Description

Technical Field

[0001] This invention belongs to the field of garden equipment technology, and specifically relates to a garden green plant irrigation device. Background Technology

[0002] Garden irrigation is a technical measure to replenish the soil moisture needed for the growth of garden plants, thereby improving their growing conditions. It utilizes manual or mechanical methods in various forms of irrigation to replenish the soil moisture in garden green spaces and meet the water requirements of the plants.

[0003] Currently, Chinese patent CN221554208U, published on August 20, 2024, discloses a water spraying device for horticultural engineering with adjustable water volume. The device includes an operating platform with support frames fixed at both ends of the top. A capacity tank is fixed between the tops of the two support frames. A spraying assembly is located at the bottom of the capacity tank for rotating water spraying, improving the comprehensiveness of water spraying in horticultural engineering. Support components at the bottom of the operating platform facilitate stable fixation of the platform in the garden. The spraying assembly includes a rotating spray frame located at the top of the operating platform and the bottom of the capacity tank. A water outlet pipe is connected to the bottom of the capacity tank via a sealed bearing. The outer side of the water outlet pipe is connected to the inner wall of the rotating spray frame via two connecting pipes. Several evenly distributed nozzles are fixed on the outer wall of the rotating spray frame. A motor is fixed at the bottom of the operating platform, with its output shaft passing through the platform and fixedly connected to the bottom of the water outlet pipe, facilitating motor-driven rotation of the water outlet pipe.

[0004] This type of gardening sprinkler system with adjustable water volume uses a motor fixed at the bottom of the operating platform to drive the water outlet pipe to rotate, thereby achieving rotating water spraying; however, when watering, water can easily get into the motor located at the bottom of the operating platform, which can easily lead to motor damage. Summary of the Invention

[0005] The purpose of this invention is to provide a garden greening irrigation device that can help to stably achieve rotating water spray irrigation.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a garden greening irrigation device, comprising a water inlet hose connected to an urban water network, a base set on the ground, a spray pipe set on the base and connected to the water inlet hose, and a plurality of first nozzles set on the spray pipe for spraying water onto distant greening plants. A bracket is provided on one side of the base, and a support base is fixed to the upper end of the bracket. A water inlet pipe extending vertically and connected to the water inlet hose at its upper end is fixed on the support base. A booster pump is provided on the water inlet pipe. A disc-shaped water inlet tank is provided on the base. The water inlet tank has a side... The upper side is provided with an inlet sleeve for the lower end of the inlet pipe to be embedded. The lower side of the side of the inlet tank is provided with a rotating sleeve. The base is provided with a rotating shaft whose upper end is embedded in the rotating sleeve. The side of the inlet tank away from the inlet sleeve is provided with a spray pipe connected to the spray pipe. A central shaft is rotatably connected to the center of the inlet tank. A connecting plate is provided inside the inlet tank and around the central shaft. Multiple water wheel buckets are provided around the connecting plate to receive the water jet from the inlet sleeve. A first linkage assembly is provided between the base and the central shaft to drive the entire inlet tank to rotate through the rotation of the central shaft.

[0007] By adopting the above technical solution, when irrigation is carried out using the inlet hose, the water from the inlet hose first passes through the inlet pipe and enters the inlet sleeve of the inlet tank. Then, the booster pump on the inlet pipe pressurizes the water, and the pressurized high-speed water flow enters the inlet tank. Multiple water impellers are set around the connecting plate to receive the water flow sprayed from the inlet sleeve. Under the impact of the high-speed water flow, the water impellers around the connecting plate rotate, thereby driving the central shaft to rotate through the connecting plate and the multiple water impellers. At this time, the first linkage component set between the base and the central shaft drives the entire inlet tank to rotate through the rotation of the central shaft. Subsequently, the inlet tank drives the spray pipe to rotate around the rotating shaft, which ultimately helps to achieve stable rotating water spray irrigation.

[0008] A further configuration of the present invention is as follows: the first linkage component includes a first bevel gear disposed at one end of the central shaft and located outside the water inlet tank, a bearing seat disposed on the outer wall of the water inlet tank and located below the central shaft, a linkage shaft rotatably connected to the bearing seat, a second bevel gear disposed at the upper end of the linkage shaft and meshing with the first bevel gear, a movable gear disposed at the lower end of the linkage shaft, and a fixed gear disposed at the lower end of the rotating shaft and meshing with the movable gear.

