Zhang Bin looked at the simple drilling machine in front of him, his heart was excited, don't look at its ugly appearance, but the value it contains is immeasurable, it can be said that this is an epoch-making machine!

The dream of replacing manpower with machinery has existed since ancient times, and the most common is to replace manpower with water and wind power.

However, the natural forces such as water and wind power are not widely used and are difficult to be fully promoted due to their instability, geographical limitations and even the influence of seasonal changes.

Steam power is different, this thing, to put it bluntly, only needs a boiler, a set of steam pistons, as for boiling water, it can be burned anywhere, at any time!

This means that it has gotten rid of the limitations of geography and time, and has the foundation for comprehensive promotion and wide application.

Coupled with its stable and long-lasting characteristics and strong strength, it is not a problem to replace manpower at all, and more importantly, it can also improve efficiency and quality.

For example, if the drilling machine in front of you is rotated by manpower, not to mention the speed and slowness, it may be interrupted suddenly, because people will always be tired, which is not only extremely inefficient, but also difficult to achieve smooth and consistent inner wall of the barrel.

It is different to use a drilling machine to process, the drill bit rotates quickly, the speed is also very stable, and it can endure for a long time, so that the inner wall of the barrel drilled out must be smooth and consistent, and the efficiency is even higher.

No, in less than a quarter of an hour, the barrel of about two feet long was drilled, and if someone drilled it, it would definitely not be able to finish drilling in half a day.

Wang Zheng asked people to close the valve, recruited two more helpers, turned the barrel off, replaced it with a larger drill bit, and continued to drill.

At this time, Zhang Bin felt that something was wrong, there should be a semi-circular arc-shaped groove behind the Franc cannon, how did this become a big round pipe?

He couldn't help but turn his head to Sun Yuanhua and said, "Chu Yang, is this processing the barrel of the Tiger Squat Cannon?" ”

When Sun Yuanhua heard this, he hurriedly replied: "Yes, my lord, wait a minute, there is something ready over there, and my subordinates will ask someone to move over." ”

With that, he ran to the side, called two people, and brought over a ready-made tiger squat cannon.

Zhang Bin took a look, this tiger squat cannon is about three feet long, the arm is thick, there are three iron hoops on the hoop to prevent explosion, the back is a semicircular groove, and there are two brackets under the first hoop in front, and the bracket grip is also deliberately cast into the shape of a tiger's claw, like this, it is really a bit like a tiger squatting all the time!

After a little look, he understood why Wang Zheng was processing a large round pipe at this time, it turned out that after they finished processing, they sawed off the middle half, kept a two-finger-wide ring in the back, and then welded a baffle in front of the ring, so that the second half of the Franc cannon was easy to process.

These people are really smart.

Zhang Bin sighed in his heart, these people are really extraordinary, and they can think of this method.

However, he always felt that something was wrong, but he couldn't remember what was wrong.

He thought for a while, and simply asked, "Chuyang, has this been tested, what is the range?" ”

When Sun Yuanhua heard this, he said embarrassedly: "My lord, according to your meaning, my subordinates have cast the outer circle of Zigong a little bigger, and it still needs to be processed before it can be used. ”

Son! Zhang Bin finally remembered that something was wrong, not that they were wrong to do so, but that the structure of the Franc cannon itself had limitations.

In his previous life, he had seen the scene of modern artillery firing on TV, and the most memorable thing was that it was loaded with shells.

The gunners operated it well, opened the cannon door, pushed the shell in, and then closed the gun door, and then, with a wave of the flag, the shell exploded out with a "boom".

The sub-gun of the Franc cannon is actually equivalent to a cannonball, but the sub-gun is not a one-time shell, and it can also be reloaded repeatedly!

Cannonballs, yes, herein lies the problem!

The reason why the Fran cannon is made of this open structure is not that the open is better than the closed type, the main thing is the problem of processing capacity, with the original processing level, it is difficult to do the mother and the child gun tightly, now with the machine tool, this processing problem is no longer a problem.

Zhang Bin said excitedly: "Chuyang, actually, you don't have to dig out this half, the entire round pipe is retained, just push Zi Gong from behind." ”

When Sun Yuanhua heard this, he thought for a while, and then asked embarrassedly: "My lord, how to install the cannon door behind this, there is no cannon door, as soon as the cannon is fired, won't this gun fly out from behind!" ”

Zhang Bin thought about it for a while, and then instructed: "Add two cannon lugs in the back, and connect them with the gun door with a fine iron round pin, and the right gun lug can be opened, and when you open the right side, the gun door can be turned to the left, so that it will not block the reloading." ”

When Sun Yuanhua heard this, he thought about it for a while, and his eyes couldn't help but light up, but he immediately said regretfully: "The structure that the adults said can be used as a cannon on the ship, but the back of this tiger squat cannon is on the ground, and there is no way to push Zi Gong from behind." ”

This is a problem, Zhang Bin frowned and pondered for a while, and soon thought of the field artillery, he immediately clapped his hands and said: "Make an artillery car, load the tiger squat cannon on the gun car, so that the back is suspended, not only is it convenient to load the gun, but also can adjust the direction at will, and most importantly, the maneuverability is stronger, with the gun car, whether it is pushed by people or horse-pulled, it is much more convenient than carrying it." ”

It is naturally more convenient to walk with a car than to walk, don't look at this tiger squatting cannon is only fifty pounds, a man in the prime of life can pick it up, it doesn't seem to be very strenuous, but it is standing still, if you run on your back, you can get tired of lying down when you run a mile!

However, at this time, there was no concept of a gun carriage, but there was a combat vehicle, and what was a gun carriage?

Sun Yuanhua asked puzzledly: "Dare to ask my lord, what is this artillery carriage?" ”

When Zhang Bin heard this, he gestured to the tiger squat cannon on the ground: "The gun carriage is a simplified two-wheeled vehicle specially equipped for artillery, this gun carriage is very simple, it is to make a platform for placing artillery, and cast a gun carriage with pig iron at the back, and install wheels on both sides, so that when marching, you can put the gun carriage on horseback and pull it directly." When fighting, just nail the gun carriage to the ground, and you can fire the cannon immediately! ”

The structure of the gun carriage is indeed simple, but no one thinks about it, Sun Yuanhua understood when he heard it, and he couldn't help but say excitedly: "My lord is wise, in this way, the transportation of the tiger squat cannon is much simpler, and the subordinates originally wanted to equip the tiger squat cannon with a carriage, with the gun carriage, this carriage is redundant and impractical." By the way, my lord, I wonder if you can add a shelf to the gun carriage and put the gun directly on it? ”

Shells on a gun carriage?

I really haven't seen this Zhang Bin before, but the Zi Gong is not an ordinary shell, but a gun barrel that can be reloaded, unlike the shell that has to be pulled back and reloaded with a primer after being used once, so there is still a certain reason for this Zi Gong to be transported with the mother gun.

He nodded directly and said, "Well, you just need to think about this." ”

Sometimes invention and creation do not need much strong professionalism, but more important is the idea and creativity, that is, the so-called inspiration, Zhang Bin from hundreds of years of experience and insight, can be said to be a source of inspiration, in many aspects of the role is terrible.

For example, this tiger squat artillery, after a little mention by him, was immediately upgraded to a field tiger squat artillery, you know, the European continent countries, it took two or three hundred years to upgrade the naval artillery or city defense artillery into field artillery!
