混凝土自上料攪拌車是用來運送攪拌建筑用混凝土的專用卡車，這類卡車上都裝置圓筒型的攪拌筒以運載混合后的混凝土。在運輸過程中會始終保持攪拌筒轉動，以保證所運載的混凝土不會凝固。那么混凝土自上料攪拌車的專用機構包含什么？混凝土自上料攪拌車廠家為您講解。

The concrete self loading mixer truck is a special truck used to transport and mix the concrete for construction. Cylindrical mixing drums are installed on these trucks to carry the mixed concrete. During transportation, the mixing drum will always be kept rotating to ensure that the concrete carried will not solidify. What is the special mechanism of concrete self loading mixer? The concrete self loading mixer manufacturer will explain it to you.

（1）取力裝置

(1) Power take-off device

混凝土攪拌運輸車采用主車發動機取力方式。取力裝置的作用是通過操縱取力開關將發動機動力取出，經液壓系統驅動攪拌筒，攪抖筒在進料和運輸過程中正向旋轉，以利于進料和對混凝土進行攪拌，在出料時反向旋轉，在工作終結后切斷與發動機的動力聯接。

The concrete mixer truck is powered by the main truck 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 and drive the mixing drum through the hydraulic system. The mixing drum rotates in the forward direction during the feeding and transportation process to facilitate the feeding and mixing of concrete. It rotates in the reverse direction during the discharging and cuts off the power connection with the engine after the work is completed.

（2）液壓系統

(2) Hydraulic system

將經取力器取出的發動機動力(一般都是后置全功能取力器)，轉化為液壓能(排量和壓力)，再經馬達輸出為機械能(轉速和扭矩)，為攪拌筒轉動提供動力。

The engine power taken out by the power take-off (generally the 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.

（3）減速機

(3) Reducer

將液壓系統中馬達輸出的轉速減速后，傳給攪拌筒。

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

（4）操縱機構

(4) Control mechanism

控制攪拌筒旋轉方向，使之在進料和運輸過程中正向旋轉，出料時反向旋轉。

Control the rotation direction of the mixing drum to make it rotate forward during feeding and transportation and reverse during discharging.

控制攪拌筒的轉速。

Control the rotation speed of the mixing drum.

（5）攪拌裝置

(5) 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，它是由優質耐磨薄鋼板制成，為了能夠自動裝、卸混凝土，其內壁焊有特殊形狀的螺旋葉片。轉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，混凝土沿葉片向里運動，出料時，攪拌筒反轉，混凝土沿著葉片向外卸出。攪拌筒的轉動則是靠液壓驅動裝置來保證。裝載量為3~6立方。的混凝土攪拌運輸車一般采用由汽車發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致混凝土攪拌不均勻。另外，葉片的角度如果設計不合理，還會使混凝土出現離析。

It is mainly composed of a mixing drum and its auxiliary supporting parts. The mixing drum is a concrete loading container, which is made of high-quality wear-resistant steel sheet. In order to automatically load and unload concrete, its inner wall is welded with special spiral blades. During rotation, 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. The rotation of the mixing drum is ensured by the hydraulic driving device. The loading capacity is 3 ~ 6 cubic meters. Generally, the truck 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 truck with a loading capacity of 9 ~ 12 cubic meters, the truck auxiliary diesel engine drives the hydraulic pump to drive the hydraulic motor. The blade is the main part of the mixing device. Damage or serious wear will cause uneven mixing of concrete. In addition, if the blade angle is not designed properly, the concrete will be separated.

（6）清洗系統

(6) Cleaning system

清洗系統的主要作用是清洗攪拌筒，有時也用于運輸途中進行干料攪拌。清洗系統還對液壓系統起冷卻作用。

The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used for dry material mixing during transportation. The cleaning system also cools the hydraulic system.

（7）封閉裝置

(7) Closure

全封閉裝置采用回轉密封技術，密封了攪拌車的進出料口，解決了傳統攪拌車水份蒸發、砂漿分層、砼料撒落、行車安全等系列問題。

The fully enclosed device adopts the rotary sealing technology to seal the inlet and outlet of the mixer truck, and solves a series of problems such as water evaporation of the traditional mixer truck, mortar layering, concrete material scattering and driving safety.

專用機構主要包括取力器、攪拌筒前后支架、減速機、液壓系統、攪拌筒、操縱機構、清洗系統等。其工作原理:通過取力裝置將汽車底盤的動力取出，并驅動液壓系統的變量泵，把機械能轉化為液壓能傳給定量馬達，馬達再驅動減速機，由減速機驅動攪拌裝置，對混凝土進行攪拌。更多相關內容就來我們網站http://www.xiaoplaoshi.cn咨詢了解。

The special mechanism mainly includes power takeoff, front and rear supports of mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc. Its working principle: the power of the automobile chassis is taken out by the power take-off device, and the variable pump of the hydraulic system is driven to convert the mechanical energy into hydraulic energy and transmit it to the quantitative motor. The motor then drives the reducer, and the reducer drives the mixing device to mix the concrete.
