Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a coal and soil transfer and transportation anti-blocking device. Background Technology

[0002] In open-pit coal mines, during the processes of stripping, loading, transportation, and unloading, large quantities of coal and soil materials need to be transferred from mine trucks to conveyor belts, hoppers, or temporary storage areas via a transfer process. This process is usually accompanied by high-speed material falling, impacting, and rebounding. Because the coal and soil mixture is prone to forming "arch bridges" or "hanging materials" in the discharge chamber, material accumulation or even blockage can occur, affecting normal unloading.

[0003] Chinese patent CN117722693A discloses a coal chute anti-clogging device. It uses a vibration mechanism to apply different vibration amplitudes depending on the degree of clogging, thereby shaking off coal slag adhering to the inner wall of the chute. A scraping component can also scrape off the coal slag from the inner wall of the chute. However, the overall structure of this patent is complex, and its reliability is poor in harsh environments such as low temperatures, high dust levels, and high humidity. Utility Model Content

[0004] This utility model provides a coal and soil transfer and transportation anti-blocking device, which has a simple structure, high reliability, and can effectively prevent material blockage.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, a coal and soil transfer and anti-blocking device of one embodiment includes a guide hopper 1, a guide cone 2, and a cable 3. The guide hopper 1 is formed by multiple guide plates 11. The guide plates 11 are trapezoidal, which makes the inner wall of the guide hopper 1 inclined. The upper opening area of ​​the guide hopper 1 is larger than the lower opening area. The guide cone 2 is suspended inside the guide hopper 1. One end of the cable 3 is connected to the guide cone 2, and the other end of the cable 3 is connected to the guide plate 11.

[0021] When material falling into the guide hopper 1 impacts the guide cone 2, the guide cone 2 disperses the material. The cable 3 between the guide cone 2 and the guide plate 11 pulls on the guide cone 2 to prevent it from falling, and also cuts and disperses the material, further reducing the risk of blockage. This utility model's coal and soil transfer and transportation anti-blockage device has a simple structure, requires no motor or power supply, has high reliability, and can adapt to harsh outdoor environments.

[0022] like Figure 2 As shown, the guide cone 2 is an octahedron, comprising an upper square pyramid 21 and a lower square pyramid 22. The four vertices of the guide cone 2 lie on the same plane, and the line connecting the other two vertices coincides with the vertical direction. Material falling onto the guide cone 2 is first dispersed by the pointed tip of the upper square pyramid 21. The surface of the upper square pyramid 21 is inclined, making it difficult for material to adhere to the surface of the guide cone 2. To improve the wear resistance of the guide cone 2, its surface can be made of silicon nitride ceramic material. The lower square pyramid 22 is not directly impacted by the material; its function is to lower the center of gravity of the guide cone 2. The weight of the lower square pyramid 22 is greater than that of the upper square pyramid 21, making the guide cone 2 more stable under the impact of the material.

[0023] like Figure 1 As shown, one end of the cable 3 is connected to the four vertices of the guide cone 2 on the same plane, so that the guide cone 2 is subjected to a relatively uniform tension in four directions, which is beneficial to maintaining the stability of the guide cone 2.

[0024] like Figure 3 As shown, the top of the guide plate 11 is provided with a first receiving cavity 100. Inside the first receiving cavity 100, there is a fixed pulley 4 and a tension spring 5. One end of the cable 3 passes through the inside of the first receiving cavity 100, and the cable 3 passes around the fixed pulley 4 and is connected to one end of the tension spring 5. The fixed pulley 4 can adjust the direction of the cable 3 so that the length direction of the tension spring 5 is consistent with the extension direction of the cable 3, so as to better exert the function of the tension spring 5.

[0025] When the guide cone 2 is impacted by material, if the other end of the cable 3 is directly connected to the surface of the guide plate 11, both ends of the cable 3 will be repeatedly pulled. After prolonged use, this can easily cause the cable 3 to break and damage the guide cone 2 or the guide plate 11. Therefore, in this embodiment, one end of the cable 3 is connected to the tension spring 5, so that the cable 3 can provide a certain degree of cushioning, making it less likely to break, and also providing a certain degree of protection for the guide cone 2 and the guide plate 11.

[0026] Of course, in order to maintain the posture of the guide cone 2, the tension spring 5 cannot be too soft, to prevent the cable 3 from overstretching and causing the guide cone 2 to roll over.

