Description

Technical Field

[0001] This invention relates to the field of forest irrigation, and more particularly to an intelligent forestry sprinkler irrigation system and method. Background Technology

[0002] Forest irrigation is a technical measure to replenish the soil moisture required by trees in forest areas in order to improve their growth conditions. It is usually carried out by manual or mechanical methods in different forms of irrigation to replenish the soil moisture of trees and meet their water requirements.

[0003] With the continuous development of the economy and society, people are paying more and more attention to basic urban construction such as greening. Among these methods, transplanting seedlings is one of the most effective ways to improve the green environment. However, when this method is implemented, the following problems often arise:

[0004] First, after transplanting seedlings, it is necessary to maintain sufficient water supply. However, the biggest problem in water supply is that after water is injected into the soil covering the seedling fixing position, the loose soil is difficult to provide sufficient fixing force, and therefore, the seedlings often fall over.

[0005] Secondly, the period after transplanting seedlings is the most vulnerable time for the seedlings themselves. During this period, covering the seedlings with dry grass can be used to keep them warm. However, in reality, after covering with grass, the local temperature rises, and the humid environment, coupled with the difficulty of regularly sterilizing the dry grass, leads to a significant increase in the probability of mold growth in the transplanted area, resulting in seedling diseases and other problems.

[0006] Therefore, based on the irrigation limitations mentioned above, there is a need for an intelligent sprinkler irrigation device that can fix the seedlings after irrigation and provide heat preservation and antibacterial treatment for the seedlings. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent forestry sprinkler irrigation system and method to solve the above-mentioned technical problems.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A forestry intelligent sprinkler irrigation system includes a positioning plate and a support assembly. The support assembly has a slot on the side adjacent to the seedling with an opening larger than the diameter of the seedling. The positioning plate and the support assembly are arranged to rotate vertically. A bladder that can be filled with liquid is provided between the positioning plate and the support assembly. The bladder is installed between the support assembly and the positioning plate. The bladder can be hydraulically driven to drive the support assembly to rotate relative to the positioning plate, either approaching or moving away from it, to cover the soil at the location away from the seedling.

[0010] Preferably, a spray assembly connected to the bag tube is installed on the side of the support assembly facing away from the bag. There are at least two spray assemblies, and a pressing and covering assembly that is slidably adapted to the spray assembly is provided between the spray assemblies. The pressing and covering assembly is slidably adapted to the support assembly.

[0011] Preferably, the support assembly includes a support plate and a slide rail that is slidably adapted to the pressing and covering assembly. The support plate is a plate with an internal cavity. The support plate is rotatably installed at the positioning plate. The slide rail is opened at the end of the support plate facing the spray assembly to limit the movement range of the pressing and covering assembly.

[0012] Preferably, the slot is a U-shaped slot.

[0013] Preferably, the spray assembly includes an infusion pipe, which is a bent pipe, and the bend formed at the bend of the infusion pipe is directly opposite the support assembly. When the support assembly is close to the ground and the infusion pipe forms an angle with the ground, the pressing and covering assembly moves closer to the slot.

[0014] Preferably, the pressing and covering assembly includes a bracket, which is divided into a support plate, a limiting rod and a support plate from top to bottom. The support plate has sliding tubes that are adapted to the sliding of the infusion tube at both ends. The support plate is placed in the inner cavity of the support plate, and a membrane material for covering the soil is installed at one end of the support plate. The membrane material has elastic strips at both ends for supporting the membrane material. The elastic strips are connected to the bracket and are used to cover the soil at the seedling in a surrounding shape when in contact with the seedling.

[0015] Preferably, the spray assembly further includes adapters and nozzles installed at both ends of the infusion tube. The adapters are pipes connected to the capsule, and the nozzles extend outward from the support plate to spray and release the liquid.

[0016] Preferably, the sac includes a sac body, a connecting pipe connected to a liquid pump is provided on one side of the sac body, the sac body is installed between a support plate and a positioning plate, and a shaping plate is installed at the end of the sac body that connects with the support plate and the positioning plate.

[0017] Preferably, the capsule further includes pressure valve heads in a number equal to the number of spray components. The pressure valve heads are installed at the capsule body and are used to deliver liquid inside the capsule body to the spray components.

