本实用新型卧式双旋搅拌机，它主要由电动机1，减速器2，皮带轮系3和增速皮带轮系17组成的传动机构，传动轮5，滚筒6和双流式螺旋叶片组成。传动机构设在支承架14的一端，其增速皮带轮系17与传动轴10联接；其皮带轮系3通过联轴器4与传动轴16联接，由传动轴16将动力传给滚筒6。与传动轴16对称设置有支承轴18，传动轴16和支承轴18分别由支座15固定在支承架14的两侧，每根轴上间隔分布四个橡胶制作的传动轮5(共八个)。滚筒6设在传动轮5上，滚筒6内设置有双流式螺旋叶片，双流式螺旋叶片由内螺旋叶片7和外螺旋叶片8组成，内外叶片相互叠加或交叉按一定规律分布。内螺旋叶片7设在滚筒6的内壁上，断开呈八字形排列；外螺旋叶片8设在主传动轴10上，外螺旋叶片8的顶面可以是断开的，图1所示；也可以是叶片8顶面断开且中部开有与叶片弧面一致的月牙口，图3所示。传动轴10穿过滚筒6并支承在滚筒两端的支座13上，支架13固定在支承架14上。滚筒6两端设有止推盘9，止推盘9内下方设有止推轮11，两个止推轮11用橡胶制成，起目止推作用。滚筒6的前端设有进料口12，尾端设有出料口。其工作原理：由电动机1经减速器2带动皮带轮系3，再通过联轴器4传动传动轴16，传动轴16上的4个橡胶传动轮5同时动作，支承在橡胶轮5上的滚筒6和支承轴18上的橡胶轮同时作旋转运动。滚筒6内分别设置的分段断开的呈一定规律分布的八字形内螺旋断开叶片7，使从进料口12进入的物料分成为两路，一路物料作向前运动，在达到断开处时，物料被抛向传动轴10断开的外螺旋叶片8处，与另一路由增速皮带轮系17联动的传动轴10上分布的螺旋叶片8汇合，一起作旋转推进运动。由于传动轴10上的外螺旋叶片8与滚筒6内螺旋叶片7重叠、交叉并与滚筒6相互旋转的转速差异(时差)的作用，使物料被瞬间抛起、剪切、相互滑移而产生碰撞，对滚和拌和，此后物料又被重组及分开以及又向前推进，周而复始地几次重复此过程。The utility model horizontal double-rotating mixer mainly consists of a motor 1, a reducer 2, a transmission mechanism consisting of a pulley system 3 and a speed-increasing pulley system 17, a transmission wheel 5, a drum 6 and a double-flow spiral blade.
