Description

Technical Field

[0001] This utility model relates to the field of irrigation device technology, and in particular to a high-efficiency water-saving irrigation device. Background Technology

[0002] Targeted irrigation of fruit tree roots is often achieved through subsurface drip irrigation. Drip irrigation uses an average of 12% of the water required for traditional irrigation and 50% for sprinkler irrigation. The principle of drip irrigation is to supply water through drip tape (or drip pipe) placed at the base of the crop.

[0003] Patent document CN211210884U discloses a buried porous pipe irrigation device for fruit trees. Its features include an irrigation pipe comprising at least one main pipe, one branch pipe, and a connecting pipe. The main pipe is closed at at least one end, the branch pipe is closed at both ends, and the connecting pipe is open at both ends. The connecting pipe connects the main pipe and the branch pipe in series. Both the main pipe and the branch pipe have micropores on their walls, and the main pipe has a water inlet. Compared with existing technologies, this invention achieves root irrigation for deep-rooted trees while saving water. The device has a simple structure, low water evaporation, and high efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In actual use, the above-mentioned solutions lack anti-clogging mechanisms at the water outlets used for irrigation, which allows mud, sand, and gravel in the soil to easily enter the water outlets after the water pipes are buried in the soil, causing blockages and affecting subsequent irrigation effects. At the same time, the pipeline structure of the above-mentioned solutions lacks a spacing adjustment mechanism, which means that it cannot adjust the installation range according to the diameter of different fruit trees, thus having certain limitations. Utility Model Content

[0005] This utility model discloses a high-efficiency water-saving irrigation device, which aims to solve the technical problem caused by mud, sand and gravel in the soil easily entering the water outlet pipe through the water outlet hole after the irrigation device is buried in the soil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency water-saving irrigation device includes four connecting cylinders arranged in a rectangular array, with a connecting mechanism between the four connecting cylinders. A first connecting seat is embedded on the surface of the connecting cylinder, and a water supply pipe is threadedly connected to the inside of the first connecting seat. The end of the water supply pipe on the left side away from the first connecting seat is connected to an external water supply device. A second connecting seat is embedded at the lower end of the connecting cylinder, and a buried pipe is threadedly connected to the surface of the second connecting seat. A water outlet hole is opened on the surface of the buried pipe, and a filter element is installed inside the buried pipe.

[0008] In a preferred embodiment, the surface of the first connector is provided with external threads, and a sealing cap is connected to the surface of the first connector via the external threads.

[0009] The sealing cap allows for the sealing of the connecting cylinder that does not require connection to a water pipe, facilitating the operation of the irrigation device with an external water source.

[0010] In a preferred embodiment, a sealing ring is embedded in the inner wall of the first connecting seat.

[0011] By using a sealing ring, the sealing performance of the water pipe after it is connected to the first connector can be improved.

[0012] In a preferred embodiment, the number of water outlet holes is several, and the several water outlet holes are divided into several groups of eight, with the several groups of water outlet holes being equally spaced on the surface of the buried pipe.

[0013] In a preferred embodiment, the connecting mechanism includes an outer sleeve and an inner sleeve, which are respectively fixedly installed on opposite sides of the two connecting cylinders. The inner sleeve is slidably connected to the interior of the outer sleeve. A sliding opening is provided on the surface of the outer sleeve. A screw is fixedly connected to the surface of the inner sleeve and is slidably connected to the interior of the sliding opening. A fixing nut is threaded to one end of the screw that extends out of the surface of the outer sleeve. The two connecting cylinders are interconnected by a telescopic hose.

[0014] The flexible hose allows water to be exchanged between the four connecting tubes while their spacing can be adjusted. The outer and inner sleeves limit and fix the spacing between the connecting tubes, while also protecting the flexible hose.

[0015] In a preferred embodiment, the upper end of the connecting cylinder is fitted with an expansion cover, and a filter screen is fixedly connected to the inner wall of the expansion cover.

[0016] The expansion cover makes the upper end of the connecting cylinder open, which can collect rainwater and filter out debris such as leaves through the filter screen.

[0017] In a preferred embodiment, a conical baffle is fixedly connected to the inner wall of the outer expansion cover, and a drainage micro-hole is provided at the tip of the conical baffle.

[0018] The conical baffle design ensures that water will not leak out through the outer expansion cover when the water pipe delivers water to the connecting cylinder.

[0019] As can be seen from the above, the high-efficiency water-saving irrigation device provided by this utility model has the following technical effects.

[0020] Firstly, the external water supply equipment delivers water to the connecting cylinder through the water pipe. The water in the connecting cylinder enters the buried pipe and is discharged through the outlet hole to irrigate the roots of the trees. During this process, the filter core can block the mud, sand and gravel in the soil, preventing them from entering the buried pipe through the outlet hole, thus achieving the purpose of preventing blockage.

