Description

Technical Field

[0001] This invention relates to the field of forestry and grassland planting technology, specifically an irrigation device for forestry and grassland seedling cultivation. Background Technology

[0002] Forests and grasslands refer to plants that grow in forests and grasslands. They play an important role in the protection and restoration of the ecological environment. Forests and grasslands have functions such as preventing wind erosion and sand fixation, protecting water sources, conserving soil and water, regulating climate, purifying air, and maintaining biodiversity. Irrigation devices provide water for forest and grassland seedlings to promote their growth.

[0003] There are currently two main irrigation methods for irrigating forests and grasslands during the seedling stage: one is to directly irrigate the ground surface by pumping water, and the other is to spray and humidify the forests and grasslands using sprinkler equipment.

[0004] Both existing irrigation methods consume large amounts of water, and since water is directly applied to the ground surface and leaves of trees and grasses, evaporation is significant, resulting in a low proportion of water seeping into the soil. Furthermore, the high-speed water flow during irrigation can cause severe soil erosion, negatively impacting the normal growth of trees and grasses. Summary of the Invention

[0005] The purpose of this invention is to provide an irrigation device for forest and grassland seedling cultivation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An irrigation device for forest and grassland seedling cultivation includes a water storage tank with a water inlet on its surface. Support legs are fixedly installed around the bottom wall of the water storage tank, with rollers rotatably mounted on the bottom ends of the support legs. A handle is located on one side of the water storage tank. Two sets of opposing vertical plates are fixedly installed on the bottom wall of the water storage tank, with an irrigation cylinder rotatably mounted between the two sets of vertical plates. A water guide pipe is fixedly installed on the side wall of the water storage tank, with one end connected to the inner cavity of the water storage tank and the other end connected to the irrigation cylinder. Multiple sets of evenly distributed, annular irrigation pipes are fixedly installed on the surface of the irrigation cylinder, communicating with the inner cavity of the irrigation cylinder. The end of each irrigation pipe away from the irrigation cylinder is tapered, and an irrigation inlet is located on the side of the irrigation pipe away from the irrigation cylinder. A control mechanism that cooperates with the irrigation inlet is located inside the irrigation pipe. The mechanism includes a baffle, a sealing component, and an adjusting component. The baffle is slidably installed on the inner wall of the irrigation pipe. The sealing component is located inside the irrigation pipe and connected to the baffle. The sealing component controls the baffle to be entirely within the irrigation opening, thus keeping the irrigation opening closed. The adjusting component is located on the surface of the irrigation pipe and connected to the baffle. After the irrigation pipe is inserted deep into the soil, the adjusting component, in cooperation with the sealing component, controls the baffle to move outward from the irrigation opening. The irrigation cylinder is equipped with a water injection mechanism that cooperates with the irrigation pipe. The water injection mechanism includes a flow guiding component and a driving component. The flow guiding component is located on the inner wall of the irrigation cylinder and is used to transport water from the irrigation cylinder to the irrigation pipe. The driving component is connected to the flow guiding component and, in cooperation with the flow guiding component, controls the water in the irrigation pipe to flow out from the irrigation opening.

[0008] As a further embodiment of the present invention: the sealing assembly includes a receiving groove located above the pouring port on the inner wall of the pouring pipe, the baffle is slidably installed in the receiving groove in the vertical direction, multiple sets of first support rods are fixedly installed on the inner wall of the pouring pipe, the multiple sets of first support rods are jointly fixedly installed on a top block, a compression spring is fixedly installed on the bottom wall of the top block, a bottom block is fixedly installed on the extension end of the compression spring, a second support rod is fixedly installed on the side wall of the bottom block, and the end of the second support rod away from the bottom block is connected to the baffle.

[0009] As a further aspect of the present invention: the adjusting component includes an annular pad sleeved on the outside of the irrigation pipe, a connecting rod fixedly installed on the bottom wall of the pad, and the end of the connecting rod away from the pad being connected to a baffle.

