The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further details.
As shown in Figure 1, bearing steel ball type ball selecting machine of the present utility model comprises feed hopper, shell, upper conical sieve plate, the inferior pyramidal sieve plate, conical plate and motor, feed hopper is arranged on the top (center near cover top portion is good) of shell, upper conical sieve plate, the inferior pyramidal sieve plate, conical plate and motor are arranged on enclosure, the diameter of shell and upper conical sieve plate, the inferior pyramidal sieve plate, the size of conical plate is complementary, by upper, in, under order by upper conical sieve plate, inferior pyramidal sieve plate and conical plate are separately fixed in rotating shaft, rotating shaft is connected with motor by the angular wheel of its underpart, the top discharge mouth is set respectively on the sidewall of shell, middle discharging opening and lower discharge port, on, in, the position of lower discharge port respectively with upper conical sieve plate, the position of inferior pyramidal sieve plate and conical plate is corresponding, have equally distributed sieve aperture (as Fig. 3 on upper conical sieve plate and inferior pyramidal sieve plate, shown in 5), the screen-aperture size of upper conical sieve plate is identical with the size of standard steel ball, the screen-aperture of inferior pyramidal sieve plate is less than the diameter (can determine according to the lower limit of standard steel ball qualified size) of standard steel ball, for making steel ball have the sufficient time to screen the derivation that is conducive to again steel ball simultaneously on cone screen plate, the gradient of upper conical sieve plate is controlled at 1:(8～15) (gradient of the present utility model is the ratio calculating with height with the bottom surface radius of cone screen plate), the gradient of inferior pyramidal sieve plate is controlled at 1:(15～25), the gradient of conical plate have no special requirements (as 1:5～40), be respectively equipped with some curved baffles (as Fig. 2 on upper conical sieve plate and inferior pyramidal sieve plate, shown in 4), curved baffle is symmetrical along the central rotation of cone screen plate, curved baffle can outwards divide two rows to be arranged along symmetrical centre, every row is provided with 8～15, the arc length of curved baffle is generally 10～20cm, corresponding central angle is 30
o～150
o height 2～the 5cm of baffle plate, angle (if no special instructions, in the utility model, the angle of the string at other place and bus all defines with this) between the string of the curved baffle on upper and lower cone screen plate and the process cone screen plate bus of this curved baffle mid point remains on 20
o～60
