Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traditional Chinese medicine planting irrigation equipment, in particular to a freeze-proof heating irrigation equipment for traditional Chinese medicine planting. BACKGROUND

[0002] As the core resource of China's traditional medicine industry, the planting quality of traditional Chinese medicine directly depends on the stability of the growth environment, and irrigation and freeze-proof measures are the key factors affecting the growth of traditional Chinese medicine. Water is one of the important conditions for the growth and development of traditional Chinese medicine. Insufficient water causes wilting of the plant, which may lead to reduced yield or even death. Excessive water causes stem and leaf overgrowth, delays maturity, and even suffocates the root system. With the promotion of large-scale and standardized planting of traditional Chinese medicine, traditional irrigation equipment has been difficult to meet the fine needs in complex planting scenarios.

[0003] In the prior art, such as patent No. CN120457978A, the lateral position of the drip irrigation pipeline and the length of the branch pipe assembly can be adjusted according to the specific use scenario, thereby expanding the drip irrigation range and meeting the diversified planting needs. However, the existing freeze-proof irrigation equipment mostly uses external heating devices, which is not uniform in heating and has large heat loss. The warm water is prone to rapid cooling during transportation, and some equipment lacks a directional heat preservation structure. The diffusion of warm water causes a large local temperature difference in the soil, which may not achieve the freeze-proof effect due to low temperature, or may burn the root system due to high temperature. In addition, due to the differences in plant type and root distribution of different traditional Chinese medicines, it is impossible to continuously adjust according to the growth needs of the medicines. After expanding the spraying angle, the water volume is not increased synchronously, resulting in insufficient water volume in the edge area. When directional irrigation is performed by reducing the angle, the water volume is not reduced, resulting in local water accumulation. SUMMARY

[0008] Preferably, the shell is provided with a circular hole near one side of the connecting frame, and the density of the circular hole in the vertical direction is from dense to sparse. When the cylinder body is inclined upward, the cylinder body drives the shell to rotate synchronously, so that the circular hole with a relatively dense distribution is directed towards the connecting frame. The high-density circular hole can increase the total amount of water per unit time, ensuring that the upper part of the plant and the roots can obtain sufficient water. When the cylinder body is inclined downward or sprayed close to the ground, the relatively sparse circular hole is directed towards the soil, and the water flow is automatically reduced to avoid water accumulation in the roots of the shallow-rooted medicinal materials, and to prevent the roots from being exposed due to the impact of water flow on the soil. The gradient distribution of the circular hole on the shell is designed to synchronize the angle adjustment and water flow adaptation. The number of gears is two, and the two gears are symmetrically arranged with the middle rod as the center. The number of limiting grooves is multiple, and the multiple limiting grooves are arranged circumferentially on the outer side of the arc block.

The number of partition plates is multiple, and the multiple partition plates are evenly distributed on the limiting cylinder. The outer side of the middle rod is provided with a positioning ring.

The positioning pipe adopts a double-layer structure of the outer shell and the neck pipe, and a sealed interlayer is formed in the middle. A heating pipe is built-in.

The heating pipe is located at the interval between the outer shell and the neck pipe.

[0011] Preferably, the fixing component includes a U-shaped plate, with a vertical plate fixedly connected to the end of the U-shaped plate. A positioning block is fixedly connected to the outer side of the vertical plate, and an elastic plate is fixedly connected to the inner wall of the U-shaped plate. The fixing component is installed on the outer side of the positioning tube to fix the positioning tube. The fixing component wraps around the positioning tube through the U-shaped plate and, together with the axially distributed limiting blocks, constrains the pipeline from both radial and axial directions, preventing the positioning tube from shifting or rotating when impacted by water flow, wind, or soil settlement. The elastic plate on the inner wall of the U-shaped plate is made of aging-resistant silicone material, which can buffer the clamping force during fixing through its own deformation. The bottom buffer pad fits against the bottom of the positioning tube to avoid wear on the outer wall of the pipeline caused by hard contact and to prevent extrusion deformation from affecting the heating and insulation effect. There are two elastic plates, which are symmetrically arranged on both sides of the inner wall of the U-shaped plate.