[0009] By adopting the above technical solution, the rotation of the central shaft can drive the first bevel gear to rotate, and the first bevel gear can drive the linkage shaft to rotate through the second bevel gear. Subsequently, the linkage shaft can drive the movable gear to rotate. Since the movable gear meshes with the fixed gear, the movable gear can rotate around the circumference of the fixed gear, which can then drive the water inlet tank to rotate around the rotating shaft.

[0010] A further provision of the present invention includes: a piston sleeve disposed on the outer wall of the water inlet tank and located on the side of the water inlet tank; a piston block disposed inside the piston sleeve; a piston rod disposed on the piston block; a piston hole for the piston rod to pass through being opened at one end of the piston sleeve; a second nozzle for spraying water onto nearby green plants disposed at the end of the piston sleeve away from the piston hole; a connecting seat for connecting to the piston sleeve disposed on the outer wall of the water inlet tank; a water inlet hole communicating with the piston sleeve disposed inside the connecting seat; and a second linkage assembly for driving the piston rod to extend and retract through the rotation of the central shaft disposed on the outside of the water inlet tank.

[0011] By adopting the above technical solution, when the central shaft rotates, the second linkage component can drive the piston rod to extend and retract through the central shaft. When the piston rod drives the piston block to move towards the side closer to the second nozzle inside the piston sleeve, the water inside the piston sleeve can be squeezed out from the side of the second nozzle. Since the pressure generated by the piston block on the water inside the piston sleeve is limited, the water sprayed from the second nozzle has a relatively short range. At this time, the water can be sprayed and irrigated for nearby plants through the second nozzle. However, since the pressure generated by the water inside the nozzle is relatively large, the water sprayed from the first nozzle has a relatively long range. At this time, the water can be sprayed and irrigated for distant plants through the first nozzle. At the same time, when the piston rod drives the piston block to move away from the second nozzle inside the piston sleeve and passes the water inlet, the water in the water tank can be injected into the piston sleeve through the water inlet, thus facilitating the next spraying of the second nozzle.

[0012] A further configuration of the present invention is as follows: the second linkage component includes a rotating arm disposed at one end of the central shaft and located outside the water inlet tank, a drive column disposed at one end of the rotating arm away from the central shaft, and a long sleeve disposed at one end of the piston rod away from the piston block and into which the drive column is embedded. The long sleeve extends vertically, and the piston rod is also provided with a sealing block that fits against the inner wall of the piston sleeve and is used to block the water inlet hole.

[0013] By adopting the above technical solution, when the central shaft rotates, it can drive the rotating arm to rotate. Since the driving column of the rotating arm is embedded in the long sleeve and the long sleeve extends in the vertical direction, as the driving column rotates around the central shaft, the driving column can drive the piston rod to achieve telescopic movement through the long sleeve.

[0014] When the piston block moves towards the second nozzle within the piston sleeve, it needs to squeeze the water inside the sleeve. At this time, the piston block experiences significant damping force. This obstruction is transmitted to the central shaft via the long sleeve and rotating arm, hindering its rotation. Consequently, the rotation of the water wheel around the connecting plate is also obstructed, preventing it from rotating smoothly with the water entering the inlet sleeve. This sluggish rotation of the water wheel interferes with the flow rate of the water in the inlet tank, ultimately reducing the range of the water jet from the first nozzle. Simultaneously, when the piston block moves away from the second nozzle within the piston sleeve, due to… The sealing block fits against the inner wall of the piston sleeve and is used to block the water inlet hole. The reverse movement of the piston block no longer requires squeezing water and only needs to draw in outside air through the second nozzle. Therefore, the central axis can rotate relatively smoothly. Subsequently, the water wheel bucket can rotate smoothly with the water entering the water inlet sleeve. At this time, the water wheel bucket no longer interferes with the flow rate of the water in the water inlet tank, which will eventually make the water jet from the first nozzle have a longer range. At this time, the extension and retraction of the piston block can affect the range of the water jet from the first nozzle, causing the water jet range of the first nozzle to change from near to far. Ultimately, this will help the first nozzle to cover plants at various distances.

