It is mainly used for paving roads. Different types of asphalt concrete have different production standards. The main difference lies in the different particle sizes of the aggregates used. In the production process of asphalt concrete, it is necessary to screen the corresponding aggregates for different types of asphalt concrete through a vibrating screen device.

[0003] The existing authorized Chinese utility model announcement number is: CN210523044U, and the publication date is: 2020-05-15. It discloses an asphalt concrete aggregate vibrating screen, which can have a certain blocking effect on the aggregate sliding process through the setting of the baffle mechanism, prolong its sliding path, and then prolong its screening time in the sliding process, so that the aggregate screening can be more sufficient and avoid secondary screening; at the same time, the inclination angle of the baffle in the baffle mechanism can be adjusted as needed, and then the screening time can be adjusted according to different actual production conditions to meet different production needs.

[0004] The above scheme can be easily adjusted during the screening process to increase the screening time, thereby achieving the effect of fine screening. During the screening process, the screen moves within a certain trajectory and is difficult to remove. The mesh of the screen will be blocked to a certain extent during continuous work. If it cannot be removed conveniently, the continuously blocked screen will affect the screening effect. Therefore, it needs to be further improved and optimized. Utility Model Content
