[0003] The existing crushing device for fertilizer processing has the problem that it is inconvenient to remove the filter screen. For example, the Chinese utility model patent with authorization announcement number CN216654856U discloses a crushing device for fertilizer processing, including a body, a support frame is fixedly connected to the bottom of the body, and a discharge port is opened at the bottom of the body, a motor is installed at the top center of the body, a rotating shaft is connected to the bottom of the motor, the rotating shaft passes through the body and extends to the inside of the body, a screen is installed inside the body, and a crushing blade is installed on the rotating shaft above the screen. The crushing device for fertilizer processing is provided with a motor, which drives the rotating shaft to rotate, thereby driving the crushing blade to cut and crush the fertilizer raw materials. Through the screening and filtering of the screen inside the machine body, the raw materials of qualified size pass through the screen and enter the bottom of the machine body, and the fertilizers of unqualified size continue to stay above the screen for crushing, so that the crushing is more sufficient, and the quality of the crushed materials is guaranteed. The scraper driven by the motor rotates so that the scraper head at the bottom of the scraper scrapes off the fertilizer adhered to the surface of the screen to avoid the fertilizer blocking the screen. However, this device is not convenient for removing the filter. Therefore, we propose a crushing device for fertilizer processing to solve the above-mentioned problems. Utility Model Content
