As shown in fig. 4, a working area 201 is located between the two surrounding rollers 203, at this time, the working area 201 is completely located in the second area, the end of the left surrounding roller 203 is closer to the lowest point of the edge of the vibration disc 101, and the end of the right surrounding roller 203 is further away from the lowest point of the edge of the vibration disc 101, so that the material has a tendency to get close to the left surrounding roller 203 and get away from the right surrounding roller 203 after falling. When the vibration plate 101 rotates anticlockwise, the two surrounding baffle rollers 203 also rotate anticlockwise, and when the left surrounding baffle roller 203 rotates, materials contacted with the left surrounding baffle roller can be pushed to the right working area 201, so that all materials only move to the edge of the vibration plate 101 along the working area 201.

For example, the correspondence of the grade of diamond, the target grain size, and the second included angle is shown in the following table:

When the two fence rollers 203 synchronously rotate around the fixed shaft 202, the position of the working area 201 changes to change the moving speed of the material along the vibration disc 101, so as to adjust the target type-selecting granularity. Specifically, when the working area 201 is far away from the first plane, the moving speed of the material along the vibration disc 101 is larger, the target pattern selection granularity is larger, so that the material amount capable of completing pattern selection in unit time is improved, and when the working area 201 is close to the first plane, the moving speed of the material along the vibration disc 101 is smaller, the target pattern selection granularity is smaller, so that the material amount capable of completing pattern selection in unit time is reduced.

In use, the vibrator 218 causes the vibration disc 101 to vibrate, the material is fed to a first position in the working area 201, the first position is close to the center of the vibration disc 101, the material rolls downwards along the vibration disc 101 under the action of gravity and vibration, the end point of the rolling is the edge of the circular vibration disc 101, the distances between the edges of the circular vibration disc 101 and the feeding points are basically the same, and the distances and the time of the material moving on the vibration disc 101 are basically consistent, so that the probability of mixing the materials in different granularity ranges is reduced, the shape selection precision is improved, in addition, the output end of the motor 221 drives the first bevel gear 222 to rotate, the second bevel gear 223, the support cylinder 220 and the vibration disc 101 to rotate synchronously, namely, the circular vibration disc 101 can rotate continuously at a low speed, so that the abrasion degrees of different positions on the surface of the circular vibration disc 101 are basically consistent, the blocking effect on the movement of the material is reduced, and the shape selection efficiency is improved.
The two enclosing rollers 203 form a working area 201 on the surface of the vibration disc 101, and when the vibration disc 101 rotates around the fixed shaft 202, the two enclosing rollers 203 are driven to rotate in the same direction, wherein one enclosing roller 203 can push materials contacted with the two enclosing rollers to the working area 201, so that all the materials only move along the working area 201 to the edge of the vibration disc 101.
In the process of selecting the pattern, the accuracy of selecting the pattern can be adjusted by changing a first included angle formed by the two enclosing rollers 203, the target pattern selecting granularity can be adjusted by changing a second included angle formed by the vibration disc 101 and the horizontal plane, the position of the working area 201 can be changed by synchronously rotating the two enclosing rollers 203 around the fixed shaft 202, the position of the collecting bin 102 relative to the two enclosing rollers 203 can be correspondingly adjusted, so that the target pattern selecting granularity can be further adjusted, and in addition, the micro powder adhered to the surface of the vibration disc 101 is removed by auxiliary cleaning through the cleaning roller 224, so that the abrasion of abrasive particles is avoided, and the adhesion of the micro powder on the surface of the vibration disc 101 is aggravated.
