[0001] This utility model relates to the field of coal processing technology, specifically to a lifting device for coal processing. Background Technology

[0002] Coal processing (also known as coal preparation or coal washing) refers to the process of purifying, classifying, and upgrading raw coal through physical, chemical, or biological methods to improve coal quality, reduce impurity content, and make it more suitable for different industrial applications.

[0003] In coal processing, the coal needs to be lifted to the feed inlet of the processing equipment before machining. Existing coal lifting devices require two separate actions for lifting and unloading the coal, resulting in discontinuous operation, low efficiency, and a need for improved applicability. Summary of the Invention

[0004] The purpose of this utility model is to provide a lifting device for coal processing, which provides smooth and continuous lifting and unloading of coal, high efficiency, and the ability to unload at different heights, meeting the advantages of different occasions and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for coal processing, comprising a lifting frame and a hopper disposed within the lifting frame. A support base is connected to the bottom of the hopper, and an arc-shaped groove is provided within the support base. A connecting shaft is slidably connected to the arc-shaped groove, and support wheels are rotatably connected to both ends of the connecting shaft. The support wheels are matched with support grooves disposed on the front side of the lifting frame. The lifting frame is connected to a driving mechanism for driving the hopper to rise and fall. The driving mechanism is connected to the connecting shaft. A guiding mechanism for guiding the hopper is connected to the rear side of the lifting frame. The guiding mechanism includes two guide rails, two guide grooves, two rotating wheels, two fixed shafts, and a positioning mechanism. The guide rails are movably connected to the rear side of the lifting frame. The guide grooves are disposed within the guide rails. One end of each fixed shaft is fixedly connected to the hopper, and the other end is rotatably connected to a rotating wheel. The rotating wheel is connected within the guide groove. The positioning mechanism is used for synchronous positioning of the two guide rails.

[0006] Preferably, the drive mechanism includes a motor, two rotating shafts, two drive teeth, two driven teeth, and two chains. The two rotating shafts are distributed vertically, and both ends of the rotating shafts are rotatably connected to the lifting frame. The drive teeth are fixedly connected to the lower rotating shaft, and the driven teeth are fixedly connected to the upper rotating shaft. The drive teeth and driven teeth are connected by chain drive. The motor is connected to the lifting frame, and the power output end of the motor is connected to the lower rotating shaft.

[0007] Preferably, the chain and the connecting shaft are connected by a connecting plate, which includes two clamps and multiple bolts. One clamp is fixedly connected to the chain, and the other clamp is fixedly connected to the connecting shaft. The two clamps are locked together by bolts.

[0011] Preferably, the guide rail has an L-shaped structure.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model, by setting up a drive mechanism and a guide mechanism, uses a motor to drive a chain to move, which can lift and lower the hopper. When the hopper rises to a certain height, the motor continues to drive the chain to move, and the rotating wheel abuts against the top end face of the guide rail. The chain can lift the bottom of the hopper, causing it to rotate around a fixed axis, thereby realizing the unloading action. After unloading is completed, the motor drives the chain to rotate back, and the bottom of the hopper gradually rotates back to its original position. Then, the hopper descends along the height direction of the lifting frame, making it easy to load materials into the hopper. This achieves smooth and continuous lifting and unloading of coal, resulting in high efficiency. The guide rail provides good guidance for the hopper, and the guide rail can be moved and its position changed to achieve unloading at different heights, meeting the needs of different occasions and having strong applicability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4. This utility model provides a lifting device for coal processing, including a lifting frame 1 and a hopper 2 disposed within the lifting frame 1. The bottom of the hopper 2 is connected to a support base 3, and an arc-shaped groove 20 is disposed within the support base 3. A connecting shaft 19 is slidably connected to the arc-shaped groove 20. Support wheels 17 are rotatably connected to both ends of the connecting shaft 19. The support wheels 17 are matched with a support groove 16 disposed on the front side of the lifting frame 1. The connecting shaft 19 provides support for the hopper 2. During the unloading process, the bottom of the hopper 2 rotates around a fixed shaft 22, while the connecting shaft 19 slides within the arc-shaped groove 20 in the direction shown in Figure 2b. The lifting frame 1 is connected to a drive mechanism for lifting the hopper 2. The drive mechanism is connected to the connecting shaft 19. The rear side of the lifting frame 1 is connected to a guide mechanism for guiding the hopper 2. The guide mechanism includes two guide rails 10, two guide grooves 13, two rotating wheels 21, two fixed shafts 22, and a positioning mechanism. The guide rails 10 are movably connected to the rear side of the lifting frame 1. The guide grooves 13 are set in the guide rails 10. One end of the fixed shaft 22 is fixedly connected to the hopper 2, and the other end is rotatably connected to the rotating wheel 21. The rotating wheel 21 is connected in the guide groove 13. The positioning mechanism is used for synchronous positioning of the two guide rails 10.

