In order to facilitate work, Lao Zheng, a carpenter in the detachment, has made a lot of chicken buses for a while.

The chicken cart is actually a wheelbarrow, where a large wooden hard tree is sawed close to the hardest part of the root, and a large wicker frame is added to the frame.

Because it pushes and sways like a rooster walking, it is called a chicken cart.

This thing doesn't look good, but it's relatively convenient to use, and the raw materials are easy to obtain, so it's very common in rural areas.

In the afternoon, the coke oven yard began to be lively.

Many of the people who came from the copper mine gathered at the foot of the huge coal mountain to select the coal mine again, and the selected coal mine was loaded into the chicken bus, and then there were men pushing the crunching chicken bus to transport the coal mine into the coke oven, and under the command of Xu Jiunian, it was neatly stacked in the coke oven to make the final preparations for coking.

After teaching the health team emergency care for a day, Zhang Ran, who was dizzy, came over and saw the chicken bus pushing coal, and immediately had a lot of fun, and he was happy to try it.

He was relatively tall at this time, and the detachment usually took care of him a lot in terms of life, and his strength was naturally not small.

The wooden wheels are very hard, and the axles are hard to touch, there is nothing else at all, and it is extremely difficult to push, plus this thing has never been finished, and it has not been balanced for a while.

"Captain Zhang, I'll just say you can't do it......"

"Captain Zhang, we are all convinced that you do anything else, but this coolie, Captain Zhang, you are still far away!"

The people laughed kindly and pulled Zhang Ran up, Lao Zheng looked at Zhang Ran with disgust, and said that the chicken bus he made was said to be good, if you can't even push the chicken bus made by my Lao Zheng, it is estimated that you will have no fate with high-tech things like chicken buses in the future......

I'm driving a four-wheeled car, okay......

Zhang Ran thought with a smile, and at the same time helped to load the scattered coal onto the car again, while looking at the connection between the wooden wheels and the axle of the chicken bus, he had some ideas in his heart.

The biggest advantage of the chicken bus is that when it moves, there is a focus point on the whole body, as long as it is not a hill climb, a palm-wide road on the flat ground can push more than 100 or 200 pounds of things to run fast!

The chicken bus built by Lao Zheng is really good, and it is usually quite light to push, but the connection between the wheel and the axle is passed through by an iron rod, if it is loaded with heavy objects, it will not work!

"Although there is no rubber now, even if the industrial level is not enough, it may not be possible to manufacture tires, but if you can build a bearing to install on this wheel, it will be at least twice as easy to push!"

Zhang Ranxin said that if the bearings were really made and a batch of such chicken buses were built, it would be too helpful to the detachment!

Not to mention that in the future, when the detachment fights outside, it will be much easier for the people to use such wheelbarrows to transport combat materials and wounded for the team, so it is said that the current copper mines have to be transported on the shoulders of the common people, and they will only be transported once or twice every day when they are tired and vomit blood.

This is still the Jianzishan copper mine close to this side, in case Cangshui County is taken in the future, the coal mine of Longwanggou will be transported here, and there will be more than 100 miles in the middle!

It's really all carried on people's shoulders, and it takes a few people to go back and forth for seven or eight days or ten days to transport a trip, and a trip is only a hundred and ten catties of coal at most?

Although after entering the Dongjiang River from Cangshui, the mountains around the base area still have to be backed by backs, but if the chicken bus is used on the 100-mile flat road, won't it also save a lot of labor, and also increase the amount of coal transported at one time?

"I'll go back to the second workshop to find Cheng Dongguo, Cui Sanyuan and Niu Da, I have to give them a death order, no matter what, I have to get this bearing out for me!"

Thinking of these benefits, Zhang Ran was secretly excited at the same time, and then entered the coke oven where the coal was being fed.

"It's all porcelain and don't leave a little gap!"

Xu Jiunian shouted loudly in the furnace with his hands behind his back, commanding several apprentices to load coal, and greeted Zhang Ran with a smile: "Captain Zhang, you are also fortunate to find my Lao Xu, if you change to someone else, you want to smelt copper and coke, these skills, not everyone can ......"

"Master Xu, you're tired!"

Zhang Ran laughed embarrassedly, and said in his heart that although Lao Tzu had indeed never seen coke or anything, he couldn't stand Lao Tzu's knowledge......

Isn't this soil method of coking the same as the heap burning method of charcoal?

The coal is placed in a coke oven to isolate the air to dry distill various components of the coal that are harmful to smelting, and finally the part with the highest calorific value is coke......

Who is this thing difficult to live in?

If you haven't eaten pork, have you ever seen a pig run?

Thinking like this in his heart, but Zhang Ran didn't dislike it very much, Xu Jiunian, who had decided to fire it early, said more, took a turn in the coke oven, and went to find Deng Fang.