[0012] This invention provides a frost-prevention heating and irrigation device for the cultivation of Chinese medicinal herbs. It has the following beneficial effects: (I) The anti-freezing heating irrigation equipment for the Chinese medicinal herb planting uses a limiting ring to drive the cylinder and shell to rotate around the middle rod, thereby adjusting the angle of irrigation spraying. The spraying angle can be precisely set according to the plant type and root distribution characteristics of the Chinese medicinal herb, avoiding water flow from washing the roots or leaves and causing diseases.

[0013] (II) The frost-prevention heating irrigation equipment for the cultivation of Chinese medicinal materials has holes that are densely spaced in the vertical direction. When the cylinder is tilted upward, the cylinder drives the shell to rotate synchronously, so that the denser holes face the connecting frame. The high density of holes can increase the total amount of water output per unit time, ensuring that the upper and middle parts of the plant and the roots can obtain sufficient water. When the cylinder is tilted downward or sprayed close to the ground, the sparser holes face the soil, and the water volume is automatically reduced, avoiding water accumulation in the roots of shallow-rooted Chinese medicinal materials.

[0014] (III) The anti-frost heating irrigation equipment for the Chinese medicinal herb planting adopts a trapezoidal block layout with the short side facing the water inlet and the long side facing the straight series end. By utilizing the characteristics of the trapezoidal structure with a wide channel on one side and a narrow channel on the other side, the water flow can be accurately distributed to ensure sufficient water supply for the subsequent multiple sets of series sprinklers.

[0015] (iv) The anti-frost heating irrigation equipment for the Chinese medicinal herb planting uses a U-shaped plate to wrap the positioning pipe with a fixing component and axially distributed limiting blocks to constrain the pipeline from both radial and axial directions, preventing the positioning pipe from shifting or rotating when impacted by water flow, wind, or soil settlement. The elastic plate on the inner wall of the U-shaped plate is made of aging-resistant silicone material, which can buffer the clamping force during fixing through its own deformation. The bottom buffer pad is attached to the bottom of the positioning pipe to avoid wear on the outer wall of the pipeline caused by hard contact and to prevent squeezing deformation from affecting the heating and heat preservation effect.

[0018] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] First embodiment, such as Figures 1 to 8 As shown, the present invention provides a technical solution: a heating irrigation device for preventing frost damage in the cultivation of Chinese medicinal herbs, including a water pipe 1, a positioning pipe 2 fixedly connected to the outside of the water pipe 1, a connecting pipe 4 connected to the end of the positioning pipe 2 away from the water pipe 1, and a fixing member 3 provided on the outside of the positioning pipe 2. Nozzle 5 is fixedly installed on the top of connecting pipe 4; The nozzle 5 includes a fixed tube 51, which is threadedly connected to the connecting tube 4. An electric actuator 57 is installed inside the fixed tube 51. A moving block 52 is fixedly connected to the output end of the electric actuator 57. The moving block 52 is slidably connected to the fixed tube 51. A ring 512 is fixedly connected to the outside of the moving block 52. A water spray assembly 54 is fixedly connected to the outside of the ring 512. A connecting rod 55 is fixedly connected to the top of the fixed tube 51. A connector 53 is fixedly connected to the end of the connecting rod 55 away from the moving block 52. There are multiple connectors 53. Limit rings 514 are fixedly connected to the opposite sides of two adjacent connectors 53. The water spray assembly 54 includes an arc block 541 with a limiting groove 544 on its outer side. A central rod 542 is fixedly connected inside the arc block 541. A housing 5410 is rotatably connected inside the limiting groove 544. The central rod 542 is rotatably connected to the housing 5410. An electric actuator 57 pushes a moving block 52 to slide inside the fixed tube 51, causing the moving block 52 to move the ring 512 and the water spray assembly 54. The connecting rod 55 then moves the limiting plate 531. The movement of the inner protrusion 534 causes the limiting plate 531 to move the limiting rings 514 on both sides of the cylinder 545, causing the limiting rings 514 to rotate the cylinder 545 and the shell 5410 around the central rod 542, thereby adjusting the irrigation spray angle. The spray angle can be precisely set according to the plant type and root distribution characteristics of the Chinese medicinal materials, avoiding water flow washing away the roots or water getting on the leaves and causing diseases. The water pipe 1 is connected to an external water source, and the water source inside the water pipe 1 passes through the positioning pipe 2 and the T-shaped pipe 4. 1. The water source is split into two parts by the trapezoidal block 42 inside the T-shaped pipe 41. The water in the direct direction flows towards the subsequent series-connected nozzles 5, while the water along the inclined side of the trapezoidal block 42 flows towards the nozzles 5. Subsequently, the water enters the interior of the fixed pipe 51, causing it to flow along the guide groove 510 of the moving block 52 into the interior of the extension pipe 56. Thus, the water flows through the extension pipe 56, the connecting frame 546, and the circular hole 5411 on the housing 5410, entering the interior of the housing 5410. Finally, it is ejected from the cylinder 545. The end of the shell 5410 away from the arc block 541 is fixedly connected to the cylinder 545. A connecting frame 546 is provided on one side of the arc block 541. The two ends of the connecting frame 546 are fixedly connected to the arc block 541 and the ring 512 respectively. A gear 543 is fixedly connected to the end of the intermediate rod 542. The gear 543 meshes with the gear of the connecting piece 53. There are two limiting rings 514. The two limiting rings 514 are set on both sides of the cylinder 545 in the vertical direction.

