According to Li Mengxi's analysis, the curved shaft plow can be divided into multiple components such as the plow head, plowshare, plow arm, armrest, and plow bed. The size, material, shape, and installation angle of each component are test points. Testing in this way is bound to be cumbersome.

To test the plowhead, Li Mengxi ordered the blacksmiths to bring over the plowshares they had made. There were seven plowshares in total. Six of them were the same as ordinary plowheads. The remaining one that was different looked particularly huge and was a triangle with convex edges.

Prismatic plow head.

After looking at the works made by the blacksmiths, Li Mengxi felt that although the craftsmen were indeed experienced and wise, ordinary craftsmen were less imaginative after all. Most of the craftsmen could only think of making ordinary plowheads, and like

Arrow-shaped, fusiform, no one can think of it.

Among the seven iron plow heads, the only one worthy of testing is the largest and huge triangular convex plow head. After installing it on the curved shaft plow, the oxen was then harnessed and the test started.

The soil was frozen hard in winter, and the old ox stretched out its neck and dragged hard in front of it. With the forward pulling force, the plow sank deeply into the soil.

As the test continued, Li Mengxi did not find out what advantages this special plow head had over other ordinary plow heads. Instead, he found out that the iron plow head was too big, as big as a bucket, and plowed the ground.

When he was young, he ate too much dirt, and the cow's strength was limited. If he ate too much dirt, the old cow couldn't pull it.

Sure enough, the size of the plow head will affect the efficiency of plowing.

As for the appropriate size of the plow head, Li Mengxi judged it from the straight plow. The straight plow of the Han Dynasty had an unscientific structure and was not efficient in utilizing force, so the plow head was small and the soil was not plowed deeply.

The curved shaft plow has a higher utilization rate of animal power and can plow deeper soil, so a larger plow can be used to dig deeper into the soil.

Therefore, the size of the plow head of the curved shaft plow must be larger.

So, Li Mengxi said to the blacksmiths, "You all know how big the straight plow is, right? Compared with the straight plow, the plow head of the curved shaft plow is larger, about one-third larger."

After explaining the size, Li Mengxi thought about it again, and there were still many arrangements to be made in the shape of the plow head.

Li Mengxi believes that more efficient plow head shapes may include arrow-shaped, fusiform, streamlined, etc.

As for arrowheads, there are various types of arrowheads. Li Mengxi simply went to the ordnance warehouse, pulled out the stored arrows, and picked out different ones when he found them. In the end, he found that the types of arrowheads were very complicated.

Among the many arrows, there are spade-shaped arrows, triangular sharp ones, armor-breaking cones, which are pyramid-shaped, and crescent-shaped arrows. Some arrowheads are similar to willow leaves, with thin ends and a slightly wider center.

Shape, there are arrows, let's call them slice arrows, the arrowheads are very flat and wide.

There are also arrowheads, the arrowhead looks like an iron rod with a finely ground top, like a needle, let's call it a needle-shaped arrow.

These are iron arrowheads, a lot of them.

In addition to these military arrowheads, there are also some inferior clay arrowheads whose arrowheads are made from dog teeth.

Li Mengxi took the canine-tooth arrow and looked at it again and again. He thought, when a plow turns over soil, does it follow the principle of teeth cutting into food? Can the curved canine-shaped plow head be useful?

Anyway, one more was not much, so Li Mengxi also included the arrowheads of the canine-tooth arrows in the test.

Li Mengxi left the ordnance warehouse with a large pile of arrows in his arms. He found the arrowheads among the craftsmen and distributed them to everyone, and told the blacksmiths to enlarge the arrowheads and make plow heads according to the shape of the arrowheads.

"Everyone remember that for all the plows you make, it doesn't matter whether they are lighter or heavier, but they must be the same length, width, and width."

This requirement is because for a cow, the plow head should be lighter, and the extra three or two kilograms of iron will not put pressure on the cow. The resistance when plowing is mainly based on the amount of soil being hugged. If the soil is hugged more, it will naturally It needs to be heavier, so the width of the plow is an important influencing factor. If it is wider, it will be heavier when plowing.

