Mixing bucket is the main component of concrete mixer truck, which is mainly composed of cylinder, sealing pipe, blade and mixing blade. The funnel-shaped sealing pipe ensures smooth feeding, and the curved blade helps to reduce the discharge performance of low slump concrete. There are holes in the blade to reduce the adhesion of concrete on it, which is beneficial to improve the ready mixed concrete.

1.整個攪拌桶安裝在支架上方，前部由兩個支撐輪支撐。攪拌桶上設有檢修孔，易于維護。

1. The whole mixing drum is installed above the support, and the front part is supported by two supporting wheels. The mixing drum is provided with an access hole for easy maintenance.

2.傳動系統傳動系統采用原始的車輛發動機取力方法，即通過底盤發動機取力。攪拌車通過萬向聯軸器將動力傳遞給可變柱塞液壓泵，液壓泵的高壓油驅動定量柱塞。電動機和液壓馬達將動力傳遞給減速器并帶動攪拌筒向前旋轉或反向進行進料攪拌，攪拌和排出。減速器的輸出法蘭可在+ 6°的范圍內偏轉。混合鼓軸的位移得到補償，以確保混合鼓的驅動不受汽車行駛過程中變形的影響。

2. The transmission system adopts the original vehicle engine power take-off method, that is, through the chassis engine. The mixer transfers power to the variable plunger hydraulic pump through universal coupling, and the high-pressure oil of the hydraulic pump drives the quantitative plunger. The electric motor and hydraulic motor transmit the power to the reducer and drive the mixing drum to rotate forward or backward for feeding, mixing and discharging. The output flange of the reducer can be deflected in the range of + 6 °. The displacement of the mixing drum shaft is compensated to ensure that the driving of the mixing drum is not affected by the deformation of the vehicle during driving.

3.液壓系統液壓系統主要由液壓泵，液壓馬達，濾油器，油箱，高壓油管，低壓油管，回油管和過濾器組成。液壓泵配有手動伺服調節手柄，可以調節液壓油的流量和方向，從而控制混合鼓的轉向和速度。混合滾筒的正向和反向旋轉均可無級調節。

3. Hydraulic system the hydraulic system is mainly composed of hydraulic pump, hydraulic motor, oil filter, oil tank, high pressure oil pipe, low pressure oil pipe, oil return pipe and filter. The hydraulic pump is equipped with manual servo adjusting handle, which can adjust the flow and direction of hydraulic oil, so as to control the steering and speed of mixing drum. The forward and reverse rotation of the mixing drum can be adjusted steplessly.

混凝土自料攪拌車車在長期使用過程中不可避免地會降低性能。這要求我們在正常使用期間更加注意設備的維護和保養。只有這樣，才能在保證設備良好性能的同時延長使用壽命。

The performance of concrete mixer truck will inevitably decrease in the long-term use. This requires us to pay more attention to the maintenance of the equipment during normal use. Only in this way can the good performance of the equipment be guaranteed and the service life can be prolonged.
