搅拌一体车在工程建筑中使用的很多，搅拌车上的零配件有很多，在它们的共同作用下搅拌车才能正常的工作，来看一下搅拌车的主要零配件的性能。搅拌筒是搅拌车上主要的部分之一，搅拌筒的作用是非常重要的，它跟搅拌车的使用寿命是息息相关的，搅拌筒主要是由筒体、密封管、叶片等部分组成，漏斗状的密封管能够确保顺利进料，曲面状的叶片有助于地塌落度混凝土的出料性能，在叶片上有孔眼，能减少混凝土在其上的粘附，有利于提高预拌混凝土的质量。整个搅拌筒体是安装在支架上方的，前部有两个托轮支撑，搅拌筒体上设有人孔，便于维修。

Mixer truck is widely used in engineering construction. There are many spare parts on the mixer truck. Under their joint action, the mixer truck can work normally. Let's take a look at the performance of the main spare parts of the mixer truck. The mixing drum is one of the main parts of the mixer truck. The role of the mixing drum is very important. It is closely related to the service life of the mixer truck. The mixing drum is mainly composed of the drum, sealing pipe, blade and other parts. The funnel-shaped sealing pipe can ensure the smooth feeding, and the curved blade is conducive to the discharging performance of the ground slump concrete. There are holes on the blade, which can reduce the pressure Reducing the adhesion of concrete on it is helpful to improve the quality of ready mixed concrete. The whole mixing cylinder is installed above the support, with two supporting wheels at the front. The mixing cylinder is provided with a manhole for easy maintenance.

传动系统采用的是原车发动机取力形式，由取力器从发动机上取力传送到减速机上并驱动搅拌罐做正反旋转，从而实现进料出料。液压系统主要是由液压泵、液压马达、减速机等组成，液压泵上设有手动伺服调节手柄，可以调节液压油的流量及流向，从而控制搅拌罐的转向和转速，搅拌罐的正反转均能无级调速。

The transmission system adopts the power take-off form of the original vehicle engine. The power take-off device takes the power from the engine and transmits it to the reducer, and drives the mixing tank to rotate forward and backward, so as to realize the feeding and discharging. The hydraulic system is mainly composed of hydraulic pump, hydraulic motor, reducer, etc. the hydraulic pump is equipped with a manual servo control handle, which can adjust the flow and flow direction of hydraulic oil, so as to control the rotation and speed of the mixing tank. The forward and reverse rotation of the mixing tank can be stepless speed regulation.
            

搅拌一体车的轴承，轴承在正常的使用过程中是慢慢磨损的，但是如果因发动机的装配调整不当、润滑油的品质不好或使用条件恶劣等因素致使轴承过早的磨损或者出现各种损伤，则是人为造成的过早损坏，轴承过早损坏的形式有机械损坏、轴承穴蚀、疲劳点蚀、腐蚀等等。机械损伤是指轴瓦的合金表面出现不同程度的沟痕，严重时在接触面发生金属剥离以及出现大面积的杂乱划伤，一般情况下接触面损伤与烧油现象同时存在。轴承穴蚀是轴承在气缸压力冲击载荷的反复作用下，表面层发生塑性变形和冷作硬化，局部丧失变形能力，逐步形成条纹并不断扩展，然后随着磨屑的脱落，在受载表面形成凹穴。如果定位不良，需拆下换挡叉轴，检验定位球及弹簧。如果齿轮未完全啮合，用手推动掉档的齿轮或齿套，能者却啮合，应检查换挡叉是否弯曲或者磨损，换挡叉固定螺丝有没有松动，叉端与齿轮槽间隙是否过大。若是换挡良好，而齿轮或齿套又能完全啮合时，应检查齿轮是否磨成雏形、轴承是否松旷、变速轴是否前后移动。根据上述检查所发现的问题，按标准修复，必要时需更换新件。

The bearing of the mixer truck is slowly worn in the normal use process, but if the premature wear or various damages of the bearing are caused by improper assembly and adjustment of the engine, poor quality of lubricating oil or bad use conditions, it is the premature damage caused by human. The forms of premature damage of the bearing include mechanical damage, bearing cavitation, fatigue pitting, fatigue pitting, etc Corrosion and so on. Mechanical damage refers to the groove marks on the alloy surface of bearing bush in different degrees. In severe cases, metal peeling occurs on the contact surface and a large area of messy scratch occurs. Generally, the contact surface damage and oil burning exist at the same time. The cavitation erosion of bearing is that the plastic deformation and cold work hardening occur on the surface layer of bearing under the repeated action of cylinder pressure impact load, and the local deformation ability is lost, gradually forming stripes and expanding, and then with the falling off of wear debris, the cavitation is formed on the loaded surface. If the positioning is not good, remove the shift fork shaft and inspect the setting ball and spring. If the gear is not fully meshed and the gear or gear sleeve is pushed by hand, but the gear or gear sleeve can be meshed, check whether the shift fork is bent or worn, whether the fixed screw of the shift fork is loose, and whether the clearance between the fork end and the gear groove is too large. If the gear shift is good and the gear or gear sleeve can be fully meshed, check whether the gear is ground into a rudiment, whether the bearing is loose, and whether the variable speed shaft moves forward and backward. According to the problems found in the above inspection, repair according to the standard, and replace with new parts if necessary.

搅拌一体车搅拌操作杆分布在车辆尾部两侧，它可以控制搅拌车的进料和出料。

The mixing operating rods of the mixer truck are distributed on both sides of the rear of the truck, which can control the feeding and discharging of the mixer truck.
