[0002] In modern construction engineering, the quality of concrete directly affects the safety and durability of the project. In order to ensure the uniformity and suitable particle distribution of concrete, screening equipment plays a crucial role. Traditional concrete raw material screening equipment usually only has basic screening function, mainly relying on screen to test and separate raw materials.

[0003] The design of traditional screening equipment is often simple, usually composed of fixed screen and vibrating device. When dealing with conventional particle size of concrete raw materials, this kind of equipment can effectively complete the screening task. However, when encountering large particle raw materials, due to the limited aperture of the screen, these large particles are often stuck on the screen, causing the screen to block. This blockage not only affects the liquidity of the material, forces the equipment to stop for cleaning, but also makes the subsequent cleaning work extremely troublesome. Once the screen is blocked, the production efficiency will be greatly reduced, and manual cleaning is necessary, wasting production time. In addition, during the cleaning process, the operator may also face safety hazards, especially in the case of large particle raw materials that are difficult to move. More seriously, the traditional equipment often lacks an effective recovery mechanism for unqualified particle size raw materials. These screened large particle raw materials are usually directly discarded, leading to resource waste and cost increase. SUMMARY
