取力裝置
Power take-off device
自上料水泥攪拌車采用主車發(fā)動機取力方式。取力裝置的作用是通過操縱取力開關(guān)將發(fā)動機動力取出，經(jīng)液壓系統(tǒng)驅(qū)動攪拌筒，攪抖筒在進料和運輸過程中正向旋轉(zhuǎn)，以利于進料和對混凝土進行攪拌，在出料時反向旋轉(zhuǎn)，在工作終結(jié)后切斷與發(fā)動機的動力聯(lián)接。
The self feeding cement mixer adopts the power taking mode of main vehicle engine. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch, drive the mixing drum through the hydraulic system, and the mixing drum rotates in a positive direction during feeding and transportation, so as to facilitate feeding and mixing of concrete, rotate in a reverse direction during discharging, and cut off the power connection with the engine after the work is completed.
液壓系統(tǒng)
Hydraulic system
將經(jīng)取力器取出的發(fā)動機動力(一般都是后置全功能取力器)，轉(zhuǎn)化為液壓能(排量和壓力)，再經(jīng)馬達輸出為機械能（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 take-off (generally rear full-function 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.
減速機
Reducer
將液壓系統(tǒng)中馬達輸出的轉(zhuǎn)速減速后，傳給攪拌筒。
The speed output by the motor in the hydraulic system is reduced and transmitted to the mixing drum.
操縱機構(gòu)
Operating mechanism
控制攪拌筒旋轉(zhuǎn)方向，使之在進料和運輸過程中正向旋轉(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 to make it rotate forward during feeding and transportation and reverse during discharging. Control the rotating speed of the mixing drum.
攪拌裝置
Mixing device
它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動，在不斷的提升和翻動過程中受到混合和攪拌。在進料及運輸過程中，攪拌筒正轉(zhuǎn)，混凝土沿葉片向里運動，出料時，攪拌筒反轉(zhuǎn)，混凝土沿著葉片向外卸出。
It is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a container for loading concrete. It 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 blades. During discharging, the mixing drum reverses, and the concrete is discharged outward along the blades.
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立方的自動上料攪拌車一般采用由汽車發(fā)動機通過動力輸出軸帶動液壓泵，再由高壓油推動液壓馬達驅(qū)動攪拌筒，裝載量為9～12立方的則由車載輔助柴油機帶動液壓泵驅(qū)動液壓馬達。葉片是攪拌裝置中的主要部件，損壞或嚴重磨損會導(dǎo)致混凝土攪拌不均勻。另外，葉片的角度如果設(shè)計不合理，還會使混凝土出現(xiàn)離析。
The rotation of the mixing drum is ensured by the hydraulic driving device. The automatic loading mixer with a loading capacity of 3 ~ 6 cubic meters generally adopts 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. The blade is the main component in the 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.
封閉裝置
Closing device
自上料水泥攪拌車全封閉裝置采用回轉(zhuǎn)密封技術(shù)，密封了攪拌車的進出料口，解決了傳統(tǒng)攪拌車水份蒸發(fā)、砂漿分層、砼料撒落、行車安全等系列問題。
The fully enclosed device of the self feeding cement mixer adopts the rotary sealing technology, which seals the inlet and outlet of the mixer, and solves a series of problems such as water evaporation, mortar layering, concrete scattering and driving safety of the traditional mixer.
