The structure of the mixing drum shall be simple, compact and light, so as to minimize the self weight of the truck, which is conducive to improving the effective loading capacity of the mixing truck 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 and height limit of the chassis. The height and center of gravity of the mixing drum and the mixing truck should be reduced as much as possible to ensure the driving stability and trafficability of the mixing truck. In addition, it should have sufficient effective loading capacity to meet the specified mixing, loading and unloading performance, and adapt to the characteristics of the carrying chassis and mixing work in the structure. The shape of the mixing drum is relatively complex, and the section diameter along the axis direction changes.

中部直徑，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。

The diameter of the middle part is the largest, and the two sides gradually shrink. For the mixing drum with large capacity, a cylinder is added between the two truncated cones to expand the loading volume and avoid excessive size in the middle of the mixing drum.

一般情況下，攪拌筒的前錐、中錐、后錐長度的參數(shù)選取如下：

Generally, the parameters of the length of the front cone, middle cone and rear cone of the mixing drum are selected as follows:

通常情況下直徑取在2100~2300mm之間，如果直徑取在2400mm,攪拌運輸車在轉彎時就會有發(fā)飄現(xiàn)象，就有可能造成事故。

Generally, the maximum diameter is 2100 ~ 2300mm. If the maximum diameter is 2400mm, the mixer truck will float when turning, which may cause accidents.

上山對大罐車來講太困難，但對自上料攪拌車來講挺簡單。拿2.0方自上料攪拌車來講，科學的設計，鉸接的車身，四驅的應用，爬坡30°穩(wěn)固有力。如果施工點在低洼處，要么它與管道搭配，往下運送混凝土，要么便“親自前往”，定點卸料。

Going up the mountain is too difficult for a large tank truck, but it is very simple for a self loading mixer truck. Take the 2.0m3 self loading mixer as an example. With scientific design, articulated body and 4WD application, it is stable and powerful when climbing 30 °. If the construction site is in a low-lying place, either it is matched with the pipeline to transport the concrete down, or it will "go in person" and unload at a fixed point.

高原對自動上料攪拌車來講也是妥妥沒問題，能為用戶定制符合當?shù)丨h(huán)境的“高原機”，在平原上自動上料攪拌車如何“出色發(fā)揮”，在高原上就能如何“出色發(fā)揮”。

The plateau is also a good place for the automatic feeding mixer. It can customize the "plateau machine" in line with the local environment for users. How to "play well" on the plain and how to "play well" on the plateau.