[0015] A further feature of the present invention is that the water inlet hole is elongated and its extension direction is parallel to the extension direction of the piston sleeve.

[0016] By adopting the above technical solution, and utilizing the elongated shape of the water inlet hole with its extension direction parallel to that of the piston sleeve, the water in the water tank can be stably filled to the entire piston sleeve.

[0017] A further provision of the present invention is that: a telescopic column is provided on the side of the long sleeve away from the piston rod, and a fixed seat connected to the outer wall of the nozzle is provided at the end of the telescopic column away from the long sleeve; and a corrugated hose is provided between the water spray pipe and the nozzle, with one end connected to the water spray pipe and the other end connected to the nozzle.

[0018] By adopting the above technical solution, when the long sleeve moves left and right under the drive of the drive column, the long sleeve can drive the spray pipe to move left and right through the telescopic column and the fixed seat. After the corrugated hose deforms arbitrarily, it ensures a stable connection between the spray pipe and the water spray pipe. At this time, the water flow sprayed from the first nozzle can move left and right while rotating around the rotating shaft, thereby increasing the coverage area of ​​the first nozzle irrigation, which is conducive to efficiently completing the irrigation of plants.

[0019] A further feature of the present invention is that a mounting base is provided on the outer wall of the water inlet tank on the side away from the piston sleeve, and a guide sleeve for the telescopic column to pass through is provided on the mounting base.

[0020] By adopting the above technical solution, the guide sleeve on the mounting base is used for the telescopic column to pass through. The guide sleeve can support and guide the telescopic column's extension and retraction, which is conducive to the stable extension and retraction of the telescopic column.

[0021] A further feature of the present invention is that: a bearing sleeve for embedding the end of the telescopic column is provided on the side of the long sleeve away from the piston rod; a spiral guide groove is provided on the telescopic column; and a guide column embedded in the guide groove is provided on the inner wall of the guide sleeve.

[0022] By adopting the above technical solution, when the telescopic column moves left and right within the guide sleeve, the end of the telescopic column is embedded in the bearing sleeve on the long sleeve, thus achieving a rotatable connection between the telescopic column and the long sleeve. Simultaneously, the telescopic column has a spiral guide groove, and the guide sleeve has a guide column embedded in the guide groove. Therefore, while moving left and right, the telescopic column can also deflect back and forth. The back and forth deflection of the telescopic column can drive the nozzle to swing up and down. At this time, the water jet from the first nozzle can rotate around the rotating axis and move left and right, while also swinging up and down, thereby further increasing the coverage area of ​​the first nozzle irrigation and ultimately facilitating efficient irrigation of plants.

[0023] The beneficial effects of this invention are as follows: When irrigation is carried out using an inlet hose, the water from the inlet hose first enters the inlet sleeve of the inlet tank after passing through the inlet pipe. Then, the water is pressurized by a booster pump on the inlet pipe, and the pressurized high-speed water flow enters the inlet tank. Multiple water wheel buckets are arranged around the connecting plate to receive the water flow sprayed from the inlet sleeve. Under the impact of the high-speed water flow, the water wheel buckets around the connecting plate rotate, thereby driving the central shaft to rotate through the connecting plate and the multiple water wheel buckets. At this time, the rotation of the central shaft drives the first bevel gear to rotate, and the first bevel gear drives the linkage shaft to rotate through the second bevel gear. Then, the linkage shaft drives the movable gear to rotate. Since the movable gear meshes with the fixed gear, the movable gear can rotate around the fixed gear. This drives the inlet tank to rotate around the rotating shaft, and the inlet tank drives the spray pipe to rotate around the rotating shaft. The water flow sprayed from the first nozzle on the spray pipe rotates around the rotating shaft, which ultimately helps to achieve stable rotating water spray irrigation.

