Chapter 273 Pedal Thresher
Chao Chao was busy asking in her mind, "Is it because of yesterday's fire? How much has it increased?"
"Three thousand eight."
Chao Chao was surprised, "So many?"
Ah Shan explained to her, "Because you saved more than three of you yesterday, if no one noticed at the time, the fire would have spread quickly. There were many families living upstairs at the time, and it was after school, so most of the people at home were children and elderly people with mobility problems. There was also a patient lying in bed next door to Feifei's house, and it was the property management who carried him down in time, otherwise he would have been in trouble. You called Uncle Zhou, and Uncle Zhou contacted the property management and the fire department in time, so there were no casualties."
Especially when the fire truck comes, if it is a little later at night, it will be blocked on the road by the car accident ahead. Even if it is blocked for two minutes, the consequences will be disastrous.
In fact, according to Ashan's calculation, three thousand eight is still too little.
Not to mention others, just Chao Chao herself, her worth should be several thousand.
After the system calculated, it actually gave one thousand because Chaochao was using it to help.
It makes me angry just thinking about it.
But for Chao Chao, he is already very satisfied, and what’s more, he feels the sense of accomplishment of saving so many people.
Seeing that she was happy, Ashan didn't say much.
Feifei, however, was a little surprised to see Chaochao remained silent, "Chaochao, why aren't you talking?"
"Ah? Well, I, I was thinking." Chao Chao quickly came back to his senses.
Jian Yunsang in the front seat couldn't help laughing when he heard this, thinking? Maybe he was talking to Ah Shan?
"Thinking about what?"
Chao Chao, "Think about whether to take a nap first. Mom said that the place we are going is a bit far. Feifei, are you sleepy?"
Feifei was actually very sleepy. So many things happened yesterday that she felt uneasy sleeping in the hotel with her mother at night. When she woke up in the middle of the night, she found her mother standing by the window crying, and she couldn't sleep even more.
So when she heard Chaochao say this, she nodded.
She slept very deeply, and when Feifei woke up, Jian Yunsang was backing into a ground parking space.
Feifei turned her head and saw Chaochao lying on the window looking out.
She rubbed her eyes and asked, "Where is this?"
"It's a farm tool museum. Mom brought us here to visit today."
As they were talking, the car had already stopped. Jian Yunsang got out and said to the two children, "Let's go in and take a look."
She asked the two, "Are you hungry? How about eating something and drinking some water first? It will be inconvenient to eat when we get inside."
Chaochao was not hungry. Feifei didn’t eat much in the morning. She took the bread and ate half of it. Then they walked inside.
The people of the Daqi Dynasty were cheered up and stared at the sky without blinking.
Here it comes! The farm tools of later generations can finally see the true face of Mount Lu.
In fact, they have seen farm tools in the countryside. Isn't Jinwen Village a small village? It's just that most of the people in Jinwen Village grow oranges. What they have seen most is the scene of harvesting oranges. The farm tools are baskets, shoulder poles, scissors, snakeskin bags, and carts. These are not surprising. Except that the snakeskin bags are different from the sacks of Daqi, everything else is available.
However, things are different now. Now Miss Jane is introducing these things specifically and purposefully.
The farmers are too busy working at the moment, as most of them dare not miss even a single moment of the scene.
Although they knew that even if they were introduced to farm tools, they didn't have the skills and might not be able to make them. But it didn't matter, the whole Daqi was watching, and the emperor would ask the officials in charge to make the farm tools, and they would naturally use them when the time came, so they would always know how to use them and what their specific functions were.
Not only them, but there were also many craftsmen, most of whom held charcoal pencils, and some even bought a few sheets of paper, intending to draw while watching, and then try to see if they could make it.
If they were like this, the people in the Ministry of Works were even more on high alert.
Jian Yunsang walked into the house holding the hands of the two little girls, one on each side.
This kind of museum is located in a remote place, so there are not many people on weekdays. But today is the weekend, so it is a little more lively.
Jian Yunsang specially hired a commentator to start the story from the moment he entered the door.
The first thing you see when you come in is a thresher.
Jian Yunsang didn't know much about this, and although he had done some homework, the commentator was obviously much more professional.
The young girl spoke in a clear voice and was particularly patient with the two girls. "This is a thresher, which is mainly used to thresh grains. The one in front of us is a pedal-operated thresher, which was developed in 1972."
Jian Yunsang knew what the people of Daqi wanted to hear, and would ask some appropriate questions during the explanation.
"What is the difference between a pedal thresher and an ancient thresher?"
The narrator smiled and said, "Okay, then let me tell you about the advantages and disadvantages of the ancient threshing machine and this threshing machine. In the earliest primitive manual threshing stage, threshing sticks and stone scoops were used. The ears of grain were beaten with wooden sticks or pounded with stone mortars. As a result, the efficiency was low and the grains were easily damaged. In ancient times, the per-acre yield was already low, and part of it was lost during threshing, which made the farmers' food even more scarce."
"Later, during the Ming and Qing dynasties, an open-topped wooden barrel appeared, called a thresher, which lifted the rice ears high and threw them onto the slanted wooden bars in the barrel. However, this method required strong labor to operate, and the daily threshing yield was less than half an acre, and the loss rate was as high as 15%."
When some of the people of Daqi heard this, they couldn't help but look at each other in confusion.
Yes, yes, yes, they have already used this kind of thresher in some places. Although it is better than the previous threshing stick, it is not very efficient and very tiring.
They don't eat much and consume a lot of physical energy, which is actually very uneconomical.
But there's nothing we can do about it, this is already an improvement.
So, is this pedal-operated thresher in front of you a big change?
Soon, the narrator continued to introduce, "At the end of the 19th century, a bamboo threshing machine appeared. It was made of bamboo boards and wooden poles. People could stand and turn the bamboo poles to beat the rice stalks, which reduced fatigue. Unfortunately, the efficiency improvement was limited."
"It was not until the 1950s that iron rollers appeared, with blunt nails embedded in the surface and driven by hand-cranked gears. This type of thresher did improve the threshing efficiency to one acre per day, but it consumed a lot of physical energy and was not cost-effective."
The people of Daqi, "..."
Are you not satisfied with processing one acre? It's better than processing less than half an acre a day, right?
The narrator said, "In some places, water wheels or ox power are used to drive the rollers. However, this method requires terrain, is restricted by height, is inconvenient, and ultimately cannot be popularized."
At this point, the narrator immediately pointed to the threshing machine in front of him, "Then, there is this pedal-operated threshing machine in front of us."
