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.整个搅拌桶安装在支架上方，前部由两个支撑轮支撑。搅拌桶上设有检修孔，易于维护。

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.传动系统传动系统采用原始的车辆发动机取力方法，即通过底盘发动机取力。搅拌车通过万向联轴器将动力传递给可变柱塞液压泵，液压泵的高压油驱动定量柱塞。电动机和液压马达将动力传递给减速器并带动搅拌筒向前旋转或反向进行进料搅拌，搅拌和排出。减速器的输出法兰可在+ 6°的范围内偏转。混合鼓轴的位移得到补偿，以确保混合鼓的驱动不受汽车行驶过程中变形的影响。

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.液压系统液压系统主要由液压泵，液压马达，滤油器，油箱，高压油管，低压油管，回油管和过滤器组成。液压泵配有手动伺服调节手柄，可以调节液压油的流量和方向，从而控制混合鼓的转向和速度。混合滚筒的正向和反向旋转均可无级调节。

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.

混凝土自料搅拌车车在长期使用过程中不可避免地会降低性能。这要求我们在正常使用期间更加注意设备的维护和保养。只有这样，才能在保证设备良好性能的同时延长使用寿命。

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.
