Doomsday Bunker Upgrade

For Chen Xin, in order to obtain enough supplies, in addition to the extremely inefficient and dangerous way of picking up trash by himself, obtaining supplies through Li Yulong is the easiest and most direct way.

Originally, the SWAT team was also a very suitable partner, but now the SWAT team's energy is focused on catching terrorists, and naturally there is no extra energy to deal with the material exchange with Chen Xin.

Chen Xin had also disclosed to the SWAT team that he wanted to exchange more supplies, but the reply he got was that it needed to be temporarily postponed.

This is obviously because the SWAT team has no way to allocate enough manpower to deal with this matter, so it can only postpone this matter temporarily. After the terrorist matter is dealt with, it will have time and energy to deal with the exchange of materials with Chen Xin. thing.

As a result, Li Yulong became the only channel through which Chen Xin could obtain supplies.

However, Chen Xin didn't show this. After all, it's not that the friends of other survival groups can't exchange materials, but the materials they can exchange are too few, and few people can reach his home to exchange materials with him.

After receiving Chen Xin's request, Li Yulong acted very quickly, and did not let Chen Xin wait for a long time to prepare the materials he needed and deliver them to Chen Xin's house.

In addition to the scrap tires that Chen Xin wanted this time, there are also auto parts that he and Li Yulong said before, which were used to transform his car.

"Brother Chen, I've brought you what you asked for!" Li Yulong still came over in person, greeted Chen Xin, and flattered him: "For the sake of our diligence, what you said Can you make me a pair of that snow track wheel first?"

Listening to Li Yulong's words, Chen Xin couldn't help showing a smile on his face, and smiled at him: "Your RV shouldn't need this, right? And with such a big wheel, the matching snow track wheels are not easy to do."

Chen Xin is not deliberately rejecting Li Yulong, just like he said, Li Yulong's RV itself has large snow tires, and the chassis itself is high enough, even in today's environment with more than one meter of snow on the road. It can also drive smoothly, and the demand for snow crawler wheels is not large.

And large tires, of course, should be equipped with large snow track wheels.

Compared with ordinary car tires, which may be the size of ordinary people's knees, Li Yulong's RV is equipped with tires that can reach people's chests. Such large tires need to be equipped with snow track wheels, and naturally they must be larger. .

But to increase the size, it is obviously not to say that it is enough to do it.

"How is it possible that this kind of thing is so difficult for you, Brother Chen?" Li Yulong was immediately flattered, and while flattering Chen Xin, he also said to Chen Xin: "I don't want to experience this thing first, whether it works or not. Well! If it is easy to use, this thing can also be a special product that we put on the market in the future, right?"

"Do you want to sell snow crawler wheels as a commodity in the trading market?" Chen Xin rubbed his chin after listening to Li Yulong's words, but he didn't object.

A trading market, in addition to providing a platform for other traders to trade, has its own unique products that cannot be copied by others, which is the key to attracting more customers and traders.

Originally, what Li Yulong prepared for the trading market was the ground source heat pump obtained from Chen Xin, which is naturally enough to attract customers, but who would dislike too many commodities that can make money in their hands?

At least Li Yulong and Chen Xin didn't think so.

So the two quickly concluded a new cooperation agreement, Li Yulong provided materials, and Chen Xin helped make snow track wheels.

And because Li Yulong felt that the technical difficulty of this thing was not very high, he also proposed that Chen Xin would teach his people the technique of making snow track wheels, and learn how to maintain them no matter how bad it is.

After all, snow crawler wheels are not the same as ground source heat pumps. Compared with ground source heat pumps, which do not require much maintenance after they are installed, snow crawler wheels are consumables that are easily depleted.

Although it does not mean that it is broken after one use, it is very normal to need to repair and replace worn parts after a period of use.

Especially Chen Xin uses rubber tracks, which obviously wear out and need to be replaced regularly.

Regarding Li Yulong's proposal to let him teach his subordinates, Chen Xin nodded and agreed after thinking about it.

However, Chen Xin did not say to teach them production techniques, but only agreed to teach them maintenance.

Although he felt a little regretful that Chen Xin did not agree to teach his subordinates manufacturing techniques, it was already very good to be able to master maintenance techniques, so Li Yulong did not feel any dissatisfaction, and readily agreed to this matter.

Not only that, Li Yulong also followed Chen Xin enthusiastically, wanting to see how he built the snow crawler wheel.

