The research subjects in the Academy of Sciences are very complex and very loose. Chen Xu does not have a specific research direction or object. Now he has hundreds of craftsmen and craftsmen to study their own projects according to their respective interests. Therefore, almost all the people in the Academy of Sciences are inappropriate people, and they receive generous salaries every month, but they are studying some strange things that ordinary people cannot understand.

When the Academy of Sciences was just established, many craftsmen and craftsmen were almost exhausted all day long, reading books, newspapers, playing chess, tea and chatting, waiting for Chen Xu to arrange tasks for them.

However, with Chen Xu's continuous teaching and the continuous development of the experimental factories of the Academy of Sciences, new things such as papermaking, steel, cement, ceramics, glass, enamel, tap water, four-wheeled carriage, water wheel mill, bearings and movable type printing continue to appear, the Academy of Sciences' aimless research subjects and idle state gradually changed. In particular, Chen Xu talked about several methods of mechanical transmission and experiments on two copper balls landing at the same time, the Academy of Sciences burst out with an unparalleled enthusiasm. Many people began to conduct in-depth research in the field of machinery, especially with great interest in gear chains, and with the support of experimental factories, many research can be carried out, especially for some commonly used machinery in daily life, which is constantly being improved.

Among them, the biggest improvements are bearings and coin casting machines.

The money casting machine invented by Chen Xu in the past was a fully manual hand press forming machine, which required at least three people to cooperate, and could only die-cast one coin at a time. However, after repeated trials and improvements by many craftsmen and hemp rods, Gongshusheng, it is now possible to perform simple linkage hot die-casting. Driven by rollers, the melted copper juice is poured into a guide groove, and the rotating gear drives the drum forward while slowly cooling. The semi-solidified state enters a spiral cutting equipment that makes the balls cut into pieces and rotates into balls. These balls fall into the money range, and then turn another handle, and use the crankshaft and push rod to push the hammer to fall, and then die-cast copper balls in a high-temperature state can be die-casted into a coin. While the hammer is lifted, one gear drives the rotating money range to exit the die-casting area, and the other coin is added. It moves like a rotary pistol, and coins can be continuously cast.

Although this machine requires four people to operate, one is responsible for pouring melted copper juice, one is responsible for teleporting and cutting balls, one is responsible for die casting, and one is responsible for taking down the casting coins, as long as the four people cooperate with each other, the casting speed is more than ten times higher than before, when minting coins, the sound of the copper coins falling down along the slanting bucket and falling into the sink. Four people can coin tens of thousands of coins a day.

The emergence of this new linkage coin minting machine made the Shaofu coin factory much faster, and made Shaofu Ling Zhao Wei feel that the pressure on his body was half reduced.

Nearly a year has passed since the agreement on currency reform last year. According to the emperor's requirements, new currency reforms will be fully implemented by the end of this year. In the future, all officials' official rank and market transactions will be used in coins, and the monetary functions of grain and cloth will be abolished. Of course, these are all about the official level. There are no forced requirements for private transactions, and they cannot be forced, because the territory of the Qin Dynasty is too large, and more than 900 counties, and many places are still using various messy currencies from the first six countries, mainly because the number of coins circulating on the market is far from enough. Therefore, they can only be promoted slowly in remote counties and a large number of towns.

At present, Shaofu and Huaxia Money Bank cooperated to exchange a large number of minted coins with the money bank for exchange of various old coins. Huaxia Money Bank undertakes transportation and issuance, and Shaofu provides a 5% subsidy.

This is a huge income. According to the amount of coins calculated by Shaofu, within five years, the new currency will be issued at least 200 million yuan, and the bank will make a profit of 10 million yuan. Of course, part of it is labor costs for transportation and promotion, but the end of the money will not fall below 5 million yuan.

According to Chen Xu and Fan Caiying's speculation, issuing 200 million yuan in five years is far from enough, and the final number of issuances will at least triple. You should know that the current population of Daqin is more than 20 million. Each person has only about ten yuan for issuing 200 million yuan. What can ten yuan do? He can only buy a piece of burlap. The people do not have enough money, and getting rich is just empty talk.

