[0031] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the anti-clogging structure is arranged inside the cavity of the casing 20. The anti-clogging structure can prevent the sieve mesh 24 from being clogged during powder selection. The anti-clogging structure includes a powder selection cylinder 30, a feed pipe 31, a rotating roller 35 and a top ball 36. The powder selection cylinder 30 is fixedly connected to the top inside the cavity of the casing 20. The cavity inside the powder selection cylinder 30 is hollow. The sieve mesh 24 is fixedly connected inside the cavity of the powder selection cylinder 30. The feed pipe 31 is rotatably connected inside the cavity of the casing 20. The rotating roller 35 is rotatably connected to the wall surface of the feed pipe 31. The top ball 36 is fixedly connected to the wall surface of the rotating roller 35. The top ball 36 can contact the top of the sieve mesh 24.

[0032] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the powder selection cylinder 30 is in a hollow inverted conical shape, the air inlet cylinder 22 is in an L-shaped circular tube shape, the top of the air inlet cylinder 22 can communicate with the bottom inside the cavity of the powder selection cylinder 30, the lower half of the feed pipe 31 can penetrate through the top of the casing 20 and enter the cavity of the powder selection cylinder 30. The feed pipe 31 is in a circular tube shape. The rotating roller 35 is rotatably connected to the arc surface of the feed pipe 31. The rotating roller 35 is in a cylindrical shape. A plurality of same top balls 36 are evenly fixedly connected to the arc surface of the rotating roller 35. The top ball 36 is in a hemispherical shape. A plurality of top balls 36 are arranged in a circular array on the arc surface of the rotating roller 35. The size of the top ball 36 is the same as that of the sieve hole 25. The top ball 36 can enter the sieve hole 25. The anti-clogging structure further includes a driven wheel 32, a powder outlet pipe 33, a discharge pipe 34, a connecting plate 37 and a brush 38.

The discharge pipe 34 is fixedly connected to the bottom inside the cavity of the powder selection cylinder 30. The connecting plate 37 is fixedly connected to the arc surface of the feed pipe 31.

The powder outlet pipe 33 and the discharge pipe 34 are symmetrically arranged inside the cavity of the powder selection cylinder 30. The top of the brush 38 can contact the bottom of the sieve mesh 24;

[0033] During specific use, turn on the power supply and pour the material to be separated from the top opening of the feed pipe 31. When the power supply is turned on, the motor 26 can drive the driving wheel 27 to rotate on the top of the housing 20. The driving wheel 27 can drive the feed pipe 31 to rotate on the wall of the housing 20 through the teeth on the wall of the driven wheel 32 during rotation. The fan 23 can suck air into the cavity of the housing 20 from the circular groove opened on the wall of the housing 20 when the power supply is turned on, and then the air inlet cylinder 22 guides the air into the cavity of the powder separation cylinder 30. When the material enters the feed pipe 31, it will fall from the cavity of the feed pipe 31 into the cavity of the powder separation cylinder 30. At this time, the top of the air inlet cylinder 22 will blow the air upward, causing the powder in the material to move upward and pass through the sieve holes 25 on the wall of the sieve 24, and then be discharged from the powder outlet pipe 33 along with the wind direction. The un-screened material will move along the arc surface in the cavity of the powder separation cylinder 30 to the discharge pipe 34 at the bottom of the cavity of the powder separation cylinder 30, and then the material is discharged from the discharge pipe 34. When the feed pipe 31 rotates, it will drive the roller 35 and the top ball 36 to move simultaneously. The top ball 36 can roll along the top of the sieve 24 when driven by the feed pipe 31. The top ball 36 can enter the sieve holes 25 during rolling to push out the dust blocking the sieve holes 25. The connecting plate 37 can rotate simultaneously when the feed pipe 31 rotates. The connecting plate 37 can drive the brush 38 to clean the bottom of the sieve 24, and sweep off the dust accumulated at the bottom of the sieve 24;

[0034] In summary, by setting the anti-blocking structure, the dust blocking the sieve holes 25 can be automatically cleaned, and the bottom of the sieve 24 can be cleaned simultaneously. The anti-blocking structure drives the top ball 36 to automatically clean the sieve holes 25 and drives the brush 38 to automatically clean the bottom of the sieve 24 through the rotating feed pipe 31, thus effectively avoiding the problem of dust blocking the sieve holes 25 and reducing the working efficiency.

