1. Inclined angle of mixing drum

搅拌筒的斜置角度虽然不是搅拌筒筒体本身的几何参数，但它影响着搅拌筒的有效装载量，搅拌性能，卸料性能，载荷均匀性等，因而也对搅拌筒的几何参数起制约作用，相互影响见表所示。在设计时，必须将搅拌筒的几何参数与其斜置角联系起来考虑，当斜置角度变化时，这时为满足设计要求装载容量，往往需要增加筒体的长度或直径。

Although the inclined angle of the mixing drum is not the geometric parameter of the mixing drum itself, it affects the effective loading capacity, mixing performance, unloading performance and load uniformity of the mixing drum, so it also restricts the geometric parameters of the mixing drum. See the table for the mutual influence. In the design, the geometric parameters of the mixing drum and its inclined angle must be considered. When the inclined angle changes, the length or diameter of the drum often needs to be increased to meet the loading capacity required by the design.

目前，一般搅拌筒的轴线与底盘平面的斜置夹角在10°～20°之间，视搅拌筒的装载容量和上述影响因素以及所选底盘长度而定。搅拌筒斜置角度与有效装载容量一般关系如表所示。

At present, the inclined included angle between the axis of the general mixing drum and the chassis plane is between 10 ° ~ 20 °, depending on the loading capacity of the mixing drum, the above influencing factors and the selected chassis length. The general relationship between the inclined angle of the mixing drum and the effective loading capacity is shown in the table.

2.中锥直径

2. Middle cone diameter

搅拌筒的筒体部分尺寸比例和形状怎样，是一直在研究的问题。据有关实验资料认为：梨形筒体中部具有较大直径，而前锥较短，使搅拌筒中下部的外形接近球体形状为，这时，不仅搅拌效果好，搅拌效率高。

What is the best size proportion and shape of the mixing drum is a problem that has been studied all the time. According to the relevant experimental data, it is considered that the middle of the pear shaped cylinder has a large diameter and the front cone is short, so it is the best to make the shape of the middle and lower part of the mixing cylinder close to the shape of the sphere. At this time, not only the mixing effect is good, but also the mixing efficiency is high.

而且也因搅拌筒适当前移，对合理分配运载底盘前后桥负荷，提高搅拌运输车的装载能力是有利的。但是，搅拌筒中部直径受运载底盘宽度的局限，也受搅拌筒高度对整车稳定性影响的限制，还要考虑交通和运输法规对车辆通过性的有关规定。另外，这一尺寸直接涉及搅拌筒的工作性能和装载量，因此在确定这一直径时，必须综合考虑上述因素。

Moreover, due to the appropriate forward movement of the center of gravity of the mixing drum, it is beneficial to reasonably distribute the load of the front and rear axles of the carrying chassis and improve the loading capacity of the mixing truck. However, the maximum diameter in the middle of the mixing drum is limited by the width of the carrier chassis and the influence of the height of the center of gravity of the mixing drum on the stability of the whole vehicle. The relevant provisions of national traffic and transportation regulations on vehicle trafficability should also be considered. In addition, this dimension is directly related to the working performance and loading capacity of the mixing drum. Therefore, the above factors must be taken into account when determining this maximum diameter.

3.锥体锥角

3. Cone angle

筒体两端锥体的锥顶角度一般都与其斜置角度相对应，相差无几，常控制在10°~20°之间，一般使前锥下母线、后锥上母线平行于汽车大梁，这样是为保持搅拌筒在斜置时顶部平直和一定的卸料性能，锥顶角及其主要影响因素的相互影响见表所示。也使整车更加协调、美观。

The cone top angles of the cones at both ends of the cylinder generally correspond to their oblique angles, which are almost the same. They are often controlled between 10 ° ~ 20 °. Generally, the lower bus of the front cone and the upper bus of the rear cone are parallel to the truck girder. In order to maintain the straightness and certain unloading performance of the top of the mixing cylinder when it is oblique, the interaction of the cone top angle and its main influencing factors is shown in the table. It also makes the whole vehicle more coordinated and beautiful.

4.筒体沿轴线方向的长度

4. Length of cylinder along axis

筒体沿轴线方向的长度应参考载重量，由己确定的中部直径、锥顶角等几何参数用计算辅助设计或手工绘图方法求得，但这一尺寸受选定汽车底盘长度的限制，应根据搅拌装置各组成部分（如水箱，专用发动机等）在上车的布局情况和支承点进行调整。轴线方向长度及其主要影响因素的相互影响见表所示。

The length of the cylinder along the axis direction shall refer to the load capacity and be obtained from the determined geometric parameters such as the maximum diameter in the middle and the cone apex angle by means of calculation aided design or manual drawing. However, this dimension is limited by the length of the selected vehicle chassis and shall be adjusted according to the layout and support points of each component of the mixing device (such as water tank, special engine, etc.) on the vehicle. The length of axis direction and the interaction of its main influencing factors are shown in the table.
