1971年,只有15岁的周明忠被招工到县第一建筑公司当泥瓦工。繁重的人工体力劳动——和灰、搬砖、砌墙、抹灰,常常累得他腰酸背痛。他决心研制出一种省工省时、节材省能的墙体建筑机械,造福于当代建筑工人。从1974年开始,他广泛收集国内外建筑资料,自费订阅了《建筑机械化》、《机械设计》、《电器控制》、《机械加工》等15种刊物,自学了初中、高中、大学的数学、物理、电学等课程。经过15年100多次试制失败的挫折,终于研制成功我国第一台墙体浇筑砌筑抹灰多用机(见附图)。从
In 1971, only 15-year-old Zhou Mingzhong was recruited to the county’s first construction company as a mason. The heavy manual labor - gray, brick, wall, plaster, often tired his back pain. He is determined to develop a wall construction machine that saves time, material, and energy, benefiting contemporary construction workers. Since 1974, he has extensively collected domestic and foreign construction materials and has subscribed to 15 publications such as “Mechanization of Construction”, “Mechanical Design”, “Electrical Control”, and “Machinery Processing” at his own expense, and he has studied mathematics in junior high school, high school, and university. Physics, electricity and other courses. After fifteen years of failed trial production over 100 years, it has finally succeeded in developing the first multi-purpose machine for pouring and masonry plastering in China (see attached figure).