[0027] like Figure 4 and Figure 5As shown, the surface of the guide plate 11 has a first through hole 200, and a sealing element 6 is installed inside the first through hole 200. The pull cable 3 passes through the sealing element 6. If a large amount of material enters the interior of the first receiving cavity 100, the fixed pulley 4 and the tension spring 5 will not function properly, so the sealing element 6 is required for sealing. In addition, when the pull cable 3 passes through the sealing element 6, the sealing element 6 can also scrape off any material that may be attached to the surface of the pull cable 3, thus cleaning the pull cable 3 and preventing the pull cable 3 from carrying material into the interior of the first receiving cavity 100. In order to reduce the material attached to the surface of the pull cable 3 and to ensure good sealing performance, the surface of the pull cable 3 is polished to ensure a smooth surface. The sealing element 6 is made of an elastic material with a low coefficient of friction with the pull cable 3 to prevent the pull cable 3 from getting stuck.

[0028] like Figure 5 As shown, the sealing element 6 includes a first limiting plate 61, a connecting portion 63, and a second limiting plate 62. The diameters of both the first limiting plate 61 and the second limiting plate 62 are larger than the diameter of the connecting portion 63. The first limiting plate 61 and the second limiting plate 62 are respectively disposed at both ends of the connecting portion 63, which is disposed within the first through hole 200. The first limiting plate 61 is disposed on the inner surface of the guide plate 11, and the second limiting plate 62 is disposed inside the first receiving cavity 100. The sealing element 6 is fixed to the guide plate 11 by the first limiting plate 61 and the second limiting plate 62. The first limiting plate 61, by covering the first through hole 200, can prevent external materials from entering the interior of the first receiving cavity 100.

[0029] like Figures 3 to 5 As shown, the sealing element 6 is inclined towards the guide cone 2, and the height of the second limiting plate 62 is higher than that of the first limiting plate 61. The inclined arrangement of the sealing element 6 can prevent the material from directly impacting the surface of the sealing element 6, thus extending its service life. On the other hand, it also matches the direction of the cable 3, preventing the cable 3 from bending significantly when entering the first receiving cavity 100 and preventing the cable 3 from getting stuck during movement.

[0030] like Figure 4 and Figure 5 As shown, the guide plate 11 also has a second receiving cavity 300 inside, and a counterweight 7 is slidably disposed in the second receiving cavity 300. The end of the tension spring 5 away from the cable 3 is connected to the counterweight 7. A second through hole 400 is provided between the first receiving cavity 100 and the second receiving cavity 300, through which the tension spring 5 can pass. The counterweight 7 can slide in the second receiving cavity 300. When the guide cone 2 is not impacted by material, the counterweight 7 will move up a certain distance. The counterweight 7 has a large weight and a short stroke. When used with the tension spring 5, it can provide a better cushioning effect. like Figure 6As shown, the inner wall of the guide plate 11 is provided with a guide plate 8 and an elastic support member 9. One end of the guide plate 8 is hinged to the guide plate 11, and the elastic support member 9 is disposed between the guide plate 8 and the guide plate 11. One end of the elastic support member 9 is hinged to the guide plate 11, and the other end of the elastic support member 9 is slidably connected to the side of the guide plate 8 facing the guide plate 11. When the material falls on the surface of the guide plate 8, the resulting impact will cause the guide plate 8 to move closer to the guide plate 11. As the material gradually slides off the surface of the guide plate 8, the guide plate 8 bounces up under the action of the elastic support member 9, thereby providing a certain degree of patting effect on the material, better dispersing the material, and preventing the material from clogging inside the guide hopper 1. To avoid interference between the elastic support member 9 and the guide plate 8, a groove 500 is provided on the side of the guide plate 8 near the guide plate 11 to accommodate the elastic support member 9.

[0031] like Figure 7 and Figure 8 As shown, the elastic support 9 includes a sleeve 91, a support rod 92, a spring 93, and a connecting post 94. One end of the sleeve 91 is hinged to the guide plate 11. The spring 93 is disposed inside the sleeve 91. One end of the support rod 92 is inserted into the sleeve 91. The connecting post 94 is disposed at the other end of the support rod 92 and is slidably connected to the guide plate 8. Using the spring 93, the elastic support 9 can extend and retract. When not impacted by material, the guide plate 8 is in an extended state. When impacted by material, the spring 93 is compressed, the support rod 92 is pressed into the sleeve 91, the length of the elastic support 9 shortens, and the guide plate 8 moves closer to the surface of the guide plate 11.

[0032] Specifically, the groove 500 has a sliding groove 600 on its wall, and the connecting column 94 is slidably disposed in the sliding groove 600. Since the elastic support 9 not only needs to rotate, but its length also changes, the elastic support 9 is slidably connected to the guide plate 8 rather than being fixedly connected, which enables the elastic support 9 to work normally.

[0033] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