What's more, Chen Xu should vigorously promote commercial development to drive the people to generate income. Money is the biggest obstacle. Merchants can trade vouchers and certificates of deposit, but small merchants and ordinary people must still use coins, because there are no Chinese currency banks in many places, and money banks do not issue vouchers less than 1,000 yuan. Ordinary people do not believe it or cannot use vouchers to trade. Ignoring literacy is the biggest problem. Most people do not even recognize the numbers on new coins, and can only distinguish them by the color and size of the coins.

Therefore, while issuing new coins, both newspapers and imperial edicts are promoting the style and face value of new currency to counties and towns, especially asking township officials to post obvious coin explanations so that the people can get to know them in advance.

In order to ensure sufficient supply of coins, the new coin minting machine was first developed by Chen Xu, a craftsman from the Academy of Sciences, who first asked the craftsmen of the Academy of Sciences to study and improve it.

Although this linked coin minting machine was still rubbish in Chen Xu's opinion, everyone who had seen it was shocked by this efficient machine, and his eyes fell to the ground. His first reaction was that he was dumbfounded and could not speak. Especially Zhao Wei, when he first saw the new coining machine, he cried for a long time. Unexpectedly, the Academy of Sciences could still make such a magical machine, because a year ago, the Daqin Mint used the most original method of minting copper juice to pour money style. Two people could only cast two or three hundred copper coins a day. Now, they suddenly replaced the cannons, and one person could cast two or three thousand coins a day. The impact brought by the machine almost made him feel like he was dreaming.

There are many things to invent and innovate now, such as semi-automatic printing machines, semi-automatic conveying paper machines, and even looms, jacquard machines, etc.

But these are not important things. Just like bicycles, Chen Xu could only explain the principles and give rewards to the craftsmen and craftsmen of the Academy of Sciences to study and experiment on their own. Once the manufacturing is successful, the status of the entire industry will be improved and a number of new factories will be produced.

After all, it is because of the weak industrial theoretical foundation of Daqin and the backward industrial manufacturing technology.

Just a gear structure is still constantly exploring. Without the support of strict mathematical and geometric knowledge, it is completely impossible to create a fully precise gear structure. At most, it is a rough design like a water wheel mill. It requires continuous training during operation. Once one day the error occurs and the gear choke error occurs, the entire gear equipment will be declared scrapped, and it may not be uncommon for the central shaft of the water wheel to be twisted.

The Academy of Sciences is not quiet, and people are coming and going in and out of each office, and discussions and quarrels are heard one after another.

When Chen Xu came, he happened to meet a craftsman and a craftsman who was quarreling with him, blushing and thick neck.

"Don't make a noise, the marquis is here!" A civil servant saw Chen Xu coming in and reminded him immediately.

"What are you arguing again?" Chen Xu walked into the office curiously and found a strange machine made of wood in the middle of the house, including a shaking handle, gears, and rollers, but he couldn't tell what it was.

"Mr. Marquis!" The craftsman and the craftsman quickly bowed together, and at the same time stared at each other dissatisfiedly.

"Mr. Marquis, I designed a gear structure and asked him to help me make it. He had to do what I had done. At present, the function I designed was completely impossible!" The craftsman complained angrily.

"Mr. Marquis, don't listen to his nonsense. The thing he designed cannot operate at all and the gears cannot be bitten. How can the roller turn? So I changed it for him." The craftsman was naturally not convinced. As an arrogant and excellent craftsman, how could he tolerate such low-level mistakes that could not even draw drawings well.

"You fart, my design doesn't require gears. When the mud passes by, it can be squeezed and rotated by itself!" The craftsman jumped up and shouted.

"Okay, okay, don't make noise. Tell me the function of your machine, and I'll help you see!" Chen Xu was also one of the top two. He was very interested in gear rollers and these things were new things that craftsmen from the Academy of Sciences. However, there must be many problems in the design and manufacturing process.

"Mr. Marquis, this is a ceramic plate pressing machine I made. You can put the stirred mud balls in. Turn the handle and press the mud plates of the same thickness through two rollers. I just need the drum above to rotate. The drum below is very small and can rotate by itself under the squeeze of soil. He added a gear when he built me, but the two gears were not well matched, which was extremely easy to get stuck and caused poor operation..." Jiang Jie Li pointed to the machine and said.

"Transfer it to me!" Chen Xu became interested immediately as soon as he heard this.

This is an independent research and development machine and is of great practical significance.
