Description

Technical Field

[0001] The invention relates to the technical field of irrigation equipment, and in particular to a seedling drip irrigation device and a drip irrigation method thereof. Background Art

[0002] The cultivation of trees in municipal gardens usually adopts the form of centralized seedling raising and transplanting. When raising seedlings, drip irrigation technology is usually used for irrigation. Drip irrigation technology has excellent water-saving performance and can induce the root system of seedlings to develop in shallow soil, thereby reducing the excavation depth required for transplantation and reducing the difficulty of operation.

[0003] Drip irrigation is to transport water with a certain pressure to the capillary tube through the drip irrigation pipe system, and then drip the water into the soil evenly and slowly in the form of water drops through the emitters such as drippers, orifices or drip irrigation belts installed on the capillary tube. Drip irrigation is a local irrigation technology. Due to the small flow rate of the dripper, the water slowly penetrates into the soil. Therefore, under drip irrigation conditions, except for the soil moisture immediately below the dripper, which is in a saturated state, other parts are in an unsaturated state. The soil moisture mainly infiltrates and diffuses with the help of capillary tension. Drip irrigation has basically no infiltration loss, the wet area of ​​the soil surface is small, and the evaporation loss is effectively reduced, with obvious water-saving effects.

[0004] Traditional drip irrigation technology generally uses canvas pipes, which are highly flexible and easy to coil. During drip irrigation, although the flow rate of water in a single drip irrigation hole is small, the front end of the pipe bears most of the water volume of the drip irrigation hole, so it still has a large flow rate. At this position, the canvas pipe is easily impacted by the water flow in the inner cavity and then partially displaced or twisted, causing the drip irrigation holes originally aimed at the seedlings to move away from the seedlings or point to a direction other than where the seedlings are located, reducing the drip irrigation efficiency and water-saving performance. Secondly, when the soil layer where the pipe is placed has a slope, the pipe will also rotate partially under the weight of the water flow inside the pipe, causing the drip irrigation holes originally aimed at the seedlings to point to other places. Summary of the invention

[0053] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0054] Reference Figure 1 A seedling drip irrigation device includes a pump body 1, a water pumping pipe 2 and a drainage pipeline, wherein the water pumping pipe 2 and the drainage pipeline are respectively connected to and communicated with the water inlet and the water outlet of the pump body 1. The end of the water pumping pipe 2 away from the pump body 1 is connected to and communicated with a water source, such as a fresh water source such as a river, a lake or a reservoir. The pump body 1 is used to extract irrigation water from the water source through the water pumping pipe 2, and then press the irrigation water into the drainage pipeline.

[0055] Reference Figure 1 The drainage pipeline includes a drainage main pipe 3 and a drainage side pipe 4, and the end of the drainage side pipe 4 is connected and communicated with the first flow guide hole 31 on the side of the drainage main pipe 3. The drainage main pipe 3 and the drainage side pipe 4 are connected in a Feng shape or an F shape.

[0056] Reference Figure 2 A first mounting ring 32 is sealed and fixedly installed in the first guide hole 31 (for example, by annular clamping and hot melt adhesive sealing), and a first mounting piece 41 is clamped at the end of the drainage side pipe 4. The first mounting ring 32 is detachably connected to the first mounting piece 41 through threads.

[0057] Reference Figure 3 and Figure 4The drainage side pipe 4 is provided with a second guide hole 42, and a plurality of the second guide holes 42 are provided. The second guide holes 42 are arranged at equal intervals along the length direction of the drainage side pipe 4 (for example, the installation interval is 0.3 meters, 0.5 meters, 1 meter, etc.). A drip irrigation assembly 5 is installed at each guide hole position.

[0058] Reference Figure 3 to Figure 5 The drip irrigation assembly 5 includes a plugging member 51, a receiving member 52, a flip plate 53 and a drip irrigation pipe 54; the plugging member 51 is sealed and fixedly installed in the second guide hole 42. The edge of the plugging member 51 is provided with a concave ring 512 adapted to the second guide hole 42; the edge of the second guide hole 42 is clamped in the concave ring 512, and a sealing ring or a sealant is provided at the clamping position to prevent water leakage. The plugging member 51 is a circular plate-like structure, and a first adapting hole 511 is provided at the center of the plugging member 51. The drip irrigation pipe 54 is plugged and fixed in the first adapting hole 511 (for example, by threaded fixing installation); the receiving member 52 is installed on the lower surface of the plugging member 51 (for example, by bolts to be detachably installed), and the bottom surface of the receiving member 52 is provided with an upward groove 520, and the top surface of the upward groove 520 is provided with a second adapting hole 521. The second adapting hole 521 is sleeved on the surface of the drip irrigation pipe 54 and is clearance-matched to improve the smoothness of the receiving member 52 during assembly.

