Description

Technical Field

[0001] This application belongs to the field of coal mine coal gangue separation technology, specifically a double-layer belt coal gangue separation and screening device for mines. Background Technology

[0002] A coal mine gangue separation and screening device is a specialized piece of equipment used in coal mine production to separate coal from gangue. It is of great significance for improving coal quality, reducing transportation costs, and protecting the environment. This device effectively separates gangue from coal in raw coal through physical screening, ensuring the full utilization of coal resources.

[0003] For example, application CN218223335U discloses a coal and gangue separation mechanism for a mining belt conveyor, including a mounting base, a limiting plate, and a connecting plate. Hinged seats are fixed at both ends of one side of the mounting base, and adjusting mechanisms are installed on both sides of the mounting base away from the hinged seats. This utility model, by setting a screening structure, places the partition plate at the top of the limiting plate according to the degree of coal crushing, so that both ends of the locking plate are placed inside the limiting groove. Under the action of the limiting block, the locking plate is prevented from sliding out of the limiting groove. Through the interaction between the locking plate and the limiting groove, the spacing between adjacent partition plates can be adjusted. The main cross-section of the partition plate is triangular, allowing gangue to slide down from the end of the partition plate away from the guide seat, and coal to fall between the partition plates. This realizes the function of easily adjusting the spacing between the partition plates, thereby improving the applicability of the coal and gangue separation mechanism for the mining belt conveyor in use.

[0004] However, during the implementation of the application, it was found that the regulating mechanism was not equipped with anti-fall devices on both sides. During the falling process, the coal and gangue may splash to the side due to the impact, which would affect the efficiency of the overall separation process and the cleanliness of the ground. Utility Model Content

[0005] The purpose of this application is to provide a double-layer belt conveyor coal and gangue separation and screening device for mines in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A double-layer belt coal and gangue separation and screening device for mines includes a mounting base. An angle adjustment device is provided on one side of the upper surface of the mounting base. A partition plate mounting base is provided on the top of the angle adjustment device. A mounting column is provided on the side of the upper surface of the mounting base opposite to the angle adjustment device. A rotating disk is rotatably provided at the top of the mounting column. The top of the rotating disk is connected to the lower surface of the partition plate mounting base. Foldable and flip-up protective plate mounting bases are provided on both sides of the mounting base. Protective baffles are fixedly installed on the outer surface of the protective plate mounting bases.

[0007] By adopting the above technical solution, when using the device, after fixing it with the mounting base, the angle adjustment device is used to adjust the partition plate mounting slot to a suitable angle. Then, the protective plate mounting base and protective baffle are flipped upwards, and the protective plate mounting base is fixed with the bottom protective plate positioning bolts. During the process of coal and gangue falling, even if splashing occurs, it will be bounced back to the surface of the partition plate body by the blocking effect of the protective baffle, thereby preventing coal and gangue from falling as much as possible, improving the overall separation efficiency, and also ensuring the cleanliness of the ground.

[0008] As a further description of the above technical solution, side mounting rods are fixedly installed on both sides of the mounting base, and an inner rotating shaft is fixedly installed between the side mounting rods. A protective plate mounting base is rotatably provided on the outside of the inner rotating shaft.

[0009] By adopting the above technical solution, the protective plate mounting base can be rotated and folded up, and can be lowered when not in use, reducing space occupation.

[0010] As a further description of the above technical solution, the upper surface of the partition plate mounting chassis is provided with a plurality of partition plate mounting slots, and the partition plate body is inserted into the interior of the partition plate mounting slots.

[0011] By adopting the above technical solution, the spacing between the partition plates can be adjusted by inserting the partition plate body into different partition plate mounting slots, thereby increasing the adjustability during the overall use process.

[0012] As a further description of the above technical solution, the upper surface of the mounting base is provided with a plurality of guide plate mounting slots near the angle adjustment device. The guide plate mounting slots are provided with guide plate bodies inside, and the highest point of the guide plate body and the highest point of the partition plate body are located in the same horizontal plane.

