Lin Feng grabbed Sun Cuo, who was so busy that he couldn't even lift his head, and dragged him to the side where it was not so noisy.

Sun Cuo was a little unhappy at first, although he left, but a pair of eyes kept looking at the hot stove, and his mouth was still muttering: "My strange weapon is almost finished!" ”

Lin Feng couldn't help but secretly admire, didn't he rely on this obsession and concentration to do technical work! Lin Feng gently patted away the dirt stuck to Sun Cuo's bare shoulder, and said, "Sharpen the knife and don't cut the woodman by mistake." Brother Sun, didn't I tell you to consider using the water power of the waterfall the other day? Do you have any clue? ”

"This ...... I've thought about water squeezes and drains, but I don't think they're practical. Sun Cuo scratched his messy hair and said with some embarrassment.

As early as the Western Han Dynasty, there was a water mill in China, which was mainly used to process grain at first, and later developed into the use of pounding pulp and crushing ore. The principle of the water mill is mainly by the water flow impulse vertical water wheel, and the short horizontal wood on the axle moves the tip of the mill to promote the head of the mill to fall together for pounding.

As for the water drain, the connecting rod is driven by the water wheel to push the blower, which is a smelting blower driven by water power. In the early years of the Eastern Han Dynasty, Nanyang Taishou Du Shi invented a tool that uses hydraulic power to agitate the bellows, that is, the famous Du Shi water drain, which is more than 1,000 years earlier than the appearance of similar machinery in Europe.

Lin Feng was a little strange and asked, "What are you doing?" "Water mill and water drain are all techniques that have been used for many years, and it stands to reason that there should be no such problems.

"I've seen these things before, and I feel like they're slow, they're not very dynamic, and they're hard to control. I think the water drain blast is as good as the bellows you made! Sun Cuo buried his head in thought for a while and said.

It's true, the piston bellows are an invention that goes beyond water drainage. Lin Feng lowered his head and thought for a while, then found a branch and drew it on the ground. Lin Feng scribbled back and forth for a while, then raised his head and said to Sun Cuo, "Brother Sun, come and take a look." ”

Sun Cuo took a lantern from the side and came over, and saw Lin Feng drawing three strange things on the ground. The first is a long stick with a circle of gears in the middle and a large fan blade at the end; The second is a hammer-like thing, but with a square hole in the tail handle; The third resembles a strange object folded from a five-section stick weapon.

Seeing Sun Cuo's puzzled eyes, Lin Feng stopped selling Guan Zi and explained them one by one: "The first one is that I want you to make a long iron rod, one side is a square cylinder, an iron gear is added in the middle, and a wooden blade is installed on the tail on the other side. The falling water of the waterfall hits the blades, causing the rods and gears to rotate at a constant speed. The second is to fix a striking hammer at the front end of the iron rod, and use the rotation of the iron rod to drive the hammer to rotate and strike, and use this force to hit the unformed weapon. As for the dynamics and rhythm you mentioned, we can consider making hammers of different lengths and sizes to control them. ”

"That's a good idea, but there's going to be a tilt angle problem with that hammer." Sun Cuo's brows were twisted, and he pinched his chin with his hand and said.

"That's a small problem, the hammer head can make a hammer head with a certain slope of the hammer surface according to the actual measurement, or find a way to control the forged weapon to maintain a certain angle." Lin Feng replied.

"The hammer is always a big circle, where is the weapon to be forged?" Sun Cuo continued to ask.

"That's a big problem. My consideration was to erect an iron platform with wheels next to it, and someone was responsible for controlling the time and angle of the iron platform's advancement. "Lin Feng also has a headache, so he requires a strong control ability for the person who pushes the iron platform, but he is suffering from the fact that there are no mechanical professionals around him now! It seems that there must be a few good looks in the talent selection ceremony.

"Well, I'll think about it and try to cast a few with Fan, if not, try it first! So what's the third one? Sun Cuo touched his head and pointed to a third strange thing.

"This is equipped with a gear on the iron rod, and the two are meshed through other gears in the middle, driving such a crank push rod to push back and forth in a straight direction, and at the same time of forging weapons, use water power to blow the bellows, so that the people who specialize in blowing can also be liberated." Lin Feng explained.

"It's a great idea!" Sun Cuo nodded and said.

Lin Feng got up from the ground, patted Sun Cuo's shoulder, and said, "I'm just providing an idea, and I have to bother Brother Sun to try more tests." ”

"No problem! If it doesn't work, let them go back to their parents' house again, and throw them back into the furnace to refine them again! Sun Co grinned. Perhaps because there was hope of getting rid of the fate of the sledgehammer from then on, Sun Cuo, who was in an extremely unrelaxed mood, actually came up with a witty remark.

Lin Feng was also amused by his rare humor.

In fact, there are still many details that need to be liberated in Lin Feng's so-called invention, but they cannot be solved for the time being due to the limitations of this era. For example, without a measuring stick accurate to at least the millimeter and a precisely controlled lathe, the hammer of the suit and the gears installed in the suit may run aground due to meshing problems.

Lin Feng shook his head, put these problems into the hands of professionals and then worked hard to solve them, and then asked, "Brother Sun, has that iron mine begun to be explored?" ”

"Well, I've been digging there a few times every day, and you can see the black and gray iron ore when you dig one or two feet down, and it seems to have a certain magnetism, but I'm very worried, how to mine iron ore, how to sieve it, how to purify it, I'm not very good at it!" Sun Cuo said worriedly.

It seems that the iron ore here is mainly magnetite, and the ore can be screened by magnetic separation, which is very convenient to process; However, the magnetite structure is relatively fine, and the reducibility is poor. However, it seems that Lin Feng can only look at Baoshan now and return empty-handed.

Alas, all kinds of professionals have become the biggest bottleneck for their next expansion and development! Lin Feng sighed secretly in his heart, but he didn't show it on the surface, and said to Sun Cuo: "That's it, on the one hand, let's try to dig a part of it in a small area first, on the other hand, when you go to buy iron, secretly inquire if there are any masters of mining and processing ores, if it really doesn't work, we can only recruit people with high salaries!" ”

"Well, let's do it. Okay, it's a little late, I see your eyes can't be opened, go and rest. Sun Cuo looked at Lin Feng and said comfortingly.

It's okay if Sun Cuo doesn't say it, when he says this, Lin Feng immediately feels that his head is a little heavy, and at the end of this long day, he is about to reach his physical limit. So, he said hello to Sun Cuo and walked back along the barely visible path.

Sun Cuo hurried two steps, handed the lantern in his hand to Lin Feng, and patted Lin Feng's shoulder.

Lin Feng took the lantern a little numbly, and suddenly didn't realize that Sun Cuo's hand was patted on the shoulder, and his mind was full of a question: how can we quickly search for more practical talents?