[0059] Reference Figure 5 , the lower end of the drip irrigation pipe 54 is placed on the top of the upper groove 520; when in use, since the plugging member 51 is placed horizontally and the drip irrigation pipe 54 is placed vertically, water drops fall on the lower part of the upper groove 520. When there is a protrusion formed by mud blocks on the soil surface and placed in the upper groove 520, water drops continuously drip longitudinally on the mud block protrusion, and the water content of the mud block protrusion continues to increase. Finally, the mud block protrusion loosens and collapses downward, thus moving away from the drip irrigation pipe 54, avoiding the mud block protrusion from blocking the upper groove 520 and the drip irrigation pipe 54, and further bringing convenience to the collection and storage of the drainage pipeline (no need to clean the adhered mud).

[0060] Reference Figure 3 to Figure 5 The lower end of the flip plate 53 is connected to one side of the receiving member 52 (for example, by integral molding or by bolts), and the other end of the flip plate 53 is fixedly connected to an extension fin 531 (for example, by integral molding or by bolts), and the extension fin 531 is provided with a plug hole 532, and a plug assembly 6 is plugged into the plug hole 532, and the plug assembly 6 can be pulled out from the plug hole 532. The plug hole 532 is used to limit the drainage side pipe 4 to prevent the drainage side pipe 4 from displacement.

[0061] Reference Figures 4 to 6The flip plate 53 is arc-shaped, and the flip plate 53 is adapted to the surface curvature of the drainage side pipe 4. The axis of the plug hole 532 is arranged parallel to the axis of the drip irrigation pipe 54, and the axis of the drip irrigation pipe 54 is arranged perpendicular to the blocking member 51. The drip irrigation pipe 54 is in the shape of a round straight tube. The plug assembly 6 includes a plug rod 61 and a reverse plug rod 62 fixedly connected in a T shape, the plug rod 61 is adapted to the plug hole 532, and the reverse plug rod 62 is adapted to the inner diameter of the drip irrigation pipe 54.

[0062] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 Since the drainage side pipe 4 is tubular, and the drainage side pipe 4 is usually made of a canvas water pipe that is easy to roll up and deform, the drainage side pipe 4 is usually partially twisted after being laid. When the drainage side pipe 4 is in a twisted state, the drip irrigation pipe 54 tilts sideways, that is, the water drops dripping through the drip irrigation pipe 54 and the soil soaked by the water drops are under direct sunlight, which will increase the evaporation of water, reduce the utilization rate of water, and cause waste; at the same time, if the drip irrigation pipe 54 points in the opposite direction of the sapling due to the twisting of the drainage side pipe 4, the drip irrigation position is far away from the sapling, which reduces the water absorption rate and causes waste. Therefore, after the drainage side pipe 4 is laid, the user inserts the plug rod 61 into the plug hole 532, and then rotates the plug rod 61 to flip the twisted part of the drainage side pipe 4 to a normal position, so that all the drip irrigation pipes 54 are in a vertical state and the drip irrigation pipes 54 are located directly below the drainage side pipe 4.

[0063] When the drip irrigation pipe 54 is located directly below the drainage side pipe 4: the drip irrigation pipe 54 is located in the shade formed by the drainage side pipe 4, which can prevent the dripping water droplets and the soil soaked by the water droplets from direct sunlight, thereby reducing evaporation and saving water resources; in the dripping water droplets and the soil soaked by the water droplets, evaporation of water is inevitable, but a space with better sealing (compared to the soil in the open area) can be formed between the upper groove 520 and the soil surface, reducing the loss rate of water vapor, increasing the humidity in the upper groove 520, and reducing the evaporation of water in the water droplets and the moist soil. The drip irrigation assembly 520 is used to increase the drainage speed, improve the infiltration rate, and save water resources; the originally dry soil is continuously infiltrated by the dripping water droplets, and the soil permeability is gradually reduced, which can increase the sealing of the space formed between the upper groove 520 and the soil surface, further increase the humidity, reduce evaporation, and save water resources; after the drainage side pipe 4 is passed through the water, the weight of the water in the drainage side pipe 4 is applied to the drip irrigation assembly 5, and the support part 522 presses the soil surface to deform the soil surface, further reducing the gap between the upper groove 520 and the soil surface, improving the sealing, reducing water evaporation, and saving water resources.

[0064] Reference Figure 4 and Figure 5The extended fin 531 points in the opposite direction of the drainage side pipe 4 to avoid wear between the extended fin 531 and the drainage side pipe 4, thereby increasing the service life of the drainage side pipe 4.

