An automatic water pipe retractor

Abstract

This utility model discloses an automatic water pipe coiler, including a bracket and a coiling disc. The coiling disc is rotatably mounted on the bracket, and side supports are provided on both sides of the bracket. The side supports are connected to a pipe outlet guide plate, and a drive roller is provided on the pipe outlet guide plate. A motor is provided on the side supports, and the motor drives the drive roller. A large gear ring is provided on the side of the coiling disc, and the motor also drives the large gear ring. The coiling and uncoiling modes can be quickly switched through an adjustable gear mechanism. Users can select to mesh with different auxiliary gears by pushing and pulling the adjustable gear, thereby driving the coiling disc to coil or the drive roller to actively uncoil the pipe. The integrated design significantly improves the convenience of operation and work efficiency. Using a drive roller to uncoil the pipe is more reasonable than the reverse rotation of the coiling disc.

Description

Technical Field

[0001] This utility model belongs to the field of garden equipment technology, specifically relating to an automatic water pipe retractor. Background Technology

[0002] Traditional pipe winding and unwinding methods rely heavily on manual operation, which is inefficient and labor-intensive, especially in long-distance, large-diameter applications. To improve operational efficiency, various pipe winding and unwinding devices have emerged on the market, such as manual crank-type pipe winders or motor-driven pipe reeling equipment. However, existing equipment generally suffers from problems such as limited functionality or inconvenient operation: some devices can only perform one function, either winding or unwinding, and cannot be flexibly switched within the same system; others, while powered, lack effective pipe guiding and protection mechanisms, easily causing pipe twisting, wear, or even jamming. Utility Model Content

[0003] The purpose of this invention is to provide an automatic water pipe retractor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic water pipe coiler, comprising a bracket and a winding disc, the winding disc being rotatably mounted on the bracket, side supports being provided on both sides of the bracket, the side supports being connected to a pipe outlet guide plate, a drive roller being provided on the pipe outlet guide plate, a motor being provided on the side supports, the motor driving and connecting to the drive roller, a large gear ring being provided on the side of the winding disc, the motor also driving and connecting to the large gear ring.

[0005] Preferably, two sets of drive rollers are provided, each set of drive rollers is provided with a shaft, the shaft is connected to a shaft transmission box, the shaft transmission box is also provided with a shaft transmission box input gear, a motor transmission box is also provided on one side of the side support, the two ends of the motor transmission box are respectively provided with a motor transmission box input gear and a motor transmission box output gear, the motor transmission box output gear meshes with the shaft transmission box input gear, a rotating rod is also provided on the side support, the rotating rod is provided with two auxiliary gears, the two auxiliary gears mesh with the motor transmission box input gear and the large gear ring respectively, the motor drive is connected to an adjustable gear, and the adjustable gear is connected to the auxiliary gears.

[0006] Preferably, side guard rollers are also provided on both sides of the drive roller.

[0007] Preferably, the outlet guide plate has an opening in the middle, and the drive roller is disposed in the opening.

[0008] Preferably, each set of drive rollers has two rollers, and the two sets of drive rollers rotate in opposite directions.

[0009] The technical effects and advantages of this utility model are as follows: 1. The adjustable gear mechanism enables quick switching between the tube winding and unwinding modes; users can select to mesh with different auxiliary gears simply by pushing and pulling the adjustable gear, thereby driving the tube winding disc to wind up or driving the roller to actively unwind the tube. The integrated design significantly improves the ease of operation and work efficiency. Using a drive roller for pipe feeding is more reasonable than using a pipe-winding disc to feed pipes in the opposite direction. The existing method of feeding pipes by rotating the pipe-winding disc in the opposite direction will cause all the water pipes on the pipe-winding disc to loosen, resulting in pipe feeding failure. The device employs a combined gear transmission system consisting of a motor drive box and a shaft drive box, along with a meshing structure between a large gear ring and a secondary gear, achieving efficient power transmission and direction conversion. The overall layout is reasonable, reducing redundant components, and the device has a compact structure, making it easy to install and move. The complete adoption of electric motor drive to replace manual operation significantly reduces labor intensity and time costs, making it particularly suitable for large-scale, frequent water pipe opening and closing applications, such as agricultural irrigation systems and garden irrigation.

[0012] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0013] This utility model provides, for example Figure 1-2 An automatic water pipe retractor is shown, comprising a bracket 1 and a pipe winding disc 2. The pipe winding disc 2 is rotatably mounted on the bracket 1. Side supports 3 are provided on both sides of the bracket 1. The side supports 3 are connected to the pipe outlet guide plate 4.
