[0026] like Figure 2 , Figure 3 As shown, the screening mechanism 3 is used to screen materials. The screening mechanism 3 includes a primary screening member 31 with a sieve hole, a secondary screening member 32 with a sieve hole, and a driving member 33. The primary screening member 31 is elastically connected to the housing 2, the secondary screening member 32 is rotatably connected to the housing 2, the output end of the driving member 33 is transmission-connected to the secondary screening member 32, and the driving member 33 is used to provide power for the rotation of the secondary screening member 32. The bottom surface of the primary screening member 31 is provided with a plurality of upper contact blocks 34 spaced apart along its circumference. In the present application, two upper contact blocks 34 are spaced apart, and the present application does not make any specific restrictions on this. The top surface of the secondary screening member 32 is provided with a plurality of upper contact blocks 34 spaced apart along its circumference. There is a lower contact block 35, and the bottom surface of the upper contact block 34 and the top surface of the lower contact block 35 are both arc surfaces, which can avoid the upper contact block 34 and the lower contact block 35 from getting stuck when they contact, thereby lifting the first-level screening element 31. The first-level screening element 31 and the second-level screening element 32 adopt a contact structure to generate vibration, which has little impact on the overall equipment, thereby improving the overall stability of the equipment and improving the comfort of the working environment. On the other hand, the first-level screening element is used to screen out oversized materials, and the second-level screening element is used to screen out undersized materials. The rotating arrangement of the second-level screening element 32 can use its centrifugal force to accelerate the output of materials, thereby improving the screening efficiency;
[0027] In the initial state, the lower contact block 35 can touch the upper contact block 34, so that the first-stage screening element 31 moves upward, and when the lower contact block 35 is separated from the upper contact block 34, it is reset under the elastic force and repeatedly rebounds under the elastic force to generate vibration, thereby realizing the screening of materials.
[0028] like Figure 2 , Figure 3 As shown, the screening mechanism 3 includes an elastic element 36 , and a mounting portion 24 is protruded from the inner wall of the housing 2 .

The bottom surface of the first guide tube 37 is fixedly connected to the primary screening element 31, and the top surface of the first guide tube 37 extends above the mounting portion 24 and is bent toward the housing 2 to form a folded edge 371. The first guide tube 37 surrounds the sieve hole of the primary screening element 31. In another embodiment, the primary screening element 31 is located above the mounting portion 24 without the need to arrange the first guide tube 37.
[0030] like Figure 2 , Figure 3 As shown, a rotation groove 25 is formed on the inner wall of the housing 2, and the secondary screening element 32 is rotatably arranged in the rotation groove 25, and the housing 2 and the secondary screening element 32 are rotatably connected.
[0031] The secondary screening element 32 has a connecting portion 321 on its bottom surface, and internal teeth are provided on the inner wall of the connecting portion 321. The output end of the driving element 33 has a gear matching the internal teeth on the connecting portion 321. The gear is meshed with the internal teeth of the connecting portion 321. The driving element 33 is a motor that drives the secondary screening element 32 to rotate.
[0032] like Figure 2 , Figure 3 As shown, the screening mechanism 3 includes a second connecting pipe 38, the bottom surface of the second connecting pipe 38 is fixedly connected to the shell 2, and the top surface of the second connecting pipe 38 extends to the secondary screening element 32, the third discharge port 23 and the sieve holes of the secondary screening element 32 are both located in the area surrounded by the second connecting pipe 38, and the second connecting pipe 38 can prevent materials from accumulating in the corners.
[0033] Conventional use: The material is screened twice by a vibrating primary screening element 32 and a rotating secondary screening element 33, thereby separating three specifications of the material.
[0034] For the rapid screening of medium-sized granular materials: The materials are first screened by the first-stage screening member 32. The medium-sized and small-sized granular materials fall onto the second-stage screening member 33. The small-sized granular materials fall through the sieve holes of the second-stage screening member 33. The medium-sized granular materials remain on the second-stage screening member 33 and are quickly diffused towards its outer periphery by the centrifugal force generated by the rotation of the second-stage screening member 33 until they are output from the second discharge port 22, thus completing the rapid screening of the medium-sized granular materials.
[0035] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention.
