Description

Concrete anti-accumulation control method, mixer truck and storage medium Technical Field The application relates to the technical field of mixer trucks, in particular to a concrete anti-accumulation control method, a mixer truck and a storage medium. Background In the process of transporting concrete, the concrete attachment and accumulation phenomenon inevitably exist in the stirring cylinder of the concrete stirring truck. Along with the increase of the transportation distance or the extension of the parking time, concrete residual layers with different degrees can be gradually formed on the inner wall of the stirring cylinder and the stirring blades, and long-term accumulation can lead to unbalanced load of the stirring cylinder, lifting of rotation resistance and increase of the load of a hydraulic system, so that the running stability of the whole vehicle is influenced. In the prior art, in order to reduce the adhesion of concrete in a cylinder, the prior art comprises the steps of changing a concrete flow path by optimizing a blade structure in the cylinder, enhancing centrifugal force in a short time by improving stirring rotation speed, reducing adhesion by arranging an internal lining plate, or relying on modes such as high-pressure water flushing during discharging and cleaning. Although these approaches can improve the problem of accumulation under certain conditions, there are significant drawbacks. For example, structural optimization and lining plate adjustment often require modification of the mixing drum, are high in cost and limited in adaptability, increase in rotational speed can cause more energy consumption, are insensitive to concrete property changes, and high-pressure water flushing is performed after stopping, so that accumulation development cannot be slowed down in the transportation process. Some mixer trucks attempt to improve the discharge efficiency by means of mechanical vibrations, which are often noisy, impact on the body structure is significant and the frequency of vibration is difficult to adjust for different concrete types.
