自动上料搅拌车的四大功能

所属分类：公司新闻发布时间：2022-05-18 来源：http://www.sqjituan.cn/ 浏览量：0

自动上料搅拌车的搅拌系统可以保证一个半小时内混凝土不产生离析和凝固的现象。自动上料搅拌车有重要的四项功能，分别为：装料功能、搅拌功能、卸料功能、清洗功能。下面对以上功能作简单的介绍。

The mixing system of the automatic loading mixer can ensure that the concrete will not segregate and solidify within one and a half hours. The automatic loading mixer has four important functions: loading function, mixing function, unloading function and cleaning function. The following is a brief introduction to the above functions.

（1）自动上料搅拌车装料功能原理：自动上料搅拌车在装混凝土的时候搅拌罐转速较快，速度为每分钟 6~10 转，混凝土通过装料系统从筒口导管进入搅拌筒，并在螺旋叶片引导下，流向搅拌筒的中下部。装料时与运输过程中罐体的转动方向应保持一致，否则在运输过程中会将混凝土卸出。

(1) Principle of loading function of automatic loading mixer: when the automatic loading mixer is loading concrete, the speed of the mixing tank is fast, with a speed of 6 ~ 10 revolutions per minute. The concrete enters the mixing drum from the barrel opening conduit through the loading system, and flows to the middle and lower part of the mixing drum under the guidance of spiral blades. During loading, the rotation direction of the tank body shall be consistent with that during transportation, otherwise the concrete will be unloaded during transportation.

（2）自动上料搅拌车搅拌功能原理：全功率取力器将发动机的动力取出，全功率取力器是安装在传动轴中间，用一种转换装置，可以实现与发动机的动力断开或者是转速的升降，现有的自动上料搅拌车大对已采用飞轮取力器，从发动机的飞轮取力，取力器将发动机的机械能转换为液压能（排量和压力）。动力由小传动轴传递给液压泵，然后液压马达将液压能再次转换为机械能（转速和扭矩），经过减速机的减速再驱动搅拌筒的旋转，在运输过程中，为了保证混凝土的质量要求搅拌筒能保持每分钟 1~3 分钟的转速转动，这个过程称为搅拌。

(2) Principle of mixing function of automatic feeding mixer: the full power take-off takes out the power of the engine. The full power take-off is installed in the middle of the transmission shaft and can be disconnected from the power of the engine or the rise and fall of speed with a conversion device. Most of the existing automatic feeding mixer have adopted flywheel take-off to take power from the flywheel of the engine, The power takeoff converts the mechanical energy of the engine into hydraulic energy (displacement and pressure). The power is transmitted to the hydraulic pump by the small transmission shaft, and then the hydraulic motor converts the hydraulic energy into mechanical energy (speed and torque) again. After the deceleration of the reducer, the mixing drum is driven to rotate. In order to ensure the quality of concrete during transportation, the mixing drum is required to rotate at a speed of 1 ~ 3 minutes per minute. This process is called mixing.

（3）自动上料搅拌车卸料功能原理：自动上料搅拌车在卸料时，发动机将动力通过取力器，液压泵，减速机等传输到搅拌罐，带动罐体转动，速度为每分钟 3-14 转；混凝土在叶片螺旋运动的顶推作用下向筒口方向移动，经过自动上料搅拌车的卸料斗卸出。此时罐体的转动方向与进料时的方向相反。

(3) Unloading function principle of automatic loading mixer: when the automatic loading mixer is unloading, the engine transmits the power to the mixing tank through power takeoff, hydraulic pump, reducer, etc., driving the tank to rotate at a speed of 3-14 revolutions per minute; Under the pushing action of the blade spiral movement, the concrete moves towards the barrel opening and is discharged through the discharge hopper of the automatic loading mixer. At this time, the rotation direction of the can body is opposite to that during feeding.

（4）自动上料搅拌车清洗功能原理：在每次卸料后，都需要对搅拌筒进行清洗，以防止混凝土沾在搅拌筒内壁上。在减速机上面装有储水器，通过制动系统的储气筒给水罐加压，水流经过加压清洗搅拌罐内壁。

(4) Cleaning function principle of automatic loading mixer: after each unloading, the mixing drum needs to be cleaned to prevent the concrete from sticking to the inner wall of the mixing drum. A water reservoir is installed on the reducer to pressurize the water tank through the air reservoir of the braking system, and the water flows through the pressurization to clean the inner wall of the mixing tank.
