The power take-off drives the hydraulic motor of the hydraulic pump to rotate through the small transmission shaft, and drives the mixing drum to rotate through the reducer. During the transportation of concrete, it is necessary to keep the mixing tank rotating at a low speed of 1-3 revolutions per minute to ensure the uniformity of concrete and prevent concrete segregation, which is called stirring (commonly known as mixing).

攪拌車在裝混凝土的時(shí)候攪拌罐轉(zhuǎn)速較快，速度為每分鐘6-10轉(zhuǎn)，混凝土通過裝料系統(tǒng)從筒口導(dǎo)管進(jìn)入攪拌筒，并在螺旋葉片引導(dǎo)下，流向攪拌筒的中下部。注意：裝料時(shí)與運(yùn)輸過程中罐體的轉(zhuǎn)動(dòng)方向應(yīng)保持一致，否則在運(yùn)輸過程中會(huì)將混凝土卸出。

When the mixer truck 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. Note: the rotation direction of the tank body during loading shall be consistent with that during transportation, otherwise the concrete will be unloaded during transportation.

攪拌車在卸料時(shí)，發(fā)動(dòng)機(jī)將動(dòng)力通過取力器，液壓泵，減速機(jī)等傳輸?shù)綌嚢韫蓿瑤?dòng)罐體轉(zhuǎn)動(dòng)，速度為3-14轉(zhuǎn)/分；混凝土在 葉片螺旋運(yùn)動(dòng)的頂推作用下向筒口方向移動(dòng)，經(jīng)過攪拌車的卸料斗卸出。此時(shí)罐體的轉(zhuǎn)動(dòng)方向與進(jìn)料時(shí)的方向相反。

When the mixer truck is unloading, the engine transmits the power to the mixing tank through the power take-off, hydraulic pump and reducer to drive the tank to rotate at a speed of 3-14 rpm; The concrete moves towards the cylinder mouth under the pushing action of the blade spiral movement and is discharged through the discharge hopper of the mixer truck. At this time, the rotation direction of the can body is opposite to that during feeding.

通過制動(dòng)系統(tǒng)的儲(chǔ)氣筒給水罐加壓，水流經(jīng)過加壓清洗攪拌罐系統(tǒng)，裝料口，卸料系統(tǒng)等。

Pressurize the water tank through the air reservoir of the braking system, and the water flows through the pressurized cleaning mixing tank system, loading port, unloading system, etc.

這些知識(shí)相對攪拌車的使用者來說可能先對比較的簡單，但對于沒有接觸過，想進(jìn)入攪拌車行業(yè)的初學(xué)者來說還是可以認(rèn)真看看，學(xué)習(xí)的。如果文中有什么錯(cuò)誤，也希望大家及時(shí)討論指正。

These knowledge may be relatively simple for the users of the mixer truck, but for the beginners who have not contacted and want to enter the mixer truck industry, they can still take a serious look and learn. If there are any mistakes in the text, I hope you can discuss and correct them in time.