Chen Xin didn't mind Li Yulong's actions by following him. After his subordinates moved the supplies and materials into his storage room, Chen Xin also sat in front of the workbench, preparing to make the first pair of snow. Track Wheels.

Ding Ning and Qin Lan, who were temporarily staying here, naturally surrounded him for the first time, curious to see how Chen Xin made things.

Facing the onlookers of three people, Chen Xin didn't care, and directly used the system interface to transfer a waste tire from the warehouse, and started the transformation.

In the system interface, a waste tire that had been ground with grooves was quickly melted, then re-deformed and woven into a new shape together with the inner lining steel wire, and a rubber track component soon appeared. On Chen Xin's workbench.

Chen Xin could naturally see how the waste tire was turned into a track assembly, but in the eyes of the three onlookers, Ding Ning, Qin Lan, and Li Yulong, what Chen Xin saw was how Chen Xin cut a waste tire, and then Flattened, cut to a suitable size, and then finely processed into track assemblies.

"Brother Chen, your hands are really clever! A piece of waste tires can be used in your hands!" Li Yulong couldn't help but exclaim, and even Ding Ning and Qin Lan on the side couldn't help but agree.

Chen Xin didn't care about the three people's praise, and said to Ding Ning, "Xiao Ding, help me get the parts made over there."

Hearing Chen Xin's order, Ding Ning naturally helped Chen Xin to bring over the parts he had made before and put them in front of Chen Xin.

In addition to the track itself, the components of the track structure also include driving wheels, road wheels, idlers, and idlers. The driving wheel is a mechanism that transmits power to the track through the meshing of gears and track teeth.

However, the snow track wheel made by Chen Xin is just a track component and does not require the driving wheel to provide power, so he did not design this part on the snow track wheel, only the road wheel, the idler wheel and the idler pulley.

The road wheel, as the name implies, is used to carry the load and straighten the track; the idler wheel is responsible for inducing and supporting the track, and the idler wheel is used to support the upper track.

In addition, although there are many supporting parts, the snow crawler wheel is not a tank crawler after all, and the structure is not so complicated, so it is much simpler to make.

As long as these wheels are assembled to the already made brackets, then the track assemblies are assembled, installed on these wheels, and finally the fixed assemblies are installed, and a snow track wheel is ready.

Looking at the completed snow track wheel, Chen Xin felt that this thing looked really rough.

But it doesn't matter. After all, the crawler itself is associated with the impression of being stupid and black. As long as it is easy to use, it doesn't matter if it is a little rough.

And this is also the consensus of Ding Ning, Qin Lan and Li Yulong who are watching by Chen Xin.

As long as it's easy to use, why bother if it's rough or refined?

In this apocalypse, if you have to investigate whether something looks good or not, it can only be said that you have a bad brain or you are too full.

"Brother Chen, is this the snow crawler wheel? How does this thing work?" Li Yulong looked at the snow crawler wheel made by Chen Xin and asked him curiously.

Chen Xin tapped the snow track wheel assembled in front of him, and explained to the three people watching behind him: "Through a pad, let the wheel fit into this slot, and then fix these fasteners to ensure that this thing will not slip off. After that, only the wheels need to be rotated to drive the transmission mechanism, and the track wheels can be moved to drive the vehicle forward."

"Wow, isn't that very convenient?" Ding Ning exclaimed in admiration.

Chen Xin nodded slightly: "Although in terms of transmission efficiency, it is not as powerful as directly removing the wheels and replacing the track structure, but in terms of ease of use, this kind of snow track wheel is much more convenient, and it is necessary to use Putting it on when it’s not in use and taking it off when it’s not in use is a lot easier than changing the wheels.”

Listening to Chen Xin's introduction, the three onlookers couldn't help but nod their heads. They didn't understand anything. They could clearly distinguish the difference between directly changing tires and installing such track wheels, but it was obvious that Chen Xin did. The track wheel that came out is obviously more suitable for use now.

After all, most vehicles are still wheel structures. If you want to remove the wheels and replace them with tracks, the replacement process is not only cumbersome and troublesome, but also requires professional technicians to operate. How can such track wheels only need to be placed on the ground, and then drive the car. Is it easy to go up?

Seeing the production of the first track wheel, Li Yulong couldn't wait to say to Chen Xin: "Brother Chen, make the other three as well, let's install it and try it out!"

When Chen Xin heard what he said, he nodded and said to him, "Go and help me move a few more used tires."

Hearing Chen Xin's order, Li Yulong hurriedly ran to Chen Xin's storage room.
