Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a labor-saving water pipe truck with planetary gear transmission function. Background Technology

[0002] Hose reels play a vital role in various scenarios. They can neatly manage water through pipelines, allowing workers to easily pull out the required length for their tasks. After completion, the hose automatically rewinds, preventing messy pipe piles on the ground, reducing safety hazards, significantly improving work efficiency, saving factory space, and beautifying the work environment. In auto repair shops, hose reels provide a stable air supply for pneumatic tools, power testing equipment, and provide water hoses for vehicle washing, facilitating efficient maintenance and repair work. During agricultural irrigation, hose reels quickly wind up water hoses, preventing wear and tear caused by haphazard placement. This not only protects the hoses and extends their lifespan but also makes irrigation easier and more efficient. In home gardening, they neatly store water hoses for garden watering and vehicle washing, avoiding tripping hazards caused by hose laying. In short, hose reels optimize pipeline management, bringing convenience, efficiency, and safety, and widely serving many aspects of production and daily life.

[0003] Existing hose reels, especially traditional hose reels, lack effective damping adjustment mechanisms. When pulling the hose, the drum is prone to excessive rotation due to inertia, leading to hose tangling, knotting, or wear, shortening its service life and affecting work efficiency. Manual operation requires overcoming significant resistance, especially when the hose is long or full of water, which is laborious and difficult to control precisely. In addition, most hose reels rely on manual rewinding or a single elastic structure, and uneven rewinding speed can easily cause hose tangling. Furthermore, they lack flexibility when moving and transporting, limiting their use in complex field terrain. These problems make it difficult for existing hose reels to meet the needs of efficient, labor-saving, and convenient operation. Therefore, we propose a labor-saving hose reel with planetary gear transmission function. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A labor-saving water pipe truck with planetary gear transmission function includes,

[0027] Water pipe cart 1 includes a weighing plate 2, four wheels 3 are rotatably connected to the bottom of the weighing plate 2, a water pipe frame 5 is fixedly connected to the top of the weighing plate 2, a water pipe shaft 6 is fixedly connected inside the water pipe frame 5, a drum 7 is rotatably sleeved on the outside of the water pipe shaft 6, and a water pipe 8 is wound around the outside of the drum 7.

[0028] With the above-mentioned structure, the weighing plate 2 can be pushed and the wheel 3 can be rolled at the same time. At this time, the weighing plate 2 can drive the water pipe frame 5 to move, which in turn drives the water pipe 8 to move. More specifically, when it is necessary to pull one end of the water pipe 8 out from the inside of the water pipe frame 5, the water pipe 8 drives the drum 7 to roll outside the water pipe shaft 6.

[0029] Damping mechanism 4 is used to adjust the rotational damping force of the drum 7 outside the water pipe shaft 6. The damping mechanism 4 includes several damping blocks 17 slidably connected inside the damping shell 9. The several damping blocks 17 are arranged in a circle. The top of the damping blocks 17 is rotatably connected to a planetary gear 11. The inner wall of the damping shell 9 is fixedly connected to a gear ring 10. The outside of the water pipe shaft 6 is fixedly sleeved with a sun gear 12. The gear ring 10 meshes with several planetary gears 11, and the sun gear 12 meshes with several planetary gears 11.

[0030] The damping mechanism 4 also includes a second spiral spring 21 disposed inside the damping shell 9. One end of the second spiral spring 21 is fixedly connected to the outside of the water pipe shaft 6, and the other end of the second spiral spring 21 is fixedly connected to the inner wall of the damping shell 9.

[0031] The second spiral spring 21 is configured such that when the water pipe 8 is in use, the drum 7 rotates outside the water pipe shaft 6, and the second spiral spring 21 contracts and stores force. After the water pipe 8 is used, the second spiral spring 21 expands, and one end of the second spiral spring 21 drives the drum 7 to rotate outside the water pipe shaft 6, so that the water pipe 8 is rewound around the outside of the drum 7.

[0032] The water pipe shaft 6 is externally damped and rotatably connected to the damping shaft 13, and the sun gear 12 is fixedly connected to the outside of the damping shaft 13.