The arrows were sent out, and each of the blacksmiths had to create one of the shapes.

For their respective tasks, Li Mengxi had other requirements, such as a plow head in the shape of an armor-breaking cone. Li Mengxi said that two types could be made, one completely imitating an armor-breaking cone, with three or four edges, and the other with one edge removed. The bottom edge was changed to be flat.

Considering that the plow has to move on the soil, after all, it is not exactly the same as the arrow, so you may have to consider the impact of movement.

Lin Lin finally worked it out, and according to Li Mengxi's request, the blacksmiths were able to build a total of thirty-four plow heads.

There are too many shapes that can be tested for the plow head, but the plowshare is simple. For the plowshare, it is equivalent to a push plate, which is used to push the excavated soil to both sides to open a path when plowing.

The plowshare is just a long iron piece with a curvature, so the only things that need to be considered are the curvature and length of the iron piece. It is enough to make a plowshare with a dozen or so arcs with different lengths and widths.

Further down, the plow arms, plow bed and handrails are the work of carpenters.

After all the tasks are assigned, the carpenters need to make eight types of plow arms, four types of plow boards, straight and curved handrails, and various degrees and angles, a total of eighteen types.

In total, there are nearly a hundred parts of various types of curved shaft plows that need to be made.

The heavy tasks are pressed down, and I have to wait for at least another day.

After a busy day, when night falls, the craftsmen are far from finished.

On the fourth day of the first lunar month, it was early in the morning and shortly after breakfast, the soldiers came to report that someone was coming from Zhuozhou.

Li Mengxi and Guan Yu immediately put down Kuaizi and went out to contact them.

What came this time was a convoy. The so-called convoy consisted of only a few cavalry escorts and a carriage. When the carriage was opened, the cover of the carriage was revealed to be half a wine jar.

Li Mengxi beamed with joy when he saw the wine. Papermaking technology has advanced to the stage of decolorizing plant fibers. Although activated carbon can absorb pigments in carpenters, it cannot remove pigments in fibers. It is also known that alcohol can extract pigments. I am short of wine to test it. Well, just in time, the wine has arrived.

Li Mengxi took a jar of wine from the car and was about to open it to see how strong the wine was. This is when he found a small cloth strip taped to the wine jar with words written on it. When he saw it, it was "with Zhang". fly".

This chapter is not over yet, please click on the next page to continue reading! Li Mengxi smiled.

I understand, this wine was specially left for Zhang Fei by Liu Bei.

Well, this is Boss Fei. Liu Bei treats him like a child. He is thinking about giving some "snacks". He didn't say anything when he gave the snacks, but he was afraid that others would steal them, so he wrote specially.

At this time, Zhang Fei was out hunting. Anyway, prey was brought back from time to time, but he didn't know where Zhang Fei had gone.

Li Mengxi called a messenger cavalry and said, "Take a few people and call the three generals back. Tell them that Zhuozhou has sent wine for him."

Li Mengxi felt that if Zhang Fei heard that there was wine, he would have rushed back all night.

After counting the wine from Zhuozhou, excluding the wine clearly addressed to Zhang Fei, there were more than forty jars of wine left without any writing.

Since there is no writing on these unwritten wines, Li Mengxi will not give more to Zhang Fei. Wine is so important. High-level alcohol is a life-saving thing. One or two alcohol can save a life.

Now that the wine is available, the papermaking process that has been delayed for several days can continue.

He took half a cart of wine to the wounded barracks and found Tian Bu, the military doctor. Li Mengxi said that there was wine and he could steam some more alcohol. Tian Bu nodded and went into the tent to take out the still.

When Li Mengxi saw the small still, he suddenly remembered that although the hastily made still could be used, the distillation efficiency was extremely low, and a serious distillation method should have been used long ago.

The distiller used in the soju industry in later generations was probably a large copper pot with a double-layered lid. Water could be added inside for cooling, which was extremely efficient.

Thinking of this, Li Mengxi smiled and said to Tian Bu, "Tian Bu, do you want to know the method of making money worth thousands of dollars?"

