my country's first place!Shao Yaojian, an agricultural engineering expert who drives the wheel tractor into the paddy field

Older generation of scientists style

Faced with the "tractor paddy field problem" that needs to be solved, he took the lead in conducting in -depth research on the tractor's impeller, especially in the water field tractor drive wheel. The first batch of graduate students recruited Luo Xiwen, Zhang Tailing and Chao Yinggang achieved the good story of "Shao's Three Jie". He is one of the founders of the School of Engineering of South China Agricultural University and Shao Yaojian, the first expert in my country to drive wheel tractors into the paddy field. Shao Yaojian actively expanded the field of ground machine systems and made outstanding contributions to my country's agricultural mechanization research and education. The outstanding talents he cultivated have further promoted the innovation and development of my country's agricultural machinery and chemicals.

Counter a difficult, dedicated to scientific research

In February 1927, the eldest son of Dr. Shao Yaonian of Lingnan University was born. Shao Yaojian, born in Shuxiangmen's home, was influenced by his father. Since he was a child, he became a person who contributed to the country. Shao Yao was transferred to a professor of South China Agricultural College after 1952, and was responsible for the teaching of agricultural knowledge. Shao Yaojian, who took his father as an example, was influenced by agricultural related knowledge since he was a child. He had recognized the importance of agricultural machinery since he was a child.

In October 1949, the People's Republic of China was established, and Vientiane was updated. This year, Shao Yaojian joined the work after graduating from Sun Yat -sen University's College of Engineering. Then he was transferred to South China Agricultural College (now South China Agricultural University) in 1952, and his scientific research was launched.

At that time, tractors developed by the United States and other countries were mainly dry land, while most of the cultivated land in China was mostly paddy fields, and it was difficult for dry land tractors to play a role in the paddy field. Shao Yaojian was soberly aware that research was not done for research, but to solve the problem. In the face of the "tractor paddy field problem" that needs to be solved urgently, he took the lead in conducting in -depth research on the drag wheel, especially the drag wheel.

Paddy field tractor No. 5 curved impeller

In 1958, Shao Yaojian's research for many years of the paddy field tractor driving wheel finally made breakthrough progress, invented the paddy field tractor No. 5 surface impeller, so that the wheel tractor can operate in the water field, becoming the earliest expert in my country to successfully drive the wheel tractor into the paddy field. It has created the precedent of my country's ground machine system in South China and laid the foundation for the research on ground machine system research in South China. This achievement has been promoted and applied in 13 provinces and cities in southern my country, and has achieved huge economic benefits. Therefore, he won the first prize of Guangdong's agricultural tools for invention and the first prize of the Guangdong Provincial People's Government's Agricultural Wealth Reform. In the same year, he designed the van grain dryer to win the second prize of the Guangdong Provincial People's Government's Agricultural Tool Reform. He also won the first prize and third prize of the Ministry of Agriculture Science and Technology Progress Award.

As a scientific researcher, he is knowledgeable, his mind is agile and good at observing. In the 1960s, once he conducted a tractor test in the field. When observing the interaction of the tractor wheel and the soil, he was inspired by the interaction of the tractor drive wheel leaves with the soil. Principles to analyze? This idea opened Shao Yaojian's scientific research ideas. Based on the gear meshing principle in the mechanical principle, he deeply studied how to use the meshing effect of wheel leaves and soil to obtain a greater driving force. The relationship between wheel leaves and soil, and thus derives the entire set of computing formulas for calculating the geometric parameters of the paddy field. The research results were published at the international seminar of ISTVS ground machine system in Canada in 1979. Essence

From the 1970s to the 1980s, Professor Shao Yaojian led the scientific research team to conduct in -depth research and dynamics of the paddy field drive wheels. The paper published during the period, "Research on the Dynamics of Paddy Fields", systematically summarized the research results of the water field tractor driving wheel since the 1970s.