[0020] There are multiple positioning tubes 2. Two adjacent positioning tubes 2 are connected by connecting tubes 4. There are multiple connecting tubes 4. Multiple connecting tubes 4 and positioning tubes 2 are alternately arranged. Multiple connecting tubes 4 and positioning tubes 2 are divided into multiple groups. Multiple groups of connecting tubes 4 and positioning tubes 2 are evenly arranged on the outside of water pipe 1.

[0021] The connecting pipe 4 includes a T-shaped pipe 41. Intermediate pipes 43 are provided at both ends of the T-shaped pipe 41 in the horizontal direction. The intermediate pipes 43 are threadedly connected to the T-shaped pipe 41. The inner side of the intermediate pipe 43 away from the T-shaped pipe 41 is threadedly connected to the outer side of the positioning pipe 2. A trapezoidal block 42 is provided in the middle of the interior of the T-shaped pipe 41. The trapezoidal block 42 is arranged with its short side facing the water inlet and its long side facing the straight-line series end. Utilizing the characteristic of the trapezoidal structure, with one side of the channel being wider and the other side narrower, it achieves precise water flow distribution, ensuring sufficient water supply to subsequent sets of series-connected nozzles. The inclined side of the trapezoidal block 42 provides smooth guidance for the water flow. When the water enters the T-shaped pipe 41 from the water inlet, it flows along the inclined side towards the top nozzle 5, avoiding water flow impact and eddies caused by right-angle flow splitting. The water flows smoothly along the long side of the trapezoidal block without obstruction or circumference, maintaining a laminar flow state and ensuring the stability of the spray angle and water volume of the nozzle 5. The short side of the trapezoidal block 42 is located near the water pipe 1. An intermediate ring 44 is fixedly connected to the middle of the inner side of the intermediate pipe 43. The intermediate ring 44 is located in the gap between the positioning pipe 2 and the T-shaped pipe 41. A buffer ring 45 is fixedly connected to the outer side of the intermediate ring 44. The buffer ring 45 is made of elastic material and fits tightly against the connection gap between the positioning pipe 2 and the intermediate pipe 43, forming a double sealing structure. This prevents the leakage of heated water and reduces heat loss at the gap. There are two buffer rings 45, which are symmetrically arranged with the intermediate ring 44 as the center.

