自上料攪拌車使用過程中的大部分時間罐體都在轉動，操縱機構直接控制罐體的進料、攪拌、攪動、出料、停轉等工作狀態。下面來分析自上料攪拌車操縱機構設計吧。

Most of the time during the use of the feeding mixer, the tank body rotates. The operating mechanism directly controls the feeding, mixing, stirring, discharging, stopping and other working states of the tank body. Let's analyze the design of the control mechanism of the self feeding mixer.

一、操縱機構的形式

1、 Form of operating mechanism

1、操縱機構根據其連接方式，一般有三種形式:

1. There are generally three types of operating mechanism according to its connection mode:

（1）機械連桿方式

(1) Mechanical linkage mode

使用連桿連接到整車后端的兩個連動的操縱手柄，可以從車輛的兩面操作。此種連接方式可靠，結構比較復雜，易于維護。

It can be operated from both sides of the vehicle by using two interlocking operating handles connected to the rear end of the vehicle by connecting rods. This type of connection is reliable, complex in structure and easy to maintain.

（2）軟軸方式

(2) Flexible shaft mode

使用軟軸連接到整車后端的一個操縱手柄，僅能從車輛的單面操作。此種操縱機構相對簡單，比較美觀，但軟軸一旦損壞就無法修復。因此攪拌車使用這種操縱方式并不多見。

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

（3）電控方式

(3) Electric control mode

使用電動方式調節油泵轉向，線路元件損壞，非專業人員一般難以修復。攪拌車屬于工程車輛，運行工況較復雜，在國內很少使用。

When the oil pump steering is adjusted by electric means, the circuit components are damaged and it is difficult for non professional personnel to repair. Mixer truck belongs to engineering vehicle, and its operation condition is complex, so it is rarely used in China.

二、操縱機構需要實現的功能

2、 Functions to be realized by the control mechanism

1、駕駛室內可以控制罐體運轉

1. The operation of the tank can be controlled in the cab

駕駛室內的操縱手柄有兩個作用，一是防止在運行時罐體停轉或者反轉，二是方便進排料。注:筆者看到利勃海爾的攪拌車在駕駛室內不安裝操縱手柄，原因是擔心司機在卸料時無法看到后面的施工人員，可能會產生安全隱患。

The operating handle in the cab has two functions, one is to prevent the tank from stopping or reversing during operation, and the other is to facilitate feeding and discharging. Note: the author saw that Liebherr's mixer truck is not equipped with a control handle in the cab, because he is worried that the driver cannot see the construction personnel behind during unloading, which may cause potential safety hazards.

2、在整車后部設置操縱手柄，可對罐體進行控制。

2. The control handle is set at the rear of the vehicle to control the tank.

三、設計時應注意的問題

3、 Problems needing attention in design

目前攪拌車主要使用的機械連桿式操作機構。下面主要針對連桿式操縱機構的設計進行分析。

At present, the mechanical connecting rod type operating mechanism is mainly used in the mixer truck. The following mainly analyzes the design of the linkage type control mechanism.

1、操縱機構的功能性要求

1. Functional requirements of operating mechanism

操縱機構要求從駕駛內和整車后部均可以靈活操縱。操縱機構需要控制上裝的油泵和發動機的油門。操縱機構通過控制油泵的斜盤拉桿調節罐體的正反轉。由于油泵的斜盤拉桿的角度和作用力不同，這就要求對不同的油泵設計不同的放大機構。

The control mechanism is required to be flexible from the inside of the vehicle and the rear of the vehicle. The control mechanism needs to control the mounted oil pump and the throttle of the engine. The control mechanism adjusts the forward and reverse rotation of the tank body by controlling the swash plate pull rod of the oil pump. Since the angle and force of the swash plate pull rod of the oil pump are different, it is required to design different amplification mechanisms for different oil pumps.

2、操縱機構的可靠性要求

2. Reliability requirements for operating mechanism

攪拌車在運行過程中需要保證罐體的正向運轉，但攪拌車運行的工況一般較差，操縱手柄的振動容易導致油泵的斜盤拉桿復位，罐體可能會出現停轉或者反轉卸料現象。司機在行車時往往注意不到罐體的運轉情況，可設計駕駛室內的操縱手柄鎖緊機構來確保罐體的正常轉動。

During the operation of the mixer truck, it is necessary to ensure the normal operation of the tank. However, the operation condition of the mixer truck is generally poor. The vibration of the control handle easily causes the swash plate pull rod of the oil pump to reset, and the tank may stop or reverse discharge. The driver often fails to notice the operation of the tank when driving. The locking mechanism of the operating handle in the cab can be designed to ensure the normal rotation of the tank.

3、操縱機構的可維護性

3. Maintainability of control mechanism

操縱機構難免損壞，要方便維護，及時排除故障。

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

對攪拌車罐體的操作有多種方式，但原理基本相同。由于攪拌車工作環境比較惡劣，在實現功能性的同時，關鍵要提高操縱機構的可靠性和可維護性。更多相關內容就來我們網站http://www.www.boy7up.cn咨詢了解吧。

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