Description

Technical Field

[0001] This invention relates to the field of garden care and maintenance technology, and in particular to a garden care and maintenance device. Background Technology

[0002] As the area of ​​urban parks and green spaces continues to expand, the workload of daily maintenance of park vegetation continues to increase. Pruning, shaping, and watering are the core operational links for maintaining the growth of park vegetation and ensuring the landscape effect.

[0003] Currently, garden maintenance operations generally use single-function, modular equipment. Pruning is mostly done manually using handheld chainsaws or hedge trimmers, which is labor-intensive and limits the working height. Irrigation often relies on large water trucks or manual backpack sprayers. Water trucks have difficulty entering narrow garden paths and shrubbery areas, and backpack equipment has limited water storage capacity, requiring frequent refills. Overall, the operation efficiency is low. Furthermore, irrigation nozzles are mostly fixed, with a fixed and unadjustable spraying range. This makes it impossible to flexibly adjust the coverage area according to the vegetation distribution, which can easily lead to irrigation blind spots or water waste, resulting in poor maintenance effects. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a garden care and maintenance device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a garden care and maintenance device, comprising a first frame and a second frame, both the first and second frames being equipped with wheels and auxiliary wheels, the second frame being equipped with a handrail, and a clamping device for clamping a water tank. The second frame and the first frame are spliced ​​together by means of a splicing device. The first frame is equipped with a support column, and the support column is equipped with an adjustment device. The adjustment device is equipped with an electric saw and a spraying device. The adjustment device is used to adjust the electric saw or the spraying device to be close to the vegetation. The electric saw is used to prune the vegetation, and the spraying device is used to irrigate the vegetation.

[0006] The effects achieved by the above components are as follows: the device can be flexibly combined and disassembled through the splicing double frame structure, the device shape can be adjusted according to different operation scenarios of garden maintenance, and the dual functions of vegetation pruning and watering are integrated. With the adjustment device, it can be adapted to vegetation operations in different locations, effectively improving the versatility of garden maintenance operations and overall operation efficiency.

[0007] Preferably, the clamping device is equipped with a worm gear, which is rotatably connected to the bottom of the first frame via a shaft. A turntable is mounted on the shaft, and a worm gear is rotatably connected to the first frame to drive the worm gear and rotate the turntable. The first frame has sliding grooves on both sides of the shaft, and a slider is slidably connected in the groove. A clamping plate is mounted on the top of the slider. Traction plates are symmetrically hinged to the turntable, and the end of the traction plate away from the turntable is hinged to the slider. As the turntable rotates with the worm gear, the traction plate drives the clamping plates on the slider to move closer or further apart along the groove to fit against the surface of the water tank.

[0008] The above-mentioned components achieve the following effects: the self-locking transmission structure of the worm gear drives the opening and closing of the clamping plate, which can stably clamp water tanks of different sizes. The clamping process is uniform in force and the locking is reliable, making it difficult to loosen or displace. The water tank can be clamped and disassembled simply by rotating the worm gear, which is easy to operate and effectively improves the stability of water tank installation and disassembly efficiency.

[0009] Preferably, the splicing device is provided with two limiting plates, a hinge shaft and a triangular block. The two limiting plates rotate relative to each other by means of the hinge shaft. Several intersecting stepped grooves are opened between the two limiting plates. A guide slope is provided at the end of each limiting plate away from the hinge shaft. The triangular block is located in any stepped groove between the two limiting plates.

[0010] The above components achieve the following effects: the frame is positioned by the interlocking structure of the stepped groove and the triangular block; different stepped groove positions can be selected to adjust the splicing distance between the two frames to adapt to different work space requirements; the guide slope can guide the triangular block to slide smoothly between the limiting plates, reducing the alignment difficulty of the splicing operation.

