In the urban planning and construction of infrastructure ground, roads and bridges, housing, concrete mixing plant and water conservancy and hydropower engineering projects, concrete mixing plant truck is an indispensable common transportation tool, especially small concrete mixing truck, because of its narrow body, short wheelbase, small turning radius and other emotional design scheme characteristics, Therefore, it has a strong advantage in the working environment of height limitation, width and length. So, how does the small concrete mixer with perfect function work?

小型混凝土混凝土搅拌车基本原理是由汽车底盘提供推动力来控制器液压传动系统系统软件的变量柱塞泵，把机械设备机械能转成四柱液压机能传送给定性分析电动机，接着再将依据减速机促进拌和筒转动，从而对混泥土进行强制拌和，使它在独特时间内不易凝固。由于其上述的工作上特点，一般根据对混泥土运送间隔的长短、工程施工施工工地规范以及对混泥土质量和配置不一样情况的要求，一般选用2种不一样工作方式。

The basic principle of the small concrete mixer is that the chassis of the truck provides the driving force to control the variable piston pump of the hydraulic transmission system software. The mechanical energy of the mechanical equipment is transformed into a four column hydraulic function and transmitted to the qualitative analysis motor. Then the reducer is used to promote the rotation of the mixing drum, so as to force the concrete mixing, So that it is not easy to solidify in a unique time. Because of the above working characteristics, generally according to the length of concrete transportation interval, construction site specifications and the requirements of different concrete quality and configuration, two different working methods are selected.

1.预拌混凝土的拌和运送。将在混凝土搅拌站拌和好的混泥土马上放进混凝土搅拌车中运送，在小型混凝土混凝土搅拌车运送半途，拌和筒大约以1～3r/min传动比转动，使筒内混泥土不断拌和，避免混凝土裂缝情况，以保证混泥土质量。这类方法运送混泥土的间隔不宜过长，一般控制在混泥土初凝以前，根据混泥土配置和交通路况、平均气温等规范可定好间距或时间。

1. Mixing and transportation of ready mixed concrete. The concrete mixed in the concrete mixing plant will be immediately put into the concrete mixer truck for transportation, and the mixing drum will rotate at a transmission ratio of 1-3r / min in the middle of the transportation of the small concrete mixer truck, so as to continuously mix the concrete in the drum, avoid concrete cracks, and ensure the concrete quality. The interval of transporting concrete by this method should not be too long. Generally, it should be controlled before the initial setting of concrete. The interval or time can be determined according to the concrete configuration, traffic conditions, average temperature and other specifications.

2.混泥土搅拌料的拌和运送。一般有2种情况：颗粒物料和水料拌和运送。颗粒物料注水拌和运送：在调味品站将石料、混泥土等颗粒物料按混泥土配置加上拌和筒内，再将拌和饮用水加上车内储储水箱，在半途适当的间隔或时间将水喷入筒内，对混泥土进行拌和，也可去施工施工工地后拌和。水料拌和运送：在调味品站将石料砂石料、混泥土和水等搅拌料按配置此外放进拌和筒内，拌和筒在运送半途以8～12r/min的传动比转动，对搅拌料进行拌和，开展拌和工作中。

2. Mixing and transportation of concrete mixture. There are generally two cases: mixing and transportation of granular materials and water materials. Water injection mixing and transportation of granular materials: add stone, concrete and other granular materials into the mixing drum according to the concrete configuration in the condiment station, and then add the mixing drinking water into the internal water storage tank of the truck, and spray the water into the drum at appropriate intervals or time halfway to mix the concrete, or go to the construction site for mixing. Mixing and transportation of water materials: in the condiment station, the mixing materials such as aggregate, concrete and water are put into the mixing drum according to the configuration. The mixing drum rotates with a transmission ratio of 8-12r / min during the transportation to mix the mixing materials and carry out the mixing work.

当然，要想更各个方面地充分运用小型混凝土混凝土搅拌车的功效和优势，进熟悉混凝土搅拌车的基本原理仍是不够的，更重要的是掌握适当操作流程，并提高对混凝土搅拌车的维修保养和检查维修，仅有那般才能够保证混凝土搅拌车从始终运行在好状况。

Of course, in order to make full use of the efficacy and advantages of small concrete mixer in all aspects, it is not enough to be familiar with the basic principles of concrete mixer. The more important thing is to master the appropriate operation process and improve the maintenance and inspection of concrete mixer. Only in that way can we ensure that the concrete mixer runs well from beginning to end.
