Description

Technical Field

[0001] This utility model relates to the field of sprinkler technology, specifically a ground-mounted swing sprinkler with adjustable nozzle angle. Background Technology

[0002] A ground-mounted swing sprinkler is a device used for irrigation and watering, typically in agriculture, horticulture, and landscaping. The base provides support and stability, allowing the sprinkler to remain balanced on the ground. Some bases may also have a fixing device to secure the sprinkler in a specific position, preventing it from moving during operation. The water outlet device, with its nozzles, is one of the core components of the sprinkler, responsible for spraying water into a mist or jet. The shape, size, and number of nozzles affect the spraying effect and range. Suitable for gardens, lawns, farmland, and other locations of various sizes, the appropriate model and spraying range can be selected according to needs.

[0003] Existing ground-mounted oscillating sprinklers typically use bolts to position the rotatable nozzles, thereby adjusting the overall pitch angle of the nozzles. While this allows for adjustment of the spray angle, it requires manual disassembly and adjustment, reducing the ease of adjustment. Utility Model Content

[0004] The purpose of this utility model is to provide a ground-mounted swing sprinkler with adjustable nozzle angle, in order to solve the problem mentioned in the background art that the rotating nozzle is generally positioned by bolts to adjust the pitch angle of the nozzle. Although the spray angle of the nozzle can be adjusted, it requires personnel to disassemble and adjust it, which reduces the convenience of adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ground-mounted swing sprinkler with adjustable nozzle angle, comprising a fixed mounting frame with a mounting groove on its surface, support bases mounted on the bottom surfaces of both sides of the mounting groove, two support columns fixedly connected to the upper surface of the support bases, a sprinkler head installed between the two support columns, a water inlet groove on the rear surface of the fixed mounting frame, two water guiding hoses fixedly connected to the bottom surface of the mounting groove, a linkage impeller mounted on the inner wall of the water inlet groove, an adjusting gear fixedly connected to the upper end of the shaft of the linkage impeller, a support slide plate mounted on the bottom surface of the mounting groove, a positioning tooth block fixedly connected to the lower inner surface of the support slide plate, an electric push rod fixedly connected to the upper surface of the support slide plate, and an angle adjustment mechanism provided at the output end of the electric push rod, which drives the limit connecting block to rise and fall through the electric push rod to facilitate the buffer slider to drive the steering block and the adjusting arm to rotate.

[0006] Preferably, the support base is rotatably connected to the fixed installation frame, and the support column is rotatably connected to the sprinkler head.

[0007] Using the above technical solution, the rotation of the support base allows the entire sprinkler to rotate horizontally, adapting to the irrigation needs of different areas; the rotation of the support column and the nozzle allows the nozzle to adjust its pitch angle vertically, expanding the water spraying coverage.

[0008] Preferably, the water inlet groove is connected to two water guiding hoses, and the two water guiding hoses are respectively connected to the sprinkler heads on both sides.

[0009] By adopting the above technical solution, the flexible hose connection reduces the number of rigid pipe interfaces, lowers the risk of water leakage, and allows the water path to remain open when the nozzle rotates, thus avoiding pipe breakage due to mechanical movement.

[0010] Preferably, the linkage impeller and the water inlet slot are rotatably connected, the adjusting gear has a missing tooth design, the supporting plate has an inverted concave design, the adjusting gear and the positioning tooth block are meshing, and the supporting plate and the mounting slot are slidingly connected.

[0011] By adopting the above technical solution, the tooth-missing design of the adjusting gear enables the supporting slide plate to achieve a periodic "sliding-pausing" motion, thereby driving the nozzle to swing left and right, simulating the trajectory of manual water spraying, and achieving more uniform coverage.

[0012] Preferably, the angle adjustment mechanism includes a limiting connecting block, which is fixedly connected to the output end of the electric push rod. A limiting slider is fixedly connected to the upper surface of the limiting connecting block. A groove is provided on the side surface of the limiting connecting block, and a buffer slider is installed on the inner wall of the groove. A steering block is provided on the side surface of the buffer slider, and an adjusting arm is installed on the surface of the steering block.

