Description

Technical Field

[0001] The invention relates to the technical field of irrigation sprinklers, in particular to a hidden gardening irrigation device with a wide irrigation range. Background Art

[0002] Gardens are not only for recreation, but also have the function of protecting and improving the environment. Cities create beautiful gardens by transforming the terrain, planting trees, flowers and plants, building buildings and arranging garden paths. The plants in the gardens are very important, and most of these plants are cultivated artificially and cannot be separated from people's care. Garden irrigation is a technical measure to supplement the soil moisture required for the growth of garden plants to improve their growth conditions. Use artificial or mechanical methods to supplement the soil moisture of the garden green space in different irrigation forms to meet the water needs of plants.

[0003] When sprinkling water on garden landscaping, an irrigation nozzle is usually installed on a water pipe, and pressurized water is passed through the water pipe so that water is sprayed out from the nozzle of the irrigation nozzle. When the water jet passes through the rocker arm of the irrigation nozzle, the reaction force of the rocker arm causes the irrigation nozzle to rotate, so that the irrigation nozzle sprays water evenly. However, when the water pressure of the water sprayed by the irrigation nozzle is constant, the spraying range of the irrigation nozzle is constant under the action of the same water pressure. When the spraying direction of the irrigation nozzle is constant, the spraying range cannot be increased again. In order to increase the spraying direction of the irrigation nozzle when the water pressure is constant, we propose a hidden garden landscaping irrigation device with a wide irrigation range.

A first fan blade 27 is fixedly mounted on the outer surface of the rotating pipe 3.

[0031] After entering through the water inlet pipe 1, the water enters the first fan blade 27 through the first water hole 28, and then the water is discharged from the second water hole 14. During this process, it will drive the first fan blade 27 and the rotating tube 3 to rotate, thereby realizing the revolution of the rotating tube 3. Then, the water enters the interior of the rotating tube 3 through a number of connecting holes 15.

[0032] A third annular block 25 is fixedly connected to the inner wall of the rotating tube 3, the bottom of the rotating rod 30 is rotatably connected to the third annular block 25, the outer surface of the rotating rod 30 is rotatably sleeved with a fourth annular block 17, the fourth annular block 17 is fixedly connected to the inner wall of the rotating tube 3, a third water hole 16 is opened on the third annular block 25, a fourth water hole 23 is opened on the fourth annular block 17, and a second fan blade 24 is fixedly sleeved on the outer surface of the rotating rod 30.

[0033] The water entering the rotating tube 3 will enter the position of the second fan blade 24 through the third water hole 16, and finally the water will flow out through the fourth water hole 23, thereby causing the rotating rod 30 to rotate.

[0034] The flow-limiting water spray assembly includes two groups of inner conical hollow sleeves 21, the inner conical hollow sleeves 21 are fixedly connected to the inner wall of the water spray pipe 4, the inner shell 36 is fixedly connected to the interior of the top shell 5, a slide rod 40 is arranged inside the water spray pipe 4, one end of the slide rod 40 is fixedly connected to the conical block 20, the other end of the slide rod 40 is slidably penetrated into the interior of the inner shell 36, and the other end of the slide rod 40 is fixedly connected to a plurality of annular convex teeth 38, and a transmission mechanism is installed on the left and right sides of the interior of the inner shell 36, the transmission mechanism includes an upper transmission gear 41 at the top and a lower transmission gear 39 at the bottom, the upper transmission gear 41 is meshed with the annular convex teeth 38, the back of the top shell 5 is fixedly connected to the back shell 22, and the back shell 2 2 is provided with a rotating mechanism for driving the upper transmission gear 41 to rotate; the rotating mechanism includes a cylinder shell 9, which is fixedly connected to the back of the back shell 22, wherein the rotating shaft of one group of the upper transmission gears 41 extends into the cylinder shell 9, and the outer surface of the rotating shaft extending into the cylinder shell 9 is fixedly installed with a third fan blade 37, an upper gear 42 is fixedly installed on the rotating shaft of the upper transmission gear 41, a lower gear 43 is fixedly installed on the rotating shaft of the lower transmission gear 39, the upper gear 42 is meshed with the lower gear 43, and the upper gears 42 on the left and right sides are meshed with each other, the cylinder shell 9 is fixedly connected with the inside of the rotating pipe 3 through the soft connecting pipe 29, and the soft water pipe 6 is fixedly connected with the water outlet port of the cylinder shell 9.

