Description

Technical Field

[0001] This utility model relates to the field of reel technology, specifically to an automatic reel for garden irrigation sprinklers. Background Technology

[0002] Garden irrigation is a technical measure to replenish the soil moisture required for the growth of garden plants, thereby improving their growing conditions. Various methods, both manual and mechanical, are used to replenish the soil moisture in garden green spaces to meet the water needs of plants. A search revealed a Chinese patent with authorization announcement number CN212127110U, which discloses a rapid-release reel, relating to the field of underground tunnel cleaning technology. The rapid-release reel includes a component to be installed, a support, and a reel assembly. The component to be installed is mounted on the outer periphery of a wall or external pipe. The support is rotatably mounted on the component around a first rotation center axis. The reel assembly includes a water pipe, a coil, and a reel for winding the coil. The water pipe is fixedly connected to the support, and its extension direction is perpendicular to the first rotation center axis. The reel is rotatably fitted onto the outer periphery of the water pipe. The water pipe has an inlet connected to an external water supply device and an outlet connected to the coil. The coil is made of a non-metallic material. With this setup, when cleaning the tunnel, the parts to be installed are fixed to the wall or pipe, and the coil is pulled directly to the cleaning position. The water inlet of the water pipe is connected to the water supply equipment, which saves manpower and time, is highly efficient, and the pipe is not easily bent, ensuring the smooth progress of the cleaning process.

[0003] Currently, when existing sprinklers are used for garden irrigation, they are usually connected to water pipes, and large-area garden irrigation is achieved by dragging the water pipes. However, such a structure is inconvenient to use, and the water pipes dragging on the ground may damage the vegetation. Utility Model Content

[0004] To address the problem of inconvenient storage and use of existing sprinkler head connection water pipes, this utility model provides an automatic retractable reel for garden irrigation sprinklers.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An automatic reel for garden irrigation nozzles includes a housing, an internally connected winding wheel with a hollow interior, a flexible hose wound around its outer wall, a perforation on one side of the housing's outer wall, one end of the hose passing through the perforation and connected to a nozzle, an interface on one side of the winding wheel communicating with one end of the hose, a rotary joint on the bottom surface of the winding wheel, a drive assembly on the top surface of the housing, and a motor mounted on the top surface of the drive assembly.

[0007] Furthermore, the drive assembly includes a chassis, with a first gear and a second gear rotatably connected to the two sides inside the chassis, the first gear and the second gear meshing with each other, and the diameter of the first gear being larger than the diameter of the second gear.

[0008] The beneficial effects of adopting the above-mentioned further solution are that the chassis provides protection and support for the first gear and the second gear, and the two gears mesh with each other to form a speed reduction transmission structure. The diameter of the first gear is larger than that of the second gear, which can reduce the rotation speed of the winding wheel, avoid the hose from being pulled and broken due to excessively fast winding and unwinding, and at the same time improve the torque output to ensure that the winding wheel can still rotate smoothly when the hose is under load.

[0009] Furthermore, the output end of the motor extends into the interior of the chassis and is connected to one end of the second gear for transmission.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the motor output directly drives the second gear to rotate, and drives the first gear through gear meshing, so as to efficiently transmit the motor power to the winding wheel. The motor drive mode realizes the automatic control of hose reeling and unwinding. The speed can be adjusted by the circuit to adapt to the hose release length requirements in different irrigation scenarios.

[0011] Furthermore, the bottom end of the first gear is connected to a connector, and the top surface of the winding wheel is fitted with a mating sleeve that engages with the connector.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the mating joint at the bottom of the first gear engages with the mating sleeve on the top surface of the winding wheel, ensuring that the power of the drive component is stably transmitted to the winding wheel, avoiding slippage or misalignment during transmission, and ensuring the accuracy of hose winding and unwinding.

[0013] Furthermore, the bottom surface of the outer shell is provided with a pre-embedded column, the pre-embedded column includes an outer cylinder, the bottom surface of the outer shell is welded with the outer cylinder, and an inner tube is installed inside the outer cylinder, the bottom end of the inner tube is connected to the bottom end of the rotary joint.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the pre-embedded column enhances the overall stability of the equipment through the outer cylinder and the base plate, preventing the reel from tipping over when the hose is being wound up or down. The inner pipe connects to the rotary joint and the external water source, realizing the water circuit connection between the fixed pipe and the rotating winding wheel, avoiding the water source pipe from getting tangled as the winding wheel rotates, and ensuring a continuous and smooth water supply.

[0015] Furthermore, an external interface that matches the bottom end of the inner tube is provided on one side of the outer wall of the outer cylinder.

[0016] The advantage of adopting the above-mentioned further solution is that the external interface matches the bottom end of the inner pipe, which facilitates quick connection to the external water supply pipeline.

[0017] Furthermore, a base plate is installed at the bottom end of the outer cylinder.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the base plate increases the contact area between the embedded column and the ground, thereby improving the equipment's resistance to tipping.

[0019] Furthermore, a handle is installed on the outer wall of the nozzle.

