Description

Technical Field

[0001] This invention relates to the field of potato seedling cultivation technology, specifically to a water-saving drip irrigation device for potato seedling cuttings. Background Technology

[0002] Potato cuttings are a core step in the efficient propagation of potatoes. They are sensitive to water and require precise control. Traditional flood irrigation methods have problems such as low water utilization (only 40%-50%), soil compaction, and uneven moisture during the seedling stage, which can easily lead to root rot or delayed seedling establishment.

[0003] In related technologies, to enable drip irrigation and recycling of nutrient solution in potato seedling cultivation, for example, patent CN216722293U provides a tidal drip irrigation potato seedling cultivation device. When the nutrient solution drip irrigation capacity needs adjustment, the pump is activated via a switch group. The pump's inlet pipe draws nutrient solution from the storage tank and delivers it through the output pipe to the first connecting pipe. The first connecting pipe then delivers it through a connecting box to the second connecting pipe, which in turn delivers it to an annular spray nozzle for drip irrigation of the seedlings. An electric telescopic rod drives a moving block to slide on a round rod and presses against an inclined rod. The inclined rod causes a trapezoidal block to contact the adjusting groove, and the trapezoidal block causes a slider to slide on a positioning rod, thus allowing for controlled drip irrigation of the nutrient solution according to the seedlings' different ages. Furthermore, the nutrient solution flows through the seedbed into the third connecting pipe, where it is filtered through a filter box in a fixed box, trapping debris. The nutrient solution then flows through a fourth connecting pipe into the storage tank, achieving a recycling effect.

[0004] Although the existing technical solutions mentioned above achieve the effects of drip irrigation and recycling of nutrient solution by setting up nozzles and using components, the nutrient solution needs to be filtered during the recycling process to prevent clogging of the nozzles. The filter box needs to be cleaned or replaced after a certain period of use. If cleaning and replacement are not done in time, the nutrient solution cannot be used in time and is prone to deterioration and waste over a long period of time, making the recycling of nutrient solution quite troublesome. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water-saving drip irrigation device for potato seedling cuttings, which can effectively solve the problem of the cumbersome recycling of nutrient solution in the existing technology.

[0018] A drive disc is fixedly installed on the inner side of the first tube shell. A first guide rail, a second guide rail, and an equal-diameter guide rail are provided on the outer side of the drive disc in conjunction with rollers. The first guide rail, the second guide rail, and the equal-diameter guide rail are connected end to end in sequence. The first guide rail and the second guide rail are used to drive the piston to slide to the outside and inside of the liquid storage tube, respectively.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] The present invention will be further described below with reference to embodiments.

[0044] Please see Figures 1-8 This invention provides a technical solution: a water-saving drip irrigation device for potato seedling cuttings, comprising a cutting bed 1, water pipes 2, and drip irrigation pipes 3. The top of the cutting bed 1 is evenly provided with planting troughs 11 for cutting potato seedlings; several water pipes 2 are provided corresponding to each row of planting troughs 11, and the water pipes 2 are driven to rotate synchronously by external force; the drip irrigation pipes 3 are evenly arranged on the outside of the water pipes 2 corresponding to each planting trough 11, the drip irrigation pipes 3 are fixedly connected to the water pipes 2, and are vertically offset from the planting troughs 11. The drip irrigation action is automatically triggered when the output end of the drip irrigation pipe 3 faces upwards towards the planting trough 11; wherein, a medicine tank 12 is fixedly provided at the bottom of the cutting bed 1, and a filter plate 13 for filtering nutrient solution is provided between the cutting bed 1 and the medicine tank 12, with one side of the filter plate 13 tilted downwards; a medicine pump 17 is fixedly provided on the outside of the medicine tank 12 for inputting the nutrient solution inside the medicine tank 12 into the water pipes 2. Specifically, an observation window 15 and a dosing tube 16 are fixedly installed on the outside of the medicine box 12 above the filter plate 13, and a display and control device 111 is also fixedly installed on the outside of the medicine box 12.

