It starts with the production team driving the big truck

Chapter 476 The big waterwheel turns slowly...

All the strong laborers in the village came, and the saws they bought when they went to the mountains to plant trees last year were all taken out from the warehouse. After filing the saw teeth with a file, the three people divided into groups and began to break the wood.

Sun Jianping got a good job, using a plane to polish the surface of the wood!
He held a polished planer and pulled it over the wooden board that had been broken by sawing. He placed it on two long benches. He held the planer tightly with both hands and pushed it forward gently. The sharp blade under the planer easily cut it. A layer of wood is scraped off, revealing smooth and fine texture.

Carpenter Hao held a cigarette in his mouth and brought over the planed wood. He held a ruler and clicked, jingled, axed, sawed and chiseled according to the dimensions on the drawing. After a while, there were many large and small ones on the ground. board.

Children in the village who had not yet gone to school rushed in, picked up wooden boards and piled blocks to play.

Everything else is easy to make, but the axis of the waterwheel is the most difficult of all parts and has the most stringent accuracy requirements!
But for the senior carpenter in front of me, that was nothing!
Carpenter Hao patted the ash wood cut into squares, found a few pieces of wood from the wooden box, simply spliced ​​them together, and put on a belt, it was a simple turning machine!
Sun Jianping looked at this simple turning machine with curiosity. At first glance, the structure was shockingly simple!

but……

Carpenter Hao fixed the ash wood to the turning machine. He held the sharp turning knife in one hand and stepped on the pedal below. The wood began to rotate hummingly. When the sharp turning knife was pressed against it, pieces of fine sawdust fell across the ground. It flew out like falling snowflakes, and soon a layer fell on the ground.

Looking at the spun wood again, it had changed from the original four corners to a round one, as long as a palm and as thick as a rolling pin. Carpenter Hao frowned, grabbed a handful of sawdust and pressed it on the wood, and turned the turning machine again. The burrs on the wood surface were quickly polished!

Then polish it with cowhide. The "shaft" is about the size of a palm, slightly thicker in the middle and tapered at both ends. The surface is as smooth as a mirror surface!
Carpenter Hao followed the same pattern and made more than thirty more. They stood on the bench one by one, in a row, and measured them with a ruler. They found that the sizes were exactly the same!

This is the craftsmanship of an old carpenter!

"The iron bearings sold by the supply and marketing cooperative are not good. They will become rotten after a few years of use. It will be very laborious to dismantle and reinstall them. We will have to use the good things left by our ancestors!"

Carpenter Hao took a piece of ash wood that had been prepared long ago and was as thick as an enamel basin. He also screwed the surface until it was smooth and discernible, then used a chisel to cut out grooves. After polishing them smooth, he took them out and screwed them in place. The wooden bearings were put in one by one, and they fit perfectly. When I fiddled with them with my fingers, they started to rotate smoothly!

"It's just an axle, you're a piece of cake!" Zhang Ziyi came over, slapped Hao Carpenter on the back of the head, and laughed.

Carpenter Hao was not upset and continued to use the chisel to carve out the groove for the bearing. After a while, the entire shaft was ready. He picked up the ruler and measured it. He lowered his head and thought about it, then patted the water-saving curved willow ball. Wood, "How do you adjust the shaft in the middle? I'm afraid it won't be able to hold it if it's made of wood. Why don't I twist my eye and push an iron rod in?"

"Let's use iron!"

"Okay, see if you guys have any iron shafts here and find me one. I'll turn it according to the size..."

Sun Jianping put down the plane and went to Lao Chengtou to rummage through the cabinets to find the parts removed from the Little Devil's car. Finally, he found two iron rods as thick as rolling pins and brought them over.

After a lot of work, the basic structure of the waterwheel has been roughly completed. Everyone worked together to install the waterwheel. Carpenter Hao held his pipe in his mouth and walked several times around the waterwheel that had begun to take shape. He frowned and picked up his pencil. Paint some parts and then have the waterwheel dismantled and renovated.

