at which they carry them has increased significantly.

"What's the production going on?" Qingzhu asked.

"I estimate that at the current rate, there will be two or three million catties a month." Qiao Wanshi said.

Qingzhu calculated before, if there is one or two million catties, these nearby state capitals can completely eat it.

If it is more, there should be no problem, after all, more and more people are using coal.

The charcoal produced before was gradually consumed, and everyone was more willing to change to coal.

"Will it continue to increase?" Qingzhu asked again.

Qiao Wanshi shook her head, "I'm not sure about this either." Well, if production continues to increase, I'll let you know. ”

Unless something happens again, or Qiao Wanshi recruits a large number of workers, the output will not change casually.

Qingzhu came in a hurry and left in a hurry, how did he know that this was the beginning of being pitted!

Qiao Wanshi continued to tinker with her transmission belt, the wind turbine was made, and the electric motor was also made, but the problem was that the coal yard was so big that her transmission belt had to move at any time.

However, without so many wires, the wind turbine and electric motor she made could not be moved casually.

That's embarrassing.

Staring at the two things she made, Qiao Wanshi pursed her lips slightly.

The cowhide can't be too long, so the transmission belts she makes are no more than three meters each, and one transmission belt is connected to the other to transport the coal one by one.

She can't make that many motors.

The air fell into silence and Qiao Wanshi gently. Biting your fingers.

After thinking about it for a long time, she didn't come up with a way.

The system only reminded her to use the transmission belt, but nothing else.

But at least one thing is certain, the drive belt is useful.

Unable to think of a way, Qiao Wanshi walked out of the tent and walked around the coal yard.

This turn really made her figure out a way!

After returning home, Qiao Wanshi immediately began to act, removing the gears from the iron shaft in the middle of the wooden wheel, and then putting the iron shaft into an iron ring, which was connected by an iron rod, and then made a curved handle on each iron shaft, like a shelf used to draw water from a well.

If the worker turns the handle, won't he be able to drive the transmission belt to rotate?

This is the same as drawing water from a well, turning the handle, the rope is wrapped around the log, and the water is lifted.

Now Qiao Wanshi replaced the rope with cowhide, the cowhide wrapped the log to form a closed circle, and then put the entire water pumping equipment horizontally, after the coal was shoveled onto the cowhide, turn the handle, the cowhide turned, and the coal was carried forward?

The bracket is made slightly inclined, high in front and low in the back, and the coal will not slide down at a small inclination angle.

After it is done, it is taken to the coal yard to test, and the workers carefully pour the coal in the basket on the cowhide, and the four people hold the handle together and turn it, and the coal really moves forward with the cowhide.

The faster you turn, the faster you move.

Another belt is taken and the first belt is handed over.

The first belt is high, the second belt is low, and the coal on it falls right on the cowhide of the second belt.

The coal then moves forward on the second belt, with the tail end higher than the front end, just as the low end of the third belt can be placed below the high end of the second belt.

Several transmission belts were connected, and a long line of more than ten meters was immediately picked up.

A basket of coal was poured on the first transmission belt, and with the continuous rotation of the handle, the coal was transmitted more than ten meters away in a short time.

"Isn't that easier than carrying coal?" Qiao Wanshi asked?

The workers scratched their heads, this distance is still very close, so the effect is not visible for the time being.

All the transmission belts made by Qiao Wanshi were changed in the new way, and then a long line was laid in the coal yard, all the way up the slope to the front of the coal pile.

"Today, everyone is digging around here, and after digging in this vicinity, we will change places and the transmission belt will follow." Qiao Wanshi said.

In this way, the distance of workers carrying coal is maximized.

The types of work done by the workers were tested and adjusted, and finally came up with the most labor-saving method, that is, along the entire transmission belt, that is, the coal within a few meters on both sides of the transmission belt was dug up and sent to the transmission belt.

The transmission belt keeps moving forward, and the coal is constantly being transported to the coal pile.

Workers no longer have to carry coal over long distances, and spend more time digging coal, which is definitely more efficient.

Qiao Wanshi's change has doubled coal production!

Now the monthly production capacity is about five million catties per month.

The number of workers was still the first 100 workers, but the output was increased tenfold.

Originally, the labor cost per catty of coal was about 1.25 yuan, but now the cost per kilogram of coal has been reduced to 0.125 yuan, which is low.

Facts have proved that no matter what, as long as you are willing to use your brains and think of a way, you can save labor and costs.

Of course, this is also inseparable from Qiao Wanshi's system.

If it weren't for the blasting bombs that the system gave her, she wouldn't have been able to kill her at the current speed.

At this speed, it is natural to recruit Qingzhu back.

Qingzhu began to faintly feel that he was really cheated by Qiao Wanshi, although he still hasn't figured out where he was cheated.

This time, Qiao Wanshi's mining speed doubled, and Qingzhu had to expand the scope of sales, he tried to choose the nearest state capital to minimize the freight, but it was inevitable that there would be farther places, because the nearby places could no longer eat so much coal.

In some places, the shipping cost has reached two cents.

Originally, Qiao Wanshi only left Qingzhu with a profit of three pennies of coal, and when the transportation cost was lost by two cents, he only had one penny left.

Despite this, most of them can earn two cents.

The sales volume increased tenfold, and Qingzhu's profit did not increase tenfold, but it also increased to seven times.

If this continues, Qingzhu will be able to earn seven thousand taels of silver every month!

This was unexpected by Qing Zhu.

So being cheated or something, is it his delusion?