[0011] Preferably, a spring connects the two limiting plates, pushing the second frame closer to the first frame. The guide slopes of the two limiting plates on the first frame contact the triangular block. The triangular block slides along the guide slopes of the two limiting plates and squeezes the two limiting plates to rotate via the hinge shaft. At this time, the spring is compressed, and the triangular block continues to slide along the stepped groove between the two separate limiting plates until the first frame and the second frame are in contact. When the triangular block is exactly in a certain stepped groove, the spring's rebound force causes the two limiting plates to rotate and reset via the hinge shaft. Thus, the triangular block is exactly in the stepped groove and is limited, thereby enabling the first frame and the second frame to be successfully spliced.

[0012] The aforementioned components achieve the following effects: the limit plate automatically resets and locks by utilizing the spring's rebound force. During assembly, simply pushing the frame completes the automatic locking and fixing, eliminating the need for additional manual locking operations. This significantly improves the ease of frame assembly. At the same time, the spring's tension ensures the reliability of the assembly connection, preventing accidental separation of the frame during operation.

[0013] Preferably, the water tank is provided with a water inlet, the water tank is equipped with a water pump, and the output end of the water pump is connected to a water delivery pipe.

[0014] The above components achieve the following effects: the built-in water pump in the water tank, together with the water delivery pipe, provides a continuous and stable water supply to the spraying device; the water inlet facilitates quick replenishment of the water source, ensuring continuous irrigation operations; and the integrated water supply design eliminates the need for external long pipelines, improving the flexibility and convenience of mobile operation of the device.

[0015] Preferably, the support column is an I-beam, the adjustment device has an assembly plate, and connecting shafts are installed at both ends of one side of the assembly plate. A first guide wheel is installed on the connecting shaft for sliding within the grooves on both sides of the support column. A first connecting plate is connected between the two connecting shafts. A first motor is mounted on the support column, and the output shaft of the first motor is connected to a threaded rod via a coupling. The threaded rod is threadedly connected to the first connecting plate. Second guide wheels are rotatably connected at both ends of the other side of the first connecting plate. A second connecting plate is connected between the four second guide wheels. A rack is installed on one side of the second connecting plate. A rotating rod is rotatably connected to the support column, and a gear is installed on the rotating rod for meshing with the rack to drive the second connecting plate to slide between the second guide wheels. A rotating shaft is rotatably connected to one end of the second connecting plate, and its rotation angle is controlled by bolts. An electric saw is mounted on the rotating shaft, and a handle is installed on the rotating shaft for operating the rotating shaft to rotate and drive the electric saw to adjust its angle of contact with the vegetation. The other end of the second connecting plate is connected to a spraying device.

[0016] The effects achieved by the above components are as follows: the height of the working parts can be adjusted through the threaded rod transmission, the horizontal feed can be adjusted through the gear and rack transmission, and the working angle of the chainsaw can be flexibly adjusted with the rotating shaft to achieve multi-dimensional position adjustment. It can adapt to the pruning and watering needs of vegetation of different heights and shapes. The guide wheel structure can ensure the smooth and stable adjustment process and improve the adjustment accuracy of the working position.

[0017] Preferably, the spraying device includes a support plate, a clamping unit, a swinging unit, and a watering unit. The swinging unit is installed on the support plate. The clamping unit is used to clamp and fix the watering unit. The swinging unit is used to drive the clamping unit to swing and control the watering range of the watering unit. The watering unit is connected to the water delivery pipe of the water pump.

[0018] The effects achieved by the above components are as follows: the spraying device adopts a modular design, which is divided into three independent functional units: clamping, swinging and watering. This facilitates the individual maintenance and replacement of each unit. The swinging unit can drive the watering unit to swing back and forth to expand the irrigation coverage area. The clamping unit can fix the working posture of the watering unit, effectively improving the uniformity of irrigation operations and the coverage area.

