近期有不少車友在咨詢關于混凝土攪拌機攪拌筒的相關知識，小編在查閱資料時發現，這學問可大了，今天，就為大家詳細詳解一下混凝土攪拌機攪拌筒的構成以及工作原理。

Recently, many motorists have been consulting about the mixing cylinder of the concrete mixer. Xiao Bian found that this knowledge is great when looking up materials. Today, I will explain the composition and working principle of the mixing cylinder of the concrete mixer in detail.

混凝土攪拌機攪拌筒一般由前錐、中間筒和后錐三段組成。筒內有兩條間隔180°的，對稱焊接在筒壁上的螺旋葉片，這兩條螺旋線與筒壁形成了螺旋通道，混凝土就沿著這些螺旋通道完成進料、攪拌和卸料等工作。一般前錐、后錐分別采用相同等升角的圓錐對數螺旋片，中間筒一般是圓柱體，一般采用不同等升角的圓柱螺旋葉片。

The mixing cylinder of concrete mixer is generally composed of three sections: front cone, middle cylinder and rear cone. There are two spiral blades symmetrically welded on the cylinder wall with an interval of 180 ° in the cylinder. These two spiral lines form spiral channels with the cylinder wall, along which concrete can complete feeding, mixing and unloading. Generally, the front cone and the rear cone adopt the cone logarithmic spiral slice with the same equal lift angle respectively, the middle cylinder is generally a cylinder, and the cylindrical spiral blades with different equal lift angles are generally used.

混凝土攪拌機的攪拌筒是依靠回轉的筒體帶動兩條螺旋葉片對混凝土進行攪拌和卸料作業的。工作時，攪拌筒繞其軸線轉動，使得混凝土沿攪拌葉片的螺旋線運動，螺旋曲線促使混凝土沿相反的方向移到末端和頂層，這是混凝土攪拌時的主要運動。

The mixing cylinder of the concrete mixer is used to mix and unload concrete by driving two spiral blades with the rotary cylinder. When working, the mixing cylinder rotates around its axis, making the concrete move along the spiral line of the mixing blade. The spiral curve makes the concrete move to the end and top layer in the opposite direction, which is the main movement of concrete mixing.

同時，由于混凝土與筒壁和葉片的摩擦力及其內在的附著力作用，所以在筒體轉動過程中，混凝土達到一定高度后，必在其自重作用下，克服上述摩擦力和內聚力而向下翻跌和滑移。其次在葉片的底部，由于葉片的形狀是曲線型，故混凝土在外力的作用下產生旋轉式的攪動。

At the same time, due to the friction between concrete and cylinder wall and blade and its internal adhesion, when the cylinder rotates, the concrete reaches a certain height, under its own weight, it must overcome the above friction and cohesion and fall down and slip. Secondly, at the bottom of the blade, because the shape of the blade is curved, the concrete will produce rotary agitation under the action of external forces.

由于攪拌筒在連續轉動，所以混凝土所做的是3種運動混合一起的復合運動，即三維攪拌運動。從而使混凝土被均勻的攪拌，保證其勻質性。

Because the mixing cylinder is rotating continuously, the concrete is doing a composite movement of three movements, namely three-dimensional mixing movement. So that the concrete can be evenly mixed to ensure its homogeneity.

攪拌筒結構應簡單，緊湊，輕便，以盡量降低上車自重，這有利于提高混凝土攪拌機的有效裝載容量和相對減少上車的功率消耗。同時，結構的布置要適應底盤的狹長體形和高度限制，應盡量降低攪拌筒和混凝土攪拌機的整車高度和重心，以保證混凝土攪拌機的行使穩定性和通過性，還應有足夠的有效裝載容積，滿足規定的攪拌和裝、卸料性能，在結構上適應運載底盤和攪拌工作的特點等要求。

The mixing drum shall be simple, compact and light in structure to minimize the deadweight of the truck, which is conducive to improving the effective loading capacity of the concrete mixer and relatively reducing the power consumption of the truck. At the same time, the layout of the structure should adapt to the narrow and long shape of the chassis and height restrictions. The height and center of gravity of the mixing drum and concrete mixer should be reduced as much as possible to ensure the running stability and trafficability of the concrete mixer. It should also have sufficient effective loading capacity to meet the specified mixing, loading and unloading performance, and structurally adapt to the characteristics of the transport chassis and mixing work.

攪拌筒的外形比較復雜，沿軸線方向的斷面直徑是變化的。中部直徑大，兩邊逐漸收縮。大容量的攪拌筒則在兩段截錐體間加一段圓柱體，以擴大裝載容積，同時避免攪拌筒中部尺寸過大。更多相關內容就來我們網站http://www.gdfcx.net進行咨詢了解吧！

The shape of the mixing drum is relatively complex, and the section diameter along the axis direction is variable. The middle diameter is large, and the two sides gradually shrink. For the large capacity mixing cylinder, a section of cylinder is added between the two truncated cones to expand the loading capacity and avoid excessive size in the middle of the mixing cylinder.
