More than a dozen villagers by the river in the distance are working hard to pick up water from the river to the paddy field, the paddy field is separated by an acre of land from the river, the distance is not close, Ji Xinyu looked a little anxious, turned to He Xingwang and said: "This problem of taking water can be solved by building a waterwheel, why no one has raised it." ”

He Xingwang managed too many things, so he didn't pay attention to this, at this time he also blushed a little, bowed down and said: "It's a lowly negligence, so I will arrange someone to do it." ”

He Xingwang found Lin Yuan, a carpenter from the palace, and asked him to call some carpenters to build a waterwheel, because now Ji Xinyu is not building a house based on wooden structures, and there are seven or eight of the more than twenty or thirty carpenters who are idle.

Ji Xinyu asked Aiden to draw a plan for a water canal, digging a main irrigation canal in the north and south directions of the field, digging a number of irrigation canals from east to west, raising the water wheels on the north and south sides to establish reservoirs, and reinforcing the irrigation canals and reservoirs with cement. Water is introduced into the irrigation canals from the north and south, and then brought to each paddy field by multiple east-west irrigation canals, which can be regarded as solving the problem of manual irrigation.

This is actually a very simple matter, but the manpower consumed is relatively large, and officials from all over Zhongzhou rarely arrange people to do this, and He Xingwang is also the inertial thinking brought by Bashu and does not pay much attention to the things in the field.

Ji Xinyu also asked He Xingwang to look for talents familiar with water conservancy among the villagers and displaced people, who were specifically responsible for water conservancy and agricultural affairs, and He Xingwang also knew that Ji Xinyu attached more importance to these things, so he immediately arranged for the posting of notices.

Looking at the busy carpenters, skillfully making the frame of the waterwheel with the trees cut down in the woods, Ji Xinyu had an idea: "Aiden, adding bearings to the waterwheel should improve a lot of efficiency." ”

Aiden replied, "Of course, but now the craftsmen are definitely not able to build it, and we need to make stainless steel bearings." ”

Ji Xinyu came to his own exclusive warehouse, and soon Aiden finished the two bearing parts, and Ji Xinyu assembled them. The diameter of the bearing is about 80 cm, and there are several screw holes left in the outer layer, and the matching screws are also held in Ji Xinyu's hands, which looks rough and exquisite.

Ji Xinyu found the guards, moved the bearings to the working carpenter, found Lin Yuan and handed the bearings to him, and asked him to lead someone to install the bearings on the central shaft first, the carpenters next to him looked at the bearings with a blank face, and Lin Yuan struggled to hold the bearings, and his eyes were also puzzled: "Young master, what is this?" Is this going to be used as the axis of the waterwheel? ”

Ji Xinyu didn't explain much, nodded and said: "This is a 'bearing' that can make the waterwheel spin faster." ”

Ji Xinyu was about to turn around and go back to his residence, when a guard came to report that there was something new in the arsenal and asked Ji Xinyu to check it out.

As soon as I entered the steel workshop, I saw Ushiya and several craftsmen circling around a frame made of steel pipes, and the bearing at the top of the shelf was constantly turning. Ji Xinyu opened his mouth and asked, "Niu Gu, what did you make?" ”

"Young master, the bearing has been made a long time ago, but the suspension system you gave, we only made it today, and we will let people report to you as soon as it is done." Niu Gu raised his head and said with a simple smile.

Ji Xinyu also circled around the front suspension system of the carriage, picked up a few bearings on the table, compared the two bearings, and looked very close in size, and said with a smile: "Not bad, it's made so quickly, and the gears are also made." ”

"Young master, the gears have been made a long time ago, and the brothers have made dozens of them, I don't know if they can meet the requirements of the young master." Ushiya took out a wooden box under the table, which was full of made gears and wiped with grease, apparently the craftsmen were like treasures.

"Okay, good, I'll test the effect of these things in a moment, and then I'll give you the task of making springs." Ji Xinyu took out a few more drawings and said that he wanted Niu Gu and others to slowly understand various steel processes in order to better complete the follow-up mechanical production.

