Description

Technical Field

[0001] This invention relates to the field of irrigation devices, and more particularly to a water-saving irrigation device for landscaping projects. Background Technology

[0002] Landscape greening refers to the creation of a beautiful natural environment and recreational area in a certain region by using engineering technology and artistic means to modify the terrain, plant trees and flowers, construct buildings, and arrange garden paths. This is called a garden. Gardens include courtyards, residential gardens, small parks, gardens, parks, botanical gardens, zoos, etc. With the development of landscape architecture, it also includes forest parks, scenic spots, nature reserves or national park tourist areas, and resorts. Irrigation devices are needed in the process of landscaping. However, the common irrigation method is to set up irrigation wells in the garden and irrigate directly to the ground through the well plugs. This irrigation has no direction or purpose and wastes water. Although there are existing mobile irrigation devices that can save water by moving to a designated location to water, the nozzles of the existing mobile irrigation devices are exposed to the outside for a long time, which is not convenient to store and protect, and it is also not convenient to adjust the overall height. Therefore, we propose a water-saving irrigation device for landscaping projects. Summary of the Invention

[0003] Purpose of the Invention: Another purpose of this invention is to provide a water-saving irrigation device for landscaping projects, which solves the shortcomings of existing mobile irrigation devices where the nozzles are exposed for a long time, making them inconvenient to store and protect, and the overall height is difficult to adjust. By setting a retractable nozzle structure and a height adjustment mechanism, the nozzles can be effectively stored and protected when not in use, extending their service life. At the same time, the overall height of the irrigation device can be flexibly adjusted according to the height requirements of different plants in the garden, improving the applicability and ease of use of the irrigation device.

[0004] Technical solution: A water-saving irrigation device for landscaping projects, including a spraying mechanism, wherein a height adjustment mechanism is provided below the spraying mechanism; The spraying mechanism includes a water storage tank, and a mounting box is bolted to the top of the water storage tank. A motor is fixedly connected inside the mounting box, and a spray head is fixedly connected to the top of the output shaft of the motor. Both sides of the mounting box and above the water storage tank are fixedly connected to L-shaped brackets. Each of the two L-shaped brackets is rotatably connected to a screw via a pivot. Each of the two screws is fixedly connected to a gear at its opposite ends. An L-shaped bracket is threaded onto the outer wall of each screw. Each of the two L-shaped brackets is rotatably connected to a shaft via a pivot at its inner ends. An adapter is fixedly connected to the outer wall of each shaft. Protective covers are fixedly connected to the opposite ends of each adapter, located outside the nozzle. Gears are fixedly connected to the left and right ends of each shaft. A rack is fixedly connected to both sides of each L-shaped bracket, and the rack is compatible with the gear.

[0005] Furthermore, a water pump is fixedly connected to the rear surface of the water storage tank, the input end of the water pump is fixedly connected to the water storage tank, and a flexible hose is fixedly connected between the output end of the water pump and the nozzle.

[0006] Furthermore, a cover plate is installed on the right side of the mounting box via bolts.

[0007] Furthermore, torsion springs are provided on both sides of the outer wall of the shaft located on both sides of the adapter, and the two ends of the torsion springs are fixedly connected to the inner opposite sides of the adapter and the L-shaped frame II, respectively.

[0008] Furthermore, a U-shaped guide seat is fixedly connected to the right side of the upper surface of the water storage tank. A screw rod two is rotatably connected to the inner side of the U-shaped guide seat via a rotating shaft. A U-shaped frame is threadedly connected to the outer side wall of the screw rod two. A toothed frame is fixedly connected to both ends of the left side of the U-shaped frame. The toothed frame meshes with the gear one. A gear three is fixedly connected to the right end of the screw rod two.

[0009] Furthermore, a handrail is fixedly connected to the upper surface of the U-shaped guide seat, a pull rod is slidably connected to the outer side wall of the handrail, and a rack is fixedly connected to the right side of the pull rod, the rack being meshed with the gear.

[0010] Furthermore, guide rods are fixedly connected to the opposite sides of the two L-shaped frames II, and the opposite ends of the two guide rods pass through the two L-shaped frames I respectively. Springs are fixedly connected to the opposite sides of the L-shaped frames I and L-shaped frames II and to the outer side walls of the guide rods.