As for the base for placing the waterwheel, since this year was the "Wukai River", the river surface was very dangerous. Sun Jianping thought of a way to place the waterwheel on a relatively hard ground five meters away from the river, and used more than ten kilograms of gunpowder to melt the frozen waterwheel. The ground is blasted, a base prepared with cement is put in, and concrete mixed with warm water is poured in, waiting for the base to harden.

Carpenter Hao started manufacturing the second waterwheel non-stop.

Sun Jianping was worrying about a newly bought small motor.

How should this thing be placed on a water tanker and be driven by water flow to generate electricity?
"No, no, no!"

After hearing his idea of ​​setting up a motor as a spindle on the waterwheel to drive power generation, Carpenter Hao shook his head like garlic, "The waterwheel is all made of wood, and it weighs thousands of pounds when soaked with water. This gadget can withstand Can you survive? You have to crush it to pieces!"

"That……"

"Think of other tricks!" Carpenter Hao patted him on the shoulder to encourage him.

Sun Jianping ran to the river with the motor in his arms. He put the motor into the cold and biting river water, shook his head, and wondered if adding two paddles to the motor would make it spin.

No, once the motor gets wet, it will rot very quickly. Don’t let this thing get wet!
As for the wires…

Sun Jianping changed several methods, and suddenly slapped his thigh, and there it was!

Put the motor on a shelf, put it on a long main shaft, and install propeller blades under the main shaft. In this way, the motor will rotate with the impact of the water flow. Doesn't it mean there is electricity?

I'm really smart!
Sun Jianping was so excited that he immediately drew a drawing and handed it to Carpenter Hao. Carpenter Hao took it, looked at it, and nodded with a smile. This kid has so many things in his mind!

Okay, just do him this favor!
For Carpenter Hao, this is just a piece of cake, but because this year is the Wukai River, there are so many floating ice on the river that it almost blocks the river channel. If this simple motor is put down now, it will probably be crushed by the floating ice in a short time. Got it!

Let’s worry about the water tanker first!

It only took Carpenter Hao three days to build the two waterwheels. As the temperature rose, the ice floes on the river gradually melted and the water flow gradually stabilized.

In Ermajia Village, horse-drawn carriages pulling wooden planks, wooden frames and other items came to the river in a mighty manner. Everyone started working together and began to follow Sun Jianping's instructions to place the water tanker on the fixed cement piles.

Carpenter Hao held a cigarette in his mouth, squinting his eyes as he watched the boards being spliced ​​piece by piece, and inadvertently sniffed.

Soon the waterwheel took shape. A huge flywheel stood by the river, more than four meters high, with thirty-six water buckets placed on it. As long as the ground thawed, water could be drawn from the Gulu River. Then open a small channel a few meters long to guide the water under the waterwheel, and rely on the current to push the waterwheel to rotate and lift the water.

The folks in Xiaoxishan stood on tiptoe and watched them doing something strange.

The guys in Ermajia are really capable of doing things!
"Good stuff!"

Team leader Luo Shihong came over and watched with curiosity as they set up two water trucks by the river. She waved to Old Cao and handed him a cigarette, "Party Secretary Cao, what are you..."

"Ah, isn't this? This year, we are thinking of clearing out the saline-alkali land on the high hills and downhill slopes to grow rice, and use this thing to lift water into the fields!"

"Is this... okay?"

Luo Shihong looked puzzled, and even felt that they were taking off their pants and farting - unnecessary!
Just get a water pump and throw it into the river, then turn on the electricity and it will be fine!

He immediately rejected his stupid idea!
电？
Where can I get electricity?
Now even the Taipingshan Brigade Headquarters doesn’t have power!

"Can you give it a try? It won't match anything." Lao Cao smiled heartily, lit the cigarette and took a puff, "It smells good, red plum?"

The two huge waterwheels were finally installed in place. From a distance, they looked like two ferocious giants standing by the river. Qian Huijun lowered his voice, "Brother, I suddenly thought of Don Quixote! If he comes to us This will probably challenge these two giants!"

"Then I'll push his head into the water and let him calm down."

Sun Jianping chuckled!