Niu Gu walked forward quickly to take the drawings, and said excitedly: "The young master has something new for us to make, it's really good, my old cow has never made so many fine objects, these days are too addictive, the brothers are very happy, thank you, young master." Several blacksmiths behind him even claimed to be.

As a military craftsman, I still have a great sense of accomplishment in processing fine parts, especially after worrying about food and clothing. Ji Xinyu gave them two kinds of springs, one is a coil spring, the other is a leaf spring, each of which has heat treatment, tempering and other methods, according to Niu Gu's technology, I don't know what it will look like.

Ji Xinyu looked at it briefly, asked the guards to carry the front suspension system, took a few bearings by himself, and then went out of the workshop, took the bearings and roughly turned around to test the resistance, and the result made Ji Xinyu very satisfied, in his opinion, it was very successful.

"It took them so much time to make such a rough thing, it seems that the spirit transmission needs to be done a few more times, if you are proficient in controlling the temperature, and the proficiency in your hands is improved, it is not difficult to make a few finer bearings." Aiden began to analyze.

"Can you really improve their proficiency and precision? I thought you were just reinforcing their memory! Ji Xinyu was scared.

"My spirit is transmitted to them not only the process, but also the experience." Aiden said emphatically.

Ji Xinyu said to Aiden with emotion in his mind: "Aiden, your skill is really amazing!" ”

"A lot of my old features are no longer available, and only these extras can help you." Aiden said with a look of grief.

Ji Xinyu smiled and wanted to comfort him, but he didn't know where to start, so he didn't speak again. And Ji Xinyu doesn't have to be Niu Gu how skilled they are, as long as they can understand the principle, he will need more than just manual skills in the future.

Back to his small courtyard, Ji Xinyu asked the guards to put down the front suspension system, took the bearings and began to study the four-wheeled carriage, the current carriages are two-wheeled, no bearings, no shock absorption, through the wheels with a different number of horses to pull and adjust the direction, such a carriage people ride the comfort is very poor, and the carrying of goods is also limited.

At first, Ji Xinyu only wanted to make a front suspension steering system, add it to the existing carriage to replace the wheel, after observing the whole carriage, he felt that even if he installed a carriage that could steer the front wheels, the bumps were still very strong, and the wooden structure of the car body was also very heavy, loading and carrying people would be a problem, and finally he decided to make a new one.

Let Aiden draw the drawings, Ji Xinyu found a blacksmith to start making it, because the frame didn't need to be too fine, so he didn't look for Niu Gu, but went to the blacksmith workshop to find an ordinary blacksmith with better skills.

The entire frame of the carriage is made of hollow steel pipes, which is equivalent to a square barrel that does not need to be polished, and the strength can still reach the standard after heat treatment, and the body is wrapped with thin iron sheets, and two half-meter-wide arc-shaped thick steel sheets are connected from the bottom to the front and rear, acting as shock absorbers and supporting the body.

In addition, the four corners of the front and rear of the carriage are added with thick steel sheets pressed into an olive shape to act as springs, which share the shock absorption pressure of the bottom steel sheets and are also more firm.

At the front of the body is a separate front wheel suspension system, which is connected to the body with bearings, and the axles and four wheels are also made of steel with additional bearings. Ji Xinyu does not have rubber yet, Aiden extracts a similar colloid from the resin, and after treatment, it is made into solid rubber tires, which can fully meet the needs of shock absorption and wear resistance after testing.

After the completion of the body, the body is equipped with a body of one meter eight and two meters long, two wooden seats are fixed on the front and rear compartments, and the seat cushion is a soft leather felt with filling, fixed on the wooden seats, and can sit four to six people face to face.

The doors are open on both sides and front and rear, and there are wooden baffles and curtains to shield them, and there are driver's seats in front of the body, as well as cushions with leather and cotton padding.

After five busy days, with the help of Aiden, the entire carriage frame was finally completed, and the whole vehicle was connected with screws and nuts, which was the first machine in Lingchuan Mansion to use a large number of screws. After the frame was completed, Ji Xinyu asked people to decorate the roof body with paint and wood carving, and the whole car was completed, which roughly looked like a wooden body, but in fact it was completely a steel structure.