Tian Bu asked with a smile, "If the military advisor wants to tell someone, then someone wants to know. If the advisor doesn't want to tell, then someone doesn't want to know."

Li Mengxi laughed loudly, "Let's go! I'll do this to you."

If we want to make a real wine pot, fortunately, we have recently made an iron pot and a stove. With the pot, we also have a stove. The only thing missing in the distillation process is the pot lid.

Li Mengxi took Tian Bu to the blacksmith camp. The camp was extremely busy at this time. The blacksmiths were busy forging plows. After calling the leader of the craftsmen, Li Mengxi asked, "Is anyone still idle?"

The leader of the craftsmen hesitated for a moment, "They are all busy. Is there any work?"

Li Mengxi nodded and said, "Yes, I want to find someone to make a pot cover, but if they are busy, forget it."

The leader of the craftsmen stopped him and said that making the pot cover would not delay the work, so he could do it together.

According to Li Mengxi's vague memory, it seems that the soju pot uses a copper lid. Is this because the copper lid is not easy to rust, or because the copper lid has strong heat transfer ability, which is conducive to cooling and condensation, or because the copper lid steams

I don’t know if the wine produced will be more mellow.

But thinking about it, the price of copper is very high after all. If the distillation effect of copper pot lids is no different from that of iron pot lids, then why would later brewing craftsmen not use iron ones instead of copper ones? Therefore, since copper is used, there must be other benefits.

It stands to reason that a copper still must have its magical uses.

In need of copper, Li Mengxi went to the warehouse to look for it. Fortunately, Liu Bei did not take all the money away, and there was still some left.

It is said that in addition to copper coins circulating among the people, there are also pure copper ingots that are less circulated.

The "bounty of five hundred hangings" mentioned in the Qin and Han Dynasties mostly refers to five hundred pure copper ingots.

Copper coins are not pure copper, they are made of alloy bronze, mixed with lead, tin and other substances, and the value of extremely pure copper ingots can be imagined.

Li Mengxi found several large baskets of copper ingots in the warehouse.

He didn't know how much copper it cost to make a pot cover, so Li Mengxi simply asked someone to carry a basket away.

At the blacksmith camp, when the craftsmen saw a large basket of extremely fine copper ingots being carried, the blacksmiths' eyes widened.

Li Mengxi pointed to the basket full of copper and said to the leader of the craftsmen, "Use this copper to make a copper pot lid.

If necessary, the pot cover must be double-layered, with openings at the top and bottom, so that water can be poured into the pot at the top and water can be drained from the bottom.

Also, the pot lid must have a spout-like proboscis to condense water.”

After explaining the structure of the still pot to the blacksmiths, Li Mengxi left. He had to modify the stove. An ordinary stove was not suitable for distillation because it lacked a pot that could seal the water.

along.

After Li Mengxi left, a group of blacksmiths put down their work and gathered around. They picked up copper ingots from the basket and weighed them with enthusiasm. A group of poor blacksmiths had never seen so much property. They had a huge fortune in front of them, and it was fun to touch it.

Seeing this situation, the leader of the blacksmiths immediately shouted coldly and drove all the craftsmen back.

The military advisor sent a large basket of copper without checking it. The military advisor had such trust in the craftsmen that he could not commit theft.

The leader of the craftsmen looked at the copper in the basket, glanced around cautiously, then roughly calculated how much copper was needed to make a pot lid, picked up seven or eight copper ingots from the basket, wrapped them in the hem of his clothes, and then called another one

The familiar blacksmith helped look at the remaining copper, and then went to arrange the matter of melting the copper and casting it.

There is an error in this. The logic of the blacksmiths' work is as always based on the habit of saving materials for the master. When they came to the army, although iron, firewood, etc. were not supplied as much as possible, the atmosphere in the craftsman camp was really

Well, it is really relaxing and comfortable. The craftsmen only regard the craftsman camp as their home.

The problem is here, when you work with the master next to you, you can help the master save as much as possible. When working in the craftsman camp, the craftsmen will be more willing to save as much as they can.

In such a province, something went wrong.