[0019] Preferably, the watering unit includes an installation strip, which is mounted on the side wall of the support plate by means of a spring pin. Several locking blocks are installed on the installation strip, and a delivery pipe is locked onto each of the locking blocks. The delivery pipe is connected to a water supply pipe, and several solenoid valves are connected to the delivery pipe. Each solenoid valve is equipped with a gooseneck tube, and a nozzle is connected to the end of the gooseneck tube.

[0020] The effects achieved by the above components are as follows: the mounting strip can be quickly disassembled and assembled through the spring pin, which facilitates later maintenance and replacement operations; multiple independent solenoid valves can control the on and off of the corresponding nozzles respectively; and with the gooseneck tube that can be bent and shaped at will, the orientation and position of the nozzles can be flexibly adjusted to accurately control the irrigation area and water output, and adapt to the differentiated water replenishment needs of different vegetation.

[0021] Preferably, the clamping unit includes an electric actuator, the support plate has a strip groove, a slide bar is slidably connected in the strip groove, the electric actuator is mounted on the support plate to drive the slide bar to slide, a plurality of protrusions are mounted on the slide bar, a plurality of sets of rotating wheels are mounted on the support plate, each set of wheels consists of two wheels, each set of two wheels is fitted with meshing teeth, each set of two wheels is fitted with symmetrical clamping arms for clamping a single solenoid valve, one of the wheels in the set of wheels is fitted with a limiting plate, the limiting plate has a limiting groove, and the protrusions slide in the limiting groove.

[0022] The aforementioned components achieve the following effects: by driving a slide bar through a single electric actuator to synchronously open and close multiple sets of rotating wheel clamping arms, multiple solenoid valves and gooseneck tubes can be clamped and fixed at the same time. The transmission structure is compact, and the synchronicity of the actions of each set of clamping arms is good. It can stably lock the working angle of the gooseneck tube and avoid the nozzle from shifting during the watering process, thus affecting the watering accuracy and effect.

[0023] Preferably, the swing unit includes a connecting frame, which is mounted on a support plate. A rotating rod is rotatably connected to the connecting frame, and the end of the rotating rod away from the connecting frame is connected to the support plate. A second motor is mounted on the connecting frame, and the output shaft of the second motor is connected to a rotating disk via a coupling. Connecting rings are symmetrically mounted on the rotating rod, and extension plates are mounted on both connecting rings. A connecting column is connected between the opposite sides of the two extension plates, and a slip ring is slidably connected to the connecting column. An insert rod is mounted on the slip ring and slides through the eccentric position of the rotating disk.

[0024] The effect achieved by the above components is as follows: the crank-slider structure with eccentric rotating disk and slip ring connecting rod converts the circumferential rotation of the motor into the reciprocating swing motion of the bearing plate. The swing amplitude is uniform and the operation is stable, which can continuously expand the coverage area of ​​the irrigation operation, effectively improve the irrigation operation efficiency per unit time, and reduce the frequency of manual adjustment of the sprinkler head.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, a split-type double-frame structure is adopted, which can be flexibly spliced ​​and disassembled according to the work scenario. In the spliced ​​state, a large-capacity water tank can be carried to carry out continuous large-area maintenance work. After disassembly, the passage volume of the device can be reduced, which can be adapted to work in restricted spaces such as narrow walkways and bush gaps, effectively improving the device's scene adaptability. The splicing device adopts a structure of guide slope introduction, stepped groove engagement and spring automatic locking, which can achieve rapid splicing without auxiliary tools. The connection is stable and reliable, and the frame is not easy to separate during operation.

[0026] 2. In this invention, the water tank is clamped and fixed by a worm gear drive clamping device. The self-locking characteristic of the worm gear can achieve a continuous and stable clamping effect. The water tank is not easy to loosen or shift during device movement and operation. At the same time, it can be adapted to water tanks of different specifications and sizes to meet the water storage needs of different operation durations. Compared with the traditional strap or bolt fixing method, the water tank can be clamped and disassembled by simply rotating the worm gear. The operation is simple and labor-saving, which greatly improves the efficiency of water tank replacement and maintenance.

