? Back home that day, I met a combine harvester harvesting wheat in the endless golden wheat field. Seeing this scene, I can't help but think of Wang Xiliang, the former deputy director and model worker of Wanrong County Thresher Factory, who made outstanding contributions to the development of "Dongfanghong" airflow cleaning thresher in Wanrong County.

in the late 196s, I was lucky enough to recruit workers and came to Wanrong County Thresher Factory. At that time, the thresher factory was a famous brand enterprise in the whole region, and Wang Xiliang was the backbone technician in the factory. The thresher he researched and invented greatly improved the efficiency of wheat warehousing at that time. However, he was not satisfied, because the thresher made the wheat bid farewell to the history of wheelbarrow grinding, but the manpower use was still "swarming", and the emerged wheat was mixed with impurities such as wheat straw. Follow-up homework is still cumbersome. In order to solve this problem, Wang Xiliang and the research team stayed up all night, thinking hard, racking their brains, drawing paper, making plans and studying repeatedly. Later, Wang Xiliang finally developed the first Dongfanghong No.1 thresher according to the principle that the whirlwind in the field spins away frivolous things in summer, leaving heavy things behind, and achieved the effect of separating impurities from wheat bran and straw for the first time. With the new technology, the wheat is clean and can be directly delivered to the public grain after threshing. This invention soon caused a sensation. During this period, in order to transform this new technology into productivity as soon as possible, Wang Xiliang stayed in the "belly" of the thresher for an hour or two every time, and every time he came out for air, he saw that his work clothes were soaked with sweat. When eating, I become crazy because I think about problems, and I often stand in a daze with my rice bowl. Sometimes the principle that can't be figured out during the day suddenly wakes up in the dead of night. He immediately gets up, takes a flashlight to the workshop and gets into the machine for careful analysis. In the most critical period of the development of Dongfanghong No.3 airflow cleaning thresher, the old father was ill and admitted to the hospital. After hearing the news, he sent the old man to the hospital, let his sons Guanlin and Guannong go to bed to pay their respects, and quietly left the hospital and returned to the factory to continue his research and development work. Even after his father died, he led several disciples to fight in the workshop a few days before his burial. He didn't go back to the wake until the old man was buried tomorrow. With the concerted efforts of Wang Xiliang and everyone Qi Xin, the airflow cleaning thresher in Wanrong County was constantly upgraded. In 1969, the back compound thresher was manufactured, that is, the airflow cleaning thresher was installed on a tractor, and it began to work in the field, and the wheat harvest was completed at one time. The invention and successful use of airflow cleaning thresher in Wanrong County caused a sensation in China, and many media such as People's Daily and Shanxi Daily reported it quickly. At the national mechanical and electrical innovation work conference, Dongfanghong No.3 airflow cleaning thresher in Wanrong County was rated as a promotion project. Then, Dongfanghong No.3 air cleaning thresher also went to Japan and Germany for an international technical exchange exhibition on behalf of the country. The relevant departments of the United Nations also selected it as a teaching material for science and technology, and made it into a documentary for publicity in various countries. Moreover, Wang Xiliang's four or five textbooks on airflow cleaning thresher have been printed in large quantities by several publishing houses. In the following years, the Dongfanghong airflow cleaning thresher was not only active in Wanrong and Sanjin, but also orders from all over the country poured in. For several years, dozens of Dongfanghong airflow cleaning threshers were "married" from Wanrong County every year.

Wang Xiliang was born in Zhang Weng Village, Nanzhang Township. Since he was a child, he liked to play with small things and make small toys. When he grew up, he went to Lanzhou Chemical Fertilizer Plant as a worker. In 1966, he returned to his hometown and returned to Jiedian Town General Machinery Factory. After he developed the first thresher, he was not satisfied with the status quo. On the premise of no reference materials, no technical data, no professional lathes and lack of funds, he relied on the unique spirit of being a man of honor and stepping up one step a year, relying on the Wang Jinxi-style spirit of "if conditions permit, conditions should be created", and created an air-flow cleaning thresher that won the admiration of the national agricultural machinery technology community, which also provided valuable for later more advanced harvesters. As long as you have paid for the people, the party and the country will never forget. Wang Xiliang was successively elected as deputy director of Wanrong County Thresher Factory, alternate member of Wanrong County Party Committee, member of Wanrong County People's Congress Standing Committee, advanced worker of Daqing in China and national model worker. He studied technology with one track mind all his life, and returned to the village after retirement. According to the needs of farmers, he also researched and produced rural practical small machinery such as peanut sheller and sweet potato polisher. Until he died at the age of 82 in 21, he finished his life of loving mechanical technology.

? In those years when I worked in the thresher factory, I was deeply impressed by Wang Xiliang's perseverance and never give up until I reached my goal. Following this master, I not only learned to do things, but also learned to be a man, which benefited a lot. Over the years, I often think of this old man who has done something for Wanrong County and won honor. Especially during the summer harvest, when I see the combine harvester active in the field, I can't help but think of my years in the thresher factory and master Wang Xiliang.
