Description

Technical Field

[0001] This application relates to the field of drip irrigation technology, and more specifically, to a drip irrigation device for peanut cultivation. Background Technology

[0002] Drip irrigation 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 is the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation. It can also be combined with fertilization to increase fertilizer efficiency by more than double. It is suitable for irrigating fruit trees, vegetables, cash crops, and greenhouses. It can also be used for field crop irrigation in arid and water-scarce areas. Its disadvantage is that the drippers are prone to scaling and clogging, so the water source should be strictly filtered.

[0003] When drip irrigation is being used, it is sometimes necessary to combine it with fertilization. Sometimes there are undissolved solid particles or flocculent matter in the fertilizer solution. In drip irrigation equipment, because the diameter of the drip head is small, it is easy to get clogged. When the existing equipment is clogged, it is difficult to find out which drip head is clogged in time because there are many drip heads. As a result, the peanut plants cannot receive drip irrigation, which affects the growth of the peanut plants.

[0004] In view of this, we propose a drip irrigation device for peanut cultivation. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a drip irrigation device for peanut cultivation, which solves the technical problems of easy clogging of drippers and small drip irrigation coverage area mentioned in the background art.

[0007] 2. Technical Solution

[0008] This application provides a drip irrigation device for peanut cultivation, including a drip pipe, with a drip head installed below the drip pipe. A separation system is provided inside the drip head, and the separation system includes a separation unit, a self-driving mechanism, a dredging mechanism, and an alarm mechanism.

[0009] The dropper and the drip head are connected. The self-driving mechanism includes a rocker and a fixed seat. The fixed seat is installed at the bottom of the drip head, and the middle part of the rocker is rotatably connected to the fixed seat.

[0010] A conical plate is provided above the rocker arm, and a through hole is provided in the center of the conical plate. The separation unit is located on the through hole.

[0011] A liquid storage cylinder is provided above one end of the rocker, and a dredging mechanism is provided at the bottom of the rocker below the liquid storage cylinder. The dredging mechanism includes a rotating rod and a dredging block. The rotating rod is rotatably connected to the bottom of the rocker, and the end of the rotating rod away from the rocker is connected to the dredging block. A first liquid outlet is provided at the bottom of the dripper, and the dredging block is located inside the first liquid outlet.

[0012] The other end of the rocker is provided with a first spring. The end of the first spring away from the rocker is connected to a conical plate. An alarm mechanism is provided at the bottom of the rocker located below the first spring. An alarm is installed on the drip head. The alarm mechanism includes a moving rod. When the first filter screen is clogged, the self-driving mechanism drives the moving rod to move, and the moving rod presses the alarm to sound an alarm.

[0013] The bottom of the dripper is provided with a receiving cylinder, and a branch pipe is connected to the dripper above the conical plate. The other end of the branch pipe is connected to the receiving cylinder. When the first filter screen is blocked, the liquid in the dripper is introduced into the receiving cylinder through the branch pipe for drip irrigation.

[0014] By adopting the above technical solution, the self-driven mechanism drives the unblocking mechanism and the alarm mechanism to operate. The self-driven mechanism drives the rocker plate of the self-driven mechanism to rotate by continuously accumulating water in the storage tank. The rotating rod and unblocking block installed on the rocker plate move synchronously, thereby unblocking the impurities accumulated in the first storage port. When a blockage occurs, the liquid in the storage tank gradually moves, and the rotation of the rocker plate simultaneously drives the moving rod in the alarm mechanism to move, triggering the alarm.

[0015] As an optional solution to the technical solution of this application, the separation unit includes a filter element and a top cover. The filter element is installed in a through hole in a conical plate. A support plate is provided at the bottom of the conical plate. The filter element is placed on the support plate. The top cover is threaded onto the filter element. The top cover has multiple circumferentially distributed liquid inlet holes. A solid adsorbent is placed inside the filter element.

[0016] By adopting the above technical solution and the matching of the filter element cover, when the liquid enters the filter element through the liquid inlet hole of the cover, the adsorbent in the filter element adsorbs the flocculent impurities in the liquid, and then the solid particulate impurities are filtered again through the filter element, thereby achieving more thorough separation and purification of the liquid.