[0045] After the potato seedlings are planted, the nutrient solution inside the medicine tank 12 is pumped into each water pipe 2 by the medicine pump 17. The solution is then distributed to each drip irrigation pipe 3. At this point, the drip irrigation pipe 3 is positioned above the planting trough 11. This staggered arrangement reduces the obstruction of the space above the seedlings by the water pipes 2 and drip irrigation pipes 3, ensuring the seedlings receive sufficient sunlight. When drip irrigation is needed, external force drives the water pipes 2 to rotate, causing the output end of the drip irrigation pipe 3 to rotate upwards towards the planting trough 11. When the drip irrigation position of the drip irrigation pipe 3 is within the area of ​​the planting trough 11, the drip irrigation pipe 3 automatically contacts the water pipe. The drip irrigation system delivers nutrient solution into the planting trough 11, allowing the potato seedlings inside to grow. After the nutrient solution penetrates the growing medium inside the planting trough 11, it drips down through the porous structure at the bottom of the trough 11. The nutrient solution that drips onto the top of the filter plate 13 is initially filtered to remove impurities before returning to the medicine tank 12 for reuse. Because the filter plate 13 is inclined inside the medicine tank 12, it filters the nutrient solution over a large area. Furthermore, the nutrient solution flows downwards along the inclined surface, which helps disperse impurities, prevents accumulation and blockage, and extends the service life, eliminating the need for frequent replacements.

[0046] It also includes a mixing component 4, which includes a stirring shaft 41 rotatably disposed inside the medicine box 12. A perforated plate 42 is fixedly disposed on the outside of the stirring shaft 41. The stirring shaft 41 is driven by a motor B43 to trigger a stirring action. The motor B43 is fixedly disposed on the outside of the medicine box 12. The bottom of the medicine box 12 is provided with an arc-shaped surface 113.

[0047] Before cultivating potato seedlings, the stirring shaft 41 is driven by motor B43 to rotate inside the medicine box 12. The stirring shaft 41 drives the perforated plate 42 to stir the nutrient solution raw materials inside the medicine box 12, so as to quickly prepare the nutrient solution. The arc-shaped surface 113 at the bottom of the medicine box 12 can prevent the nutrient solution raw materials from accumulating in the stirring dead corners and affecting the mixing effect.

[0048] To facilitate the disassembly and installation of the filter plate 13 and subsequent maintenance, a filter frame 131 is fixedly installed on the outer side of the filter plate 13. An arc-shaped plate 132 is fixedly installed on the side of the filter frame 131 located outside the medicine box 12. The arc-shaped plate 132 fits against the outer side of the medicine box 12. A retaining plate 133 is fixedly installed on the bottom side of the filter frame 131 that fits against the inner wall of the medicine box 12. The retaining plate 133 is located on the side close to the arc-shaped plate 132. A support frame 112 is fixedly installed on the inner side of the medicine box 12 at an angle corresponding to the filter frame 131. The side of the support frame 112 close to the arc-shaped plate 132 is inclined downward.

[0049] When disassembling the filter plate 13, lift the arc plate 132 upwards to slide it against the outside of the medicine box 12, thereby lifting the retaining plate 133 at the bottom of the filter frame 131, and then pull the filter frame 131 horizontally to move the filter plate 13 out. Similarly, during installation, lift the arc plate 132 against the outside of the medicine box 12 upwards and then lower it to lock the retaining plate 133 inside the medicine box 12, ensuring the stability of the filter plate 13 installation and guiding the nutrient solution filtered by the filter plate 13 into the interior of the medicine box 12 to prevent nutrient solution leakage.

