Mixing drum is the main part of small self loading mixer truck, which is mainly composed of cylinder, sealing tube, blade and mixing blade. Funnel shaped airtight tube ensures smooth supply. Curved blades help to reduce the drainage performance of low slump concrete. There are holes in the blades to reduce the adhesion of the concrete, which helps to improve the ready mixed concrete. Quality.

1.整个搅拌缸都安装在支架上，前部由两个支撑轮支撑，搅拌缸有一个检修孔，易于维护。

1. The whole mixing cylinder is installed on the bracket, the front part is supported by two supporting wheels, and the mixing cylinder has an access hole, which is easy to maintain.

2.传动系统传动系统使用独特的车辆发动机动力输出系统。即，它从底盘引擎汲取动力。搅拌车通过万向联轴器将动力传递到可变柱塞液压泵。液压泵的高压油驱动计量柱塞。马达和液压马达将功率传递到减速器，并来回旋转混合滚筒以搅拌，搅拌和排出饲料。

2. Transmission system the transmission system uses a unique vehicle engine power take-off system. That is, it draws power from the chassis engine. The power is transferred to the variable plunger hydraulic pump by universal coupling. The high pressure oil of the hydraulic pump drives the metering plunger. The motor and hydraulic motor transmit power to the reducer and rotate the mixing drum back and forth to stir, stir and discharge the feed.

减速器的输出法兰补偿混合鼓轴的位移，从而使混合鼓的运行不受车辆行驶时变形或变形的影响。

The output flange of the reducer compensates the displacement of the mixing drum shaft, so that the operation of the mixing drum is not affected by the deformation of the vehicle.

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，该手柄可以调节液压油的流量和方向，以控制搅拌桶的转向和速度。混合滚筒的正向和反向旋转均可无级调节。

3. Hydraulic system 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 a manual servo control handle, which can adjust the flow and direction of hydraulic oil to control the steering and speed of the mixing drum. The forward and reverse rotation of the mixing drum can be adjusted steplessly.

由于小型自上料搅拌车的性能在长期使用后不可避免地会降低，因此在正常使用期间必须注意设备的维护和保养。只有这样，才能在确保设备良好性能的前提下延长使用寿命。

As the performance of small self loading mixer will inevitably decrease after long-term use, it is necessary to pay attention to the maintenance of the equipment during normal use. Only in this way can the service life of the equipment be extended on the premise of ensuring good performance of the equipment.