[0017] As an optional solution to the technical solution of this application, the tapered plate is connected to a plurality of telescopic rods, the telescopic rods are connected to the liquid storage cylinder through connecting rods, the unblocking mechanism further includes a positioning cylinder, the positioning cylinder is rotatably connected to the bottom of the rocker, a rotating rod is concentrically rotatably connected to the positioning cylinder, and a plurality of fan-shaped grooves are formed on the surface of the unblocking block.

[0018] By adopting the above technical solution, the unblocking block has multiple fan-shaped grooves on its surface to allow the liquid to pass through the first outlet better. However, during unblocking, there are gaps between the fan-shaped grooves and the blockage impurities, which prevents it from being unblocked effectively. By using the positioning cylinder and the rotating rod in combination, the rotating rod can rotate while descending, thus improving the unblocking effect.

[0019] As an optional solution to the technical solution of this application, the surface of the rotating rod is provided with a spiral groove, the inner cavity of the first liquid outlet is provided with a fixed cylinder, a plurality of fixed rods are fixedly connected to the inner wall of the first liquid outlet, the ends of the plurality of fixed rods that are close to each other are fixedly connected to the fixed cylinder, and a driving pin is provided on the fixed cylinder, the driving pin extending into the spiral groove.

[0020] By adopting the above technical solution, the spiral groove, fixed cylinder and drive pin on the surface of the rotating rod cooperate to drive the rotating rod to rotate circumferentially while the rotating rod is descending, because the drive pin is in the spiral groove, thereby driving the unblocking block to rotate and descend, and the unblocking block unblocks.

[0021] As an optional solution to the technical solution of this application, the alarm mechanism further includes a triangular frame, which is rotatably connected to the bottom of the rocker plate. One end of the moving rod is slidably connected to the triangular frame, and the other end of the moving rod extends to the outside of the receiving cylinder. A second spring is sleeved on the outer wall of the moving rod.

[0022] By adopting the above technical solution, when the self-driven mechanism moves the triangular frame through the rocker, the triangular frame moves the sliding rod connected to it. At this time, the second spring is compressed, and the sliding rod gradually contacts and presses the alarm until the alarm is triggered.

[0023] As an optional solution to the technical solution of this application, a fixed rail is provided on the inner wall of the receiving cylinder, and the triangular frame is slidably connected in the fixed rail.

[0024] By adopting the above technical solution, the fixed rail is used to limit the triangular frame, prevent the triangular frame from shifting, and thus prevent the sliding rod from being affected.

[0025] As an optional solution to the technical solution of this application, the bottom of the receiving cylinder is provided with a second liquid outlet, and the inside of the receiving cylinder is provided with a filter screen.

[0026] By adopting the above technical solution, when the dripper becomes clogged, the liquid gathers above the conical plate. At this time, the branch pipe introduces the liquid above the conical plate into the receiving cylinder. The liquid is filtered through the filter screen and finally flows out from the second liquid outlet.

[0027] As an optional solution to the technical solution of this application, a mounting base is fixedly connected to the outer wall of the dropper, and a mounting groove corresponding to the mounting base is opened on the outer wall of the dropper, and the dropper head is threadedly connected to the mounting base.

[0028] By adopting the above technical solution, the installation base and dripper are connected by threads, which facilitates the disassembly of the dripper, thereby allowing for the cleaning of the filter element inside the dripper and the replacement of the adsorbent.

[0029] As an optional solution to the technical solution of this application, a liquid distribution plate is provided below the first discharge port, and a conical column is provided at the center of the surface of the liquid distribution plate. The conical column is located directly below the first discharge port. The surface of the liquid distribution plate is provided with a plurality of circumferentially distributed discharge grooves. The liquid distribution plate is connected to the dripper by a long rod.

[0030] By adopting the above technical solution, the combination of the liquid distribution plate and the conical column allows the liquid to be diverted through the conical column and introduced into the liquid distribution plate. The multiple liquid outlet grooves on the liquid distribution plate evenly distribute the liquid around the peanut plants, thereby achieving uniform drip irrigation. This avoids the problem of traditional drip irrigation methods that only irrigate one location, resulting in uneven irrigation of the peanut plants and affecting their normal growth. In addition, traditional drip irrigation methods are also prone to causing soil compaction, which affects the growth of peanut plants.

[0031] This application provides an optional solution in which a cylinder is provided at the bottom of the liquid storage cylinder, the cylinder is connected to the liquid storage cylinder, and the liquid inlet speed of the liquid storage cylinder is greater than the liquid outlet speed.

