[0026] 5. The drip irrigation device for agricultural cultivation allows the fertilizer to stay on the curved plate. When the drip irrigation pipe drips water downward, the water droplets will wrap the fertilizer and slide from the curved plate to the soil. On the one hand, it can prevent the fertilizer from being too concentrated, and on the other hand, it can ensure that the fertilizer can be fully decomposed and released to achieve better fertilization effect.

[0038] Embodiment 1:

[0039] Reference Figure 1-Figure 8A drip irrigation device for agricultural cultivation comprises a water tank 1 for storing water, and also comprises: a circulation pump 2 fixedly mounted on the water tank 1, wherein the input end of the circulation pump 2 extends into the water tank 1, and the output end of the circulation pump 2 is fixedly mounted with a U-shaped tube 3, and the output end of the U-shaped tube 3 extends into the water tank 1; a vertical pipe 5 fixedly connected to the lower end of the U-shaped tube 3, wherein the lower end of the vertical pipe 5 is fixedly connected with an upper annular cover 4, and the lower port of the upper annular cover 4 is rotatably connected with a lower annular cover 6, and the upper annular cover 4 and the lower annular cover 6 are combined into an annular tube, and a drip irrigation pipe 7 for dripping water downward is installed on the lower annular cover 6, and the drip irrigation pipe 7 is connected with the lower annular cover 6 through a connecting pipe 8, and a driving part for driving the lower annular cover 6 to rotate is provided on the upper annular cover 4.

[0040] When in use, the annular tube composed of the upper annular cover 4 and the lower annular cover 6 is surrounded around the plants, and then the circulation pump 2 is started. The circulation pump 2 will circulate the water in the water tank 1 to the U-shaped tube 3 continuously, and the water in the U-shaped tube 3 will flow into the annular tube composed of the upper annular cover 4 and the lower annular cover 6 through the vertical pipe 5, and then enter the drip irrigation pipe 7 through the connecting pipe 8, and finally drip from the bottom of the drip irrigation pipe 7 into the soil where the plants are planted. During this period, the driving part will drive the lower annular cover 6 to rotate, and the lower annular cover 6 will drive the drip irrigation pipe 7 to revolve around the plants, and the drip irrigation pipe 7 will change the drip irrigation position at different times, so as to improve the uniformity of watering, and it is not easy to cause the soil to become compacted, so as to achieve a better effect of plant cultivation.

[0041] Embodiment 2:

[0042] Reference Figure 1-Figure 5 , which is basically the same as the first embodiment, and further discloses a specific implementation scheme of the driving unit.

[0043] The above-mentioned driving part includes an annular protective cover 33 fixedly connected to the outer wall of the upper annular cover 4, and a vertical shaft 9 is rotatably connected to the annular protective cover 33, wherein a driving gear 11 is fixedly installed at the lower end of the vertical shaft 9, and a first annular gear 12 meshingly connected to the driving gear 11 is fixedly installed on the outer wall of the lower annular cover 6, and a fan blade 10 is fixedly installed on the upper end of the vertical shaft 9, and the fan blade 10 is eccentrically installed in the U-shaped tube 3, and the annular protective cover 33 is used to isolate the driving gear 11 and the first annular gear 12.

[0044] Specifically, during drip irrigation, the continuously flowing water in the U-shaped tube 3 will drive the fan blades 10 to rotate, and the fan blades 10 will drive the driving gear 11 to rotate through the vertical shaft 9, and the driving gear 11 will drive the first ring gear 12 to rotate, and the first ring gear 12 will drive the lower annular cover 6 to rotate, and the lower annular cover 6 will drive the strip cover 13 and the drip irrigation pipe 7 to revolve around the plant, and the drip irrigation pipe 7 will change the drip irrigation position at different times, thereby improving the uniformity of watering and preventing the soil from becoming compacted, thereby achieving a better effect of plant cultivation.

[0045] Embodiment three:

[0046] Reference Figure 4 , Figure 6 as well as Figure 7 , which is basically the same as the second embodiment, and further, a specific implementation scheme for making the drip irrigation pipe 7 intermittently approach or move away from the plant is specifically added.

[0047] The lower end of the above-mentioned lower annular cover 6 is fixedly connected to a strip cover 13, the lower end of the strip cover 13 is provided with an opening, and the strip cover 13 is perpendicular to the axis of the lower annular cover 6, a slide 17 is slidably installed in the strip cover 13, and the drip irrigation pipe 7 is fixedly installed on the slide 17. A translation part for driving the slide 17 to slide is provided in the strip cover 13, and the translation part includes a reciprocating screw 14 rotatably installed in the strip cover 13, and the slide 17 is installed on the outer wall of the reciprocating screw 14. When the reciprocating screw 14 continues to rotate, the slide 17 will slide back and forth along the outer wall of the reciprocating screw 14, wherein a driven gear 15 is fixedly installed at one end of the reciprocating screw 14, and a second ring gear 16 meshingly connected to the driven gear 15 is fixedly installed on the inner wall of the annular protective cover 33.