[0065] Reference Figure 8 to Figure 11 The lower surface of the receiving member 52 is provided with a support portion 522 (for example, connected by integral molding), and the bottom surface of the support portion 522 is provided with a limiting straight groove 523, which is adapted to the plug-in rod 61 and points to the flip plate 53. Figure 8 After the user inserts the reverse insertion rod 62 into the drip irrigation pipe 54, the drip irrigation pipe 54 can be blocked to stop the drip irrigation pipe 54 from dripping. Fig.11 After the reverse rod 62 is inserted into the drip irrigation pipe 54, the plug rod 61 is continuously pushed until the plug rod 61 is located in the limiting straight groove 523. The limiting straight groove 523 can prevent the plug rod 61 from rotating (rotating around the reverse rod 62 as the axis), thereby improving stability.

[0066] Reference Figures 9 to 11 The limiting straight groove 523 is located on the center plane 50 of the drip irrigation assembly 5; the plug hole 532 is located on one side of the center plane 50, so as to avoid space conflict between the two plug rods 61 when the two plug assemblies 6 are vertically installed, and achieve giving way.

[0067] Reference Figure 5 , Fig. 9 and Fig.10 The second adapter hole 521 is opened on one side of the center plane 50, the first adapter hole 511 and the second adapter hole 521 are coaxially arranged, and the drip irrigation pipe 54 is installed in the first adapter hole 511 and the second adapter hole 521, that is, the drip irrigation pipe 54 is located on one side of the center plane 50 to prevent water drops from falling on the plug rod 61 in the limiting straight groove 523, thereby achieving giving way.

[0068] Reference Figure 11 to Figure 14 The plug rod 61 includes a rod body and a plug tip 612 that are rotatably connected to each other; a straightening portion 613 and a sleeve ring 614 that is threadedly adapted to the straightening portion 613 are provided between the rod body and the plug tip 612. The straightening portion 613 is in a straight cylindrical shape and is fixedly installed at the end of the rod body 611 (for example, by bolts or by an integrated fixed connection); the sleeve ring 614 is hinged to the plug tip 612, and the inner wall of the sleeve ring 614 is connected to the outer wall of the straightening portion 613 by bolts. Fig.13 , rotate the rod body 611 or the plug tip 612 or the sleeve ring 614 until the straight portion 613 is screwed out of the inner cavity of the sleeve ring 614, which can release the lock, and then the plug tip 612 and the rod body 611 are relatively rotated; refer to Fig.14, rotate the rod body 611 or the plug-in tip 612 or the sleeve ring 614 until the straight portion 613 is inserted into the inner cavity of the sleeve ring 614, which can achieve locking and prevent relative rotation between the plug-in tip 612 and the rod body 611.

[0069] Reference Fig.16 The bottom of the limiting straight groove 523 is provided with a buckle portion 5231, which is fixedly connected to the side wall of the limiting straight groove 523 or the bottom surface of the support portion 522 (for example, by an integrated fixed connection or by a bolt fixed connection). The edge of the buckle portion 5231 is adapted to the rod body 611 to achieve the insertion of the rod body 611. Fig.15 and Fig.16 The buckle part 5231 applies a clamping force to the rod body 611, thereby preventing the reverse insertion rod 62 from being pushed out by water pressure; at the same time, when the plug-in tip 612 is plugged into the soil, the buckle part 5231 is used to realize the force transmission between the plug-in component 6 and the drip irrigation component 5, thereby improving the stability of the seedling drip irrigation device.

[0070] Reference Fig. 22 and Fig.23 The plug-in assembly 6 also includes a cross claw hoop 63, which includes a rectangular plate and four iron wires disposed at four sharp corners of the rectangular plate. When in use, the iron wires are bent to achieve hoop installation.

[0077] S6. Use the plug-in assembly a6a to install all the drip irrigation assemblies 5 on the upper surface of the soil.

[0078] During step S3, when the horizontal distance between the drip irrigation pipe 54 and the bottom end of the sapling trunk is less than 30 cm, it is determined to be close to the sapling; when the horizontal distance between the drip irrigation pipe 54 and the bottom end of the sapling trunk is greater than or equal to 30 cm, it is determined to be far away from the sapling.

[0079] Step S5 includes:

[0080] S5.1. Take several plug-in components b6b, rotate the rod body b611b until the straight portion b613b is removed from the inner cavity of the plug-in tip b612b (refer to 17);

[0081] S5.2, insert the reverse plug rod b62b into the drip irrigation pipe b54b; further push the plug assembly b6b until the rod body b611b is clamped in the limit straight groove 523, and the extended fin 531 and the plug tip b612b are respectively arranged on both sides of the drainage side pipe 4 (refer to Fig.18 );

[0091] The plug-in assembly b6b blocks the drip irrigation pipe b54b away from the saplings to avoid ineffective drip irrigation and save water.