[0022] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 9 to 12 As shown, there are multiple water spray components 54 and multiple connectors 53, which are arranged alternately. An extension pipe 56 is fixedly connected to the bottom of each water spray component 54. A middle block 513 is fixedly connected to the outer side of the moving block 52. The middle block 513 is fixedly connected to the extension pipe 56, which communicates with the connecting frame 546. There are multiple connecting plates 59. A guide groove 510 is provided on the outer side of the moving block 52 near the electric actuator 57. The guide groove 510 is an axial groove structure on the outer side of the moving block 52, precisely aligned with the middle block 513 and the extension pipe 56, forming a flow path between the fixed pipe 51, the guide groove 510, and the middle block 513. The directional flow channel of the extension pipe 56 can concentrate and guide the water flow entering the fixed pipe 51 to the water spray assembly, avoiding the water flow from being dispersed and stagnant in the fixed pipe 51, ensuring that the water flow is efficiently delivered to the shell 5410 and the cylinder 545. It can guide the water flow to form a laminar flow state and avoid turbulence and eddies caused by water flow impact. The guide channel 510 and the intermediate block 513 are located on the same vertical plane. A connecting plate 59 is fixedly connected to the inner wall of the fixed pipe 51 near the electric push rod 57. A protective shell 58 is fixedly connected to the end of the connecting plate 59 away from the fixed pipe 51. The protective shell 58 is located on the outside of the electric push rod 57. The ring 512 is slidably connected to the moving block 52. A baffle 511 is fixedly connected to the top of the moving block 52.

[0023] The shell 5410 has a circular hole 5411 on the side near the connecting frame 546. The holes 5411 decrease in density vertically. When the cylinder 545 tilts upward, it drives the shell 5410 to rotate synchronously, so that the more densely distributed holes 5411 face the connecting frame 546. The high density of holes increases the total water output per unit time, ensuring that the upper and middle parts of the plant and the roots receive sufficient water. When the cylinder 545 tilts downward or sprays close to the ground, the less densely distributed holes 5411 face the soil. The water level automatically decreases to prevent water accumulation at the roots of shallow-rooted medicinal herbs and to prevent water flow from impacting the soil and exposing the roots. Utilizing the gradient distribution design of the circular holes 5411 on the shell 5410, angle adjustment and water level adaptation are completed simultaneously. There are two gears 543, symmetrically arranged around the central rod 542. Multiple limiting grooves 544 are arranged circumferentially on the outer side of the arc block 541. A limiting cylinder 547 is fixedly connected to the inner wall of the cylinder 545 for limiting... A baffle 548 is fixedly connected inside the cylinder 547. Multiple baffles 548 are evenly distributed on the limiting cylinder 547. A positioning ring 549 is provided on the outer side of the intermediate rod 542. The limiting cylinder 547 is an internal tubular structure built into the inner wall of the cylinder body 545, precisely aligned with the circular hole 5411 of the shell 5410, forming a directional flow channel for external irrigation via the circular hole 5411, the limiting cylinder 547, and the external irrigation system. This channel can constrain the water flow to spray in a preset direction, preventing scattering and deviation caused by water flow impact. The adjustment angle is adjusted to ensure that the irrigation coverage is consistent with the adjustment angle. At the same time, the baffles 548 are evenly distributed in the limiting cylinder 547, dividing the flow channel in the limiting cylinder 547 into multiple independent and equal-area diversion channels. When the water flows into the limiting cylinder 547 through the round hole 5411, it is diverted by the baffles 548 to form a uniform water flow bundle, avoiding the single water flow from being too strong or too weak, and ensuring that the water volume per unit area in the spraying area is consistent. The positioning ring 549 is provided with a connecting plate inside, and the positioning ring 549 and the intermediate rod 542 are fixedly connected by the connecting plate.

[0024] The connector 53 includes a limiting plate 531, with a side plate 532 fixedly connected to the outer side of the limiting plate 531. There are two side plates 532, which are symmetrically arranged with the limiting plate 531 as the center. An annular groove 533 is opened in the middle of the outer side of the side plate 532, and the middle rod 542 is located inside the annular groove 533. A protrusion 534 is fixedly connected to the inner side of the limiting plate 531. The gear 543 is engaged with the protrusion 534 for positioning, and the connector 53 has a locking plate 535 for limiting structure. After the angle is adjusted, it is locked firmly and will not loosen or shift under the action of external forces such as water flow impact and wind force, ensuring a constant irrigation coverage area. There are multiple protrusions 534, which are evenly arranged on the limiting plate 531. The limiting plate 531 engages with the outer side of the gear 543 through the protrusions 534. The two ends of the limiting plate 531 are arc-shaped, and the ends of the limiting plate 531 are fixedly connected to the locking plate 535.

