[0024] A feeding mechanism is provided on the surface of the screening box 1, and the feeding mechanism includes a fixed block 2, which is fixedly connected to the surface of the screening box 1, and a first rotating rod 21 is movably connected to the inner side of the fixed block 2, and a rotating disk 22 is fixedly connected to the top of the first rotating rod 21, and a first connecting rod 24 is movably connected to the surface of the rotating disk 22, and a second connecting rod 25 is movably connected to the surface of the first connecting rod 24, and a movable groove 26 is provided on the inner side of the screening box 1. Through the rotation of the rotating disk 22, the rotating disk 22 can drive the first connecting rod 24 to move, and then the second connecting rod 25 moves accordingly to push and pull the hopper 11, so that the hopper 11 can reciprocate, and during the movement, the diamonds can fall evenly onto the screen plate 14, which can avoid the accumulation of diamonds on the screen plate 14, thereby improving the screening effect.
[0025] Furthermore, the feeding mechanism also includes a first motor 23, which is fixedly mounted on the bottom end of the fixed block 2, and the end of the first rotating rod 21 away from the turntable 22 is fixedly connected to the output end of the first motor 23. The surface of the hopper 11 is fixedly connected with a connecting block 27, and the inner wall of the movable groove 26 is provided with a sliding groove 28. Through the cooperation of the connecting block 27 and the sliding groove 28, the hopper 11 can be stably moved under the action of the second connecting rod 25, so that the movement of the hopper 11 can be limited.
[0026] Furthermore, the first connecting rod 24 is movably connected to the turntable 22 via a rotating shaft, one end of the second connecting rod 25 is movably connected to an end of the first connecting rod 24 away from the turntable 22 via a rotating shaft, and the other end of the second connecting rod 25 is movably connected to the hopper 11 via a rotating shaft. The hopper 11 is movably connected to the inner side of the movable groove 26.

[0028] The second motor 32 is fixedly mounted on the surface of the second rotating rod 3, and the second motor 32 is fixedly mounted on the surface of the second rotating rod 3.

The end of the slide rod 34 away from the slide groove 33 is fixedly connected with a fixed rod 35. The top of the fixed rod 35 is fixedly connected with a knocking block 36, and the surface of the slide rod 34 is fixedly connected with a second spring 37. Through the setting of the knocking block 36, when the cam 31 rotates and squeezes the fixed rod 35, the fixed rod 35 will drive the knocking block 36 to move vertically, and realize the knocking block 36 to knock on the bottom of the sieve plate 14. The knocking can reduce the blockage of diamonds in the sieve plate 14, so that the screening of large-particle diamonds is smoother.
[0029] Furthermore, the fixed rod 35 is movably connected to the slide groove 33 through the slide rod 34, one end of the second spring 37 is fixedly connected to the slide groove 33, and the other end of the slide rod 34 is fixedly connected to the slide rod 34. Through the setting of the second spring 37, when the cam 31 cancels the squeezing of the fixed rod 35, the fixed rod 35 can drive the knocking block 36 to reset under the rebound action of the second spring 37.
[0030] Working principle: When in use, the first motor 23 is electrically connected to an external power source, and the staff starts the first motor 23 by pressing the switch. The operation of the first motor 23 drives the first rotating rod 21 to rotate, and the turntable 22 rotates under the action of the first rotating rod 21. The first connecting rod 24 moves through the rotating shaft under the action of the turntable 22, and the second connecting rod 25 moves through the rotating shaft under the action of the first connecting rod 24, and pushes and pulls the hopper 11, so that the hopper 11 slides on the surface of the sliding groove 28 through the connecting block 27, and then the hopper 11 moves back and forth on the inner side of the movable groove 26, which can realize the uniform discharge of diamonds and facilitate the uniform distribution of the hopper 11 on the screen plate 14;
[0031] The second motor 32 is electrically connected to an external power source. The staff starts the second motor 32 by pressing the switch. The operation of the second motor 32 drives the second rotating rod 3 to rotate. The cam 31 will rotate accordingly under the action of the second rotating rod 3. When the cam 31 makes its convex surface face the fixed rod 35 during the rotation, it will squeeze the fixed rod 35, and then the fixed rod 35 will drive the knocking block 36 to rise under the action of the cam 31, so that the knocking block 36 knocks the sieve plate 14. At this time, the slide bar 34 will slide on the surface of the slide groove 33, and the second spring 37 will be in a contracted state. The knocking of the knocking block 36 facilitates the separation of the diamonds stuck in the holes of the sieve plate 14 from the holes, thereby avoiding the blockage of the sieve plate 14 and facilitating the faster discharge of the large-particle diamonds screened on the sieve plate 14; when the cam 31 makes its concave surface face the fixed rod 35 during the rotation, the slide bar 34 will reset under the rebound action of the second spring 37, and the fixed rod 35 drives the knocking block 36 to reset.
