The mixing arm is one of the components of the concrete mixer. Many users don't know about it after purchasing and installing it, so they are curious about how to use the mixing arm and what are the functions of the mixing arm. Let's share the functions of the mixing arm of the concrete mixer.

混凝土攪拌機攪拌臂的作用：

Function of mixing arm of concrete mixer:

強制式混凝土攪拌機包括攪拌筒，攪拌筒內裝有攪拌軸，攪拌筒的兩端壁處的攪拌軸上都安裝有一用于清理端壁面的邊臂，兩邊臂之間的攪拌軸上的中點的兩側各安裝有一組螺旋式排布的攪拌臂，兩組攪拌臂在軸向的排布上均自端臂中臂，在旋轉方向的排布均勻分布在端臂中臂，各攪拌臂的頂端都有固定的攪拌葉片，兩邊臂在旋轉方向的排布上分別落后于同側的攪拌臂端臂。

The forced concrete mixer consists of a mixing drum, in which a mixing shaft is installed. A side arm for cleaning the end wall is installed on the mixing shaft at both ends of the mixing drum. A group of spiral mixing arms are installed on both sides of the midpoint of the mixing shaft between the two arms. The axial arrangement of the two groups of mixing arms is from the end arm to the middle arm, The arrangement in the rotation direction is evenly distributed from the end arm to the middle arm. There are fixed mixing blades at the top of each mixing arm. The arrangement of the two arms in the rotation direction is respectively behind the end arm of the mixing arm on the same side.

攪拌臂本身又分為側攪拌臂（有正反之分），中攪拌臂（亦有正反之分），攪拌臂下面是連接的瓦座，連接用攪拌臂高強螺栓4套。上面是安裝的耐磨攪拌葉片，連接用攪拌葉片高強螺栓2套。另外說一下，有的廠家設計有攪拌方粘軸轉環，是間隔安裝在攪拌臂間的分固定和轉動兩種方式。

The mixing arm itself is divided into side mixing arm (positive and negative), middle mixing arm (positive and negative). Under the mixing arm is the connecting tile seat, and the connection is made with 4 sets of high-strength bolts of the mixing arm. There are two sets of high-strength bolts for connecting the blade. In addition, some manufacturers have designed the mixing square shaft rotating ring, which is installed between the mixing arms in two ways: fixed and rotating.

本著實用新型將邊臂在整體攪拌臂布局的旋轉方向的位置后撤，使其落后于同側的攪拌臂組的端臂，這樣在實際工作時，邊臂工作阻力較小、與攪拌筒之間無切磨，使邊臂的耐久度提高，攪拌軸所需驅動力也減小，因此可裝配小功率的電機，使制造成本降低，能耗相應減小。

In the utility model, the position of the side arm in the rotation direction of the overall mixing arm layout is retreated, so that it lags behind the end arm of the mixing arm group on the same side. In practical work, the working resistance of the side arm is small, and there is no cutting and grinding between the side arm and the mixing drum, so that the durability of the side arm is improved, and the driving force required for the mixing shaft is also reduced. Therefore, a small power motor can be assembled, so that the manufacturing cost is reduced, The energy consumption is reduced accordingly.
