[0051] The implementation principle of a screening machine in an embodiment of the present application is as follows: when it is necessary to screen the material, first, start the feeding component 4, the rotating motor 423 drives the rotating rod 421 to rotate, which can drive the blade 422 to rotate, inject the crushed material into the feeding box 41, and perform secondary crushing on the material by the blade 422. At the same time, start the water pump 535 in the dust reduction component 5, and the water in the water tank 531 is sprayed onto the material through the atomizing nozzle 534. Subsequently, the sprayed material enters the drum screen 22. During this process, start the driving component 3, and the driving component 3 drives the drum screen 22 to rotate. During the rotation of the drum screen 22, the material can be screened, and the screened material slides into the designated container through the unloading piece 26 to complete the screening of the material.

[0052] When the crushed material enters the feeding box 41, it is crushed for the second time by the blade 422. Then, the material flows to the bottom of the feeding box 41, and the water pump 535 pumps the water in the water tank 531 into the horizontal pipe 532, and sprays it out through the atomizing nozzle 534, so as to spray the material. The sprayed material slides into the drum screen 22 through the first filter screen 51, and the sprayed water passes through the first filter screen 51 and the second filter screen 52 and is recycled in the water tank 531.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
