The mixing drum that causes the mixer truck not to rotate usually has the following two conditions: (1) hydraulic system or engine failure; (2) motor failure. The treatment method is as follows.

一，液压系统或发动机故障的处理：

1、 Troubleshooting of hydraulic system or engine:

（1）打开搅拌一体车混合管检查孔盖，松开电机上高压软管的管接头，旋转搅拌筒，使搅拌筒的混合孔向下倾斜，排出混凝土搅拌筒的混合孔;

(1) Open the inspection hole cover of the mixing pipe of the mixer truck, loosen the pipe joint of the high-pressure hose on the motor, rotate the mixing drum, make the mixing hole of the mixing drum tilt downward, and discharge the mixing hole of the concrete mixing drum;

（2）从电机上拆下故障车辆的高压软管，连接高压软管进行救援，将另一端连接到救援车的油泵，并将应急回油管的末端连接到故障车辆的电动机。回油管的另一端连接到救援车的油泵返回口，救援车用于控制故障车混合滚筒的旋转。

(2) Remove the high-pressure hose from the motor, connect the high-pressure hose for rescue, connect the other end to the oil pump of the rescue vehicle, and connect the end of the emergency oil return pipe to the motor of the fault vehicle. The other end of the oil return pipe is connected to the oil pump return port of the rescue vehicle, which is used to control the rotation of the mixing drum of the fault vehicle.

我们的现场测试发现，对于生产工厂中的所有工具，使用第二种方法大约需要1小时。如果施工现场的时间可能更长，建议使用种方法排出坩埚。

Our field tests found that it took about an hour to use the second method for all the tools in the production plant. If the construction site time may be longer, it is recommended to use the first method to discharge the crucible.

二，电机故障：操作相对简单，救援车的电机可以拆除故障车，然后将各种油管连接起来，启动救援车可以将混合鼓内的痰液排出。

2、 Motor failure: the operation is relatively simple, the motor of the rescue vehicle can be removed, and then all kinds of oil pipes can be connected, and the sputum in the mixing drum can be discharged by starting the rescue vehicle.

简而言之，对于搅拌一体车，当发生故障时，应及时判断故障原因，并在故障之前采取有效措施排出自动上料搅拌车中的缺陷。

In short, for the mixer truck, when the fault occurs, we should judge the cause of the fault in time, and take effective measures to eliminate the defects in the automatic feeding mixer truck before solving the fault.

，合理确定保护期：搅拌一体车保护周期是指汽车保护的距离或时间。在实际应用过程中，车主应参考汽车制造商介绍的保护周期，联系车辆自身的技术和应用前提，并对保护周期进行适当调整。

First of all, reasonably determine the protection period: the protection period of mixer truck refers to the distance or time of vehicle protection. In the process of practical application, the vehicle owner should refer to the protection cycle introduced by the automobile manufacturer, contact the vehicle's own technology and application premise, and adjust the protection cycle appropriately.

二，测试的应用：搅拌一体车制造商的自由检测运动往往有利于车主的长度，车主可以应用这些测试活动进行特定的体检，识别并一些潜力实时出现问题，节约需求可能会在未来带来高昂的维护和保护成本。

2、 Comprehensive application of free testing: the free testing movement of all-in-one mixer manufacturers is often conducive to the length of vehicle owners. Vehicle owners can use these testing activities to conduct specific physical examination, identify and eliminate some potential real-time problems, and save demand, which may bring high maintenance and protection costs in the future.

三，修复尽可能坍塌的部件：许多自动上料搅拌车的拥有者都有这种感觉，就像坍塌后汽车部件的维护不可阻挡一样，因此车辆过早进入维修期。这种情况的原因是要了解修理工的装配技巧和质量。

3、 Repair the collapsed parts as much as possible: many owners of automatic feeding mixer have this feeling, just like the unstoppable maintenance of automobile parts after collapse, so the vehicle enters the maintenance period too early. The reason for this situation is to understand the assembly skills and quality of the repairman first.

因此，它是一种防碰撞修复部件，它使用各种的技能保护设备和技术来保护汽车免于拆卸，防止损坏汽车部件和部件，提高保护质量，从而降低总维护成本。

Therefore, it is an anti-collision repair parts, it uses a variety of advanced skills to protect equipment and technology to protect the car from disassembly, prevent damage to car parts and components, improve the quality of protection, thereby reducing the total maintenance cost.
