Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, and specifically discloses a spray watering device for garden plants. Background Technology

[0002] In the maintenance of garden plants, sprinkler irrigation devices are key equipment for achieving efficient and uniform irrigation. There are already a variety of adjustable sprinkler devices in the existing technology. For example, Chinese utility model patent with announcement number CN213486202U discloses a sprinkler irrigation device for garden plants. This device achieves the height adjustment of the nozzle through the cooperation of the cross-shaped locking block and the cross-shaped groove of the column, and achieves the angle adjustment of the nozzle through the spherical hinge structure, which improves the flexibility of use to a certain extent. However, through in-depth analysis and practice, the applicant has discovered that existing devices of this type still have significant technical defects, which limit their practical application effectiveness and reliability: 1. This patent achieves height adjustment through "cross-shaped locking blocks and cross-shaped grooves," but it can only move in one direction along the column axis and cannot achieve overall horizontal rotation of the device. This results in the nozzles only being able to cover plants in a fixed direction, requiring frequent movement of the device to complete multi-directional spraying. At the same time, its height fixation relies on a single-point contact fixation of "clamping nuts pressing against the outer wall of the column." After long-term water flow impact or external force collision, the clamping nuts are prone to loosening, causing the nozzle height to deviate, requiring repeated calibration. 2. This patent uses an angle adjustment structure of "spherical seat, rotating ball, and clamping bolt". The clamping bolt directly presses against the rotating ball to achieve locking, which is a point contact fixation. Long-term use can easily cause wear on the outer wall of the rotating ball, resulting in the angle shifting on its own. In addition, there is no angle positioning scale or limit structure. Each adjustment requires repeated test spraying to confirm the angle, which cannot achieve precise positioning and reduces spraying efficiency. In summary, existing sprinkler irrigation devices have inherent shortcomings in terms of the stability and precision of their adjustment functions. Therefore, there is an urgent need for a new type of sprinkler irrigation device that can achieve precise adjustment with multiple degrees of freedom and maintain a stable and reliable working state for a long time after adjustment.

[0021] In this embodiment: When the sprinkler irrigation device is working, it is first securely installed in the designated position through the through hole 24 and ground anchor 25 on the base 1; after the water source is connected, the water flows through the delivery hose 5 to the nozzle 4; when it is necessary to adjust the spray coverage area, the user can pull out the pin 9 to drive the entire angle adjustment mechanism 3 to rotate horizontally around the rotating support platform 2 to the desired position, and then insert the pin 9 into the corresponding set of holes 8 to achieve reliable horizontal positioning; the operation handwheel 2 of the worm gear assembly 13 is rotated. 1. Drive the worm gear 20 to rotate the worm wheel 19 and the horizontal rotating shaft 11 coaxial with it, thereby precisely adjusting the pitch angle of the articulated arm 12, and reliably locking the angle by utilizing the self-locking characteristics of the worm wheel 19 and worm gear 20; finally, loosen the wing nut, rotate the nozzle 4 until a certain limiting hole 16 on its adjusting shaft 15 is aligned with the locking pin 17, and then tighten the wing nut so that the locking pin 17 is inserted into the limiting hole 16, thereby quickly and accurately fixing the final spray direction of the nozzle 4, achieving stable and efficient fixed-point spraying.

[0022] As a technical optimization of this utility model, a lifting ring 18 is provided at the top of the pin 9.

[0023] In this embodiment: the lifting ring 18 facilitates the user to quickly insert and remove the pin 9, improves the operational efficiency of horizontal rotation positioning, and avoids operational inconvenience caused by the lack of leverage points for the pin 9.

[0024] As a technical optimization of this utility model, the worm gear assembly 13 includes a worm gear 19 coaxially fixed with the horizontal rotating shaft 11, a worm 20 meshing with the worm gear 19, and an operating handwheel 21 for driving the worm 20 to rotate. The worm gear 19 and the worm 20 are housed in a gearbox 22 fixed on the support arm 10.