[0010] As a further aspect of the present invention: the flow guiding assembly includes multiple sets of water guiding cylinders fixedly installed on the inner side wall of the irrigation cylinder, the water guiding cylinders being sleeved on the outside of the irrigation pipe, the side wall of the water guiding cylinders having a water inlet, a piston plate being slidably installed in the inner cavity of the water guiding cylinders, multiple sets of brackets being fixedly installed on the inner side wall of the water guiding cylinders, the multiple sets of brackets being jointly fixedly installed on a support plate, a return spring being fixedly installed on the surface of the support plate, and the extension end of the return spring being connected to the piston plate.

[0011] As a further aspect of the present invention: the driving assembly includes multiple sets of push rods fixedly installed on the surface of the pad, the end of the push rod away from the pad extends slidably into the inner cavity of the irrigation cylinder, the side wall of the water guide cylinder is provided with a groove, and a traction rope is fixedly installed on the bottom wall of the piston plate, the end of the traction rope away from the piston plate passes through the groove and is connected to the top end of the push rod.

[0012] As a further aspect of the present invention: the surface of the irrigation pipe is provided with a soil loosening component located outside the irrigation port. The soil loosening component includes multiple sets of vertical grooves opened on the surface of the irrigation pipe. A soil loosening cone rod is rotatably installed at the bottom of the vertical groove. A positioning spring is fixedly installed in the vertical groove. The extension end of the positioning spring is connected to the soil loosening cone rod. A limiting block located outside the soil loosening cone rod is fixedly installed in the vertical groove.

[0013] As a further aspect of the present invention: a fixing ring is fixedly installed on the surface of the irrigation pipe, and the top rod is slidably connected to the fixing ring.

[0014] As a further aspect of the present invention: a control spring is fixedly installed on the surface of the fixing ring and sleeved on the outside of the irrigation pipe, and the extension end of the control spring is connected to the pad.

[0015] As a further aspect of the present invention: the side wall of the irrigation pipe is provided with an installation groove that communicates with the irrigation port, and the connecting rod is located in the installation groove.

[0016] As a further embodiment of the present invention: the bottom wall of the water storage tank is provided with a cleaning brush that cooperates with the irrigation pipe.

[0017] Compared with existing technologies, the beneficial effects of this invention are: by setting up an irrigation cylinder and an irrigation pipe to work together, the irrigation nozzles on the surface of the irrigation pipe can be controlled to penetrate deep into the soil in sequence, thereby allowing an appropriate amount of water to seep into the soil for irrigation. This solves the problems of current methods that directly irrigate the ground surface and grass leaves, resulting in high water evaporation and a low proportion of water seeping into the soil. Furthermore, the high-speed water flow easily erodes the surface soil, causing severe soil loss.

[0018] By setting up a sealing component and an adjusting component to work together, the opening and closing state of the irrigation port can be easily adjusted. When the irrigation port is inside the soil, it is in a through state to irrigate the roots of the forest and grass. When the irrigation port is above the ground, it is in a closed state to effectively prevent water from flowing to the ground.

[0019] By setting up the flow guiding component and the drive component to work together, the water in the irrigation pipe can be automatically pressurized during the irrigation process, which can effectively increase the water seepage rate and further improve the irrigation effect.

Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 10The diagram shown illustrates the structure of an irrigation device for forestry and grassland seedling cultivation according to an embodiment of the present invention. It includes a water storage tank 1 with a water inlet 11 on its surface. Support legs 12 are fixedly installed around the bottom wall of the water storage tank 1, with rollers rotatably mounted on the bottom ends of the support legs 12. A handle 13 is provided on one side of the water storage tank 1. Two sets of opposing vertical plates 2 are fixedly installed on the bottom wall of the water storage tank 1, with an irrigation cylinder 3 rotatably installed between the two sets of vertical plates 2. A water guide is fixedly installed on the side wall of the water storage tank 1. Pipe 31, one end of which is connected to the inner cavity of the water storage tank 1, and the other end of which is connected to the irrigation cylinder 3. Multiple sets of irrigation pipes 4, evenly distributed in a ring, are fixedly installed on the surface of the irrigation cylinder 3. Each irrigation pipe 4 is connected to the inner cavity of the irrigation cylinder 3. The end of each irrigation pipe 4 away from the irrigation cylinder 3 is tapered, and an irrigation port 41 is provided on the side of the irrigation pipe 4 away from the irrigation cylinder 3. A control mechanism 5, which cooperates with the irrigation port 41, is provided inside the irrigation pipe 4. The irrigation pipe 4 includes a baffle 51, a sealing component 52, and an adjusting component 53. The baffle 51 is slidably installed on the inner wall of the irrigation pipe 4. The sealing component 52 is located inside the irrigation pipe 4 and connected to the baffle 51. The sealing component 52 controls the baffle 51 to be entirely within the irrigation opening 41, thereby controlling the irrigation opening 41 to be in a closed state. The adjusting component 53 is located on the surface of the irrigation pipe 4 and connected to the baffle 51. After the irrigation pipe 4 is inserted deep into the soil, the adjusting component 53 cooperates with the sealing component 52. The control baffle 51 moves outward toward the irrigation port 41. The irrigation cylinder 3 is provided with a water injection mechanism 6 that cooperates with the irrigation pipe 4. The water injection mechanism 6 includes a flow guiding component 61 and a drive component 62. The flow guiding component 61 is located on the inner side wall of the irrigation cylinder 3 and is used to transport the water in the irrigation cylinder 3 to the irrigation pipe 4. The drive component 62 is connected to the flow guiding component 61 and controls the water in the irrigation pipe 4 to flow out from the irrigation port 41 by cooperating with the flow guiding component 61.

