Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation equipment technology, specifically to a reel structure for an anti-detachment sprinkler irrigation machine. Background Technology

[0002] In agricultural sprinkler irrigation operations, the coiled structure of the sprinkler machine is used for extending and retracting the water delivery hose. Its stability and anti-detachment performance directly affect irrigation efficiency and the service life of the water delivery hose. Existing sprinkler machine coiled structures generally suffer from the following problems:

[0003] During the winding process, the lack of an effective radial limiting structure on the circumference of the water reel causes the water pipe to easily shift and stack radially along the reel, leading to pipe detachment and tangled winding. The water pipe relies heavily on a fixed guide structure during unwinding and rewinding, making it impossible to adjust the guide position according to changes in the thickness of the water pipe winding on the reel. This results in continuous changes in the unwinding and rewinding angle, easily causing the water pipe to jam, wrinkle, or even wear. Furthermore, some reels have fixed-size axial limiting structures at both ends, which cannot accommodate water pipes of different diameters, resulting in poor versatility. Frequent replacement of limiting components is required to meet the needs of different water pipe specifications, increasing equipment maintenance costs and downtime. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the water pipe of the existing sprinkler irrigation machine coil structure is prone to falling off, uneven winding, damage to the water pipe due to rigid limiting, and cumbersome operation. It achieves radial anti-detachment of the water pipe, axial limiting protection, and adaptive neat winding, thereby improving the stability, versatility and ease of operation of the coil structure and reducing water pipe wear.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A sprinkler reel structure for preventing detachment includes a frame, on which an anti-detachment reel is rotatably mounted. The anti-detachment reel includes a reel body and circular baffles at both ends. The circumferential surface of the anti-detachment reel is provided with several annular limiting protrusions, which are distributed parallel to each other along the axial direction of the reel. Adjacent limiting protrusions form limiting grooves that are adapted to the outer diameter of the water supply pipe.

[0007] The frame is equipped with an adaptive guide assembly located on one side of the anti-detachment reel, which guides the water supply pipe into the limiting groove along the axis of the anti-detachment reel. Both ends of the anti-detachment reel are fixed with elastic axial limiting assemblies to limit the axial displacement of the water supply pipe.

[0008] As an improvement, the limiting protrusion is integrally formed on the circumferential surface of the reel body, the diameter of the baffle is larger than the outer diameter of the reel body, and the elastic axial limiting component is fixed to the inner sidewall of the baffle.

[0009] As an improvement, the adaptive guide assembly includes a slider, a guide wheel, and a counterweight. The top of the frame is provided with a slide rail extending along the axial direction of the anti-detachment reel. The slider slides in cooperation with the slide rail. The guide wheel is rotatably mounted on the side of the slider facing the anti-detachment reel, and its groove is adapted to the outer wall of the water pipe. The counterweight is connected to the side of the slider away from the anti-detachment reel through a connector. By gravity pulling the slider, the guide wheel is always in contact with the outer tube of the reel.

[0010] As an improvement, the guide wheels are distributed on one side of the water pipe, with a rounded transition at the edge of the wheel groove. The connecting part is a flexible pull rope, one end of which is fixed to the top of the slider and the other end is connected to the counterweight. The length of the pull rope is adapted to the sliding stroke of the slider.

[0011] As an improvement, the elastic axial limiting component includes an elastic buffer layer and an adjusting baffle. The elastic buffer layer is fixed to the inner wall of the anti-detachment reel baffle, and its surface is in elastic contact with the end face of the water supply pipe. The adjusting baffle is an arc-shaped plate, which is connected to the edge of the baffle by bolts. The extension length of the adjusting baffle along the radial direction of the reel is adjustable, and its inner side is in contact with the outer wall of the water supply pipe.

[0012] As an improvement, the adjustable baffles are spaced apart along the circumference of the baffle, with a pre-reserved expansion gap between adjacent baffles, and an arc-shaped contact surface adapted to the water pipe is provided on the inner side of the baffle.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. This utility model forms a limiting groove that matches the outer diameter of the water pipe by using the limiting protrusion on the circumferential surface of the anti-detachment reel. Combined with the blocking effect of the baffle, it achieves radial stability limiting of the water pipe, completely solving the problem of water pipe displacement and detachment caused by the lack of radial limiting in traditional reels, and ensuring the neatness of the water pipe winding.

[0015] 2. This utility model achieves adaptive adjustment of the guide position according to the winding thickness of the water pipe through an adaptive guide component. The counterweight block pulls the slider along the slide rail through a flexible pull rope, so that the guide wheel always fits the outer tube of the anti-detachment reel. Compared with the traditional fixed guide structure, it avoids abnormal winding and unwinding angles and tube jamming caused by changes in the winding thickness of the water pipe, thus improving the winding and unwinding efficiency of the water pipe.

