Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, and more specifically, to an integrated drip irrigation device for water and fertilizer. Background Technology

[0002] Drip irrigation is one of the most effective water-saving irrigation methods in arid and water-scarce areas. It uses plastic pipes to deliver water to the roots of crops through orifices or drippers on capillary tubes with a diameter of about 10mm for localized irrigation. It can be widely used for fruit trees, vegetables, cash crops, and greenhouse irrigation.

[0003] Chinese invention patent CN119655160A discloses an integrated water and fertilizer drip irrigation device, including a mobile box with a shock-absorbing plate inside. The shock-absorbing plate is connected to the mobile box via a shock-absorbing structure. The bottom of the mobile box is equipped with wheels. A water and fertilizer bucket and a water tank are mounted on the shock-absorbing plate. The water tank is connected to the water and fertilizer bucket via a water pump. A stirring component is installed inside the water and fertilizer bucket. A frame is installed on the side of the mobile box. The technical solution of the above invention uses an integrated drip irrigation device with mobile function, combined with a drip irrigation component that automatically inserts into the soil to complete the task of water and fertilizer drip irrigation to plant roots. It does not require installation or disassembly, making it more convenient to use and greatly improving the efficiency of drip irrigation.

[0004] However, in the above-mentioned technical solutions, the drip irrigation structure is set on a mobile box, which can only irrigate one crop at a time, resulting in low efficiency. Furthermore, during drip irrigation, the mobile box needs to move the drip irrigation structure within the planting area on the ground. The mobile box is relatively large and can easily damage the stems or leaves of the plants in the planting area.

[0005] Chinese utility model patent CN219893850U discloses an integrated water and fertilizer drip irrigation device, including a drip irrigation cart with a storage tank on the cart. Two symmetrical feeding boxes are located at the top of the storage tank, each with a feeding port for adding waste material. The drip irrigation cart has a water inlet for adding water. A drip irrigation mechanism is located between the drip irrigation cart and the feeding boxes. An adjustment mechanism is located inside the drip irrigation cart. A rotatable feeding shaft in the drip irrigation mechanism drives a feeding auger to rotate, allowing fertilizer from the feeding boxes to be added to the feeding chamber through a feeding cylinder for easy mixing with water. A filter plate filters impurities, preventing blockage of the drip irrigation system.

[0006] Although the drip irrigation device in the above technical solution can achieve the function of adjusting the drip irrigation area, the extension distance of its drip irrigation structure is too long. When the drip irrigation trolley moves, the drip irrigation structure must be retracted first to avoid damage to the plant stem, which makes it impractical. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] Please see Figure 1-5 As shown, this utility model embodiment provides an integrated water and fertilizer drip irrigation device, including a water and fertilizer tank 1, a lifting component 2, a diversion component 3, and a drip irrigation component 4, wherein:

[0048] The water and fertilizer tank 1 includes a tank body 11, casters 13 and a handle 14. The casters 13 are installed at the bottom of the tank body 11, and the handle 14 is fixed on one side of the length of the tank body 11. The casters 13 make it easy to move the tank body 11, so that the user can hold the handle 14 and push the tank body 11 to move.

[0049] The lifting component 2 includes an electric push rod 21, a slide rail 22, and a fixing plate 23. The electric push rod 21 is vertically fixed on both sides of the box body 11 in the width direction. The slide rail 22 is located above the box body 11. The fixing plate 23 is installed inside the slide rail 22 and is fixedly connected to the top of the electric push rod 21. This allows the lifting component 2 to raise the position of the slide rail 22 when the height of the plant is greater than the distance from the top surface of the box body 11 to the ground, thereby avoiding damage to the stems and leaves of the plant caused by the slide rail 22.

[0050] The drainage component 3 includes a drainage pipe 31 and a connecting pipe 32. The drainage pipe 31 is installed on the top of the box 11, and several connecting pipes 32 are installed on the inner side of the slide rail 22. The connecting pipes 32 are connected to the drainage pipe 31, so that the water and fertilizer solution in the box 11 can be transported to each connecting pipe 32 through the drainage pipe 31, thereby simultaneously transporting the liquid to multiple locations.

[0051] The drip irrigation component 4 includes a T-shaped pipe 41, a liquid outlet pipe 42, and an extension component 43. The T-shaped pipe 41 is installed at the bottom of the connecting pipe 32, and the two liquid outlet pipes 42 are slidably inserted at both ends of the transverse section of the T-shaped pipe 41. The extension component 43 is used to adjust the position of the liquid outlet pipe 42 inside the T-shaped pipe 41, so that the water and fertilizer solution can be introduced into the liquid outlet pipe 42 through the T-shaped pipe 41, thereby enabling the liquid outlet pipe 42 to drip irrigate the plants.

