国家专利号为89217860·4。该项新技术成功地解决了JD卧轴型系列搅拌机搅拌部分被骨料卡死;倾翻机构易坏;搅拌筒两端面漏浆;上料系统易坏和不便操作等技术的难关。该技术于1991年12月28日通过四川省建筑工程质量监督检验站检测,各项指标均优于国家标准。采用该技术的机器兼有自落式、强制式和灰浆机三种机型的特性,能搅拌干硬性、塑性混凝土和轻骨料混凝土,也能搅拌各种沙浆、灰浆和硅酸盐混合
The national patent number is 89217860·4. The new technology has successfully solved the difficulties of the JD horizontal shaft type mixer, where the stirring part is jammed by aggregates, the tipping mechanism is easy to be damaged, the two ends of the mixing drum are leaking, and the feeding system is fragile and inconvenient to operate. The technology was tested on the Sichuan Provincial Construction Engineering Quality Supervision and Inspection Station on December 28, 1991, and all the indicators were better than the national standards. The machine adopting this technology combines the features of three types of self-dropping, forced and mortar machines. It can mix dry hard, plastic concrete and light aggregate concrete, and can also mix various mortars, mortars and silicates.
