The research subjects in the Academy of Sciences are very complex and very loose, and Chen Xu does not have a specific research direction and object, and now there are hundreds of craftsmen and craftsmen who let them study projects on their own according to their own interests, so almost all the people in the entire Academy of Sciences are not doing their jobs, and they are studying some strange things that ordinary people can't understand at all.

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

However, with Chen Xu's continuous teaching, with the continuous development of the experimental plant of the Academy of Sciences, papermaking, steel, cement, ceramics, glass, enamel, tap water, four-wheeled carriages, waterwheel mills, bearings and movable type printing and other new things continue to appear, the aimless research subjects and idleness of the Academy of Sciences have slowly changed, especially after Chen Xu described several methods of mechanical transmission and the experiment of two copper balls landing at the same time, the Academy of Sciences broke out with an unparalleled enthusiasm. Many people have begun to study in the field of machinery, especially for gear chains, etc., which are very interested, with the support of experimental factories, many studies can be carried out, especially for some machinery commonly used in daily life are constantly improving.

Among them, the most improved are bearings and coinage machines.

In the past, Chen Xu instructed the invention of the money casting machine is a fully manual hand pressure molding machine, which requires at least three people to cooperate, and can only die cast one coin at a time, but after many craftsmen and hemp rods, Gong Win trial and error improvement, now it has been able to carry out simple linkage hot die-casting molding, the application of the drum driven, melted copper juice poured into a guide trough, the rotation gear to drive the drum forward movement while slowly cooling, semi-solidified state into a spiral cutting equipment and the manufacture of balls in the cutting and rotating into a ball, These balls fall into the coin, and then turn another handle, using the crankshaft and push the hammer to fall, you can die-cast the copper ball that is still in a high temperature state into a coin, and at the same time as the hammer is raised, a gear drives the rotating money fan to exit the die-casting area, and the other money fan is added, like a revolver movement, you can continue to carry out coin minting.

Although this machine requires four people to operate, one is responsible for pouring melted copper liquid, one is responsible for conveying and cutting balls, one is responsible for die casting, and one is responsible for removing the minted copper coins, but as long as the four people cooperate skillfully, the casting speed is more than ten times higher than before, and when the coins are minted, they hear the continuous sound of Ding Zero when the copper coins fall down the diagonal bucket and fall into the sink, and the four people can mint tens of thousands of coins a day.

The emergence of this new type of linkage mint machine made the speed of the Shaofu Mint Factory a lot faster, and made Shaofu Ling Zhao Wei feel less than half of the pressure on his body.

Since the monetary reform was agreed last year, nearly a year has passed, according to the emperor's requirements, at the end of this year, the implementation of the new monetary reform will be fully started, and in the future, the official rank and market transactions of officials will all use money, and the monetary function of grain and cloth will be abolished, of course, these are all official level, and the private transactions are not forcibly required, nor can they be forced, because the territory of Daqin is too large, 38 counties and more than 900 counties, and many places are still using all kinds of messy currencies of the first six countries, The main reason is that the number of coins circulating in the market is far from enough, so in remote counties and a large number of towns, it can only be slowly promoted.

At present, Shaofu and Huaxia Co., Ltd. cooperate, and the Mint Department exchanges a large number of minted coins with various old coins, and Huaxia Coin undertakes the delivery and issuance, and Shaofu gives a 5% subsidy.

This is a huge amount of income, according to the amount of coins issued by the Shaofu, within five years, the new currency will be issued at least 200 million yuan, and the money bank will make a profit of 10 million yuan, of course, part of which is the labor cost of transportation and promotion, but in the end it will not fall into the pockets of shareholders less than 5 million yuan.

According to Chen Xu and Fan Caiying's speculation, the issuance of 200 million yuan in five years is far from enough, and the final issuance number will at least triple, you must know that Daqin has a population of more than 20 million at the moment, and the issuance of 200 million yuan is only about ten yuan per person, what can ten yuan do, you can only buy a burlap, and the people do not have enough money in their hands, and getting rich is an empty word.

What's more, Chen Xu wants to vigorously promote commercial development, in order to drive the people to generate income, money is one of the biggest obstacles, merchants can use the exchange and deposit certificate transactions, but small merchants and hawkers and ordinary people must still use coins, because many places do not have Huaxia money, and the money village does not issue a thousand dollars below the bill, ordinary people do not believe and can not use the exchange ticket to trade, illiteracy is the biggest problem, and even most people do not know the numbers on the new coins, Coins can only be distinguished by their color, size, and shape.

