Rising: Ten Thousand Years Chapter 385: : The problem of cost

Li Zhen left.

After staying in Xizhou for a month and a half, I finally left Xizhou.

They left quietly, and only a few people like Xun Shifei knew in advance. But they didn't go to send them off, because Li Zhen refused, and they went to send them off, saying that they would come back. And will be back soon.

When Li Zhen got on the airship, the people in Xizhou knew why Li Zhen went back.

He wants to go back and develop a machine that replaces farming, adding fire to the country's food plan.

After the news came out, it quickly spread throughout the entire Western State at a shocking speed. Everyone knows.

"Dean Li said that he wants to develop a farming machine."

"What? Machines can be used for farming? How can machines be used for farming? Human resources are needed for farming. Can machines help cut rice?"

"It's impossible to think about it. When Dean Li researches these machines, the day lily will be cold."

"That's right. The machine is used to pull goods, and it is enough to replace mules and horses."

"Can machines replace cows? In paddy fields, cows can go, but machines can't."

"Are you so sure that Dean Li can't do research?"

"It's not to question Dean Li. It's just that this kind of thing is just a fantasy. Can the machine plant rice? Can the machine sow? Can the machine plow the land?"

"This time, Dean Li is a little whimsical. Sometimes science is really not applicable everywhere."

“…”

Including Xun Shifei is also suspicious.

Can Li Zhen really develop such a machine?

He couldn't help but think of the night when Li Zhen met him in Zhongzhou, when he said that he could start the mechanical age. But then, Xun Shifei figured it out, maybe it was just a young man's dream and wish.

Although now the Kyushu Academy of Sciences has played a huge role in various fields.

But sometimes we have to admit that science also has shortcomings. It doesn't solve all problems.

Perhaps, science can only be used in the military.

At least the Kyushu Academy of Sciences can make people fly and develop cars.

But, what else?

Actually, many people are relatively laymen on this point. Probably only those who really engage in science can understand that it can really play a role in various fields.

Because the original intention of science is to serve mankind.

It was born to solve problems that cannot be solved by manpower and bring convenience to people.

However, several major achievements have caused people to misunderstand. I think that maybe science is used at a higher level.

It cannot be used on ordinary people.

This is exactly wrong. It can be high-end or ordinary.

Whether everyone believes it or not, Li Zhen returned to Laoshan a few days later, held a meeting with the Kyushu Institute of Physics, and expressed his thoughts.

Li Zhen said: "First of all, we have to solve the simplest and most needed problem. It is to replace cattle."

"Cultivating land requires plowing, and cattle are limited. The workload of a cow is also limited. Many ordinary people cannot afford to use cattle to plow the land. What we need to do is to develop a completely replaced Cows, the workload is greater than that of cows, and they don’t know tired machines. Do you have any ideas for this goal?”

Li Zhen took a sip of tea and stopped talking.

Everyone was silent for a while, Ma Jianbin took a puff of his pipe, stood up and said:

"This is not difficult."

"Dean Ma has any ideas, let's talk about it."

"Ploughing the fields actually requires a forward power. Whether it is a steam engine, a two-stroke engine, or a four-stroke engine, it can replace the forward power. And we only need to add A plow. It is equivalent to developing a motor vehicle, and adding a plow to the rear of the vehicle can perfectly solve this problem.”

Li Zhen nodded: "You're right and very good. But you have to face a bigger problem. If it's a car, how can you move forward in the paddy field? It's a muddy pond. Do you have a solution for this?"

Another student from the Institute of Mechanical Engineering said: "This is not difficult. First of all, the speed of this plow machine does not need to be very fast. Then the speed is sacrificed and the power torque is increased, which is solved. Niu It is nothing more than four hooves that can step on the ground, so the movement is relatively flexible. As long as the power of the plow increases, even the wheels can move forward in the field.”

"To do this, in my opinion, four wheels are definitely not enough. Two wheels must be used to make the appearance of a cart. People walk behind, and the plow machine drives in front. People only need to use Just use the steering lever to control the direction. Of course, this wheel has to be special.”

"How special?"

"The rim needs to be big, so it has off-road performance. Only when you walk with big feet can you walk safely. The plow machine is actually not difficult. Master Li, please leave it to our Mechanical Engineering Institute, and we will be able to get the blueprint out tomorrow."

Li Zhen nodded: "That's good. The Mechanical Engineering Institute took the initiative to take the order, and the plow machine will be handed over to the Mechanical Institute for research and development. I only have one request."

Speaking, Li Zhen said seriously: "The cost should be low. As far as how low it is, the lower the better. It doesn't matter if it's simple, but it must be affordable for ordinary people. It must be lower than the price of a cow. .There is not much technical content, just two wheels and one engine, so you have to handle this yourself."

Better than the price of a cow.

The people in the mobile yard couldn't help but frowned again.

If you want to talk about the technical content of the plow machine, there is actually no technical content at all. It's just a driving force. But the cost is lower than the price of a cow, which is embarrassing.

How difficult this is ~IndoMTL.com~ You can see it with just one question. What is the price of the car? What is the price of cattle?

The cost of a four-stroke car is more than one thousand gold certificates, how much is a cow worth? Only two or three hundred gold coupons.

The core technology of the plow machine is the engine. But it happens that the cost of this engine is too high, how do you reduce the price? The Kyushu Academy of Sciences is not short of money, but there must be a factory to make it, right? The factory must make money. If the technical content is slightly higher, the cost will increase exponentially.

Li Zhen frowned: "Can it be solved?"

Ma Jianbin pondered for a long time, gritted his teeth and said, "Yes."

Li Zhen turned and said: "Plough machine, my plan is to introduce it in Xizhou first. There are not many, and every village can afford one. But the next step is a more difficult job, Xizhou The labor force is too small, mostly the elderly, and the labor force of the elderly is limited. So rice transplanting is also a technical job, do you think it is possible to develop a rice transplanter?"

Ma Jianbin and the others discussed it. Most of them were also born with mud legs, and they are no strangers to the farming work of transplanting rice seedlings. After discussing the principle of rice transplanting, I feel that there is no technical content in rice transplanting.

But no one dared to speak.

Because, since it is to be used for farming, the cost must not be high. Li Zhen must also say that the cost should be reduced.

Then this is not easy to handle. The core power of the rice transplanter is definitely the engine. If the engine cost of the plow machine is solved, the rice transplanter can also be solved.

The problem is that the rice transplanter is above the engine, so it definitely needs a lot of external facilities. A mechanical structure that replaces the action of human transplanting. These are not difficult, the people in the motor yard can draw a blueprint of a rice transplanter in just a piss.

The problem is back to the original point. It is still a matter of cost...
