Yang Yuanzhao is an engine engineer, he is quite familiar with the structure of tractors, and it is very difficult to apply the small BMW 999 engine to the tractor, even if he is experienced.

After thinking for a long time, Yang Yuanzhao slowly smoothed out his thoughts, added some things that can only be used in high-end cars, and completed the mechanical transmission, power tools, and the most important thing is the engine and transmission.

Later generations Yang Yuanzhao has seen more tractors, relatively speaking, small, not very suitable for a large farm like Baotou, Baotou thousands of miles of fertile field, although 220 hectares of land, not connected together, but only divided into two large and small pieces, belonging to two large landlords, they are obvious, in the choice of land, specially integrated, so the land of the reclamation company is two large pieces of land, each of which exceeds 10,000 acres, can be said to be a veritable farm.

Since it is a big farm, it can only be a large, large tractor, BMW 999 193 horsepower, barely can, tires are a big problem, huge tires, definitely a roadblock.

In this era, there has been vulcanized rubber technology, but this technology in a certain way, belongs to high-tech, the United States in the early 20th century, has owned a large number of cars, the famous Ford is relying on the T-type, the epoch-making cheapest model, has become one of the leaders of the American automobile industry, the Ford family also began his rise process, but even Ford cars, did not use tires in the real sense, he used gun wheels, that is, wooden, Most of the cars born in this era were either made of wood, or tires wrapped in a layer of rubber or other things, and inflated tires, which were still a utopian dream, and would not be used until almost 20 years later.

The all-in-one machine is very powerful, but it can't make things out of thin air, rubber, in Yang Yuanzhao's view, may also be a kind of organic matter, whether it can be copied, it is really difficult to say, then he has only one choice.

Crawler, crawler tractor, a certain amount of dù above, is the basis of the tank, until one or two decades later, or even World War II, will get a huge development, to World War II, will get a rapid development, the general crawler is among the large machinery, such as large excavators, bulldozers and the like.

Crawler type, Yang Yuanzhao has been contacted, the early crawler type is very simple, regardless of speed, just considering the efficiency and function of entering the farmland, the crawler type is still acceptable, and the huge force area will make the bulldozer reduce the pressure of the land to the minimum, which is conducive to the further improvement of his function.

It seems that before walking into the tip of the horns, the crawler type can be solved, the crawler type is nothing more than the use of transmission devices, running the track wrapped outside, under the premise that large tires and special tires are not solved, the crawler type is a necessary device for the tank, the pressure of dozens of tons of tanks, divided into the huge track, the oppressive force of the land and the road is small, and the most important thing is that he can pass through most of the environment on the battlefield, especially the battlefield environment full of craters and obstacles, for example, Trenches that do not exceed the overall length of the car, some slightly steeper slopes, and some steps that are not too high can be passed.

In this era, the use of crawler type is not slightly earlier, Yang Yuanzhao carefully thought about the following, crawler, I am afraid that the only key to solve the problem of tractors, recall, after calculating a few problems, he found that he did not have much contact with the crawler, but he could barely make zuò out, perhaps in terms of speed and flexibility, and the crawler type of later generations is far away, but it is also much higher than this era.

Since the problem of the chassis is solved with the crawler type, then the problem of tires is not considered, and the rest is to integrate all the collectives, use some fixed structures, and imagine the various components of the tractor, carefully check it, and there is no omission, Yang Yuanzhao asked: "Ding Dong, how do I generate drawings, or do I imagine it directly?" ”

"Yes!" Tinker Bell replied in the affirmative.

Yang Yuanzhao began to sketch the drawings of the tractor in his mind, which looked a little strange, but it could achieve all the functions of the tractor, it took more than 10 minutes, and finally completed all the sketching process, he thought that he could successfully complete the copy of the drawings, but when the drawings were generated, a purple light suddenly turned in front of them, and the drawings turned into ashes out of thin air.

"W-what the hell is this?"

"Verification failed!" Ding Dong said calmly.

"If you fail, why did you fail?" Yang Yuanzhao said slightly distractedly.

"Of course, according to the drawings you envisioned, you can't even complete 30% of the tractor, how can you get through guò?" Ding Dong's words were calm and unceremoniously, which made Yang Yuanzhao embarrassed for a while, yes, he was not familiar with tractors, but according to mechanical principles, he reluctantly completed the imagination of different components of the tractor, integrated together, strange appearance, and if successful, it may not be able to last long, not to mention, the overall 30% can not be completed.

