Yu Qiaqing, who had not spoken, suddenly clapped her hands after the game: "What a good machine!" ”

Li Shuhua said with a smile: "Our harvester also has an advantage, that is, the main body is a wooden structure. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 Info is easy to manufacture, inexpensive, suitable for large-scale promotion, and affordable for farmers with moderate households. ”

Yi Peiji laughed and said: "This thing is very good, I will urge the Ministry of Agriculture and Mining to quickly promote this machine to rural areas across the country." ”

Zhou Hexuan said: "We also need the help and support of the Chamber of Commerce. ”

"Yu will definitely do his best." Yu Qiaqing immediately expressed his position.

Yu Qiaqing's current identity is the vice president of the All-China Federation of Chambers of Commerce and the president of the Shanghai General Chamber of Commerce.

Among the representatives of the merchants, a middle-aged man suddenly said: "This kind of machine is of great help to the peasants, and I would like to introduce it to Shaxian!" ”

It was Huang Erkang, vice president of the Shaxian Chamber of Commerce, who spoke, like Yu Qiaqing, who was also born as a poor apprentice and developed by his own efforts step by step.

Huang Erkang started to get involved in the candy business last year, and this year he came to Shanghai to open a branch (the head office is in Fuzhou), and next year he even opened a branch in Tianjin. When Zhou Hexuan ran to invite Yu Qiaqing, Huang Erkang followed by to see the excitement.

Huang Erkang's business credo is to value the poor, and last year a child came to his store to buy white sugar, and only bought a copper plate of sugar. The clerk thought that the children were buying too little, so they said that there was no candy to sell.

When Huang Erkang heard this, he immediately stopped the child and sold him the sugar. Afterwards, he said to the clerk: "On a hot day, asking a child to buy a copper plate of candy must be poor and urgent." You think that the business of a copper coin is small and troublesome, so it can be seen that you can't do business. You'd better find another job. ”

So Huang Erkang dismissed the clerk and set a store rule: if anyone wears straw shoes to enter the store, the shopkeeper should personally send tea and cigarettes to show his cordiality; If someone wears leather shoes into the store, the apprentice will give tea and cigarettes to be polite.

This is a kind man.

"I've got the business in Ganzhou!"

"I can't call the shots elsewhere, I order 500 harvesters on behalf of Yiyang!"

"Anqing, we want Anqing too."

“……”

Merchants promised that they clearly saw the value of the harvester and did not want to miss out on this good business that would make money and benefit the people.

However, there are also some profiteers who stare at the machine and want to find a carpenter to imitate the knockoff.

The main body of this thing is a wooden structure, which is very easy to imitate. It is also difficult to grasp the density of the detachator, which is too dense and easy to jam the ears, and too sparse and unclean threshing.

Zhou Hexuan smiled and said, "Don't be in a hurry, let's have another competition." ”

Soon he found two more similar rice fields, and this time Changgong was already familiar with the machine, and the rice was harvested quickly. The four long-term workers who used the traditional method have been working for an hour continuously, and their physical strength has decreased slightly, and the rice harvesting speed is not as fast as before.

Finally, through timed measurement, the ratio of harvesting efficiency between machines and traditional methods is 1:2.8, which means that one person can almost equal the productivity of three people.

And the biggest advantage of the machine is labor-saving, the longer the working time, the more the effect can be reflected.

In the traditional way of harvesting, the farmer has to work all day long, sleeping with both arms sore and sore arms, and the machine threshing is much easier.

In the afternoon of the same day, Zhou Hexuan discussed the details of the cooperation with the businessmen.

In the end, the result of mutual negotiation was that the merchant was responsible for the production and sales, and one percent of the selling price of each machine was used as royalties. The term of the patent is five years, after which no fee is charged.

The patent fee of one percent is very low, but it was already rare during the Republic of China. Even so, it is estimated that some businessmen have misrepresented the number of sales in order to evade royalties.