[0032] By adopting the above technical solution, the cylindrical water outlet is set up. When the filter element is not clogged, the liquid inlet speed of the storage tank is greater than the liquid outlet speed, so the storage tank is always full. Therefore, the storage tank presses down on the rocker, and the unblocking block descends, thereby clearing impurities. When the filter element is clogged, the storage tank only discharges water and does not receive water. At this time, the first spring restores its elastic deformation, pushes the rocker to rotate, until it drives the triangular frame to move down and squeeze the moving rod. The moving rod moves and squeezes the alarm, thereby triggering an alarm and prompting the management personnel to check for filter element clogging.

[0033] 3. Beneficial effects

[0034] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0035] 1. The separation system consists of a separation unit, a self-driven mechanism, a clearing mechanism, and an alarm mechanism. It utilizes the dripping liquid itself to drive the self-driven mechanism, which in turn drives the clearing mechanism, continuously clearing the drippers and ensuring smooth drip irrigation. This effectively prevents drippers from becoming clogged due to dust or impurities accumulating at the outlet during inactivity. The self-driven mechanism activates the alarm mechanism, alerting management personnel to any blockages. This allows for timely cleaning of clogged drippers, solving the problem in existing technologies where it's difficult to promptly identify which dripper is clogged due to the large number of drippers.

[0036] 2. In addition, the combination of branch pipes, receiving cylinders and filter screens allows drip irrigation to continue even when blockages occur, preventing management personnel from being unable to reach the site in time to handle blockages and thus affecting peanut growth.

[0037] 3. The conical column and distribution plate are designed to collect the liquid from the dripper onto the distribution plate, and the multiple distribution grooves on the distribution plate will evenly distribute the liquid to all parts of the peanut plant, thereby achieving uniform drip irrigation for individual plants.

[0038] 4. The combination of branch pipes, receiving cylinders, and filter screens allows the liquid inside the dripper to be introduced into the receiving cylinder through the filter screen when the dripper becomes clogged. The filter screen in the receiving cylinder filters the liquid before it flows out to drip irrigate the peanut plants, thus avoiding drip irrigation of the peanut plants due to dripper clogging.

[0039] 5. The rotating rod, fixed cylinder, and drive pin are designed to allow the rotating rod to rotate and descend simultaneously under the drive of the self-driving mechanism. This pushes impurities out of the first outlet, reducing the risk of external impurities accumulating in the first outlet due to wind force when the dripper is not used for a long time. This, in turn, helps the dripper to dispense water evenly. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or a link; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] Reference Figures 1 to 11 This application provides a drip irrigation device for peanut planting, including a drip pipe 1, a drip head 2 installed below the drip pipe 1, the drip pipe 1 and the drip head 2 are connected, and a separation system is provided inside the drip head 2. The separation system includes a separation unit 9, a self-driving mechanism 3, a clearing mechanism 4 and an alarm mechanism 5.

[0056] Reference Figure 3 , Figure 4 as well as Figure 11The self-driving mechanism 3 includes a rocker arm 31 and a fixed base 32. The fixed base 32 is installed at the bottom of the dripper 2. The middle part of the rocker arm 31 is rotatably connected to the fixed base 32. A conical plate 6 is provided above the rocker arm 31. A through hole is opened in the center of the conical plate 6. The separation unit 9 is located on the through hole. The separation unit 9 includes a filter element 902 and a top cover 901. The filter element 902 is installed in the through hole on the conical plate 6. A support plate is provided at the bottom of the conical plate 6. The filter element 902 is placed on the support plate. The top cover 901 is threadedly connected to the filter element 902. The top cover 901 has multiple circumferentially distributed liquid inlet holes 903. The filter element 902 contains a solid adsorbent. When the liquid enters the dropper 2 from the dropper 1, it passes through the conical plate 6. Since the center of the conical plate 6 is low and the edges are high, the liquid gathers in the through hole in the center of the conical plate 6. Then the liquid is adsorbed by the adsorbent in the filter element 902, which adsorbs the flocculent matter in the liquid. Then the liquid is filtered by the filter element 902. The filter element 902 filters the solid particles inside the liquid. Finally, the liquid is discharged through the liquid storage cylinder 10.