[0024] When the central shaft rotates, it also drives the rotating arm to rotate. Since the drive column of the rotating arm is embedded in a long sleeve that extends vertically, as the drive column rotates around the central shaft, it drives the piston rod to extend and retract via the long sleeve. When the piston rod drives the piston block to move towards the second nozzle within the piston sleeve, water inside the piston sleeve is squeezed out from the second nozzle. Because the pressure exerted by the piston block on the water inside the piston sleeve is limited, the water jet from the second nozzle has a relatively short range. This allows for watering nearby plants. Conversely, because the water pressure inside the nozzle is relatively high, the water jet from the first nozzle has a longer range, allowing for watering distant plants. Simultaneously, when the piston rod drives the piston block to move away from the second nozzle within the piston sleeve and past the inlet hole, water from the water tank is injected into the piston sleeve through the inlet hole, facilitating the next spraying of the second nozzle.

[0025] Simultaneously, when the piston block moves towards the side closer to the second nozzle within the piston sleeve, it needs to squeeze the water inside the sleeve. At this time, the piston block experiences significant damping force. This obstruction in movement is relayed to the central shaft via the long sleeve and rotating arm, hindering its rotation. Consequently, the rotation of the water wheel around the connecting plate is also obstructed, preventing it from rotating smoothly with the water entering the inlet sleeve. This sluggish rotation of the water wheel interferes with the flow rate of the water in the inlet tank, ultimately shortening the range of the water jet ejected from the first nozzle. Simultaneously, when the piston block moves away from the second nozzle within the piston sleeve, due to… The sealing block fits against the inner wall of the piston sleeve and is used to block the water inlet hole. The reverse movement of the piston block no longer requires squeezing water and only needs to draw in outside air through the second nozzle. Therefore, the central shaft can rotate more smoothly. Then, the water wheel bucket can rotate smoothly with the water entering the water inlet sleeve. At this time, the water wheel bucket no longer interferes with the flow rate of the water in the water inlet tank, which will eventually make the water jet from the first nozzle have a longer range. At this time, the extension and retraction of the piston block can affect the range of the water jet from the first nozzle, causing the water jet range of the first nozzle to change from near to far. Ultimately, this will help the first nozzle to cover plants at various distances.

[0026] When the long sleeve moves left and right under the drive column, it can drive the nozzle to move left and right through the telescopic column and the fixed seat. The corrugated hose can deform arbitrarily to ensure a stable connection between the nozzle and the water spray pipe. This allows the water jet from the first nozzle to move left and right while rotating around the axis. Simultaneously, the end of the telescopic column is embedded in the bearing sleeve on the long sleeve, enabling rotational connection. The telescopic column has a spiral guide groove, and the guide sleeve has a guide column embedded in the guide groove. Therefore, the telescopic column can deflect back and forth while moving left and right. This deflection drives the nozzle to swing up and down, allowing the water jet from the first nozzle to swing up and down while rotating around the axis and moving left and right. This further increases the coverage area of ​​the first nozzle's irrigation, ultimately facilitating efficient plant irrigation. Attached Figure Description

A guide column 4611 embedded in the guide groove 7311 is integrally provided on the inner wall of the guide sleeve 461.

[0041] Principle: When irrigation is carried out using the inlet hose 1, the water from the inlet hose 1 first passes through the inlet pipe 212 and then enters the inlet sleeve 41 of the inlet tank 4. The water is then pressurized by the booster pump 213 on the inlet pipe 212, and the pressurized high-speed water flow enters the inlet tank 4. Multiple waterwheels 442 arranged around the connecting plate 441 receive the water jet from the inlet sleeve 41. Under the impact of the high-speed water flow, the waterwheels 442 around the connecting plate 441 rotate, thereby driving the central shaft 44 through the connecting plate 441 and the multiple waterwheels 442. Rotation; at this time, the rotation of the central shaft 44 drives the first bevel gear 51 to rotate, and the first bevel gear 51 can drive the linkage shaft 53 to rotate through the second bevel gear 54. Subsequently, the linkage shaft 53 can drive the movable gear 55 to rotate. Since the movable gear 55 meshes with the fixed gear 56, the movable gear 55 can rotate around the fixed gear 56. At this time, the water inlet tank 4 can rotate around the rotating shaft 22, and the water inlet tank 4 can drive the spray pipe 3 to rotate around the rotating shaft 22. The water flow sprayed from the first nozzle on the spray pipe 3 can rotate around the rotating shaft 22, which is conducive to the stable realization of rotating water spray irrigation.

