Description

Technical Field

[0001] This invention relates to the technical field of Salvia miltiorrhiza cultivation, and in particular to a drip irrigation device under mulch for ecological Salvia miltiorrhiza cultivation. Background Technology

[0002] Salvia miltiorrhiza is a Chinese medicinal herb with high medicinal value. In order to reduce pests and diseases and increase the yield of Salvia miltiorrhiza, most plants choose to grow Salvia miltiorrhiza under film and irrigate it by drip irrigation, such as the water-saving drip irrigation device disclosed in the invention patent with announcement number CN106358990B and the drip irrigation device disclosed in the invention patent with announcement number CN107535316B.

[0003] However, during use, it was found that existing drip irrigation devices are inconvenient for disinfecting and sterilizing the soil before planting, and are inconvenient for rescuing Salvia miltiorrhiza during heavy rain or floods, resulting in reduced yields and, in severe cases, death of the plants. This leads to poor practicality. Therefore, there is an urgent need for a drip irrigation device under film for ecological planting of Salvia miltiorrhiza to improve the above problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a drip irrigation device for Salvia miltiorrhiza cultivation. Before planting, the drip irrigation mechanism heats the water to generate steam, which is then discharged into the soil for high-temperature sterilization. After planting, the drip irrigation mechanism, in conjunction with a moving mechanism, provides three-dimensional root drip irrigation to ensure the Salvia miltiorrhiza meets its water needs. Subsequently, in the event of heavy rain or flooding, a drainage mechanism continuously drains water from the soil, removing most of the moisture and providing aeration to the roots, reducing root rot. This improves the practicality of the device.

[0005] The present invention provides a drip irrigation device for ecological cultivation of Salvia miltiorrhiza under film, which includes a moving mechanism; it also includes a drip irrigation mechanism and a drainage mechanism, wherein the drip irrigation mechanism is mounted on the moving mechanism and the drainage mechanism is mounted on the drip irrigation mechanism.

[0006] The moving mechanism adjusts the position of the drip irrigation mechanism, which replenishes water to the Salvia miltiorrhiza, while the drainage mechanism drains water from the soil and replenishes air to the roots of the Salvia miltiorrhiza.

[0007] Before planting Salvia miltiorrhiza, the drip irrigation system heats the water to form steam, which is then released into the soil to sterilize it at high temperatures. After planting, the drip irrigation system, in conjunction with a mobile mechanism, provides three-dimensional root drip irrigation to ensure the Salvia miltiorrhiza meets its water needs. In the event of heavy rain or flooding, the drainage system continuously drains water from the soil, removing most of the moisture and providing aeration to the roots to reduce root rot, thus improving the equipment's usability.

[0008] Preferably, the moving mechanism includes two sets of slide rails, two sets of electric sliders, multiple sets of guide columns, two sets of lifting blocks, two sets of first electric cylinders, and a support. Both sets of slide rails are installed on both sides of the field. The two sets of electric sliders are slidably installed on the two sets of slide rails. The multiple sets of guide columns are installed on the tops of the two sets of electric sliders. The two sets of lifting blocks are slidably installed on the multiple sets of guide columns. The bottom ends of the two sets of first electric cylinders are installed on the tops of the two sets of electric sliders, and the top ends of the two sets of first electric cylinders are installed on the two sets of lifting blocks. The support is installed on the two sets of lifting blocks. By sliding the two sets of electric sliders on the two sets of slide rails, the position of the drip irrigation mechanism is adjusted. Then, by retracting the two sets of first electric cylinders, the bottom of the drip irrigation mechanism is driven into the ground to irrigate one row of *Salvia miltiorrhiza* plants. After irrigation, the two sets of first electric cylinders extend, and the above steps are repeated to irrigate other rows of *Salvia miltiorrhiza* plants, thereby improving the practicality of the equipment.

[0009] Preferably, the drip irrigation mechanism includes a water delivery mechanism and multiple conveying mechanisms. The water delivery mechanism is mounted on a set of electric sliders, and the multiple conveying mechanisms are all slidably mounted on a bracket and connected to the water delivery mechanism. Water is discharged into the conveying mechanisms through the water delivery mechanism, allowing the conveying mechanisms to drip irrigate the roots of Salvia miltiorrhiza. Alternatively, the water delivery mechanism can work with the conveying mechanisms to draw out water from the soil, or the water delivery mechanism can transport air to replenish the roots of Salvia miltiorrhiza with air, thereby improving the practicality of the equipment.

