Description

Technical Field

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

[0002] During the seedling stage of fruit trees, the root system is relatively small, making it crucial to precisely deliver water to the vicinity of the seedling roots. This significantly reduces unnecessary water waste. Drip irrigation can precisely supply water to fruit plants to meet the specific water requirements of fruit seedlings during their growth stage. However, while existing drip irrigation equipment places drip heads around the seedling roots, these heads are located on the soil surface. Water discharged from the drip head must penetrate downwards from the soil surface before being absorbed by the seedling roots. Water on the soil surface cannot be directly absorbed by the roots and is eventually lost through evaporation, undoubtedly resulting in significant water waste. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides a water-saving drip irrigation device for fruit seedlings. Water is dripped directly from the insertion tube into the soil at the root of the fruit tree seedling, which facilitates the direct absorption of water by the seedling. The outlet of the drip irrigation head is located inside the soil, which can reduce the evaporation of water from the soil surface and achieve the technical effect of water saving.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] A water-saving drip irrigation device for fruit seedlings includes a main pipe, branch pipes, and drip heads. The main pipe has several branch pipes, and each branch pipe has a drip head. Each drip head includes a valve, an insertion tube, a conical head, and a sliding rod. The upper end of the conical head has the sliding rod, the diameter of which is smaller than the inner diameter of the insertion tube. The sliding rod is slidably connected to the insertion tube, and a water flow channel is provided between the sliding rod and the insertion tube. The insertion tube has the valve, and the valve is connected to the branch pipes.

[0006] Furthermore, the drip irrigation head also includes a column, a horizontal rod, and a C-shaped guide rod. The column is connected to the horizontal rod, and the horizontal rod is provided with the C-shaped guide rod. The notch of the C-shaped guide rod faces downward, and the C-shaped guide rod is slidably connected to the insertion tube. When the lower end of the insertion tube is located directly below the column, the upper end of the insertion tube is disengaged from the C-shaped guide rod.

[0007] Furthermore, the upper end of the column is connected to the handle.

[0008] Furthermore, the outer diameter of the insertion tube is larger than the outer diameter of the branch pipe, and the branch pipe is connected to the top of the insertion tube.

[0009] Furthermore, the top diameter of the conical head is larger than the outer diameter of the insertion tube.

[0010] Furthermore, the inner wall of the insertion tube is provided with a groove, and the side of the sliding rod is provided with a slider, which slides along the groove.

[0011] Furthermore, the main pipeline is connected to the filter tank, and the filter tank is equipped with a filter screen.

[0012] Furthermore, the main pipeline is equipped with a solenoid valve, which is signal-connected to a controller, and the controller is signal-connected to a humidity sensor, which is located in the soil.

[0013] Furthermore, the filter canister includes a shell, a filter screen, and a lid. The shell has an opening, the lid is threadedly connected to the opening, and the filter screen is disposed inside the shell.

[0014] The beneficial effects of this invention are as follows: A water flow channel is provided between the insertion tube and the sliding rod. Water flows into the insertion tube through a valve and then flows out from the lower opening of the insertion tube, providing drip irrigation to the roots of the fruit seedlings. The sliding rod of the drip irrigation head is inserted into the insertion tube, with the conical head fitting against the bottom of the insertion tube. The drip irrigation head is then inserted into the soil layer for easy insertion. Next, the insertion tube is pulled upwards a short distance to increase the distance between the bottom of the insertion tube and the conical head, allowing the drip irrigation water to drain more smoothly. During drip irrigation, water drips directly from the insertion tube into the soil around the roots of the fruit seedlings, facilitating direct water absorption by the seedlings. The water outlet is located inside the soil, reducing surface water evaporation and achieving water-saving effects. Attached Figure Description

[0023] Example 1

[0024] Please refer to the attached document. Figures 1-3This application provides a water-saving drip irrigation device for fruit seedlings, including a main pipe 1, branch pipes 2, and drip heads 3. The main pipe 1 has several branch pipes 2, and each branch pipe 2 has a drip head 3. The drip head 3 includes a valve 4, an insertion tube 5, a conical head 6, and a sliding rod 7. The upper end of the conical head 6 has the sliding rod 7, the diameter of which is smaller than the inner diameter of the insertion tube 5. The sliding rod 7 is slidably connected to the insertion tube 5, and a water flow channel is provided between the sliding rod 7 and the insertion tube 5. The insertion tube 5 has the valve 4, which is connected to the branch pipes 2. The main pipe 1 supplies water, and the water flows through the branch pipes 2 to the drip head 3. The dripping speed is controlled by the valve 4 of the drip head 3; a larger opening of the valve 4 results in a higher dripping speed, and a smaller opening of the valve 4 results in a lower dripping speed. A water flow channel is provided between the insertion tube 5 and the sliding rod 7. Water flows into the insertion tube 5 through the valve 4 and then flows out from the lower opening of the insertion tube 5 to drip irrigate the roots of the fruit seedlings. The sliding rod 7 of the drip irrigation head 3 is inserted into the insertion tube 5, with the conical head 6 fitting against the bottom of the insertion tube 5. The drip irrigation head 3 is then inserted into the soil layer for easy insertion. Next, the insertion tube 5 is pulled upwards a short distance, for example, 1-3 cm, to increase the distance between the bottom of the insertion tube 5 and the conical head 6, allowing the drip irrigation water to drain more smoothly. In this invention, water drips directly from the insertion tube 5 into the soil around the roots of the fruit seedlings, facilitating direct water absorption by the seedlings. The water outlet is located inside the soil, reducing surface water evaporation and achieving water-saving effects.

