I went ashore by weaving straw shoes and became a master craftsman

Chapter 308 Improved Rockets

Mrs. Zou saw that Wang Gefei's words were insincere, so she changed the subject and asked, "Didn't you say that there will be a county competition on the first day of September? Why don't you prepare for it?"

"This county exam is related to basic skills. I haven't stopped practicing basic skills since I became a prospective craftsman. I have been preparing for the battle for a long time. Don't worry, sister." Wang Ge gave a rare mischievous smile, and said again: "Just now in Gongcao, I saw Gongcao Shi is in a hurry to build a large number of rockets. She is recovering from her injuries. How can she worry about these things every day. And it is also my request to improve the rockets before the county exam. It is a challenge. Sister, these words cannot be compared with Gongcao Shi said that she has taken care of me enough."

"You. That's you, you're going to expose me in front of my face!"

"What's the bottom?" Hearing the sound before meeting people, Miss Nan entered the courtyard with a happy smile as usual.

After a few words of joy and laughter, Mrs. Zou entered the room and stopped disturbing Wang Ge.

Wang Ge first drew the structure diagram of the current rocket on the ground, and while drawing, his mind was a little distracted. Of course, he was thinking about the county competition that Zong Jiangshi proposed.The topic is to make wooden gears according to the mold, which is divided into two sessions.The standard of the first test and the quantity of the second test.

Specifically, it is the first test to assess the craftsman's mastery of the rules. Gong Cao Shi also revealed that the size requirements this time will be as fine as one-half of the "dividing distance".

Those who pass the first round can participate in the second round or give up.The competition time is exactly twelve o'clock, and the wooden gears that were chiseled in the first round are still made. Whoever makes the most standard parts will win the first place.Note that those who are not in the top ten will all be punished.

When Mrs. Duan told Wang Ge, she bluntly said: "The harsh punishment is to prevent wood waste. The standard wooden gears made by candidates are all used to make mileage cars."

When building roads in Jiashe Village, Wang Ge had seen the simplest single-story mile car. Every mile, the wooden man on the car beat a small wooden drum.After a long time, she learned from Huan Zhen that the car in Jili had double-deckers, and each trip was ten miles. Through the meshing transmission of the gears, the wooden man struck the copper bell automatically.

In the Jin Dynasty, there were only three situations in which Jili chariots were used: first, when the emperor was on tour, it was used as a ceremonial chariot, and the number of horses pulling the chariot was fixed at four, and only the guide chariot was in front of the Jiri chariot; second, it was used for road construction. Before, the measured road length was combined with the road width to calculate the amount of mellow soil consumed, the amount of cultivation tools to be prepared, and the distribution of labor. Vehicles, accurate measurement can ensure subsequent planning, such as building defense pavilions and wild pavilions, map revisions, etc.

If the territory after the war can be measured with a mileage cart in the future, the mileage will be based on the wards piled up by the soldiers along the road. Normally, there are five mile piles per mile.

No more gossip.Wang Ge focused his mind and began to think about how to improve the oil sac.The original structure is to tie the oil bag between the "﹀"-shaped wood chips, and use the pullback of the machine to drive the wood chips behind the "﹀" to squeeze the oil bag flat.

Without considering changing the extension pipe for the time being, just increase the number of oil pockets...Wang Ge first draws a rotating wheel composed of several "﹀" shaped wood pieces according to the idea.Improving any equipment has to be done step by step, there is no rush.She drew six "﹀" shapes, and it is feasible to tie oil pockets in each depression.

Then add the six oil bladder diagrams to the mockup.

The second step is to realize the rotation function of the rotating wheel.This will change the overall connection of the handle of the lower part, the mechanism and the upper part.She removed the "shaft" that had always been on the top of the model, and thought it was not obvious, so she moved her knees to a place, lay down close to the ground and re-drawn the exploded view of "the second step", separating the upper half of the structure from the lower half of the structure by three inches distance.

The leaves and dust began to blow all over the courtyard, and the cool wind started, is the weather going to change?
Mrs. Zou called her: "Go inside and paint, otherwise it will be useless when it rains later."

