Description

Technical Field

[0001] The invention relates to the technical field of seedling protection, and in particular to an intelligent seedling protection device for restoring vegetation in degraded forest land. Background Art

[0002] Degradation of forest vegetation, a serious challenge in the ecological field, stems from the intertwined influence of multiple factors. Natural factors such as frequent extreme weather events caused by climate change, reduced fertility due to soil erosion, and human factors such as uncontrolled logging, soil compaction and vegetation destruction caused by overgrazing, and habitat loss caused by disorderly reclamation have jointly aggravated the degradation of forest ecosystems. This degradation is not only reflected in the sharp reduction in vegetation species and the extreme simplification of community structure, but also at a deeper level, it has led to a serious decline in biodiversity, which in turn weakened the key role of forests in maintaining ecological balance, such as the weakening of water conservation capacity, the decline of soil retention capacity, and the imbalance of climate regulation function. In the long run, if no effective intervention is taken, degraded forests may further evolve into desertified land, aggravating soil erosion and forming a vicious cycle.

[0003] In order to restore the vegetation of degraded forests, people have proposed and implemented comprehensive strategies including soil improvement, vegetation reconstruction and ecological restoration. In particular, vegetation reconstruction, as the core of restoration work, requires the precise selection of tree species and vegetation types that are adapted to the local environment, and the gradual reconstruction of a healthy, diverse and self-sustaining ecosystem through artificial promotion of natural regeneration or direct artificial afforestation.

[0004] In this process, the importance of seedlings as the ray of hope for ecological restoration is self-evident. They are the cornerstone of vegetation community renewal and bear the heavy responsibility of future forest ecological restoration and biodiversity improvement. However, the fragility of seedlings is also obvious. They are extremely sensitive to growth conditions. Insufficient light, temperature fluctuations, lack of water, poor soil, and invasion of pests and diseases may become obstacles to their normal development. Especially in degraded forests, due to long-term human interference and natural destruction, the growth environment faced by seedlings is particularly harsh.

[0005] In order to overcome these challenges, the innovation and strengthening of protection measures are particularly important. Unfortunately, most of the seedling protection devices currently in widespread use are still at the level of simple protection frame structures. Although such devices can provide physical support and protection to a certain extent, their ability to regulate the microenvironment, promote nutrient absorption, and improve stress resistance is extremely limited, and is far from meeting the complex and changeable growth needs of seedlings.

[0006] In addition, with the development of science and technology, intelligence and automation have become important trends in the agricultural field. However, existing seedling protection devices still have obvious deficiencies in intelligence and automation. They lack intelligent monitoring and control systems, and cannot monitor the growth status and environmental conditions of seedlings in real time and make automatic adjustments based on the monitoring results. This not only increases the difficulty and cost of manual management, but also limits the effectiveness and scope of application of the protection device.

[0007] Therefore, it is necessary to provide an intelligent seedling protection device for restoring vegetation in degraded forest land to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0039] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned description of the drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0040] Please refer to Figure 1-Figure 7 In an embodiment of the present invention, an intelligent seedling protection device for restoring vegetation in degraded forest land is provided, comprising:

[0041] The plug rod 1 has a guide hole 4 inside, both ends of the guide hole 4 pass through the plug rod 1, and the guide hole 4 at the lower part is arc-shaped;

[0042] A liquid storage barrel 2, which is fixed to the top of the insertion rod 1 and communicated with the guide hole 4;

[0043] A valve 3, which is arranged on the plug rod 1 and is used to adjust the opening of the guide hole 4;

[0044] A track assembly 6, which is fixed to a side of the insertion rod 1 close to the seedling and is annular, and the axis of the track assembly 6 is parallel to the axis of the insertion rod 1;

[0045] A moving component 7, which is movably arranged on the track component 6, and the moving component 7 is provided with a visual sensor 8 and a weed remover 9;

[0046] The moving assembly 7 reciprocates at intervals along the track assembly 6, and when the visual sensor 8 detects an abnormality, the reciprocating speed of the moving assembly 7 is increased and the posture of the weed remover 9 is adjusted;

[0047] The weed remover 9 includes a base 91 and a motor 92 . The base 91 is fixed on the moving assembly 7 . The motor 92 is rotatably disposed on the base 91 , and the rotation angle is adjustable. The motor 92 has an output end, and the output end is connected to a rope body 93 .

[0048] During installation, first, insert the rod 1 into the soil of the degraded forest land to ensure that the rod 1 is stable and the lower arc-shaped part of the diversion hole 4 can fully contact the soil to facilitate the uniform distribution of the liquid fertilizer. The liquid storage tank 2 is fixed to the top of the rod 1 and connected to the diversion hole 4 for storing and supplying liquid fertilizer or water. The valve 3 (generally an electric valve) adjusts the opening of the diversion hole 4 to control the flow of liquid fertilizer according to the preset irrigation plan or soil moisture monitoring results. For example, when the soil moisture is lower than the preset threshold, the valve 3 automatically opens, and the liquid fertilizer in the liquid storage tank 2 flows into the soil through the diversion hole 4 to provide the necessary nutrients and water for the seedlings.