[0050] To enable the drip irrigation pipe 3 to trigger the drip irrigation action, the water pipe 2 includes a first pipe shell 21. Both ends of the inner side of the first pipe shell 21 are fixedly provided with end caps 22. A second pipe shell 23 is sealed and fixedly provided on the outer side of the first pipe shell 21 and the end caps 22. The drip irrigation pipe 3 is arranged and fixedly provided on the outer side of the first pipe shell 21. The drip irrigation pipe 3 is connected to a liquid storage pipe 31 fixedly provided on the outer side of the first pipe shell 21. A drip irrigation cap 32 is fixedly provided at the output end of the liquid storage pipe 31. A piston 33 is slidably provided on the inner side of the liquid storage pipe 31. The piston 33 is driven by the water pipe 2 to slide back and forth inside and outside the liquid storage pipe 31. The diameter of the output end of the drip irrigation cap 32 is larger than the filtration diameter of the filter plate 13.

[0051] When the water pipe 2 rotates, it drives the piston 33 to move from the outside to the inside of the storage pipe 31, pressurizing the nutrient solution inside the storage pipe 31. The piston 33 slides a consistent distance each time, making the amount of drip irrigation more uniform. After each drip irrigation, as the water pipe 2 continues to rotate, the piston 33 will automatically move to the outside of the storage pipe 31 when the output end of the storage pipe 31 is facing down. At this time, the nutrient solution inside the water pipe 2 will automatically flow into the storage pipe 31 for temporary storage. The nutrient solution inside the storage pipe 31 will not flow out through the drip irrigation tube 32 due to liquid surface tension (i.e., surface tension is greater than gravity). When the output end of the drip irrigation tube 32 faces the planting trough 11 again, the next drip irrigation will begin, thus achieving the effect of continuous drip irrigation. Specifically, a push rod 34 is fixedly installed on the side of the drip irrigation pipe 3 away from the liquid storage pipe 31. A perforated disk 28 is slidably installed on the outside of the push rod 34. The perforated disk 28 is fixedly installed inside the first pipe shell 21. A roller 35 is rotatably installed on the other end of the push rod 34. A drive disk 24 is fixedly installed inside the first pipe shell 21. A first guide rail 241, a second guide rail 242, and a constant diameter guide rail 243 are provided on the outside of the drive disk 24 in conjunction with the roller 35. The first guide rail 241, the second guide rail 242, and the constant diameter guide rail 243 are connected end to end in sequence. The first guide rail 241 and the second guide rail 242 are used to drive the piston 33 to slide to the outside and inside of the liquid storage pipe 31, respectively.

[0052] As the water pipe 2 rotates, it drives the roller 35 to roll along the first guide rail 241, the second guide rail 242, and the equal-diameter guide rail 243. During this movement, when the water pipe 2 and the drip irrigation pipe 3 are in a vertical position, the roller 35 is located at the connection between the first guide rail 241 and the second guide rail 242. At this time, the roller 35 pushes the piston 33 through the push rod 34 to seal the top of the storage pipe 31. This is a suitable time to add nutrient solution into the water pipe 2. As the roller 35 moves inside the second guide rail 242, it gradually pushes the piston 33 to slide into the storage pipe 31. The water pipe 2 rotates, causing the nutrient solution inside the storage pipe 31 to be pressurized and dripped into the corresponding planting trough 11. As the water pipe 2 continues to rotate, the roller 35 moves inside the equal diameter guide rail 243. At this time, the piston 33 and the storage pipe 31 remain relatively stationary. When the roller 35 begins to pass the first guide rail 241, it will drive the piston 33 to move out of the storage pipe 31. At this time, the output end of the storage pipe 31 tilts downward, allowing the nutrient solution inside the water pipe 2 to enter the storage pipe 31 by itself. This process is repeated to achieve the effect of automatically triggering a drip irrigation action every time the water pipe 2 rotates once.

[0053] In the above technical solution, the piston 33 is driven by the water pipe 2 to slide back and forth inside the liquid storage pipe 31, and the sliding distance of multiple pistons 33 remains relatively consistent, making the amount of drip irrigation more uniform each time. Compared with the method of setting an electric control valve, it reduces the energy consumption of the device, simplifies the complexity of the system, and improves the reliability of implementation.