There's no way, the national situation is like this, so I can only pinch my nose and admit it.

Li Shuhua is very satisfied with this, and he thinks that even if he does not charge a penny of patent fees, it is good to benefit the country and the people.

Not only did the All-China Chamber of Commerce agree to cooperate, but the Ministry of Agriculture and Mines also agreed to help with the promotion. Yi Peiji even made a decision on the spot to reward the scientific research department of Peking University with 500 yuan to reward them for their contribution to the agricultural development of the Republic of China.

Li Shuhua and the accompanying students of the Research Department of Peking University were very excited, as were the reporters.

Not only did Ta Kung Pao report on this in detail, but even the Declarations and News did not hesitate to praise them.

The "Declaration" devoted a full page to this news:

"The famous scholar Zhou Hexuan is known for his novels and academic monographs, but he is also an inventor. Zhou's underwear is now popular in China, and the underwear was invented and improved by Mr. Zhou Hexuan......

Recently, the 'human harvester', which was designed by Mr. Zhou and designed and developed by the Scientific Research Department of Peking University, was tested in the rice fields of Jinshan. There were many visitors to the site, including Yi Peiji, Minister of Agriculture and Mining, and Yu Qiaqing, President of Shanghai General Chamber of Commerce......

Two competitions were arranged on the same day, and at the beginning, the harvest progress was lagging behind due to the lack of familiarity with the machine by the long-term workers. However, in only two quarters of an hour, the machine overtook human power...... The second competition ended with a big victory for the machine. According to scientific measurements, the efficiency of the machine is three times that of human labor......

Westerners are ahead of the world in science and technology, modern inventions emerge one after another, and the steam engine has created the industrial age. And our people don't have the spirit of invention? No, the four great inventions of ancient times all came from China and made great contributions to the development of human society and science. Today's manpower harvester also proves this truth, our people have wisdom and intelligence, and they are not inferior to Westerners......

According to Mr. Zhou Hexuan, the human harvester invented this time is mainly used for harvesting wheat and rice. Because there are many hills and rivers in southern China, large machinery is not suitable. Combined with China's special agricultural geographical environment and the current situation of underdeveloped basic industry in China, the main body of Peking University's human harvester is wooden, which is light and easy to use, but also cheap and easy to make. This machine can be used in the southwest mountains, and is also suitable for the water towns in the south of the Yangtze River. Traditional carpenters can also imitate themselves, which is a great invention and creation that suits the national conditions. ”

Due to the competition of Shanghai newspapers, other newspapers also reprinted it, and the fame of the human harvester quickly opened.

It's useless to brag about it, and the news photos plus the results of the competition make the impression more intuitive for the average reader. The 1 to 3 production efficiency is proved to be excellent and convincing by scientific data.

Countless readers have praised it, but there are also dismissive ones.

These people believe that the human harvester invented by Zhou Hexuan and Peking University is just a simplified version of the Western combine harvester, and there is nothing commendable. People's combine harvesters are convenient, fast and tall, and China's broken harvester still has to be carried and trampled by manpower, which still belongs to the category of traditional agricultural tools.

Regardless of whether it is in favor or against, Zhou's harvester (also known as Peking University harvester) has quickly become popular.

There are even traditional craftsmen who use their brains to replace iron buckles with bamboo chips and hemp rope instead of belts, imitating "pure natural" knockoffs. The whole machine was disassembled, and there was no iron tool on the body, not even an iron nail, because people use mortise and tenon structures.

By the mid-30s, human harvesters were already blooming everywhere in rural China. Due to the different regions and crops, various versions of imitations appeared. This machine was used until the 21st century, when it was replaced by a new agricultural harvester, which finally ended its historical mission.

Funnily enough, because most of the imitations are all-wooden structures, many people in later generations thought that this kind of machine belonged to traditional agricultural tools. One professor even made a big joke by writing a paper touting traditional Chinese farming tools through a human harvester, believing it to be the ancestor of the modern combine harvester.
