[0025] In this embodiment: Under normal circumstances, in order to ensure that the quality and size of the crushed stone meet the engineering requirements, it is usually necessary to separate the crushed stones of different sizes through the screening process. Screening is usually carried out using a vibrating screen with screens of different apertures to effectively classify the crushed stone particles. However, during the screening process, especially when dealing with crushed stone, a common problem is that the crushed stone is blocked at the top of the screen, causing it to be unable to pass through the screen smoothly and fall below. Once the screen is blocked, the operation of the screening machine must be stopped and the crushed stone on the screen must be manually cleaned, which not only reduces the operating efficiency, but also increases the labor intensity and production cost. Then, by adding a concrete raw material screening anti-blocking mechanism 3, the screen can be driven to vibrate by vibration, thereby screening the raw materials, and when blockage occurs, the screen can be turned over and then vibrated, thereby conveniently clearing the blocked foreign matter, and the efficiency is better.
