It is noon when the sun is at its peak. The strong sun makes the skin hot, and the sea breeze blows, which does not make people feel hot.

The summer in Kaohsiung is so hot, but the weather is not too hot. Jiang Zhiang wiped the sweat from his head, looked at the large copper pot being hoisted, and the soldiers holding the copper pot with their hands around. Their bodies were almost wet. In order to lift the large copper pot weighing more than 800 kilograms onto the stove, they had to use a triangle bracket and pulley set. Several people held the copper pot, while several others pulled the rope hard, trying to hoist the large copper pot onto the stove.

"One, two, three, come again!"

Fang Dengyue shouted loudly from the side, and the two groups of people who were pulling the ropes and the iron pot cooperated to lift each other, but it was obvious that Fang Dengyue's command was very bad. It took a lot of effort to command the group of soldiers to stack the big copper pot on the stove. Fang Dengyue shouted for a while. Under his command, he moved left and right, and finally placed the big copper pot in the right position.

After the big copper pot was successfully in place, Fang Dengyue felt very accomplished. While wiping sweat, he said to Jiang Zhiang:

"Brother Jiang, I finally put this big copper pot in my arms. Everything is ready. I just wait for the fire to start construction."

Jiang Zhiang smiled. Some people call this copper steam boiler a big copper pot, but Fang Dengyue called it a big copper pot. In fact, it looks like a huge copper pot.

Since Jiang Zhiang became a teacher, he has been instilled with some new concepts by Mao Geng. Mr. Mao has his own shipbuilding scripture, citing Mr. Mao, for example, it is not difficult to build a hull, but the difficult thing is to build a fast and good sea boat, and it is difficult to build a fast sailing boat that runs against the wind. However, the best ship is not a sailing boat, but a steam-powered boat. And so on.

What kind of steam-powered ship is a steam-powered ship? Is it really like the story made by Chen Liang, that you can sail in the sea without sails? At the beginning, Jiang Zhiang was full of questions. However, when Jiang Zhiang and Tan Xiaochun and Yi Bojun talked with each other and listened to Mao Geng teaching the principle of steam power, he became a little enlightened. In particular, Jiang Zhiang saw the magical demonstration of the steam-power model with his own eyes, and then Jiang Zhiang was fascinated by steam power.

In the laboratory of the technology office, there is a model of steam driving the impeller to rotate, but it is just a small copper pot. Well, Mr. Mao called it a miniature steam boiler. He burns the fire under the small copper pot. Soon after, a copper tube extending above the copper pot will emit steam. Wait for a while, the hissing stream of steam will push the small impeller to rotate. Wow, it's really wonderful! But when I look back, I think about it, it's actually the same as the turbulent water flow pushing the water wheel to rotate.

But it was just a small impeller. On the other hand, the impeller that Tan Xiaochun and Yi Bo were instructing people to install was a big guy. This huge impeller also had to drive the alligator crusher - it could be called a pile of iron lumps covered with iron. Can the steam emitted from this big copper pot work?

Speaking of which, Fang Dengyue was involved in the Taiwan conquest team this time. After occupying Taiwan, the court fulfilled its previous promise. Fang Dengyue was thus awarded the position of the director and immediately reached the eighth rank. For Fang Dengyue, who was ignorant, it was already hard to expect to be promoted to the eighth rank. Just imagine, Lu Jiuyuan was as profound as Lu and had only been promoted to the eighth rank. The Fang family boy was already the eighth rank under twenty. Well, with an official position, he had to be assigned a dispatch. The cement workshop needed to send an official management team, so Fang Dengyue took the opportunity to become the temporary manager representing the official - the deputy manager, but there was more than one deputy manager, and Fang Dengyue was one of them.

Jiang Zhiang couldn't help laughing when he heard Fang Dengyue's seemingly fooling around and almost burst into laughter.

Fang Dengyue said that when he was excited, he seemed to have forgotten something, so he turned to ask Jiang Zhiang:

"Brother Jiang, that iron guy is called a crocodile---the crocodile-type stone crusher, right?"

"Soteric crusher, Mr. Mao said."

"Yes! A crocodile-like alligator crusher."

Jiang Zhiang could no longer bear Fang Dengyue's shocking show, so he had to go directly to see the installation of the impeller and alligator crusher.

The next day, a high-level curious person came to the scene. This curious person was Han Tuozhou. Han Tuozhou obviously knew less than Yan Xiaojiang.

The sun was still hot. Although the copper boiler was hoisted after the hoisting was completed, Jiang Zhiang stood in the shed with Han Tuozhou at this moment, feeling that it was three more hotter than yesterday, so he had to apply sweat on his head from time to time. The fire in the big stove under the copper boiler was burning vigorously, and the air in the entire shed was so hot that it was hard to bear.

Han Tuozhou was also sweating, but all his attention was focused on the steam power that was so wonderfully praised by Jiang Zhiang, and he was completely unaware of the heat.

Someone shouted, "It's turned, it's started to turn!" Sure enough, the two big wheels began to slowly start, slowly began to accelerate, and quickly turned rapidly.

"Why doesn't that crusher move?"

Han Tuozhou thought something was wrong with the agency, so he questioned it on the spot.

"Sir, this is the case. Those two friction discs must first be turned to the high speed before they can operate the mechanism and drive the crusher."

The alligator crusher designed by Mao Geng is different from the ones in later generations. Of course, there is no difference in principle, but the design principle of the later spiral press is copied in power transmission. It can be said that this jaw crusher combines the advantages of the alligator crusher and the spiral press. The friction disc transmission can avoid overload damage, and the biggest advantage of the spiral transmission is that it has a power amplification effect. The transmission of power is in turn: steam drives the impeller to rotate, and the impeller power is conveyed to drive the two friction discs to rotate. Under the action of friction, the friction disc drives the flywheel forward and reverse, and the screw is connected to the flywheel, thereby advancing and retreating, and reciprocating.

As soon as Jiang Zhiang finished speaking, the crusher took action.

In an instant, this mechanism completed the power transmission based on friction transmission. When the mechanism was closed, the friction disc on the left was leaning against the flywheel. Due to the friction force, the flywheel with bristles covered with bristles began to rotate forward, pushing the screw forward, and the hinge at the front end of the screw connected to the four-link mechanism. The screw forward drives the four-link mechanism, thereby pushing the two open iron plates of the alligator crusher to choke. These two powerful iron plates are carved on the iron plate. These neat through grooves are like rows of iron teeth. The stones entering the iron plate are crushed in an instant.

During return journey, the left friction disc is disengaged, and the right friction disc is against the flywheel. The flywheel and the side friction disc are frictional to obtain the reverse power, and the screw reverses, thereby completing the return journey and pulling open the two iron plates that are entrapped.

As they were dazzled by everyone, the iron plates opened and closed, and the stones continued to enter the crocodile crusher, crushed, dropped, crushed and then fell. This crocodile crusher was simply a giant beast that swallowed stones. The stones were swallowed by it, digested into gravel and discharged. In comparison, the ability of the water mill to crush the stone was simply weak.

"Compared with this, the water mill is just a slag!"
