I went ashore by weaving straw shoes and became a master craftsman

"Just turn it?" Mrs. Zou asked, after confirming that she was not blowing with her mouth, she turned the windmill clockwise according to Wang Ge's finger.

The vertical windmill, the vertical shaft, and the horizontal wheel are firmly wedged to each other, which is equivalent to one body, so the horizontal wheel also rotates clockwise.

The installation position of the vertical wheel is below the right side of the horizontal wheel, and the spokes are staggered and occluded.Thus, along with the clockwise rotation of the horizontal wheel, the vertical wheel rotates backward.

Equally, because the wedging of the horizontal shaft is very tight, the horizontal shaft naturally follows the vertical wheel and rolls backwards round and round.The stone pendant at the right end to maintain balance is subjected to friction, and is lifted up and down, lifted up and down, and securely balances the weight of the wooden vertical wheel at the left end.

In short, it took Wang Ge half a day to chisel these components, and it only took a few breaths for Mrs. Zou to drive them, so the latter was at a loss, wondering what is the use of these wheels and shafts for Wang Ge?
Wang Ge: "Sister, dial back again."

Turn the windmill counterclockwise, and the vertical wooden wheel on the lower right will drive the horizontal shaft to roll forward.

Wang Ge pointed to the stone pendant and said, "Imagine, sister, what if the stones were replaced with the sprocket of the overturned car? The sprocket on the shore."

Rocks, overturned cars... sprockets on shore?Mrs. Zou couldn't imagine it.

Interlacing is like a mountain.Wang Ge could only draw the image of the overturned car under the stone pendant, explaining little by little with gestures with both hands: "Sister uses the windmill on the left as a crank handle, or pedal wheels. Can it be turned to wipe the water? But when you turn the windmill, is it equivalent to hand cranking and pedaling? At the end on the right, where the overturned car is, is it being driven to turn like this, blowing the water in the canal to the shore?"

"Huh? Yes!" Mrs. Zou was delighted and finally understood.

"The second time you turned the windmill, did it turn in the opposite direction? Could it blow the water accumulated on the bank into the ditch?"

"Yes! Yes, that's right!"

"Sister, look back to the left. Think, if the windmill is strong enough, and the wind is strong enough to turn the windmill, is it not necessary for sister to turn the windmill? Does that mean that the overturned car on the right leaves sister, as long as With enough wind, water can also be diverted for irrigation, and it can also be reversed to drain waterlogging?"

Mrs. Zou blinked her eyes, looked carefully at the windmill, at the interlaced spokes of the two wooden wheels, at the vertical axis and horizontal axis, at the stone pendant, and at the overturned cart painted.She turned the windmill slowly again, and then reversed.

stop.

At this moment, everything looks different from before.She looked at Wang Ge again, with tears in her eyes.

Wang Ge continued according to his own thinking: "If this method is feasible, I think it can be used not only for overturning cars, but also for grinding! Use the force of wind to push the mill. In that case, the cold winter wind is strong, bringing It’s not all suffering for farmers.”

Mrs. Zou nodded her head vigorously, and replied with a sob: "Yes, the stronger the winter wind, the faster the windmill turns, and it can easily grind for others. Age, why do you think so, and are so capable!"

A small windmill, I didn’t expect it to be connected with the overturned car, Age, you are really Liaodong, no, you are the lucky star of all farmers!

"You can't just rely on the wind." Wang Ge changed the subject, and drew a horizontal wheel with the vertical axis as the center at the position where the bottom of the windmill plunged into the soil. Take a wooden plank from the side basket and block the windmill. "Now we don't have any windmills. When the water rushes towards the wheel I drew, will the wheel turn? Does the vertical axis follow? Does the horizontal wheel on the axis also turn?"

"Ah...it's back to the way it was just now!"