[0013] Using the above technical solution, the electric push rod directly drives the limit connecting block to rise and fall. By adjusting the rotating arm and linking the nozzle, the electric stepless adjustment of the nozzle pitch angle can be achieved without manual disassembly and assembly, thus improving convenience.

[0014] Preferably, the limiting slider is slidably connected to the fixed mounting structure, and rollers are provided at both ends of the limiting slider. The limiting connecting block is slidably connected to the limiting slider, and the limiting connecting block is slidably connected to the buffer slider. A spring is connected between the limiting connecting block and the buffer slider.

[0015] By adopting the above technical solution, the spring connection can absorb the impact force during the adjustment process, prevent damage to mechanical parts, and extend service life.

[0016] Preferably, the buffer slider and the steering block are rotatably connected, the steering block and the adjusting arm are rotatably connected, and one end of the adjusting arm is rotatably connected to one end of the sprinkler head.

[0017] By adopting the above technical solution, the multi-stage rotating connection allows the adjustable arm to adjust its posture in three-dimensional space, ensuring the flexibility and accuracy of nozzle angle adjustment.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the adjustable nozzle angle ground-mounted swing sprinkler:

[0019] 1. The electric push rod drives the angle adjustment mechanism, which can realize the electric stepless adjustment of the pitch angle of the sprinkler head. The linkage design of the limit connecting block, buffer slider and adjustment arm converts the linear motion of the electric push rod into the rotational motion of the sprinkler head. The angle adjustment can be completed with one button without the need for manual disassembly and assembly of bolts, which significantly improves the convenience of operation and solves the problem of low adjustment efficiency of traditional bolt positioning method. The roller design of the limit slider reduces friction, and the spring buffer structure can absorb the adjustment impact, avoid mechanical damage, and ensure long-term stable operation.

[0020] 2. The impeller in the water inlet slot is driven to rotate by the water flow. Through the meshing transmission of the toothed adjustment gear and the positioning gear block, it drives the support slide plate to slide back and forth. This process does not require an additional power source. It uses the energy of the water flow to realize the automatic left and right swing of the sprinkler, simulating the trajectory of manual watering, so that the spraying range is wider and more uniform. The intermittent transmission characteristics of the toothed gear can form a periodic action, further expanding the coverage area, reducing irrigation blind spots, and improving irrigation efficiency in various scenarios.

[0021] 3. The rotating connection between the support base and the fixed mounting bracket allows the sprinkler body to rotate horizontally, adapting to different terrain layout requirements. The rotating connection between the support column and the nozzle allows the nozzle to tilt vertically. Combined with the multi-stage rotating structure of the adjusting arm, the nozzle angle can be finely adjusted in three-dimensional space. The flexible connection design of the water guide hose ensures water flow while allowing the nozzle to rotate freely, avoiding the risk of leakage or breakage caused by rigid pipe connections. The rotational cooperation between the buffer slider and the steering block can adaptively compensate for installation errors, ensuring smooth and continuous movement of all components and enhancing the stability and adaptability of the device in complex environments.

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a ground-mounted swing sprinkler with adjustable nozzle angle, including a fixed mounting frame 1, a mounting slot 2, a support base 3, a support column 4, a sprinkler head 5, a water inlet slot 6, a water guide hose 7, a linkage impeller 8, an adjusting gear 9, a support slide plate 10, a positioning tooth block 11, an electric push rod 12, a limiting connecting block 13, a limiting slider 14, a buffer slider 15, a steering block 16, and an adjusting arm 17. The fixed mounting frame 1 has a mounting slot 2 on its surface, and the support base 3 is installed on the bottom surface of both sides of the mounting slot 2. The support base 3 is rotatably connected to the fixed mounting bracket 1, and the support column 4 is rotatably connected to the sprinkler head 5. Water enters from the water inlet slot 6 on the rear surface of the fixed mounting bracket 1 and is diverted to the sprinkler heads 5 on both sides through the water guide hose 7, so that the two sprinklers can supply water at the same time. The water flow impacts the linkage impeller 8 in the water inlet slot 6, causing it to rotate around the shaft. When the adjusting gear 9 rotates with the linkage impeller 8, it drives the support slide plate 10 to slide back and forth in the mounting slot 2, thereby driving the electric push rod 12 and the angle adjustment mechanism above to move left and right, so as to realize the automatic swing function of the sprinkler.

