Organic fertilizer screening device

According to the organic fertilizer screening device, organic fertilizer is put into a feeding bin, two first smashing rollers in a coarse smashing cavity rotate to drive driven smashing teeth and driving smashing teeth to rotate, and due to the fact that the driving smashing teeth are meshed with the driven smashing teeth, the organic fertilizer can be coarsely smashed; the organic fertilizer obtained after coarse crushing falls into the fine crushing cavity from the first filter screen to be crushed, fine crushing teeth in the fine crushing cavity further crush the organic fertilizer, crushed organic powder falls into the granulation cylinder from the second filter screen, the organic powder can be extruded into holes in the rotating process of the roller, and the organic powder is extruded out of the holes, so that the granulation efficiency is improved. And the particles fall into a collecting bin. 本实用新型公开了一种有机肥料筛分装置，将有机肥料投入加料仓，粗粉碎腔内的两个第一粉碎辊转动，带动从动粉碎齿和主动粉碎齿转动，由于主动粉碎齿与从动粉碎齿相啮合，能够对有机肥料进行粗粉碎；粗粉碎后的有机肥料从第一过滤网落