Wang Ge put down the plank: "Yes. Use the impact force of the canal water to replace pedals and hand cranks." She swiped her finger to the rightmost position of the overturned car, "finally returned to the canal water. With this improvement, only the main chain of the overturned car When the wheel is on the shore, the requirements for wood are higher.” The wood of the horizontal wheel that is horizontal in the water must not only withstand long-term immersion, but also resist the impact of rapid water and stones.

Mrs. Zou came up with an idea: "Keep the windmill too. The wind blows and the water rushes, and the speed is faster... no," she said amused herself, "If the wind is in the opposite direction to the water flow, the wooden wheels will not be able to turn. Moved."

"That's right. So there is a third improvement method. Where there is no wind or no canals, animal power can be used instead of pedals and hand cranks. I will continue to work."

"you eat first."

"Eat after work."

Wang Ge didn't know that her three improvement methods were called by later generations: wind-turned overturned cart, water-turned overturned cart, and ox-turned overturned cart.

The latter two appeared in the Song Dynasty, while the record of wind turning overturned carts was even later, appearing for the first time in the "Nongzheng Quanshu" written by Xu Guangqi in the Ming Dynasty.

The three improvement methods go hand in hand, and the promotion of farm tools and machinery according to local conditions corresponds to a passage recorded in "Kao Gong Ji" spoken by Meng Nvli when she first entered the emergency training camp.

The sky has its time, the earth has spirit, the materials have beauty, and the workmanship has ingenuity. If these four things are combined, then it can be good.

At that time, the prospective craftsmen only needed to achieve "skillful workmanship". Now Wang Ge has finally reached the realm of considering "the sky has its time and the earth has its spirit".

At the time of Shenzheng, Wang Ge was accompanied by Mrs. Zou to make meritorious service. The models, molds, and stone pendants of the three types of overturned cars were all handed over to Wang Shuzuo.

The mod still lacks rollovers, but that's irrelevant.In addition, in order to make the windmill rotate more freely, she added a casing (chiseled with arrow bamboo) to the vertical shaft. Just insert the casing into the mud to make the windmill easy to move.

Wang Biao frowned as he looked at the drawings one by one.Who would have thought that on such an ordinary day, the application of overturned cars has undergone tremendous changes!It's okay to use water power and animal power, but how could Wang Ge think of using the power of wind?

And no matter how you change it, the principle is always that the horizontal wheels and the vertical wheels are interlaced, it's that simple? !

Craftsmanship!A born wonder craftsman!

The three improvements are not trivial, and they must be reported to Dongyi Mansion urgently.Also, to send someone to inform Cao Shi of meritorious service, Mrs. Duan has to come back early.

The floor of the house was covered with pottery bricks, and it was impossible to insert the molds. Wang Biaozhi and Wang Ge came out. He asked Mrs. Zou to find Gongcao's officers and officials. Turn over the car and water turn over the car together.

There is no need to fight for the ox turnover, because its principle is the same as that of the water turnover, except that the horizontal wheels in the water are not needed. Instead, a straight wood is tied to the vertical axis, which is equivalent to a shaft, and it is enough to put on the ox to pull the circle.

"Look at the model first, and then the model." Wang Biaozhi told these officials, and then asked Wang Ge alone: ​​"This time the credit will not be small, and you can still exchange it for the first place in the county?"

"Yes. If you finish the exam one day earlier, you can go home one day earlier."

Wang Biaozhi nodded lightly: "The frontier county is poor, and there are no people left. Don't look at the craftsmen and masters, how many people would like to stay in Liaodong forever."

How do you answer this?Wang Ge bowed her head, at this time she dare not say that she is not thinking that the life in Bian County is hard, but that she is worried about the elderly in the family, what if the other party promises to bring her family to Xiangping City?
"Actually, you can go home by sea boat to Donglai County, and then go overland. Donglai County belongs to Qingzhou, which is not far from Yangzhou."

There is no free meat pie in the world, Wang Ge still lowered his head, waiting for the next article.
