【Broadcast】Pay attention to "Reading at the starting point", get the first-hand news of 515 red envelopes, and students who have not grabbed red envelopes after the Chinese New Year can show their skills this time.

The first molten iron was baked on the second day, and under the care of Blacksmith Zhang and others, the iron furnace was made very successfully, and there were no major problems.

After the molten iron cooled, the material was 600 catties, although it was only crude iron, but Wang Teng was already very satisfied.

As long as the furnace successfully produces water, the next step is to improve the quality and reduce waste is just a step-by-step thing.

Spring ploughing is imminent, and Wang Teng plans to make a batch of tillage tools.

At this time, the plough was mostly made of wood, and only iron tools were arranged in the "gluttonous wall" position of the soil, so although the cost was saved, it was not durable, and the effect was not good when ploughing the ground.

Wang Teng drew drawings according to the impression of the iron plough in later generations, changed the plough to iron wheels, omitted the plow arrows, and dug a hole groove in the middle of the plough tip, so that the wooden wedge can be used to fix the iron wheel and adjust the depth, so that the plough body structure is simplified without affecting the efficiency of cultivated land, and also makes the plough more durable and durable, which not only prolongs the use time, but also saves production costs.

In a flash of inspiration, Wang Teng hurriedly moved his pen and drew the shape of the iron plow.

"Blacksmith Zhang, come and see this iron plow"

Zhang blacksmith has become the head of the craftsman, Wang Teng's drawings made him amazed, at this time the folk Quyuan plow has lasted for hundreds of years, and there is not much change, however, Wang Teng's few strokes are like a stroke of genius, with Zhang Blacksmith's experience, it is not difficult to see the role of the iron plow, but, in this way, the cost is afraid to be large, "My lord, the wooden to iron is natural and durable, just." This silver ......"

Wang Teng smiled and said: "Don't worry about the silver, how many days can you do this plow?" ”

Blacksmith Zhang hesitated slightly, and said, "One day is enough!" ”

Wang Teng showed his approval: "Okay, after making the iron plow, I will find a ploughing ox to try the effect, and if you have any ideas, you can improve it." ”

Zhang Blacksmith's heart is surging, if this kind of iron plough is really beneficial to the people's production. There must be a reward in the future, although he is old, but he just married a wife a few days ago, and now it is the time to strive for progress, so he is naturally willing to work hard.

Chinese craftsmen have never lacked creativity or hard work, and the only thing they lack is motivation.

When Wang Teng handed over the drawings, he deliberately mentioned that as long as the iron plough was built before sunset. There must be a lot of rewards.

Now that the power is also there, the craftsmen have made the iron plough in only one hour under the leadership of Blacksmith Zhang.

However, thinking of Wang Teng's advice, a young blacksmith couldn't help but mutter: "Why do I feel that the plowshare of this iron plough should be changed to be smaller?" ”

Several other older craftsmen immediately scolded: "San'er, the adults gave us the drawings, as long as we make them step by step, we have no fault, could it be that you really take the adult's politeness as an order?" ”

The blacksmith who was called San'er did not dare to make a sound. The few people next to him are all well-known craftsmen, and it is not an exaggeration to say that they are his masters. was scolded by them, San'er could only hang his head and keep silent.

Blacksmith Zhang had the heart to speak, but Wang Teng was urging him so tightly that he didn't dare to delay for too long, if San'er really had an idea. There will be opportunities in the future.

After some discussion, several craftsmen decided to try it out.

Anyway, it's still early, and if the iron plow is really useful, it will be easy to get to a thousand households.

The elders left happily, but the three children in the craftsman's shed did not go out. He stared intently at the iron plough on the drawing, and muttered: "It shouldn't be like this, my plowshare is too big, and it is very difficult to pull up, if I change it again, it will be much better if I change it again." ”

After that, San'er seemed to be a demon, he looked around, and the red-hot iron was still on the stove.

The observation just now gave San'er a new understanding of the production of the iron plow, although it was done by one person, but the speed was not half a minute slower.

"Bang bang bang", the fire splashed everywhere, and the sweat was profuse.

By the time the craftsmen who had gone out to test the iron plough returned, San'er had already built an iron plough on his own.

After all, Wang Teng was not a master designer, and it was impossible for him to memorize every detail of the iron plow, so the drawings he drew for the craftsmen only vaguely drew the outline of the iron plough and the role of each part.

As for the shape of the specific parts, it is entirely up to the craftsmen to play.

San'er's iron plough is slightly modified on the basis of the drawings, compared with the original, his iron plough is not only lighter, but also can be equipped with handles, changed to an iron plough pulled by man.

Cattle are scarce in the villages, and a family of several hundred often does not have even ten cows.

At this time, the manpower plow is particularly important.

Seeing San'er's iron plow, the faces of several craftsmen changed, they didn't expect Chen San to make an iron plough alone, how could they be embarrassed by their elders?

However, as an elder, you still have to have the bearing to promote the future.

Several craftsmen glanced at each other, and were about to say more, when Blacksmith Zhang smiled: "Why are you still stunned?" It's getting dark, show your iron plough to the adults, and let him see what needs to be changed! ”

Chen San was worried, and when he heard the permission of his predecessors, he was immediately overjoyed, and he shook his head again and again, and said: "Okay, a few uncles are resting, I will carry these two iron plows, and I will carry them." ”

A few craftsmen were noncommittal, if it weren't for Chen San's knowledge and interest in the past and his well-behaved behavior, they wouldn't let Chen San go with him if they said anything today.

Compared with the previous wooden plough, the iron plough now ploughs deeper soil, and with the same strength, ploughing at different depths, this is a great innovation.

Chen San's changes looked at the craftsmen, although they were a little jerky, but compared to the previous handle, it seemed to be a lot better.

Not long after, two iron plows were sent to Wang Teng.

That's right, it's what Wang Teng imagined the iron plough to look like.

In later generations, since the birth of the Quyuan plow, for thousands of years, the Chinese people have been using, except for slight changes in the details, the shape of the wooden plough has not changed at all.

In the Ming and Qing dynasties, the forging of iron tools has been extremely skilled, and craftsmen began to try to introduce iron tools into wooden ploughs, but iron tools are expensive, and after adding iron, the price of wooden plows will rise several times!

For ordinary people, this is unacceptable.

Wang Teng didn't think so, he rubbed his plow arm, raised his head and asked, "How?" Is it a little less effort than the previous wooden plow? ”

"It is several times stronger, the previous wooden plough turned over the soil was only five inches, and now this iron plough is enough to turn over more than nine inches of soil."

At this time, Wang Teng noticed that the craftsman actually sent two samples of iron ploughs, at a cursory glance, there was no difference between the two, but after careful inspection, Wang Teng found that the other iron plough with rough arms was obviously more in line with the appearance of the iron plough in his heart, and he immediately wondered: "Hey, how can there be two iron plows?" What's going on with this one? ”