[0010] Preferably, the water delivery mechanism includes a heating box, a filter plate, an inlet valve, a first electrically controlled valve, a pressure regulating cylinder, a piston, a second electric cylinder, a second electrically controlled valve, a first delivery pipe, and a second delivery pipe. The heating box is mounted on a set of electric sliders. The filter plate is installed inside the heating box. The inlet valve is installed on the side of the heating box. The pressure regulating cylinder is installed on the top of the heating box via the first electrically controlled valve, and the filter plate is located between the inlet valve and the first electrically controlled valve. The piston is slidably installed inside the pressure regulating cylinder. The second electric cylinder is fixedly installed on the top of the pressure regulating cylinder, and the bottom end of the second electric cylinder is connected to the top end of the piston. The second electrically controlled valve is installed on the piston. One end of both the first delivery pipe and the second delivery pipe is installed on the heating box. One end of the first delivery pipe extends to the bottom of the heating box and is connected to multiple sets of delivery mechanisms. The second delivery pipe is connected to a drainage mechanism. Both the first and second delivery pipes are equipped with solenoid valves. When the inlet valve is connected to a water source, the inlet valve and the first electrically controlled valve are opened. The second electric cylinder contracts, causing the piston to rise and drawing water into the heating box. The system filters impurities from the water using a filter plate. Then, by closing the inlet valve, the second electric cylinder extends to pressurize the heating chamber. Water is then discharged through the first delivery pipe into multiple delivery mechanisms for drip irrigation of the Salvia miltiorrhiza roots. Alternatively, the inlet valve and the solenoid valve on the second delivery pipe are closed. The second electric cylinder then retracts, causing the piston to slide upwards. Closing the second electric cylinder again allows air to be discharged into the heating chamber. This air then enters the multiple delivery mechanisms through the first delivery pipe, replenishing the Salvia miltiorrhiza roots with air. Alternatively, the water is heated in the heating chamber, and the second electric cylinder extends, causing the piston to slide downwards, pressurizing the heating chamber and generating steam. The above steps are repeated, allowing the delivery mechanisms to discharge the steam into the soil for high-temperature sterilization. For drainage, the inlet valve and the solenoid valve on the first delivery pipe are closed. The second electric cylinder retracts, causing the multiple delivery mechanisms to suck out accumulated water from the soil. The water is then discharged through the second delivery pipe to the left side of the heating chamber, thus improving the equipment's practicality.

[0011] Preferably, the conveying mechanism includes a slider, bolts, a fixing frame, a connecting pipe, and multiple sets of drip irrigation pipes. The slider is slidably mounted on the support, the connecting pipe is mounted on the bottom of the slider through the fixing frame, the bolt is threaded onto the slider, and the multiple sets of drip irrigation pipes are all mounted on the connecting pipe. The connecting pipe is connected to the first conveying pipe. By sliding the slider on the support, the position of the slider is adjusted so that the Salvia miltiorrhiza is positioned between the multiple sets of drip irrigation pipes. Then, the bolt is tightened so that the rear end of the bolt presses against the support to limit the slider. Then, by retracting two sets of first electric cylinders, the multiple sets of drip irrigation pipes are inserted into the ground. Then, the first conveying pipe discharges water into the connecting pipe, and then the water is dripped to the area around the Salvia miltiorrhiza roots through the drip irrigation pipes. Alternatively, air is discharged into the connecting pipe, and then discharged to the area around the Salvia miltiorrhiza roots through the drip irrigation pipes to replenish the air to the Salvia miltiorrhiza roots. Or, the drip irrigation pipes, in conjunction with the drainage mechanism, drain the water from the soil, thereby improving the practicality of the equipment.

