近年来,许多不同结构型式的JZ型混凝土搅拌机相继投放市场。我厂与长沙建机所共同研制出新产品JZ350爬翻斗式混凝土搅拌机。在设计中我们就本类机型爬升上料装置普遍存在的一些问题,做了许多探索和实验,解决了部分难题,使本机在技术和结构上独具风格。样机经建设部建筑机械产品质量监督检测中心检测,各项技术性能指标全部达到国家有关标准和国内先进水平,於1987年6月13日在昆明通过技术鉴定。本机爬升倾翻上料装置采用相互独立的二 In recent years, many different structural types of JZ concrete mixers have been put on the market. Our factory and Changsha Construction Machinery Co., Ltd. jointly developed a new product JZ350 Climbing Bucket Concrete Mixer. In the design, we have done many explorations and experiments on the common problems of climbing and feeding devices in this type of machine, solved some problems, and made the machine unique in terms of technology and structure. The prototype was tested by the Construction Machinery Product Quality Supervision and Testing Center of the Ministry of Construction. All technical performance indicators have reached the national relevant standards and domestic advanced standards. They passed technical appraisal in Kunming on June 13, 1987. The machine climbs over and tilts the feeding device and uses independent two
