1984年3月建设部机械管理局在上海召开了混凝土搅拌机升级换代座谈会,同年9至10月在湖南长沙召开了混凝土搅拌机新机型评选、鉴定会。一个以卧轴强制式搅拌机和双锥反转出料自落式搅拌机为主要新机型取代旧的鼓筒自落式搅拌机的浪潮席卷整个行业。我所也不例外,这些年为混凝土搅拌机的更新换代做了一定的工作。我所从1980年初开始着手卧轴搅拌机的研制,在福建省建筑机械厂的合作下,JD200搅拌机于1983年5月通过了部级鉴定,是国内首次研制成功的单卧轴新机型。随后JS350、JD250爬升式、JD250、JD150Ⅰ、
In March 1984, the Machinery Bureau of the Ministry of Construction held a symposium on the upgrading of concrete mixers in Shanghai. From September to October of the same year, a new model selection and appraisal meeting for concrete mixers was held in Changsha, Hunan. A horizontal axis forced mixer and double-cone reversed material discharge mixers are the main new models to replace the old drum-and-drop mixers and sweep the industry. I am no exception. I have done some work for the upgrading of concrete mixers these years. Since the beginning of 1980, we have started the development of a horizontal axis mixer. With the cooperation of the Fujian Construction Machinery Factory, the JD200 mixer passed the ministerial appraisal in May 1983. It is the first single-shaft new model successfully developed in China. Then JS350, JD250, JD250, JD150I,
