Description

Technical Field

[0001] The utility model relates to the field of gardening and greening, in particular to a watering device for gardening and greening. Background Art

[0002] Landscaping is the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, transforming the terrain (or further building mountains, stacking stones, and managing water), planting trees, flowers, and plants, constructing buildings, and arranging garden paths. It is called a garden. A garden includes courtyards, residential gardens, small gardens, flower gardens, parks, botanical gardens, zoos, etc. With the development of the discipline of gardening, it also includes forest parks, scenic spots, nature reserves or tourist areas of national parks, as well as resorts.

[0003] In landscaping, there are some plants that require special care through fine irrigation, such as flowers and hedges. The use of irrigation devices can achieve local micro-irrigation to meet the growth needs of plants and promote the healthy growth of plants and the sustainable development of landscaping. However, due to different plant species, their coverage areas are also different, and the irrigation range must be controlled during watering. In order to ensure the realization of water-saving, energy-saving, high-efficiency and environmentally friendly irrigation goals, corresponding water pipelines are generally set up near the top of the vegetation, and corresponding watering nozzles are set above the corresponding plants, and drip irrigation and water-saving irrigation modes are achieved through the nozzles.

[0004] With respect to the above-mentioned related technologies, the inventors found that due to the differences in plant species and growth cycles, the range of green vegetation produced is also different. During the irrigation process, water droplets will be irrigated in a parabolic manner. Due to the different growth heights and green leaf coverage rates of some plants, the water droplets cannot accurately cover the green leaf surface or the rhizomes of plants during watering, and the slopes of the planting terrain are different, so some areas cannot be irrigated, resulting in a waste of water resources. In addition, some plants require different amounts of water. When the plants are saturated with water, the corresponding irrigation nozzles cannot be closed, which can easily lead to excessive water in the roots of the plants and rot. In addition, the water flow switch is only used to control the flow of water in the water pipe, which has certain limitations. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a watering device for gardening, which is convenient for accurately covering the surface of green leaves or the roots of plants during watering, while expanding the watering range to prevent some areas from being unable to be irrigated, saving water resources, and also convenient for controlling the corresponding watering nozzles to be closed or opened.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a gardening irrigation device, including: a transmission water pipe assembly, a plurality of telescopic drip irrigation assemblies are installed at intervals on the surface of the transmission water pipe assembly, the telescopic drip irrigation assembly includes a shunt pipe joint, a telescopic pipe, a limit connector and a diffusion nozzle installed in sequence from top to bottom, a threaded sleeve is installed at the bottom of the shunt pipe joint, the threaded sleeve is sleeved on the outside of the telescopic pipe, the upper rotation of the limit connector is connected with a connecting sleeve, and the connecting sleeve is threadedly connected with the threaded sleeve;

[0007] The diffusion type nozzle component comprises a shell with a rounded bottom edge, a plurality of water outlet holes are provided on the rounded corner of the shell, a water blocking mechanism is installed in the shell, and also comprises a driving rod mechanism for driving the water blocking mechanism to rotate.

[0008] By adopting the above technical solution, the threaded rotation of the connecting sleeve and the threaded sleeve controls the distance between the opposite ends of the two, thereby controlling the height of the diffusion nozzle component, thereby controlling the irrigation range of the diffusion nozzle component. The closer the diffusion nozzle component is to the plant, the more water droplets are irrigated towards the diameter of the plant, thereby achieving effective irrigation and saving water resources. After a certain amount of water is irrigated, the driving rod mechanism that drives the water blocking mechanism to rotate is used to block the water outlet hole, thereby facilitating the control of the corresponding irrigation nozzle to be closed.

[0009] In a preferred example, the utility model can be further configured as follows: the water blocking mechanism includes a plurality of arc-shaped pressure plates matching the bottom of the shell cavity, the outer sides of the arc-shaped pressure plates are respectively connected to sealing gaskets, and the sealing gaskets are respectively connected to elastic waterproof protrusions matching water outlet holes.

[0010] By adopting the above technical solution, the driving rod mechanism drives the arc pressure plate to rotate, so that the elastic waterproof protrusion blocks the water outlet hole, and with the cooperation of the sealing gasket, prevents water droplets from flowing out of the shell, thereby controlling the corresponding irrigation nozzle to be closed, saving water, and preventing the corresponding plant roots from rotting due to excessive water.

[0011] In a preferred example, the utility model can be further configured as follows: the driving rod mechanism includes a rod body passing through the bottom of the shell, a waterproof ring is sleeved on the outer side of the rod body, the waterproof ring is connected to the shell, a plurality of connecting arms are connected to the top of the rod body, one end of each connecting arm is respectively connected to one end of an arc-shaped pressure plate, the other end of the arc-shaped pressure plate is connected to the rod body, a driving paddle is connected to the bottom of the rod body, a clamping spring is provided above the driving paddle, and the clamping spring is sleeved on the outer side of the rod body and is located between the shell and the driving paddle.

