When Zhao Wenshan went back to the county to purchase materials, he went home by the way, and recently he has been going out early and returning late, so it is necessary to explain to his father, so as not to worry about others. Pen, fun, and www.biquge.info

found his father, before Zhao Wenshan could speak, his father asked with concern: "Shan'er, what have you been busy with these days?" There was no one to be seen all day long. ”

"Dad, the child met a new friend a few days ago, do you know who it is?"

"It can't be Wang Haoran, right?"

"Dad, how could you guess?" Zhao Wenshan was surprised.

"A few days ago, my father received an application from Wang Haoran to build a cast iron kiln, you know, the imperial court has just completely banned private cast iron this year, but this kid can get His Majesty's royal approval so quickly, and his ability should not be underestimated! Shan'er will associate with him in the future, and remember not to offend him. "That's right, Zhao Wenshan's father is Zhao Yuankai, the assassin of Puzhou!

"Don't worry, Dad, the child can be saved. The child and Wang Gongzi are making harvesters these days, and sometimes they don't come back at night, so please don't worry about it. ”

"Well, why don't you call a few slaves to follow you, if there's anything, someone can call on you."

"No, Dad, the kid still has to buy some materials for the harvester, so let's go first."

"Go, if you are short of money, go to the account office and get it."

Zhao Yuankai is a well-known corrupt official in Puzhou, who loots and oppresses his subordinates and flatters his superiors. He himself knows that he is not a good person, but he is selfless to his family. Many years ago, he was demoted for impeachment, and was tragically looted by robbers on the way to office, and his wife, in order to avoid being humiliated by the robbers, used a trick to grab a knife to confront the robbers and said: "If you want to kill me, let me add a knife and saw, if you want to die, you can come and force you." In a fit of rage, the robber shot her with an arrow. After Zhao Yuankai, who survived with his anger, escaped, he finally caught the robber who shot his wife and dismembered the robber in front of his wife's grave.

Zhao Yuankai never remarried, and depended on his only son. He didn't want his son to be as notorious as he was, so he named him Good. As he expected, Zhao Wenshan was sympathetic to the people, especially concerned about the cultivation of farmers, and also made great achievements, such as the invention of wheat samarium, and the traditional straight plow changed to a curved plow......

Wang Haoran got the permission to build the factory and the land purchased by Xie Changfu in a few days, and when Chen Jie came back from Chang'an with his people, Wang Haoran asked Luo Ping of the construction team to be responsible for the construction of the Puzhou plant. Before Luo Ping came to Puzhou, he was in charge of planning the buildings that the client needed to build in the original construction team, and Wang Haoran recognized his ability, so he was relieved to hand over all the construction of the Puzhou plant.

When the day came when the rice could be harvested, Wang Haoran and the others couldn't wait to drive the harvester to the field. At this time, there are also some farmers who are harvesting rice, and they have put down their work and run over to see the excitement when they see this strange thing.

"Zhao Gongzi, what kind of good things have you made again?" Some villagers asked Zhao Wenshan that although the people were very dissatisfied with Zhao Yuankai, they respected his son very much, because Zhao Wenshan had made many tools for farming before, which increased the work efficiency of the people by more than ten times.

"Haha...... This time I didn't do this thing alone, these friends are the main force, I'm just a helper. Zhao Wenshan did not take credit, and introduced Wang Haoran and them to the people one by one, but Wang Haoran told Zhao Wenshan before that he didn't want to show people by his real name, so he was called a son when he introduced.

"This thing is called a harvester, it can harvest rice, it can also harvest wheat, and I drove here today to see if this harvester can be used." Zhao Wenshan pointed to the rice field in front of him and asked, "Who owns this rice?" Can it be harvested? ”

"If you go back to Gongzi, this is the grass people's, and this rice can be harvested now." An old man stood up and replied.

"Can you let me try this harvester?" Zhao Wenshan asked the old man.

"Absolutely! It is an honor for the grass people to be able to help Zhao Gongzi. ”

"Alright, let's get out of the way for the harvester."

