Description

TECHNICAL FIELD

[0001] The present application relates to the field of plant aerial seeding technology, and particularly relates to a wild field anti-predation seed release device. BACKGROUND

[0002] With the increasing demand for ecological restoration, degraded land management, remote area vegetation restoration and unmanned operation, wild field seed release devices play an important role in large-scale artificial seeding and ecological engineering. Especially in mountainous areas, deserts, wetlands and other areas where humans cannot directly reach, aerial seeding or high-altitude throwing can significantly improve the efficiency of seeding. However, the existing wild field seed release devices still have many deficiencies in structure and function.

[0003] Firstly, during the falling process, due to the lack of effective slow-down and deceleration mechanism, the seeds are easily scratched and the embryo is damaged due to high-speed impact at the moment of landing, which directly affects the germination rate and survival rate. Although some devices are equipped with wing or umbrella-shaped deceleration structures, most of them are fixed or rigidly expanded structures, and the shape is irregular, which is easy to be squeezed and deformed during transportation and stacking, and the slow-down stability is greatly affected by wind direction and air flow fluctuation, and the slow-down effect lacks consistency. Secondly, the seeds in the wild environment face a high risk of predation, and rodents, birds and some insects will eat the seeds within a short time after seeding, resulting in a significant decrease in seeding effect. The existing anti-predation measures mostly rely on manual spraying of repellents or the use of time-release devices, but such methods are difficult to respond in time in remote areas without human attendance, and rely on external energy or electronic control systems, increasing the cost and maintenance difficulty. Although some devices are equipped with independent water tanks or fertilizer tanks, they are difficult to achieve ideal results due to structural separation, trigger delay or uncontrollable release amount. SUMMARY

[0004] The purpose of the present application is to provide a wild field anti-predation seed release device that realizes slow-down and anti-predation functions.

[0005] Technical solution: The wild field anti-predation seed release device provided by the present application comprises an internal hollow and degradable barrel, a plurality of slow-down resistance pieces arranged around the outer barrel for one turn, a storage mechanism for storing repellents and a seed bin inserted into the bottom of the barrel. The inside of the barrel is vertically provided with a driving rod, the lower end of the driving rod is connected to the seed bin, and the upper end of the driving rod is connected to the storage mechanism. When the seed bin falls to the ground, the driving rod moves upward to transfer the impact energy to the storage mechanism, and the repellents in the storage mechanism are released.

[0006] Preferably, it further comprises a nutrient bin arranged on the top of the seed bin, and the bottom of the nutrient bin is provided with a sealed hole.

[0007] Further, the seed bin comprises a bin body for containing seeds and soil, and a directional moving plate connected to the top of the bin body and the upper surface center of the bin body, and the bottom outer wall of the bin body is spherical or sharp. The upper surface of the directional moving plate is provided with a puncture needle corresponding to the position of the sealed hole, and a slow-release flow channel is arranged inside the puncture needle.

[0008] Furthermore, the lower end of the slow descent resistance sheet extends to the outside of the seed bin, and the inner wall of the slow descent resistance sheet is provided with a flexible limiting clamping strip that can be clamped in the active gap between the seed bin and the cylinder. The slow descent resistance sheet is an arc-shaped sheet body with outward expansion on both sides of the bottom, and the back side of the arc-shaped sheet body is thickened in the middle.

[0009] Further, the storage mechanism comprises a medicament bin for storing the repellent, an opening provided at the top of the medicament bin, an elastic sheet connected to the inner wall of the medicament bin, and a release mechanism provided at the opening. The repellent is stored in the medicament bin space above the elastic sheet in a compressed state. The release mechanism comprises a sealing plate covering the opening, a vertical sleeve rod connected to the center of the lower surface of the sealing plate and penetrating the elastic sheet and the top wall of the cylinder, a clamping ring provided at the top edge of the inner cavity of the medicament bin, a plurality of clamping rods arranged in the inner wall of the upper half of the sleeve rod in a horizontally retractable manner, and an elastic driving sheet connected to all the clamping rods and located in the inner cavity of the top of the vertical sleeve rod. At least one protrusion is provided on the bottom end outer wall of the vertical sleeve rod, which is clamped in the inner cavity of the cylinder. The driving rod is inserted into the vertical sleeve rod, and the landing impact kinetic energy is transmitted to the elastic driving sheet through the driving rod. The elastic driving sheet is deformed under pressure to drive the clamping rod to retract horizontally, thereby releasing the clamping ring from limiting the vertical sleeve rod, and opening the sealing plate.

