Yin Shi also looked at Jiang Yifan, the expressions of Jiang Yifan and Zhao Gang talking were not as simple as gossiping, "Yuanfan bowed to you just now, is he entrusting you with something?" Hard? ”

Isn't that hard? It's just so hard! Jiang Yifan is about to burst into tears, your family Ah Yan, what is the name is not good, but it is also called Ye Xinyan, and Ah Yan has the same name and surname. If a girl in Qinghe Village is named Ye Xinyan, is Ah Yan the last life of this girl in Qinghe Village, as long as he is good to Ah Yan wholeheartedly, and then let his mother come to Qingyuan County to propose marriage?

Zhao Gang's expression was not much better than Jiang Yifan's, "It's nothing, Miss Biao brought us two extra pieces of cheese, I think she should save more silver, the more I talk about it." ”

This, it's really a trivial matter, Yin Shi complained: "Ah Yan has a lot of silver, but it's just two pieces of cheese, you just have to take it with you, where is the need to say so much." As he spoke, he turned to Jiang Yifan again, "Annoying Yuanfan to come early this time, you and Uncle Zhao get along well, you also know that Uncle Zhao is a hearty person, although he speaks straight, he is very easy to get along with." ”

Of course, what the mother-in-law said was correct, Jiang Yifan nodded hurriedly, "Madam said, Uncle Zhao has always been a good person, and he treats our juniors very well." ”

Zhao Gang was still frowning, why didn't he find out that this kid was so cheeky before, whose junior was he?

Ye Xinyan nodded, she didn't show shamelessness before, it was because she didn't need it, but now she needs it, so she didn't show it stingily at all.

Yin was relieved, Yuanfan was really an understanding and good boy. In the past, the two children were not well, and in the future, she had to persuade Ah Yan, she couldn't always show Yuanfan's face, it hurt the children's hearts so much.

…………

Sending Zhao Gang and his party away, Ye Xinyan's life returned to normal. In addition to accompanying Yin's daily business inspection, he worked with Wang Qiao and Zhou Biyao to trial-produce railed movable gantries and small cranes at other times.

Compared with small cranes, the production of movable gantries is relatively simple. A movable gantry that is tall enough to bear heavy loads will save a lot of labor on the construction site and improve efficiency.

The pulley block can be used on the gantry, which will also be much more convenient. However, if you want to transport heavier materials and materials, you have to use other lifting equipment.

The best tool to use with the gantry is the inverted chain, another name for a purely mechanical lifting machine that can lift small heavy objects. The inverted chain is mounted on the rail gantry, which can play the ultimate role of the gantry.

In the matter of inverted chains, Ye Xinyan himself is not very proficient. She could only explain her idea and the principle of the inverted chain axle to Wang Qiao, and let Wang Qiao solve it according to his own understanding. Ye Xinyan pointed out some things about the shape, structure and braking in a timely manner.

In this way, even if this thing that can alarm the equipment industry of the Great Xia Dynasty is made, everyone will not doubt her, but will think that it is the result of everyone's collective efforts. Moreover, she is really not an expert, but only has a rough idea.

Things in the world are so peculiar, most things, in fact, are a lack of imagination, once there is the support of imagination, and some key reminders, many things that seem almost impossible can be done.

Although Zhou Baguio is a girl, she is very aura in technology. Wang Qiao, on the other hand, is very proficient in the principles of various appliances and mechanisms, and is better at having a good imagination and unique vision, and can grasp the key when solving problems.

Although the inverted chain is a relatively complex instrument, there are dozens of parts and components for a small thing. But Ye Xinyan felt that with Wang Qiao and Zhou Biyao as assistants, they could make this thing.

She generally knows how the chain works, and as for the meshing, size, transmission, and braking of the components, it needs to be tested step by step, and gradually improve the unsuitable places to achieve ultimate success.

The first step of the model, of course, is still the use of tough wood, the construction line is some of the handicraft carpentry, and Wang Qiao is also good at this. As long as the wooden model can be successfully driven, various parts can be processed from pig or wrought iron according to the wooden model.

Wang Qiao led seven or eight craftsmen to keep material and grinding parts every day, testing them, and scrapping them. Then the parts are cut and grinded......

After five or six days in this way, after repeated running-in tests, several main parts of the inverted chain were made, which could be transmitted to each other, and there was a simple prototype. But it's still far from being usable.

Ye Xinyan was a little worried. At this rate, when will the gantry be really used? An inverted chain will consume people to death, and there are other things to do to make a gantry, similar to the problems of universal wheels, track connections, and load-bearing, all of which need to be solved.

…………

When Jiang Yifan came over, Ye Xinyan was worried about the sketch of her words. She really thought about things simply, it was easy for her to think about it and talk about it, but in this era, with the support of this kind of productivity and technology, it is really too difficult to make mechanical tools that are not available in this world.

At the beginning of spring, when Qi Younian led people to Yuyuan City to start construction, Ye Xinyan left Wang Qiao behind, Jiang Yifan was still a little uncomfortable, although there was Mrs. Shizi, and he also believed that Ye Xinyan's personality would not be stalked in this kind of thing, but he still came a few more times.

When he saw Zhou Biyao stay and do things with Ye Xinyan, he was completely relieved. Ah Yan is really a strange woman, not only cunning and straightforward, but also has a good character. is open-minded, even a man can't compare, and it doesn't affect her doing the right thing because she was rejected by Wang Qiao.

When Jiang Yifan was outside just now, he had already seen Wang Qiao and others experimenting with a wooden Karakuri thing, he asked curiously, but he was very suspicious that such a thing less than a foot square could lift a thousand catties of heavy objects.

When I entered the work room, I saw the large table in front of Ye Xinyan, full of sketches. And Ye Xinyan's eyes stared at the corner of the room, looking extremely unhappy.

Jiang Yifan waved his hand at Zhou Biyao at the other end of the room, signaling her not to make a sound. He approached the table and took a look at the sketches that could be seen on it, hmm,...... I can't see the doorway at all.

Jiang Yifan coughed lightly, Ye Xinyan turned his head, and thought about it, she is the granddaughter of An Guogong, and her status is very high, so there is no need to pretend to give him a small county official salute, right? Importantly, she was in a bad mood.

Then she turned her head back and continued to look at the corner.

Zhou Biyao hurriedly lowered her head and continued to draw the drawings of Wang Qiao's recent return and revised the size and shape. She didn't see anything, she didn't see Sister Qi being rude to Lord Jiang, and she didn't see that Lord Jiang was not only not angry or embarrassed, but actually had a smile on her face.

Jiang Yifan looked at Ye Xinyan with a smile, picked up a sketch that looked like the overall structure was quite complete, and said, "Can you tell me what you are going to do?" You can't do it like this, whether the thing can be used or not, but you have to make it and try it, and you have to come to a conclusion. In this way, people are consumed here, not only doing day work, but also delaying things. ”

Ye Xinyan turned around, quite knowledgeable, didn't speak layman's terms. Reading a book and finding the latest chapters by yourself? You're out, WeChat attention Beauty editor helps you find books! It's really a good book to flirt with girls!