[0057] Reference Figures 3 to 6 A liquid storage cylinder 10 is provided above one end of the rocker arm 31. A cylinder is provided at the bottom of the liquid storage cylinder 10. The cylinder and the liquid storage cylinder 10 are connected. The cylinder is used for water discharge from the liquid storage cylinder 10. The water discharge speed of the cylinder is less than the water inflow speed of the liquid storage cylinder 10. This ensures that the liquid storage cylinder can be filled with water. A dredging mechanism 4 is provided at the bottom of the rocker arm 31 below the liquid storage cylinder 10. The dredging mechanism 4 includes a rotating rod 42 and a dredging block 47. The rotating rod 42 is rotatably connected to the bottom of the rocker arm 31. The end of the rotating rod 42 away from the rocker arm 31 is connected to the dredging block 47. A first liquid outlet 15 is provided at the bottom of the dripper 2. The dredging block 47 is located inside the first liquid outlet 15. After the dripper has not been used for a long time, water droplets remain on the surface of the first liquid outlet 15. External dust and impurities are easily blown by the wind and adhere to the first liquid outlet, causing blockage. The dredging mechanism is used to solve the problem of blockage of the first liquid outlet.

[0058] Reference Figures 8 to 10 The other end of the rocker 31 is provided with a first spring 33. The end of the first spring 33 away from the rocker 31 is connected to the conical plate 6. The bottom of the rocker 31 located below the first spring 33 is provided with an alarm mechanism 5. An alarm 7 is installed on the drip head 2. The alarm mechanism 5 includes a moving rod 53. When the separation unit 9 is blocked, the self-driving mechanism 3 drives the moving rod 53 to move, and the moving rod 53 presses the alarm 7 to sound an alarm.

[0059] Reference Figures 3 to 7When the filter element 902 is not clogged, the inflow rate of the liquid storage tank 10 is greater than the outflow rate, so the liquid storage tank 10 is always full. In this case, the liquid storage tank 10 presses the rocker plate 31, and the rocker plate 31 drives the rotating rod 42 to descend. The unblocking block 47 connected to the rotating rod 42 unblocks the first liquid outlet 15. At the same time, the liquid from the filter element 902 continues to fall into the liquid storage tank 10 until it overflows. Meanwhile, due to the cooperation of the first spring 33, the rocker plate 31 vibrates, which in turn causes the unblocking block 47 to move back and forth, thus improving the unblocking effect.

[0060] Reference Figure 3 , Figure 8 , Figure 9 as well as Figure 10 When the filter element 902 is blocked, the liquid storage tank 10 will only discharge water instead of entering it. As the liquid inside the liquid storage tank 10 flows out, the first spring 33 gradually restores its elastic deformation until all the liquid inside the liquid storage tank 10 has flowed out. At this time, the first spring 33 drives the rocker plate 31 to rotate, and the rocker plate 31 further drives the moving rod 53 to press the alarm 7, thereby prompting the management personnel that the filter element 902 is blocked.

[0061] Reference Figures 7 to 10 The bottom of the dripper 2 is provided with a receiving cylinder 13. A branch pipe 14 is connected to the dripper 2 above the conical plate 6. The other end of the branch pipe 14 is connected to the receiving cylinder 13. When the filter element 902 is blocked, the liquid in the dripper 2 is introduced into the receiving cylinder 13 through the branch pipe 14 for drip irrigation. When the filter element 902 is blocked, the liquid gathers above the conical plate 6. As the amount of liquid gathered increases, the liquid is introduced into the receiving cylinder 13 through the branch pipe 14 and then discharged through the filter screen 17.

[0062] Reference Figure 4 and Figure 5 This application provides a drip irrigation device for peanut cultivation. A tapered plate 6 is connected to a plurality of telescopic rods 11. The telescopic rods 11 are connected to the liquid storage cylinder 10 through connecting rods 12. The telescopic rods 11 and connecting rods 12 are designed to keep the liquid storage cylinder 10 in contact with the rocker plate 31, thereby squeezing the rocker plate 31 to rotate it, which in turn drives the unblocking mechanism 4 to operate. The unblocking mechanism 4 also includes a positioning cylinder 41, which is rotatably connected to the bottom of the rocker plate 31. A rotating rod 42 is concentrically rotatably connected to the positioning cylinder 41. A plurality of fan-shaped grooves are opened on the surface of the unblocking block 47. The positioning cylinder 41 is rotatably connected to the rocker plate 31 to cooperate with the rotation of the rocker plate 31.