[0034] Two sets of vertical plates 2 support and position the irrigation cylinder 3 below the water storage tank 1. The irrigation cylinder 3 supports and positions multiple sets of irrigation pipes 4. During use, an appropriate amount of water is injected into the inner cavity of the water storage tank 1 through the water inlet 11. The water in the inner cavity of the water storage tank 1 flows through the water guide pipe 31 and further into the irrigation cylinder 3. The flow guiding component 61 controls the flow of water from the inner cavity of the irrigation cylinder 3 to the inner cavity of the irrigation pipes 4. Initially, the sealing component 52 controls the baffle 51 to be entirely within the irrigation opening 41, at which time the baffle 51 controls the irrigation opening 41 to be in a closed state. Moving the water storage tank 1 across the grassland causes the water storage tank 1 and the vertical plates 2 to cooperate and thus drive the irrigation cylinder 3 to move synchronously. As the irrigation cylinder 3 moves, it drives the irrigation pipes 4 to move synchronously, inserting them into the soil. As the water storage tank 1 continues to move, batches of irrigation pipes 4 are inserted into the soil in sequence, thus controlling the irrigation cylinder 3 to roll while moving. When the irrigation pipe 4 directly below the irrigation cylinder 3 is inserted into the soil, the irrigation port 41 moves synchronously into the soil. The adjusting component 53 and the sealing component 52 cooperate to control the baffle 51 to move to the outside of the irrigation port 41. At this time, the irrigation port 41 is in a through state, and the water in the irrigation pipe 4 can automatically seep into the soil through the irrigation port 41. Since the outside of the irrigation pipe 4 is filled with soil, the initial seepage speed of the water is slow. At the same time as the irrigation pipe 4 is inserted into the soil, the driving component 62 and the guiding component 61 cooperate to apply pressure to the water in the inner cavity of the irrigation pipe 4, which can quickly discharge the water in the inner cavity of the irrigation pipe 4 through the irrigation port 41 and seep into the soil.

[0035] After one row of irrigation pipes 4 has finished irrigating, the irrigation cylinder 3 continues to roll, pulling the irrigation pipes 4 out of the soil. As the irrigation pipes 4 are pulled out, the sealing component 52 controls the baffle 51 to move back into the irrigation port 41, which then closes again. The flow guiding component 61 controls the water inside the irrigation cylinder 3 to flow back into the irrigation pipes 4, effectively preventing water from flowing out through the irrigation port 41. The continuous rolling of the irrigation cylinder 3 then controls another row of irrigation pipes 4 to be inserted into the soil, continuously delivering a suitable amount of water directly into the soil, effectively preventing water evaporation and promoting direct water absorption by the roots of the forest and grass.