Wang Ge said with a smile, "Then I'll spend a little extravagant time and write."

The county office has long provided her with a desk. Pens, ink, bamboo slips, and bamboo are all consumables. She is allowed to receive these four items on a monthly basis.

The two candles were all lit, and soon Wang Ge was immersed in thinking again.Mrs. Zou sewed clothes, and Mrs. Nan sewed cold shoes. Although the door of the house scraped from time to time, the three of them were busy with their own business, and gradually became quiet, as if they were cut off from the outside world.

The wooden wheel supported by the six oil bladders is not difficult to rotate, but the difficulty is how to connect with the extension tube every time the mouth of the bladder is rotated up?
There are two options.One is to change the extension tube into a funnel shape, with the big mouth at the back, just covering the rotating wheel. In this way, no matter how the wooden wheel rotates, whichever oil bag is the turn to spray oil, it will pass through the extension tube and then the tinder; It is disconnected from the oil nozzle and not directly connected. Instead, a "︺"-shaped curved handle is added to the bottom of the extension pipe. The inclined wooden handle behind the "︺" is inserted into the main part in the form of tenons, and the specific position is in front of the machine.

At present, it is impossible to say which plan should be improved. Wang Ge has always been troublesome in doing things, so he will first consider the first one with all his thoughts.As soon as she started to write, the problem came, no, don't waste ink and wood, she held the candle lamp in her left hand and the chisel in her right hand, and when she reached the corner, she was still drawing on the ground.

Mrs. Zou and Mrs. Nan looked at Wang Ge, but they didn't care.

The new problem is that the extension tube and the tinder are integrated, so it is not necessary to consider that the tinder rotates with the rotation of the extension tube. What matters is that the tinder is useless after a flame is sprayed once.You can't have six oil sacs with six pieces of velvet, can you?Moreover, the tinder has to be covered with a wooden tube, and the cover must be removed before use. Is it possible to spray the flame six times and pull it out six times?
No, this ignition method is too stupid and consumes too much tinder.

Could it be replaced by fire bars?should be able to.

Wang Ge erased the tinder pattern on the ground and replaced it with a "bar" pattern.The advantage of using the fire-inch strip as the igniter is that you don't need to care about how it is placed, and it doesn't matter if it turns horizontally or vertically with the extension tube.

So the next thing to consider is to manually install a new fire strip at the original ignition position after each flame is sprayed?Or install new components and use robotic arms instead of manual installation?
Manually change the fire bar...you have to add gloves for each soldier, because the extension pipe is changed to copper as a whole, and the temperature is extremely high after spraying fire.But even with extra glove supplies, it's still cheaper than the second idea.

She is just a carpenter, and it is up to the officials to decide which improvement method to choose. She drew the structure of the mechanical arm, which is very simple, and can use wood, two sections of rods, and one shaft.

The backswing is equivalent to an extra "handle" on the rocket, which is located in front of the machine (the machine is in front of the real handle).The end of the upper rod is connected with the upper end of the lower rod with a shaft.The end of the lower rod is equipped with a fire clip, so the upper rod must be short and the lower rod must be long to realize the function of lifting the lower rod and instantly igniting the fire strip on the extension tube.

The operation method is: every time when the fire is sprayed, the mechanical arm is raised, and the mechanical arm is lowered before the fire is sprayed, so that the maximum distance of the fire fold is lowered, and it will not be affected by the flame range.

So far, the most critical improvement of the first plan has been completed.

Wang Ge looked at them repeatedly, simulating their real shape in his mind, and after a little adjustment, he began to mark the size of each component.

The process of marking the size is also a process of adjustment.

When the rumbling thunder sounded outside, she turned her head and saw only Mrs. Nan was there, so she couldn't help asking: "Sister, what time is it?"

Lady Nan put down her needle and thread, and smiled gently: "You Chu, your sister Zou has gone to the kitchen to get dinner, and she will be back soon."

　椠 (qiàn): A wooden board without writing is called a 椠, and a wooden board with writing is called a tablet.

　　In the future, wherever I mark "involving production", it means that there are many wood-making processes in this chapter.As an author of this type of novel, I can't pass the plot in a few words.