Without Wang Haoran's instructions, Zeng Chengyong and Chen Jie excitedly climbed onto the harvester. Zeng Chengyong controlled the harvester to go down to the field, and Chen Jie adjusted the height of the rod and knife edge. The rotating rod pushes the rice seedlings to the harvester, and the cutter in the middle cuts the grain strings, and the grain strings are sent to the mixing drum behind with the conveyor belt, and the rice mixed by the mixing bucket flows out of the small opening next to it and falls into the bucket, and the rice stalk is hooked to the other side by the filter brush. The bottom row of knives cuts the stalks and rows them aside after the stalks have been cut.

Wang Haoran and Zhao Wenshan also took off their shoes and rolled up their trouser legs to watch the rice stirring and falling off behind them, and found that it was not very clean, so they asked Zeng Chengyong to stop and change to a smaller gear to make the stirring speed faster, which solved the problem.

Another big defect is that the paddy field silt is relatively thick, and sometimes it is very laborious to sink a little deeper. But fortunately, the size of the harvester is not large, and if the stronger men take turns pedaling to drive the harvester, the problem is not very big.

It didn't take long for the harvester to harvest nearly half an acre, Zeng Chengyong was too tired at this time, so Zhao Wenshan called two croppers to go up and drive the harvester. This harvester is simple to operate, Chen Jie briefly talked to the two croppers about how to operate, and these two croppers will be able to do it, but they are not so skilled so quickly, and they made a lot of jokes. Other enthusiastic people also happily stepped forward to help, some went to command, some went to load rice, and they were very busy.

"I didn't expect to do it right one time." Zhao Wenshan said with emotion.

"The wheels of the harvester need to be improved, and now the wheels are fine for harvesting wheat." Wang Haoran commented.

"How do you have to change that?"

"Increase the width of the outer ring of the wheel, even if the wheel eats mud a little deeper, the stickiness of the soil will not be too great."

"Makes sense." Zhao Wenshan asked again, "There are not many places that need to be changed, so can we make more harvesters now?" ”

"This is not in a hurry, no matter how much you rush now, it will not take long for these rice to be harvested, we can't make another one in such a short time, it is better to think about how to improve other farm tools!"

"And what do you have a good idea?"

Wang Haoran thought about it, in addition to mechanized farm tools, he really can't think of too many other farm tools that can be improved, and the farm tools used now have no improvement in the next thousand years! It has to be said that the farming technology of the Tang Dynasty almost reached its peak.

"It's much easier to make a threshing machine, it's cheaper, and the people can afford it, so we can make some of it." Wang Haoran thought that cement has not yet been popularized here, and the current threshing floor is rolled out of the flat ground with stones, and the wheat that falls down is easy to mix with sand, so he said, "We can make a threshing floor, this is not a very urgent matter, and when the plant is built here, it can be carried out together with the harvester." ”

"Could it be that the small iron bars that you asked Chen Gongzi to bring from Chang'an before were used to make threshing machines?" Zhao Wenshan asked.

"That's right." During this time, they were all in a hurry to make the harvester, so Wang Haoran didn't tell them about the threshing machine, but the required bearings, gears, and chains had already been brought by Chen Jie from Chang'an, and the wooden body only needed to be made here to install.

Just do it, Wang Haoran left the harvester here for the people to use, and took Chen Jun and them back to make the threshing machine. Nowadays, the farmer's method of beating down the grain is only to prepare a threshing bucket, and hold the rice stalk with both hands and whip it in the threshing bucket, which is not only time-consuming and laborious, but also difficult to avoid the grain flying out of the threshing bucket during the whipping. The threshing machine is made by a person who pedals in front and drives the back drum through a chain, which is covered by a large cover, which only leaves an opening in the back. When using, after the drum is driven, others only need to grab the rice stalk, put the end of the grain string through the opening of the big lid, and flip it a few times to knock the grain clean, not only the speed can be nearly ten times faster, because there is a big lid, there will be no grain flying out and causing waste.
