[0002] With the development of modern society, rubber products are widely used in various aspects of industry or life. When producing rubber, it is necessary to crush the raw materials. The rubber particles obtained after the existing rubber raw materials are crushed by the crushing device may be of different sizes. Some of the crushed raw materials cannot be put into the subsequent process, resulting in poor crushing effect. The different sizes of rubber particles may affect the time required for subsequent processing of the rubber particles. Announcement No. CN214266265U discloses a rubber raw material crushing device for rubber production. In actual use, the device needs to open the recovery port to collect large rubber particles and then perform secondary processing, which is troublesome and inconvenient, prolonging the production time and thus slowing down the production efficiency.