Therefore, at the same time as the issuance of new coins, both newspapers and imperial decrees were publicizing the style and face value of the new currency to the counties, counties and towns, especially the officials of the townships and towns to post obvious explanations of the coins, so that the common people could understand them in advance.

In order to ensure an adequate supply of coins, the new minting machine was first researched and improved by Chen Xu and the craftsmen and craftsmen of the Academy of Sciences.

Although this linkage mint is still garbage in Chen Xu's opinion, all the people who have seen it were shocked by this efficient machine, and their first reaction was dumbfounded and speechless, especially Zhao Wei, who cried excitedly for half a night when he saw the new mint for the first time, but he didn't expect the Academy of Sciences to make this kind of magical machine, because a year ago, the Daqin Mint used the most primitive method of casting money with copper juice, and two people could only mint two or three hundred copper coins a day. And now that the shotguns are suddenly changing, one person can mint two or three thousand pieces a day, and the impact of the machine almost makes him feel like a dream.

At present, there are many innovative things to invent, such as semi-automatic printing machines, semi-automatic conveyor paper machines, and even looms, jacquard machines, and so on.

But these are not things that are urgently needed, just like bicycles, Chen Xu can only explain the principle, issue a reward, and let the craftsmen and craftsmen of the Academy of Sciences study and experiment by themselves, once the manufacturing is successful, it will improve the state of the entire industry, and it will also give birth to a number of new factories.

In the final analysis, it is caused by the fact that Daqin's industrial theoretical foundation is too weak and the industrial manufacturing technology is too backward.

Just a gear structure, now are still in the process of exploration, without the support of strict mathematical and geometric knowledge, to create a completely precise gear structure, it is completely impossible, at most is like a waterwheel mill as rough design, the operation process needs to be constantly adjusted, once one day mistake, gear occlusion error, the entire gear equipment will be scrapped, maybe the central shaft of the waterwheel will be torn.

It wasn't quiet in the Academy, with people coming and going in the various offices, and the voices of discussion and quarrel came and went.

When Chen Xu came, he happened to meet a craftsman and a craftsman who was arguing with a red face and a thick neck.

"Don't make any noise, Master Hou is here!" A scribe saw Chen Xu coming in and hurriedly reminded him.

"What are you arguing about?" Chen Xu walked into the office curiously, and found that there was a strange machine in the middle of the house that was all made of wood, with cranks, gears, and rollers, but he couldn't tell what it was at all.

"Master Hou!" The craftsmen and craftsmen hurriedly bowed together, while glaring at each other unconvinced.

"Master Hou, I designed a gear structure and asked him to help make it, he has to do it according to what I do, and he can't achieve the function I designed at the moment!" The craftsman complained angrily.

"Hou Ye Mo listened to his nonsense, the thing he designed couldn't run at all, the gears couldn't bite, how could the drum turn? So I changed it for him. "The craftsman is naturally not convinced, as an excellent craftsman with a high heart and pride, how can he tolerate this kind of low-level mistake that the drawings are not well drawn.

"You fart, my design doesn't need gears, and the drum turns itself when the mud passes by!" The craftsman jumped up and shouted.

"Okay, okay, don't make any noise, you tell me what your machine does, and I'll help you see it!" Chen Xu is also a head and two big, about the gear drum These things are new things that the craftsmen of the Academy of Sciences have recently come into contact with, and they are very interested, but there must be many problems in the design and manufacturing process.

"Master Hou, this is a pottery plate pressing machine made by me, you can put the stirred mud dough into it, turn the handle can press out the same thickness of the mud plate through the two rollers, I only need the upper drum to rotate, the lower drum is very small, you can rotate yourself under the extrusion of the soil, he added a gear to me when he built it, but the two gears do not fit well, it is extremely easy to get stuck and cause poor operation......," the craftsman pointed to the machine and said.

"Show me!" Chen Xu was immediately interested when he heard it.

This is a self-developed machine, which is of great practical significance.

At present, whether it is a pottery factory or a ceramic factory, the manufacture of clay blank plate is to make a large square clay brick first, and then cut it down layer by layer with a clay bow, but if the cutting is not well mastered, the thickness is uneven, and it will also cause the deformation of the clay board when taking and drying, and finally produce a large number of waste products, if this pressing machine is used, the probability of waste can be greatly reduced, and different patterns can be engraved on the drum, so that the surface of the clay tablet can be pressed out with different patterns......