[0025] In this embodiment: the worm gear 19 and worm 20 have self-locking properties, which can realize stepless adjustment and stable locking of the pitch angle, avoiding the problem of easy angle deviation in existing devices; the gearbox 22 protects the internal components and extends the service life; the operating handwheel 21 reduces the adjustment force and improves the ease of operation.

[0026] As a technical optimization of this utility model, both the support arm 10 and the hinge arm 12 are provided with pipe clamps 23 for constraining and fixing the delivery hose 5.

[0027] In this embodiment, the hose clamp 23 can prevent the hose from shifting or tangling due to water flow impact or external force pulling, ensuring stable water supply and avoiding the impact of hose deviation on the spraying accuracy of the nozzle 4.

[0028] As a technical optimization of this utility model, the locking pin 17 is a bolt with a handle, which extends through the side wall of the U-shaped clamp 14 into the limiting hole 16 and is locked by a wing nut.

[0029] In this embodiment: the handle facilitates quick insertion and removal of the locking pin 17, and the wing nut can be manually tightened without tools, achieving rapid positioning and stable locking of the nozzle's four circumferential angles, thus solving the defect of existing devices lacking precise positioning.

[0030] As a technical optimization of this utility model, the base 1 is provided with multiple through holes 24, and a ground anchor 25 is inserted into the through holes 24.

[0031] In this embodiment, the ground anchor 25 is inserted into the ground through the through hole 24 to firmly fix the device to the garden site, preventing the device from tipping over or shifting due to water flow or wind, thus improving the overall stability.

[0032] As a technical optimization of this utility model, the nozzle 4 is a pressure-compensated nozzle.

[0033] In this embodiment, the pressure-compensated sprinkler head can automatically adjust the water flow rate according to changes in water supply pressure, ensuring consistent spray uniformity at different locations and under different pressures, and avoiding local over- or under-watering caused by pressure fluctuations.

[0034] Working principle and usage process of this utility model: Place the base 1 in the garden area to be sprayed. Pass the ground anchor 25 through the through hole 24 on the base 1 and tap the top of the ground anchor 25 to insert it into the ground, ensuring a stable connection between the base 1 and the ground to prevent the device from shifting. According to the distribution direction of the plants to be sprayed, push the rotating seat 7 to rotate around the mounting platform 6. When the nozzle 4 is aligned with the target plant area, hold the top ring 18 of the pin 9 and insert the pin 9 into the corresponding insertion hole 8 of the rotating seat 7 and the mounting platform 6 to complete the horizontal positioning. Rotate the operating handwheel 21 of the worm gear assembly 13. The handwheel drives the worm 20 to rotate, and the worm 20 drives the meshing worm gear 19 to rotate. The worm gear 19 drives the horizontal rotating shaft 11 to rotate synchronously. The horizontal rotating shaft 11 drives the hinged arm 12 to rotate around it. Observe the pitch angle of the nozzle 4. Wait for the spray angle of the nozzle 4 to cover the target plant area. Once the target plant height is reached, stop turning the handwheel. For fine-tuning the circumferential spray direction: Hold the locking pin 17 handle, pull out the locking pin 17, and rotate the nozzle 4. When the nozzle 4 sprays towards the specific water-required area of ​​the plant, insert the locking pin 17 into the corresponding limiting hole 16 on the side wall of the U-shaped clamp 14 and the adjusting shaft 15, and tighten the wing nut to complete the circumferential positioning. Connect one end of the delivery hose 5 to the water source and the other end to the nozzle 4. Insert the hose clamp 23 into the pipe clamp 23 on the support arm 10 and the hinge arm 12 to prevent the hose from tangling. Turn on the water source switch; the pressure-compensated nozzle will spray water evenly under the water supply pressure, spraying the target plant. If other areas need to be sprayed, first turn off the water source, pull out the pin 9, push the rotating seat 7 to the new direction, and then reinsert the pin 9. Repeat the above steps to complete the position switching.