[0016] 3. The elastic axial limiting component of this utility model can achieve adjustable extension length through the bolt connection of the adjusting baffle. With the elastic contact of the elastic buffer layer, it can not only adapt to water pipes of different diameters, but also buffer the axial impact force when the water pipe is extended and retracted. Compared with the traditional fixed size limiting structure, it can meet the usage needs of various specifications of water pipes without frequent replacement of parts, thus reducing equipment maintenance costs.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4As shown, an anti-detachment sprinkler reel structure includes a frame 1, which is a metal frame structure used to provide overall support. An anti-detachment reel 2 is rotatably mounted between two upright plates on both sides of the frame 1 via bearings. The reel body 21 is a hollow cylindrical structure, with circular baffles 22 at both ends fixed to the reel body 21 by welding. The diameter of the baffles 22 is larger than the outer diameter of the reel body 21. A limiting ridge 4 is an annular protrusion integrally formed along the circumference of the reel body 21. The spacing between adjacent ridges is adapted to the outer diameter of the water pipe to be used, forming a limiting groove. An adaptive guide assembly 3 is located on one side of the anti-detachment reel 2. The top slide rail 11 is a metal strip track, which is fixed by bolts. The slider 31 is a metal block, and its bottom is slidably engaged with the slide rail 11. The guide wheel 32 is rotatably mounted on the side wall of the slider 31 through a rotating shaft. The wheel groove arc is adapted to the outer wall of the water pipe. The connector 34 is a nylon flexible pull rope, one end of which is fixed to the top hook of the slider 31, and the other end is connected to the counterweight 33 (metal block structure). The elastic buffer layer 51 of the elastic axial limiting component 5 is made of rubber and is fixed to the inner side wall of the baffle 22 by adhesive. The adjusting baffle 52 is a metal arc plate, which is connected to the reserved hole on the edge of the baffle 22 by bolts 53.

[0026] See appendix Figure 2 Appendix Figure 3 and attached Figure 5 As shown, the guide wheel 32 has its groove edge polished to form a rounded transition. The length of the pull rope of the connector 34 is set according to the length of the slide rail 11 to ensure that the pull rope is not slack or overly tight when the slider 31 slides to both ends of the slide rail 11. The adjusting baffle 52 is evenly distributed along the circumference of the baffle 22, and a telescopic gap is reserved between adjacent baffles. The arc of the inner side of the adjusting baffle 52 is adapted to the outer wall of the water pipe. The elastic buffer layer ensures that there is sufficient buffering when it makes elastic contact with the end face of the water pipe.

[0027] In the specific implementation of this utility model: during the component installation preparation stage, check the connection and status of each component: confirm that the frame 1 is structurally stable, the anti-detachment reel 2 rotates smoothly on the frame 1 without jamming, the limiting protrusion 4 is not deformed or detached, the slider 31 of the adaptive guide component 3 slides flexibly along the slide rail 11, the guide wheel 32 rotates freely, and the elastic buffer layer 51 of the elastic axial limiting component 5 is undamaged and the bolts 53 are not loose; according to the diameter of the water pipe to be used, adjust the adjusting baffle 52 of the elastic axial limiting component 5: loosen the bolts 53, along the baffle 2 2. Adjust the radially moving stop 52 so that the arc-shaped contact surface on the inner side of the adjusting stop 52 fits against the outer wall of the water pipe. Then tighten the bolt 53 to fix the position of the stop. If the diameter of the water pipe is different, repeat the above steps to adjust the extension length of the stop. Fix one end of the water pipe to the reel body 21 of the anti-detachment reel 2, complete the initial winding along the limiting groove, and lead out the other end, pass through the guide wheel 32 groove of the adaptive guide component 3, adjust the initial position of the counterweight 33 so that the guide wheel 32 fits tightly against the outer wall of the water pipe to ensure that there is no deviation when the water pipe is wound up and down.

[0028] During the operation of the sprinkler irrigation machine: The drive unit of the sprinkler irrigation machine is started, and the anti-detachment reel 2 rotates at a constant speed around its own axis to achieve the winding or unwinding of the water pipe. When winding the water pipe, as the thickness of the water pipe winding on the reel gradually increases, the outer layer of the water pipe pushes the guide wheel 32, causing the slider 31 to slide along the slide rail 11 away from the center of the reel. The counterweight 33 maintains tension on the slider 31 through the flexible rope, ensuring that the guide wheel 32 remains in contact with the outer wall of the water pipe and preventing the water pipe from detaching from the limiting groove. When unwinding the water pipe, the thickness of the water pipe winding on the reel gradually decreases, and the gravity of the counterweight 33 pulls the slider 31 along the slide rail 11 towards the center of the reel. As the guide wheel 32 slides in the direction of the slider, it remains in contact with the outer tube, maintaining a stable release angle for the water pipe. Simultaneously, the elastic buffer layer 51 of the elastic axial limiting component 5 elastically contacts the end face of the water pipe, buffering the axial impact force during retraction and extension. The adjusting baffle 52 prevents the water pipe from axially shifting, completely preventing it from detaching from both ends of the reel. The arc transition structure of the guide wheel 32's groove prevents the water pipe from being scratched during retraction and extension, ensuring the integrity of the pipe. During operation, if a different diameter water pipe needs to be replaced, simply loosen the bolt 53 and adjust the extension length of the adjusting baffle 52; no other parts need to be disassembled or replaced, effectively shortening equipment adjustment time.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
