Chapter 46: The completion of the water diversion canal (Spring Festival update 25)
The problem was found, and the improved model was immediately developed. The main thing was to lengthen the wheel center and be more careful when drilling the axle hole. The smaller the error, the more stable the car will be, and there will be no wobbling.
Another problem is to increase the number of springs. It is not that Luo Chong is unwilling to increase the number of springs, but there is no lathe now. If you want to make a few springs, you can only rely on chopping with a knife and chiseling. The speed is too slow, which has become the slowest link in the wheel production, and it is impossible to guarantee the quality of each one.
Later, Luo Chong simply gave up making his own springs and directly used the spikes of the man-eating tree, that is, using arrow shafts as springs.
However, that thing is relatively thin, so the number can only be increased to improve the supporting capacity. This is still inspired by the bicycle wheel. The spring of the bicycle is thinner, similar to the iron skewer for barbecue, but there are at least hundreds of such thin springs on a bicycle wheel, which can support two people.
So the production speed of the second car was much faster. Although the number of springs increased to 32, they were all natural wooden poles, and they could be installed as long as they were cut into the same length.
The speed was increased, but the support force was not enough. The arrow shaft was only about 1 cm in diameter, which was used to support the wheel structure. It was OK when the car was empty, but it was not good after loading heavy objects. It was relatively thin and not strong enough. However, the wheel center of the second car was very successful and never shook again.
When it came to the third car, the wheel became a double-layer spring. The number of springs of a wheel directly increased from 32 to 64, forming a double-layer structure connecting the wheel center and the outer ring. The effect was naturally as good as it could be.
So the third car was determined to be a mass-produced model and began to be mass-produced. The first batch of 30 cars was made. Now, there must be dozens of adult laborers, including men and women. This kind of ash bucket car is specially used to pull soil. It will definitely be used in large quantities in the future, especially when ramming the city wall. Now make more to be prepared, and also to accumulate experience for making larger cars.
The spikes of the man-eating tree are inexhaustible. A lot of them will fall off if you turn around under the man-eating tree with a straw target on your head.
The carpenter work is still done by three people for the time being, but the most troublesome clockwork step is saved, and the speed of making carts is still very fast. The engineering team is equipped with three carts in two days.
With the ash bucket cart, bronze shovel, giant plow, and two cute babies who love to step on mud, the first phase of the water diversion project is also progressing rapidly. The brick-making work that had previously slowed down the progress has also been accelerated because of the carts.
It was not until the 18th day of the start of construction that a long ditch with a length of 700 meters and a minimum depth of 4 meters appeared in front of Luo Chong.
Luo Chong was naturally overjoyed, as he himself did not expect the progress of the project to be so fast. It's just that the tribesmen don't know why this long ditch is dug. Most of them just think that Luo Chong is digging the soil for those mud blocks, but they don't understand Luo Chong's real purpose.
After all, the current water diversion river still has two meters to be dug through the small river, and there is no water in it now, so in the eyes of most people, it is just a deep ditch.
Although the Han tribe is not short of food now, the tribesmen still have complaints about Luo Chong's arrangement of not gathering food and digging the soil to make mud blocks every day. The people of the original Xieding tribe are the most serious. Although they dare not object, they can't stop discussing it privately.
The people of the Han tribe naturally listen to Luo Chong unconditionally. They are accustomed to the strange things Luo Chong often does, and no matter what Luo Chong does, it will benefit the tribe in the end.
Luo Chong doesn't care about these at all. He thinks that any explanation is futile. If you tell a group of primitive people about farming, can they understand? They only care about whether there is food or not, and they don't think about anything else. It has nothing to do with food, so well, forget it.
In fact, it is also true. It was Luo Chong who forced this evolutionary process to be advanced. Otherwise, it would take many years for them to develop to the farming era on their own.
The normal history of human development should start with the mastery of fire. Eating cooked food can promote brain development. Later, humans mastered stone weapons and learned how to hunt in groups, which led to the extinction of wild animals. With less and less food to eat, humans had to find new sources of food.
During this period, humans learned to grow crops or raise animals to obtain a large and stable source of food.
However, humans who did not learn to grow crops and raise animals were submerged in the long river of human evolution. They either starved to death, were eliminated by nature, or were annexed by farming tribes and nomadic tribes, thus becoming one of them.
Luo Chong's tribe was still in an era without stone weapons and hunting. When they first came here, the hunting team was still chasing after the prey with sticks.
But this does not mean that the people here are stupid and cannot do farming and breeding. They just lack an opportunity for reform, and Luo Chong is that opportunity. So he has only been here for two months and has accelerated the process to the breeding mode. By next year, even rice will be planted.
Although the tribesmen do not understand Luo Chong's approach now, they cannot be blamed. They will see the results. Next year, they will all wear rabbit skin clothes, eat rice, fish and rabbit meat every day, hold bronze weapons in their hands, and go out to drive donkeys or horse antelope carts. At that time, I don't believe they will say that Luo Chong is not good.
The river digging work stopped completely, and the tribesmen returned to their normal life track. The men continued to cut wood. There was no fear of too much wood. In the future, whether it was building a city, making cars, ships, or building houses, a large amount of wood would be needed, and the wet wood that had just been cut could not be used. It had to be dried.
The women went to collect food again, and even went fishing. Luo Chong couldn't stop them. They thought that it was okay to not finish the food, but they must not eat less.
Since they had to find something to do, then go ahead. At worst, they would eat as much as they could in winter.
The construction of 30 carts was also completed. Now, under the guidance of Luo Chong, wooden barrels and wooden pigs were trial-making larger carts that could be pulled by horse antelopes to prepare for the large-scale mining of copper in the future.
The new carriage adopts the European four-wheeled vehicle shape. In the early ancient times of China and the West, there were two-wheeled carriages. The two long poles in front were hung on the horse's back. The carriage was very bumpy when it was moving, and it was a great burden on the livestock.
For a two-wheeled carriage, the livestock not only had to bear the force of pulling forward, but also the weight of the entire carriage. However, the four-wheeled carriage was different. Even without a horse, the carriage could bear the load by itself, and the horse pulling the carriage only needed to output the forward force, which directly reduced more than half of the burden.
In addition, because of the consideration of load capacity and service life, a large number of bronze parts will be installed in key parts of the new carriage.
Speaking of bronze, the ore Luo Chong brought back this time has been refined, and now there are more than 400 kilograms of copper and tin reserves, not including the weight of those that have been cast into objects. These more than 400 kilograms are all gold and silver plates.
These days, Luo Chong is also making bronze alloys, trying to make a plow for normal farming.
