chance world

That night, Ding Qiyu sat at the table and considered the issue of farm tools. Recalling the basic knowledge of farming that he had learned before, the most tiring step before sowing should be plowing.According to what Ding Qiyu knew, most of the people in her family and even in Hejia Village plowed the land with hoes.At most, there are a few companies with better conditions that can buy an old ox and a simple iron plow that is pulled by an ox.

Ding Qiyu originally wanted to buy a cow, but Aunt He felt that there was no need for such a little land at home, so she didn't buy it.Therefore, what Ding Qiyu mainly wanted to design was an efficient and labor-saving manual plowing tool.Resting his chin on his right hand, he fell into deep thought. The first image that appeared in Ding Qiyu's mind was the plowshares of various advanced cultivators in "Farming Simulator".Since it is the most advanced farm tool, there is a reason why it is so advanced. At that time, it was only for playing games and I didn’t think about it. Now I recall that the shape of the plowshares in my memory is basically the shape of a leaf with two ends cut off, but this leaf was The configuration of the space surface is distorted.In addition to the plowshare, Ding Qiyu also combined the vague impression of the "curved plow" in the history textbook of the year and the vertical and horizontal configuration of the plow frame on the plowshare in "Simulator Farm", and outlined a complete structure in his head.

Ding Qiyu found a piece of wood as a paperweight, instead of holding down the paper with his left hand, he picked up a bamboo tube pen and drew a schematic structure diagram on the paper. The key points to be analyzed were the shape of the curved surface of the plowshare, the force of the plow frame and the relationship between man and machine.It is not convenient for me to make an experiment with the shape of a one-armed hero. I can only rely on drawings and assumptions for theoretical analysis of movement and force.The angle of distortion of the space surface, the depth angle of the plowshare into the soil, etc. are all parameters that need to be assumed and checked. Ding Qiyu’s calculations are a bit broken, and the manuscript paper is filled with paper after paper. The same set of methods brings in different parameters. The value has to be completely recalculated by hand. How much she wishes at this moment to have a computer that allows her to program a program, enter the parameters and get the result directly... After a whole night of calculations, Lian Er came to ask her why she was not asleep. , she has completely determined the relationship curve between the two parameters and the user's force.At this speed, it will take two or three days to finally fully determine the main structural data of this thing.After confirming the data, we can make a real object for testing when the arm recovers a little.At this time, it has just entered August, and there is still plenty of time before late autumn in September.

I have to say that the medicine the doctor used (and the pig's trotters every day) had a very significant effect. About ten days later, Ding Qiyu's arm was much better. Together, the surface of the wound has begun to scab, and the left hand can already exert some strength.Every time it was time to change the dressing, instead of Ding Qiyu going to the doctor himself, Qing'er would take the doctor there to find her. This made Ding Qiyu very happy, because it showed that Miss Lu had always cared about her injury.Ding Qiyu guessed correctly, Lu Weixi had indeed been paying attention to Ding Qiyu's injury all the time, and even wanted to ask him face to face, but Ding Qiyu just listened to the piano in a regular manner every day, and neither of them broke the persistence and tacit understanding of this bosom friend .This made Lu Weixi feel that it was not good for him to take the initiative to care about Ding Qiyu.

Ding Qiyu had already obtained the best theoretical data for the plow tool, and also checked the strength of the material, because the plow share below is in the shape of a space-distorted blade, so she decided to name this new type of plow tool "Curved leaf plow".

Can't wait to put the curved leaf plow that I had calculated and designed before into practice. Da Niang and Lian Er strictly forbid Ding Qiyu from engaging in all activities that require the left hand to use strength. Ding Qiyu can only secretly take away his drawings and tools and hide them These materials were on the carriage and brought to the small courtyard of the General's Mansion.After listening to the piano at noon, I started making curved leaf plows.Of course, Ding Qiyu didn't dare to be too presumptuous. Wherever he could use his right hand to exert force, he used his right hand, and his left hand did some simple auxiliary work.Although after a few days, my right hand is almost useless and sore, but looking at the formed Qu Yeli, the sense of accomplishment is indescribable.

When she took Qu Yeli home and showed it to Aunt He and Lian Er, they realized that this guy had been hiding in secret for so long. Unfortunately, Ding Qiyu had already killed him and played later. Fortunately, the injury did not worsen, and it was fine after being severely criticized and educated.At this time, the family's field had finished harvesting, and Ding Qiyu took Lian'er to the field to test her curved leaf plow.According to the experience of the actual operation and Lian Er's suggestion, Ding Qiyu got suggestions for improvement and inspired a lot of new inspirations at the same time.

Ding Qiyu fine-tuned the parameters of the first version of the curved leaf plow according to the actual situation; adding a rotating shaft, limit device, buckle, etc. to the joint of the plowshare to form a two-way conversion mechanism, so that the curved leaf plow can be used in both directions. Moreover, it can be pulled or pushed, which greatly improves the convenience; finally, according to the difference in soil quality, the most suitable inclination angle of the plowshare under several soil types is obtained through testing, and the inclination angle is also added with an adjustment mechanism to make it It becomes a parameter that can be adjusted manually, so that users can adjust to the most suitable and labor-saving angle according to different soil conditions.