[0036] like Figure 5 , Figure 6 , Figure 8 , Figure 10As shown, in a preferred embodiment of the present invention, the sealing assembly 52 includes a receiving groove 521 located above the pouring port 41 on the inner wall of the pouring pipe 4. The baffle 51 is slidably installed in the receiving groove 521 in the vertical direction. Multiple sets of first support rods 522 are fixedly installed on the inner wall of the pouring pipe 4. The multiple sets of first support rods 522 are jointly fixedly installed on a top block 523. A compression spring 524 is fixedly installed on the bottom wall of the top block 523. A bottom block 526 is fixedly installed on the telescopic end of the compression spring 524. A second support rod 525 is fixedly installed on the side wall of the bottom block 526. The end of the second support rod 525 away from the bottom block 526 is connected to the baffle 51.

[0037] Multiple sets of first support rods 522 position the top block 523, which in turn positions the compression spring 524. The compression spring 524 applies a pushing force to the bottom block 526. The bottom block 526 and the second support rod 525 cooperate to position the baffle 51. At this time, the baffle 51 is entirely inside the irrigation opening 41, which is in a closed state. When the irrigation pipe 4 is inserted into the soil, the adjusting component 53 controls the baffle 51 to move outward from the irrigation opening 41. The baffle 51 drives the bottom block 526 to move synchronously towards the top block 523. At this time, the compression spring 524 is under pressure, and the irrigation opening 41 is in a through state. When the irrigation cylinder 3 continues to roll, thereby pulling the irrigation pipe 4 out of the soil, the adjusting component 53 releases the restriction on the baffle 51. The compression spring 524 applies a pushing force to the bottom block 526, and the baffle 51 moves back into the irrigation opening 41, which is closed again.

[0038] like Figure 5 , Figure 6 , Figure 8 , Figure 10 As shown, in a preferred embodiment of the present invention, the adjusting component 53 includes an annular pad 531 sleeved on the outside of the irrigation pipe 4, and a connecting rod 532 is fixedly installed on the bottom wall of the pad 531. The end of the connecting rod 532 away from the pad 531 is connected to the baffle 51.

[0039] The baffle 51 and the connecting rod 532 cooperate to position the pad 531 on the outside of the irrigation pipe 4. When the irrigation pipe 4 moves into the soil, the pad 531 is pressed against the ground surface. At this time, the pad 531 moves upward relative to the surface of the irrigation pipe 4. The pad 531 and the connecting rod 532 cooperate to pull the baffle 51 into the receiving trough 521. At this time, the irrigation port 41 is in a through state. When the irrigation cylinder 3 continues to roll and pulls the irrigation pipe 4 out of the soil, the ground releases the restriction on the pad 531. The pad 531 and the connecting rod 532 cooperate to release the restriction on the baffle 51. The compression spring 524 applies a pushing force to the bottom block 526, and the baffle 51 moves back into the irrigation port 41, and the irrigation port 41 is closed again.

[0040] like Figure 4 , Figure 5 , Figure 7 , Figure 9 As shown, in a preferred embodiment of the present invention, the flow guiding assembly 61 includes multiple sets of water guiding cylinders 611 fixedly installed on the inner side wall of the irrigation cylinder 3. The water guiding cylinders 611 are sleeved on the outside of the irrigation pipe 4. The side wall of the water guiding cylinder 611 is provided with a water inlet 612. A piston plate 616 is slidably installed in the inner cavity of the water guiding cylinder 611. Multiple sets of brackets 613 are fixedly installed on the inner side wall of the water guiding cylinder 611. The multiple sets of brackets 613 are jointly fixedly installed on a support plate 614. A return spring 615 is fixedly installed on the surface of the support plate 614. The extension end of the return spring 615 is connected to the piston plate 616.

[0041] Multiple sets of brackets 613 position the support plate 614 within the inner cavity of the water guide tube 611. The support plate 614 positions the return spring 615, which applies a thrust to the piston plate 616, located at the end of the inner cavity of the water guide tube 611 away from the irrigation pipe 4. Water from the irrigation tube 3 flows through the inlet 612 into the water guide tube 611, and then automatically flows into the irrigation pipe 4. When the irrigation pipe 4 is inserted into the soil, the drive assembly 62 controls the piston plate 616 to move towards the irrigation pipe 4 within the inner cavity of the water guide tube 611. Once the piston plate 616 has moved to the other side of the inlet 612 and continues to move, it applies a thrust to the water within the water guide tube 611 and the inner cavity of the irrigation pipe 4, quickly expelling the water from the inner cavity of the irrigation pipe 4 through the irrigation port 41 and allowing it to seep into the soil.