[0035] The water flowing out of the fourth water hole 23 enters the cylinder shell 9 through the soft connecting pipe 29, then enters the rotary joint 33 through the soft water pipe 6, then enters the top shell 5 through the hollow column 32, and finally sprays out through the water spray pipe 4. When the water passes through the cylinder shell 9, it will drive one group of upper transmission gears 41 to rotate. Since the upper gear 42 is meshed with the lower gear 43, the upper gears 42 on the left and right sides are meshed with each other, and then the upper transmission gear 41 and the lower transmission gear 39 will rotate in the opposite direction, and the upper transmission gear 41 When the upper transmission gear 41 rotates in the opposite direction to the lower transmission gear 39, the upper transmission gear 41 first contacts the annular convex tooth 38. When the upper transmission gear 41 rotates and no longer contacts the annular convex tooth 38, the lower transmission gear 39 will just contact the annular convex tooth 38. At this time, the slide bar 40 can reciprocate left and right, causing the conical block 20 to move away from or close to the inner conical hollow sleeve 21. When the conical block 20 approaches, the water outlet volume is reduced, which can change the water pressure inside the water spray pipe 4, thereby changing the water pressure inside the water spray pipe 4 and increasing the irrigation range.

[0036] The reset assembly includes a piston 10, which is fixedly mounted on the outer surface of the lifting pipe 2. The piston 10 is slidably connected to the inner wall of the water inlet pipe 1.

Under the action of the lightweight spring 12, when the water source is closed, the lifting pipe 2 will move downward to reset, thereby playing a hiding role.

[0037] A filter screen is fixedly installed at the inner bottom of the water inlet pipe 1 to filter the incoming water to avoid blockage inside the device.

[0038] The transmission gear 35 , the driving gear 45 and the driven gear 34 are covered with a protective cover 31 . The protective cover 31 is fixedly connected to the connecting plate 7 . The protective cover 31 can protect the transmission gear 35 , the driving gear 45 and the driven gear 34 from dust.

[0039] Working principle: When in use, external water passes through the water inlet pipe 1, and then the water enters and enters the first fan blade 27 through the first water hole 28, and then the water is discharged from the second water hole 14. In the process, it will drive the first fan blade 27 and the rotating tube 3 to rotate, so as to realize the revolution of the rotating tube 3, and then the water enters the interior of the rotating tube 3 through a plurality of connecting holes 15. The water entering the interior of the rotating tube 3 will enter the position of the second fan blade 24 through the third water hole 16, and then the water flows out through the fourth water hole 23, so as to make the rotating rod 30 rotate, and the water flowing out from the fourth water hole 23 enters the cylindrical shell 9 through the soft connecting pipe 29, and then the water enters the rotating joint 33 through the soft water pipe 6, and then the water enters the top shell 5 through the hollow column 32, and finally the water is sprayed out through the water spray pipe 4.

[0040] At this time, under the action of water pressure, the lifting pipe 2 and the rotating pipe 3 will be lifted, and the water spray pipe 4 will be exposed above the garden plants. The water spray pipe 4 will no longer be hidden. The water passes through the self-rotating component, and the water will drive the rotating pipe 3 and the water spray pipe 4 to rotate. When the water spray pipe 4 revolves, the garden trees can be irrigated evenly.

[0041] When the rotating rod 30 rotates, the rotating rod 30 will drive the active umbrella block 18 to rotate. A portion of the outer surface of the active umbrella block 18 is fixedly connected with a plurality of tooth blocks 46. When the active umbrella block 18 rotates, the tooth block 46 first contacts with one group of driven umbrella gears 8. When the tooth block 46 is separated from the current driven umbrella gear 8, the tooth block 46 will contact with another group of driven umbrella gears 8. Then, when the active umbrella block 18 rotates, the transmission rod 44 can be reciprocated. When the transmission rod 44 reciprocates, the upper transmission gear 35 is meshed with the driven gear 34, and the lower transmission gear 35 is meshed with the active gear 45, so that the top shell 5 and the water spray pipe 4 are reciprocated up and down, the water spraying angle of the water spray pipe 4 is changed, and the parabola of the water flow is changed, so that the irrigation range can be increased.

[0042] When the water passes through the cylinder shell 9, it will drive one group of upper transmission gears 41 to rotate. Since the upper gear 42 is meshed with the lower gear 43, the upper gears 42 on the left and right sides are meshed with each other, and then the upper transmission gear 41 and the lower transmission gear 39 will rotate in the opposite direction. When the upper transmission gear 41 and the lower transmission gear 39 rotate in the opposite direction, the upper transmission gear 41 first contacts with the annular convex teeth 38. When the upper transmission gear 41 is no longer in contact with the annular convex teeth 38 after rotation, the lower transmission gear 39 will just contact with the annular convex teeth 38. The teeth 38 are in contact, and the slide bar 40 is moved back and forth left and right at this time, so that the conical block 20 will move away from or close to the inner conical hollow sleeve 21. When the conical block 20 is close, the water outlet volume is reduced, and the water pressure inside the water spray pipe 4 can be changed, and then the water pressure inside the water spray pipe 4 can be changed. When changing the water spray volume, the water pressure can be increased, and then the irrigation range can be increased again. The flow-limiting water spray component can intermittently close the gap between the two groups of water spray pipes 4, and the water flow can be near and far, which can improve the uniformity of irrigation.