[0018] A method for using an intelligent forestry sprinkler irrigation system is as follows:

[0019] 1) Adjust the corresponding usage state by changing the shape of the capsule;

[0020] 2) If it is necessary to spray irrigation for seedlings, liquid can be injected into the capsule so that the support plate moves upward relative to the positioning plate as the capsule gradually expands. When the pressure inside the capsule is greater than the limit pressure of the pressure valve head, the liquid is introduced into the infusion tube through the pressure valve head so that spray irrigation can be carried out under the fine division of the nozzle.

[0021] 3) If it is necessary to press down the soil at the location of the seedling, release the pressure of the sac so that when the sac contracts, the support plate will fall relative to the positioning plate until the support plate presses down on the soil at the location of the seedling.

[0022] 4) If it is necessary to cover the soil at the location of the seedlings with a film, the elastic strip can guide the film to wrap around the seedlings while the supporting plate is pressing the soil, based on the fact that the film touches the surface of the seedlings.

[0023] The beneficial effects of this invention are:

[0024] 1. In this invention, when the supporting component falls, it can press down the soil at the planting location of the seedling based on the acceleration due to gravity and the weight of its own materials. After pressing, it can effectively prevent the seedling from falling over due to the loose soil after irrigation. In addition, after the supporting component is pressed down, it can minimize evaporation and maintain the moisture of the planting location.

[0025] 2. The present invention allows the pressing and covering component to slide relative to the spraying component, so that when the support plate presses the soil at the seedling site, the pressing and covering component can be placed at the groove, thereby changing the center of gravity of the entire device and concentrating the pressure to resist strong convective weather such as strong winds.

[0033] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0034] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0035] Example 1

[0036] This embodiment proposes a forestry intelligent sprinkler irrigation system, including a positioning plate 5 and a support component 1. The support component 1 has a slot with an opening size larger than the diameter of the seedling on the side adjacent to the seedling. The positioning plate 5 and the support component 1 are arranged to rotate vertically, and a bladder 4 that can be filled with liquid is provided between the positioning plate 5 and the support component 1. The bladder 4 is installed between the support component 1 and the positioning plate 5, and the bladder 4 can drive the support component 1 to rotate relative to the positioning plate 5 under hydraulic action to press or cover the soil away from the seedling. In addition, a sprinkler component 2 connected to the bladder 4 is installed on the side of the support component 1 facing away from the bladder 4.

[0037] Please refer to Figure 1-6 The capsule 4 serves as an intermediate structure between the support assembly 1 and the positioning plate 5. Its function is to pump liquid into its interior through a liquid pump so that the support assembly 1 can rotate relative to the positioning plate 5 as it expands and deforms. After the pressure of the liquid inside the capsule 4 reaches a certain value, the liquid is transported to the spray assembly 2 for spraying treatment.

[0038] In other words, the capsule 4 is also a control structure for controlling the input or delivery of liquid. The following describes the function of the capsule 4 driving the support assembly 1 during the upward and downward rotation:

[0039] ① When the support component 1 rises, the pressure on the support component 1 is released, which allows the spray component 2 to spray liquid onto the seedling planting position, ensuring that the seedling can obtain the water needed for growth.

[0040] ② After the support component 1 falls, it presses down the soil at the planting location of the seedling based on the acceleration due to gravity and the weight of its own material. After pressing, it can effectively prevent the seedling from falling over due to the loose soil after irrigation. In addition, after the support component 1 is pressed down, it can minimize the evaporation and maintain the moisture of the planting location.

[0041] In specific implementation, at least two spray components 2 are provided, and a pressing and covering component 3 that is slidably adapted to the spray components 2 is provided between the spray components 2. The pressing and covering component 3 is slidably adapted to the supporting component 1.

[0042] Among them, the support assembly 1 includes a support plate 12 and a slide 13 that is slidably adapted to the pressing and covering assembly 3. The support plate 12 is a plate with an internal cavity. The support plate 12 is rotatably installed at the positioning plate 5. The slide 13 is opened at the end of the support plate 12 facing the spray assembly 2 to limit the movement range of the pressing and covering assembly 3.

