Dinghai Port, Shipbuilding House.

A thirty-meter-long centipede boat was dragged to the shore, and Chai Lin only lifted the cover of the pot cage.

Yu Hao, the director of the shipbuilding workshop, is still covered in confusion, and I don’t know what kind of machine this is.

"Supervisor Yu, let's put a pot and a cane machine at the tail of the centipede ship." Chai Lin said.

Yu Hao said: "This big guy must weigh 700 to 800 pounds, what's the point of doing?"

"This is not a big guy, this is a little guy. If it is filled with water, it weighs a thousand pounds. This is called a pot cage machine, which consists of a boiler and a steam engine. The steam engine rotates and drives the propeller to drive the ship to sail rapidly." Chai Lin introduced.

When Yu Hao saw that the propeller was 100 centimeters in diameter, weighed more than 100 kilograms, and was made of stainless steel.

Although there are ready-made pot cuckoo machines, drive shafts, and propellers, it is still very difficult to install on the ship.

The harbor's man-powered wooden frame hand-pulled hoist gantry crane, and a pot carrying machine with a capacity of more than 1,000 kilograms was hung on a pulley, and then slowly placed it at the end of the centipede ship's warehouse.

The cabin plate felt not thick, and Yu Hao was worried that the machine would be broken by bumps, so he asked the workers to find a wooden board and then put a layer of wooden board under it.

Yu Hao planned to let the workers hang the machine through the gantry crane. Who knew that Dian Zhengnan said: "There is no such trouble. I will carry it a little together, just a little bit of it."

As he said that, Dian Zhengnan actually lifted the pot maker weighing thousands of pounds, making the craftsmen dazed.

The craftsmen first fixed the wooden boards to the bottom of the ship's cabin, and then fixed the pot and camel machine to the wooden boards. When they built many details, they didn't expect that they all needed improvements now. Chai Lin took the notebook one by one to write down the marine steam engines. There are still many different places.

The old method is the same as the steam engine flywheel transmits its ability to the propeller's transmission shaft through the belt connection, and the transmission shaft drives the propeller. This is only a temporary method. It is more reliable to use shaft transmission for high-strength operation of propellers, and belt transmission obviously messes things up.

The problem now is the sealing problem at the drive shaft opening from the stern opening, so the ship cannot be allowed to leak water.

When designing, Chai Lin considered it quite comprehensively. The outside of the transmission shaft was a layer of steel pipe. When it was rotated, the inner shaft rotated, and the outer steel pipe did not rotate. The carpenter opened the hole to install it, and it didn't take long to install the propeller.

I don’t feel the time to work, and it’s been dark for a long time after the installation.

Chai Lin brought a pot-camel operator from Tiangong Second Battalion and arranged for him to burn the boiler and slowly burn it, so that it would start tomorrow.

In fact, it is still time-consuming to boil from cold water. After all, although the boiler is not big, it still has about 500 kilograms of water.

The operator slept in the cabin, which was very convenient to add a coal management boiler at night.

I was speechless all night, and the next day everyone came to the cabin and felt very warm.

Chai Lin pulled the steam pressure reducing valve, and the whimpering steam spurted out, scaring everyone.

Chai Lin said to the pot cuckoo machine operator: "Prepare to start the experiment."

"OK."

The operator pulled down the steam valve, and the steam engine began to rotate slowly. After more than ten seconds, the flywheel rotated rapidly, and the transmission shaft rotated rapidly under the belt.

The person outside who was in charge of observing the propeller shouted: "It's turned, it's turned, it's turned very fast."

When Yu Hao saw that there was a little trouble at the opening of the stern of the boat. Due to the vibration, the sealing waterproofing he made yesterday actually had tiny cracks. Water leakage is not a joke on the sea.

"The owner of the manor, I have stopped the pot and camel machine. I need to find a way to re-reinforce the waterproofing at the opening," said Yu Hao.

Chai Lin also saw that since it was renovated from an old ship, there must be many inappropriate places.

"Okay, think of more ways, and let's go to the port to test in the afternoon," Chai Lin said.

The dozen craftsmen Yu Hao led did not know much about scientific theories, but they could solve problems and had strong practical hands-on skills. After a while, they proposed five or six solutions.

When Yu Hao was busy, Chai Lin came to the iron mine.

More than 3,000 miners from Qingzhou live in the ground nest and eat in tents.

Dian Zhengnan and Jie Bao were both shocked. They saw that the huge mine were full of people wearing rattan helmets. The mine was divided into two parts, and the south part was hired miners. A team of hundreds of people were set up, a team flag was set up, and a team leader was set up, and a team leader was set up. Thirty teams were gathered in the south, and iron rods, pickaxes, and sledgehammers were used to dig iron ore, and then crushed them with a sledgehammer. The team leader, the team leader, was both a worker and a supervisor, and on the one hand, kept keeping the speed and quality of work, and on the other hand, reminded to pay attention to safety. Work in the mines were stones, and safety was very important.

Everyone wore rattan hats lined with fur, which was warm and protective. The miner responsible for crushing was covered with several layers of gauze on his mouth and nose, which was set to prevent dust from entering his mouth.

The sources of these 3,000 people are quite complicated. Some are local miners, some are recruited from Dengzhou, and more are refugees recruited from Qingzhou. When these refugees came, each of them sent 100 kilograms of food in advance, which can be regarded as solving the food problem of their families.

Hesitation has been raining and snowing recently, and Shi Xiu has stopped recruiting people. Variety Literature

Wang Hong, as the introducer who recruits the most personnel, is now Zhang Han’s deputy on the construction site, responsible for coordinating the dispatch of personnel from each team, etc.

Wang Hong looked up and was surprised to find that he had met Chai Lin. He hurriedly bowed and said, "Mr. Chai, you are here."

"Well, I'll see how the workers live and work." Chai Lin said.

Wang Hong said: "Ten people live in a garden, which is not cold, and the conditions are pretty good. The work is relatively easy. It rains and snows, and most of the workers have rested, and only the workers working under the shed are still working."

"How is it eating?" Chai Lin asked.

"Breakfast rice porridge, pickled pancakes, lunch usually consists of bone stews and pancakes, and dinner is basically the same. Sometimes bundles of green onions are shipped, and some seafood is much better than home. You have to count the pickled vegetables in your hometown." Wang Hong said.

A miner saw Chai Lin while working, suddenly stopped, threw away the sledgehammer in his hand and knelt in front of Chai Lin.

"Thank you for your life-saving kindness." After that, kowtowed to Chai Lin.

Chai Lin didn't know what happened, so he quickly pulled the person up. The miner was not young, almost fifty years old.

"What's the matter? You don't need to give this great gift when you get up and talk." Chai Lin said.

Wang Hong said: "Master Chai may not remember it. This is the miner I introduced on the first day, from our village."

The man said, "My grandson is almost dead when he is hungry. He has lost more money and received a hundred kilograms of sorghum rice from Lord Chai to survive. So I have to thank Lord Chai."

Many miners saw that it was Chai Lin and saluted them one after another.

Chai Lin said at the top of his voice: "Come here today to see how our miners live, whether we can sleep well, and whether we can eat enough."

A miner shouted, "Life is so good. I haven't bought new clothes at home for three years. Before I even started working, I first sent out a new set of clothes, new shoes, and new hats."

Some also said: "It's better than we thought. I thought it would be good to have pancakes and green onions. Who knew there were pickles, rice porridge, bone stews, and occasionally seafood. Life was great."