[0027] 3. In this invention, the adjustment device integrates vertical lifting and horizontal feed dual-dimensional adjustment functions. Combined with a rotatable and adjustable electric saw, it can flexibly adjust the height, horizontal distance, and working angle of the working parts, covering the maintenance needs of various vegetation types from low hedges to medium and high shrubs. It can complete the pruning and watering of vegetation of different sizes without changing the working equipment. Multiple sets of guide wheels, combined with the transmission structure of threaded rods and gear racks, ensure a smooth and stable adjustment process with high position control accuracy, effectively guaranteeing the pruning shaping effect and watering precision.

[0028] 4. In this invention, the spraying device adopts a modular multi-nozzle independent control structure. The spraying direction and angle of each nozzle can be flexibly adjusted through the bendable and shaped gooseneck tube. With the independent on / off solenoid valve, the irrigation area and water output can be precisely controlled according to the vegetation distribution, adapting to the differentiated water replenishment needs of different vegetation. The clamping unit can simultaneously lock the working posture of multiple sets of gooseneck tubes to avoid water pressure backflow causing nozzle displacement and maintain stable irrigation accuracy. The swing unit drives the nozzle as a whole to swing back and forth through the eccentric turntable linkage structure, which can effectively expand the irrigation coverage area of ​​a single set of nozzles, improve irrigation uniformity, reduce the frequency of device movement, and improve irrigation efficiency.

[0029] 5. In this invention, vegetation pruning and watering maintenance functions are integrated into the same mobile vehicle frame. Both maintenance tasks can be completed simultaneously with a single push, eliminating the need to carry multiple sets of independent equipment. This effectively reduces the workload of maintenance personnel, simplifies the operation process of garden maintenance, significantly improves the overall efficiency and quality of daily garden care and maintenance, and reduces the labor intensity of manual maintenance.

The upper part of the second frame 2 is equipped with a clamping device 5, which is used to detachably clamp and fix the water tank 7. A splicing device 6 is set between the adjacent ends of the second frame 2 and the first frame 1. The first frame 1 and the second frame 2 can be quickly spliced ​​and disassembled with the help of the splicing device 6. A support column 8 is vertically fixed on the top surface of the first frame 1. An adjustment device 9 is slidably mounted on the support column 8. An electric saw 10 and a spraying device 11 are respectively installed on the adjustment device 9. The adjustment device 9 can drive the electric saw 10 and the spraying device 11 to rise and fall along the support column 8 and to feed in the horizontal direction, thereby adjusting the relative position between the electric saw 10 or the spraying device 11 and the vegetation.

The upper end of the shaft passes through the plate of the second frame 2 and is fixedly connected to the center of the turntable 52. The worm 54 is rotatably mounted on the bottom of the second frame 2. The rod of the worm 54 meshes with the teeth of the worm gear 51. Rotating the worm 54 drives the worm gear 51 to drive the shaft and the turntable 52 to rotate synchronously. Two parallel grooves are provided on the plate of the second frame 2, corresponding to the two sides of the axle. The length of the two grooves extends radially along the turntable 52. A slider 55 is slidably embedded in each groove. The slider 55 can slide back and forth along the length of the groove. The top of each slider 55 extends upward out of the groove and is fixed with a clamping plate 56. The opposing surfaces of the two clamping plates 56 can be attached to the outer wall of the water tank 7. Two traction plates 53 are symmetrically hinged to the edge of the turntable 52. The ends of the two traction plates 53 away from the turntable 52 are respectively hinged to the bottom of the corresponding slider 55. When the turntable 52 rotates with the worm gear 51, the two traction plates 53 can pull the sliders 55 on both sides to slide synchronously along the groove, thereby driving the two clamping plates 56 to move closer to each other to clamp the water tank 7, or to move away from each other to release the water tank 7, thus completing the clamping and disassembly of the water tank 7.