[0043] The spray assembly 2 includes an infusion pipe 21, which is a bent pipe. The bend formed at the bend of the infusion pipe 21 is directly opposite the support assembly 1. When the support assembly 1 is close to the ground and the infusion pipe 21 forms an angle with the ground, the covering assembly 3 is pressed close to the groove.

[0044] like Figure 1-5 As shown, the pressing force configured in the support component 1 is insufficient to provide sufficient fixing force under strong convective weather such as strong winds. Therefore, by sliding the pressing and covering component 3 relative to the spraying component 2, the pressing and covering component 3 can be placed at the groove when the support plate 12 presses the soil at the seedling, thereby changing the center of gravity of the entire device and concentrating the pressure to resist strong convective weather such as strong winds.

[0045] In this process, the kinetic energy of the pressing and covering component 3 moving toward the slot is that the support plate 12 moves toward the ground (the angle between the support plate 12 and the positioning plate 5 decreases), so that when the infusion tube 21 forms an angle with the ground, the pressing and covering component 3 slides toward the slot, thereby changing the center of gravity.

[0046] In specific implementation, the pressing and covering component 3 includes a bracket 33, which is divided into a support plate, a limiting rod and a support plate from top to bottom. The support plate is equipped with sliding tubes 31 that are adapted to slide with the infusion tube 21 at both ends. The support plate is placed in the inner cavity of the support plate 12, and a membrane material 34 for covering soil is installed at one end of the support plate. The membrane material 34 is provided with elastic strips 32 at both ends for supporting the membrane material 34. The elastic strips 32 are connected to the bracket 33 and are used to cover the soil at the seedling in a surrounding shape when in contact with the seedling.

[0047] like Figure 1-5As shown, in response to the need for heat preservation and reduced water evaporation after seedling transplantation, this application, in conjunction with the sprinkler assembly 2, further realizes the above functions, and these functions can be changed based on irrigation needs. The following is a detailed description of the above functions:

[0048] ① When the support plate 12 moves closer to the positioning plate 5, the membrane material 34 installed at the bracket 33 extends outward toward the slot as the sliding tube 31 slides relative to the infusion tube 21. During the extension movement, when the membrane material 34 touches the seedling surface, the elastic strip 32 induces the membrane material 34 to surround the seedling to cover the soil at the seedling, ensuring the seedling's heat preservation and reducing water evaporation.

[0049] ② When the support plate 12 moves away from the positioning plate 5, the membrane material 34 installed at the bracket 33 moves inward toward the support plate 12 as the sliding pipe 31 slides relative to the infusion pipe 21. During the inward movement, the soil covering the seedling is removed. Firstly, this allows the soil to be aerated, reducing the probability of mold growth. Secondly, it facilitates the spraying component 2 to perform spraying irrigation.

[0050] In specific implementation, the spray assembly 2 also includes an adapter 22 installed at both ends of the infusion pipe 21 and a nozzle. The adapter 22 is a pipe connected to the capsule 4. The nozzle extends outward from the support plate 12 and is used to spray and release liquid. The capsule 4 includes a capsule body 41. A connecting pipe connected to the liquid pump is provided on one side of the capsule body 41. The capsule body 41 is installed between the support plate 12 and the positioning plate 5. A shaping plate 42 is installed at the end of the capsule body 41 that is connected to the support plate 12 and the positioning plate 5.

[0051] like Figure 4-6 As shown, the liquid inside the capsule body 41 is input into the infusion pipe 21 through the adapter 22, so that the liquid is divided into smaller parts under the action of the nozzle, and the liquid is sprayed outward to irrigate the seedlings.

[0052] In a specific implementation, the capsule 4 also includes pressure valve heads 43 in number equal to the number of spray components 2. The pressure valve heads 43 are installed at the capsule body 41 and are used to transport the liquid in the capsule body 41 to the spray components 2.

[0053] like Figure 6 As shown, the pressure valve head 43 can block the connection between the bladder body 41 and the spray assembly 2 within a certain pressure value. However, when the pressure value inside the bladder body 41 is higher than the limit value that the pressure valve head 43 can withstand, the bladder body 41 can act as an intermediate conduction structure to input the liquid inside the bladder body 41 into the spray assembly 2.

[0054] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
