Description

Technical Field

[0001] This utility model belongs to the field of fertilization, specifically relating to a ring-shaped distributed fertilization pipeline device. Background Technology

[0002] With the acceleration of agricultural modernization, precision fertilization has become the direction of industry development. Precision fertilization aims to accurately control the type, amount and application location of fertilizers based on factors such as crop growth needs and soil fertility, so as to achieve efficient resource utilization and high-quality and high-yield crops.

[0003] Currently, traditional pipeline fertilization devices mostly adopt a straight line or simple grid layout. After mixing fertilizer with water, it is transported to the nozzle through the pipeline to fertilize the plants. However, when using the fertilization pipeline, some fertilizer that is not dissolved in water is prone to clogging the nozzle. Existing fertilization pipelines are difficult to prevent nozzle clogging, cannot accelerate the centrifugal mixing of fertilizer and water during the delivery process, and have insufficient capacity to supply fertilizer to the roots in deep soil. Further improvements are needed. Utility Model Content

[0004] To overcome the problems of existing fertilization pipelines such as easy clogging of nozzles, poor fertilizer-water mixing effect, and insufficient fertilization capacity for deep soil roots, a ring-shaped distributed fertilization pipeline device is proposed.

[0005] The technical solution of this utility model is: a ring-shaped distributed fertilization pipeline device, including a water supply component, multiple outlet ends of the water supply component are respectively fixedly connected to the inlet ends of multiple connecting pipes, the outlet ends of the connecting pipes are connected to a carrier box, and a stirring cylinder is fixedly connected to the upper end of the carrier box.

[0006] The water outlet of the carrier box is connected to one end of the water inlet pipe, and the other end of the water inlet pipe is connected to the first annular pipe. The lower end of the first annular pipe is equipped with a fertilizer application component. One end of the first annular pipe is connected to the water supply pipe, and the other end of the water supply pipe is connected to a riser. The lower end of the riser is fixed with a nozzle.

[0007] The nozzle has a hollow disc-shaped structure, and the inside of the nozzle is connected to the inside of the riser. Multiple water spray holes are opened through the lower end of the nozzle.

[0008] A first rotating assembly is mounted on the mixing drum, a linkage assembly is mounted on the water inlet pipe, and a second rotating assembly is mounted on the riser pipe. The power output end of the first rotating assembly meshes with the power input end of the linkage assembly. The power output end of the linkage assembly meshes with the power input end of the second rotating assembly. A centrifugal wheel is fixedly connected to the power input end of the first rotating assembly. The centrifugal wheel is located inside the bearing box. A turntable is fixedly connected to the power output end of the third rotating rod. Brush bristles are fixedly connected to the lower end of the turntable. The lower end of the brush bristles is in contact with the bottom surface of the inner wall of the nozzle.

[0009] When the second rotating component rotates, the turntable rotates, causing the bristles to wipe the bottom surface of the inner wall of the nozzle;

[0010] The water supply unit is also equipped with a reverse pumping mechanism for pumping water from the connecting pipe.

[0011] Furthermore, the fertilization component includes a second support rod and a second annular tube; multiple second support rods are fixed to the side wall of the first annular tube, and the lower ends of the multiple second support rods are jointly fixed to the second annular tube. Both the second support rods and the second annular tube are hollow structures, and the interiors of the second support rods and the second annular tubes are interconnected. The lower end of the second annular tube is provided with evenly distributed water outlet holes.

[0012] Furthermore, the water supply assembly includes a water tank, a water pump, a water delivery pipe, and a first valve body; the inlet end of the connecting pipe is connected to the water delivery pipe, the water delivery pipe is equipped with the first valve body, the inlet end of the water delivery pipe is connected to the outlet end of the water pump, and the pumping end of the water pump is connected to the outlet end of the water tank through a pipe.

[0013] Furthermore, there is a gap between the side wall of the third rotating rod and the inner wall of the riser.

