The manufacturer of full-automatic self loading mixer is composed of automobile chassis and special equipment for concrete mixing and transportation. A special truck used to transport concrete for construction; Because of its shape, it is often called snail car. The working principle is that the power of the automobile chassis is taken out through 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.

一、把搅拌车开到搅拌站加料漏斗下，使车的进料斗口与搅拌站的出料漏斗口对正，防止混凝土流到车外面造成浪费和污染车体。

1、 Drive the mixer truck under the charging hopper of the mixing plant to align the inlet hopper of the truck with the outlet hopper of the mixing plant, so as to prevent the concrete from flowing outside the truck, causing waste and polluting the car body.

二、把操纵油泵伺服阀的手柄放在位置，此时搅拌筒处于静止状态

2、 Place the handle of the servo valve of the oil pump at the central position, and the mixing drum is at a standstill

三、料装到公称搅动容量时，操纵手柄，将发动机转速调为1800r/min时,使搅拌筒的搅动转速为1~3r/min，使发动机转速为小后，然后在驾驶室锁住手柄，把车开交货地点。从进料开始到卸料完毕允许的时间为1.5小时或拌筒旋转300转（取其中时间短者）。

3、 When the material is loaded to the nominal stirring capacity, operate the handle. When the engine speed is adjusted to 1800r / min, the stirring speed of the mixing drum is 1 ~ 3R / min. after the engine speed is small, lock the handle in the cab and drive the vehicle to the delivery place. The allowable time from the beginning of feeding to the end of unloading is 1.5 hours or 300 revolutions of mixing drum (whichever is shorter).

四、搅拌车满载上坡应适当使拌筒旋转速度加快。

4、 When the mixer truck goes uphill with full load, the rotation speed of the mixing drum shall be properly accelerated.

五、在操纵车辆尾部两侧手柄前，应解开驾驶室操纵定位锁紧板，才能实现拌筒尾部正反转操作。然后根据工地要求的速度进行卸料。

5、 Before operating the handles on both sides of the rear of the vehicle, the cab operation positioning locking plate shall be loosened to realize the forward and reverse operation of the rear of the mixing drum. Then discharge according to the speed required by the construction site.

六、每次卸料后，将进料斗，搅拌筒内外，出料溜槽等清洗干净，防止混凝土凝固在上述部件上。

6、 After each unloading, clean the feed hopper, inside and outside of the mixing drum and the discharge chute to prevent the concrete from solidifying on the above parts.

全自动自上料搅拌车的日常维护和保养也很重要：

The daily maintenance of the full-automatic self feeding mixer is also very important:

一、车内保养，包括：润滑系、燃油系、冷却系、制动系、化油器（喷油嘴）的保养等。

1、 In car maintenance, including maintenance of lubrication system, fuel system, cooling system, braking system, carburetor (fuel nozzle), etc.

二、车体保养，包括车漆、坐垫地毯、保险杠、车裙、仪表台、轮胎、轮毂、挡风玻璃、底盘等。

2、 Car body maintenance, including car paint, cushion carpet, bumper, skirt, dashboard, tire, wheel hub, windshield, chassis, etc.

三、搅拌车刹车系统对于汽车行驶的性关重要。还要经常检查打气泵的工作情况及气泵皮带的磨损，及时更换。

3、 The brake system of mixer truck is very important for the stability of vehicle. Also check the working condition of the air pump and the wear of the air pump belt frequently, and replace it in time.

四、行驶一定里程后调换前后轮胎，这样可以物尽其用，延长轮胎的使用寿命。

Four, after a certain mileage, change the front and rear tires, so that we can make the best use of the tire and prolong the service life of the tire.

五、注意雨刷的保养，原厂都已对洗刷视野做出了设计，私自加长雨刮片长度虽然可以增加车窗视野的可见范围，但相对地也会加大雨刮器电机等电器设备的负担。

5、 Pay attention to the maintenance of the wiper. The original factory has designed the cleaning field of vision. Privately lengthening the length of the wiper blade can increase the visible range of the window field of vision, but it will also add the burden of electrical equipment such as heavy rain wiper motor.