[0020] The guide rail 10 has an L-shaped structure and includes a vertical rail and an arc-shaped rail. During the upward movement of the hopper 2, the rotating wheel 21 rotates within the vertical rail, and the support wheel 17 rotates within the support groove 16. When the rotating wheel 21 enters the arc-shaped rail, the motor 12 continues to drive the chain 7. The rotating wheel 21 abuts against the top end face of the guide rail 10, which is shown as a in Figure 4. The chain 7 can lift the bottom of the hopper 2, causing it to rotate around the fixed shaft 22, thereby realizing the material unloading action.

[0021] The drive mechanism includes a motor 12, two rotating shafts 5, two drive teeth 4, two driven teeth 6, and two chains 7. The two rotating shafts 5 are arranged vertically, and both ends of the rotating shafts 5 are rotatably connected to the lifting frame 1. The drive teeth 4 are fixedly connected to the lower rotating shaft 5, and the driven teeth 6 are fixedly connected to the upper rotating shaft 5. The drive teeth 4 and driven teeth 6 are connected by the chains 7. The motor 12 is connected to the lifting frame 1, and the power output end of the motor 12 is connected to the lower rotating shaft 5. The motor 12 can drive the lower rotating shaft 5 to rotate, which in turn drives the two drive teeth 4 to rotate. In conjunction with the chains 7, driven teeth 6, and upper rotating shaft 5, the two chains 7 operate synchronously. The chains 7 drive the connecting shaft 19 to move, facilitating the lifting action of the hopper 2.

[0022] Both the driving tooth 4 and the driven tooth 6 are gear structures.

[0023] The chain 7 is connected to the connecting shaft 19 via a connecting plate 18. The connecting plate 18 includes two clamps and multiple bolts. One clamp is fixedly connected to the chain 7, and the other clamp is fixedly connected to the connecting shaft 19. The two clamps are connected by bolts to improve the stability of the connection between the chain 7 and the connecting shaft 19.

[0024] Two vertical slots 15 are provided on the rear side of the lifting frame 1. The guide rail 10 is slidably connected to the vertical slots 15, which guides the guide rail 10 and improves the stability of the movement of the guide rail 10.

[0025] The positioning mechanism includes a U-shaped plate 14, two fixed plates 8, multiple positioning bolts 9, and multiple positioning slots 11. Both ends of the U-shaped plate 14 are fixedly connected to two guide rails 10. The positioning slots 11 are located on the sides of the guide rails 10, and the positioning bolts 9 pass through the fixed plates 8 and connect to the corresponding positioning slots 11. The guide rails 10 can be driven to move along the length of the vertical groove 15, and the U-shaped plate 14 ensures that the movement of the two guide rails 10 remains consistent. The movement of the guide rails 10 changes the position of the arc-shaped track, enabling material pouring at different heights, meeting the needs of various applications and demonstrating strong applicability.

[0026] Once the guide rail 10 is in the appropriate position, the guide rail 10 is locked and fixed using the positioning bolts 9 to improve the stability of the connection between the guide rail 10 and the lifting frame 1.

[0027] The fixing plate 8 is fixed to the lifting frame 1, and the fixing plate 8 is provided with multiple mounting holes. The positioning bolts 9 pass through the corresponding mounting holes and are threadedly connected to the positioning grooves 11.

[0028] Working principle: Hopper 2 is in a lower position, and coal is loaded into it. Motor 12 drives the rotation of the lower rotating shaft 5, which in turn drives the two drive teeth 4 to rotate. This, combined with the driven teeth 6, chain 7, and the upper rotating shaft 5, enables chain 7 to operate. Chain 7 lifts hopper 2, while the relative position between connecting shaft 19 and arc-shaped groove 20 remains unchanged. Rotating wheel 21 rotates in guide groove 13, and support wheel 17 rotates in support groove 16. When rotating wheel 21 enters the arc-shaped track, motor 12 continues to drive chain 7, connecting shaft 19 slides in arc-shaped groove 20, and rotating wheel 21 abuts against the top end face of guide track 10. Chain 7 can lift the bottom of hopper 2, causing it to rotate around fixed shaft 22, thus achieving the unloading action. After unloading is complete, motor 12 drives chain 7 to rotate, rotating wheel 21 enters the vertical track, and connecting shaft 19 returns to its original position within arc groove 20. The hopper 2 then descends to its lowest position, facilitating continued loading. This ensures smooth and continuous coal lifting and unloading with high efficiency. Furthermore, when dealing with processing equipment at different heights, the guide rail 10 can be moved to change its position, thereby enabling unloading at different heights and meeting the needs of various applications, demonstrating strong applicability.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
