(1) Structure of concrete mixer

全自动自上料搅拌车是把水泥、砂石骨料和水混合并拌制成混凝土混合料的机械。主要由拌筒、加料和卸料机构、供水系统、原动机、传动机构、机架和支承装置等组成。目前，全自动自上料搅拌车被广泛应用于工业和民用工程中，在搅拌站设备中，全自动自上料搅拌车更是起着不可替代的作用。

Concrete mixer is a machine that mixes cement, aggregate and water to make concrete mixture. It is mainly composed of mixing drum, feeding and discharging mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. At present, the concrete mixer is widely used in industrial and civil engineering, in the mixing plant equipment, the concrete mixer plays an irreplaceable role.

（2）全自动自上料搅拌车的不同分类

(2) Different classification of concrete mixer

·按作业方式分：循环作业式全自动自上料搅拌车、连续作业式全自动自上料搅拌车

·According to the operation mode: cycle operation concrete mixer, continuous operation concrete mixer

循环作业式搅供料、搅拌、卸料三道工序是按一定时间间隔周期进行的，即按份拌制。拌制的各种物料都经过准确的称量，故搅拌质量好。目前大多采用此类型作业方式。

The three processes of mixing, feeding, mixing and discharging are carried out periodically according to a certain time interval, i.e. mixing by parts. All kinds of materials are accurately weighed, so the mixing quality is good. At present, this type of operation is mostly used.

连续作业式上述三道工序是在一个较长筒体内连续进行的，各料的配合比、搅拌时间难以控制，故搅拌质量差。目前使用较少。

Continuous operation the above three processes are carried out continuously in a long cylinder, and the mixing ratio and mixing time of each material are difficult to control, so the mixing quality is poor. At present, it is less used.

·按搅拌方式分：自落式全自动自上料搅拌车、强制式全自动自上料搅拌车

·According to mixing methods: self falling concrete mixer, forced concrete mixer

JZC500 )、JZC350、JZC250鹏飞建机的自落式搅拌机型号有：(自落式搅拌机，就是把混合料放在一个旋转的搅拌筒内，随着搅拌筒的旋转，筒内的叶片把混合料提升到一定的高度，然后靠自重自由撒落下来。周而复始，直至拌匀。常用于拌制塑性和半塑性混凝土。

JZC500), JZC350 and JZC250 are popular models of self falling mixers in Pengfei Construction Machinery Co., Ltd.: (self falling mixers put the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum lift the mixture to a certain height, and then scatter it freely by self weight. Repeat until well mixed. It is often used to mix plastic and semi-plastic concrete.

强制式搅拌机JDC500 、JDC350、JS4000、JS3000、JS2000、JS1500、JS1000、JS750、JS500鹏飞的强制式搅拌机型号有：（单卧轴强制式和双卧轴强制式，其工作时搅拌筒不动，而由筒内旋转轴上均置的叶片强制搅拌。这种搅拌机拌制质量好，生产效率高，但动力消耗大，且叶片磨损快。一般适用于拌制干硬性混凝土。）

Forced mixer jdc500, jdc350, JS4000, JS3000, JS2000, JS1500, JS1000, js750, JS500 Pengfei hot-selling forced mixer models are: (single horizontal shaft forced type and double horizontal shaft forced type, the mixing drum does not move when it works, but forced mixing by blades on the rotating shaft in the drum. This kind of mixer has good mixing quality, high production efficiency, high power consumption and fast blade wear. It is generally suitable for mixing dry and hard concrete.)

·按装置方式分：固定式搅拌机.移动式搅拌机

·According to the device mode: fixed mixer. Mobile mixer