[0042] When the central shaft 44 rotates, it can also drive the rotating arm 71 to rotate. Since the drive column 72 of the rotating arm 71 is embedded in the elongated sleeve 73, and the elongated sleeve 73 extends vertically, as the drive column 72 rotates around the central shaft 44, it can drive the piston rod 62 to extend and retract via the elongated sleeve 73. When the piston rod 62 drives the piston block 61 to move towards the side closer to the second nozzle 64 within the piston sleeve 6, the water inside the piston sleeve 6 can be squeezed out from the side of the second nozzle 64. Because the pressure exerted by the piston block 61 on the water inside the piston sleeve 6 is limited, the water inside the second nozzle 64... The water jet has a relatively short range, so the water can be sprayed onto nearby plants through the second nozzle 64. However, due to the high pressure of the water in the nozzle 3, the water jet from the first nozzle 31 has a longer range, so the water can be sprayed onto distant plants through the first nozzle 31 and onto nearby plants through the second nozzle 64. At the same time, when the piston rod 62 moves the piston block 61 away from the second nozzle 64 within the piston sleeve 6 and passes the water inlet 451, the water in the water tank 4 can be injected into the piston sleeve 6 through the water inlet 451, thus facilitating the next spraying of water from the second nozzle 64.

[0043] Simultaneously, when piston block 61 moves towards the side closer to the second nozzle 64 within piston sleeve 6, piston block 61 needs to squeeze the water within piston sleeve 6. At this time, piston block 61 will experience a large damping force. After the movement of piston block 61 is obstructed, it can be fed back to the central shaft 44 through the long sleeve 73 and rotating arm 71, thus obstructing the rotation of the central shaft 44. Subsequently, the rotation of the water wheel 442 around the connecting plate 441 will be obstructed, preventing the water wheel 442 from rotating smoothly with the water entering the inlet sleeve 41. At this time, the water wheel 442, which cannot rotate smoothly, will interfere with the flow rate of the water in the inlet tank 4, ultimately reducing the range of the water jet from the first nozzle 31. At the same time, when piston block 61 moves away from the second nozzle 64 within piston sleeve 6... When in motion, since the sealing block 621 is attached to the inner wall of the piston sleeve 6 and is used to block the water inlet hole 451, the reverse movement of the piston block 61 no longer requires squeezing water and only needs to draw in outside air through the second nozzle 64. Therefore, the central shaft 44 can rotate relatively smoothly. Subsequently, the water wheel bucket 442 can rotate smoothly with the water entering the water inlet sleeve 41. At this time, the water wheel bucket 442 no longer interferes with the flow rate of the water in the water inlet tank 4, which will eventually make the water jet from the first nozzle 31 have a longer range. At this time, the extension and retraction of the piston block 61 can affect the range of the water jet from the first nozzle 31, causing the water jet range of the first nozzle 31 to change from near to far. Ultimately, this will help the first nozzle 31 to cover plants at various near and far positions.

[0044] When the elongated sleeve 73 moves left and right under the drive of the drive column 72, the elongated sleeve 73 can drive the nozzle 3 to move left and right through the telescopic column 731 and the fixed seat 732. The corrugated hose 8, after any deformation, ensures a stable connection between the nozzle 3 and the water spray pipe 43. This allows the water jet from the first nozzle 31 to move left and right while rotating around the rotating shaft 22. Simultaneously, by embedding the end of the telescopic column 731 into the bearing sleeve 73 on the elongated sleeve 73, a rotatable connection of the telescopic column 731 on the elongated sleeve 73 can be achieved. The telescopic column 731 has a spiral guide groove 7311, and the inner wall of the guide sleeve 461 is provided with a guide post 4611 embedded in the guide groove 7311. Therefore, the telescopic column 731 can move left and right and deflect back and forth at the same time. The back and forth deflection of the telescopic column 731 can drive the nozzle 3 to swing up and down. At this time, the water jet from the first nozzle 31 can swing up and down while rotating around the rotating shaft 22 and moving left and right, thereby further increasing the coverage area of ​​the irrigation of the first nozzle 31, which is conducive to the efficient irrigation of plants.