[0063] Reference Figure 5 and Figure 6This application provides a drip irrigation device for peanut planting. The surface of the rotating rod 42 is provided with a spiral groove 43. The inner cavity of the first liquid outlet 15 is provided with a fixed cylinder 44. Multiple fixed rods 46 are fixedly connected to the inner wall of the first liquid outlet 15. The ends of the multiple fixed rods 46 that are close to each other are fixedly connected to the fixed cylinder 44. A driving pin 45 is provided on the fixed cylinder 44, and the driving pin 45 extends into the spiral groove 43.

[0064] Reference Figure 4 , Figure 5 as well as Figure 6 When the liquid storage cylinder 10 gradually fills with liquid, it drives the rocker plate 31 to rotate. The rocker plate 31 further drives the positioning cylinder 41 and the rotating rod 42 to move. The unblocking block 47 on the rotating rod 42 moves synchronously, thereby unblocking the first liquid outlet 15. At the same time, as the rotating rod 42 descends, the driving pin 45 and the spiral groove 43 on the rotating rod 42 work together. Due to the special shape of the spiral groove 43, the rotating rod 42 rotates under the action of the driving pin 45, thus achieving a better unblocking effect.

[0065] Reference Figure 8 and Figure 10 This application provides a drip irrigation device for peanut cultivation. The alarm mechanism 5 also includes a triangular frame 51, which is rotatably connected to the bottom of the rocker arm 31. One end of the moving rod 53 is slidably connected to the triangular frame 51, and the other end of the moving rod 53 extends to the outside of the receiving cylinder 13. A second spring 54 is sleeved on the outer wall of the moving rod 53. When a blockage occurs, the liquid storage cylinder 10 only discharges water and does not receive water, so the weight of the liquid storage cylinder 10 gradually decreases. At this time, the first spring 33 gradually recovers its deformation, the rocker arm 31 rotates, thereby driving the triangular frame 51 to move. The triangular frame 51 further drives the moving rod 53 to move. As the moving rod 53 gradually squeezes the alarm 7, the alarm 7 finally sounds, thereby reminding the management personnel that the filter element 902 is blocked.

[0066] Reference Figure 10 This application provides a drip irrigation device for peanut planting. A fixed rail 52 is provided on the inner wall of the receiving cylinder 13. A triangular frame 51 is slidably connected in the fixed rail 52. The fixed rail 52 is used to limit the triangular frame 51 to prevent it from rotating when the rocker 31 rotates, thus preventing it from contacting the moving rod 53 and thus preventing the moving rod 53 from moving.

[0067] Reference Figure 7 and Figure 9 This application provides a drip irrigation device for peanut planting. The bottom of the receiving cylinder 13 is provided with a second liquid outlet 16. The inside of the receiving cylinder 13 is provided with a filter screen 17. The filter screen 17 is used to filter the liquid in the receiving cylinder 13 and then discharge it through the second liquid outlet 16.

[0068] Reference Figure 2 and Figure 11 This application provides a drip irrigation device for peanut cultivation. A mounting base 8 is fixedly connected to the outer wall of the drip tube 1. A mounting groove corresponding to the mounting base 8 is opened on the outer wall of the drip tube 1. The dripper 2 is threadedly connected to the mounting base 8. The mounting base 8 and the dripper 2 are designed to be disassembled. When the filter element 902 and adsorbent inside the dripper 2 need to be replaced, the dripper 2 can be disassembled, the filter element 902 can be cleaned, and then the adsorbent can be replaced.

[0069] Reference Figure 2 and Figure 3 This application provides a drip irrigation device for peanut cultivation. A distribution plate 19 is provided below the first liquid outlet 15. A conical column 18 is provided at the center of the surface of the distribution plate 19, and the conical column 18 is located directly below the first liquid outlet 15. The surface of the distribution plate 19 has multiple circumferentially distributed liquid outlet grooves 20. The distribution plate 19 is connected to the dripper 2 by a long rod. With the cooperation of the distribution plate 19 and the conical column 18, after the liquid is discharged from the first liquid outlet 15, it first passes through the conical column 18. The conical column 18 evenly disperses the liquid onto the distribution plate 19. The liquid outlet grooves 20 on the distribution plate 19 evenly disperse the liquid to various positions of the peanut plant. Therefore, compared with the traditional fixed-position single-point drip irrigation, the effect is better, and at the same time, it avoids the soil compaction caused by single-point drip irrigation.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