[0034] The splicing device 6 includes two limiting plates 62, a hinge shaft 61, a triangular block 66, and a spring 63. One end of the two limiting plates 62 is rotatably connected to each other via the hinge shaft 61.

Several stepped grooves 64 are formed on the inner sidewalls of the two limiting plates 62, and the stepped grooves 64 on the two limiting plates 62 are arranged alternately to form multiple sets of locking groove structures that can be engaged and positioned. The free ends of the two limiting plates 62 away from the hinge shaft 61 are provided with outwardly inclined guide slopes 65, and the two guide slopes 65 together form an inlet opening that is wider on the outside and narrower on the inside. The triangular block 66 is fixedly installed on the end face of the second frame 2 facing the first frame 1, with the tip of the triangular block 66 facing the limiting plate 62. A spring 63 is connected between the outer walls of the two limiting plates 62. The two ends of the spring 63 are fixed to the outer walls of the two limiting plates 62 respectively. Under normal conditions, the spring 63 pulls the two limiting plates 62 to keep them closed.

[0035] The water tank 7 adopts a hollow, sealed box structure. The top of the water tank 7 has a water inlet, through which operators can add maintenance water to the water tank 7. A water pump is fixedly installed on the bottom surface inside the water tank 7. The output end of the water pump is connected to a water delivery pipe. The outlet end of the water delivery pipe extends upwards outside the water tank 7 and is connected to the water inlet of the spraying device 11. After the water pump is started, it can pressurize and deliver the water inside the water tank 7 to the spraying device 11.

[0036] The support column 8 is made of I-beam profile, with both sides of the support column 8 recessed inward to form guide grooves.

The threaded rod 94 is arranged vertically along the length of the support column 8. The rod body of the threaded rod 94 passes through the No. 1 connecting plate 93 and forms a threaded transmission engagement with the No. 1 connecting plate 93. When the No. 1 motor 95 drives the threaded rod 94 to rotate, it can drive the No. 1 connecting plate 93 and the assembly plate 91 to move up and down along the support column 8 as a whole.

[0037] On the side of the assembly plate 91 away from the support column 8, two guide wheels 96 are rotatably mounted at both the top and bottom. Two guide wheels 96 on the same side are arranged vertically. A connecting plate 97 is clamped between the four guide wheels 96, and the connecting plate 97 can slide back and forth horizontally along the limit of the guide wheels 96. A rack 98 is fixedly mounted on the side wall of the connecting plate 97, and the length direction of the rack 98 is consistent with the sliding direction of the connecting plate 97. A rotating rod 910 is rotatably mounted on the side of the support column 8. A gear 99 is fixedly mounted on the rod of the rotating rod 910. The teeth of the gear 99 mesh with the rack 98. Rotating the rotating rod 910 can drive the gear 99 to rotate, which in turn drives the connecting plate 97 to feed or retract horizontally through the rack 98. One end of the second connecting plate 97 is rotatably connected to a rotating shaft. A locking bolt is provided on the shaft. Tightening the locking bolt can fix the rotation angle of the rotating shaft. The electric saw 10 is fixedly installed at the end of the rotating shaft. A handle 101 is fixed on the side of the rotating shaft. The operator can operate the rotating shaft by holding the handle 101, thereby adjusting the working tilt angle of the electric saw 10. The other end of the second connecting plate 97 is fixedly connected to the spraying device 11.

[0038] The spraying device 11 includes a support plate 111, a clamping unit 112, a swinging unit 113, and a watering unit 114. The support plate 111 serves as the mounting base for the spraying device 11.

