DETAILED DESCRIPTION

[0024] The technical scheme of the utility model will be further described below with reference to the drawings

[0025] As Figures 1-4 shown:

[0026] Embodiment 1: a mine machinery vibrating screen, including vibrating screen body 1, vibrating screen body 1 includes feed inlet 2, sieve frame 3, sieve net 4, discharge outlet 5, supporting seat 6, damping spring 7 and vibration motor 8, vibrating screen body 1 is equipped with dust falling mechanism, and the dust falling mechanism includes sliding assembly and spraying assembly;

[0027] Sliding assembly includes guide rod 9, and guide rod 9 is fixed to both sides of sieve frame 3 along the length direction of sieve frame 3 through fixing part, and a pair of guide holes 12 are arranged on the legs 11 of the left and right sides of sliding frame 10, and the guide rod 9 is arranged in the guide holes 12 of the legs 11 of the left and right sides of sliding frame 10, and sliding frame 10 can slide along guide rod 9 to different spraying positions, and the spraying area can be adjusted flexibly according to actual needs;

[0028] The screen frame 3 is equipped with a drive assembly, which includes a ball screw 13 and a rotary motor 14. The ball screw 13 is located on both sides of the screen frame 3 and below the guide rod 9, and is parallel to the guide rod 9. The output end of the rotary motor 14 is fixed to the end of the ball screw 13 near the feed inlet 2. Each of the support legs 11 on the left and right sides of the sliding frame 10 is provided with a screw hole 15, which is located below the guide hole 12. The ball screw 13 is threaded into the screw hole 15. The output end of the rotary motor 14 drives the ball screw 13 to rotate, and the ball screw 13 causes the body of the sliding frame 10 to slide along the guide rod 9. Thus, the position of the sliding frame 10 can be changed by driving the rotary motor 14. The rotary motor 14 can also be remotely controlled, making it more convenient to adjust the position of the sliding frame 10.

[0029] The spraying assembly includes a diverter pipe 16 and atomizing nozzles 17. The diverter pipe 16 is connected to the sliding frame 10 via a connecting mechanism. The connecting mechanism includes a T-shaped groove 20, which is opened on the sliding frame 10 along the thickness direction. The T-shaped groove 20 does not penetrate the sliding frame 10. A T-shaped block 19 is inserted into the T-shaped groove 20. The connecting block is rotatably connected to the diverter pipe 16. The T-shaped block 19 is dampedly rotatably connected to the diverter pipe 16. The diverter pipe 16 is provided with a water inlet 18 and multiple atomizing nozzles 17.

[0030] A support frame 27 is provided below the vibrating screen, and a support base 6 is fixedly connected to the support frame 27.

[0031] The method of using this utility model is as follows:

[0032] In use, the vibrating screen is started, and the ore is put into the screen frame 3. The vibrating motor 8 drives the vibrating screen body 1 to vibrate, thereby screening the ore. The shock-absorbing spring 7 can prevent the vibration from impacting the equipment itself and the surrounding environment. The T-shaped block 19 is inserted into the T-shaped groove 20. The rotary motor 14 on the ball screw 13 is turned on. The output end of the rotary motor 14 drives the ball screw 13 to rotate. The rotation of the ball screw 13 causes the sliding frame 10 to slide along the guide rod 9, thereby changing the spraying position of the spraying component. This allows for flexible adjustment of the spraying area according to actual needs. The external water source is connected to the water inlet 18 on the diversion pipe 16. The water flows into the diversion pipe 16 and is sprayed out through the atomizing nozzle 17. By rotating the diversion pipe 16, the spraying angle of the atomizing nozzle 17 can be adjusted, further improving the flexibility of dust suppression and cleaning. This effectively sprays water to suppress dust in the ore in the vibrating screen frame 3, reducing the dust generated during screening, improving the working environment, reducing the harm of dust to workers' health, and reducing environmental pollution.

[0033] Example 2: This example is basically the same as the previous example, except that a limiting mechanism is provided between the T-shaped groove 20 and the T-shaped block 19.

[0034] Specifically, the limiting mechanism includes a limiting groove 21, which is symmetrically arranged on the left and right sides of the T-shaped block 19. A receiving groove 22 is provided in the T-shaped groove 20, which is symmetrically arranged on the left and right sides of the inner edge of the T-shaped groove 20. A limiting block 23 is provided in the receiving groove 22. The surface of the limiting block 23 facing the insertion direction of the T-shaped block 19 is an inclined surface. A spring 26 is also provided in the receiving groove 22 to press the limiting block 23 against the central axis of the sliding frame 10. The limiting block 23 is engaged in the limiting groove 21.

[0035] The storage slot 22 has a toggle hole 24 on one side along the opening direction of the T-shaped slot 20, and a toggle rod 25 is provided on the limiting block 23. One end of the toggle rod 25 is fixedly connected to the limiting block 23, and the other end extends outward from the toggle hole 24 to the outside of the sliding frame 10.

[0036] As can be seen from the above, when the T-shaped block 19 is inserted into the T-shaped groove 20, the T-shaped block 19 presses against the inclined surface of the limiting block 23, so that the limiting block 23 is stored in the storage groove 22. At this time, the spring 26 is in a compressed state. When the limiting block 23 coincides with the limiting groove 21 in the T-shaped block 19, the spring 26 restores its deformation and pushes the limiting block 23 into the limiting groove 21, thereby fixing the spraying assembly on the sliding frame 10.

[0037] By moving the two levers 25, the levers 25 drive the limiting block 23 into the receiving groove 22, and the limiting block 23 disengages from the limiting groove 21 in the T-shaped block 19, thereby releasing the limit. At this time, the spraying component can be easily taken out, which improves the ease of use and maintenance efficiency of the equipment.
