At present, there are many kinds of self loading mixers on the market. In addition to the conventional automatic loading, mixing, unloading and other functions, in terms of model design and practical functions, all manufacturers are working hard to develop more efficient models. Today, based on my personal experience, let's talk about the advantages and disadvantages of model design in practical use, Sincerely invite correction!

一. 先说说驾驶室和搅拌罐同位位移的设计方向，驾驶室和搅拌罐一体同位位移的设计，在一定程度上有利于驾驶员更好的观察出料口在卸料时的位置和出料量，提高了准确率，对出料的控制可以达到一个比较精确的的控制。但同时弊端也是不容小视的，一方面，驾驶室跟随罐体同步转动，驾驶员就处于一个来回运动的状态下，而且是沿着一个半径大概三米左右的圆形轨迹在运动，很多情况下视线范围都是一个悬空的状态，在这样的情况下，驾驶员就很容易出现疲劳，还有一个很重要的问题，这样同位位移的设计，驾驶室是一体安装在罐体上的 ，无形中也加剧了底部转盘的承受强度，对转盘的长期运转，无疑是一个很大的隐患。如果仅仅是要提高卸料准确度的需求，可以在搅拌车后视镜处安装摄像头，在驾驶室同步显示出料情况，相信同样可以这个问题。

1、 First, let's talk about the design direction of the same displacement of the cab and the mixing tank. The design of the integrated same displacement of the cab and the mixing tank is conducive to the driver to better observe the position and discharge volume of the discharge port during discharge to a certain extent, improve the accuracy, and achieve a more accurate control over the discharge control. But at the same time, the disadvantages should not be underestimated. On the one hand, when the cab rotates synchronously with the tank, the driver is in a state of back and forth movement, and is moving along a circular track with a radius of about three meters. In many cases, the line of sight is in a suspended state. In such cases, the driver is prone to fatigue, There is also a very important problem. For the design of the same displacement, the cab is integrally installed on the tank, which virtually intensifies the bearing strength of the bottom rotary table, which is undoubtedly a great hidden danger for the long-term operation of the rotary table. If it is only the need to improve the unloading accuracy, a camera can be installed at the rear-view mirror of the mixer truck to synchronously display the discharge in the cab. I believe this problem can also be solved.

二.上料铲斗和罐体是否一体的设计方向。现在很多生产厂家都慢慢改进了上料铲斗的安装方式，开始把上料铲斗和罐体分离，铲斗方向固定在与驾驶室平行的地方，而不再是安装在罐体底盘上，这样改进的好处是显而易见的，一方面 上料时铲斗的方向本身就是需要和驾驶室同步，才能进行铲料。另外，铲斗和大臂的重量也是不容忽视的问题，长期安装在罐体底盘上，重力的方向体现在底盘上，始终是作用在转盘的一个点上，这样，对底盘的伤害也是很大的。

2、 The design direction of whether the loading bucket and can body are integrated. At present, many manufacturers have slowly improved the installation mode of the loading bucket and began to separate the loading bucket from the can body. The bucket direction is fixed in a place parallel to the cab rather than installed on the can chassis. The benefits of this improvement are obvious. On the one hand, the direction of the bucket itself needs to be synchronized with the cab before shoveling. In addition, the weight of bucket and boom can not be ignored. It is installed on the tank chassis for a long time, and the direction of gravity is reflected on the chassis, which always acts on a point of the turntable. In this way, it will also cause great damage to the chassis.

三.前期一些厂家采用的是前四后二的轮胎组合，这样的设计，外行看来，确实是提高了整车的承载能力，不过从事混凝土行业的人都知道，搅拌车的工作环境绝大多数都是比较复杂崎岖的路况，如果是前四后二的轮胎组合，相邻的两个轮胎之间，难免会挤进一些石块之类的异物，而在通过坑洼道路时，载重瞬间加大，对轮胎的破坏是不可逆的，严重了直接报废 ，这个情况玩过大车或是维修的朋友应该是见过很多的。

3、 In the early stage, some manufacturers used the tire combination of the first four and the second. From the perspective of laymen, this design really improves the bearing capacity of the whole vehicle. However, people engaged in the concrete industry know that most of the working environment of the mixer truck is relatively complex and rugged road conditions. If it is the tire combination of the first four and the second, between the two adjacent tires, It is inevitable that some foreign matters such as stones will be squeezed in. When passing through a pothole Road, the load will increase instantaneously, and the damage to the tire is irreversible. If it is serious, it will be scrapped directly. Friends who have played with a cart or repaired should have seen a lot of this situation.