[0025] The component in this invention for controlling the drip irrigation speed is a valve 4, which is connected to an insertion tube 5. The insertion tube 5 extends into the soil layer. During insertion, a conical head 6 blocks the lower opening of the insertion tube 5, preventing soil from blocking the opening. In rainy weather, mud and water splashed from the soil surface will not enter the valve 4 and the insertion tube 5, effectively keeping the valve 4 unobstructed and maintaining a stable water flow.

[0026] Specifically, the drip irrigation head 3 also includes a column 8, a horizontal rod 9, and a C-shaped guide rod. The column 8 is connected to the horizontal rod 9, and the horizontal rod 9 is equipped with the C-shaped guide rod, with the notch of the C-shaped guide rod facing downwards. The C-shaped guide rod is slidably connected to the insertion tube 7. When the lower end of the insertion tube 7 is directly below the column 8, the upper end of the insertion tube 7 is detached from the C-shaped guide rod. The bottom of the column 8 is brought close to the roots of the seedling, and the column 8 is held upright. Then, the insertion tube 7 is slid along the C-shaped guide rod until the upper end of the insertion tube 7 is detached from the C-shaped guide rod. At this point, the lower end of the insertion tube 7 moves below the column 8, i.e., it is inserted into the bottom of the seedling. Through the cooperation of the above structure, the insertion tube 7 can be inserted into the seedling from the side at an inclined angle, drip irrigation downwards, which can reduce the loss of the soil surface. Furthermore, the inclined insertion from the side can reduce damage to the root system caused by the insertion tube 7. The upright post 8, the horizontal bar 9, and the C-shaped guide rod can be reused. That is, after inserting one drip head 3, the upright post 8, the horizontal bar 9, and the C-shaped guide rod can be used for another drip head 3, reducing production costs.

[0027] Specifically, the upper end of the column 8 is connected to the handle 11 for easy operation by staff.

[0028] Specifically, the outer diameter of the insertion tube 7 is larger than the outer diameter of the branch pipe 2, and the branch pipe 2 is connected to the top of the insertion tube 7. The insertion tube 7 slides along the C-shaped guide rod, and after the insertion tube 7 disengages from the C-shaped guide rod, the branch pipe 2 can pass through the notch in the C-shaped guide rod.

[0029] Specifically, the top diameter of the conical head 6 is larger than the outer diameter of the insertion tube 7. After the conical head 6 is inserted into the soil, when the insertion tube 7 retracts a certain distance upwards, the conical head 6 remains in its original position, and the distance between the insertion tube 7 and the conical head 6 increases, allowing water to flow out more smoothly.

[0030] Specifically, the inner wall of the insertion tube 7 is provided with a groove 12, and the side of the sliding rod 7 is provided with a slider 13, which slides along the groove 12. The slider 13 slides up and down in the groove 12, and the sliding rod 7 cannot be disengaged from the insertion tube 7. After the drip head 3 is pulled out, the insertion tube 7 and the conical head 6 can be removed, so that the drip head 3 can be reused.

[0031] Example 2

[0032] Please refer to the attached document. Figure 4 The difference between this embodiment and Embodiment 1 is that the main pipe 1 is connected to the filter tank 14, and the filter tank 14 is equipped with a filter screen 15. The filter tank 14 can filter impurities in the water, prevent the valve 4 from becoming clogged, and ensure that the water output from each drip head 3 is uniform.

[0033] Specifically, the main pipeline 1 is equipped with a solenoid valve 18, which is signal-connected to a controller 19. The controller 19 is signal-connected to a humidity sensor 20, which is located within the soil. The humidity sensor 20 detects the soil moisture of the seedling roots and transmits the soil moisture signal to the controller 19. When the soil moisture exceeds a preset value, the controller 19 controls the solenoid valve 18 to close, stopping drip irrigation. When the soil moisture is low, the controller 19 controls the solenoid valve 18 to open, initiating drip irrigation. This invention can open and close valve 4 according to soil moisture, improving water-saving efficiency.

[0034] Specifically, the filter canister 14 includes a housing 16, a filter screen 15, and a cover 17. The housing 16 has an opening, and the cover 17 is threadedly connected to the opening. The filter screen 15 is disposed inside the housing 16. The cover 17 can be removed from the housing 16. After the cover 17 is removed, the opening of the housing 16 is opened, allowing the filter screen 15 to be replaced or removed for cleaning.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
