Daming Crazy Emperor

Chapter 62 Minecart
Sun Chuanting, Lu Xiangsheng, Bi Ziyan, and Bi Zisu all took over their yamen with excitement, and Song Yingxing was the only one left standing there in the imperial study with an embarrassed expression on his face.

He didn't know why the emperor recruited him here. It was impossible for him to be a first-level official of the six ministers, and he was not even qualified to be the minister of the six ministers.

At this time, he even regretted it a little.

Alas, if I persisted and took the exam a few more times, I might have won the gold list.

As long as he has the honor of a Jinshi, given the respect the emperor places on his cronies, he might be able to be promoted to the six ministers.

The six books, Guangzong Yaozu, famous in the countryside.

What a pity, what a chance!

He was regretting secretly, Taichang suddenly smiled and waved: "Come on, Chang Geng, I will show you something."

See something?

what?
Song Yingxing walked over curiously and saw that there was nothing special on the desk except the Four Treasures of the Study.

At this time, Taichang took out a scroll from his arms in a little embarrassment, and slowly unfolded it: "My meticulous painting is not as good as yours, so you can't laugh when you see it."

Just kidding.

You are the emperor, who dares to laugh at you!
Song Yingxing craned his neck curiously, and was a little dumbfounded.

He really couldn't see what it was!
To be honest, there are really not many things in this world that he does not know. You must know that the "Heavenly Creation of Things" edited by him is called the encyclopedia of the seventeenth century by later generations, so what things can he not know.

What the hell is this?

Taichang saw that he had no expression other than curiosity, so he asked with a smile: "Chang Geng, how is the steam machine I told you about?"

Is this thing still related to that?

Song Yingxing was rather ashamed and said: "Forgive me, the emperor, the steam machine is really difficult to make. We have been busy for so long, and we have made the piston part you mentioned, and there is still a little air leakage."

The Pistons are not far from success if they are really made!

Taichang was quite excited and said: "Can the piston move? I mean, can the protruding connecting rod move up and down?"

Song Yingxing nodded slightly and said: "The connecting rod can move, as long as the steam is poured up and down in turn, the connecting rod can move up and down. The problem is that the connecting pipe is also leaking. Air leaks everywhere, and it will burn you to death."

Hahahaha, as long as it can move, as for the problem of air leakage, it seems that adding rubber seals will be fine.

By the way, rubber!
The rubber tree seems to have grown in Southeast Asia, and it seems that Daming has not introduced it yet.

This has to be quickly notified to the Shipping Department in Guangdong, and let them send someone to Nanyang to look for it.

Taichang was stunned for a moment, then nodded in approval and said, "It's pretty good to be able to move. Your progress is fast enough. As for the problem of air leakage, it needs a special thing to solve it. I will send someone to look for it."

Question, what exactly are you drawing?

Song Yingxing couldn't help but asked curiously: "Your Majesty, what are you painting?"

Taichang slapped his head when he heard the words, and quickly introduced: "This thing is called a mine cart, and it is used to transport ore."

In fact, the mine cart was already a bit like a simple freight train, so he asked about the steam engine. After all, it could be called a train if it was driven by a steam engine. Otherwise, it would be a rickshaw or an animal-drawn cart.

However, this steam engine cannot be successfully developed in a day or two, so he plans to make the tracks and carriages first, so that as long as the steam engine is successfully developed, the train can be made soon.

The mine car he drew is a dump truck with wheels, the kind that rolls over, with two tracks underneath.

It's normal that Song Yingxing can't recognize it, because there is no such thing in this world.

At the moment, mining is still carried on the back of the basket, and the ore is carried out of the mine purely by manpower.

He had never heard of minecarts.

He couldn't help asking again: "Your Majesty, is this thing made of wood or iron?"

Taichang said without hesitation: "Of course it's made of iron. Wooden ones can be broken a few times, and they may be smashed by ore after a few days."

Iron?

How heavy is this!
Song Yingxing was a little puzzled and said: "Your Majesty, after being filled with ore, this thing may weigh several thousand catties. If it weighs several thousand catties, even the wheels on the stone pavement may sink, and it will not be able to move at all!"

Uh, is it because I didn't draw clearly enough?
Taichang pointed to the rails and sleepers below: "So first lay the wooden squares underneath, and then lay the rails on top of the wooden squares, and let the wheels slide on the rails so that they won't sink in."

Song Yingxing really didn't see that Taichang's paintings were not very realistic, and he had never seen railroad tracks and sleepers, so he thought the emperor's paintings were the roads from the mines!
Uh, for the minecart to move, you have to lay rails?
Song Yingxing said cautiously: "Your Majesty, this is too troublesome. It takes a lot of effort just to lay the wooden squares and rails!"

Taichang nodded slightly and said: "It is indeed a bit troublesome, but sharpening a knife is no mistake for a woodcutter. Once this mine cart is available, the miner does not have to carry the ore back and forth. Moreover, it is not a problem to load several thousand catties of ore in the mine cart. It is exhausting for a person to carry hundreds of catties of ore in and out of the mine, as long as this thing is available, the speed of mining can be increased by more than ten times."

How many kilograms of ore?

Song Yingxing couldn't help asking again: "Does this thing still have to be drawn by a horse?"

Originally, horses were not used, but there is no locomotive now!

Taichang said helplessly: "It can be pulled by horses, oxen, mules, or even pushed by people. Let's make this thing first."

Uh, the problem, it seems that the thing you drew can’t be made!
Song Yingxing pointed to the iron basket in the middle and said, "Your Majesty, didn't you rivet it piece by piece, and cast the whole basket at once? I'm afraid it won't be possible to cast this one. Such a big basket might weigh a thousand catties, and the molten iron would pour down. Sand molds will be crushed."

Well, there's no welding at all, not even screws, just riveting.

The so-called riveting is to open a hole in the same position of two iron plates, and then smash a cylindrical iron rivet in, with the heads exposed on both sides, and finally smash both ends with a sledgehammer to secure it.

The riveting technology is not so good at the moment. Many places of those ships are riveted together. The rows of rivets are so neat that water can’t get in. It can be seen how good the riveting technology is at the moment. .

Alas, the screws have to be made, there are many places to be used in the future.

Question, what to use to process the screws?
Forget it, leave these problems to the professionals to use their brains.

Taichang was quite helpless and said: "If you say riveting, you can do it. In short, no matter what method is used, this thing has to be made first. In addition, I also thought of something. Let's see if you can find a way to make it. This thing is like this of."

As he spoke, he took out a blank piece of paper, picked up a brush and began to draw.

What he drew were screws and nuts. As for whether they can be made now, that's another matter. He had to let Song Yingxing know the purpose and benefits of this thing.

The two discussed it for a long time, and finally settled on the matter of the mine cart.

After Taichang finished speaking, he waved his hand and became the shopkeeper, but Song Yingxing frowned when he walked out of the imperial study.

Where can this thing be made?

He was paid by the emperor in such a muddleheaded manner that he even forgot to ask where he was going.

Uh, this.

He hesitated for a moment, but still walked to the Yamen of the Ministry of Industry.

The emperor probably didn't know where to do it, so he didn't talk about it.

These courtiers can't ask the emperor everything, if so, why does the emperor want them?

It would be better for him to go to Lu Xiangsheng first to find out. The Ministry of Industry not only has many workshops, but also many skilled craftsmen.