[0049] In addition, the mobile component 7 moves back and forth at intervals along the circular path of the track component 6, and the visual sensor 8 monitors the growth environment around the seedlings in real time, including soil moisture, weeds, animals, etc. When the visual sensor 8 detects the growth of weeds or the approach of animals, it immediately increases the moving speed of the mobile component 7 and adjusts the posture of the weeder 9 to prepare for weeding or driving away animals. For example, when weeding, the motor 92 remains in a vertical downward state, and the rope body 93 is driven to rotate by the motor 92, and the rope body is used to chop the weeds to achieve the effect of weeding. In addition, the rotation angle of the motor 92 is adjustable (for example, by an electric telescopic rod or a reduction motor, which will not be repeated here), and the movement trajectory of the rope body 93 can be adjusted according to actual conditions. For example, when driving away animals, the motor 92 is adjusted to make it inclined (refer to Figure 4 ), the rope body 93 is driven to rotate by the motor 92, and the rope body can be used to drive away animals.

[0050] That is to say, in this embodiment, the visual sensor 8 can capture and analyze the image information around the seedlings in real time, including soil moisture, weed growth, possible animal intrusion, etc. Through the built-in image processing algorithm, the visual sensor 8 can automatically identify and determine whether these environmental factors are within the normal range and whether they may have an adverse effect on the growth of the seedlings.

[0051] In this embodiment, the track assembly 6 includes a ring-shaped bottom track 61 and a top track 62, and the bottom track 61 and the top track 62 are fixedly connected by a connecting member 63;

[0052] The mobile assembly 7 comprises:

[0053] Two symmetrically arranged side frames 71, each of which is C-shaped and connected by a plate;

[0054] Four first wheel bodies 72 distributed in a rectangular array, the first wheel bodies 72 are rotatably disposed on the side frame body 71, wherein two first wheel bodies 72 are in contact with the outer peripheral side of the top track 62, and the other two first wheel bodies 72 are in contact with the outer peripheral side of the bottom track 61;

[0055] Four second wheel bodies 73 are distributed in a rectangular array, and the second wheel bodies 73 are rotatably set on the side frame body 71, wherein two second wheel bodies 73 are engaged with the inner circumference of the top track 62, and the other two second wheel bodies 73 are engaged with the inner circumference of the bottom track 61.

[0056] In addition, a rotating shaft 74 is connected between the two second wheel bodies 73 in the same vertical direction, and the rotating shaft 74 is driven by a driver 75 .

[0057] The bottom track 61 and the top track 62 of the track assembly 6 are firmly connected by the connecting piece 63 to form a stable annular path. This structure not only improves the stability of the track assembly 6, but also ensures the stable operation of the moving assembly 7 on the track assembly 6.

[0058] The two second wheel bodies 73 in the same vertical direction are connected by a rotating shaft 74 and driven by a driver 75. In this way, not only the driving structure is simplified, but also the driving efficiency is improved, ensuring that the mobile assembly 7 can respond to the control command quickly and accurately.

[0059] In addition, the structural design of the track assembly 6 and the mobile assembly 7 is simple and clear, and the connection and disassembly between the various components are also very convenient. This makes it possible to quickly find the problem and deal with it when the device needs to be maintained or repaired.

[0060] In this embodiment, a length adjustment component is serially connected in the rope body 93 , and the length adjustment component includes a first column groove 94 , a reset rope 96 and a second column groove 95 which are serially connected in sequence, wherein the second column groove 95 is slidably sleeved on the outside of the first column groove 94 .

[0061] Then, when the motor 92 of the weed cutter 9 drives the rope 93 to rotate or swing, one end of the rope 93 is driven by the motor 92, and the other end moves with the rotation of the output end of the motor 92. In this process, if the speed of the motor 92 increases, the free end of the rope 93 will be subjected to a greater centrifugal force.

[0062] Since the second column groove 95 is slidably sleeved outside the first column groove 94, and the reset rope 96 is connected in series between the two, when the rope body 93 is subjected to centrifugal force, the second column groove 95 will slide on the first column groove 94, thereby changing the stretching degree of the reset rope 96. This sliding and stretching process is actually adjusting the overall length of the rope body 93.

[0063] Specifically, when the speed of the motor 92 increases and the centrifugal force on the rope body 93 increases, the second column groove 95 will slide outward along the first column groove 94, so that the reset rope 96 is stretched, thereby increasing the overall length of the rope body 93. Conversely, when the speed of the motor 92 decreases and the centrifugal force on the rope body 93 decreases, the second column groove 95 will slide inward along the first column groove 94 under the elastic action of the reset rope 96, so that the overall length of the rope body 93 is shortened.