[0012] By adopting the above technical solution, the driving paddle drives the rod body to rotate, so that the rod body drives the arc pressure plate to rotate, and because the compression spring squeezes the driving paddle against each other, the sealing gasket can be tightly fitted to the bottom of the inner cavity of the shell, and the elastic waterproof protrusion can tightly block the water outlet hole, thereby achieving water sealing.

[0013] In a preferred example, the utility model can be further configured as follows: a plurality of water outlet holes 2 are symmetrically arranged at the bottom of the shell, and the water outlet holes 2 are symmetrically arranged in pairs around the bottom center of the shell; the bottom of the arc-shaped pressure plate is respectively connected with two elastic waterproof protrusions matching the water outlet holes 2; when the elastic waterproof protrusions 1 are respectively located in the water outlet holes 1, the elastic waterproof protrusions 2 are respectively located in the water outlet holes 2.

[0014] By adopting the above technical solution, the second water outlet hole expands the irrigation range of the diffusion nozzle, so that water droplets drip vertically along the bottom and flow directly to the plant diameter to achieve effective irrigation. At the same time, under the action of the second elastic waterproof protrusion, the second water outlet hole is blocked to prevent water from flowing out.

[0015] In a preferred example, the present invention can be further configured as follows: the telescopic tube is an accordion-type telescopic tube.

[0016] By adopting the above technical solution, the accordion-type telescopic tube ensures that the length of the telescopic tube can be adjusted, so that the diffusion-type sprinkler head can be close to or away from the green plants, thereby controlling the range of the controller watering and fully improving the irrigation area.

[0017] In a preferred example, the utility model can be further configured as follows: the transmission water pipe assembly includes a pipe body, and two sides of the pipe body are respectively connected to connecting flanges.

[0018] By adopting the above technical solution, the connecting flange is connected to the external water supply pump and other related water supply parts.

[0019] In summary, the utility model includes at least one of the following beneficial technical effects of the gardening irrigation device:

[0020] 1. The threaded rotation of the connecting sleeve and the threaded sleeve controls the distance between the opposite ends of the two, thereby controlling the height of the diffusion nozzle, thereby controlling the irrigation range of the diffusion nozzle. The closer the diffusion nozzle is to the plant, the more water droplets will irrigate the plant diameter. The farther away from the plant, the wider the irrigation range, thereby increasing the irrigation area and achieving effective irrigation.

[0021] 2. After a certain amount of water is irrigated, the rod body is driven to rotate by the driving paddle, so that the rod body drives the arc-shaped pressure plate to rotate, and because the compression spring squeezes the driving paddle against each other, the sealing gasket can be tightly fitted to the bottom of the inner cavity of the shell, and the elastic waterproof protrusion 1 tightly blocks the water outlet hole 1, and the elastic waterproof protrusion 2 blocks the water outlet hole 2, thereby achieving water sealing, which makes it easy to control the corresponding irrigation nozzle to be closed or opened.

[0037] Reference Figure 1-6 , is a gardening irrigation device disclosed in the utility model, comprising: a transmission water pipe assembly 10, the transmission water pipe assembly 10 comprises a pipe body 11, and connecting flanges 12 are respectively connected to both sides of the pipe body 11, and a plurality of telescopic drip irrigation assemblies 20 are installed at intervals on the surface of the transmission water pipe assembly 10, and the telescopic drip irrigation assembly 20 comprises a shunt pipe joint 21, a telescopic pipe 22, a limit connector 23 and a diffusion nozzle 24 which are installed in sequence from top to bottom, a threaded sleeve 25 is installed at the bottom of the shunt pipe joint 21, and the threaded sleeve 25 is sleeved on the outside of the telescopic pipe 22, and a connecting sleeve 26 is rotatably connected to the upper part of the limit connector 23, and the connecting sleeve 26 is threadedly connected to the threaded sleeve 25, and the telescopic pipe 22 is an accordion-type telescopic pipe, and the diffusion nozzle 24 comprises a shell 241 with a rounded bottom edge, A plurality of water outlet holes 242 are provided on the rounded corners of the shell 241, a water blocking mechanism 243 is installed in the shell 241, and also includes a driving rod mechanism 244 for driving the water blocking mechanism 243 to rotate; the connecting flange 12 is connected to the corresponding water supply pump and other related water supply parts by bolts. After the water is supplied, the staff rotates the connecting sleeve 26 to stretch the telescopic tube 22 within a suitable range according to the plant type, green leaf coverage rate and moisture content required for the corresponding growth cycle under the diffusion nozzle component 24, and controls the height of the diffusion nozzle component 24 from the plant. The closer the diffusion nozzle component 24 is to the plant, the more water droplets tend to irrigate the plant diameter. When the diffusion nozzle component 24 is far away from the plant, the wider the irrigation parabola range of the water droplets is, which can effectively cover the growth range of the plant and achieve effective irrigation.

