DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] A discharging device for wharf loading and unloading, including a bottom plate 1, two support frames 2 are fixedly connected to the top of the bottom plate 1, a moving plate 3 is arranged outside the two support frames 2, two fixing plates 4 are fixedly connected to the top of the two moving plates 3, two connecting seats are fixedly connected to the top of the fixing plate 4, a discharging plate 5 is rotatably connected between the two connecting seats, and further includes:

[0027] A lifting assembly, which is located at the top of the two support frames 2 and is connected to the fixing plate 4 for adjusting the height of the fixing plate 4;

[0028] A tilting assembly, which is located on the outer surface of the fixing plate 4 and is connected to the discharging plate 5 for driving the discharging plate 5 to tilt. Through the connecting rod 16, the discharging plate 5 tilts around its connection point with the fixing plate 4 to realize the discharging work.

[0029] Furthermore, the lifting assembly includes a handle 7, a bidirectional threaded rod 8, connecting rods 12 and connecting rings 13. Two connecting rods 12 are rotatably connected to the top of each support frame 2. The tops of the four connecting rods 12 are rotatably connected to the bottom of the fixing plate 4. The four connecting rods 12 are in a rhombus shape and are rotatably connected to each other. Two connecting rings 13 are fixedly connected inside each of the four connecting rods 12. The four connecting rings 13 on the same side are internally threadedly sleeved with the bidirectional threaded rod 8. The ends of the two bidirectional threaded rods 8 are fixedly connected with handles 7. The staff rotates the handle 7 to drive the bidirectional threaded rod 8 to rotate. Since the thread directions of the bidirectional threaded rod 8 are opposite and it is threadedly sleeved with the four connecting rings 13 at the same time, when the bidirectional threaded rod 8 rotates, the four connecting rings 13 will approach or move away from each other. The movement of the connecting rings 13 will drive the connecting rods 12 to rotate. Since the connecting rods 12 are rotatably connected to each other and to the fixing plate 4 and the support frames 2, and the overall structure is in a rhombus shape, when the connecting rods 12 rotate, it will drive the fixing plate 4 to rise or fall along the guide of the support frames 2.

[0030] Furthermore, two guide rails 17 are fixedly connected to the outer surfaces of the two support frames 2. The two guide rails 17 are internally slidably connected to the moving plate 3. A connecting plate is fixedly connected to the top of the two support frames 2. The connecting plate is located below the fixing plate 4. The guide rails 17 on the outer surfaces of the support frames 2 provide a sliding path for the moving plate 3 to ensure its stability and directionality during the lifting process.

[0031] Further, the dumping assembly includes a driving motor 9, a threaded rod 10, a moving block 11, a fixed block 14, a connecting rod 16, and a bearing seat 18. Two bearing seats 18 are fixedly connected to the top of the fixed plate 4. A threaded rod 10 is rotatably connected between the two bearing seats 18. A moving block 11 is threadedly sleeved on the outer surface of the threaded rod 10. Connecting rods 16 are rotatably connected to the outer surfaces on both sides of the moving block 11. A fixed block 14 is fixedly connected to the bottom of the discharge plate 5. The outer surfaces on both sides of the fixed block 14 are rotatably connected to the other ends of the corresponding connecting rods 16. A driving motor 9 is fixedly installed on the outer surface of one of the bearing seats 18. The output end of the driving motor 9 is fixedly connected to the end of the threaded rod 10. The output end of the driving motor 9 drives the threaded rod 10 to rotate. Since the moving block 11 is threadedly sleeved on the threaded rod 10, when the threaded rod 10 rotates, the moving block 11 will move along the axial direction of the threaded rod 10. The movement of the moving block 11 drives the fixed block 14 to move through the connecting rod 16. Since the fixed block 14 is fixedly connected to the bottom of the discharge plate 5, and the two ends of the connecting rod 16 are respectively rotatably connected to the moving block 11 and the fixed block 14, when the moving block 11 moves, the discharge plate 5 will be tilted around its connection point with the fixed plate 4 through the connecting rod 16. The notch 15 on the outer surface of the fixed block 14 is designed to accommodate the end of the connecting rod 16 and maintain stable connection during the tilting process of the discharge plate 5.

[0032] Further, a notch 15 is formed on the outer surface of the fixed block 14. The notch 15 is arranged in an arc structure, and the threaded rod 10 is located within the notch 15.

[0033] Further, two limit blocks 19 are fixedly connected to the top of the discharge plate 5. Rubber pads 20 are fixedly connected to the tops of the two limit blocks 19. The limit blocks 19 on the top of the discharge plate 5 and the rubber pads 20 thereon play a buffering role.

[0034] Further, universal wheels 6 are fixedly installed at the four corners of the bottom of the bottom plate 1. The universal wheels 6 at the bottom of the bottom plate 1 facilitate the flexible movement of the entire device on the dock and meet the requirements of different loading and unloading positions.

[0035] Working principle: When the staff needs to use the unloading device for dock loading and unloading, the staff rotates the handle 7 to drive the rotation of the bidirectional threaded rod 8. Since the thread directions of the bidirectional threaded rod 8 are opposite and it is threadedly sleeved with four connecting rings 13 at the same time, when the bidirectional threaded rod 8 rotates, the four connecting rings 13 will approach or move away from each other. The movement of the connecting ring 13 will drive the connecting rod 12 to rotate. Since the connecting rods 12 are rotationally connected to each other and to the fixed plate 4 and the support frame 2, and the overall structure is a rhombus, when the connecting rod 12 rotates, it will drive the fixed plate 4 to rise or fall along the guide of the support frame 2, thereby adjusting the height of the fixed plate 4 and the unloading plate 5 thereon. After adjusting to the appropriate height, the driving motor 9 is started. The output end of the driving motor 9 drives the rotation of the threaded rod 10. Since the moving block 11 is threadedly sleeved with the threaded rod 10, when the threaded rod 10 rotates, the moving block 11 will move along the axial direction of the threaded rod 10. The movement of the moving block 11 drives the fixed block 14 to move through the connecting rod 16. Since the fixed block 14 is fixedly connected to the bottom of the unloading plate 5 and the two ends of the connecting rod 16 are rotationally connected to the moving block 11 and the fixed block 14 respectively, when the moving block 11 moves, it will cause the unloading plate 5 to tilt around its connection point with the fixed plate 4 through the connecting rod 16, thereby realizing the unloading work. The notch 15 on the outer surface of the fixed block 14 is designed to accommodate the end of the connecting rod 16 to maintain a stable connection during the tilting process of the unloading plate 5. When the unloading plate 5 is in a horizontal state, the limit block 19 on the top of the unloading plate 5 and the rubber pad 20 thereon play a buffering role, and the threaded rod 10 is located in the notch 15. The guide rail 17 on the outer surface of the support frame 2 provides a sliding path for the moving plate 3 to ensure its stability and directionality during the lifting and lowering process. The universal wheels 6 at the bottom of the bottom plate 1 facilitate the flexible movement of the entire device on the dock to meet the requirements of different loading and unloading positions.
