自动混凝土搅拌机使用过程中的大部分时间罐体都在转动，操纵机构直接控制罐体的进料、搅拌、搅动、出料、停转等工作状态。下面来分析自动混凝土搅拌机操纵机构设计吧。

The tank body rotates most of the time during the use of the automatic concrete mixer, and the operating mechanism directly controls the feeding, mixing, stirring, discharging, stopping and other working conditions of the tank body. Now let's analyze the control mechanism design of automatic concrete mixer.

一、操纵机构的形式

1、 Form of control mechanism

操纵机构根据其连接方式，一般有三种形式

The operating mechanism generally has three forms according to its connection mode

（1）机械连杆方式

(1) Mechanical linkage mode

使用连杆连接到整车后端的两个连动的操纵手柄，可以从车辆的两面操作。此种连接方式可靠，结构比较复杂，易于维护。

Two linked joysticks connected to the rear end of the vehicle can be operated from both sides of the vehicle. This connection mode is reliable, complex in structure and easy to maintain.

（2）软轴方式

(2) Flexible shaft mode

使用软轴连接到整车后端的一个操纵手柄，仅能从车辆的单面操作。此种操纵机构相对简单，比较美观，但软轴一旦损坏就无法修复。因此搅拌车使用这种操纵方式并不多见。

A joystick connected to the rear end of the vehicle with a flexible shaft can only be operated from one side of the vehicle. This kind of control mechanism is relatively simple and beautiful, but once the flexible shaft is damaged, it cannot be repaired. Therefore, it is rare to use this kind of operation mode for mixer trucks.

（3）电控方式

(3) Electric control mode

使用电动方式调节油泵转向，线路元件损坏，非专门的人员一般难以修复。搅拌车属于工程车辆，运行工况较复杂，在国内很少使用。

If the oil pump steering is adjusted electrically, the circuit components are damaged, and it is generally difficult for non specialized personnel to repair. Mixers are engineering vehicles with complex operating conditions, which are rarely used in China.

二、设计时应注意的问题

2、 Matters needing attention in design

目前搅拌车主要使用的机械连杆式操作机构。下面主要针对连杆式操纵机构的设计进行分析。

At present, the mechanical linkage type operating mechanism is mainly used for mixer trucks. The following mainly analyzes the design of the linkage control mechanism.

操纵机构的功能性要求

Functional requirements of control mechanism

操纵机构要求从驾驶内和整车后部均可以灵活操纵。操纵机构需要控制上装的油泵和发动机的油门。操纵机构通过控制油泵的斜盘拉杆调节罐体的正反转。由于油泵的斜盘拉杆的角度和作用力不同，这就要求对不同的油泵设计不同的放大机构。

The control mechanism is required to be flexible from the inside of the driver and the rear of the vehicle. The operating mechanism needs to control the upper mounted oil pump and the accelerator of the engine. The operating mechanism regulates the forward and reverse rotation of the tank body by controlling the swashplate pull rod of the oil pump. Because the angle and force of the swashplate pull rod of the oil pump are different, different magnifying mechanisms are required for different oil pumps.

操纵机构的可靠性要求

Reliability requirements for operating mechanism

搅拌车在运行过程中需要保证罐体的正向运转，但搅拌车运行的工况一般较差，操纵手柄的振动容易导致油泵的斜盘拉杆复位，罐体可能会出现停转或者反转卸料现象。司机在行车时往往注意不到罐体的运转情况，可设计驾驶室内的操纵手柄锁紧机构来确保罐体的正常转动。

During the operation of the mixer, it is necessary to ensure the tank body to run in the positive direction, but the working condition of the mixer is generally poor. The vibration of the operating handle is easy to cause the reset of the swashplate pull rod of the oil pump, and the tank body may stop or reverse unloading. When driving, the driver often cannot notice the operation of the tank, so the locking mechanism of the joystick in the cab can be designed to ensure the normal rotation of the tank.

操纵机构的可维护性

Maintainability of control mechanism

操纵机构难免损坏，要方便维护，及时排除故障。

The operating mechanism is inevitably damaged, which shall be convenient for maintenance and timely troubleshooting.

对搅拌车罐体的操作有多种方式，但原理基本相同。由于搅拌车工作环境比较恶劣，在实现功能性的同时，关键要提高操纵机构的可靠性和可维护性。更多相关内容就来我们网站http://www.zkhntjbc.com咨询了解吧。

There are many ways to operate the tank of the mixer truck, but the principle is basically the same. Due to the harsh working environment of the mixer, it is critical to improve the reliability and maintainability of the operating mechanism while realizing the functionality.
