[0036] Embodiment 1

[0037] As Figures 1 to 4 shown, a coal mining gravel sorting device includes a box body 1, a feeding port 2 is installed at the upper end of the box body 1, and coal mine gravel enters the inside of the box body 1 through the feeding port 2 for sorting. A mounting plate 3 is fixedly installed on the lower side of one end of the box body 1. There are two mounting plates 3 symmetrical about the box body 1. A rotatable screw rod 4 is installed at the upper end of one of the mounting plates 3, and a guide rod 5 is fixedly installed at the upper end of the other mounting plate 3. A motor 6 is provided at the upper end of the screw rod 4, and the motor 6 can drive the screw rod 4 to rotate.

[0038] One end of a lifting plate 7 is threadedly connected to the screw rod 4, and the other end of the lifting plate is slidably sleeved on the guide rod 5. The rotation of the screw rod 4 can drive the lifting plate 7 to move up and down. A pouring structure 8 is located at the upper end of the lifting plate 7. The pouring structure 8 includes a motor 13, and the motor 13 is installed at the upper end of the lifting plate 7. A worm 14 is installed at the rotating end of the motor 13, and the motor 13 can drive the worm 14 to rotate.

[0039] An adapter block 16 is fixedly installed on one side end of the lifting plate 7. A rotatable rotating shaft 17 is installed inside the adapter block 16. A worm gear 15 is installed at one end of the rotating shaft 17. The worm gear 15 is meshed with the worm 14. The rotation of the worm 14 can drive the worm gear 15 to rotate. A short plate 18 is fixedly installed on the rotating shaft 17. The two short plates 18 are located on both sides of the adapter block 16. The rotation of the worm gear 15 can drive the short plate 18 to rotate through the rotating shaft 17. A baffle 19 is installed at one end of the short plate 18, and a card slot 20 is installed at one end of the baffle 19. A discharge bucket 21 is installed inside the card slot 20. The rotation of the short plate 18 drives the discharge bucket 21 to rotate through the baffle 19 and the card slot 20. Coal mine gravel is placed inside the discharge bucket 21. When the lifting plate 7 moves up to the highest point, it drives the pouring structure 8 to move up. Thus, the rotation of the motor 13 drives the discharge bucket 21 to rotate, and the gravel can be poured into the feeding port 2. The baffle 18 can prevent the gravel from spilling. A buffer plate 32 is installed inside the feeding port 2, which can prevent the gravel from damaging the box body 1 due to too long falling time.

[0040] The sorting plate 9 is located inside the box body 1. There are two sorting plates 9, one above and the other below. One side of the box body 1 is equipped with two discharge openings 11. The two discharge openings 11 correspond to the two sorting plates 9 respectively. A sieve mesh 22 is installed inside the sorting plate 9. The aperture of the sieve mesh 22 located above is larger than that of the sieve mesh 22 located below. After the crushed stones are screened by the upper sieve mesh, the large-sized crushed stones remain on the sieve mesh 22, and the medium-sized and small-sized crushed stones move downward through the sieve mesh 22. Similarly, after being screened by the lower sieve mesh 22, the medium-sized crushed stones remain on the sieve mesh 22, and the small-sized crushed stones move downward into the box body 1. The large-sized and medium-sized crushed stones flow out through the discharge opening 11. The other adjacent side of the box body 1 is equipped with a discharge opening 12, and the small-sized crushed stones flow out through the discharge opening 12, so that crushed stones with three particle size ranges can be sorted.

[0041] Vibration structures 10 are installed at both ends of the sorting plate 9. The vibration structures 10 can drive the sorting plate 9 and the sieve mesh 22 to vibrate, thereby accelerating the screening process. The vibration structures 10 include an upper connecting plate 23 and a lower connecting plate 24. The upper connecting plate 23 and the lower connecting plate 24 are fixedly installed on the inner wall of the box body 1. A fixing rod 25 is installed between the upper connecting plate 23 and the lower connecting plate 24. The sorting plate 9 is slidably sleeved on the fixing rod 25. A spring 26 is sleeved on the fixing rod 25. A motor three 29 is fixedly installed at the outer end of the box body 1. The output end of the motor three 29 is connected to a rotating rod 28. The motor three 29 can drive the rotating rod 28 to rotate. A cam 27 is located at the lower end of the sorting plate 9. One end of the cam 27 is connected to the rotating rod 28. The rotating rod 28 drives the cam 27 to rotate, thereby driving the sorting plate 9 to slide up and down on the surface of the fixing rod 25. At the same time, the spring 26 is continuously stretched and compressed, causing the sorting plate 9 to vibrate. The vibration of the sieve mesh 22 can accelerate the screening of the crushed stones.

[0042] A dust suction pipe 30 is installed at the upper end of the box body 1. The other end of the dust suction pipe 30 is installed with a dust suction device 31. The dust suction device 31 sucks away the dust inside the box body 1 through the dust suction pipe 30, avoiding the dust from being scattered everywhere when the vibration structure 10 vibrates, which affects the air quality and the comfort of personnel.

[0043] Embodiment 2

The first motor 6 is started to drive the screw rod 4 to rotate, thereby driving the lifting plate 7 to move upward. After the lifting plate 7 moves upward to the highest point, the second motor 13 drives the worm 14 to rotate, thereby driving the worm gear 15 to rotate. The short plate 18 is driven to rotate through the rotating shaft 17. The rotation of the short plate 18 drives the feeding bucket 21 to rotate through the baffle plate 19 and the clamping groove 20, and the gravel can be poured into the feeding port 2. The third motor 29 drives the rotating rod 28 to rotate, and the rotating rod 28 drives the cam 27 to rotate, thereby driving the sorting plate 9 to slide up and down on the surface of the fixed rod 25. At the same time, the spring 26 is continuously stretched and compressed to make the sorting plate 9 vibrate. The two sets of sieve meshes 22 can screen the gravel into three different particle sizes of gravel, which flow out through the first discharge port 11 and the second discharge port 12 for sub-packaging.
