S1122型辗轮混砂机与S1322型辗轮转子混砂机,均由山东工业大学和济南铸造锻压机械研究所联合设计,并由青岛第四铸造机械厂试制生产。该两种样机于1986年12月2至3日在青岛市通过了省级鉴定。该样机的结构特点:减速器采用一般齿轮传动,便于制造;主电机与减速器采用液力偶合器联接,具有负载平稳起动和超载保护作用;减速器与主轴的联接,选用能承受较大负荷的链条联轴节,便于机器安器维修;采用抽屉式卸砂门,解决了混辗时的漏砂问题;辗轮
S1122-type roller wheel mixer and S1322-type roller wheel mixer, both by Shandong University of Technology and Jinan forging Machinery Research Institute jointly designed by the fourth casting plant in Qingdao trial production. The two prototypes passed the provincial appraisal in Qingdao City from December 2 to December 3, The structural features of the prototype: the reducer with general gear drive, easy to manufacture; the main motor and reducer using hydraulic coupling, with a smooth start and load overload protection; reducer and the spindle connection, choose to withstand greater load Chain coupling, easy machine maintenance; drawer-type unloading door to solve the problem of missing sand mixed roller; Roller
