[0002] Water-soluble fertilizer is a powdered fertilizer that needs to be dissolved in water before use. In the process of processing granular water-soluble fertilizer, a crushing and screening machine is needed to process the water-soluble fertilizer from granules into powder.

[0003] A Chinese patent with announcement number CN220406286U discloses a water-soluble fertilizer crushing and screening machine, including a screening machine structure, sieve holes, a supporting base, a pulling belt, a feed pipe, a discharge pipe, a first motor, a second motor, a second pulling belt, a supporting structure rod, a fixed round rod, a flat screw and a side protective plate. The utility model can block impurities from entering the interior of the screening structure by arranging a feed port and a screening machine structure. The utility model can cooperate with the side protective plate, the screening machine structure, the flat screw and the leakage hole to allow the user to remove the side protective plate and the four-corner screws to clean or repair the screening machine structure according to the internal situation. This solves the problem that when the existing screening machine encounters larger particles of water-soluble fertilizer when adding water-soluble fertilizer, the water-soluble fertilizer larger than the size of the sieve hole can easily pass through the sieve hole and get stuck in the leakage hole.

In the process of crushing granular water-soluble fertilizers, the existing crushing and screening machines usually crush the crushed water-soluble fertilizers. After the fertilizer is screened, unqualified water-soluble fertilizer is poured back into the crushing structure for re-crushing, resulting in low crushing efficiency. The granular water-soluble fertilizer is poured into the door cover 21 from the feed hopper 22, and then enters the casing 3 from the feed port 23 of the door cover 21. The motor 8 is operated to drive the rotating rod 5 to rotate, and the rotating rod 5 drives the moving disk 6 to rotate. The moving disk 6 drives the moving needle 19 and the outer tooth 20 thereon to rotate. The moving needle 19 and the outer tooth 20 cooperate with the inner gear ring 25 and the outer gear ring 26 on the door cover 21 to crush the granular water-soluble fertilizer. At the same time, the screen 15 is continuously rotated. During the rotation of the screen 15, the material is brought to a high place, and then the material moves downward under the action of gravity. The material moves to between the moving needle 19 and the outer teeth 20 and the inner and outer gear rings 25 and 26, and is ground by each other for crushing. At the same time, the screen 15 continuously turns over the granular water-soluble fertilizer, and the water-soluble fertilizer of qualified specifications falls from the sieve holes of the screen 15 to the discharge hopper 4 and is discharged from the discharge hopper 4. The unqualified water-soluble fertilizer is crushed by the moving needle 19 and the outer teeth 20 in cooperation with the inner and outer gear rings 25 and 26. This structure integrates crushing and screening, so that the qualified water-soluble fertilizer can be screened, and the unqualified one needs to continue to be crushed, avoiding the unqualified water-soluble fertilizer being returned to the crushing structure after screening, saving the rework step, and helping to improve the efficiency of crushing.