[0092] In the present invention, the plug-in tip a612a and the plug-in tip b612b are respectively arranged on both sides of the drainage side pipe 4 to provide a pulling relay force, and the cross claw hoop 63 is used to provide a limiting force between the rod body a611a and the rod body b611b, thereby improving the installation stability of the drainage side pipe 4, avoiding displacement and twisting of the drainage side pipe 4 due to the impact of the inner cavity water flow, maintaining the vertical state of the drip irrigation pipe 54 and the sealing between the upper extension groove 520 and the soil surface, and avoiding the movement of the drip irrigation position, thereby ensuring the stable and reliable drip irrigation operation. The plug-in assembly a6a and the plug-in assembly b6b of the same structure can adapt to the installation of the drainage side pipe 4 at the position of the drip irrigation pipe 54 close to and far away from the seedling, and the difficulty of production and processing is reduced by increasing the number of parts with the same structure, and the mutual substitution in the subsequent use process is improved, so that the installation process is flexible and convenient.

[0093] A seedling drip irrigation method, further comprising:

[0094] Step S7: After the drip irrigation is completed, the seedling drip irrigation device is dismantled.

[0095] Reference Fig.21 , step S7 further comprises:

[0096] S7.1. Pull out the plug assembly a6a from the cross claw hoop 63 and the plug hole 532, and recycle and store;

[0097] S7.2, fix the end of the rod b611b away from the plug-in tip b612b on the soil surface (for example, by stepping on it), and then lift the drainage side pipe 4 to make the rod b611b come out of the limiting straight groove 523, and the reverse plug-in rod b62b is pulled out of the drip irrigation pipe b54b;

[0098] S7.3, restore the free state of the end of the rod b611b away from the plug-in tip b612b (for example, remove the foot force), grab the end of the rod b611b away from the plug-in tip b612b and horizontally rotate the rod b611b 180 degrees around the plug-in tip b612b, so that the rod b611b moves out from under the drainage side pipe 4;

[0099] S7.4. Rotate the rod body b611b so that the rod body b611b and the plug-in tip b612b are in a coaxial state. The user can grab the rod body b611b to easily pull the plug-in tip b612b out of the soil, and then recover and store the plug-in assembly b6b.

[0100] During step S7.3 and step S7.4, the rod body b611b is removed from the bottom of the drainage side pipe 4 and placed upright, which is convenient for users to grab and pull out upwards, which is convenient and labor-saving, away from the sharp plug tip b612b, and has high safety. The cross claw hoop 63 is used to provide a limiting force between the rod body a611a and the rod body b611b to improve the installation stability of the drainage side pipe 4; the rod body a611a and the rod body b611b are both straight rods with a constant diameter, so the rod body a611a and the rod body b611b can be easily pulled out from the cross claw hoop 63, making the present invention easy to load and unload.

[0101] Reference Fig.21 The top surface of the drainage side pipe 4 is provided with a marking line 401, and the drip irrigation assembly 5 is arranged on the bottom surface of the drainage side pipe 4. The marking line 401 is made of brightly colored fabric (such as red, yellow, blue, etc.) to make it highly visible. The user uses the plug assembly 6 to flip the drainage side pipe 4 until the marking line 401 is all facing upwards. The user can determine that the drip irrigation pipe 54 is in a vertical state, so as to simplify the operation steps and improve the layout accuracy.

[0102] The drip irrigation assembly 5 is arranged on the bottom surface of the drainage side pipe 4, so after removing the plug assembly 6, the user can grab one end of the drainage side pipe 4 and flip it upward to make the drainage side pipe 4 appear rolled up to reduce the space occupied and facilitate transportation and storage.

[0103] The present invention has a simple structure and convenient operation. The plug-in assembly 6 turns over the drainage side pipe 4 so that the drip irrigation pipe 54 is in the shade directly below the drainage side pipe 4 to avoid direct sunlight. At the same time, a relatively sealed space is formed between the upper groove 520 and the soil surface, and the evaporation of water droplets and water infiltrating the soil is reduced by increasing the humidity of the space. The plug-in assembly 6 limits the drainage side pipe 4 to prevent the drainage side pipe 4 from being displaced or twisted due to the impact of the inner cavity water flow, thereby preventing the drip irrigation position from moving away from the seedling or the drip irrigation pipe 54 from pointing to a direction other than the seedling (for example, obliquely upward), thereby improving the drip irrigation hit rate and water absorption rate. The present invention can realize the selective blocking and closing of the drip irrigation pipe 54, thereby avoiding the drip irrigation pipe 54 away from the seedling from performing ineffective drip irrigation and saving water resources. Compared with the traditional drip irrigation technology, the present invention has better water-saving performance, is convenient to load and unload, is safe and reliable, and has broad market prospects.