[0014] Furthermore, the first rotating assembly includes a first rotating rod and a first bevel gear; the first rotating rod is rotatably mounted through the upper end of the stirring drum, the first bevel gear is fixedly connected to the upper end of the first rotating rod, and a centrifugal wheel is fixedly connected to the lower end of the first rotating rod.

[0015] Furthermore, the linkage assembly includes a first support rod, a first fixed cylinder, a second rotating rod, and a second bevel gear; the upper end of the water inlet pipe is fixedly connected to the first support rod, the upper end of the first support rod is fixedly connected to the first fixed cylinder, the inner wall of the first fixed cylinder is rotatably mounted with the second rotating rod, and the two ends of the second rotating rod are respectively fixedly connected to the second bevel gear and the third bevel gear, and the second bevel gear and the first bevel gear mesh with each other.

[0016] Furthermore, the second rotating assembly includes a third rotating rod and a fourth bevel gear; the third rotating rod is rotatably mounted through the upper end of the riser, and the fourth bevel gear is fixedly connected to the upper end of the third rotating rod. The fourth bevel gear and the third bevel gear mesh with each other, and the lower end of the third rotating rod is fixedly connected to the upper end of the turntable.

[0017] Furthermore, a second fixing cylinder is fixedly connected to the upper part of the side wall of the riser, and the upper end of the second fixing cylinder is open.

[0018] Furthermore, the reverse pumping mechanism includes a second valve body installed on the water supply pipe, one end of the water supply pipe is fixedly connected to the pumping pipe, the other end of the pumping pipe is fixedly connected to the inlet of the centrifugal pump, and a third valve body is installed on the pumping pipe.

[0019] The beneficial effects of this utility model are:

[0020] 1. When the fertilizer and water mixture flows in the inlet pipe, the water flow drives the centrifugal wheel to rotate. The centrifugal wheel drives the first bevel gear to rotate through the first rotating rod. The first bevel gear meshes with the second bevel gear, causing the second rotating rod to rotate. The third bevel gear at the other end of the second rotating rod meshes with the fourth bevel gear, thereby driving the third rotating rod to rotate. The turntable fixed to the lower end of the third rotating rod rotates accordingly. The bristles at the lower end of the turntable continuously wipe the bottom surface of the inner wall of the nozzle, scraping off the undissolved fertilizer adhering to the bottom surface of the inner wall of the nozzle, effectively preventing nozzle blockage and ensuring the smooth progress of the fertilization process.

[0021] 2. This solution also provides another anti-clogging method. By closing the first and second valve bodies and opening the third valve body, the centrifugal pump is turned on to draw out the water in the connecting pipe. This will discharge the water remaining in the mixing drum, the first annular pipe, the water supply pipe and the riser through the centrifugal pump, forming a reverse water flow. This will cause the first rotating rod to rotate in the opposite direction, and the bristles will rotate in the opposite direction. In addition, the reverse water flow can generate negative pressure. Combined with the positive pressure generated by the water pump, the nozzle orifice will be subjected to an upward suction force. In this way, if there are particles blocking the orifice, under the action of the forces in both directions, the blockage will be dislodged from the orifice more quickly.

[0022] 3. During the flow of the mixed liquid, the centrifugal wheel rotates inside the carrier box, using centrifugal force to accelerate the centrifugal mixing of fertilizer and water. The high-speed rotation of the centrifugal wheel generates a strong vortex in the mixed liquid inside the carrier box, further breaking down and dispersing undissolved fertilizer particles, accelerating their dissolution process, significantly improving the uniformity and efficiency of fertilizer-water mixing, and providing crops with a higher quality fertilizer solution;

[0023] 4. The lower end of the second annular pipe in the fertilization assembly has evenly distributed water outlet holes. The fertilizer solution in the first annular pipe flows into the second annular pipe through the second support rod and then flows out from the water outlet holes. Because the second annular pipe is located at a lower position, the fertilizer solution can directly penetrate into the deep soil. Compared with traditional fertilization pipes, it can more effectively deliver fertilizer to the deep root system of crops, meet the nutritional needs of deep roots, promote the healthy growth and development of crop roots, and improve the overall growth quality and yield of crops.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1: Please refer to Figures 1-8 The ring-shaped distributed fertilization pipeline device includes a water supply component 1, multiple outlet ends of the water supply component 1 are respectively fixed to the inlet ends of multiple connecting pipes 2, the outlet ends of the connecting pipes 2 are connected to a carrier box 3, and a stirring drum 4 is fixed to the upper end of the carrier box 3.