[0052] As a further description of the above scheme, the top end of the T-tube 41 is provided with a necked section that is adapted to the inner wall of the connecting tube 32, and the outer wall of the necked section is provided with an external thread 411. The inner wall of the connecting tube 32 is provided with an internal thread 322 that is adapted to the external thread 411, so that the connection tube 32 and the T-tube 41 can be easily installed by using the cooperation of the internal thread 322 and the external thread 411.

[0053] Please see Figure 1-4 As shown, the slide rail 22 has an inverted U-shaped structure. The connecting pipe 32 is fixedly connected to sliders 321 on both sides near the inner wall of the slide rail 22. The inner wall of the slide rail 22 has a groove 222 that is adapted to slide the sliders 321. This allows the movement of the sliders 321 in the groove 222 to restrict the up and down movement of the connecting pipe 32 in the slide rail 22. By adjusting the position of the connecting pipe 32 in the slide rail 22, the drip irrigation component 4 can be adapted to fields with different planting densities.

[0054] Please see Figure 1-4 As shown, the integrated water and fertilizer drip irrigation device also includes a limiting component 5, wherein:

[0055] The limiting component 5 includes a limiting rod 52 and a positioning structure 51. The two limiting rods 52 are horizontally symmetrically installed on the vertical section of the T-tube 41. The positioning structure 51 is installed on the slide rail 22 to engage the limiting rods 52 to restrict the lateral movement of the T-tube 41, thereby achieving the fixed installation of the T-tube 41. This allows the T-tube 41 to move within the interval between two rows of plants when the box 11 moves along the ground boundary, thereby reducing the damage to the plant stem caused by the T-tube 41 during the movement.

[0056] Please see Figure 1-4As shown, the positioning structure 51 includes a bent plate 511 and a plug rod 512. The bent plate 511 has an inverted U-shaped structure. The plug rod 512 is installed on the inner top of the bent plate 511, and the inner wall width of the bent plate 511 is larger than the outer wall width of the slide rail 22. The top of the slide rail 22 is provided with several insertion holes 221 that are adapted to the sliding of the plug rod 512. The bottom of the bent plate 511 is provided with a notch 5111 that is adapted to the size of the limiting rod 52. The plug rod 512 on the bent plate 511 can be inserted into the slide rail 22 through the insertion holes 221, so that the bent plate 511 can be fitted onto the slide rail 22. Then, the limiting rod 52 can be engaged through the notch 5111 on the bent plate 511 to restrict the movement of the T-shaped tube 41 and the connecting tube 32.

[0057] Please see Figure 1 and Figure 5 As shown, the extension assembly 43 includes a fixed base 431, a rotating tube 432, and a threaded rod 435, wherein:

[0058] The fixed base 431 is fixed on both sides of the top surface of the transverse section of the T-tube 41. The rotating tube 432 is rotatably installed inside the fixed base 431. The threaded rod 435 is fixed on the top of the outlet tube 42. The threaded rod 435 has an L-shaped structure, and a threaded hole is opened transversely inside the rotating tube 432. One end of the threaded rod 435 is connected to the outlet tube 42, and the other end is suitable for threading through the threaded hole of the rotating tube 432. This allows the rotating tube 432 to rotate within the fixed base 431, thereby driving the threaded rod 435 to move laterally and adjusting the position of the outlet tube 42 within the transverse section of the T-tube 41.

[0059] Please see Figure 5 As shown, a through hole is horizontally opened inside the fixed base 431, and the inner diameter of the through hole is larger than the outer diameter of the rotating tube 432. A limit ring 433 is provided on the outer periphery of the rotating tube 432. An annular groove that slides and adapts to the limit ring 433 is opened on the inner wall of the through hole of the fixed base 431. A rotating inner liner 434 that adapts to the outer wall of the rotating tube 432 is fixedly connected to the inner wall of the through hole of the fixed base 431. The rotating tube 432 can be installed into the fixed base 431 through the through hole, and the limit ring 433 can cooperate with the annular groove to restrict the movement of the rotating tube 432. The rotating inner liner 434 can keep the rotation of the rotating tube 432 smooth and stable.

[0060] Please see Figure 1 and Figure 5As shown, a sealing sleeve 421 that fits the inner wall of the T-tube 41 is fixedly fitted on the outer wall of the outlet pipe 42. Valves 412 located on both sides of the vertical section of the T-tube 41 are installed in the transverse section of the T-tube 41. The sealing sleeve 421 is used to prevent liquid from seeping out from the gap between the transverse section of the T-tube 41 and the outlet pipe 42. The valves 412 can control the opening and closing of the transverse section of the T-tube 41 so as to adjust whether the outlet pipe 42 is used as needed.

