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、把攪拌車開到攪拌站加料漏斗下，使車的進料斗口與攪拌站的出料漏斗口對正，防止混凝土流到車外面造成浪費和污染車體。

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、把操縱油泵伺服閥的手柄放在位置，此時攪拌筒處于靜止狀態

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、料裝到公稱攪動容量時，操縱手柄，將發動機轉速調為1800r/min時,使攪拌筒的攪動轉速為1~3r/min，使發動機轉速為小后，然后在駕駛室鎖住手柄，把車開至交貨地點。從進料開始到卸料完畢允許的時間為1.5小時或拌筒旋轉300轉（取其中時間短者）。

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、攪拌車滿載上坡應適當使拌筒旋轉速度加快。

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

五、在操縱車輛尾部兩側手柄前，應解開駕駛室操縱定位鎖緊板，才能實現拌筒尾部正反轉操作。然后根據工地要求的速度進行卸料。

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，將進料斗，攪拌筒內外，出料溜槽等清洗干凈，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.

全自動自上料攪拌車的日常維護和保養也很重要：

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

一、車內保養，包括：潤滑系、燃油系、冷卻系、制動系、化油器（噴油嘴）的保養等。

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

二、車體保養，包括車漆、坐墊地毯、保險杠、車裙、儀表臺、輪胎、輪轂、擋風玻璃、底盤等。

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

三、攪拌車剎車系統對于汽車行駛的性至關重要。還要經常檢查打氣泵的工作情況及氣泵皮帶的磨損，及時更換。

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、行駛一定里程后調換前后輪胎，這樣可以物盡其用，延長輪胎的使用壽命。

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、注意雨刷的保養，原廠都已對洗刷視野做出了設計，私自加長雨刮片長度雖然可以增加車窗視野的可見范圍，但相對地也會加大雨刮器電機等電器設備的負擔。

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.