After a series of tests and improvements, Ding Qiyu's curved leaf plow was finally born.Among them, Lian'er also contributed a lot of mental and physical strength, allowing Ding Qiyu to see that Lian'er actually had great wisdom hidden in her little brain.To celebrate the birth of Qu Yeli, Lian Er made a table of delicious food as a "celebration banquet".Except for the sudden appearance of pig's trotters that made Ding Qiyu a little nauseous, she still ate very happily.

The next day, Ding Qiyu returned home early from the city, and the family took Qu Yeli to plow the land in their own field.Some villagers have seen the scene of Ding Qiyu and Lian Er testing Qu Yeli together, and they thought it was quite novel before, but today they saw that it was officially put into use, and they all came to watch.Originally, it took a lot of effort to plow the land with one hoe and one hoe. Ding Qiyu just pushed the curved leaf plow with his right hand and controlled the direction with his left hand. The places he walked were all plowed. .Moreover, the loose soil is thorough and even, which is much better than the effect of plowing with a hoe.

"This is so strange!" "I've never seen such a thing before." "Yeah, I saw the ox pull the plow to plow quickly, so I just thought about it, and I also dragged the hoe to plow the ground. It can’t be dragged. Why doesn’t he push it hard at all?” “It’s still neat after plowing, and it can be directly sown!” There are more and more people onlookers, and there are endless discussions. Ding Qiyu was curious and envious of what he was holding.

"Hey, Ah Yu! Can I try it?" The young man who knew Ding Qiyu on weekdays shouted at her, and everyone onlookers were eager to try.

"Hehe, that's fine, come on, you're like this..." Why not do it when someone helps your family cultivate the land?And seeing everyone's interest, Ding Qiyu felt that this was a good opportunity to promote Qu Yeli.The things I make are not only to improve the lives of my family, but also to be used by tens of millions of people in Qianguo, and only in this way can I get closer and closer to my goal of becoming a master of mechanics.

The first young man who came up to try it went back and forth according to the method Ding Qiyu said, and exclaimed in surprise: "Ayu! You are really amazing, and you are really not tired at all!"

Before Ding Qiyu could answer the previous one, several young people enthusiastically signed up: "Ah Yu! Let me try too!" "Ah Yu, I want to try too!"

"Haha, you can try whatever you want, don't worry, don't worry." With free labor and an advertisement, Ding Qiyu laughed so hard that Lian Er next to her couldn't help poking her embarrassing head.

In just one hour in the evening, a large area of ​​Ding Qiyu's land was plowed by everyone trying to try it out.Excluding the teaching time, Ding Qiyu made a rough comparison. Compared with the hoe, the curved leaf plow can shorten the plowing time by 6 or 7 times, and the effect is very significant.

Qu Yeli became popular in Hejia Village that night, and many people wondered if they could borrow Qu Yeli from Ding Qiyu.With so many families, it is impossible to borrow.Ding Qiyu saw a business opportunity from it. The cost of his curved leaf plow is not high, and it is also very fast to make.The main efforts and painstaking efforts are spent on the preliminary design and parameter calculation. Once the structure is determined, it will be produced very quickly, so it can be sold at a very reasonable price.His organization has been affirmed by so many people, this night, Ding Qiyu quickly fell into a dream with longing for the future.

The next day, Ding Qiyu went to work in the city as usual.In the afternoon, one of the shops that had been planned to be inspected happened to be closed, and the next shop was far away, so Ding Qiyu decided to end the day here and go home early.Thinking about Qu Yeli's production and sales plan in his heart, when he was about to get home, he saw the courtyard door was open from a distance. Everyone knew that this carriage belonged to the General's Mansion, and no one dared to do anything to it.Just in case, Ding Qiyu pinned the flying arrow crossbow to his waist before walking towards the door of the house.

Before I entered the courtyard, I heard Aunt He scolding at the top of her throat: "You damn girl is learning more and more wildly from that stinky beggar, and you dare to yell at my old lady! Today I will do it for you I will teach you a lesson!"

Hearing the sound, Ding Qiyu was furious, and as soon as he ran into the room, he saw Aunt He with a ferocious face, holding Lian Er's arm with one hand, and raising her hand high, about to slam Lian Er's face fiercely.Aunt He's stout and solid body was in stark contrast to Lian'er, Lian'er, who was held tightly by her arm, couldn't break free at all, and the slap was unavoidable.

"Stop!!!" Ding Qiyu yelled angrily and rushed forward, but he didn't have time to stop Aunt He's movements, and then there was a crisp "pa", Lian'er's petite body was slapped vigorously The fan lost its center of gravity in an instant, and fell out like a fluttering catkin.Ding Qiyu felt his brain explode with a bang, he rushed up to catch Lian'er's body that was about to fall, and held him tightly in his arms.