[0013] By adopting the above technical solution, the gangue slides from the end of the separator plate away from the guide plate onto the gangue conveyor belt, and then the coal falls from between the separator plates onto the coal conveyor belt, thus facilitating the separation of gangue and coal.

[0014] As a further description of the above technical solution, a plurality of guide plate mounting strips are fixedly installed at the bottom end of the guide plate body, and a guide plate fixing threaded rod is threadedly connected to the front end of the mounting base and the guide plate mounting strip through a threaded hole. The guide plate fixing threaded rod passes through the mounting base and is threadedly connected inside the guide plate mounting strip.

[0015] By adopting the above technical solution, the guide plate body can be disassembled and installed, increasing the convenience of use.

[0016] As a further description of the above technical solution, a detachable wear-resistant rubber plate is provided on the top of the guide plate body, and a rubber plate mounting bolt is threadedly connected to the side surface of the guide plate body near the mounting base.

[0017] By adopting the above technical solution, the wear-resistant rubber plate on the top of the guide plate body will experience significant wear after prolonged use. Therefore, by replacing the individual wear-resistant rubber plates, the separation efficiency of the entire device will not be affected, thus ensuring the overall separation efficiency and reducing operating costs.

[0018] As a further description of the above technical solution, multiple reinforcing crossbars are fixedly installed between the mounting bases, and multiple base fixing holes are opened on the surfaces of the mounting bases and the reinforcing crossbars.

[0019] By adopting the above technical solution, it is convenient to fix the mounting base.

[0020] As a further description of the above technical solution, the bottom of the protective plate mounting base is threaded with a plurality of protective plate positioning bolts, which penetrate the protective plate mounting base and are connected to the surface of the inner rotating shaft.

[0021] By adopting the above technical solution, the mounting base of the protective plate can be locked and fixed, increasing its stability during use.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] 1. In this application, when using the device, after fixing it with the mounting base, the angle adjustment device is used to adjust the partition plate mounting slot to a suitable angle. Then, the protective plate mounting base and the protective baffle are flipped upwards, and the protective plate mounting base is fixed with the protective plate positioning bolts at the bottom. Afterwards, during the process of coal and gangue falling, even if splashing occurs, it will be bounced back to the surface of the partition plate body by the blocking effect of the protective baffle, thereby preventing coal and gangue from falling as much as possible, improving the overall separation efficiency, and also ensuring the cleanliness of the ground.

[0024] 2. In this application, after prolonged use, the wear-resistant rubber plate above the guide plate body will experience significant wear. Therefore, by replacing the individual wear-resistant rubber plates, the separation efficiency of the entire device will not be affected, thus ensuring the overall separation efficiency and reducing the cost of use.

[0034] Reference Figure 1-5 ,

[0035] A double-layer belt conveyor coal and gangue separation and screening device for mines includes a mounting base 1. An angle adjustment device 3 is provided on one side of the upper surface of the mounting base 1. A partition plate mounting base 2 is provided on the top of the angle adjustment device 3. A mounting column 13 is provided on the side of the upper surface of the mounting base 1 opposite to the angle adjustment device 3. A rotating disk 14 is rotatably mounted on the top of the mounting column 13. The top of the rotating disk 14 is connected to the lower surface of the partition plate mounting base 2. Foldable and flip-up protective plate mounting bases 6 are provided on both sides of the mounting base 1. A protective plate mounting base 6 is fixedly mounted on the outer surface of the protective plate mounting base 6. When using the protective baffle 7, after fixing the device with the mounting base 1, the angle adjustment device 3 is used to adjust the partition plate mounting slot 11 to a suitable angle. Then, the protective plate mounting base 6 and the protective baffle 7 are flipped upwards, and the protective plate mounting base 6 is fixed with the protective plate positioning bolts 20 at the bottom. Afterwards, during the process of coal and gangue falling, even if splashing occurs, it will be bounced back to the surface of the partition plate body 12 by the blocking effect of the protective baffle 7, thereby preventing coal and gangue from falling as much as possible, improving the overall separation efficiency, and also ensuring the cleanliness of the ground.

