工作時發動機通過取力傳動軸、液壓傳動系統及齒輪減速器驅動攪拌筒轉動。攪拌筒正轉時進行攪拌或裝料，反轉時卸料。攪拌筒的轉速和轉動方向由操作人員根據車的工作狀態，通過改變液壓馬達的斜盤角度來實現。
Work when the engine through PTO shaft, hydraulic transmission and gear reducer drive mixing drum rotates. Stirring or mixing tube are charging the turn, when the reverse discharge. Speed and direction of rotation of the mixing tube by the operator depending on the vehicle operating state by changing the swash plate angle of the hydraulic motor to achieve.
大部分攪拌筒都采用梨形結構，是一個變截麗面不對稱的雙錐體，外形似梨，從中部直徑最大處向兩端對接著一對不等長的截頭圓錐，底段錐體較短，端面封閉；上端錐體較長，端部開口，低端面上安裝著中心轉軸，上段錐體的外部有一條環形滾道。
Most of the mixing tube are used pear-shaped structure is a variable cut Korea faces an asymmetric double cone shape like pears, from the middle to the largest diameter at both ends and then one pair of unequal length of a truncated cone, cone bottom segment body short, closed end; upper cone is longer, open-ended, low surface mounted center shaft, the outer upper section has an annular cone raceway.
攪拌筒縱向沿內壁對稱地焊接著兩條連續的帶狀螺旋葉片，當攪拌筒轉動時，葉片被帶動作繞攪拌筒軸線的螺旋運動，對混凝土進行攪拌或卸料。為提高攪拌效率，筒內還裝有輔助攪拌葉片。
Longitudinally along the inner wall of the mixing tube welded two symmetrically continuous strip helical blade, when mixing drum rotates, the blades are driven around the mixing tube axis as a spiral movement, stirring or unloading of concrete. To improve the stirring efficiency, the cylinder is also equipped with an auxiliary agitating blade.
