1、上下料時間不合理：自動上料攪拌車因料倉內無法加裝料位機，所以基本都有時間控制。如何設置時間參數，上下料時間設置還是比較簡單的，在初次使用時，先設置一個比較短的時間，然后根據每次吸料位置慢慢加，當達到料位達到吸料口的時間，再減去一秒就是合理時間。放料時間是確保放完料再加一秒。這樣做的目的有兩個好處：一是料位太高對濾芯傷害特別大；二是每次料都能放干凈。
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、自動上料攪拌車進料口給料量是否合理：正確的方式是物料在吸料口和空氣形成一定的氣物混合比，在氣流推動下均勻流入上料機。這個時候我們需要將料倉設計帶有補氣功能。如果物料積壓時間過長可能會很硬，這個時候需要在料倉上裝一個振蕩器，敲碎結塊的物料。
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.
除上述問題之外，還應該做到以下注意事項：
In addition to the above problems, we should also pay attention to the following:
1、冬期施工時，一定要做到：開機前檢查是否出現結冰情況；下班時認真排除拌筒內及供水系統內殘存積水，關閉水泵的開關，將控制手柄置于“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、混凝土攪拌車在卸料的時候，如果發現水分蒸發，塌落度偏低不能滿足用戶需求時，可適當向筒內加水，然后以10-14r/min的速度旋轉30轉后再卸料，使混凝士充分攪拌。
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、混凝土攪拌車在空載運行的過程中，攪拌筒不得停轉以免顫動時造成滾道和托輪局部磕碰，導致滾道和托輪的不正常損壞。
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、水箱的水量要經常加滿，作為備用。水箱加水前，必須打開放氣閥把箱內空氣放掉；沖洗時打開氣閥，沖洗完畢或者停用的時候應將水罐內氣體放掉。冬季停放的時候，水箱和供水系統里，不應該有多余的水，防止凍裂，水箱僅在供水時加壓自動，混凝土自動上料攪拌車使用方法不要帶著加壓水箱在公路上行駛。
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.
