The blades of concrete mixer truck are an important part of the whole mixer body. They directly participate in the mixing process of concrete by concrete mixer truck. They are often damaged and faulty in the process of use. The rationality and correctness of the installation and use of concrete mixer blades will have a great impact on the mixing performance and mixing efficiency of the whole equipment of concrete mixer.

在混凝土搅拌车的安装和使用过程中涉及各种各样的参数，而混凝土搅拌车叶片的安装角度是一个基本的参数，对搅拌车叶片和整个搅拌机的工作性能几乎是决定性作用。而搅拌车的安装角度与搅拌机的其他安装和运行参数相互联系相互作用，在混凝土搅拌车叶片的安装和使用过程中除了要考虑到安装角度外还应当结合其他混凝土搅拌车安装和运行参数综合考虑。

Various parameters are involved in the installation and use of concrete mixer, and the installation angle of concrete mixer blade is a basic parameter, which plays an almost decisive role in the working performance of mixer blade and the whole mixer. The installation angle of the mixer truck interacts with other installation and operation parameters of the mixer. In the installation and use of the blades of the concrete mixer truck, in addition to the installation angle, it should also be comprehensively considered in combination with other installation and operation parameters of the concrete mixer truck.

目前市面上的搅拌车种类繁多，主要有以下几种类型：强制式搅拌机、单卧轴搅拌机、双卧轴搅拌机、自落式搅拌机等等。

At present, there are many kinds of mixer trucks on the market, mainly including the following types: forced mixer, single horizontal shaft mixer, double horizontal shaft mixer, self falling mixer, etc.

而混凝土搅拌车叶片也经过了一系列发展，由混凝土搅拌车刚开始问世时扇形叶片发展到当前的各种形状的叶片。搅拌机叶片的材质也由当时单一的钢铁发展为现今各式各样的钢铁和非钢铁材质。混凝土搅拌机叶片的形状各不相同，种类繁多。

The blades of concrete mixer truck have also undergone a series of development, from the fan-shaped blades when the concrete mixer truck first came out to the current blades of various shapes. The material of mixer blades also developed from a single steel at that time to a variety of steel and non steel materials today. The shape of concrete mixer blades is different and there are many kinds.

不同的搅拌车叶片形状在混凝土搅拌机搅拌过程中所产生的阻力是不同的，将会在一定程度上影响混凝土搅拌车的能耗，同时也会影响混凝土搅拌车的综合搅拌性能。同时在混凝土搅拌叶片选择过程中，也需要考虑到混凝土搅拌叶柄的形状和大小等因素，否则将会在搅拌机搅运行过程中造成搅拌机叶片与搅拌机叶柄不配套，导致混凝土搅拌机叶片在混凝土搅拌车的运行过程中的损坏率上升。

The resistance generated by different blade shapes of concrete mixer in the mixing process of concrete mixer is different, which will affect the energy consumption of concrete mixer to a certain extent, and also affect the comprehensive mixing performance of concrete mixer. At the same time, during the selection of concrete mixing blades, it is also necessary to take into account the shape and size of the concrete mixing blade handle, otherwise the mixer blades and the mixer blade handle will not match during the operation of the mixer, resulting in an increase in the damage rate of the concrete mixer blades during the operation of the concrete mixer.

此外，在混凝土搅拌车叶片的安装和使用过程中，需要综合考虑混凝土搅拌车叶片的数量与混凝土搅拌机在运转过程中的运行转速之间的关系，考虑混凝土搅拌车叶片的材质及耐磨程度。

In addition, during the installation and use of concrete mixer blades, it is necessary to comprehensively consider the relationship between the number of concrete mixer blades and the operating speed of concrete mixer during operation, as well as the material and wear resistance of concrete mixer blades.
