1、 Power take-off device

自上料攪拌機(jī)采用發(fā)動(dòng)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(dòng)機(jī)動(dòng)力取出，經(jīng)液壓系統(tǒng)驅(qū)動(dòng)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)料和對混凝土進(jìn)行攪拌，在出料時(shí)反向旋轉(zhuǎn)，在工作終結(jié)后切斷與發(fā)動(dòng)機(jī)的動(dòng)力聯(lián)接。

The self loading mixer adopts the engine power take-off mode. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch, and drive the mixing drum through the hydraulic system. The mixing drum rotates in a positive direction during the process of feeding and transportation, so as to facilitate the feeding and mixing of concrete. The power take-off device rotates in a reverse direction when discharging, and cuts off the power connection with the engine after the end of the work.

二、液壓系統(tǒng)

2、 Hydraulic system

將經(jīng)取力器取出的發(fā)動(dòng)機(jī)動(dòng)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(dòng)提供動(dòng)力。

The engine power taken out by the power take-off 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 of the motor output in the hydraulic system is decelerated and transmitted to the mixing drum.
                      

四、操縱機(jī)構(gòu)

4、 Operating mechanism

控制自上料攪拌機(jī)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(shí)反向旋轉(zhuǎn)?？刂茢嚢柰驳霓D(zhuǎn)速。

Control the rotation direction of the mixing drum of the self feeding mixer to make it rotate forward in the process of feeding and transportation and reverse in the process of discharging. Control the rotation speed of the mixing drum.

五、攪拌裝置

5、 Mixing device

自上料攪拌機(jī)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)良耐磨薄鋼板制成，為了能夠自動(dòng)裝、卸混凝土，其內(nèi)壁焊有特殊形狀的螺旋葉片。

The self loading mixer is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a loading container for concrete. It is made of fine wear-resistant steel sheet. In order to load and unload concrete automatically, the inner wall of the mixing drum is welded with spiral blades of special shape.

轉(zhuǎn)動(dòng)時(shí)混凝土沿葉片的螺旋方向運(yùn)動(dòng)，在不斷的提升和翻動(dòng)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(dòng)，出料時(shí)，攪拌筒反轉(zhuǎn)，混凝土沿著葉片向外卸出。

When it rotates, the concrete moves along the spiral direction of the blade, and is mixed and stirred in the process of continuous lifting and turning. In the process of feeding and transportation, the mixing drum rotates forward and the concrete moves inward along the blades. When discharging, the mixing drum reverses and the concrete is discharged outward along the blades.

攪拌筒的轉(zhuǎn)動(dòng)則是靠液壓驅(qū)動(dòng)裝置來保證。裝載量為3～6立方的自上料攪拌機(jī)一般采用由汽車發(fā)動(dòng)機(jī)通過動(dòng)力輸出軸帶動(dòng)液壓泵，再由高壓油推動(dòng)液壓馬達(dá)驅(qū)動(dòng)攪拌筒，裝載量為9～12立方的則由車載輔助柴油機(jī)帶動(dòng)液壓泵驅(qū)動(dòng)液壓馬達(dá)。葉片是攪拌裝置中的主要部件，損壞或嚴(yán)重磨損會(huì)導(dǎo)致混凝土攪拌不均勻。另外，葉片的角度如果設(shè)計(jì)不合理，還會(huì)使混凝土出現(xiàn)離析。

The rotation of the mixing drum is ensured by the hydraulic driving device. For the self loading mixer with a loading capacity of 3-6 cubic meters, the vehicle engine drives the hydraulic pump through the power output shaft, and then the high-pressure oil drives the hydraulic motor to drive the mixing drum. For the mixer with a loading capacity of 9-12 cubic meters, the vehicle auxiliary diesel engine drives the hydraulic pump to drive the hydraulic motor. The blade is the main component of the mixing device, and damage or serious wear will lead to uneven mixing of concrete. In addition, if the blade angle is not reasonable, the concrete will appear segregation.