[0012] Preferably, the drip irrigation system includes an inner drip irrigation tube, a steel rod, an outer drip irrigation tube, a gear ring, a drive motor, and a gear. The top of the inner drip irrigation tube is mounted on a connecting pipe, and the interior of the inner drip irrigation tube communicates with the interior of the connecting pipe. The inner drip irrigation tube has multiple rows of first drip irrigation holes. The steel rod is threaded onto the bottom of the first drip irrigation holes. The outer drip irrigation tube is rotatably fitted onto the inner drip irrigation tube, and the outer drip irrigation tube has a row of second drip irrigation holes. The gear ring is fitted onto the top of the inner drip irrigation tube. The drive motor is fixedly mounted on the connecting pipe, and the gear is mounted on the output shaft of the drive motor, with the side end of the gear meshing with the gear ring. The system retracts via two sets of first electric cylinders. A steel rod is driven into the ground so that all the second drip holes on the outer drip irrigation pipe are underground. Then, the drive motor is turned on, and the outer drip irrigation pipe is rotated through the meshing of the gear and ring gear. This aligns the second drip holes on the outer drip irrigation pipe with the first drip holes on the inner drip irrigation pipe. The discharge direction is adjusted to discharge steam, water, or air into the soil. When Salvia miltiorrhiza roots grow into the first drip holes of the inner drip irrigation pipe and the second drip holes of the outer drip irrigation pipe, the roots can be disconnected by rotating the outer drip irrigation pipe, thus keeping the first drip holes of the inner drip irrigation pipe and the second drip holes of the outer drip irrigation pipe unobstructed and improving the practicality of the equipment.

[0013] Preferably, the drainage mechanism includes multiple sets of third electric cylinders, multiple sets of lifting frames, multiple sets of annular scrapers, multiple sets of suction pipes, and multiple sets of discharge pipes. The multiple sets of third electric cylinders are respectively installed at the top of the multiple sets of inner drip irrigation pipes; the multiple sets of lifting frames are respectively installed at the bottom of the multiple sets of third electric cylinders; the multiple sets of annular scrapers are respectively installed at the bottom of the multiple sets of lifting frames; the multiple sets of suction pipes are respectively installed at the bottom of the multiple sets of lifting frames; one end of each set of discharge pipes communicates with the interior of the multiple sets of suction pipes; and the other end of each set of discharge pipes is connected to the second conveying pipe. Connection; Due to prolonged drip irrigation of the Salvia miltiorrhiza roots, multiple holes are formed around the roots. During heavy rain or flooding, water accumulates in these holes. A steel rod is then inserted into the holes, and the lifting frame is moved to the bottom of the inner drip irrigation pipe via a third electric cylinder. This allows the suction pipe to drain the water into the drain pipe, which then drains the water into the second delivery pipe. During the movement of the lifting frame, a ring scraper cleans the inner wall of the inner drip irrigation pipe, thereby improving the equipment's usability.

[0014] Preferably, the top of the multiple sets of guide columns is equipped with multiple sets of solar generators and solar heating tubes, and the top of the heating box is equipped with a circulation pump. One end of the solar heating tube is connected to the drain outlet of the circulation pump, and the other end of the solar heating tube and the suction outlet of the circulation pump both extend into the interior of the heating box. The solar generator converts solar energy into electrical energy, which, together with the power grid, powers the drip irrigation device. The circulation pump is turned on to make the water in the heating box circulate in the heating box and the solar heating tubes. The water is heated by solar energy, reducing the energy consumption of the heating box and thus improving the practicality of the equipment.

[0015] Preferably, both the first and second conveying pipes are flexible hoses; this facilitates adjustment of the spacing between adjacent sliders, thereby improving the practicality of the equipment.

[0016] Preferably, the outer wall of the inner drip irrigation tube is in close contact with the inner wall of the outer drip irrigation tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. A single set of equipment can sterilize the soil, drip irrigate and drain the water, reducing pests and diseases of Salvia miltiorrhiza, reducing water waste and minimizing the impact of waterlogging on Salvia miltiorrhiza.

[0019] 2. By using the device to drip irrigate the roots of Salvia miltiorrhiza during movement, the installation cost of the drip irrigation equipment is reduced, and the three-dimensional drip irrigation method prevents Salvia miltiorrhiza from growing only towards the dripping point;

[0020] 3. By using solar energy to heat water, the efficiency of steam generation is improved and the energy consumption of 07 is reduced. Attached Figure Description

[0033] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0034] Example 1

[0036] The moving mechanism adjusts the position of the drip irrigation mechanism, which replenishes water to the Salvia miltiorrhiza, while the drainage mechanism drains water from the soil and replenishes air to the roots of the Salvia miltiorrhiza.

[0037] The moving mechanism includes two sets of slide rails 1, two sets of electric sliders 2, multiple sets of guide columns 3, two sets of lifting blocks 4, two sets of first electric cylinders 5, and a bracket 6.

[0040] The delivery mechanism includes a slider 17, a bolt 18, a fixing frame 19, a connecting pipe 20, and multiple sets of drip irrigation pipes. The slider 17 is slidably mounted on the bracket 6, the connecting pipe 20 is mounted on the bottom of the slider 17 through the fixing frame 19, the bolt 18 is threaded onto the slider 17, and the multiple sets of drip irrigation pipes are all mounted on the connecting pipe 20.