[0048] Specifically, when the strip cover 13 revolves around the plant, the strip cover 13 will drive the driven gear 15 to roll along the second ring gear 16, and the second ring gear 16 will drive the driven gear 15 to rotate, and the driven gear 15 will drive the reciprocating screw 14 to rotate, and the reciprocating screw 14 will drive the slide 17 to slide back and forth along the inner wall of the strip cover 13, so that the slide 17 will drive the drip irrigation pipe 7 to indirectly approach or move away from the plant, so that the water dripping from the drip irrigation pipe 7 is more dispersed and even.

[0049] The lower end of the slide 17 is fixedly connected to a support plate 18 located on both sides of the drip irrigation pipe 7. Swinging plates 19 are rotatably installed on the two support plates 18 through a rotating shaft 22. The lower ends of the two swinging plates 19 are fixedly connected to loosening rods 20. The loosening rods 20 are used to loosen the soil, and their functions are similar to those of a hoe or a rake. The opposite surfaces of the two support plates 18 are fixedly connected to limit plates 21. The limit plates 21 are used to limit the support plates 18 from swinging in the direction of the limit plates 21, and the limit plates 21 are perpendicular to the ground.

[0050] Specifically, during the reciprocating sliding of the slide 17 along the strip cover 13, the slide 17 will also drive the loosening rod 20 to move synchronously through the support plate 18. When the loosening rod 20 approaches the plant, the swing plate 19 close to the plant will be limited by the limit plate 21, and the loosening rod 20 will basically remain in a vertical state, thereby loosening the soil according to the principle of a hoe, and the swing plate 19 away from the plant is not blocked by the limit plate 21, so it will swing in the direction away from the drip irrigation pipe 7 under the push of the soil, and the loosening rod 20 at the lower end of the swing plate 19 will not loosen the soil. On the contrary, when the slide 17 slides in the opposite direction, the two loosening rods 20 will exchange states. Therefore, when the slide 17 drives the drip irrigation pipe 7 to move, the loosening rod 20 will loosen the soil in advance. On the one hand, it can prevent the soil from caking, and on the other hand, it can make the water droplets moisten the soil more evenly.

[0051] Embodiment 4:

[0052] Reference Figure 6-Figure 8 , which is basically the same as Example 3, and further, a specific implementation plan for fertilizing the soil is specifically added.

[0053] A storage box 23 for storing granular fertilizer is fixedly installed on the above-mentioned slide 17. The diameter of the stored granular fertilizer is 1mm-3mm. A discharge pipe 24 for discharging the granular fertilizer is fixedly provided at the lower end of the storage box 23. A vertical rod 25 extending into the discharge pipe 24 is rotatably installed on the storage box 23. A spiral piece 26 is fixedly installed on the outer wall of the vertical rod 25. A passive gear 27 is installed on the top of the vertical rod 25. A frame 28 is fixedly connected to the strip cover 13, and a rack 29 is fixedly installed on the frame 28.

[0054] During the sliding of the slide 17, the slide 17 will also drive the storage box 23 to slide horizontally, and the storage box 23 will drive the discharge pipe 24 and the passive gear 27 to move synchronously. When the passive gear 27 slides over the rack 29, the passive gear 27 will drive the vertical rod 25 to rotate, and the vertical rod 25 will drive the spiral piece 26 at the bottom to rotate, and the spiral piece 26 will push the fertilizer in the storage box 23 to be transported into the discharge pipe 24, and part of the fertilizer in the discharge pipe 24 will be discharged from its bottom to the soil, thereby automatically completing the fertilization work of the fertilizer, and will more evenly sprinkle the fertilizer around the plants, thereby improving the uniformity of the fertilizer in the soil and making the plant cultivation effect better. In practice, the fertilizer particles have a slow release effect relative to the fertilizer liquid, which is convenient for the soil and plants to absorb.

[0055] The lower end of the discharge pipe 24 is fixedly connected with a downwardly inclined flow guide cover 30, the end of the flow guide cover 30 is fixedly connected with an inclined plate 31, the end of the inclined plate 31 is fixedly connected with an arc plate 32 for receiving granular fertilizer, the arc plate 32 is made of a ceramic material with a smooth surface and a certain hydrophobicity, and the arc plate 32 is located directly below the drip irrigation pipe 7.

[0056] Specifically, when the fertilizer particles fall downward, the fertilizer will fall onto the guide cover 30, then roll along the inclined guide cover 30 to the inclined plate 31, and finally stay on the curved plate 32. When the drip irrigation pipe 7 drips water downward, the water droplets dripping downward will just drip onto the curved plate 32, and the water droplets will wrap the fertilizer and slide from the curved plate 32 to the soil. On the one hand, it can prevent the fertilizer from being too concentrated, and on the other hand, it can ensure that the fertilizer can be fully decomposed and released to achieve a better fertilization effect.

