1、上下料时间不合理：自动上料搅拌车因料仓内无法加装料位机，所以基本都有时间控制。如何设置时间参数，上下料时间设置还是比较简单的，在初次使用时，先设置一个比较短的时间，然后根据每次吸料位置慢慢加，当达到料位达到吸料口的时间，再减去一秒就是合理时间。放料时间是确保放完料再加一秒。这样做的目的有两个好处：一是料位太高对滤芯伤害特别大；二是每次料都能放干净。
1. Unreasonable loading and unloading time: automatic feeding mixer can't install level machine in the silo, so it basically has time control. How to set the time parameter? The setting of loading and unloading time is relatively simple. In the first use, first set a relatively short time, and then add it slowly according to each suction position. When the material level reaches the suction port, then subtract one second is the reasonable time. The discharging time is one second after discharging. There are two advantages in this way: one is that the material level is too high, which will cause great damage to the filter element; Second, the material can be put clean every time.
2、自动上料搅拌车进料口给料量是否合理：正确的方式是物料在吸料口和空气形成一定的气物混合比，在气流推动下均匀流入上料机。这个时候我们需要将料仓设计带有补气功能。如果物料积压时间过长可能会很硬，这个时候需要在料仓上装一个振荡器，敲碎结块的物料。
2. Whether the feeding rate of the automatic feeding mixer is reasonable: the correct way is that the material forms a certain gas-solid mixture ratio at the suction port and the air, and flows into the feeder evenly under the push of the air flow. At this time, we need to design the silo with air supply function. If the material overstocking time is too long, it may be very hard. At this time, we need to install an oscillator on the silo to break the caked material.
除上述问题之外，还应该做到以下注意事项：
In addition to the above problems, we should also pay attention to the following:
1、冬期施工时，一定要做到：开机前检查是否出现结冰情况；下班时认真排除拌筒内及供水系统内残存积水，关闭水泵的开关，将控制手柄置于“停止"位置。
1. Winter construction, we must do: check whether there is ice before starting up; After work, carefully remove the residual water in the mixing drum and water supply system, turn off the switch of the water pump, and put the control handle in the "stop" position.
2、混凝土搅拌车在卸料的时候，如果发现水分蒸发，塌落度偏低不能满足用户需求时，可适当向筒内加水，然后以10-14r/min的速度旋转30转后再卸料，使混凝士充分搅拌。
2. When the concrete mixer truck is discharging, if it is found that the water is evaporated and the slump is too low to meet the needs of users, it can add water to the cylinder properly, and then rotate it for 30 turns at the speed of 10-14r / min before discharging, so that the concrete can be fully mixed.
3、混凝土搅拌车在空载运行的过程中，搅拌筒不得停转以免颤动时造成滚道和托轮局部磕碰，导致滚道和托轮的不正常损坏。
3. In the process of no-load operation of concrete mixer, the mixing drum shall not stop, so as to avoid the local collision between the raceway and supporting wheel when it vibrates, resulting in the abnormal damage of raceway and supporting wheel.
4、水箱的水量要经常加满，作为备用。水箱加水前，必须打开放气阀把箱内空气放掉；冲洗时打开气阀，冲洗完毕或者停用的时候应将水罐内气体放掉。冬季停放的时候，水箱和供水系统里，不应该有多余的水，防止冻裂，水箱仅在供水时加压自动，混凝土自动上料搅拌车安全使用方法不要带着加压水箱在公路上行驶。
4. The water tank should be filled up frequently for standby. Before adding water to the water tank, the vent valve must be opened to let off the air in the tank; Open the air valve when flushing, and discharge the gas in the water tank after flushing or when it is stopped. When parking in winter, there should be no extra water in the water tank and water supply system to prevent frost cracking. The water tank is only pressurized automatically when supplying water, and the concrete automatic feeding mixer is safe to use. Do not drive on the road with the pressurized water tank.
