Detailed Description of the Preferred Embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0026] Refer to Figures 1-5, the utility model provides a crushing and sampling device for open-pit coal mining, which includes a cylinder body 1 with an open top. A top cover 2 is detachably connected to the top opening of the cylinder body 1. An oil cylinder 3 is arranged on the top cover 2, and the output end of the oil cylinder 3 is fixedly connected with a crushing head 4. A support seat 6 with a first groove 5 is fixedly connected to the inner bottom of the cylinder body 1. The first groove 5 is used to place a bottom shell 7, and the inner cavity of the bottom shell 7 is used to place a filter shell 8. A plurality of knocking components are arranged between the filter shell 8 and the inner side wall of the cylinder body 1, and the crushing head 4 is located directly above the filter shell 8;

[0027] A plurality of second grooves 9 are formed on the top surface of the bottom shell 7, and a first spring telescopic rod 10 is fixedly connected in the second grooves 9. The output end of the first spring telescopic rod 10 extends out of the second grooves 9, and a plurality of connecting rods 11 are fixedly connected to the top surface of the bottom shell 7;

[0028] A connecting ring 12 is fixedly connected to the circumferential direction of the top surface of the filter shell 8. A plurality of through holes 13 for the plurality of connecting rods 11 to pass through one by one are formed on the connecting ring 12, and the bottom surface of the connecting ring 12 is used to abut against the output ends of the plurality of first spring telescopic rods 10;

[0029] A plurality of pressing rods 14 are fixedly connected to the top cover 2, and the ends of the plurality of pressing rods 14 far away from the top cover 2 are used to abut against the top surface of the connecting ring 12.

[0030] By placing the bottom shell 7 into the first groove 5, passing the connecting rods 11 through the through holes 13, and making the output ends of the plurality of first spring telescopic rods 10 abut against the bottom surface of the connecting ring 12, the connecting ring 12 and the filter shell 8 are located above the bottom shell 7. Then, by uniaxially mounting the top cover 2 on the cylinder body 1, the connecting ring 12 is pressed down by the pressing rods 14 to compress the first spring telescopic rods 10, so that the filter shell 8 is located in the inner cavity of the bottom shell 7. Thus, the ore in the filter shell 8 is crushed by driving the crushing head 4 through the oil cylinder 3. After the crushing is completed, the top cover 2 is removed, and the first spring telescopic rods 10 automatically lift the filter shell 8, separating the filter shell 8 from the bottom shell 7. And while the filter shell 8 is moving, the knocking parts knock the filter shell 8, effectively separating the ore fragments from the powder, so that the ore fragments are located in the filter shell 8 and the ore powder is located in the bottom shell 7, eliminating the step of manually separating the ore fragments from the powder, reducing the labor intensity of the operators, and improving the crushing and sampling efficiency of the operators during the detection process.

[0031] When it is necessary to take out the ore at the crushing port, the connecting rod 11 can be directly pulled, so as to take out the bottom shell 7 and the filter shell 8 from the cylinder body 1 at the same time, and then slide the connecting ring 12 until the through hole 13 is disengaged from the connecting rod 11, and the filter shell 8 is removed.

[0032] Further optimized solution: The knocking component includes a connecting frame 15. The connecting frame 15 is arranged on the side wall of the connecting ring 12. A shaft rod 16 is rotatably fitted on the connecting frame 15. A rotating wheel 17 is fixedly connected to the shaft rod 16. The rotating wheel 17 is used to abut against the inner side wall of the cylinder body 1. A plurality of second spring telescopic rods 18 are fixedly connected to the shaft rod 16. The output end of the second spring telescopic rod 18 is fixedly connected with an oval knocking head 19. A plurality of support rods 20 are arranged on both sides of the connecting frame 15. The support rods 20 are fixedly connected with the connecting ring 12. An oval force-receiving head 21 is fixedly connected to the support rods 20. The plurality of knocking heads 19 correspond to the plurality of force-receiving heads 21 one by one.

[0033] During the process of installing or removing the cylinder body 1 on the connecting ring 12 and the filter housing 8, the rotating wheel 17 is in a state of abutting against the inner side wall of the cylinder body 1. Thus, when the connecting ring 12 moves, the rotating wheel 17 rotates accordingly, and then the shaft rod 16 rotates. By the rotation of the shaft rod 16, the second spring telescopic rods 18 and the knocking heads 19 are driven to rotate. Furthermore, through the cooperation of the oval knocking heads 19, the oval force-receiving heads 21 and the second spring telescopic rods 18, the knocking heads 19 continuously knock the force-receiving heads 21. Then, the vibration generated by the force-receiving heads 21 is transmitted to the connecting ring 12 through the support rods 20, and then transmitted from the connecting ring 12 to the filter housing 8, improving the separation effect of the ore powder and fragments.

[0034] Further optimized solution: The connecting frame 15 is fixedly connected with the connecting ring 12 through a plurality of third spring telescopic rods 22. The third spring telescopic rods 22 can improve the contact effect between the rotating wheel 17 and the inner side wall of the cylinder body 1.

[0035] Further optimized solution: A pair of first ear plates 23 are fixedly connected to the outer side wall of the top end of the cylinder body 1. A pair of second ear plates 24 are fixedly connected to the outer side wall of the top cover 2. The pair of second ear plates 24 and the pair of first ear plates 23 are detachably connected by bolts.

[0036] Further optimized solution: The first groove 5, the bottom shell 7 and the filter housing 8 are hemispherical structures that are stacked in sequence and have matching structures. The hemispherical structure is not only convenient for stacking. After stacking, the bottom shell 7 fits with the first groove 5, and the filter housing 8 fits with the inner cavity of the bottom shell 7, so that the bottom shell 7 supports the filter housing 8, preventing the filter housing 8 from deforming when the crushing head 4 is driven by the oil cylinder 3.

[0037] Further optimized solution: The outer shell and the output end of the oil cylinder 3 are respectively located on both sides of the top cover 2, reducing the size of the overall structure and effectively improving the space utilization rate inside the cylinder body 1.

[0038] Further optimized solution: A plurality of third grooves 25 are formed on the top surface of the connecting ring 12. The plurality of pressing rods 14 correspond to the plurality of third grooves 25 one by one. The third grooves 25 are used for the pressing rods 14 to insert. After the third grooves 25 and the pressing rods 14 abut against each other, the limiting effect on the connecting ring 12 can be improved.

[0039] For a further optimized solution, a plurality of bottom frames 26 are fixedly connected to the top cover 2, and counterweights are placed in the bottom frames 26 to facilitate the downward pressing of the top cover 2 on the filter housing 8, so that the first spring telescopic rod 10 is stressed, and the filter housing 8 effectively fits with the inner cavity of the bottom shell 7.