[0025] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 13 to 14 As shown, the positioning tube 2 includes a housing 21, the end of which is threaded to the intermediate tube 43. The positioning tube 2 adopts a double-layer structure of housing 21 and necked tube 22, forming a sealed interlayer in the middle, in which the heating tube 23 is built. The sealed interlayer can reduce heat loss to the outside. Combined with the sealing and heat preservation effect of the connecting tube buffer ring 45, it reduces the heat loss of the warm water in the tube in low temperature environment, ensuring that the water flow reaches the nozzle 5 and still maintains a suitable temperature, quickly raising the temperature of the soil root area and avoiding frost damage. The necked tube 22 is fixedly connected inside the housing 21, and the heating tube 23 is set inside the housing 21. The heating tube 23 is located in the gap between the housing 21 and the necked tube 22.

[0026] The fixing component 3 includes a U-shaped plate 31, with a vertical plate 33 fixedly connected to the end of the U-shaped plate 31. A positioning block 32 is fixedly connected to the outer side of the vertical plate 33, and an elastic plate 34 is fixedly connected to the inner wall of the U-shaped plate 31. The fixing component 3 is installed on the outer side of the positioning tube 2 to fix the positioning tube 2. The fixing component 3 wraps around the positioning tube 2 through the U-shaped plate 31, and together with the axially distributed limiting blocks 36, it provides dual radial and axial constraint on the pipeline to prevent the positioning tube 2 from shifting or rotating due to water flow impact, wind force, or soil settlement. The elastic plate 34 on the inner wall of the U-shaped plate 31 is made of aging-resistant silicone material. The clamping force during fixing can be buffered by its own deformation. The bottom buffer pad 35 fits against the bottom of the positioning tube to avoid wear on the outer wall of the pipe caused by hard contact and to prevent extrusion deformation from affecting the heating and heat preservation effect. There are two elastic plates 34, which are symmetrically arranged on both sides of the inner wall of the U-shaped plate 31. The bottom of the inner wall of the U-shaped plate 31 is fixedly connected to the buffer pad 35. The U-shaped plate 31 is fixedly connected to the limiting block 36 along the axial direction of the positioning tube 2. There are multiple limiting blocks 36, which are divided into two groups. The two groups of limiting blocks 36 are symmetrically arranged with the U-shaped plate 31 as the center.

[0027] In use, the electric actuator 57 pushes the moving block 52 to slide inside the fixed pipe 51, causing the moving block 52 to move the ring 512 and the water spray assembly 54. This, in turn, moves the limiting plate 531 and the inner protrusion 534 via the connecting rod 55. The limiting plate 531 then moves the limiting rings 514 on both sides of the cylinder 545, causing the cylinder 545 and the shell 5410 to rotate around the central rod 542. This adjusts the irrigation spray angle, allowing for precise setting of the spray angle based on the plant type and root distribution characteristics of the medicinal herbs, preventing water from washing away the roots or wetting the leaves. In the case of a disease, water pipe 1 is connected to an external water source. The water source inside water pipe 1 passes through positioning pipe 2 and T-shaped pipe 41. The water source is split into two parts by trapezoidal block 42 inside T-shaped pipe 41. The water flow in the direct direction flows towards the subsequent series of nozzles 5, and the water flow along the inclined side of trapezoidal block 42 flows towards nozzles 5. Then the water flow enters the interior of fixed pipe 51, so that the water flow enters the interior of extension pipe 56 along the guide groove 510 of moving block 52. Thus, the water flow passes through extension pipe 56, connecting frame 546 and round hole 5411 on shell 5410, enters the interior of shell 5410, and finally sprays out from cylinder 545.
