[0024] Specifically, the body 1 is used to accommodate internal parts, the discharge hopper 2 is used to facilitate the placement of ore, the motor 3 is used to provide power, the driving gear 4 and the driven gear 5 are used for meshing transmission, the rotating rod 7 is used to transmit motion and support the crushing barrel 6, and the motor 3 is used to drive the driving gear 4 to rotate, thereby meshing with the driven gear 5.

[0025] With corresponding rotation, the two crushing drums 6 rotate simultaneously to crush the coal blocks. The collecting box 17 is used to collect the coal blocks. The collecting box 17 is slidably connected in the two mounting seats 13. The insert rod 16 is inserted into the mounting seat 13 and the collecting box 17 so that the collecting box 17 can be quickly disassembled and installed.

[0026] Reference Figure 1 and Figure 3 The screening assembly includes a motor 8, which is fixedly connected to the left side of the machine body 1. The left and right ends of the motor 8 are fixedly connected to a transmission shaft 9. The ends of the two transmission shafts 9 that are far away are fixedly connected to a rotating wheel 10. The two rotating wheels 10 are rotatably connected to a driving rod 12 on the far side. The ends of the two driving rods 12 that are away from the rotating wheel 10 are rotatably connected to a supporting block 14. The tops of the two supporting blocks 14 are fixedly connected to a sieve plate 18. The front and rear sides of the two mounting seats 13 are rotatably connected to a swing arm 15. The swing One end of the arm 15 away from the mounting seat 13 is rotatably connected to one side of the sieve plate 18, both ends of the driving rod 12 are fixedly connected with a rotating shaft 11, the driving rod 12 is rotatably connected to the rotating wheel 10 through one of the rotating shafts 11, and the driving rod 12 is rotatably connected to the support block 14 through another rotating shaft 11, and the upper and lower ends of the swing arm 15 are fixedly connected with a rotating shaft 2 19, the swing arm 15 is rotatably connected to the mounting seat 13 through one of the rotating shafts 2 19, and the swing arm 15 is rotatably connected to the sieve plate 18 through another rotating shaft 2 19.

[0027] Specifically, the motor 2 8 is a bidirectional output motor, with a transmission shaft 9 and a rotating wheel 10 fixed at the left and right ends, a rotating shaft 11 fixed at the edge of the rotating wheel 10 to achieve an eccentric wheel structure, a driving rod 12 is sleeved on the outer periphery of the rotating shaft 11, and the other end is connected to a support block 14, and a sieve plate 18 is fixed on the top of the support block 14.

[0028] Working principle: First, start motor 1 3, which makes the driving gear 4 rotate, and the driving gear 4 meshes with the driven gear 5 for transmission, and the two crushing barrels 6 rotate at the same time to crush the coal blocks. Then, start motor 2 8, which drives the wheels 10 on both sides to rotate at the same speed, so that the two driving rods 12 make circular motions accordingly. When the driving rod 12 makes circular motions, the other end of the driving rod 12 drives the screen to reciprocate through the supporting block 14, and the swing arm 15 supports the screen plate 18, and cooperates with the driving rod 12 to make the screen plate 18 reciprocate, so that the coal blocks dropped on the screen plate 18 are vibrated and screened, and the larger coal blocks remain on the screen plate 18 for the next crushing, while the smaller coal blocks fall into the collection box 17 for collection.