[0035] The water outlet of the carrier box 3 is connected to one end of the water inlet pipe 8, and the other end of the water inlet pipe 8 is connected to the first annular pipe 9. The lower end of the first annular pipe 9 is provided with a fertilizer component. One end of the water supply pipe 10 is connected to the first annular pipe 9, and the other end of the water supply pipe 10 is connected to the riser pipe 11. The lower end of the riser pipe 11 is fixedly connected to the nozzle 13.

[0036] The nozzle 13 is a hollow disc-shaped structure, and the interior of the nozzle 13 is interconnected with the interior of the riser pipe 11. Multiple water spray holes are opened through the lower end of the nozzle 13.

[0037] A first rotating assembly 5 is rotatably mounted on the mixing drum 4, a linkage assembly 6 is mounted on the water inlet pipe 8, and a second rotating assembly 7 is rotatably mounted on the riser pipe 11. The power output end of the first rotating assembly 5 meshes with the power input end of the linkage assembly 6, and the power output end of the linkage assembly 6 meshes with the power input end of the second rotating assembly 7. A centrifugal wheel 53 is fixedly connected to the power input end of the first rotating assembly 5. The centrifugal wheel 53 is located inside the bearing box 3. A turntable 73 is fixedly connected to the power output end of the third rotating rod 71. A brush bristle 74 is fixedly connected to the lower end of the turntable 73. The lower end of the brush bristle 74 is in contact with the bottom surface of the inner wall of the nozzle 13.

[0038] When the second rotating component 7 rotates, the turntable 73 rotates, causing the bristles 74 to wipe the bottom surface of the inner wall of the nozzle 13.

[0039] The water supply component 1 is also equipped with a reverse pumping mechanism for pumping water from the connecting pipe 2.

[0040] In use, the water supply component 1 supplies water to the connecting pipe 2. The water flow drives the first rotating component 5 to rotate, the first rotating component 5 drives the linkage component 6 to rotate, the linkage component 6 drives the second rotating component 7 to rotate, and the second rotating component 7 drives the turntable 73 to rotate, which can wipe the bottom surface of the inner wall of the nozzle 13 to prevent the water spray hole at the lower end of the nozzle 13 from being blocked. In addition, the centrifugal wheel 53 at the lower end of the first rotating component 5 can accelerate the mixing of fertilizer and water. When the reverse pumping mechanism is activated, the water in the nozzle 13 can be pumped out. At this time, large particles of impurities blocked in the nozzle 13 can be pumped out in the reverse direction through the reverse pumping mechanism.

[0041] Please see Figure 1 and Figure 8 In this embodiment, the water supply component 1 includes a water tank 101, a water pump 102, a water delivery pipe 103, and a first valve body 104. The inlet end of the connecting pipe 2 is connected to the water delivery pipe 103, the water delivery pipe 103 is provided with the first valve body 104, the inlet end of the water delivery pipe 103 is connected to the outlet end of the water pump 102, and the pumping end of the water pump 102 is connected to the outlet end of the water tank 101 through a pipe. By setting up the water tank 101, water source storage can be provided, and the water pump 102 ensures the water flow power and facilitates water supply.

[0042] Please see Figure 1 and Figure 4 In this embodiment, there is a gap between the side wall of the third rotating rod 71 and the inner wall of the riser 11. This design ensures that the third rotating rod 71 can rotate freely, avoids friction with the inner wall of the riser 11 that hinders its rotation, ensures that the second rotating assembly 7 can operate smoothly, and thus enables the turntable 73 and the brush bristles 74 to work normally, preventing the nozzle 13 from becoming clogged.

