Now, through the parameterization and optimization design of the tank helix of the agitator, the tank formed after the optimization process is tested and tested. The results show that the dimensional accuracy of the tank is significantly improved and meets the requirements, and the discharge rate of the tank is also significantly improved, meeting the relevant standards. Next, we will talk about the design principles of other factors affecting the tank of the mixer.
1. Inclined angle of mixing drum
Although the inclined angle of the mixing cylinder is not the geometric parameter of the mixing cylinder itself, it affects the effective loading capacity, mixing performance, unloading performance, load uniformity, etc. of the mixing cylinder, and thus restricts and interacts with the geometric parameters of the mixing cylinder. In the design, the geometric parameters of the mixing drum must be considered together with its inclined angle. When the inclined angle changes, in order to meet the design requirements for loading capacity, it is often necessary to increase the length or diameter of the drum.
2. Middle cone diameter
It is always a problem to study how to make the size proportion and shape of the mixing cylinder. According to the relevant experimental data, the pear shaped cylinder has a large diameter in the middle, while the front cone is short, so that the shape of the lower part of the mixing cylinder is close to the shape of a sphere. At this time, not only the mixing effect is good, the mixing efficiency is high, but also due to the proper forward movement of the center of gravity of the mixing cylinder, it is beneficial to the reasonable distribution of the load on the front and rear axles of the chassis, and the improvement of the loading capacity of the fully automatic mixer.
However, the large diameter in the middle of the mixing drum is limited by the width of the carrier chassis, and also by the influence of the height of the mixing drum's center of gravity 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, so the above factors must be comprehensively considered when determining this large diameter.
3. Cone angle
The cone top angle of the cones at both ends of the cylinder generally corresponds to its oblique angle, which is almost the same. It is usually controlled between 10 ° and 20 °. Generally, the lower bus of the front cone and the upper bus of the rear cone are parallel to the truck girder. This is to keep the top of the mixing cylinder straight and have a certain discharge performance when it is tilted. The interaction between the cone top angle and its main influencing factors also makes the whole vehicle more harmonious and beautiful.
4. Length of cylinder along axis
The length of the cylinder along the axis direction shall refer to the load capacity, and the geometric parameters such as the determined large diameter in the middle, cone top angle, etc. shall be obtained by calculation aided design or manual drawing method. However, this dimension is limited by the length of the selected automobile chassis, and shall be adjusted according to the layout and supporting points of each component of the mixing device (such as water tank, special engine, etc.) on the upper vehicle. The interaction between the axis direction length and its main influencing factors.
