From Chief to Ball

"After your labor reform is over, think about how to build a good farm. Use this template to submit it. The Department of Planning and Statistics approves it and thinks it is feasible. Then you are truly qualified to manage the farm. At that time, your labor reform will be considered to be truly over. .”

"You all know how to read, and you know a lot of characters. Let's see for yourself."

There was a sound of flipping through the wooden slips below, and Manyuan opened it and read it carefully. Although there was no expression on his face, he agreed in his heart.

Just like Chen Jian taught these people how to write plans before, the contents on the wooden slips are divided into four parts.

First, I wrote about the basic situation of the farm, including the number of people, nearby properties, and so on.

Then put forward the idea of ​​building a brewery, and the reasons for the construction of the brewery: to reduce the import of corn wine, and at the same time distribute it as a ration to the free slaves at the bottom, lest they smoke hemp leaves or gather crowds to make trouble; the fermentation residue after brewing Pigs can also be raised to feed dogs, and even distilled and exported to other cities.

Finally, there are the number of people in the workshop, the output, the various tools needed and the people who can make wine. This aspect needs to be reviewed by the Planning and Statistics Department, and then some people will be allocated.

There is not much planning, only the winemaking workshop, and it is very clear, to take advantage of the special situation of lack of farm tools this autumn and the lack of delivery of cattle and horses, so as to prevent the people in the farm from being busy in the field.

"Have you read it yet?"

"finish watching."

"Xiacheng used acorns to make wine and fruit to make vinegar. You all drank it too. Yes, it was made from the grains you drank in the past two years, but it's not like you just forgot about it in just two years, right? So many acorns, deer, fish, you can't see it? Or can't you think of it?"

"You have been working in the farm for a month, and you know everything about the farm. You are given two days to rest and take a bath to let you think about these things. After writing it, ask someone to send it back to the Department of Planning and Statistics, and I will personally Look, let's see if you have the ability to manage so many people! If not, then I can't help it, I will reform for three years at most, if you don't think about it within three years, it will only prove that you are not suitable to be officials."

Chen Jian put away his copy of the wooden slip, handed it to Ji Bai and said, "Look for someone, send it back to the Planning and Statistics Department immediately, let them review and approve, and prepare manpower."

Seeing that it was still early, Chen Jian spread his hands and said, "Today is not the end of the ten-day period, and it is not time to rest. I have prepared all the tools for you. Go dig the ditches. Ji Bo, send them there!"

A group of people reluctantly took the tools and stood with the disheveled farmers, bending down to dig this meaningless canal.

When it was not too late at night, the black-clothed guard who delivered the letter had already returned, carrying the approval from the Planning and Statistics Department, with a circle drawn in ocher on it, expressing his consent, and the tools and people who knew how to make wine would be mobilized within two days.

Chen Jian mobilized the farmers of the village community, tidied up a large house near the creek, and sorted out the necessary stoves, warehouses, and cellars.Some of the people who were digging the canal were conscripted to collect acorns.

Two days later, two Chinese people who can make wine came to the village with four or five apprentices and various tools. They collected a lot of wild fruits and acorns. I am no stranger, and I have also made it clear which one needs to use koji and which directly adds yeast—acorns need to be added with koji to break down sugar, while wild fruits are directly added with yeast.

In fact, there are still many things that can be done near the farm, and a winemaking workshop does not require many people, but Chen Jian did not bring up all of them. He gave those people the opportunity and hoped that they can grasp it.It is impossible for me to be comprehensive and take care of everything, and ultimately rely on these officials, otherwise, even if I am exhausted, I will govern at most thousands of people in a city.

After looking at it for a while, he returned to Yucheng without waiting for the completion of the work here. He believed that the people here would do a good job in this matter.

The construction of Yucheng is still in progress, but the smelting department with the largest number of people is still doing the work that the construction department should do, and Chen Jian is not in a hurry.

To build an iron smelting furnace requires a lot of preparatory work, and even if it is smelted, it cannot be mass-produced before everything is ready.

The most basic bricks and stones that can withstand the temperature of iron smelting have not yet been produced, and a canal has been dug near one of the two brick kilns to produce refractory blue bricks mixed with clay and white sand—different from red bricks, blue bricks require After the firing is completed, it is watered and cooked by steam. The production cycle is very long, but it is very strong and heat-resistant.

In addition, the bellows are still being manufactured; the small waterwheel, which cannot provide the pulling force of the bellows at all, has been completed and is being assembled to prepare for a larger waterwheel in the future; the prototypes of the crank connecting rod and the crank slider are still unimagined. come out.

The only thing that figured out was the acorns, but they were useless.

Because the earliest pottery wheels in Xiacheng were driven by belts, Acorn’s brain seemed to be tied by a belt. He told Chen Jian about his idea: prepare two pottery wheels with extremely small radii, connected by belts, Tie the handle of the bellows to the belt.Because the radius of the potter's wheel is extremely small, the point where the belt is tied to the bellows can be regarded as a rope that reciprocates back and forth, ignoring the radius.

The form of the belt drive can be regarded as the shape of two U-shaped butt joints. The acorn means that the distance between the two legs of the two U-shaped shapes becomes smaller, so that it approaches a line.

In fact, the idea of ​​this method is correct, even beyond Chen Jian's imagination. The problem is how can the friction between the belt and the pottery wheel be greater than the force of the bellows?It is feasible to change it to a gear chain transmission, but if Xiacheng can make a chain now, why bother to think about these problems.

Facing Acorn's disappointment, Chen Jian gave a few words of encouragement, but in his heart he admired that approaching thinking.