[0041] The drip irrigation system includes an inner drip irrigation pipe 21, a steel rod 23, an outer drip irrigation pipe 24, a gear ring 26, a drive motor 27, and a gear 28. The top of the inner drip irrigation pipe 21 is mounted on the connecting pipe 20, and the interior of the inner drip irrigation pipe 21 communicates with the interior of the connecting pipe 20. The inner drip irrigation pipe 21 is provided with multiple rows of first drip irrigation holes 22. The steel rod 23 is threaded onto the bottom of the first drip irrigation holes 22.

The gear 28 is mounted on the output shaft of the drive motor 27, and the side end of the gear 28 meshes with the gear ring 26.

[0042] The drainage mechanism includes multiple sets of third electric cylinders 29, multiple sets of lifting frames 30, multiple sets of annular scrapers 31, multiple sets of suction pipes 32, and multiple sets of discharge pipes 33. The multiple sets of third electric cylinders 29 are respectively installed on the top of the multiple sets of inner drip irrigation pipes 21, the multiple sets of lifting frames 30 are respectively installed on the bottom of the multiple sets of third electric cylinders 29, the multiple sets of annular scrapers 31 are respectively installed on the bottom of the multiple sets of lifting frames 30, the multiple sets of suction pipes 32 are respectively installed on the bottom of the multiple sets of lifting frames 30, one end of the multiple sets of discharge pipes 33 is connected to the interior of the multiple sets of suction pipes 32, and the other end of the multiple sets of discharge pipes 33 is connected to the second conveying pipe 16.

[0043] The position of the drip irrigation mechanism is adjusted by two sets of electric sliders 2 sliding on two sets of slide rails 1 respectively. Then, the two sets of first electric cylinders 5 retract, causing the steel rod 23 to penetrate the mulch film and penetrate into the ground, so that the row of second drip holes 25 on the outer drip irrigation pipe 24 are all underground. Then, the drive motor 27 is turned on, and the gear 28 meshes with the gear ring 26 to drive the outer drip irrigation pipe 24 to rotate, aligning the row of second drip holes 25 on the outer drip irrigation pipe 24 with the row of first drip holes 22 on the inner drip irrigation pipe 21. The discharge direction is adjusted, the water inlet valve 9 is connected to the water source, the water inlet valve 9 and the first electric control valve 10 are opened, and the second electric cylinder 13 retracts, causing the piston 12 to rise and draw water into the heating box. Impurities in the water are filtered through a filter plate 8. The water is then heated in a heating box 7 by closing the inlet valve 9. Simultaneously, the second electric cylinder 13 extends, causing the piston 12 to slide downwards, pressurizing the heating box 7 and generating steam. The steam then passes through the first delivery pipe 15, connecting pipe 20, and inner drip irrigation pipe 21 before being sprayed into the soil. This, in turn, drives the outer drip irrigation pipe 24 to rotate, aligning a row of second drip irrigation holes 25 on the outer drip irrigation pipe 24 with other rows of first drip irrigation holes 22 on the inner drip irrigation pipe 21, thus sterilizing the soil in different directions with high temperature.

During the growth of Salvia miltiorrhiza, by closing the water inlet valve 9, the second electric cylinder 13 extends, causing the piston 12 to slide downwards, pressurizing the heating box 7. Water then passes through the first delivery pipe 15, the connecting pipe 20, and the inner drip irrigation pipe 21, and steam is dripped into the soil, providing three-dimensional drip irrigation for the roots of Salvia miltiorrhiza. When water accumulates in the field, due to the long-term drip irrigation of the Salvia miltiorrhiza roots, multiple holes are formed around the roots, and water accumulates in the holes. Then, the steel rod 23 is inserted into the holes, and the third electric cylinder 29 extends, moving the lifting frame 30 to the bottom of the inner drip irrigation pipe 21. The second electric cylinder 13 then... The contraction causes the piston 12 to slide upward, creating a negative pressure inside the heating box 7. Water is then drained into the drain pipe 33 through the suction pipe 32, and then into the second delivery pipe 16 through the drain pipe 33. During the movement of the lifting frame 30, the inner wall of the inner drip irrigation pipe 21 is cleaned by the annular scraper 31. Then, the water in the heating box 7 is discharged through the water inlet valve 9. The extension of the second electric cylinder 13 causes the piston 12 to slide downward, pressurizing the heating box 7. Air passes through the first delivery pipe 15, the connecting pipe 20, and the inner drip irrigation pipe 21 in sequence, and is then sprayed around the roots of the Salvia miltiorrhiza to replenish the roots with air, reduce root rot, and improve the practicality of the equipment.