[0011] Furthermore, the height adjustment mechanism includes a base plate, with two bearing seats fixedly connected to the front of the upper surface of the base plate. A bidirectional lead screw is rotatably connected between the two bearing seats via a rotating shaft. Two lead screw sleeves are threaded to the outer side wall of the bidirectional lead screw. Two fixed seats are fixedly connected to the rear of the upper surface of the base plate. A crossbar is fixedly connected between the two fixed seats. Two limiting sleeves are slidably connected to the outer side wall of the crossbar. Connecting heads are fixedly connected to the top of the limiting sleeves and the top of the lead screw sleeves. Inclined support rods are rotatably connected to the front and rear surfaces of the connecting heads via a rotating shaft. A concave part is rotatably connected to the top of two adjacent inclined support rods via a rotating shaft. The top of the concave part is fixedly connected to the bottom of the water storage tank.

[0012] Furthermore, the bottom of the base plate is fixedly connected with multiple casters.

[0013] Beneficial effects: This device solves the problem of the nozzles being easily damaged due to long-term exposure in existing mobile irrigation devices by using a retractable nozzle protection structure. When not in use, the protective cover can tightly wrap the nozzle, preventing it from being affected by external dust, gravel, rainwater, and collisions with tools during gardening operations, thus reducing the risk of nozzle clogging, shell wear, or internal parts corrosion. When irrigation is needed, the protective cover can be automatically flipped open through a simple mechanical transmission operation, without the need for manual disassembly or installation of protective components. This ensures the safe storage of the sprinkler head when it is not in use, without affecting the efficient operation of irrigation, significantly extending the overall service life of the sprinkler head and the entire irrigation device, and reducing equipment maintenance and replacement costs. To address the problem that existing irrigation devices are difficult to adjust in overall height and cannot adapt to the irrigation needs of plants of different heights, this device is equipped with a special height adjustment mechanism. By rotating the bidirectional screw, the relevant components can be linked together to change the angle of the tilting support, thereby driving the overall lifting and lowering of the spraying mechanism. Whether irrigating low lawns and flowers or taller shrubs and trees, operators can adjust the nozzles to the most suitable spraying height according to the actual height of the plants, ensuring that the water source can be accurately sprayed to the plant roots or leaf area, avoiding water waste caused by unsuitable height. This device achieves multi-dimensional improvements in water-saving performance, fully meeting the water-saving needs of landscaping projects. Firstly, by using a motor to drive the nozzles in a small-amplitude reciprocating oscillation spraying motion, compared to the single-point spraying or haphazard irrigation of traditional fixed nozzles, it can evenly cover a larger irrigation area, reducing the situation of excessive water concentration in some areas and insufficient irrigation in others, thus avoiding water waste. Secondly, the device can be moved to achieve precise irrigation of target areas, eliminating the need for indiscriminate watering of non-target areas like traditional irrigation wells, further reducing water consumption caused by ineffective irrigation.