[0057] In order to prevent the fertilizer from not being carried away by the water drops, the amount of fertilizer needs to be controlled at one to two, and the water drops dripped from the drip irrigation tube 7 need to be slightly inclined to the fertilizer, so that the water drops can slide off the curved plate 32 under the action of inertia, thereby taking away the granular fertilizer. Of course, even if the fertilizer cannot be taken away, the fertilizer will eventually be taken away or melted away under the action of multiple water drops.

[0058] A drip irrigation method for agricultural cultivation, the operating steps are as follows:

[0059] Step 1: surround the plant with the annular tube composed of the upper annular cover 4 and the lower annular cover 6;

[0060] Step 2: Circulate the water in the water tank 1 into the U-shaped tube 3 continuously;

[0061] Step 3: Make the lower annular cover 6 drive the drip irrigation pipe 7 to revolve around the plant;

[0062] Step 4: Make the drip irrigation tube 7 intermittently approach or move away from the plant;

[0063] Step 5: During drip irrigation, water drops wrapped with granular fertilizer fall onto the soil.

[0064] The drip irrigation device for agricultural cultivation, when in use, surrounds the plants with the annular tube composed of the upper annular cover 4 and the lower annular cover 6, and then starts the circulation pump 2, the circulation pump 2 will circulate the water in the water tank 1 to the U-shaped tube 3 continuously, and the water in the U-shaped tube 3 will flow into the annular tube composed of the upper annular cover 4 and the lower annular cover 6 through the vertical pipe 5, and then enter the drip irrigation pipe 7 through the connecting pipe 8, and finally drip from the bottom of the drip irrigation pipe 7 into the soil where the plants are planted, and during this period, the water continuously flowing in the U-shaped tube 3 will drive the fan blades 10 to rotate, the fan blades 10 will drive the driving gear 11 to rotate through the vertical shaft 9, the driving gear 11 will drive the first annular gear 12 to rotate, the first annular gear 12 will drive the lower annular cover 6 to rotate, the lower annular cover 6 will drive the strip cover 13 and the drip irrigation pipe 7 to revolve around the plants, the drip irrigation pipe 7 will change the drip irrigation position differently, so as to improve the uniformity of watering, and it is not easy to cause the soil to be hardened, so as to achieve a better effect of plant cultivation.

[0065] When the strip cover 13 revolves around the plant, the strip cover 13 drives the driven gear 15 to roll along the second ring gear 16, and the second ring gear 16 drives the driven gear 15 to rotate, and the driven gear 15 drives the reciprocating screw 14 to rotate, and the reciprocating screw 14 drives the slide 17 to slide back and forth along the inner wall of the strip cover 13, so that the slide 17 drives the drip irrigation pipe 7 to indirectly approach or move away from the plant, so that the water dripping from the drip irrigation pipe 7 is more dispersed and evenly distributed.

[0066] While the slide 17 slides back and forth along the strip cover 13, the slide 17 will also drive the loosening rod 20 to move synchronously through the support plate 18. When the loosening rod 20 approaches the plant, the swing plate 19 close to the plant will be limited by the limit plate 21, and the loosening rod 20 will basically remain in a vertical state, thereby loosening the soil with the principle of a hoe, and the swing plate 19 away from the plant is not blocked by the limit plate 21, so it will swing in the direction away from the drip irrigation pipe 7 under the push of the soil, and the loosening rod 20 at the lower end of the swing plate 19 will not loosen the soil. On the contrary, when the slide 17 slides in the opposite direction, the two loosening rods 20 will exchange states, so when the slide 17 drives the drip irrigation pipe 7 to move, the loosening rod 20 will loosen the soil in advance, which can prevent the soil from caking on the one hand, and make the water droplets wet the soil more evenly on the other hand.

[0067] During the sliding of the slide 17, the slide 17 will also drive the storage box 23 to slide horizontally, and the storage box 23 will drive the discharge pipe 24 and the passive gear 27 to move synchronously. When the passive gear 27 slides over the rack 29, the passive gear 27 will drive the vertical rod 25 to rotate, and the vertical rod 25 will drive the spiral piece 26 at the bottom to rotate, and the spiral piece 26 will push the fertilizer in the storage box 23 to be transported into the discharge pipe 24, and part of the fertilizer in the discharge pipe 24 will be discharged from its bottom to the soil, thereby automatically completing the fertilization work of the fertilizer, and will more evenly sprinkle the fertilizer around the plants, improve the uniformity of the fertilizer in the soil, and make the plant cultivation effect better. In practice, the fertilizer particles have a slow release effect relative to the fertilizer liquid, which is convenient for the soil and plants to absorb.

[0068] When the fertilizer particles fall downward, the fertilizer will fall onto the guide cover 30, then roll down to the inclined plate 31 along the inclined guide cover 30, and finally stay on the curved plate 32. When the drip irrigation pipe 7 drips water downward, the water droplets dripping downward will just drip onto the curved plate 32, and the water droplets will wrap the fertilizer and slide from the curved plate 32 to the soil. On the one hand, it can prevent the fertilizer from being too concentrated, and on the other hand, it can ensure that the fertilizer can be fully decomposed and released to achieve a better fertilization effect.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
