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.

混凝土搅拌机搅拌臂的作用：

Function of mixing arm of concrete mixer:

强制式混凝土搅拌机包括搅拌筒，搅拌筒内装有搅拌轴，搅拌筒的两端壁处的搅拌轴上都安装有一用于清理端壁面的边臂，两边臂之间的搅拌轴上的中点的两侧各安装有一组螺旋式排布的搅拌臂，两组搅拌臂在轴向的排布上均自端臂中臂，在旋转方向的排布均匀分布在端臂中臂，各搅拌臂的顶端都有固定的搅拌叶片，两边臂在旋转方向的排布上分别落后于同侧的搅拌臂端臂。

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.

搅拌臂本身又分为侧搅拌臂（有正反之分），中搅拌臂（亦有正反之分），搅拌臂下面是连接的瓦座，连接用搅拌臂高强螺栓4套。上面是安装的耐磨搅拌叶片，连接用搅拌叶片高强螺栓2套。另外说一下，有的厂家设计有搅拌方粘轴转环，是间隔安装在搅拌臂间的分固定和转动两种方式。

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.

本着实用新型将边臂在整体搅拌臂布局的旋转方向的位置后撤，使其落后于同侧的搅拌臂组的端臂，这样在实际工作时，边臂工作阻力较小、与搅拌筒之间无切磨，使边臂的耐久度提高，搅拌轴所需驱动力也减小，因此可装配小功率的电机，使制造成本降低，能耗相应减小。

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.