Detailed Implementation

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example like Figures 1-5 As shown, a water-saving irrigation device for landscaping projects is provided, including a spraying mechanism 1; The spraying mechanism 1 includes a water storage tank 101. A mounting box 102 is installed on the top of the water storage tank 101 by bolts. A motor 103 is fixedly connected inside the mounting box 102. A nozzle 126 is fixedly connected to the top of the output shaft of the motor 103. L-shaped brackets 104 are fixedly connected to both sides of the mounting box 102 and above the water storage tank 101. Screws 105 are rotatably connected to the opposite sides of the two L-shaped brackets 104 via a rotating shaft. Gears 106 are fixedly connected to the opposite ends of the two screws 105. L-shaped brackets 107 are threadedly connected to the outer side of the screws 105. Shafts 108 are rotatably connected to the inner sides of the opposite ends of the two L-shaped brackets 107 via a rotating shaft. Adaptors 109 are fixedly connected to the outer side of the shafts 108. Protective covers 110 are fixedly connected to the opposite ends of the two adapters 109 and outside the nozzle 126. Gears 111 are fixedly connected to the left and right ends of the shafts 108. Racks 112 are fixedly connected to both sides of the L-shaped brackets 104. Racks 112 and gears 111 are compatible. A water pump 113 is fixedly connected to the rear surface of the water storage tank 101. The input end of the water pump 113 is fixedly connected to the water storage tank 101, and a hose 114 is fixedly connected between the output end of the water pump 113 and the nozzle 126. The cover plate 115 is installed on the right side of the mounting box 102 by means of bolts; The outer side wall of the shaft 108 is provided with torsion springs 127 on both sides of the adapter 109. The two ends of the torsion springs 127 are fixedly connected to the inner opposite sides of the adapter 109 and the L-shaped frame 107, respectively. A U-shaped guide seat 116 is fixedly connected to the right side of the upper surface of the water storage tank 101. A screw 117 is rotatably connected to the inner side of the U-shaped guide seat 116 via a rotating shaft. A U-shaped frame 118 is threadedly connected to the outer side wall of the screw 117. A gear frame 119 is fixedly connected to both ends of the left side of the U-shaped frame 118. The gear frame 119 meshes with a gear 106. A gear 120 is fixedly connected to the right end of the screw 117. A handrail 121 is fixedly connected to the upper surface of the U-shaped guide seat 116. A pull rod 122 is slidably connected to the outer side wall of the handrail 121. A rack 123 is fixedly connected to the right side of the pull rod 122. The rack 123 meshes with the gear 120. Guide rods 124 are fixedly connected to the opposite sides of the two L-shaped frames 107. The opposite ends of the two guide rods 124 pass through the two L-shaped frames 104 respectively. Springs 125 are fixedly connected to the opposite sides of the L-shaped frames 104 and L-shaped frames 107 and to the outer side of the guide rods 124. When the device is not in use, the two protective covers 110 are closed, enclosing the nozzle 126 inside for storage and protection. If the nozzle 126 needs to be deployed for irrigation, the operator stands next to the handrail 121, holds the handrail 121 with both hands to keep the device stable, and then pulls the lever 122. The lever 122 slides along the outer wall of the handrail 121. Since the rack 123 fixedly connected to the right side of the lever 122 meshes with the gear 120, the rightward movement of the rack 123 will drive the gear 120 to rotate, which in turn will drive the screw 117 fixedly connected to the gear 120 to rotate synchronously inside the U-shaped guide seat 116. When the screw 117 rotates, the U-shaped frame 118 threaded to its outer wall will move along the axial direction of the screw 117. The toothed frame 119 fixed at both ends on the left side of the U-shaped frame 118 will move synchronously. Since the toothed frame 119 meshes with the gear 106, the movement of the toothed frame 119 will drive the gear 106 to rotate, which in turn will drive the screw 105 fixedly connected to the gear 106 to rotate inside the L-shaped frame 104. When screw 105 rotates, L-shaped bracket 107 connected to its outer wall threadedly will move outward along the axis of screw 105 (the two L-shaped brackets 107 move in opposite directions synchronously). At this time, the guide rods 124 fixed on both sides of L-shaped bracket 107 will slide synchronously along the through hole of L-shaped bracket 104, which will guide the movement of L-shaped bracket 107. At the same time, the spring 125 between L-shaped bracket 104 and L-shaped bracket 107 is stretched (to provide elastic force for subsequent reset during storage). The large opening of the rotating groove of screw 105 facilitates the subsequent push and rebound of spring 125, making it a helical rod. When L-shaped frame 107 moves outward, the shaft 108 connected to it via a rotating shaft moves synchronously. The gears 111 fixed at both ends of shaft 108 mesh with the racks 112 fixed on both sides of L-shaped frame 104. Since rack 112 is fixed, gears 111 rotate as shaft 108 moves, which in turn drives shaft 108 and the adapter 109 fixed on the outer wall of shaft 108 to rotate synchronously. When adapter 109 rotates, the protective cover 110 fixed at its opposite end flips outward. At this time, the torsion springs 127 on both sides of adapter 109 on the outer wall of shaft 108 are twisted and stored. When L-shaped frame 107 moves to its maximum stroke, the protective cover 110 flips open completely, and the nozzle 126 is exposed and ready for irrigation. At this time, the pull rod 122 can be stopped. Once the sprinkler head 126 is deployed, the device can be started for irrigation. Open the inlet of the water storage tank 101 to ensure that the water storage tank 101 contains sufficient water. Then start the water pump 113 fixed on the rear surface of the water storage tank 101. When the water pump 113 is working, its input end draws water from the water storage tank 101 and delivers it to the nozzle 126 through the hose 114 at the output end. The water is sprayed out from the nozzle hole of the nozzle 126 to achieve initial irrigation. The motor 103, fixed inside the mounting box 102, is activated. The output shaft of the motor 103 drives the nozzle 126, fixed at the top, to reciprocate slightly (the reciprocating angle can be preset according to actual irrigation needs). The reciprocating motion of the nozzle 126 expands the irrigation range, allowing water to be sprayed evenly onto the target plant area, avoiding the problems of water concentration and waste in traditional irrigation methods, thus achieving water conservation. During irrigation, the operator can move the entire device by pushing the handle 121, in conjunction with the casters 211 at the bottom of the base plate 201, to irrigate different areas of the garden. After the operation is completed, the pull rod 122 is released. Under the return of the spring 125, all parts return to their original positions, the protective cover 110 closes again, and the nozzle 126 is protected.

