More specifically, as shown in fig. 1, the first fan 41 is located at the rightmost side of the first sorting chamber 12, and at this time, the light materials are discharged from the first discharge port 31 located at the leftmost side of the first sorting chamber 12 under the sorting blowing force of the first fan 41; in the embodiment, the distance between the fan and the material is far, the blowing force on the material is small, and the sorting effect on the material with small quality is good. Further, as shown in fig. 2, the first fan 41 is located near the material inlet 21 to form a separation suction, and the material impurities are discharged from the first material outlet 31 under the separation suction of the first fan 41. In the embodiment of the invention, the first fan 41 forms a separation suction force, and the suction force is softer, so that the separation of materials with less quality difference between some material particles and sundries can be realized.

It should be understood that the second fan 42 is arranged in a similar manner to the first fan 41. The specific position of the second fan 42 can be adjusted according to the actual situation, which is not required by the embodiment of the invention, and the specific position of the second fan 42 can be adjusted according to the type of the material when the separator works, so that the working performance of the separator is more stable, the separation effect is more obvious, and the service lives of the first fan 41 and the second fan 42 are prolonged. And the sorting blowing force or suction force of the first fan 41 and the second fan 42 is facilitated, so that the power loss in the working process is small, and the energy is saved.

When the mass of the material is small, the first fan 41 can be moved to a position far away from the material, so that the phenomenon that grains and sundries are discharged simultaneously due to excessive wind force can be avoided. When the material sundries remain at the bottom of the sorting chamber, the fan can be downwards adjusted through the connecting rod, so that the cleaning effect on the sorting chamber is realized. Further, the second fan 42 is disposed in a similar manner to the first fan 41, and will not be described herein.

Further, the second fan 42 is similar to the first fan 41, and will not be described herein.