Yang Yuanzhao looked at the empty space, and asked in his heart: "Ding Dong, how can I improve the degree of completion!" ”

"This, according to the rules, I can't instruct you!"

Ding Dong's words made Yang Yuanzhao slightly disappointed, but when he raised his eyes, he saw the smile on the corner of Ding Dong's mouth, and suddenly realized: "What am I going to do now!" ”

"Don't you have a book about engines, go try it!" Ding Dong said casually, but Yang Yuanzhao understood for a while, Ding Dong may be because of some kind of rule, he can't directly guide him, and he can't do anything about how to improve, but in the case of another question, the answer can be found.

When I crossed over, I was wrapped in an all-in-one machine and brought a lot of things, including a small bookshelf next to the workbench, on which some reference books were placed, most of which were whole engines.

Out of the drawing area, Yang Yuanzhao rummaged on the small bookshelf for a while, and soon found this book, the history of the engine car, the detailed description, starting from Watt's improved steam engine, the history of engine development, among them, there are some drawings, although it is only simple, the simplest drawings, but it gave Yang Yuanzhao a lot of inspiration, especially later, based on the engine after the founding of the People's Republic of China, which discusses in detail the specific development history of the engine, and the things about the engine, are all brushed aside.

Obviously, if you want to determine the success rate, this book is a breakthrough, take this book, and quickly turn to the principle of the Watt steam engine, Yang Yuanzhao began to enter the drawing area after some imagination, and began to verify the new drawings.

Watt's improved steam engine is outdated compared to this era, and Yang Yuanzhao's era is even older, Yang Yuanzhao according to some descriptions in the book, plus his own imagination, the moment the drawings are formed, the light flickers again, and it fails again.

This failure, did not discourage Yang Yuanzhao, but peaceful, continued to verify the other drawings, the whole book, more than 30 different engines, a total of guò verification, the formation of drawings is 5 models, others, without exception failed.

Yang Yuanzhao was delighted in his heart, he finally found the reason, whether the engine is advanced or not, just like Watt's steam engine, the first diesel engine and internal combustion engine are the same, in this era, in foreign countries have been made, it can be said that the technology content has been very low, but Yang Yuanzhao still has not done it, the reason is that he is not familiar, but the old liberation 88 horsepower engine, Santana engine, two-stroke and four-stroke motorcycle engine, but successfully completed the drawings.

In terms of the level of the engine, whether it is the old Jiefang 88 horsepower engine, or the Santana, or even the engine of the two-stroke and four-stroke motorcycles, his performance indicators are much stronger than the engines of this era, but they succeeded, the reason is that whether it is in school or after graduation, Yang Yuanzhao is almost often in contact with these engines, and even familiar with each of their components, With the help of this book, after the memories were clear, this was successfully verified, as for the others, even the simplest Watt engine, he could not generate drawings out of thin air.

Yang Yuanzhao smiled bitterly for a while, the reason for the failure of the tractor was found before, with the engine of BMW 999, but this is the engine of a motorcycle after all, the structure of the tractor is simple, but the engine of BMW 999 is applied to the tractor, there are many things that need to be changed, a lot of things, he almost didn't think about it, so it is normal to fail.

It seems that directly on the train, the idea of designing a tractor is basically in vain, after all, he does not have a qualified tractor diesel engine, can not borrow the previous mechanical structure, the changes he made, maybe can, may not be, must rely on step by step of the real yàn, this can complete the setting, which is also the root cause of the failure of his drawings.

It's a pity, although there is no way to use the BMW 999 engine, complete the transformation and setting of the tractor, but unexpectedly get the drawings of 5 engines, although only manufacturing drawings, no material drawings, so produced engines, in many aspects, and the original will have some gaps, but with the BMW 999 engine this treasure trove, after the use of things figured out, it is not impossible to solve.

found the reason, Yang Yuanzhao also calmed down, for the time being, the tractor can only be studied, fortunately, the engine and chassis are almost the same, but the various components of the tractor, the combine harvester and the part of the machine farming, are not particularly familiar, the picture seen by later generations must continue to scrutinize, this can be completed.

It seems that to return to Baotou, in order to be able to carry out the next real yàn, only in the actual operation, slowly change, can make this tractor form, not to complete the entire drawing at one time, but also to obtain a lot of results, a certain Cheng dù above, he smoothed out the idea.

In the next journey, Yang Yuanzhao has been perfecting this thing, and the hope of one-time molding is basically gone, but improving the system in all aspects can be done, and just as it was about to start, the voice of Jingle suddenly sounded: "Someone is in contact with the master's body in the outside world, please go out immediately!" ”