[0018] like Figure 1 and Figure 6 As shown, a height adjustment mechanism 2 is provided below the spraying mechanism 1; The height adjustment mechanism 2 includes a base plate 201. Two bearing seats 202 are fixedly connected to the front of the upper surface of the base plate 201. A two-way lead screw 203 is rotatably connected between the two bearing seats 202 via a rotating shaft. Two lead screw sleeves 204 are threadedly connected to the outer side wall of the two-way lead screw 203. Two fixed seats 205 are fixedly connected to the rear of the upper surface of the base plate 201. A crossbar 206 is fixedly connected between the two fixed seats 205. Two limiting sleeves 207 are slidably connected to the outer side wall of the crossbar 206. Connecting heads 208 are fixedly connected to the top of the limiting sleeves 207 and the top of the lead screw sleeves 204. Inclined support rods 209 are rotatably connected to the front and rear surfaces of the connecting heads 208 via a rotating shaft. A concave part 210 is rotatably connected to the top of two adjacent inclined support rods 209 via a rotating shaft. The top of the concave part 210 is fixedly connected to the bottom of the water storage tank 101. The bottom of the base plate 201 is fixedly connected with multiple casters 211; The height adjustment mechanism 2 is used to adjust the overall height of the spraying mechanism 1 to adapt to the irrigation needs of plants of different heights in the garden. Its core is to drive the angle change of the inclined support rod 209 by rotating the bidirectional screw 203, thereby realizing the height adjustment of the water storage tank 101 (and the nozzle 126). The operator stands next to the base plate 201, holds one end of the double-acting screw 203 with both hands and rotates the double-acting screw 203. The double-acting screw 203 rotates between the two bearing seats 202, and the two screw sleeves 204 connected to the outer wall of the screw 203 will move relative to each other or in opposite directions along the axial direction of the double-acting screw 203. When the lead screw sleeve 204 moves, the connector 208 fixed at its top moves synchronously. The inclined support rod 209, which is rotatably connected to the front and rear surfaces of the connector 208 via a rotating shaft, changes angle accordingly. At the same time, the limiting sleeve 207, which is slidably connected to the outer wall of the crossbar 206 between the fixed seats 205 on the upper surface of the base plate 201, slides synchronously along the crossbar 206 as the angle of the inclined support rod 209 changes (serving a guiding and stabilizing function). When the two lead screw sleeves 204 approach each other, the angle between the inclined support rod 209 and the base plate 201 increases, and the concave part 210, which is rotatably connected to the top of the inclined support rod 209 via a rotating shaft, moves upward accordingly, thereby driving the water storage tank 101 (and the entire spraying mechanism 1) fixedly connected to the top of the concave part 210 to rise or fall.

[0019] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
