What control system equipment does the concrete mixer have

　　混凝土搅拌车系统阐明及运用：搅拌车搅拌筒：该车型所采用的搅拌筒方式是一种应用较为普遍的构造方式，搅拌筒采用梨形构造，其清洗用水和运输过程中视需求补充参加的拌合水，均由搅拌筒头部进料口处注入筒内。

　　Description and application of concrete mixer system: mixer truck mixing drum: the mixing drum adopted by this model is a kind of widely used structure. The mixing drum adopts pear shaped structure, and its cleaning water and mixing water added in the transportation process according to the demand are injected into the cylinder from the inlet of the mixing drum head.

　　传动系统：该搅拌筒的驱动方式为以发起机为动力源，由发起机后端的取力器取力，经过传动轴传送到变量柱塞液压泵，经定量柱塞油马达，再经过减速机带动搅拌筒转动。搅拌筒的进出料系统（装料和卸料机构）：是辅助搅拌筒工作的重要安装。

　　Transmission system: the driving mode of the mixing drum is the starter as the power source. The power take-off at the back end of the starter is used to take the power. The power is transmitted to the variable displacement piston hydraulic pump through the transmission shaft, and then the mixing drum is driven to rotate by the reducer through the quantitative plunger oil motor. The feeding and discharging system of mixing drum (loading and discharging mechanism): it is an important installation to assist the mixing drum.

　　搅拌车支配系统：是整个搅拌车的控制部件，支配面板上开有“工字形”槽，是支配杆的活动空间；并且后半部的槽上开有限位孔，用来固定支配杆的位置。该支配系统经过汽车尾部的左右两个支配杆来控制搅拌筒的正、反转和转速，从而来完成进出料以及搅拌动作。

　　Mixer control system: it is the control part of the whole mixer. There is an I-shaped groove on the control panel, which is the movable space of the control rod; and the slot in the rear half is provided with a finite position hole to fix the position of the control rod. The control system controls the forward, reverse and rotation speed of the mixing drum through the left and right control rods at the rear of the car, so as to complete the feeding and mixing actions.

　　供水系统：混凝土搅拌车的供水系统主要用来清洗搅拌安装。该车型的供水系统共有两种型式，一种是离心水泵供水系统；一种是压力水箱供水系统，可供用户选装。

　　Water supply system: the water supply system of concrete mixer is mainly used for cleaning and mixing installation. There are two types of water supply system for this vehicle, one is centrifugal pump water supply system, the other is pressure water tank water supply system, which can be selected by users.
             

　　混凝土搅拌车使用注意事项：

　　Precautions for use of concrete mixer truck:

　　1、液压系统压力应符合使用说明书中的规定，不得随意调整。液压油的油质和油量应符合原定要求。

　　1. The pressure of the hydraulic system should be in accordance with the provisions of the operation manual, and should not be adjusted at will. The quality and quantity of hydraulic oil should meet the original requirements.

　　2、混凝土搅拌车装料前，应先排净拌筒内残存的积水和杂物。在运输过程中要不停的转动，以防混凝土离析。混凝土搅拌运输车到达工地和卸料之前，应先使拌筒全速以14—18转/分转动1—2分钟，然后再进行反转卸料。反转之前，应使搅拌筒停稳不转。

　　2. Before the concrete mixer truck is loaded, the residual water and sundries in the mixing drum shall be drained. In the process of transportation, keep rotating to prevent concrete segregation. Before the concrete mixer truck arrives at the construction site and unloads, the mixing drum shall be rotated at full speed at 14-18 rpm for 1-2 minutes, and then reverse unloading shall be carried out. Before reversing, the mixing drum should be stopped stably.

　　3、环境温度高于+25摄氏度，从装料、运输、到卸料延续时间不得超过60分钟，环境温度低于+25摄氏度，上述时间不得超过90分钟。

　　3. If the ambient temperature is higher than + 25 ℃, the duration from loading, transportation to unloading shall not exceed 60 minutes; if the ambient temperature is lower than + 25 ℃, the above time shall not exceed 90 minutes.

　　4、冬期施工时，应切实做到：开机前检查是否结冰；下班时认真排除拌筒内及供水系统内残存积水，关闭水泵开关，将控制手柄置于“停止”位置。

　　4. During winter construction, it is necessary to check whether there is icing before starting the machine; when off duty, carefully remove the residual water in the mixing drum and water supply system, turn off the water pump switch, and put the control handle at the "stop" position.

　　5、在施工现场卸料完毕后，应立即用搅拌车随带的软管冲洗进料斗、出料斗、卸料溜槽等处，粘附在车身各处的污泥及混凝土。在返回搅拌站的途中，应向搅拌筒内注150---200L水以清洗筒壁及叶片粘结的混凝土残渣。

　　5. After unloading at the construction site, the inlet hopper, discharge hopper and discharge chute should be flushed with the hose attached to the mixer to remove the sludge and concrete adhering to the vehicle body. On the way back to the mixing station, 150-200l water should be injected into the mixing drum to clean the concrete residue bonded by the cylinder wall and blades.