A strip-shaped groove is formed on the surface of the support plate 111, the length direction of which is consistent with the length direction of the mounting strip 1141. The slide bar 1122 is slidably embedded in the strip-shaped groove and can reciprocate along the length direction of the groove. The electric actuator 1121 is fixedly mounted on the surface of the support plate 111, and the output rod end of the electric actuator 1121 is fixedly connected to one end of the slide bar 1122. The extension and retraction of the electric actuator 1121 can drive the slide bar 1122 to slide along the strip-shaped groove. Several protruding posts are fixed at intervals on the top surface of the slide bar 1122. A set of rotating wheels 1124 is mounted on the surface of the support plate 111 corresponding to the position of each solenoid valve 1145. Each set of rotating wheels 1124 includes two rotating wheels 1124 arranged side by side. Both rotating wheels 1124 are rotatably connected to the support plate 111. The wheel bodies of both rotating wheels 1124 are fixed with meshing teeth 1128. The two rotating wheels 1124 are driven by meshing with each other through the meshing teeth 1128. A clamping arm 1125 is fixed on each rotating wheel 1124. The two clamping arms 1125 in the same set are arranged symmetrically. When the two rotating wheels 1124 rotate synchronously in opposite directions, they can drive the two clamping arms 1125 to move closer to each other and clamp onto the outer wall of the solenoid valve 1145, or move away from each other and release the solenoid valve 1145. A limiting plate 1126 is fixed on one of the rotating wheels 1124 in each group. A limiting groove 1127 is formed on the plate body of the limiting plate 1126. A corresponding protrusion on the slide bar 1122 is embedded in the limiting groove 1127. When the slide bar 1122 slides, the protrusion can slide along the inner wall of the limiting groove 1127 and drive the limiting plate 1126 and the rotating wheel 1124 to rotate synchronously.

[0041] The swing unit 113 includes a connecting frame 1131, a second motor 1132, a rotating disk 1133, a slip ring 1134, a connecting ring 1135, a connecting column 1136, and a rotating rod 1137.

[0042] Working principle: Before carrying out garden maintenance work, the first frame 1 and the second frame 2 are assembled. The operator holds the handle 4 and pushes the second frame 2 closer to the first frame 1. The triangular block 66 at the end of the second frame 2 gradually approaches the two limiting plates 62 at the end of the first frame 1. The tip of the triangular block 66 first contacts the guide slope 65 at the front end of the two limiting plates 62. As the second frame 2 continues to advance, the triangular block 66 slides inward along the slope of the guide slope 65, while squeezing the two limiting plates 62 to both sides, causing the two limiting plates 62 to rotate outward around the hinge axis 61 and open. At this time, the spring 63 connected between the two limiting plates 62 is stretched and stores force. Triangular block 66 slides inward along the gap between the two limiting plates 62, passing through different positions of stepped groove 64 in sequence. When the end faces of frame 1 and frame 2 are in place, triangular block 66 is inserted into the corresponding stepped groove 64. At this time, spring 63 retracts and pulls the two limiting plates 62 to rotate and reset around the hinge shaft 61. Triangular block 66 is limited in the slot of stepped groove 64 and cannot be removed. This completes the rapid splicing of the two frames. The operator can then hold the handle 4 and push the whole device along the garden path to the designated work position to carry out the corresponding maintenance work.

[0043] When installing and fixing the water tank 7, place the water tank 7 between the two clamping plates 56 of the second frame 2. Rotate the worm gear 54 to drive the meshing worm wheel 51 to rotate. The worm wheel 51 drives the turntable 52 to rotate synchronously through the shaft. During the rotation of the turntable 52, the two traction plates 53 hinged to the edge of the turntable deflect synchronously with the turntable 52, respectively pulling the sliders 55 on both sides to slide along the slide groove towards the center of the turntable 52. This causes the two clamping plates 56 to move closer to each other synchronously until the inner walls of the two clamping plates 56 are tightly attached to the outer walls of the two sides of the water tank 7. With the help of the self-locking characteristic of the worm gear transmission, the turntable 52 cannot drive the worm wheel 51 to rotate in the opposite direction under the action of external force. Therefore, the clamping plates 56 can stably clamp the water tank 7 and will not loosen due to the movement of the device or the vibration of the operation. When the water tank 7 needs to be disassembled for cleaning or maintenance, the worm gear 54 can be rotated in the opposite direction to move the two clamping plates 56 away from each other. After the water tank 7 is released, it can be removed from the second frame 2.