[0061] When the number of rows of plants in the field is even, drip irrigation can be achieved by simply adjusting the number and position of the T-tubes 41 as needed. However, if the number of rows of plants in the field is odd, one end of the outermost horizontal section of the T-tube 41 needs to be cut off using the valve 412 so that the number of liquid outlet tubes 42 in use corresponds to the number of rows of plants in the field.

[0062] Please see Figure 1 As shown, the integrated water and fertilizer drip irrigation device also includes a counterweight component 6, wherein:

[0063] The counterweight component 6 includes a fixing block 61 and a hook 62. The fixing block 61 is fixed to the end of the slide rail 22 away from the drip irrigation component 4. The hook 62 is installed at the bottom of the fixing block 61, and the counterweight is suspended on the hook 62. This facilitates the balance of the two sides of the box 11 in the width direction by suspending the counterweight on the hook 62, and prevents the box 11 from tipping over during the operation.

[0064] Please see Figure 1 As shown, the housing 11 is equipped with a stirring structure for mixing water and fertilizer, a conveying structure for conveying the water and fertilizer solution to the drainage pipe 31, and an electrical control component for controlling the operation of the stirring and conveying structures. The top of the housing 11 is provided with a feed inlet 12, which facilitates the addition of clean water and water-soluble fertilizer into the housing 11. The stirring structure ensures the efficiency and effectiveness of the mixing of fertilizer and clean water, while the conveying structure supplies the mixed water and fertilizer solution to the drainage pipe 31, allowing the water and fertilizer solution to flow along the drainage pipe 31, connecting pipe 32, T-shaped pipe 41, and outlet pipe 42, and finally flow out from the outlet pipe 42 to achieve drip irrigation.

[0065] Please see Figure 2 and Figure 4 As shown, a solenoid valve 323 is installed inside the connecting pipe 32, and a button 141 is provided on the grip section of the handle 14. Both the solenoid valve 323 and the button 141 are electrically connected to the electronic control component. This allows for convenient control of the on / off state of each solenoid valve 323 using the electronic control component, preventing the water and fertilizer solution from flowing out of the connecting pipe 32 without the T-shaped pipe 41 installed. Furthermore, the button 141 allows for adjustment of the conveying structure and solenoid valve 323 inside the housing 11 via the electronic control component, facilitating control of the start / stop of drip irrigation and the irrigation volume.

[0066] The working process of the above-mentioned integrated water and fertilizer drip irrigation device is as follows:

[0067] When using this integrated water and fertilizer drip irrigation device, firstly, the water and fertilizer tank 1 needs to be pushed into the boundary interval between the fields to be drip irrigated. Then, the number of rows of plants in the fields to be drip irrigated needs to be confirmed, and an appropriate number of T-shaped pipes 41 need to be prepared according to the number of rows of plants in the fields. Next, the spacing between the plants in the fields to be drip irrigated needs to be confirmed, and the T-shaped pipes 41 need to be installed on the slide rail 22 using the connecting pipe 32. At the same time, the positions of the connecting pipe 32 and the T-shaped pipes 41 on the slide rail 22 need to be adjusted so that the T-shaped pipes 41 are in the middle of two adjacent rows of plants. Then, the curved plate 511 can be sleeved on the slide rail 22, and the insertion rod 512 on the curved plate 511 can be inserted into the insertion hole 221 on the slide rail 22 to restrict the movement of the curved plate 511. The notch 5111 on the curved plate 511 can be used to engage the limiting rod 52 to restrict the movement of the T-shaped pipes 41 and the connecting pipe 32, thereby achieving the positioning and installation of the T-shaped pipes 41.

[0068] Then, the position of the outlet pipe 42 in the transverse section of the T-tube 41 needs to be adjusted according to the actual situation. By rotating the pipe 432 in the fixed seat 431, the threaded rod 435 is moved laterally, thereby adjusting the position of the outlet pipe 42 in the transverse section of the T-tube 41 until the outlet port of the outlet pipe 42 is directly facing the root of the plant. Combined with the control of the valve 412, each activated outlet pipe 42 can correspond to the root of a plant. After that, as long as the water and fertilizer are sufficient, just press the button 141 on the handle 14 to cooperate with the electronic control components to control the conveying structure and solenoid valve 323 in the box 11, so that the water and fertilizer solution in the box 11 flows into each connecting pipe 32 along the drainage pipe 31, and flows through the connecting pipe 32 and the T-tube 41 to the outlet pipe 42 to flow out, realizing drip irrigation operation and achieving the effect of drip irrigation operation on multiple plants at the same time.

[0069] In addition, when the water and fertilizer tank 1 moves between the boundaries of the fields, it can adjust the position of the drip irrigation operation, thus facilitating drip irrigation for plants in different locations.

[0070] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