Acorns come from the belt drive that has been in contact for too long, and it is difficult to imagine it. However, this way of thinking made Chen Jian think of a way.

He still decided not to come up with the method he had thought up directly, but to use the small water wheel he made to do another thing, to give a little inspiration to the acorns, and at the same time save some manpower for the dyeing workshop to prepare winter clothes.

A hydraulic hammer with two simple connecting rods was his plan, a crank-rocker mechanism in mechanical terms.

In layman's terms, it is the pedal structure of an old-fashioned sewing machine, or the hand-cranked stepper on the simple fitness equipment in the previous life community.

Step on the pedal up and down, and the big wheel of the sewing machine can be rotated through the crank rocker structure. Here, it is nothing more than the reverse, and the rotation drives the rocker to make an arc-shaped fan movement, resulting in a reciprocating smashing effect.

This idea is actually in the same line as the crank slider, one is arc swinging, and the other is straight reciprocating.

Among them, the most critical idea of ​​conversion Chen Jian thinks that Acorn may be able to figure it out: use some method to extend the radius of the arc fan of the joystick infinitely, while the length of the arc remains unchanged.Then this arc can be approximately regarded as the secant of this circle, just like an infinite sphere where you can't feel the arc.The arc motion naturally becomes an approximate linear reciprocation.

Of course, by simply rotating the rivets, the mechanics of this infinitely extended radius can be virtualized. It exists but does not appear in the physical structure of wood and copper. This is what Chen Jian wants to solve.

His expectation for Acorn is that he can come up with ideas according to the previous way of thinking, even if it is not practical.

Chapter 1 Don't Build Utopia

The tools needed for a simple rocker hammer are actually very simple, a few trees that are sufficiently hard and tough, a certain skill in carpentry, four large copper rivets, and a wheel that can rotate: water power, donkey pull, or even human pull will do.

The length of the connecting rod, the size of the hammer that can be driven after the loss of rotation force, etc., made Chen Jian's head grow bigger. He was bored in the room for two days and solved the calculus and vector equations that he hadn't used for many years. From the horror of being dominated by function limits and mechanics many years ago, to determine the optimal moment length and angle, and not waste the meager power as much as possible.

When Chen Jian walked out of the room with red eyes, his hair was messy and full of greasy, haggard as if made of mud.

Two of the best carpenters were caught by Chen Jian and told them the length of the wooden connecting rods to be prepared, where to drill holes, and where to wrap them with copper to ensure the strength of the most stressed places.

He took out a small number of brass ingots and asked the Chinese who had done casting in Xiacheng to melt them with the crucible method to make thick rivets. Anyway, there is coal now, and the melting point of copper is only [-] degrees, which can be easily achieved.Brass is not bronze, and its toughness is okay.

The rest of the carpenters who were temporarily free were arranged by Chen Jian to make a batch of weird bows, made of elm or mulberry, but they were extremely thick and long, obviously not for archery.

After it was finished, Chen Jian impromptu sang the woolen version of "Plucking Cotton" with a small mallet, and brought these slinging bows to the dyeing and spinning department. Rinse it with ash water to remove the grease.

The Dyeing and Spinning Department is the most profitable group in the workshop planning of Yucheng, and it is also the group that Chen Jian attaches great importance to. In the coming winter, a large number of winter clothes must be prepared.

Winter clothes are clothes, and naturally they cannot be separated from cloth.

There are two kinds of cloth, woven fabric with warp and weft, and non-woven fabric without warp and weft.Both kinds of wool can be made, it can be spun into wool or even woolen wool, which requires the structure of warp and weft; it can also be smashed into wool felt, which is the simplest without the structure of warp and weft, just like the fur on wild dogs. condensed together.

What will be produced this winter is a batch of woolen felts. Not to mention the simplicity of production, you can also distinguish noble treatment in different ways: he has never planned to engage in absolute egalitarianism.

The hand-rolled wool felt is used as a welfare ration for the old people above the eighth rank. The output of this kind of wool felt is low, but the thickness is uniform, soft and beautiful.

The wool felt made by the hydraulic hammer is used as the welfare distribution of the Chinese people above the [-]th rank. This kind of wool felt has a high output, but it is stiff and ugly and uneven in thickness.

The level of noble treatment does not mean that you are superior in personality, it just means that you have not worked enough and paid enough for the city, that's all.No matter how it is changed, the distribution of public property among Xiacheng people is still calculated according to work. Absolute egalitarianism is an outdated thing from the clan era.

Xiacheng, built on the ruins of the clan era and leaping forward, does not need to face the deep-rooted ideological impact of unequal bloodline inheritance rights.Thought is like a blank sheet of paper, and pen and ink are Xiacheng's production method and rights system.

The difference in this kind of noble treatment can be intuitively reflected: it takes five people to work for five days and 25 labors to roll the felt by hand, but it only takes two people and half a day to smash it out with a simple hydraulic hammer.The former can be called the crafts of this era, and the latter can be called the necessities of this era.

But before this difference, there is another process that is all the same, which is to play wool.

Any textile raw material must go through the process of flicking to spread out the fibers to form a crisscross interweaving structure, so that it can be made into felt or spun into wool.

This is a manual job. After the advent of iron, simple wool combs can be made. Simple elastic is no longer suitable for weaving wool and wool. Those who do this will also be called wool combers.

Physical fatigue, low salary, and insufficient technical content are tedious and repetitive labor that men are unwilling to bear, and women who can bear tedious and repetitive labor cannot do it.

From the history of Chen Jian’s previous life, it can be seen that this type of work is the hardest. When the first batch of carders went on strike and revolted, it was 70 years before the fall of Constantinople, and it was only after they knew about gunpowder. 40 years.
