However, although Haikou has been exaggerated, the structural principles of these parts cannot be integrated within a day. The structure of the fan car is undoubtedly a bit more complicated for today's mountain and sea carpentry industry.
Danzhu held his breath, said all the words, and hung his face on the door. If he can't get it out tomorrow, will he still have his name?
The fan car is a kind of grain cleaning tool, which generates airflow through the rapid rotation of the fan wheel to remove the chaff in the grain. The fan car is a speed-type centrifugal blower, and its working efficiency is much higher than that of fans and dustpans.
"Ji Jiu Pian" says: "íÔ³}, fan, ëP, pound, and winnow". To be honest, I know every word in this sentence, but when combined together, there is a feeling of not knowing
The semi-open fan car clamps the fan wheel between the two box boards, and the shaft is located at the middle height or placed on the top of the box. Later, a more advanced closed fan car appeared, which sealed the fan wheel in the box, and the air inlet was located at the top of the box. At the shaft, the airflow in the box conforms to the direction of centrifugal movement; the air outlet is shrunk to prevent the vortex backflow of the gas, and the dynamic pressure of the air outlet is increased to transport the chaff farther
Danzhu suddenly felt that this was a challenge to himself, and it was also an opportunity to prove himself.
The reason why Di Fangxun didn't like Danzhu's carpentry work, especially shipbuilding, was because in Fangxun's view, the sea was huge and the four seas were far away. It is just a humble worm, a wave can overturn the ship, and the ship that the adult country can manufacture is too small for the Central Plains.
What is the use? The land is so vast, and the products are also very rich, and the things at the door of the house have not been dealt with. If you learn from the adult country and go to sea, isn't this sick and looking for death?
Adults, if the national ship capsizes, people can still swim to the edge of Dongyi with bare hands, but if the people's boat capsizes in the Central Plains, there will be no more.
What are you doing running to the sea when you have nothing to do? It is enough for ships to cross great rivers! No matter how it is made, it is just a big piece of wood. What technical content does it have?
Gods who can fly don't need this thing, and people who can't fly don't need this thing. What's the meaning of this thing?
But Danzhu doesn't think so, the sea is very interesting, and even in big rivers, strong boats with high maneuverability can save many people in time.
Fan carts are also agricultural equipment that appeared in the Western Han Dynasty.
"There is a bucket in here Let me see"
Danzhu carefully studied the board and started to prepare the wood. He took out his own tools and began to knock in his residence. Of course, what surprised him was a thing in Yuzai's hand.
This is a new version of the clam sickle that I have never seen before! This is "saw"! ?
Enhancement plus 20? !
In Danzhu's opinion, this thing is no less than an epic artifact. As for the original stone clam sickle, it is a silver scale breastplate bought for two gold coins. It used to be very good, but now it is a bad product
"Ah Hongwhat are you doing"
Chi Songzi saw a bamboo sign hanging on the door.
"Don't disturb the controller?"
Chi Songzi immediately understood that it was probably Yuzai who had shown Danzhu something, and the two had already been in contact with each other this morning.
In the tribe, food is being transported to the barn. The barn is naturally built on a high ground, and the surrounding drainage canals have been done long ago. There are many times in a year, and many things do not need to be specially loaded. I told the clansmen to excavate these facilities in important places on the high ground after experiencing the convenience of the canals and ditches to prevent rainwater from soaking into the barn.
The tall barn stores a heavy amount of grain, and those empty stone jars can¡¯t hold it anymore. The old patriarch couldn¡¯t stop laughing from ear to ear. He didn¡¯t expect that the thirty large stone jars he dug before are now full. There is still more food, which is being stuffed in continuously!
"The number of chisels is still small! If I knew it, I would have chiseled more, but unfortunately there is not enough time!"
"Bring all the unfinished ones, make them shallower, and go back and chisel again!"
The old patriarch asked people to bring in the unfinished large stone jars that were still being smashed, and the grain was poured into it continuously. In the end, there was no other way but to get some soil to beat into an earthen platform, and put the animal skin bags full of grain into them. Stock up on it.
And the largest tank was made of several pieces of tortoise shells of the old tortoise, which can hold at least five thousand stones of grain!