[0020] The advantage of adopting the above-mentioned further solution is that the handle provides the operator with a gripping point, making it easy to manually adjust the irrigation angle and position of the sprinkler head, adapting to the precise irrigation needs of irregular areas in the garden.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This automatic reel for garden irrigation sprinklers utilizes a winding wheel, hose, sprinkler head, rotary joint, drive assembly, and motor to facilitate the easy deployment and retraction of the hose carrying the sprinkler head. The outer casing provides installation space for the winding wheel, whose hollow structure, combined with the interface and rotary joint, ensures a continuous connection between the hose and water source, guaranteeing a stable water flow to the sprinkler head during irrigation. The drive assembly, powered by the motor, rotates the winding wheel, automatically deploying and retracting the hose. A pipe hole provides a passage for the hose to pass through, preventing friction damage between the hose and the outer casing during deployment and retraction. This eliminates the need for manual dragging, making it more convenient to use and reducing damage to vegetation caused by the hose. Attached Figure Description

[0031] 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.

[0032] As an embodiment of this utility model, the drive assembly 2 further includes a housing 201.

The first gear 202 and the second gear 203 mesh with each other, and the diameter of the first gear 202 is larger than the diameter of the second gear 203. The housing 201 provides protection and support for the first gear 202 and the second gear 203. The two gears mesh with each other to form a speed reduction transmission structure. The diameter of the first gear 202 is larger than that of the second gear 203, which can reduce the rotation speed of the winding wheel 5, avoid the hose 10 from being pulled and broken due to excessively fast winding and unwinding, and at the same time increase the torque output to ensure that the winding wheel can still rotate smoothly when the hose is under load.

[0033] As an embodiment of this utility model, the output end of the motor 3 extends into the interior of the housing 201 and is connected to one end of the second gear 203 for transmission. The output end of the motor 3 directly drives the second gear 203 to rotate, and drives the first gear 202 through gear meshing, so as to efficiently transmit the motor power to the winding wheel 5. The motor drive mode realizes the automatic control of the hose 10 winding and unwinding. The speed can be adjusted by the circuit to adapt to the hose release length requirements under different irrigation scenarios.

[0034] As an embodiment of this utility model, the bottom end of the first gear 202 is connected to a connector 204, and the top surface of the winding wheel 5 is equipped with a mating sleeve 7 that engages with the connector 204. The connector 204 at the bottom end of the first gear 202 engages with the mating sleeve 7 on the top surface of the winding wheel 5 to ensure that the power of the drive assembly 2 is stably transmitted to the winding wheel, avoid slippage or misalignment during transmission, and ensure the retraction and extension accuracy of the hose 10.

[0035] As one embodiment of this utility model, the bottom surface of the outer shell 1 is further provided with a pre-embedded column 4, which includes an outer cylinder 401. The outer cylinder 401 is welded to the bottom surface of the outer shell 1, and an inner tube 403 is installed inside the outer cylinder 401. The bottom end of the inner tube 403 is connected to the bottom end of the rotary joint 8. The pre-embedded column 4 enhances the overall stability of the equipment through the outer cylinder 401 and the base plate 402, preventing the reel from tipping over when the hose is being wound up or down. The inner tube 403 connects the rotary joint 8 to an external water source, realizing the water path connection between the fixed pipe and the rotating winding wheel, avoiding the water source pipe from getting tangled as the winding wheel rotates, and ensuring a continuous and smooth water supply.

[0036] As an embodiment of this utility model, the outer wall of the outer cylinder 401 is further provided with an outer interface 404 that matches the bottom end of the inner tube 403. The outer interface 404 matches the bottom end of the inner tube 403, which facilitates quick connection to the external water supply pipeline.

[0037] As an embodiment of this utility model, a bottom plate 402 is further installed at the bottom end of the outer cylinder 401. The bottom plate 402 increases the contact area between the embedded column 4 and the ground, thereby improving the equipment's anti-tipping ability.

[0038] As an embodiment of this utility model, a handle 12 is further installed on the outer wall of the nozzle 11.

[0039] Specifically, the working principle of this automatic retractable garden irrigation nozzle is as follows: During use, the pre-embedded post 4 on the bottom surface of the outer casing 1 is securely installed on the ground via the outer cylinder 401 and base plate 402. The inner pipe 403 connects to an external water source via the outer interface 404, and then connects to the hollow structure of the winding wheel 5 via the rotary joint 8. Water flows through the interface 6 into the hose 10 and is delivered to the nozzle 11. When the hose 10 needs to be retracted, the motor 3 drives the second gear 203 inside the housing 201 to rotate, meshing with the first gear 202 to form a reduction transmission. The connector 204 at the bottom of the first gear engages with the mating sleeve 7 on the top surface of the winding wheel, driving the winding wheel 5 to rotate, thus automatically retracting the hose through the pipe hole 9. The gear transmission of the drive assembly 2 reduces the rotational speed and increases the torque, ensuring smooth hose retraction and retraction. The handle 12 of the nozzle 11 facilitates manual adjustment of the irrigation angle. The entire system, through the synergy of mechanical transmission and water circuit design, achieves automation and convenience in garden irrigation.
