一般情况下，全自动混凝土搅拌车搅拌筒的前锥、中锥、后锥长度的参数选取通常情况下大直径取在2100~2300mm之间，如果大直径取在2400mm,全自动混凝土搅拌车在转弯时就会有发飘现象，就有可能造成事故。下面来介绍下它的搅拌筒螺旋线叶片。
Generally, the parameters of the length of the front cone, middle cone and back cone of the mixing drum of the automatic concrete mixer are generally 2100~2300mm. If the large diameter is 2400mm, the automatic concrete mixer will drift when turning, which may cause accidents. Now let's introduce the spiral blades of the mixing drum.
全自动混凝土搅拌车搅拌筒内壁通常设置1对带状的螺旋叶片，相错180°安装，采用左旋叶片。搅拌筒旋转时，2条螺旋叶片被带动作围绕搅拌轴线的运动，实现混凝土的进料、搅拌、卸料作业。搅拌筒按功能可划分为2个区段，尾锥出口段为卸料引导区段，圆柱部分、前锥部分主要用于运输过程中对混凝土的搅动，防止凝固、离析，在卸料时将底部混凝土推出。
The inner wall of the mixing drum of the fully automatic concrete mixer truck is usually equipped with a pair of ribbon shaped spiral blades, which are installed 180 ° staggered, and left-handed blades are used. When the mixing drum rotates, the two spiral blades are driven to move around the mixing axis to realize the concrete feeding, mixing and unloading operations. The mixing drum can be divided into two sections according to its function. The outlet section of the tail cone is the unloading guide section. The cylinder section and the front cone section are mainly used to stir the concrete during transportation to prevent solidification and segregation. The bottom concrete is pushed out during unloading.
圆锥螺旋面是指母线aa′绕圆锥中心轴线、沿筒壁螺旋线轨迹旋转，母线的运动轨迹所形成的圆锥螺旋面。母线为直线的形成直纹螺旋面，母线为曲线的形成非直纹螺旋面。在直纹螺旋面中，母线与圆锥中心轴线正交的，形成直纹正螺旋面；母线与圆锥中心轴线斜交的，形成直纹斜螺旋面。
Conical helicoid refers to the conical helicoid formed by the generatrix aa 'rotating around the central axis of the cone and along the spiral track of the cylinder wall, and the movement track of the generatrix. The generatrix is a straight line forming a ruled helicoid, and the generatrix is a curve forming a non ruled helicoid. In the ruled helicoid, the generatrix is orthogonal to the central axis of the cone to form the ruled helicoid; The generatrix is oblique to the central axis of the cone, forming a ruled oblique helicoid.
你以为搅拌车筒体有两条螺旋线，其实筒体内共设置了9条螺旋线，即前锥部分叶片叶根螺旋线（螺旋线1）和叶顶螺旋线（螺旋线4），圆柱部分叶片叶根螺旋线（螺旋线2）和叶顶螺旋线（螺旋线5），尾锥部分叶根螺旋线（螺旋线3）、叶中螺旋线（螺旋线6和螺旋线8）、叶顶螺旋线（螺旋线7和螺旋线9），其中螺旋线8和螺旋线9为圆柱部分与尾锥部分的过渡螺旋线。
You think there are two helices in the mixer cylinder. In fact, there are nine helices in the cylinder, namely, the blade root helix (helix 1) and the blade tip helix (helix 4) in the front cone part, the blade root helix (helix 2) and the blade tip helix (helix 5) in the cylinder part, the blade root helix (helix 3) in the tail cone part, the blade middle helix (helix 6 and helix 8) Helix at blade top (Helix 7 and Helix 9), where Helix 8 and Helix 9 are transitional helices between cylindrical part and tail cone part.
这些搅拌筒螺旋线的根部和顶部型式、螺旋角决定混凝土在搅拌筒内沿轴向或切向运动的强度，因而也影响着搅拌和卸料的性能，是搅拌筒设计的关键。
The types of the root and top of the spiral lines and the spiral angle of these mixing drums determine the strength of the axial or tangential movement of concrete in the mixing drum, thus affecting the performance of mixing and discharging, which is the key to the design of mixing drums.
