Description

Technical Field

[0002] Ready-mixed concrete refers to a concrete mixture that is made of cement, aggregate, water, and admixtures and mineral admixtures added as needed, in a certain proportion, and is sold after being measured and mixed at a mixing station and transported to the place of use within a specified time by a transport vehicle. It can be roughly divided into two types: ordinary concrete (cement concrete) and special concrete (such as waterproof concrete, heat-resistant concrete, hydraulic concrete, etc.).

[0003] During the transportation of ready-mixed concrete, impurities need to be filtered out through a filtering device. The existing patent application number is CN 202223472731.5, which discloses a device for filtering coarse impurities in ready-mixed concrete. The connecting rod drives the sieve plate to move through the connecting block to achieve a vibration effect, thereby improving the filtering effect. However, when the sieve plate is used to filter impurities in ready-mixed concrete for a long time, impurities are easily accumulated in the mesh of the sieve plate, affecting the filtering effect, and manual cleaning is inconvenient.