Teach according to their aptitude, cultivate the beams

In 1978, graduate enrollment was resumed, and each discipline gradually resumed construction. Shao Yaojian deeply realized that the historical moment of the country's revival of the country is coming. A large number of outstanding young talents are required to devote themselves to the construction of agricultural mechanization. He actively responded to the country's call to recruit graduate students in agricultural mechanization. In 1979, he recruited Luo Xiwen, Zhang Tailing and Qu Yinggang.

During the Edinburgh International Conference in 1988, [Shao Yaojian (second from left) with his disciple Luo Xiwen (first from right), and Qu Yinggang (first from the left)]

Shao Yaojian has strict requirements on the students. Because he was born in engineering, his requirements for the foundation of mathematics knowledge were even more strict. Door.

According to the characteristics of the actual work experience of Luo Xiwen, Zhang Tailing, and District Yinggang, Shao Yaojian was taught due to the characteristics and formulated a training plan based on the characteristics of the students. Every student has the field of goodness. Shao Yaojian does not impose his ideas to the students. Instead, he follows the temptation, conducts inspiring teaching, and focuses on the guidance of scientific research thinking.

Carry forward to provide opportunities for learning for young scholars. When Shao Yaojian was the mentor, he often took students to participate in various academic conferences to develop the students' vision. Luo Xiwen has still retained the papers of the national academic conference with his tutor to Kunming in 1983. The thick stack of yellowish paper is full of the teacher's expectations and the students' respect and gratitude to the teacher.

In terms of graduate education, Shao Yaojian guided 7 doctoral students and 17 master's degree students throughout his life, including 1 foreign student, and many disciples have achieved great achievements in their respective fields. Among them, the first graduate students Luo Xiwen, Zhang Tailing and Chao Yinggang have achieved the story of "Shao Sanjie" (District Yinggang, former dean of the School of Engineering, South China Agricultural University, member of the Ninth and Ten National Committee of the Chinese People's Political Consultative Conference. , The former Deputy Director of the Education Department of Guangdong Province. Luo Xiwen, academician of the Chinese Academy of Engineering). Lu Huazhong, the dean of the Provincial Academy of Agricultural Sciences, was the first doctor of Shao Yaojian. Pioneering and innovation, building a discipline

In May 1958, according to the country's needs for agricultural mechanization talents, the South China Agricultural College was based on the agricultural machinery teaching and research group of the agricultural department, and the agricultural mechanization major was added in the agricultural department. One of the teaching and research teams, he assisted Associate Professor Wu Yishun for various preparations.

Shao Yaojian led the workers to make technological innovation with teachers from the factory, changed the old -style belt transmission to the gear transmission, improved the processing accuracy, and also made the self -produced gear rolling machine. The venue also provides teachers with a place for teaching and production. The teachers of the teaching and research team actively participated in the construction of agricultural weapon factories. For example, Mr. Chen Jinle designed and manufactured the transformer and temperature control screen of the heating equipment salt furnace.

In terms of discipline construction, Shao Yaojian focused on the construction of research directions, discipline platforms and scientific research teams. According to the needs of socio -economic development, subject foundation, and the research advantages of teachers, Shao Yaojian determines the three directions: three directions of the construction of ground machine system mechanics, agricultural machinery and agricultural energy. In order to strengthen discipline construction and scientific research, Shao Yaojian personally organized and built the construction of the soil groove laboratory and the solar drying laboratory. These two laboratories were the earliest professional laboratories in China at the time. Studies provide advanced test conditions.

Shao Yaojian led the Department of Agricultural Engineering of South China Agricultural University to actively participate in and promote the construction of agricultural engineering disciplines in my country. Under the leadership of Shao Yaojian, the construction of the Agricultural Engineering Discipline of South China Agricultural University has ranked among the forefront of the national agricultural engineering discipline. Provincial key disciplines were rated as national key (cultivation) disciplines in 2007. Agricultural Engineering Discipline was selected as key disciplines in Panfeng, Guangdong Province in 2012, and ranked 5th and fourth in the national agricultural engineering disciplines in the third and fourth round of disciplines in 2012 and 2016.
