Eagle Byzantium

Then the group of people came to the Persian-style windmill on the edge of the college mountain. The widow among them had her and her carriage parked in the shade at the foot of the mountain because she was tired.

Outside this forest is a field that has just begun to revive. Gawain's Seleucid civilian army destroyed it during the previous siege. Now a German immigrant group, about 1,200 people, has taken over this area. The blond The widow half-opened her eyes, lying lazily on the cushions of the shoulder cart, looking at the white birds flying in the fields and woods, and the busy figures of the immigrants: they were repairing the burned houses and starting to cut them off. Replant crops in empty ridges.

"Hmph, that's fine. This widow is so happy and curious about everything she sees, and even applauds. It's so embarrassing!" Anna thought as she climbed the stairs toward the top of the mountain.

As a result, it didn't take long for the group to see the model of the Persian windmill, which was detailed but minute.

This kind of windmill is also called "Sistan Windmill", which comes from the place where it was invented, because Sistan in Persia is adjacent to only a salt lake. Apart from the palm trees, it is an endless mountainous desert. The violent wind rolls up the sand. Residential areas can be submerged in a very short time, so the locals can only rely on themselves by learning the two technologies of sand control fences and "prayer wheels" from the distant empire (China), the latter of which is the "prayer wheel" It's the windmill.

The wind on the mountain was very strong and empty. Anna and the Archon, with their dancing hair, saw: the small sunfish and the model of the Persian windmill erected by the pirates. It was only ten Anna feet tall (about two feet tall). A solitary small tower (about Anna's height). The tower is divided into two floors. The upper part is a raised semicircle, and the lower part is a cylindrical shape that is narrow at the top and wide at the bottom.

This evil shape made Anna and Cabernet blush at the same time.

"Well, but what about the windmill?" Anna coughed twice to cover up her embarrassment.

"The sailcloth of this windmill is hidden inside the tower." Little Agnes introduced, and then everyone heard the roaring sound coming from the small tower, and then they learned that there was indeed a mystery inside. . "The secret lies in the air hole in the tower body." Little Sunfish then pointed to the so-called air hole in the middle of the tower body and said.

Gawain stepped forward with great interest, but found that the vent could only reach his shoulders, so he stepped aside in a dignified manner. Anna went up to it, only to find that the structure of this wind hole was exactly the opposite of the fortress's archery port. It was in the shape of a trumpet, which allowed more wind to flow in and then blow out from the narrow opening in the wall, forming the most powerful energy. , a windmill tower can be drilled with four or even eight such wind holes, so that on the top of a mountain or fortress, no matter where the wind blows from any direction, the wheels of the equipment inside can be rotated. When the wind passes through the pipe of the wind hole and is injected inside, what greets it is the rotating shaft. The rotating shaft drives the arms surrounding it like a spinning wheel. Six, eight or even twelve arms are possible. Each arm has They are all nailed and covered with canvas to look like a lantern cover. Once the wind pours in, it will bulge, and then the bulge begins to rotate. Move, push the arm forward, and then the wind will make the second canvas bulge, and so on, driving the entire rotating shaft and windmill, which then drives the stone mill on it to rotate, and the upper layer is made into a funnel shape , the people above can continuously pour the grain into the stone mill along this funnel, and then the grain can be continuously ground.

"Interesting, wonderful!" After Anna read it, she was very satisfied with her hands on her waist. She was extremely satisfied with the two types of windmills jointly invented by the little sunfish and the pirates. Then she immediately ordered to give the pirate another chance. Increase the gold coin reward and promise to give him three times the holy salary real estate in the future (Seleucia's sailors and archers can also enjoy the holy salary).

Then Xiao Nizi took two steps and pondered, "The tower windmill on the shore is used for grinding flour and draining water, and the Persian windmill on the top of the mountain can be used for grinding flour and sawing wood, because Hardy Mountain Ridge and Kohler over there Adio Castle is rich in trees, so the large hydraulic workshop on the Alamein River is dedicated to printing, dyeing and tanning. Everything we do must adhere to the principles of rationality and efficiency. "

Gawain fully agreed with Anna's views. Just when everyone was about to enjoy the wind on the mountain, enjoy the meal and enjoy the scenery before going down the mountain, the Persian windmill model behind them suddenly made a sound in the wind. The abnormal sound, like a disintegrating ship, was getting louder and louder. Anna looked back in horror, but at this moment, black smoke and flames suddenly came out of the small tower's vents, with a roaring sound of shattering, "Ah, big barbarian!" Xiao Nizi was frightened. She hugged her head and braids, and soon she was hugged by Gawain and lifted to a safe area.

Hertomia calmly stopped in front of everyone. After a while, she turned back calmly and reported to everyone, "It doesn't matter, because the tower has collapsed and burned." What she said was absolutely correct. After Anna was snatched away, she immediately collapsed in front of the new official.

"Do you even need to tell me about this?" Little Sunfish angrily complained to the official who took his job away from him, "Why don't you tell me the reasons for the burning and collapse?"

"I'm sorry, this is your duty." Hertomia replied calmly, then she sat back on her footstool with the book and pen in hand, and recorded the disaster truthfully, which made Agni angry. Si Kuai started to smoke like the tower in front of her.

Finally, after careful investigation by the little sunfish, the cause of the accident was discovered. It turned out that the four wind holes were equipped with four rotating shafts and wind wheels. Today's wind was particularly strong, and it poured in everywhere, driving all the wind wheels to rub against the millstones and catch fire, burning everything.

"My dear friend, how can this problem be solved? If it is put into use, the windmill tower with grain piled up will catch fire, and the loss will be great. We must prevent it before it happens." Anna was still in shock, hugged Gawain and asked the little sunfish.

The little sunfish was also very smart. After thinking for a while, she said that the louver window could be covered on the wind hole, so that the size of the wind could be adjusted by turning the louver.

Although this problem was solved, everyone was a little embarrassed. The ash on the tip of Hetomiya's nose was not wiped off. "Hey, Imperial Ink Officer. Wipe that off." Gawain said, and Hetomiya temporarily gave up her duty of recording. She stood up from the stool and saluted the Grand Duke, and wiped off the stain with a silk handkerchief.

No one wanted to stay on the top of the mountain any longer, so after Anna approved the plan of "mobilizing manpower to start small-scale windmill construction trials in the Mut River Valley, Koler Adiou Castle, and the Alaman Land Bridge," they went down the mountain. (To be continued ~^~)
