1、 Power take-off device

自上料攪拌車采用發(fā)動機(jī)取力方式，取力裝置的作用是通過操縱取力開關(guān)將發(fā)動機(jī)動力取出，經(jīng)液壓系統(tǒng)驅(qū)動攪拌筒，攪抖筒在進(jìn)料和運(yùn)輸過程中正向旋轉(zhuǎn)，以利于進(jìn)料和對混

The self loading mixer adopts the engine power take-off mode. The function of the power take-off device is to take out the engine power by operating the power take-off switch, drive the mixing drum through the hydraulic system, and the mixing drum rotates positively during feeding and transportation, so as to facilitate feeding and mixing

凝土進(jìn)行攪拌，在出料時反向旋轉(zhuǎn)，在工作終結(jié)后切斷與發(fā)動機(jī)的動力聯(lián)接。

The concrete shall be stirred and rotated reversely during discharging, and the power connection with the engine shall be cut off after the work is completed.

二、液壓系統(tǒng)

2、 Hydraulic system

將經(jīng)取力器取出的發(fā)動機(jī)動力，轉(zhuǎn)化為液壓能(排量和壓力)，再經(jīng)馬達(dá)輸出為機(jī)械能(轉(zhuǎn)速和扭矩)，為攪拌筒轉(zhuǎn)動提供動力。

The engine power taken out by the power takeoff is converted into hydraulic energy (displacement and pressure), and then output into mechanical energy (speed and torque) by the motor to provide power for the rotation of the mixing drum.

三、減速機(jī)

3、 Reducer

將液壓系統(tǒng)中馬達(dá)輸出的轉(zhuǎn)速減速后，傳給攪拌筒。

The speed output by the motor in the hydraulic system is decelerated and transmitted to the mixing drum.

四、操縱機(jī)構(gòu)

4、 Operating mechanism

控制自上料攪拌車攪拌筒旋轉(zhuǎn)方向，使之在進(jìn)料和運(yùn)輸過程中正向旋轉(zhuǎn)，出料時反向旋轉(zhuǎn)?？刂茢嚢柰驳霓D(zhuǎn)速。

Control the rotation direction of the mixing drum from the loading mixer to make it rotate forward during feeding and transportation and reverse during discharging. Control the rotating speed of the mixing drum.

五、攪拌裝置

5、 Mixing device

自上料攪拌車主要由攪拌筒及其輔助支撐部件組成。攪拌筒是混凝土的裝載容器，它是由優(yōu)質(zhì)耐磨薄鋼板制成，為了能夠自動裝、卸混凝土，其內(nèi)壁焊有特殊形狀的螺旋葉片。轉(zhuǎn)動時混凝土沿葉片的螺旋方向運(yùn)動，在不斷的提升和翻動過程中受到混合和攪拌。在進(jìn)料及運(yùn)輸過程中，攪拌筒正轉(zhuǎn)，混凝土沿葉片向里運(yùn)動，出料時，攪拌筒反轉(zhuǎn)，混凝土沿著葉片向外卸出。

The self loading mixer is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a concrete loading container, which is made of high-quality wear-resistant steel plate. In order to automatically load and unload concrete, its inner wall is welded with spiral blades of special shape. When rotating, the concrete moves along the spiral direction of the blade and is mixed and stirred in the process of continuous lifting and turning. During feeding and transportation, the mixing drum rotates forward, and the concrete moves inward along the blade. When discharging, the mixing drum reverses, and the concrete is discharged outward along the blade.

攪拌筒的轉(zhuǎn)動則是靠液壓驅(qū)動裝置來保證。裝載量為3～6立方的自上料攪拌車一般采用由汽車發(fā)動機(jī)通過動力輸出軸帶動液壓泵，再由高壓油推動液壓馬達(dá)驅(qū)動攪拌筒，裝載量為9～12立方的則由車載輔助柴油機(jī)帶動液壓泵驅(qū)動液壓馬達(dá)。

The rotation of the mixing drum is guaranteed by the hydraulic driving device. The self loading mixer with a loading capacity of 3 ~ 6 cubic meters generally uses the hydraulic pump driven by the automobile engine through the power output shaft, and then the hydraulic motor driven by the high-pressure oil to drive the mixing drum. For the mixer with a loading capacity of 9 ~ 12 cubic meters, the hydraulic pump driven by the on-board auxiliary diesel engine drives the hydraulic motor.

葉片是攪拌裝置中的主要部件，損壞或嚴(yán)重磨損會導(dǎo)致混凝土攪拌不均勻。另外，葉片的角度如設(shè)計(jì)不合理，還會使混凝土出現(xiàn)離析。

Blade is the main component of mixing device. Damage or serious wear will lead to uneven mixing of concrete. In addition, if the design of blade angle is unreasonable, the concrete will be separated.
