The support bars 11 and the cross bars 12 form a rectangular frame, and each support bar 11 The top of the screen is provided with a buffer spring 13, and the buffer spring 13 is arranged vertically along the vertical direction to prevent the screen box 2 from being affected by the vibration motor 3. The buffer spring 13 is used to support all the weight of the screen box 2, and the buffer spring 13 is 90 to the ground ° installation.

The sieve box 2 includes a box body 21 and a box cover 22. The box cover 22 is connected to the box body 21 by bolts to close the box body 21. The box body 21 is used to hold precious stones. The sieve box 2 is installed on the buffer spring 13 of the support frame 1 The whole screen box 2 is slightly inclined downward toward the side of the discharge end 24. The casing 21 is provided with a feed end 23 connected thereto. The feed end 23 is located at the high point of the screen box 2. In order to Make full use of the space in the screen box 2, the feeding end 23 is set near the outer wall of the screen box 2, the feeding end 23 can be a funnel-shaped feeding hopper; the discharging end 24 and the feeding end 23 are set oppositely , the discharge end 24 communicates with the screen box 2; the discharge end 24 is at the low point of the screen box 2, the discharge end 24 is set to three, the discharge end 24 includes a collection part 25 and a discharge port 26, and the collection part The inside of 25 is a hollow gem moving channel and communicates with the casing 21. The discharge port 26 is arranged on the collection part 25 and is positioned on the end away from the casing 21. The opening of the discharge port 26 is downward, and the collection part 25 is on the top. The middle and lower positions are arranged in layers, including the first collection part 251 located in the lower layer, the second collection part 252 located in the middle layer and the third collection part 253 located in the upper layer. The length of the third collection part 253 along the horizontal direction is smaller than that of the second collection part. The length of the part 252, the length of the second collecting part 252 is less than the length of the first collecting part 251, and the gemstone moving passage of the first collecting part 251 located in the lower layer is located on the same plane and connected with the inner bottom surface 27 of the box;

The box body 21 is provided with sieve plates arranged in layers in the upper and lower positions, and two layers of sieve plates arranged in layers and intervals along the vertical direction. The sieve plates are provided with sieve holes. The first sieve plate 28 of the first sieve plate 28, and the second sieve plate 29 located at the upper position in the box body 21, so that the second sieve plate 29 is located at the upper position of the first sieve plate 28, and the sieve holes on the second sieve plate 29 The diameter is greater than the sieve hole diameter on the first sieve plate 28, and the gemstone moving channel of the second collection part 252 at the middle position is located on the same plane and connected to the first sieve plate 28 at the middle position in the box body 21, The gem moving channel of the third collection part 253 on the upper layer is located on the same plane as the second sieve plate 29 on the upper layer and is connected.