[0043] Please see Figures 4-6In this embodiment, the first rotating assembly 5 includes a first rotating rod 51 and a first bevel gear 52; the first rotating rod 51 is rotatably mounted through the upper end of the mixing drum 4, the first bevel gear 52 is fixedly connected to the upper end of the first rotating rod 51, and the centrifugal wheel 53 is fixedly connected to the lower end of the first rotating rod 51. The structure of the first rotating assembly 5 is clearly defined. The first rotating rod 51 serves as a transmission hub, connecting the centrifugal wheel 53 and the first bevel gear 52, so that the power generated by the centrifugal wheel 53 when rotating in the bearing box 3 can be transmitted through the first bevel gear 52 to drive the subsequent linkage assembly 6 and the second rotating assembly 7 to work, thereby realizing the centrifugal mixing of fertilizer and water and the cleaning of the inner wall of the nozzle 13.

[0044] Please see Figures 4-6 In this embodiment, the linkage component 6 includes a first support rod 61, a first fixed cylinder 62, a second rotating rod 63, and a second bevel gear 64. The upper end of the water inlet pipe 8 is fixedly connected to the first support rod 61, and the upper end of the first support rod 61 is fixedly connected to the first fixed cylinder 62. The inner wall of the first fixed cylinder 62 is rotatably mounted with the second rotating rod 63. The two ends of the second rotating rod 63 are respectively fixedly connected to the second bevel gear 64 and the third bevel gear 65. The second bevel gear 64 and the first bevel gear 62 mesh with each other. The bevel gears at both ends of the second rotating rod 63 can effectively transmit power and change direction by meshing with the bevel gears of the first rotating component 5 and the second rotating component 7.

[0045] Please see Figure 4 , Figure 6 and Figure 7 In this embodiment, the second rotating assembly 7 includes a third rotating rod 71 and a fourth bevel gear 72. The third rotating rod 71 is rotatably mounted through the upper end of the riser 11. The fourth bevel gear 72 is fixedly connected to the upper end of the third rotating rod 71. The fourth bevel gear 72 and the third bevel gear 65 mesh with each other. The lower end of the third rotating rod 71 is fixedly connected to the upper end of the turntable 73. The third rotating rod 71 transmits the power transmitted by the linkage assembly 6 to the turntable 73. The meshing of the fourth bevel gear 72 and the third bevel gear 65 ensures the accuracy and stability of the power transmission, ensuring that the turntable 73 and the brush bristles 74 can rotate stably and continuously wipe the bottom surface of the inner wall of the nozzle 13, effectively preventing the nozzle 13 from clogging.

[0046] Please see Figure 1 and Figure 4 In this embodiment, a second fixing cylinder 12 is fixedly connected to the upper part of the side wall of the riser 11. The upper end of the second fixing cylinder 12 is open. The setting of the second fixing cylinder 12 can provide additional protection for the riser 11.

[0047] Example 2: Please refer to Figure 3Based on Embodiment 1, this application provides a technical solution: the fertilization component includes a second support rod 14 and a second annular tube 15; a plurality of second support rods 14 are fixedly connected to the side wall of the first annular tube 9, and the lower ends of the plurality of second support rods 14 are jointly fixedly connected to the second annular tube 15. Both the second support rods 14 and the second annular tube 15 are hollow structures, and the interiors of the second support rods 14 and the second annular tube 15 are interconnected. The lower end of the second annular tube 15 is provided with uniformly distributed water outlet holes 16. Through the fertilization component composed of the second support rods 14 and the second annular tube 15, the fertilizer solution in the first annular tube 9 can be transported downward to the deep soil. The hollow structure and interconnected design ensure smooth flow of the fertilizer solution, and the uniformly distributed water outlet holes 16 enable the fertilizer solution to penetrate evenly into the deep soil, thereby enhancing the fertilization capacity of the deep soil roots.