[0031] Two support columns 4 are fixedly connected to the upper surface of the support base 3. A sprinkler head 5 is installed between the two support columns 4.

The adjusting gear 9 and the positioning tooth block 1... 1. A meshing connection is formed, and the support slide plate 10 and the mounting slot 2 form a sliding connection. After the electric push rod 12 is energized, the output end drives the limit connecting block 13 to rise and fall vertically, so that the limit slider 14 on the upper surface of the limit connecting block 13 is slidably connected to the fixed mounting bracket 1, ensuring the stability of the lifting direction. The buffer slider 15 in the groove on the side surface of the limit connecting block 13 is connected to the limit connecting block 13 through a spring, which can absorb the impact force during the lifting process. When the limit connecting block 13 rises and falls, the buffer slider 15 drives the adjusting arm 17 to rotate through the steering block 16, and the adjusting arm 17 drives the sprinkler head 5 to rotate around the support column 4, so as to realize the adjustment of the pitch angle of the sprinkler head.

[0032] A support slide plate 10 is installed on the bottom surface of the mounting slot 2. A positioning tooth block 11 is fixedly connected to the inner surface of the lower end of the support slide plate 10. An electric push rod 12 is fixedly connected to the upper surface of the support slide plate 10. The angle adjustment mechanism includes a limiting connecting block 13, which is fixedly connected to the output end of the electric push rod 12. A limiting slider 14 is fixedly connected to the upper surface of the limiting connecting block 13. A groove is provided on the side surface of the limiting connecting block 13, and a buffer slider 15 is installed on the inner wall of the groove.

The two ends of the adjusting arm 17 are rotatably connected to the steering block 16 and the sprinkler head 5, respectively. The buffer slider 15 is rotatably connected to the steering block 16, forming a multi-stage rotation node. This design makes it easy to drive the rotation of the support column 4, the sprinkler head 5 and the support base 3 through the steering block 16 and the adjusting arm 17 when the limiting connecting block 13 slides.

[0033] The output end of the electric push rod 12 is equipped with an angle adjustment mechanism, which drives the limit connecting block 13 to rise and fall through the electric push rod 12, so that the buffer slider 15 can drive the steering block 16 and the adjusting arm 17 to rotate. The limit slider 14 is slidably connected to the fixed mounting bracket 1, and rollers are provided at both ends of the limit slider 14. The limit connecting block 13 is slidably connected to the limit slider 14, and the limit connecting block 13 is slidably connected to the buffer slider 15. A spring is connected between the limit connecting block 13 and the buffer slider 15.

The flexibility of the hose allows the sprinkler head to maintain water flow when adjusting the angle or swinging, avoiding leakage or breakage caused by mechanical movement of the rigid pipe connection.

[0034] Working principle: When using this adjustable nozzle angle ground-mounted swing sprinkler, water flows in from the water inlet slot 6 of the fixed mounting frame 1, and is diverted to the sprinkler head 5 through the water guide hose 7. At the same time, the impact linkage impeller 8 rotates, driving the adjusting gear 9 to mesh with the positioning gear block 11, causing the support slide plate 10 to slide back and forth. The support slide plate 10 drives the limit connecting block 13 and the limit slider 14 to slide. The limit connecting block 13 drives the support base 3, the support column 4 and the sprinkler head 5 to rotate through the buffer slider 15, the steering block 16 and the adjusting arm 17, realizing the automatic swing of the sprinkler head 5. The electric push rod 12 drives the limit connecting block 13 to rise and fall. The buffer slider 15 drives the steering block 16 and the adjusting arm 17 to rotate, thereby adjusting the pitch angle of the sprinkler head 5. The rotational connection between the support base 3 and the fixed mounting frame 1, and the rotational connection between the support column 4 and the sprinkler head 5, together with the multi-stage rotating components, realizes horizontal rotation and angle fine adjustment. The flexible hose 7 ensures water flow during movement, increasing the overall practicality.