[0054] More importantly, the nutrient solution may contain some fine particles or flocculent matter. When using an electronically controlled valve, these particles or flocculent matter can easily clog the valve core, causing poor drip irrigation. However, the piston 33 in this technical solution can apply a certain pressure to the nutrient solution inside the storage pipe 31, pushing the nutrient solution in the storage pipe 31 to drip into the planting trough 11. When there are fine particles or flocculent matter in the nutrient solution, the piston 33 can prevent the fine particles and flocculent matter from causing blockage in the storage pipe 31 and the water pipe 2, so that the nutrient solution can flow smoothly through the storage pipe 31 for drip irrigation, ensuring the drip irrigation effect.

[0055] In addition, in the above technical solutions, the triggering of the drip irrigation action of multiple drip irrigation pipes 3 depends only on the rotation of water pipe 2; if an electric control valve is used, the opening and closing time of multiple electric control valves needs to be strictly controlled, which requires a precise control system and increases production costs; if the opening and closing of multiple solenoid valves are not synchronized, it may lead to uneven drip irrigation of multiple potato seedlings.

[0056] A rod frame 27 is fixedly installed inside the first tube shell 21. A fixing rod 25 is fixedly installed inside the rod frame 27. A drive disc 24 is fixedly installed outside the fixing rod 25. A needle rod 26 is fixedly installed between two adjacent liquid storage tubes 31 outside the fixing rod 25.

[0057] When the water pipe 2 rotates, it will agitate the nutrient solution inside. In conjunction with the needle rod 26 inside the water pipe 2, it can improve the disturbance effect on the nutrient solution and prevent small impurities from accumulating inside the water pipe 2, which would affect the capacity of the water pipe 2 and the drip irrigation effect.

[0058] A liquid supply sealing cylinder 211 is fixedly installed at one end of the fixed rod 25. A rotating sealing ring 29 is slidably installed on the inner side of the liquid supply sealing cylinder 211. The rotating sealing ring 29 is fixedly installed on the outer side of the end cap 22 at one end. A shaft frame 210 for supporting the fixed rod 25 is fixedly installed on the inner side of the rotating sealing ring 29. The liquid supply sealing cylinder 211 is fixedly installed to the side plate 14 on the top of the cutting bed 1 through a flange 213. The end cap 22 at the other end is rotatably connected to the side plate 14 on the top of the cutting bed 1. Specifically, a sprocket 214 is fixedly installed on the outer side of the end cap 22. The sprockets 214 are synchronously linked through a chain 215. One of the sprockets 214 rotates under the drive of a motor A216. The motor A216 is fixedly installed on the outer side of the medicine box 12.

[0059] During drip irrigation, motor A216 drives one of the sprockets 214 to rotate, which in turn drives the other sprockets 214 to rotate synchronously via chain 215. This causes the sprockets 214 to drive the water pipe 2 to rotate synchronously, thus ensuring the consistency of drip irrigation. At this time, the nutrient solution output from the liquid supply sealing cylinder 211 enters the interior of the water pipe 2 through the inner side of the rotating sealing ring 29, so that the water pipe 2 can be continuously replenished with nutrient solution during rotation. Furthermore, the rotation speed of the water pipe 2 can be adjusted by adjusting the driving speed of motor A216, so as to control the drip irrigation efficiency of the drip irrigation pipe 3.

