自動上料攪拌車粘罐原因可以分為兩大類：即設計不合理和使用不當，主要有以下幾種形式：
Through practice and analysis, we believe that the reasons for the tank sticking of the automatic feeding mixer can be divided into two categories: unreasonable design and improper use, mainly in the following forms:
（1）卸料殘余率和葉片設計的不合理。從攪拌筒的內部結構看，自動上料攪拌車的拌筒是依靠回轉的筒體帶動其中的兩條螺旋葉片所產(chǎn)生的螺旋運動，使混凝土獲得既有“切向”又有“軸向”的復合運動，從而使攪拌筒具有攪拌和卸料的功能，因此形成這一螺旋運動的有關因素，諸如螺旋葉片的曲線參數(shù)，攪拌筒的幾何形狀和尺寸等對攪拌車的卸料殘余率都有重要影響。
(1) Unreasonable discharge residual rate and blade design. From the perspective of the internal structure of the mixing drum, the mixing drum of the automatic feeding mixer relies on the spiral motion generated by the two spiral blades driven by the rotating drum, so that the concrete can obtain both "tangential" and "axial" composite motion, so that the mixing drum has the function of mixing and unloading. Therefore, the relevant factors that form this spiral motion, such as the curve parameters of the spiral blades, The geometry and size of the mixing drum have an important influence on the discharge residual rate of the mixer truck.
而過大的卸料殘余率意味著攪拌車在卸料結束后在自動上料攪拌車里會有更多的余料，因而更有可能因日積月累在攪拌罐中粘料。目前大多數(shù)廠家采用的是等角對數(shù)螺旋線葉片，在卸料殘余率上還有很大的改進空間。
However, the excessive discharge residual rate means that there will be more surplus materials in the automatic loading mixer after the unloading of the mixer truck, so it is more likely that the materials will stick in the mixing tank due to accumulation over time. At present, most of the manufacturers use equiangular logarithmic spiral blades, and there is still a lot of room for improvement in the discharge residual rate.
（2）自動上料攪拌車工作環(huán)境溫度過高。夏季在南方地區(qū)白天中午前后，環(huán)境溫度經(jīng)常超過30℃，在這種情況下運輸混凝土，將會由于混凝土坍落度損失快以及罐體周圍溫度相對中心更高，因而混凝土更容易粘罐。
(2) The working environment temperature of the automatic feeding mixer is too high. In summer, around noon in the south, the ambient temperature often exceeds 30 ℃. In this case, the concrete will be more easily stuck to the tank due to the rapid loss of concrete slump and the higher temperature around the tank.
（3）運輸距離過長。隨著城市化的進程及城市規(guī)劃的要求，越來越多的攪拌站被要求遷到郊區(qū)和郊縣，與市區(qū)的距離越來越遠，而由于混凝土這一產(chǎn)品的特殊性，任何預拌混凝土在未添加緩凝劑的情況下，都在1h左右進入初凝狀態(tài)，如果這時才進行混凝土澆注施工，不但影響混凝土的工程質量。
(3) The transportation distance is too long. With the process of urbanization and the requirements of urban planning, more and more mixing plants are required to move to the suburbs and counties, and the distance from the urban area is getting farther and farther. Due to the particularity of concrete, any ready mixed concrete will enter the initial setting state within 1h without adding retarder. If the concrete pouring construction is carried out at this time, it will not only affect the quality of the concrete project.
而且因混凝土失去流動性，易在攪拌筒及葉片上凝結，導致粘罐，嚴重時甚整車混凝土粘在罐內及造成液壓設備的損壞，所以自動上料攪拌車運送預拌混凝土有其時間控制的輸送半徑，一般應控制在1h以內。
Moreover, since the concrete loses fluidity, it is easy to coagulate on the mixing drum and blades, resulting in tank sticking. In serious cases, even the whole vehicle of concrete is stuck in the tank and the hydraulic equipment is damaged. Therefore, the transportation radius of the automatic loading mixer truck for transporting the ready mixed concrete has its time control, which should generally be controlled within 1h.
此外自動上料攪拌車駕駛員在攪拌車卸料完畢后未及時清理清洗攪拌罐內及葉片上殘留的混凝土，在攪拌車回站過程中不轉動攪拌罐，殘留的混凝土干燥后凝固在拌筒及葉片上，以后就會越聚越多，形成粘罐現(xiàn)象。所以要及時進行清理才行，詳情就來我們網(wǎng)站

In addition, the driver of the automatic loading mixer truck failed to clean the residual concrete in the mixing tank and on the blades in time after the unloading of the mixer truck, and did not rotate the mixing tank during the return of the mixer truck to the station. After drying, the residual concrete was solidified on the mixing drum and the blades, and then it would gather more and more, forming the phenomenon of tank sticking. So we need to clean it up in time. Please come to our website for details http://www.fxsgujg.cn Consult.
