I believe many friends have seen pouring concrete on the roadside. Curiously, it's too wasteful. Don't you want such a load of concrete?

混凝土攪拌車在運(yùn)輸過(guò)程中，有時(shí)候也會(huì)出現(xiàn)各種故障或者長(zhǎng)時(shí)間堵車等情況，這就會(huì)讓混凝土凝固在罐體中，出現(xiàn)悶罐現(xiàn)象。

During the transportation of concrete mixer truck, sometimes there will be various faults or traffic jam for a long time, which will make the concrete solidify in the tank and lead to the phenomenon of tank stuffing.

那么為何寧愿倒掉也不能悶罐呢？

So why would you rather pour it out than stuffy it?

出現(xiàn)這種情況后人們也想出了很多辦法，有采用在罐體某個(gè)位置切一個(gè)洞，然后人工用風(fēng)鎬將里面的混凝土一點(diǎn)點(diǎn)的清理出來(lái)，再把開(kāi)孔焊接封上。

After this situation, people have also come up with many methods. They cut a hole in a certain position of the tank, and then manually clean out the concrete in it with an air pick, and then weld and seal the opening.

也有利用破壁機(jī)配合水鉆打孔，這樣能夠減少粉塵和沙石飛濺，然后從出料口排出，這種方法效率也較高。

Some also use the wall breaking machine to cooperate with the water drill to drill holes, which can reduce the dust and sand splash, and then discharge it from the discharge port. This method is also more efficient.

還有就是利用熱脹冷縮的方法，即便是罐內(nèi)被堵住，但罐內(nèi)還是會(huì)有空間，用油燒混凝土后迅速澆水冷卻，混凝土?xí)兇?，這樣也更容易清理。

There is also the method of thermal expansion and cold contraction. Even if the tank is blocked, there will still be space in the tank. After burning the concrete with oil, water it quickly for cooling, and the concrete will become brittle, which is easier to clean.

據(jù)說(shuō)國(guó)外也有直接用火藥來(lái)炸的，但是這是需要非常有經(jīng)驗(yàn)的人才能操作，而且風(fēng)險(xiǎn)也是很大的，當(dāng)然了，省事的辦法就是直接換一個(gè)罐體。

It is said that foreign countries also directly use gunpowder to explode, but this requires very experienced people to operate, and the risk is also great. Of course, the easy way is to directly change a tank.

清理悶罐的費(fèi)用根據(jù)不同的地方和清理的方法，收取的費(fèi)用也很高。還有就是經(jīng)過(guò)清理后的罐體或多或少都有損壞，使用壽命也將變短。

The cost of cleaning the stuffy tank is also very high according to different places and cleaning methods. In addition, the cleaned tank is more or less damaged, and the service life will be shortened.

混凝土攪拌車的結(jié)構(gòu)

Structure of concrete mixer

罐體外殼是由非常耐磨的鋼材制成的，為了能夠自動(dòng)裝卸混凝土，內(nèi)部還焊有特殊形狀的旋轉(zhuǎn)葉片，轉(zhuǎn)動(dòng)時(shí)混泥土?xí)S著葉片旋轉(zhuǎn)的方向運(yùn)動(dòng)，在不斷的旋轉(zhuǎn)和翻動(dòng)過(guò)程中讓各種材料充分混合和攪拌。

The shell of the tank body is made of very wear-resistant steel. In order to automatically load and unload the concrete, a rotating blade with special shape is welded inside. When rotating, the concrete will move in the direction of blade rotation, and various materials will be fully mixed and stirred in the process of continuous rotation and overturning.

在進(jìn)料和運(yùn)輸過(guò)程中罐體正轉(zhuǎn)，混凝土?xí)S葉片向里運(yùn)動(dòng)，在出料過(guò)程中，罐體則會(huì)反轉(zhuǎn)，混凝土沿著葉片向外將卸出。

In the process of feeding and transportation, the tank rotates forward, and the concrete will move inward with the blade. In the process of discharging, the tank will reverse, and the concrete will be discharged outward along the blade.

罐體的旋轉(zhuǎn)則是靠著卡車上的液壓驅(qū)動(dòng)系統(tǒng)來(lái)完成的，通常都是通過(guò)卡車上的動(dòng)力輸出軸帶動(dòng)液壓泵從而驅(qū)動(dòng)攪拌罐體旋轉(zhuǎn)的。

The rotation of the tank is completed by the hydraulic drive system on the truck. Usually, the hydraulic pump is driven by the power take-off shaft on the truck to drive the mixing tank to rotate.

我們經(jīng)常能夠在各種報(bào)道中看到關(guān)于混凝土攪拌車的各種交通事故，也造成了很多的傷亡，其主要有這些原因，混凝土攪拌車的整個(gè)底盤(pán)都非常的高，駕駛員在操作過(guò)程中就會(huì)出現(xiàn)很多的盲區(qū)，特別是轉(zhuǎn)彎的時(shí)候。

We can often see various traffic accidents of concrete mixer truck in various reports, which also caused a lot of casualties. These are the main reasons. The whole chassis of concrete mixer truck is very high, and the driver will have a lot of blind spots in the process of operation, especially when turning.

還有就是混凝土攪拌車的速度都普遍較快，加上車身和載有很重的混凝土，制動(dòng)距離就會(huì)變長(zhǎng)等，都是造成事故多發(fā)的原因。

In addition, the speed of concrete mixer truck is generally fast. In addition, the braking distance will become longer due to the body and heavy concrete, which are all the reasons for the frequent occurrence of accidents.