[0035] As Figure 2 、 Figure 4 and Figure 5 shown, an efficiency-enhancing structure is provided at the bottom of the feed pipe 31. The efficiency-enhancing structure includes connecting columns 40, a sub-cone 41, a guide cone 42, and guide plates 43. The connecting columns 40 are symmetrically and fixedly connected to the bottom of the feed pipe 31. The sub-cone 41 is fixedly connected to the bottom of the symmetric connecting columns 40. The guide cone 42 is fixedly connected to the bottom of the sub-cone 41. The guide plates 43 are also fixedly connected to the bottom of the sub-cone 41. The connecting columns 40 are cylindrical. The sub-cone 41 is conical. The guide cone 42 is inverted cylindrical. A plurality of guide plates 43 are uniformly arranged at the bottom of the sub-cone 41. The guide plates 43 are arc-shaped plates. The plurality of guide plates 43 are circularly arranged in an array at the bottom of the sub-cone 41. The guide cone 42 is located at the center of the bottom of the sub-cone 41;

[0036] During specific use, when the material enters the cavity of the classifier cylinder 30 from the feed pipe 31, it will first fall on the top inclined surface of the dividing cone 41, and then as the dividing cone 41 rotates, the material will be scattered in the cavity of the classifier cylinder 30. When the air inlet cylinder 22 discharges air, the rotating guide plate 43 will evenly guide the air towards the cavity of the classifier cylinder 30.

[0037] In summary, by setting the efficiency-enhancing structure, it is possible to prevent the material from clogging in the air inlet cylinder 22, and it is also possible to evenly blow the wind towards all the wall surfaces in the cavity of the classifier cylinder 30 when the air inlet cylinder 22 discharges air, thereby effectively improving the stability of the device during operation.

[0038] Working principle: Turn on the power supply and pour the material to be classified from the top opening of the feed pipe 31. When the power supply is turned on, the motor 26 can drive the driving wheel 27 to rotate on the top of the machine housing 20. The driving wheel 27 can drive the feed pipe 31 to rotate on the wall surface of the machine housing 20 through the teeth on the wall surface of the driven wheel 32 when rotating. The fan 23 can suck air into the cavity of the machine housing 20 from the circular groove opened on the wall surface of the machine housing 20 when the power supply is turned on, and then the air inlet cylinder 22 guides the air into the cavity of the classifier cylinder 30. When the material enters the feed pipe 31, it will fall from the cavity of the feed pipe 31 into the cavity of the classifier cylinder 30. At this time, the top of the air inlet cylinder 22 will blow the air upwards, causing the powder in the material to move upwards and pass through the sieve holes 25 on the wall surface of the sieve 24, and then be discharged from the powder discharge pipe 33 along with the wind direction. The unclassified material will move along the arc surface in the cavity of the classifier cylinder 30 to the discharge pipe 34 at the bottom of the cavity of the classifier cylinder 30, and then the material is discharged by the discharge pipe 34. When the feed pipe 31 rotates, it will drive the roller 35 and the top ball 36 to move simultaneously. The top ball 36 can roll along the top of the sieve 24 when driven by the feed pipe 31 to move. The top ball 36 can enter the sieve hole 25 when rolling and push out the dust blocking the sieve hole 25. The connecting plate 37 can rotate simultaneously when the feed pipe 31 rotates. The connecting plate 37 can drive the brush 38 to clean the bottom of the sieve 24 and sweep off the dust accumulated at the bottom of the sieve 24.
