After the Qin Terracotta Warriors and Horses were discovered, after excavating the figurine pit, thousands of bronze weapons were excavated in the Terracotta Warriors and Horses pit, among which arrows were the majority, among these arrows, people found that all arrows almost had a unified production standard, triangular arrowheads, three edges were almost the same length, and the three sides were almost the same, archaeologists were stunned at that time, and then there was a series of speculations. Pen, fun, pavilion www. biquge。 info

In order to produce almost the same arrowheads, the standards were set, and the production tools at that time were backward, the arrowheads were first made into the pottery fan, then the bronze was melted and poured into the fan, and after it cooled, the pottery fan was removed, and the cast bronze arrowhead formed a shape, and then the craftsman polished it with a file and other tools.

One or two arrows are very elaborate and reasonable, which is understandable, but thousands of them have reached this standard, and archaeologists at that time had the inference that there was a simple machine in the Qin period, and this simple tool was the grinding wheel, a tool used to polish bronze arrowheads and other bronze weapons.

The grinding wheel is driven by manpower, so that the grinding wheel moves regularly at a uniform speed and polishes the bronze weapon.

But before, archaeology did not find similar simple machinery, so everything is in the speculation of later generations, until now, I saw the cabinet mechanism in the belly of the bronze giant, which is shocking and at the same time, it is enough to prove the inference of some people about the existence of simple machinery in the Qin Dynasty.

"I'll go, who brought this thing here?" Lao K didn't believe it when he saw it, he suspected that these two huge bronze statues were not the products of the Qin Dynasty, but that later people entered here to bluff people.

"Who would be so bored, put these two big bronze statues in the tomb, and don't want anything else, and we have been to many places in the dungeon, and we have not found any traces of theft, which shows that no one has ever set foot here since the moment the dungeon was closed." All kinds of signs can prove my words, and Lao K also said casually when he was surprised, and he closed his eyes at this time.

"The Chinese invented these complex things more than two thousand years ago?" Shangguan Yaxiong didn't make up his mind, and asked with a frown.

I shook my head: "Who knows." ”

In the belly of the bronze man, is a set of gear-based transmission mechanism, at a glance, just like the structure of a mechanical clock, several gears of different sizes meshed with each other, at that time this is absolutely unprecedented and amazing, if the ancients did not use this thing as a mechanism to set up anti-theft, for other purposes, such as clocks, then it is estimated that the world-famous is not Swiss clocks, but Chinese clocks.

It's a pity that, just like the gunpowder discovered in ancient China, it was used in events that had no substance, but in the hands of others, it played an infinite role.

"When you step on the threshold, the bronze giant will move, and he will swing a sledgehammer." I said, seemingly talking to myself, and then looking up in the bronze giant's belly.

This transmission is purely mechanical, so to make the bronze giant's arms swing up and drive the huge bronze hammer, there must be two transmission rods connected to the bronze man's arms in the bronze man's belly.

"Sure enough." I nodded, even proud of my discovery.

"Sure enough, what?" Old K then asked me.

The door on the bronze giant's body is not very open, and if my head sticks in and I have to turn on a flashlight, the other people's vision will be completely blocked, and nothing can be seen inside.

"There are two transmission rods connected to the arms of the bronze giant, which are used to control the transmission mechanism of the giant's hands and the large bronze hammer." My head is still in the belly of the bronze man and said to the old K and Shangguan Yaxiong outside.

"Let me see." Old K dragged my clothes and wanted to go in and take a look.

I carefully put my head out, but the hand that played the flashlight was still in the bronze man's stomach, and Lao K took the flashlight in the bronze man's stomach, and then poked his head in.

"Really, the hands of the giant's bronze man are like shadow puppets in a shadow puppet play, controlled by these two poles." Old K said inside, the voice was very small, and I could still hear it when I stood beside him.

"Qin Qi, this thing is amazing, it can be said that it was a robot more than two thousand years ago." The pangolin said to me.

Lao K stretched out his head after seeing enough, and Shangguan Yaxiong also leaned over to take the flashlight, she also wanted to take a look.

"That's it, or we move this bronze man out, and if we don't get it, we can go to the robot competition and apply for a patent or something." Old K can really pull it.

"This is a cultural relic, move out like this, participate in the robot competition, apply for a patent, walk out of this underground palace to ensure that someone comes to pick up the goods, you will wait for the rest of your life to live in prison, don't say that I am your brother, and I don't have time to see you." I stared at Shangguan Yaxiong's appearance of probing into the bronze man's stomach and scolded Lao K.

"Hey." Old K pushed me on the shoulder at this time, and then whispered to me, "I thought I could take advantage of it, but I didn't expect you to pick up this bargain, it's really a brother." ”

When I heard this, I immediately felt a little embarrassed, and I knew what Old K was talking about.

"Don't talk nonsense." I told Lao K to shut up, and glanced at Shangguan Yaxiong, who was twisting his ass to look at the scene in the bronze man's belly, and said to Lao K in a low voice, "Don't think nonsense in this kind of place, especially this kind of thing. ”

"Less garlic, in front of my brother and me, I don't care about you, you just admit it!" Old K said with a hippie smile.

With a wave of my little shovel, I simply ignored this boring guy.

"What are you talking about?" Shangguan Yaxiong said in the belly of the bronze man, and his voice had a kind of buzz of talking in a water tank.

I was stunned: "Didn't say anything, what did you see in it?" ”

This sentence is said very unnaturally, even I found out myself, what is inside, I am the first to see it, how can I not know.

"Same as you see." Shangguan Yaxiong's answer made me uncomfortable, and then she paused and said, "There are also below." ”

"Nonsense, of course there is below, otherwise would it still be a man?" Lao K answered quickly and answered Shangguan Yaxiong without thinking.

Shangguan Yaxiong took his head out and said to us, "Really, there is also a pole underneath. ”

Shangguan Yaxiong didn't know what Lao K's words meant at all, and he was sure that he saw it after he came out.

"You don't have to pay attention to him." I thought about it, and Shangguan Yaxiong's discovery was reasonable, so I asked, "Is it also a transmission rod connected to a gear?" ”

Shangguan Yaxiong nodded: "Hmm." ”

"That's the drive rod that connects the stone sill, it's the real mechanism." I glanced at the stone threshold.

"It's so far away, and it's so sensitive, as long as it touches the threshold, it will make the bronze giant swing the hammer, it's incredible." Old K pretended to think.

The bronze giant is not directly pressed on the side of the door, but moved a little to both sides, before the palace door is decayed, the temple door is pushed in, and the open temple door is not within reach of the bronze giant, so it is far away on the side of the door to see the small half of the bronze giant's body, which is also the reason why we can't see the bronze man outside the door just now.

"Maybe the ground is empty, from the feet of the bronze giant to the bottom of the threshold, and inside there is a special device connected to the stone threshold, controlled by weight, as soon as anything touches the threshold, the mechanism is immediately activated, it is the big copper hammer we just saw." I analyzed.
