[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1 - 4 , a sampling device for single coking coal, including a housing 1. A chute 3 is provided on the outer wall of one side of the housing 1. A fixed rod 9 is slidably connected in the chute 3. The chute 3 can guide the fixed rod 9 so that it can move up and down stably. A first spring 2 is welded to the top of the fixed rod 9, and the first spring 2 is fixed to the top of the chute 3. A round rod 4 is welded to the bottom end of the fixed rod 9. A first fixing block 6 is fixed to the bottom end of the round rod 4 by bolts. A support plate is fixed to the outer wall of one side of the housing 1 by bolts. A motor is fixed to the upper surface of the support plate by bolts. One end of the output shaft of the motor is key-connected to a second gear 8. A first gear 7 is rotatably connected to the outer wall of one side of the housing 1, and the first gear 7 meshes with the second gear 8. A connecting rod is welded to the outside of the first gear 7, and the connecting rod is slidably connected to the first fixing block 6. A sieve frame 10 is provided inside the housing 1, and both ends of the sieve frame 10 are fixed to the fixed rod 9. The coking coal entering the housing 1 falls onto the sieve frame 10, so that the coking coal with larger size moves out of the housing 1 along the inclined surface of the sieve frame 10, and the coking coal with smaller size falls downward through the sieve holes of the sieve frame 10. At the same time, the motor is started. The motor rotates to drive the second gear 8 to drive the first gear 7 to rotate, so that the connecting rod pulls the round rod 4 to move up and down along the fixed sleeve 5 through the first fixing block 6, and then the fixed rod 9 drives the sieve frame 10 to move up and down along the chute 3, and the first spring 2 contracts, so that the sieve frame 10 fully screens the coking coal. A sampling assembly is provided on the outer wall of one side of the housing 1.

[0025] In the present utility model, it should be noted that an L-shaped support frame 19 is fixed to the outer wall of one side of the housing 1 by bolts. Two guide rails 18 are fixed to the upper surface of the L-shaped support frame 19 by bolts. A collecting hopper 22 is slidably connected between the two guide rails 18. The guide rails 18 can guide the collecting hopper 22 to move stably, preventing it from tilting during movement and affecting the use effect of the device. A second fixing block 16 is fixed to the upper surface of the L-shaped support frame 19 by bolts. A guide rod 17 is fixed to one side of the second fixing block 16 by bolts, and the guide rod 17 is slidably connected to the collecting hopper 22. The guide rod 17 can further enable the collecting hopper 22 to move stably. A second spring 15 is sleeved on the outer side of the guide rod 17, and the two ends of the second spring 15 are respectively fixed to the second fixing block 16 and the collecting hopper 22. A material taking slot 21 is formed in one side of the housing 1. A panel 20 is rotatably connected to the top of the material taking slot 21, and the panel 20 can be in contact with the collecting hopper 22. Push the collecting hopper 22 to move inward along the guide rails 18. At this time, the collecting hopper 22 pushes the panel 20 to rotate and enters the housing 1 through the material taking slot 21, so that part of the coking coal on the conveyor belt in the housing 1 falls into the collecting hopper 22, and the second spring 15 stretches. After collection, release the collecting hopper 22, and the second spring 15 rebounds and stretches to reset the collecting hopper 22, thereby completing sampling. A fixed sleeve 5 is fixed to the outer wall of one side of the housing 1 by bolts, and the fixed sleeve 5 is slidably connected to the round rod 4. The fixed sleeve 5 can guide the round rod 4 to move stably. A first discharge port 11 is formed at the bottom of the housing 1. A second discharge port 12 is formed in the side surface of the middle part of the housing 1, and the second discharge port 12 is located on one side of the sieve frame 10. The coking coal with larger size on the sieve frame 10 moves out from the second discharge port 12 along the inclined surface of the sieve frame 10. A feeding port 14 is formed in the side surface of the top of the housing 1. The external conveyor belt transports coking coal and makes it fall downward into the housing 1 through the feeding port 14. A guide plate 13 is fixed to the lower part of the feeding port 14 by bolts, and the guide plate 13 is located above the sieve frame 10. The guide plate 13 can guide the coking coal to enter the sieve frame 10 along the inclined surface of the guide plate 13.

[0026] Working principle: When screening coking coal is required, first, the external conveyor belt transports the coking coal, causing it to fall downward through the feeding port 14 into the housing 1. Then, the coking coal moves downward along the inclined surface of the material guiding plate 13 and drops onto the screening frame 10. The coking coal with larger dimensions moves out along the inclined surface of the screening frame 10 from the second discharging port 12, and the coking coal with smaller dimensions drops downward through the screening holes of the screening frame 10. Meanwhile, the motor is started. The rotation of the motor causes the second gear 8 to drive the first gear 7 to rotate, so that the connecting rod pulls the round rod 4 to move up and down along the fixed sleeve 5 through the first fixing block 6. Furthermore, the fixed rod 9 drives the screening frame 10 to move up and down along the sliding groove 3, and the first spring 2 contracts. Thus, the screening frame 10 fully screens the coking coal. When sampling the coking coal is required, the collecting hopper 22 is pushed to move inward along the guide rail 18. At this time, the collecting hopper 22 pushes the panel 20 to rotate and enters the housing 1 through the material taking groove 21, causing part of the coking coal on the conveyor belt in the housing 1 to drop into the collecting hopper 22, and the second spring 15 extends. After the collection is completed, the collecting hopper 22 is released, and the second spring 15 rebounds and extends to reset the collecting hopper 22.