[0060] A diversion pipe 19 is fixedly installed on the top of the cutting bed 1. The diversion pipe 19 is fixedly connected to the outlet pipe 18 of the output end of the medicine pump 17. A solenoid valve 110 is fixedly installed on several supply sealing cylinders 211 corresponding to the output end of the diversion pipe 19. The output end of each solenoid valve 110 is fixedly connected to the supply sealing cylinder 211 through a connecting pipe 212. Since the dripping volume of the drip irrigation pipe 3 is constant, and the dripping efficiency of the drip irrigation pipe 3 can be controlled by adjusting the rotation speed of the water pipe 2, the total dripping volume of the drip irrigation pipe 3 within a specified time can be calculated. Then, the display controller 111 controls the opening and closing of the solenoid valve 110 according to the total dripping volume of the drip irrigation pipe 3, so that the medicine pump 17 intermittently replenishes the nutrient solution into the supply sealing cylinder 211 to ensure the continuity of drip irrigation and facilitate precise control of the dripping volume to achieve water-saving effect.

[0061] The principle and advantages of water-saving drip irrigation devices for potato seedling cuttings:

[0062] First, the stirring shaft 41 is driven by motor B43 to rotate inside the medicine tank 12, causing the stirring shaft 41 to drive the perforated plate 42 to stir the nutrient solution raw materials inside the medicine tank 12, so as to quickly prepare the nutrient solution. After the potato seedlings are inserted into the planting trough 11, the nutrient solution inside the medicine tank 12 is input into each water pipe 2 by the medicine pump 17, and then distributed to each drip irrigation pipe 3 through the water pipe 2. At this time, the drip irrigation pipe 3 is located on one side above the planting trough 11. The staggered arrangement reduces the obstruction of the space above the potato seedlings by the water pipe 2 and the drip irrigation pipe 3, so as to ensure that the potato seedlings can receive sufficient sunlight. Then, when drip irrigation is needed, the water pipe 2 is driven by external force to rotate, so that the water pipe 2 drives the output end of the drip irrigation pipe 3 to rotate upwards towards the planting trough 11. When the drip irrigation position of the drip irrigation pipe 3 is within the range of the planting trough 11, the drip irrigation pipe 3 will automatically trigger the drip irrigation action to drip the nutrient solution inside into the planting trough. Inside the planting trough 11, the potato seedlings planted inside are cultivated. After the nutrient solution permeates the cultivation medium inside the planting trough 11, it drips down through the porous structure at the bottom of the planting trough 11. The nutrient solution dripping onto the top of the filter plate 13 is initially removed and then returned to the inside of the medicine tank 12 for reuse. When disassembling the filter plate 13, the arc plate 132 is lifted upwards and slid against the outside of the medicine tank 12, thereby lifting the retaining plate 133 at the bottom of the filter frame 131. Then, the filter frame 131 is pulled out horizontally, and the filter plate 13 is moved out. Similarly, during installation, the arc plate 132 is first lifted upwards against the outside of the medicine tank 12 and then lowered to make the retaining plate 133 lock into the inside of the medicine tank 12, so as to ensure the stability of the filter plate 13 installation and guide the nutrient solution filtered by the filter plate 13 into the inside of the medicine tank 12, preventing nutrient solution leakage.

[0063] Its advantages include: the nutrient solution is filtered by the inclined filter plate 13, which increases the filtration area and the nutrient solution will tilt downwards along the inclined surface, which helps to disperse impurities and prevent accumulation and blockage, thus increasing the effective filtration time and eliminating the need for frequent replacement; and the staggered setting reduces the obstruction of the space above the potato seedlings by the water pipe 2 and the drip irrigation pipe 3, ensuring that the potato seedlings can receive sufficient sunlight. When drip irrigation is needed, the water pipe 2 will drive the drip irrigation pipe 3 to rotate upwards towards the planting trough 11 and automatically trigger the drip irrigation action.

[0064] In the drip irrigation device for potato seedling cutting propagation of this application, the water pipe 2 and drip irrigation pipe 3 are driven by motor A216 to rotate one of the sprockets 214, which drives the other sprockets 214 to rotate synchronously through chain 215. The sprockets 214 drive the water pipe 2 to rotate synchronously. When the water pipe 2 rotates, it drives the roller 35 to roll along the first guide rail 241, the second guide rail 242 and the equal diameter guide rail 243. During the movement, when the water pipe 2 drives the drip irrigation pipe 3 to be in a vertical state, the roller 35 is located at the connection of the first guide rail 241 and the second guide rail 242. At this time, the roller 35 pushes the piston 33 through the push rod 34 to seal the top of the liquid storage pipe 31. At this time, it is suitable to add nutrient solution into the water pipe 2.