Two sets of electric sliders 2 slide on two sets of slide rails 1 to adjust the position of the drip irrigation mechanism. Then, two sets of first electric cylinders 5 retract, causing the steel rod 23 to penetrate the mulch film and penetrate into the ground, ensuring that a row of second drip holes 25 on the outer drip irrigation pipe 24 are all underground. Next, the drive motor 27 is turned on, and through the meshing of gear 28 and gear ring 26, it drives the outer drip irrigation pipe 24 to rotate, aligning the row of second drip holes 25 on the outer drip irrigation pipe 24 with the row of first drip holes 22 on the inner drip irrigation pipe 21. The discharge direction is adjusted, and the inlet valve 9 is connected to the water source. The inlet valve 9 and the first electric control valve 10 are opened, and the second electric cylinder 13 retracts, causing the piston 1... 2. Water is drawn into the heating tank 7 and filtered through the filter plate 8 to remove impurities. Then, by closing the inlet valve 9 and opening the circulation pump 36, the water in the heating tank 7 circulates between the heating tank 7 and the solar heating tube 35, heating the water through solar energy. Simultaneously, the second electric cylinder 13 extends, causing the piston 12 to slide downwards, pressurizing the heating tank 7 and generating steam. The steam then passes through the first delivery pipe 15, the connecting pipe 20, and the inner drip irrigation pipe 21, before being sprayed into the soil. This drives the outer drip irrigation pipe 24 to rotate, aligning one row of second drip irrigation holes 25 on the outer drip irrigation pipe 24 with the other rows of first drip irrigation holes 22 on the inner drip irrigation pipe 21, thus heating the soil in different directions. After sterilization, the first two sets of electric cylinders 5 extend, resetting the inner drip irrigation pipe 21. The electric slider 2 slides, sterilizing the soil at high temperature. After the soil cools, Salvia miltiorrhiza is planted. During the growth process, the water inlet valve 9 is closed, and the second electric cylinder 13 extends, causing the piston 12 to slide downwards, pressurizing the heating box 7. Water then passes through the first delivery pipe 15, connecting pipe 20, and inner drip irrigation pipe 21, dripping steam into the soil for three-dimensional drip irrigation of the Salvia miltiorrhiza roots. When water accumulates in the field, the prolonged drip irrigation creates multiple holes around the roots, allowing water to accumulate. A steel rod 23 is then inserted into these holes, and the third electric cylinder 29 extends, moving the lifting frame 30. The water flows to the bottom of the inner drip irrigation pipe 21. The second electric cylinder 13 contracts, causing the piston 12 to slide upward, creating a negative pressure inside the heating box 7. Water is then drained into the drain pipe 33 through the suction pipe 32, and then into the second delivery pipe 16 through the drain pipe 33. During the movement of the lifting frame 30, the inner wall of the inner drip irrigation pipe 21 is cleaned by the annular scraper 31. Then, the water in the heating box 7 is drained through the water inlet valve 9. The second electric cylinder 13 extends, causing the piston 12 to slide downward, pressurizing the heating box 7. Air passes through the first delivery pipe 15, the connecting pipe 20, and the inner drip irrigation pipe 21 in sequence, and is then sprayed around the roots of the Salvia miltiorrhiza to replenish the roots with air, reduce root rot, and improve the practicality of the equipment.

[0057] The main functions achieved by this invention are: increasing the yield of Salvia miltiorrhiza, improving the growth effect of Salvia miltiorrhiza, and reducing equipment energy consumption;

[0058] 1. Increase the yield of Salvia miltiorrhiza: One set of equipment can sterilize the soil, drip irrigate and drain the water, reduce pests and diseases of Salvia miltiorrhiza, reduce the waste of water resources and reduce the impact of waterlogging on Salvia miltiorrhiza;

[0059] 2. Improve the growth effect of Salvia miltiorrhiza: By using a three-dimensional drip irrigation method, prevent Salvia miltiorrhiza from growing only towards the dripping point;

[0060] 3. Reduce equipment energy consumption: By using solar energy to heat water, the efficiency of steam generation is improved, and the energy consumption of 07 is reduced.
