I believe you must have seen a super large truck on the road. Behind this kind of truck is a big drum like a snail, and the drum is spinning. You must be puzzled. What kind of car is this? It turns out that this is a special transport vehicle used to transport the most commonly used raw materials for construction sites, concrete, why do the rollers behind it rotate? Why do I leave behind these puzzles and mysteries?
The first is its working principle: power plant. The engine powers the mixer and stirs the concrete through a hydraulically driven mixer drum. You must be wondering, then, what exactly is the hydraulic system? The hydraulic system is powered by a force-retrieving device and then converted to hydraulic energy. The motor outputs mechanical energy. This series of kinetic energy provides power to the mixing drum. The mixing drum is rotated forward during the feeding of raw materials and during transportation, so as to facilitate the feeding and agitation of the concrete so that it will not condense during transportation and reach the construction site in the opposite direction when the raw material is delivered. .
Followed by its use: The first use is wet material delivery. In layman's terms, it is to mix concrete raw materials directly from the concrete factory into the mixer drum. In order not to solidify the concrete, the transport truck ensures that the speed of the mixer drum is consistent with the feed rate. During transport, the mixer drum is constantly stirred slowly. After being transported to the destination by an oversized truck, the mixing drum discharges the concrete for the construction site, which is convenient and effective. The second use is dry material delivery. This means that the raw weighed material is weighed into a mixing drum and transported directly by truck. The water is stirred before reaching the destination of the construction site and can be used by construction sites. After the stirring is completed, invert the material for on-site use. It can be seen that the use of this super-large transporter is very extensive, and it can be described as an artifact that cannot be separated from the construction site.
The above is my introduction, I believe you must have a deeper understanding of this big guy, and also solved the problem of why it has been rotating for many years.