[0038] The water blocking mechanism 243 includes a plurality of arc-shaped pressing plates 2431 matching the bottom of the inner cavity of the shell 241, and the outer sides of the arc-shaped pressing plates 2431 are respectively connected with sealing pads 2432, and the sealing pads 2432 are respectively connected with elastic waterproof protrusions 2433 matching the water outlet holes 242, and the bottom of the shell 241 is symmetrically provided with a plurality of water outlet holes 245, and the water outlet holes 245 are respectively arranged symmetrically around the bottom circle center of the shell 241, and the bottom of the arc-shaped pressing plates 2431 is respectively connected with elastic waterproof protrusions 2434 matching the water outlet holes 245, and when the elastic waterproof protrusions 2433 are respectively located in the water outlet holes 242, the elastic waterproof protrusions 2434 are respectively connected. 34 are respectively located in the second water outlet hole 245; the elastic waterproof protrusion 1 2433 and the elastic waterproof protrusion 2434 are both made of rubber material, the water outlet hole 1 242 is preferably 6 distributed in a circular array, and the water outlet hole 245 is preferably 2 symmetrically arranged. When the moisture content of the plant below the corresponding diffusion nozzle part 24 reaches the standard, the arc pressure plate 2431 is driven to rotate through the driving rod mechanism 244, so that the corresponding elastic waterproof protrusion 1 2433 enters the corresponding water outlet hole 1 242, and the corresponding elastic waterproof protrusion 2 2434 enters the corresponding water outlet hole 245, and under the action of the sealing gasket 2432, water overflow is prevented, and the roots of the plants are prevented from rotting due to excessive moisture.

[0039] The driving rod mechanism 244 includes a rod body 2441 that is inserted into the bottom of the shell 241, a waterproof ring 2442 is sleeved on the outer side of the rod body 2441, and the waterproof ring 2442 is connected to the shell 241. A plurality of connecting arms 2443 are connected to the top of the rod body 2441, and one end of the connecting arm 2443 is respectively connected to one end of the arc-shaped pressure plate 2431, and the other end of the arc-shaped pressure plate 2431 is connected to the rod body 2441. A driving paddle 2444 is connected to the bottom of the rod body 2441, and a clamping spring 2445 is provided above the driving paddle 2444. The clamping spring 2445 is sleeved on the outer side of the rod body 2441 and is located between the shell 241 and the driving paddle 2444; a water outlet hole When the second 245 and the elastic waterproof protrusion second 2434 are separated for irrigation, the driving paddle 2444 and the water outlet hole 245 are staggered with each other, so as to ensure that the water flows straight downward and flows along the diameter of the plant for irrigation. If the corresponding diffusion nozzle component 24 is controlled to be closed, the driving paddle 2444 drives the rod body 2441 to rotate, so that the rod body 2441 drives the arc pressure plate 2431 to rotate, and because the compression spring 2445 squeezes the driving paddle 2444 against each other, the sealing gasket 2432 can be tightly fitted to the bottom of the inner cavity of the shell 241, and the elastic waterproof protrusion 1 2433 can tightly block the water outlet hole 1 242, and the elastic waterproof protrusion 2 2434 can tightly block the water outlet hole 245.

[0040] The implementation principle of this embodiment is as follows: when in use, the staff rotates the connecting sleeve 26 according to the type of corresponding plants, the green leaf coverage rate and the moisture content required in the corresponding growth period, controls the distance between the threaded sleeve 25 and the opposite ends of the connecting sleeve 26, and stretches the telescopic tube 22 within a suitable range. When the diffusion nozzle 24 is closer to the plant, the water droplets tend to irrigate the plant diameter. When the diffusion nozzle 24 is far away from the plant, the water droplet irrigation parabola range is wider, which can effectively cover the growth range of the plant and achieve effective irrigation. When the plants have enough water, the staff rotates the driving paddle 2444 to drive the rod body 2441 to rotate, and the rod body 2441 drives the arc pressure plate 2431 to rotate. At this time, the elastic waterproof protrusion 1 2433 blocks the water outlet hole 1 242, and the elastic waterproof protrusion 2 2434 blocks the water outlet hole 245. Because the compression spring 2445 squeezes the driving paddle 2444 against each other, the sealing gasket 2432 can be closely fitted to the bottom of the inner cavity of the shell 241, thereby improving the sealing effect of the shell 241 and preventing water droplets from overflowing.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