[0010] Advantages: Compared with the prior art, the present application has the following advantages:

[0011] (1) The slow descent structure is composed of a plurality of arc-shaped slow descent resistance sheets arranged equidistantly along the circumferential direction, which are concentrically attached to the outer wall of the cylinder when folded, and automatically expand under the action of airflow during the dropping process, forming a stable air resistance surface, effectively reducing the falling speed, reducing the impact force of the seeds on the ground, and preventing the seeds from being damaged by mechanical damage, thereby affecting germination;

[0012] (2) The release mechanism of the repellent adopts a pure mechanical type landing linkage structure, which does not require external power supply or timing control device, and can be unlocked at the moment of the device landing, and the repellent ball is released quickly, so that the repellent forms a protective barrier around the seeds, effectively preventing rodents and insects from eating and damaging the seeds;

[0013] (3) Through the puncture type sealing and directional moving ring linkage, the device is precisely broken and released at the same time, providing immediate water and nutrient supplement for the seeds, significantly promoting the germination and early growth of the seeds, and improving the survival rate;

[0014] (4) The cooperation design of the slow descent resistance sheet and the limiting clamping strip can reliably lock to prevent mis-triggering during transportation and storage, and can automatically release the limiting in the release stage, so as to ensure that the function modules are smoothly unfolded and normally work, and the safety and reliability of field operation are ensured.

[0023] The technical solutions of the application will be further described below in combination with the drawings.

[0024] The application proposes to integrate the slow descent, predation prevention and nutrient supply functions in a degradable structure, and to realize triggering through mechanical linkage. As shown in the drawings, the application provides a field predation prevention seed release device. The inside of a cylinder 1 is hollow, and is made of degradable materials, such as polylactic acid and starch blended modified materials, paper pulp molding matrix matched with degradable waterproof coating, etc. The degradable materials can naturally decompose after completing the seeding task, reducing environmental pollution. The cylindrical design can realize self-stability of the center of gravity under the action of gravity, which is beneficial to the attitude control in the falling process and the smooth unfolding of the slow descent assembly. The top end of the cylinder 1 is detachably installed with a storage mechanism 2 for storing the repellent, and a trigger type release mechanism 24 is arranged therein. The middle part of the inner cavity is a nutrient bin 5 for storing nutrient solution. The bottom of the cylinder is inserted with a seed bin 3, and the seed bin 3 further has a place 34 for storing seeds and a place 33 for storing soil. A driving rod 4 is vertically arranged in the center of the inner cavity of the cylinder 1.

[0025] As Figures 1 to 3As shown, multiple deceleration plates 11 are equidistantly arranged circumferentially around the outer periphery of the cylinder 1. The upper end of each deceleration plate 11 is connected to the top of the outer wall of the cylinder, and the lower end extends to the periphery of the seed chamber 3 and can be freely unfolded. During the free fall of the device, it automatically unfolds into an umbrella-like structure due to air resistance, increasing wind resistance and achieving deceleration to reduce the impact intensity of the seeds upon landing. The middle part 113 on the back side of the deceleration plate is a thickened area, which is locally reinforced to prevent the plate from completely bending under wind resistance, ensuring the stability of the deceleration effect. The two sides 112 at the bottom are outwardly flared to further increase the unfolded area and enhance wind resistance, thereby realizing the deceleration function. The multiple deceleration plates 11 are tightly attached to the outer wall of the cylinder 1 in a covering form and are concentrically arranged with the cylinder 1, so that the device is completely attached to the main body and maintains a cylindrical shape when not unfolded, which is convenient for transportation and storage. It can be densely stacked without protruding parts, solving the problem of low transportation and loading efficiency caused by irregular structure of field delivery equipment. The inner wall of the slow-descent resistance plate 11 is also provided with a flexible limiting strip 111 that can be locked in the movable gap between the seed chamber 3 and the cylinder 10. When the device falls, the flexible limiting strip 111 can rotate slightly under the action of wind force, thereby disengaging from the movable gap between the seed chamber 3 and the bottom of the cylinder 1, thus avoiding obstructing the deployment of the slow-descent resistance plate 1. In the vertical state, the flexible limiting strip 111 forms a mechanical lock by locking into the movable gap, effectively preventing the accidental displacement of the seed chamber during transportation from triggering the release mechanism 24 of the repellent, thus achieving a dynamic balance between transportation stability and slow-descent deployment function.