[0042] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 As shown, in a preferred embodiment of the present invention, the drive assembly 62 includes multiple sets of push rods 621 fixedly mounted on the surface of the pad 531. The end of the push rod 621 away from the pad 531 slides into the inner cavity of the irrigation cylinder 3. A groove 622 is provided on the side wall of the water guide cylinder 611. A traction rope 623 is fixedly mounted on the bottom wall of the piston plate 616. The end of the traction rope 623 away from the piston plate 616 passes through the groove 622 and is connected to the top end of the push rod 621.

[0043] The pad 531 supports and positions the top rod 621 on the outside of the irrigation pipe 4. When the irrigation pipe 4 moves into the soil, the pad 531 is in close contact with the ground surface. At this time, the pad 531 moves upward relative to the surface of the irrigation pipe 4. The pad 531 pushes the top rod 621 to move synchronously into the inner cavity of the irrigation cylinder 3. As the top rod 621 moves into the inner cavity of the irrigation cylinder 3, it cooperates with the traction rope 623 to pull the piston plate 616 to move in the direction of the irrigation pipe 4 within the inner cavity of the water guide tube 611. As the irrigation cylinder 3 continues to roll, thereby pulling the irrigation pipe 4 out of the soil, the ground releases the restriction on the pad 531. The baffle 51 controls the pad 531 to move downward relative to the surface of the irrigation pipe 4. The pad 531 drives the top rod 621 to move away from the irrigation cylinder 3. At this time, the top rod 621 and the traction rope 623 cooperate to release the restriction on the piston plate 616. The return spring 615 applies a pushing force to the piston plate 616, and the piston plate 616 moves again to the end of the inner cavity of the water guide cylinder 611 away from the irrigation pipe 4. At this time, the water in the irrigation cylinder 3 automatically flows through the inlet 612 into the water guide cylinder 611, and the water in the water guide cylinder 611 automatically flows into the irrigation pipe 4 again.

[0044] like Figure 5 , Figure 10 As shown, in a preferred embodiment of the present invention, the surface of the irrigation pipe 4 is provided with a soil loosening component 7 located outside the irrigation port 41. The soil loosening component 7 includes multiple sets of vertical grooves 71 opened on the surface of the irrigation pipe 4. A soil loosening cone rod 72 is rotatably installed at the bottom of the vertical groove 71. A positioning spring 73 is fixedly installed in the vertical groove 71. The telescopic end of the positioning spring 73 is connected to the soil loosening cone rod 72. A limiting block 74 located outside the soil loosening cone rod 72 is fixedly installed in the vertical groove 71.

[0045] When the irrigation pipe 4 is inserted into the soil, it drives the loosening cone 72 to be inserted into the soil simultaneously. When the irrigation pipe 4 is pulled out, the positioning spring 73 applies a pushing force to the loosening cone 72, and the loosening cone 72 is inserted into the soil outside the irrigation pipe 4. The limiting block 74 further restricts the loosening cone 72, and the loosening cone 72 remains in an inclined state outside the irrigation pipe 4. When the irrigation pipe 4 is pulled out, it drives the loosening cone 72 to be pulled out simultaneously. The loosening cone 72 can efficiently break up and loosen the soil outside the irrigation pipe 4, effectively improving the absorption of water by the roots of forest and grass.

[0046] like Figure 5 As shown, in a preferred embodiment of the present invention, a fixing ring 8 is fixedly installed on the surface of the irrigation pipe 4, and the top rod 621 is slidably connected to the fixing ring 8.

[0047] The fixing ring 8 further positions the top rod 621 on the outside of the irrigation pipe 4, effectively improving the stability of the top rod 621 during movement.

[0048] like Figure 5As shown, in a preferred embodiment of the present invention, a control spring 9 is fixedly installed on the surface of the fixing ring 8 and sleeved on the outside of the irrigation pipe 4, and the extension end of the control spring 9 is connected to the pad 531.

[0049] When the irrigation cylinder 3 continues to roll and thus pulls the irrigation pipe 4 out of the soil, the ground releases the restriction on the pad 531. The control spring 9 applies a pushing force to the pad 531, which can control the pad 531 to quickly move back to its original position.

