At the same time, when granulating the lignite fertilizer, the screen 203 can also be driven to slide up and down by the operation of the granulator body 1, so as to better screen the lignite fertilizer. The first spring 212 fixed to the side end of the limit block 209 can drive the interference rod 206 to slide upward after the interference rod 206 slides upward. 206 and the screen 203 slide back, and the granulated lignite fertilizer can be diverted by the blocking rod 210 fixed to the side end of the screen 203; the screening box 201 can be positioned by plugging the clamping rod 211 fixed to the top of the screening box 201 and the granulator body 1; when too much granulated lignite fertilizer is screened, the rotating plate 302 is driven to rotate and fall by the rotating rod 301, so that the unqualified lignite fertilizer can be processed again, and the clamping block 303 is driven to plug into the rotating plate 302 by the second spring 304, so that the rotating plate 302 can be limited and fixed; because the area of ​​the discharge port 6 is smaller than the area of ​​the rotating plate 302, when the rotating plate 302 rotates upward to a certain extent, the top surface of the rotating plate 302 and the partition 5 conflict with each other, so that the rotating plate 302 It fits tightly with the partition 5 to prevent the lignite fertilizer from flowing out of the screening box 201; when the screening box 201 is installed at the bottom end of the granulator body 1, the screening box 201 is fixed to the granulator body 1 through the side plate 4, making the installation of the screening box 201 more stable and firm.