[0026] like Figure 4 , Figure 7 , Figure 8As shown, the seed chamber 3 includes a chamber body 31 for containing seeds and soil, and a directional moving plate 32 connected to the top of the chamber body 31 with a drive rod 4 connected to the center of its upper surface. The directional moving plate 32 can slide up and down inside the cylinder 1. The chamber body 31 is spherical or has a pointed bottom. This bottom outer wall shape design utilizes airflow guidance to cause the deceleration resistance plate 11 to unfold, thereby enhancing the wind resistance deceleration effect when the device descends. The soil 33 inside provides a basic environment for the growth of the seeds 34. At the same time, the lifting and lowering cooperation structure between the directional moving ring 32 and the inner cavity of the cylinder 1 ensures the stability of the seed chamber 3's landing and shrinking activities. The nutrient chamber 5 is above the seed chamber 3. The bottom of the nutrient chamber 5 is provided with a sealing hole 51, and a sealing plate is provided inside the sealing hole 51. A puncture needle 6 is provided at the center of the top of the directional moving ring 32, and a slow-release flow channel is provided inside the puncture needle 6. The position of the puncture needle 6 corresponds to that of the sealing hole 51. Before the device is placed on the ground, it forms a sealed protective barrier for the nutrient compartment 5 to prevent accidental leakage of nutrient solution or water. When the device touches the ground, the directional moving ring 32 moves upward under the impact force, causing the puncture needle 6 to precisely puncture the sealing plate inside the sealing hole 51, thereby opening the water release channel. The slow-release flow channel set inside the puncture needle 6 can control the release rate of nutrient solution and water, avoiding large-scale loss in a short period of time and ensuring a continuous water supply for seed growth.

[0027] Storage mechanism 2 is a core component specifically designed for storing and preparing to release the repellent. Agent chamber 21 can be rotated and fixed to the top of cylinder 1 via a threaded sleeve. Repellent balls are stored inside agent chamber 21, and opening 22 is located at the top of agent chamber 21. Elastic sheet 23 is horizontal by default and is located in the upper half of the inner cavity of agent chamber 21. Repellent balls can be stored in agent chamber 21 above elastic sheet 23 under pressure. Release mechanism is located at opening 22.

[0028] Release mechanism 24 controls the release of the repellent, such as Figure 5 , Figure 6As shown, the sealing plate 241 covers the opening 22, sealing the agent compartment and preventing leakage of the repellent when not triggered. One end of the vertical sleeve 242 is connected to the center of the lower surface of the sealing plate 241 and passes through the elastic sheet 23 and the top wall of the cylinder 1. At least one protrusion 246 is provided on the outer wall of the bottom end of the vertical sleeve, which engages with the inner cavity of the cylinder 1. A locking ring 243 and a locking rod 244 cooperate to form a locking mechanism. A locking ring 243 is arranged around the top edge of the agent compartment's inner cavity, cooperating with the locking rod to limit the vertical sleeve 242, thereby fixing the closed state of the sealing plate 241. The locking rods 244 can extend and retract horizontally, installed on the inner wall of the upper half of the vertical sleeve, with at least two in number. Initially, they extend outwards and engage with the locking rings to lock the vertical sleeve and prevent it from moving freely. The elastic drive plate 245 is located in the inner cavity at the top of the vertical sleeve rod and connects all the snap-fit ​​rods. It has the characteristics of compressive deformation and elastic reset. When the seed dispensing device lands, the bottom of the seed chamber touches the ground, and the resulting impact kinetic energy is transmitted to the drive rod. The drive rod is inserted into the vertical sleeve rod, which in turn transmits the kinetic energy to the elastic drive plate inside the sleeve rod. The elastic drive plate deforms under pressure, and the force generated by the deformation drives multiple snap-fit ​​rods to retract horizontally in sync. After the snap-fit ​​rods retract, the original engagement with the snap-fit ​​ring is broken, releasing the snap-fit ​​ring from the vertical sleeve rod's limiting effect. The sealing plate opens, and the reset force of the elastic plate causes the internal repellent ball to be released outward.

[0029] The preferred solution is to design the connection between the vertical sleeve 242 and the sealing plate 241 as an arc-shaped structure. The arc-shaped geometric feature allows the drug ball to be guided by the curved surface when it leaves the sealing plate. Its movement direction changes from the original straight upward throw to a scattering motion along the tangent of the arc. This allows the drug ball to be dispersed in different directions during the release process, achieving circumferential uniform diffusion and avoiding the accumulation of multiple drug balls due to concentrated orientation in a single direction. This improves the uniform coverage of the repellent in the release area.

[0030] All functions of this invention are driven passively through mechanical linkage, which has the advantages of strong anti-interference, good environmental adaptability and low failure rate. It can operate stably under various complex field conditions such as high wind, low temperature and drought, and is suitable for various types of ecological restoration tasks.