Akakata's arable land is very large, and most of it is composted. For several months, everyone is farming in the field, and the stone ox pulls the plow tirelessly. Fortunately, there are so many factors together. In order to meet the work needs of so much arable land.
But even so, there is still a lot of land that is widely harvested and thinly planted. That is because it is too difficult to take care of it. up.
The tortoise shell tank is full of food from the land plowed by the dolphins. It is so full that it almost overflows!
"One stalk of rice yields more than 700 grains, and the piece of land plowed by porpoise is worth 1,000 grains per stalk! This is simply"
The old patriarch clicked his tongue!
Yan Zai once said to Huang Kanshan that the combined use of land, water, and planting methods may produce a thousand grains per mu, but now, this scene is also covered by tillers, essences, and reeds. The soldiers saw it.
Baihuangqi and Huangliyin huddled together, holding a big and fat rice stalk, which they specially kept after picking it from the field, and they were about to send someone back to the three mountains and four fields at this time .
"Tell Wu, the Chifang family really had a bumper harvest this year. There are 1,300 grains on this stalk of rice! Back in our days, it was a blessing to have 2-300 grains on a stalk of rice!"
This is almost more than quintupled!
And Lugao also took a stalk of grain and asked the soldiers of the Lu family to bring it back to the wilderness of Zaoli, because the Lu family mainly focused on fishing and hunting, with farming as an auxiliary, but the old wizard said that if a few years later, he said It may not be necessary to give up fishing and hunting and switch to farming, mainly because of the flow of water veins in the field of Zaoli.
But now, following the Chifang family, even if they switch from fishing and hunting to farming, they will not fall into the situation of lack of experience and lack of harvest, or lack of food, which will lead to complaints from the tribe.
In a word, stick to the line and follow Chifang, there will be food and a good harvest.
"The red side divides the land, the yield per mu is more than three stones, the good land is more than five stones, and the annual harvest is almost incalculable!"
When the soldiers from the three mountains and four fields took these bamboo slips back and sent them back, they had mixed feelings.
Mu and stone in the past dynasties are different. The most famous one is that one stone in Tang Dynasty is equivalent to three stones in Han Dynasty, and one and a half stones of millet in the early Warring States period is equivalent to nine buckets in later generations. In the Qin State¡¯s land beside the Zhengguo Canal, one mu of land can harvest grain for one bell, and one bell is six stones and four buckets, which is equivalent to three stones, eight buckets and four liters per mu. This is why it is said that Zhengguo Canal, Dujiangyan, and the land of fat Bashu , the reason for casting the land of abundance.
Because the Chifang family is close to Daze, the water in Yanzhize is not as deep and vast as Dongting Lake. big project.
However, some basic water conservancy facilities, such as waterwheels, have been built and joined the irrigation ranks early. Although they are primitive and not durable, don¡¯t worry, because Akakata now has a senior carpenter from Nakahara. division.
The biggest project is the earth dam that Dayi participated in the construction of.
However, due to the emergence of various farm tools, composting, retting and other methods, coupled with the effective avoidance of insect damage, and the blessing of the harvest beast, the Akakata family still achieved an incredible yield per mu in the mountains and seas.
The yield per mu is three stones, seven buckets and nine liters. This is the calculation of later generations. It has fully reached the level of the Qin State in Bashu in the Warring States Period, and the level of Qin State, even in the Western Han and Eastern Han Dynasties, is definitely among the best.
Next year, when the real, big canal is built, this output will continue to increase!
?The production of irrigated fields close to water flow is much higher than that of unirrigated fields, generally about two to five times.
For Yu Zai, the yield per mu is two to three hundred catties, which was only seen in the prosperous ancient times. This year is a surprise. For more than three thousand catties, there is still a big gap
However, large tracts of land in the south have not been developed, and the abundance of land is unimaginable! Now is just the beginning! Here, after all, is a world with divine power and spells! Productivity is not enough, divine power will make up for it!
And the land cultivated by Dolphin has an yield of more than five shi per mu!
There are thousands of rice in the ground!
And they believe that their own tribe, which has learned the composting method before, will definitely be much better than in previous years, even if they do not have as much harvest as the Chikata Clan!
"With food in hand, don't panic!"