[0064] The length adjustment component uses centrifugal force to dynamically adjust the length of the rope 93. This design enables the weeder 9 to quickly and accurately adjust the length of the rope 93 according to actual needs, thereby improving the efficiency of weeding and driving away animals. Since the length adjustment component has the ability to dynamically adjust the length of the rope, the weeder can be applied to different types of weeds and animal driving needs, thereby improving its scope of application and flexibility.

[0065] Furthermore, a plurality of balls 97 are stored between the first column groove 94 and the second column groove 95 .

[0066] The first column groove 94 is also provided with a plurality of through grooves, which are blocked by the eardrum 98 and are close to the second column groove 95 .

[0067] In this embodiment, the multiple balls 97 stored between the first column groove 94 and the second column groove 95 are designed to cooperate with the eardrum 98 to drive away animals approaching the seedlings by simulating knocking sounds. The working principle of this mechanism is that when the motor 92 drives the rope body 93 to rotate, the ball 97 will roll between the first column groove 94 and the second column groove 95. When the ball 97 rolls to the through-slot position close to the eardrum 98, it may hit the eardrum 98, thereby generating a knocking sound.

[0068] However, under the action of inertial force, the ball 97 may be attached to the side walls of the first column groove 94 and the second column groove 95, especially when they roll to a position close to the through groove. In this case, the ball 97 may not be able to continuously and effectively hit the eardrum 98, thereby affecting the effect of driving away animals.

[0069] To solve this problem, the following optimizations are performed:

[0070] 1. By increasing the number of balls 97 and introducing balls 97 of different sizes, the complexity and randomness of the balls 97 rolling between the first column groove 94 and the second column groove 95 can be increased. In this way, even if some balls 97 are attached to the side wall, other balls 97 may continue to roll and hit the eardrum 98.

[0071] 2. Optimize the shape, size and position of the through slots to make them more easily hit by the ball 97. For example, consider increasing the number of through slots or changing their distribution to increase the frequency and effect of the hits.

[0072] 3. Select materials with low friction coefficient and good elasticity to make the first column groove 94, the second column groove 95 and the ball 97. This can reduce the friction resistance of the ball during rolling, making it easier for them to roll freely in the groove and increase the possibility of hitting the eardrum 98.

[0073] 4. By adjusting the speed and direction of the motor 92, the speed and direction of the ball 97 rolling between the first column groove 94 and the second column groove 95 can be changed. This can make the ball 97 hit the eardrum 98 more frequently and produce a stronger knocking sound to drive away animals.

[0074] Of course, when the driving rope body 93 is rotated, the rotation of the rope body 93 can have the effect of driving away animals.

[0075] In this embodiment, a side hole 5 connected to the diversion hole 4 is further provided on one side of the diversion hole 4 for introducing a flexible auxiliary pipe 10. The flexible auxiliary pipe 10 passes through the side hole 5 and the diversion hole 4 and enters the soil layer.

[0076] In addition, the flexible auxiliary tube 10 includes a tube body 101 , which is flexible and supportive. One end of the tube body 101 is a pointed end, and the other end is provided with an injection head 104 .

[0077] During implementation, the operator can insert the flexible auxiliary tube 10 into the guide hole 4 inside the insertion rod 1 through the bypass hole 5, and adjust its depth and angle to ensure that it can reach the target position.

[0078] The tip design of the flexible auxiliary tube 10 enables it to easily penetrate the soil, while the flexibility and support of the tube body 101 ensure its stability and guidance in the soil. Once the flexible auxiliary tube 10 reaches the predetermined position, the operator can connect the drug delivery device through the injection head 104. Drugs or special liquid substances can be directly delivered to specific locations in the soil through the flexible auxiliary tube 10, such as the roots of the target seedlings or the areas where pests and diseases occur, thereby greatly improving the utilization rate of the drugs, and more effectively treating pests and diseases or promoting the growth of seedlings.

[0079] Furthermore, a plugging plunger 103 is fixedly sleeved on the outside of the tube body 101 for plugging the guide hole 4 . A through hole 102 connecting the inside and outside of the tube body 101 is also opened. The through hole 102 is located between the plugging plunger 103 and the injection head 104 .

[0080] Among them, the blocking plunger 103 is fixedly sleeved on the outside of the tube body 101. When the flexible auxiliary tube 10 is inserted into the diversion hole 4, the blocking plunger 103 can fit tightly against the inner wall of the diversion hole 4. In addition, the through hole 102 is opened on the tube body 101, located between the blocking plunger 103 and the injection head 104, so that the liquid in the diversion hole 4 can also be transported to the deep soil through the inside of the tube body 101, which helps to expand the range of action of the liquid and improve its nourishing or therapeutic effect on the soil and seedlings.

[0081] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