Deng Fang was still conducting the final inspection of the device for extracting coal tar, and he had already seen through Zhang Ran's omniscient appearance, nothing would happen, but he only knew the true face of ambiguity, so he didn't bother to bother with him at all.

When it was dark, the coal in the coke oven was finally filled, and after the final inlet was closed, Xu Jiunian gave an order and began to ignite.

The fuel used in coking is naturally a second-class coal mine that has been selected.

The temperature of the furnace rises rapidly after ignition.

Under the high temperature, the coal in the furnace is not able to get the necessary air for full combustion, and all kinds of impurities are constantly seeping out, and finally turn into thick smoke rising from the smoke outlet, and then enter several clay jars where Deng Fang collects coal tar, and most of the coal tar is retained under the action of condensation.

The process of coking is not a one-time process, and it takes at least two days to complete the refining of such a large furnace of coking coal.

Xu Jiunian checked everywhere on the furnace body, and after confirming that there were no cracks and smoke leakage, he said that there was no big problem, and then he waited for the coking to be completed, sealed the furnace and waited for the coking coal inside to be extinguished and cooled, and then the refined coking coal could be released, and then filled into the next batch of coal, and ignited and refined again.

Zhang Ran nodded.

Although he knows this kind of local coking, every time he has to wait for one furnace to be finished and then close the furnace, and then refine the next furnace after the coke is finished, which not only has a great impact on the service life of the coke oven in the case of thermal expansion and cold contraction, but also the efficiency of coking coal refining is extremely low.

It would be best if there was a way to improve the process, and to be able to feed and refine at any time, and produce finished products at any time, just like the copper smelting furnace over there......

But looking at Xu Jiunian like this, it is estimated that it is impossible to rely on him!

This is a guy who will only stand on the little means accumulated by his ancestors, and he will not listen to any opinions!

Anyway, there is not much coal bought back now, and at most it will be finished in a few furnaces.

If you want to make a large amount of coking, you have to wait until you take the warehouse water, and the coal mine in Longwanggou is transported from afar and continuously, so he is not in a hurry to improve the coking process.

Therefore, Zhang Ran did not discuss with Xu Jiunian about improving the coking process at all, and when the apprentices arranged by Wang Changtian came out, a large amount of coal came in, and he would discuss with those apprentices after Xu Jiunian was fired.

The ordinary people who helped in the coking plant deserved not to leave - this helped the detachment, and of course they had to finish dinner before leaving.

Not only Zhang Ran, but even Wang Changtian saw these things very openly.

If you want the common people to support the base areas from the bottom of their hearts, it is far from enough to rely on ideological propaganda and consciousness alone!

These things can only be means, and the most important thing is to let the people see tangible benefits, such as people helping, then it is time for people to eat and go back!

Only in this way, accumulate bit by bit, let the people know that as long as they support the detachment, the detachment will not let them suffer, then they will truly support the detachment, and when the crisis comes, resolutely stand with the detachment, face it together, and stand together through thick and thin.

Deng Ying moved out of the blackboard and wrote the pinyin letters, teaching everyone to read letter by letter.

a，o，e……

I have to say that when hundreds of people read pinyin together, it still looks quite shocking.

Especially Zhang Ran, the sense of accomplishment that he has made great contributions to this era, to the prosperity of the country and the rise of the nation......

Well, it's beautiful.

Under the teaching of Deng Ying and the promotion of Wang Changtian and Deng Ying's political tasks, the popularization of pinyin was rapidly spread in the base areas.

This is true not only on the detachment's side, but also in all villages.

Before starting for work in the morning, gather to have section a, o, e, and in the evening, when it gets dark, everyone takes their rice bowls and sits in a row in the yard to section b, p, m......

Even a few people who carry copper mine earners on their backs walk together, they have to come to the section j, q, x......

Among them, there is a role in promotion, and the people's desire for literacy and knowledge makes them spontaneously want to master words.

Before, there was no chance, but now that they have the opportunity, they burst out with great enthusiasm.

Although the result may not be so satisfactory, knowing one more word is a great satisfaction for everyone, and that is from the satisfaction of the soul, the fulfillment of the spirit!

The training of the health team continues.

Wang Changtian failed to find the Western doctor Zhang Ran wanted, and even the old Chinese medicine doctor in the base area, he couldn't bring it back.

However, I brought back a person who can treat bruises, and usually collects some herbs in the mountains to help the villagers treat a fall injury, headache and brain fever, and help make up for some barefoot doctors at home.

"Captain Zhang, my name is Han Jinshan......"

The honest young man introduced himself shyly.

For a guy like Zhang Ran, who has been completely conquered by Western medicine, seeing Han Jinshan, a barefoot doctor, it is impossible not to be disappointed, but he still welcomes him again and again, and asks the other party to stay and learn first with him, and take his time with the rest.

But what Zhang Ran didn't expect was that it was this barefoot doctor Han Jinshan, who really surprised him in the next performance!