[0021] Secondly, when it is necessary to adjust the size of the irrigation device, the fixing nut on the surface of the screw can be loosened. Without the restriction of the fixing nut, the outer sleeve can be pulled to slide on the surface of the inner sleeve, thereby achieving the effect of adjusting the spacing and improving the practicality of the device.

[0022] Thirdly, during rainy days, the outer cover can collect rainwater, allowing it to directly nourish tree roots through the ground via the irrigation device. The filter screen can also filter out external debris such as leaves, preventing them from entering the connecting cylinder and causing blockages. Attached Figure Description

[0031] Reference Figures 1-5 A high-efficiency water-saving irrigation device includes four connecting cylinders 1 arranged in a rectangular array, with a connecting mechanism between the four connecting cylinders 1. A first connecting seat 2 is embedded on the surface of the connecting cylinder 1, and a water supply pipe 3 is threadedly connected to the inside of the first connecting seat 2. The end of the left water supply pipe 3 away from the first connecting seat 2 is connected to an external water supply device. A second connecting seat 4 is embedded at the lower end of the connecting cylinder 1, and a buried pipe 5 is threadedly connected to the surface of the second connecting seat 4. A water outlet hole 6 is opened on the surface of the buried pipe 5. The number of water outlet holes 6 is several, and the several groups of water outlet holes 6 are divided into several groups of eight. The several groups of water outlet holes 6 are equidistantly opened on the surface of the buried pipe 5. A filter element 7 is installed inside the buried pipe 5.

[0032] Reference Figure 1 and Figure 4 In a preferred embodiment, the surface of the first connecting seat 2 is provided with an external thread, and the surface of the first connecting seat 2 is connected to a sealing cover 8 through the external thread. By providing the sealing cover 8, the connecting cylinder 1 that does not need to be connected to the water supply pipe 3 can be sealed, which facilitates the operation of the irrigation device with an external water source.

[0033] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, a sealing ring 9 is embedded in the inner wall of the first connecting seat 2. The sealing performance of the water pipe 3 after it is connected to the first connecting seat 2 can be improved by setting the sealing ring 9.

[0034] Reference Figure 4 and Figure 5 In a preferred embodiment, the connecting mechanism includes an outer sleeve 10 and an inner sleeve 11, which are respectively fixedly installed on opposite sides of the two connecting cylinders 1. The inner sleeve 11 is slidably connected to the inside of the outer sleeve 10. The surface of the outer sleeve 10 is provided with a sliding opening. The surface of the inner sleeve 11 is fixedly connected with a screw 12 that is slidably connected to the inside of the sliding opening. One end of the screw 12 extending out of the surface of the outer sleeve 10 is threadedly connected with a fixing nut 13. The two connecting cylinders 1 are interconnected through a telescopic hose 14.

[0035] The flexible hose 14 allows water to be supplied between the four connecting tubes 1 while their spacing can be adjusted. Under the action of the outer sleeve 10 and the inner sleeve 11, the spacing between the connecting tubes 1 can be limited and fixed, while also providing protection for the flexible hose 14.

[0036] Reference Figure 2 and Figure 3 In a preferred embodiment, an outer expansion cover 15 is embedded at the upper end of the connecting cylinder 1, and a filter screen cover 16 is fixedly connected to the inner wall of the outer expansion cover 15. By setting the outer expansion cover 15, the upper end of the connecting cylinder 1 is open, which can collect rainwater and filter out external debris such as leaves under the action of the filter screen cover 16.

[0037] Reference Figure 2 and Figure 3 In a preferred embodiment, a conical baffle 17 is fixedly connected to the inner wall of the outer expansion cover 15. The conical baffle 17 has a drainage microhole at its pointed tip. The conical baffle 17 ensures that water will not flow out through the outer expansion cover 15 when the water supply pipe 3 delivers water to the connecting cylinder 1.

[0038] Working principle: When in use, the irrigation device is fitted onto the outside of the tree, and the buried pipe 5 is buried in the soil. When it is necessary to adjust the size of the irrigation device, the fixing nut 13 on the surface of the screw 12 is loosened. Without the restriction of the fixing nut 13, the outer sleeve 10 can be pulled to slide on the surface of the inner sleeve 11, thereby adjusting the spacing. Subsequently, the external water supply equipment delivers water to the connecting cylinder 1 through the water pipe 3. The water in the connecting cylinder 1 enters the buried pipe 5 and is discharged through the water outlet 6 to irrigate the roots of the tree. During this process, the filter core 7 can block the mud, sand and gravel in the soil, preventing them from entering the buried pipe 5 through the water outlet 6. In rainy weather, the outer expansion cover 15 can collect rainwater, allowing the rainwater to directly moisten the tree roots through the ground surface via the irrigation device. The filter screen 16 can filter out external debris such as leaves, preventing them from entering the connecting cylinder 1 and causing blockage.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