[0033] An outer ring 20 is fixedly connected to one side of the inner wall of the damping shell 9. One side of several damping blocks 17 is slidably connected to the inner wall of the outer ring 20. The top of several damping blocks 17 is rotatably connected to a planetary shaft 19. Several planetary gears 11 are fixedly sleeved on the outside of the adjacent planetary shafts 19.

[0034] An inner ring 14 is fixedly connected to one side of the inner wall of the damping shell 9. A clearance groove 16 is provided on one side of the inner ring 14. A first worm spring 15 is provided inside the inner ring 14. One end of the first worm spring 15 extends to the outside of the inner ring 14 through the clearance groove 16. An abutment block 18 is slidably connected to one side of the damping block 17. One end of the abutment block 18 abuts against the outside of the first worm spring 15. One end of the first worm spring 15 is fixedly connected to the outside of the damping shaft 13.

[0035] With the above-mentioned structure, when pulling one end of the water hose 8, the extension length of the water hose 8 due to inertia of the drum 7 can be avoided from exceeding the desired length, which would cause the water hose 8 to become knotted or clogged, reducing its service life. Specifically, when the water hose 8 is extended or retracted, the drum 7 rotates outside the water hose shaft 6. The rotation of the drum 7 drives the damping shell 9 to rotate, which in turn drives the gear ring 10 to rotate. The rotation of the gear ring 10 drives the planetary gear 11 to rotate outside the planetary shaft 19. At the same time, the damping block 17 slides inside the outer ring 20 and drives the sun gear 12 to rotate outside the water hose shaft 6, so that the water hose 8 can be easily wound out from the outside of the drum 7.

[0036] When the water pipe 8 is pulled too fast, the damping shaft 13 rotates with the damping shell 9, and the first spiral spring 15 expands. At this time, the outside of the first spiral spring 15 abuts against one side of several abutting blocks 18, and several damping blocks 17 are damped and engaged with the inner wall of the outer ring 20 through the abutting blocks 18, thereby increasing the damping force of the water pipe 8 and preventing the drum 7 from continuing to rotate due to inertia after the water pipe 8 is pulled quickly and stopped, which would cause the water pipe 8 to pile up, reduce the life of the water pipe 8 and hinder the normal operation of the water pipe 8.

[0037] Working principle: When the water pipe cart 1 needs to be used, the weighing plate 2 is pushed. As the weighing plate 2 moves, the wheels 3 roll. At this time, the weighing plate 2 can drive the water pipe frame 5 to move, which in turn drives the water pipe 8 to move. The water pipe cart 1 can be moved to the required position. When it is necessary to pull one end of the water pipe 8 out from the inside of the water pipe frame 5, the water pipe 8 drives the drum 7 to roll outside the water pipe shaft 6.

[0038] When the water hose 8 is extended or retracted, the drum 7 rotates outside the water hose shaft 6. The rotation of the drum 7 drives the damping shell 9 to rotate, the rotation of the damping shell 9 drives the gear ring 10 to rotate, and the rotation of the gear ring 10 drives the planetary gear 11 to rotate outside the planetary shaft 19. At the same time, the damping block 17 slides inside the outer ring 20 and drives the sun gear 12 to rotate outside the water hose shaft 6, so that the water hose 8 can be easily rolled out from the outside of the drum 7.

[0039] When the water pipe 8 is pulled too fast, the damping shaft 13 rotates with the damping shell 9, and the first volute spring 15 expands. At this time, the outside of the first volute spring 15 abuts against one side of several abutting blocks 18, and several damping blocks 17 are damped and engaged with the inner wall of the outer ring 20 through the abutting blocks 18, thereby increasing the damping force of the water pipe 8 and preventing the drum 7 from continuing to rotate due to inertia after the water pipe 8 is pulled quickly and stopped, which would cause the water pipe 8 to pile up, reduce the life of the water pipe 8 and hinder the normal operation of the water pipe 8.

[0040] When the water hose 8 is used, the drum 7 rotates outside the water hose shaft 6. At the same time, the second spiral spring 21 contracts and stores force. After the water hose 8 is used, the second spiral spring 21 expands. One end of the second spiral spring 21 drives the drum 7 to rotate outside the water hose shaft 6, so that the water hose 8 is rewound around the outside of the drum 7.