[0048] Please see Figure 1 and Figure 8 The reverse pumping mechanism includes a second valve body 105 disposed on the water supply pipe 103, one end of the pumping pipe 17 is fixedly connected to the water supply pipe 103, the other end of the pumping pipe 17 is fixedly connected to the inlet end of the centrifugal pump 18, and a third valve body 19 is disposed on the pumping pipe 17.

[0049] Close the first valve body 104 and the second valve body 105, open the third valve body 19, and start the centrifugal pump 18 to draw out the water in the connecting pipe 2. The water remaining in the mixing drum 4, the first annular pipe 9, the water supply pipe 10 and the riser pipe 11 will be discharged outward by the centrifugal pump 18, forming a reverse water flow. This will cause the first rotating rod 51 to rotate in the opposite direction, and the bristles 74 will rotate in the opposite direction. In addition, the reverse water flow can generate negative pressure. Combined with the positive pressure generated by the water pump 102, the orifice of the nozzle 13 will be subjected to an upward suction force. In this way, if there are particles blocking the orifice, under the action of the forces in both directions, the blockage will be more quickly dislodged from the orifice.

[0050] Working principle: When in use, the water tank 101 stores water. The water tank 101 can be connected to an external pipe to supply fertilizer water, keeping the water tank 101 always full of water. Then, after the water pump 102 starts, it draws out the water from the water tank 101 and delivers it to the carrier box 3 through the water delivery pipe 103 and the connecting pipe 2.

[0051] After water enters the carrier box 3, it drives the centrifugal wheel 53 of the first rotating component 5 to rotate. When the centrifugal wheel 53 rotates, it uses centrifugal force to accelerate the mixing of fertilizer and water in the carrier box 3.

[0052] Meanwhile, the centrifugal wheel 53 drives the first bevel gear 52 to rotate via the first rotating rod 51. The first bevel gear 52 meshes with the second bevel gear 64 of the linkage assembly 6, causing the second rotating rod 63 to rotate. The third bevel gear 65 on the second rotating rod 63 rotates accordingly. The third bevel gear 65 meshes with the fourth bevel gear 72 of the second rotating assembly 7, driving the third rotating rod 71 to rotate. The turntable 73 fixed to the lower end of the third rotating rod 71 also rotates accordingly. The bristles 74 at the lower end of the turntable 73 wipe the bottom surface of the inner wall of the nozzle 13 to prevent the water spray holes at the lower end of the nozzle 13 from being blocked by undissolved fertilizer.

[0053] The mixed fertilizer solution flows from the carrier box 3 into the first annular pipe 9 through the water inlet pipe 8, and a portion of the fertilizer solution is sprayed out from the spray hole of the nozzle 13 through the water supply pipe 10 and the riser pipe 11.

[0054] Another portion of the fertilizer solution flows into the second annular pipe 15 through the second support rod 14 on the side wall of the first annular pipe 9, and then flows out from the water outlet holes 16 evenly distributed at the lower end of the second annular pipe 15, penetrating into the deep soil to provide fertilizer for the deep roots of the crop.

[0055] Furthermore, by closing the first valve body 104 and the second valve body 105 and opening the third valve body 19, the centrifugal pump 18 is activated to extract the water flow in the connecting pipe 2. The water remaining in the mixing drum 4, the first annular pipe 9, the water supply pipe 10, and the riser pipe 11 is discharged outward through the centrifugal pump 18, forming a reverse water flow. This causes the first rotating rod 51 to rotate in the opposite direction, and the bristles 74 to rotate in the opposite direction. In addition, the reverse water flow can generate negative pressure, which, combined with the positive pressure generated by the water pump 102, causes the nozzle 13 to be subjected to an upward suction force. Thus, if there are particles blocking the holes, under the action of the forces in both directions, the blockage will be dislodged from the holes more quickly.