[0036] Side mounting rods 4 are fixedly installed on both sides of the mounting base 1. An inner rotating shaft 5 is fixedly installed between the side mounting rods 4. A protective plate mounting base 6 is rotatably mounted on the outside of the inner rotating shaft 5. The protective plate mounting base 6 can be rotated and retracted. When not in use, the protective plate mounting base 6 can be lowered to reduce space occupation.

[0037] The upper surface of the partition plate mounting chassis 2 is provided with multiple partition plate mounting slots 11. Partition plate bodies 12 are inserted into the partition plate mounting slots 11. By inserting the partition plate bodies 12 into different partition plate mounting slots 11, the spacing between the partition plate bodies 12 can be adjusted, thereby increasing the adjustability during the overall use.

[0038] Multiple guide plate mounting slots 8 are provided on the upper surface of the mounting base 1 near the angle adjustment device 3. The guide plate mounting slots 8 are equipped with guide plate bodies 15, and the highest point of the guide plate body 15 is on the same horizontal plane as the highest point of the partition plate body 12. This allows the gangue to slide from the end of the partition plate body 12 away from the guide plate body 15 onto the gangue conveyor belt. Then, the coal falls from between the partition plate bodies 12 onto the coal conveyor belt, thus facilitating the separation of gangue and coal.

[0039] Multiple guide plate mounting strips 18 are fixedly installed at the bottom of the guide plate body 15. The front end of the mounting base 1 is threadedly connected to the guide plate mounting strip 18 through a threaded hole. The guide plate fixing threaded rod 9 passes through the mounting base 1 and is threaded inside the guide plate mounting strip 18, so that the guide plate body 15 can be disassembled and installed, increasing the convenience of use.

[0040] A removable wear-resistant rubber plate 16 is provided on the top of the guide plate body 15. A rubber plate mounting bolt 17 is threadedly connected to the side surface of the guide plate body 15 near the mounting base 1. After a long period of use, the wear-resistant rubber plate 16 on the top of the guide plate body 15 will experience significant wear. Therefore, by replacing the individual wear-resistant rubber plate 16, the separation efficiency of the entire device will not be affected, thus ensuring the overall separation efficiency and reducing the cost of use.

[0041] Multiple reinforcing crossbars 10 are fixedly installed between the mounting bases 1. Multiple base fixing holes 19 are opened on the surface of the mounting bases 1 and the reinforcing crossbars 10, so as to facilitate the fixed installation of the mounting bases 1.

[0042] The bottom of the protective plate mounting base 6 is threaded with multiple protective plate positioning bolts 20. The protective plate positioning bolts 20 penetrate the protective plate mounting base 6 and are connected to the surface of the inner rotating shaft 5, which can lock and fix the protective plate mounting base 6, increasing the stability during use.

[0043] The implementation principle of this application for a double-layer belt conveyor coal and gangue separation and screening device for mines is as follows: In use, after fixing the device with the mounting base 1, the angle adjustment device 3 adjusts the partition plate mounting slot 11 to a suitable angle. Then, the protective plate mounting base 6 and the protective baffle 7 are flipped upwards, and the protective plate mounting base 6 is fixed with the bottom protective plate positioning bolts 20. During the falling process of coal and gangue, even if splashing occurs, it will be bounced back to the surface of the partition plate body 12 by the blocking effect of the protective baffle 7, thereby minimizing the fall of coal and gangue, improving the overall separation efficiency, and ensuring the cleanliness of the ground. After prolonged use, the wear-resistant rubber plate 16 above the guide plate body 15 will experience significant wear. Replacing the individual wear-resistant rubber plate 16 will not affect the separation efficiency of the entire device, ensuring overall separation efficiency and reducing operating costs.

[0044] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