[0050] like Figure 8 , Figure 10 As shown, in a preferred embodiment of the present invention, the side wall of the irrigation pipe 4 is provided with an installation groove 10 that communicates with the irrigation port 41, and the connecting rod 532 is located in the installation groove 10.

[0051] The entire movement of the connecting rod 532 is within the mounting groove 10, effectively preventing the connecting rod 532 from contacting the soil outside the irrigation pipe 4.

[0052] like Figure 2 , Figure 3 As shown, in a preferred embodiment of the present invention, the bottom wall of the water storage tank 1 is provided with a cleaning brush 14 that cooperates with the irrigation pipe 4.

[0053] The irrigation cylinder 3 drives the irrigation pipe 4 to rotate. When the irrigation pipe 4 rotates to its highest point, the cleaning brush 14 can efficiently clean the soil adhering to the surface of the irrigation pipe 4.

[0054] The working principle of this invention is as follows: Two sets of vertical plates 2 support and position the irrigation cylinder 3 below the water storage tank 1, and the irrigation cylinder 3 supports and positions multiple sets of irrigation pipes 4. During use, an appropriate amount of water is injected into the inner cavity of the water storage tank 1 through the water inlet 11. The water in the inner cavity of the water storage tank 1 flows further into the irrigation cylinder 3 through the water guide pipe 31. The return spring 615 applies a pushing force to the piston plate 616, which is located at the end of the water guide cylinder 611 away from the irrigation pipe 4. The water in the irrigation cylinder 3 flows into the water guide cylinder 611 through the water inlet 612, and the water in the water guide cylinder 611 automatically flows into the irrigation pipe 4. The compression spring 524 applies a pushing force to the bottom block 526, and the bottom block 526 cooperates with the second support rod 525 to position the baffle 51. At this time, the baffle 51 is entirely within the irrigation port 41, and the irrigation port 41 is in a closed state.

[0055] The water storage tank 1 is moved across the grassland. The water storage tank 1 and the vertical plate 2 work together to move the irrigation cylinder 3 synchronously. As the irrigation cylinder 3 moves, the irrigation pipe 4 moves synchronously, inserting itself into the soil. The water storage tank 1 continues to move, and batches of irrigation pipes 4 are inserted into the soil, thus controlling the irrigation cylinder 3 to roll as it moves. When the irrigation pipe 4 directly below the irrigation cylinder 3 is inserted into the soil, the irrigation inlet 41 moves synchronously into the soil. The pad 531 is pressed tightly against the ground surface. At this time, the pad 531 moves upward relative to the surface of the irrigation pipe 4. The pad 531 works with the connecting rod 532 to pull the baffle 51 towards the collection trough 521, at which point the irrigation inlet 41 is in a through-hole state. Water from the irrigation pipe 4 can automatically seep into the soil through the irrigation inlet 41.

[0056] Since the outer side of the irrigation pipe 4 is filled with soil, the initial seepage rate of water is slow. As the irrigation pipe 4 is inserted into the soil, the pad 531 pushes the push rod 621 to move synchronously into the inner cavity of the irrigation cylinder 3. Simultaneously, the push rod 621, moving into the inner cavity of the irrigation cylinder 3, works in conjunction with the traction rope 623 to pull the piston plate 616 within the water guide cylinder 611 towards the irrigation pipe 4. Once the piston plate 616 has moved to the other side of the inlet 612 and continues to move, it exerts a thrust on the water in the water guide cylinder 611 and the inner cavity of the irrigation pipe 4, quickly expelling the water from the inner cavity of the irrigation pipe 4 through the irrigation port 41 and allowing it to seep into the soil. After one row of irrigation pipes 4 has finished irrigating, the irrigation cylinder 3 continues to roll, pulling the irrigation pipes 4 out of the soil. As the irrigation pipes 4 are pulled out, the baffle 51 moves back into the irrigation port 41, which then closes again. Water inside the irrigation cylinder 3 flows back into the irrigation pipes 4, effectively preventing water from flowing out through the irrigation port 41. The continuous rolling of the irrigation cylinder 3 also controls another row of irrigation pipes 4 to be inserted into the soil, continuously delivering a suitable amount of water directly into the soil, effectively preventing water evaporation and promoting direct water absorption by the roots of the forest and grass.

[0057] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments.