[0065] When the roller 35 moves inside the second guide rail 242, it will gradually push the piston 33 to slide into the inside of the liquid storage tube 31, so that the nutrient solution inside the liquid storage tube 31 is pressured and dripped into the corresponding planting trough 11. When the water pipe 2 continues to rotate, the roller 35 will move inside the equal diameter guide rail 243. At this time, the piston 33 and the liquid storage tube 31 remain relatively stationary.

[0066] When the roller 35 begins to pass the first guide rail 241, it will drive the piston 33 to move out of the inside of the storage tube 31. At this time, the output end of the storage tube 31 is tilted downward, allowing the nutrient solution inside the water pipe 2 to enter the storage tube 31 by itself. At this time, the nutrient solution inside the water pipe 2 automatically flows into the storage tube 31 for temporary storage. The nutrient solution inside the storage tube 31 will not flow out by itself through the drip irrigation tube 32 due to the liquid tension. When the output end of the drip irrigation tube 32 faces the planting trough 11 again, the next drip irrigation will be carried out. At the same time, the water pipe 2 will drive the nutrient solution inside to stir together. With the needle rod 26 inside the water pipe 2, the disturbance effect of the nutrient solution can be improved, preventing small impurities from accumulating inside the water pipe 2 and affecting the capacity of the water pipe 2 and the drip irrigation effect.

[0067] It is worth noting that the above-mentioned drip irrigation method has the following advantages:

[0068] Firstly, by driving the water pipe 2, the output end of the drip irrigation pipe 3 is moved upwards towards the planting trough 11, ensuring that the drip irrigation pipe 3 drips the nutrient solution into the corresponding planting trough 11. Furthermore, during the rotation of the water pipe 2, the driving piston 33 slides a certain distance inside the liquid storage pipe 31 to automatically trigger the drip irrigation action, so as to accurately control the drip irrigation amount and achieve the effect of water-saving drip irrigation.

[0069] Secondly, by setting up water pipe 2 to drive drip irrigation pipe 3 to automatically trigger drip irrigation, water pipe 2 continues to rotate after drip irrigation pipe 3 completes a single drip irrigation. This can work with the internal needle rod 26 to agitate the remaining nutrient solution inside, preventing fine impurities mixed in the nutrient solution from accumulating inside water pipe 2, thus extending the service life of water pipe 2 and reducing the number of maintenance times.

[0070] Thirdly, the drip irrigation efficiency of the drip irrigation pipe 3 can be controlled by adjusting the rotation speed of the water pipe 2, so as to adjust the drip irrigation amount according to the potato seedling cultivation time, and the drip irrigation amount adjustment is more accurate.

[0071] Fourthly, by setting up a storage pipe 31 to temporarily store the nutrient solution inside the water pipe 2, and finally drip irrigation is carried out through the drip irrigation capillary 32, as long as the output diameter of the drip irrigation capillary 32 is greater than the filtration radius of the filter plate 13, smooth drip irrigation can be achieved, preventing blockage of the drip irrigation pipe 3, and reducing the filtration requirements of the filter plate 13 for impurities.

[0072] Fifthly, the drip irrigation action is triggered by the piston 33 sliding and pressurizing inside the storage tube 31. This not only makes it easier to control the drip irrigation volume, but also makes it easier to flush out impurities attached to the inside of the storage tube 31 and the drip irrigation tube 32. This prevents impurities from accumulating statically inside the storage tube 31 and the drip irrigation tube 32 and causing blockage, thereby improving service life and reducing maintenance time.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