[0044] When performing vegetation pruning or watering operations, first adjust the vertical position of the working components according to the height of the vegetation to be pruned. Start the first motor 95 to drive the threaded rod 94 to rotate. The threaded rod 94 and the first connecting plate 93 form a threaded transmission, converting the rotational motion into linear motion. This drives the first connecting plate 93, the assembly plate 91, and all components on the assembly plate 91 to rise and fall as a whole along the support column 8. During the rising and falling process, the first guide wheel 92 rolls along the guide groove of the support column 8, providing guidance and support for the rising and falling process, ensuring a smooth and unobstructed process. After the working components have risen and fallen to the appropriate working height, rotate the rotating rod 910 to drive the gear 99 to rotate. The gear 99 meshes with the rack 98 to drive the second connecting plate 97 to move horizontally towards the vegetation along the limit of the second guide wheel 96, driving the electric saw 10 or the spraying device 11 to approach the vegetation to be pruned. When performing pruning operations, loosen the locking bolt of the rotating shaft, hold the handle 101 to rotate the rotating shaft, adjust the tilt angle of the chainsaw 10 to match the growth angle of the branches and pruning needs, tighten the locking bolt to fix the angle after adjustment, and start the chainsaw 10 to prune the vegetation branches.

[0045] When watering, start the water pump in the water tank 7. The water pump pressurizes the water in the water tank 7 and delivers it to the delivery pipe 1144 through the water pipe. The operator can open the corresponding solenoid valve 1145 according to the watering area and the water demand of the vegetation. The water enters the gooseneck pipe 1146 through the solenoid valve 1145 and is sprayed out from the nozzle at the end to water and maintain the vegetation. Before operation, the gooseneck tube 1146 can be bent in advance to adjust the orientation and spraying angle of each nozzle to adapt to the irrigation needs of vegetation in different locations. After the angle adjustment is completed, the electric actuator 1121 is activated. The output rod of the electric actuator 1121 extends and pushes the slide bar 1122 to slide along the strip groove. The protrusion on the slide bar 1122 slides along the limiting groove 1127 of the limiting plate 1126, causing the limiting plate 1126 and the corresponding rotating wheel 1124 to rotate around the axis. The rotating wheel 1124 drives another rotating wheel 1124 to rotate synchronously in the opposite direction through the meshing teeth 1128, thereby causing the two clamping arms 1125 to move closer to each other and clamp the outer wall of the corresponding solenoid valve 1145, thereby fixing the posture of the gooseneck tube 1146 and the nozzle, avoiding the nozzle displacement caused by water pressure backflow during spraying, and ensuring accurate irrigation position.

[0046] When it is necessary to expand the irrigation coverage of a single set of sprinklers, the second motor 1132 is started to drive the rotating disk 1133 to rotate at a uniform speed. The insert rod at the eccentric position of the rotating disk 1133 moves in a circular motion synchronously with the rotating disk 1133. At the same time, the insert rod drives the slip ring 1134 to slide back and forth along the rod of the connecting column 1136. Then, through the connecting column 1136 and the connecting rings 1135 on both sides, the rotating rod 1137 is driven to swing back and forth around the connecting frame 1131. The rotating rod 1137 drives the bearing plate 111 and all the sprinklers to swing back and forth synchronously, so that the spraying area of ​​the sprinklers forms a continuous fan-shaped coverage area, thereby expanding the irrigation area of ​​a single set of sprinklers, improving the efficiency and uniformity of irrigation operations, and completing the watering and maintenance of large areas of vegetation without frequent movement of the device.
