Description

Technical Field

[0001] This utility model relates to the field of transplanting technology, and in particular to a device for transplanting vetiver grass. Background Technology

[0002] The vetiver transplanting device is a specialized tool developed specifically for the root system characteristics of vetiver. Its core function is to efficiently separate plants while preserving root integrity. Due to its extensive root system and strong adaptability, vetiver is commonly used in soil and water conservation and ecological restoration. Root integrity is the core factor determining the survival rate of transplanted vetiver, while the amount of soil retained is mainly used as a supplementary measure to mitigate environmental stress. In practice, priority should be given to ensuring root integrity, with a lateral root retention rate >70% and no damage to tillering points. The vetiver transplanting device has a simple structure and low cost, making it suitable for small-scale planting scenarios in soil and water conservation projects and ecological restoration, especially in mountainous or sloping terrain with complex topography. Although it relies on manual operation and has limited efficiency, its portability and adaptability make it widely used in resource-scarce areas.

[0003] Traditional vetiver transplanting equipment suffers from significant design flaws, severely hindering transplanting effectiveness. Firstly, the blades of these tools are typically planar, making them prone to severing the taproot or tearing lateral roots during division. Because vetiver roots are densely fibrous, traditional shovels or tillering pliers lack specific protective designs, resulting in a 15%-20% lateral root damage rate during manual operation. This leads to a sharp decline in the plant's water absorption capacity and a 10%-15% decrease in survival rate. If the tillering point at the root-stem junction is damaged, the plant may even completely lose its regenerative capacity. Secondly, traditional tools lack depth control mechanisms, failing to accurately match the 10-20cm soil layer in the main growth zone of the vetiver root system. The digging depth relies heavily on the operator's experience, often resulting in shallow digging leading to root breakage or deep digging causing time and effort.

[0004] Therefore, this application provides a vetiver transplanting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a vetiver transplanting device that solves the problems of existing vetiver transplanting devices, such as: on the one hand, the rough blade design leads to a high rate of lateral root damage and a decrease in survival rate; on the other hand, the lack of a depth-limiting structure makes shallow digging easy to break roots or deep digging laborious and unable to adapt to the main root growth zone.

[0006] To solve the above-mentioned technical problems, this utility model provides a vetiver transplanting device, including a vehicle body assembly, with a transplanting component disposed at the front end of the vehicle body assembly;

[0007] The vehicle body assembly includes a handle, with an upwardly protruding arc rod connected to the middle of the handle. A fixing block is provided at the end of the arc rod, and the fixing block is connected to a rotatable connecting rod via a hinge shaft. Rollers are provided at both ends of the connecting rod.

[0008] The transplanting assembly includes an arc-shaped plate set on a fixing block, with multiple conical ground stakes evenly distributed along the circumference of the arc-shaped plate.

[0009] A further improvement of this utility model is that a depth limiting baffle is provided on each ground plug, and the plane of the depth limiting baffle is perpendicular to the axis of the ground plug.

[0010] A further improvement to the technical solution of this utility model is that the distance between the depth-limiting baffle and the end of the ground plug is 15cm.

[0011] A further improvement of this utility model is that the arc rod bends upward, and the tangent at the end of the arc rod forms an angle with the axis of the ground insertion, and the angle is ≤20°. When the operator holds the handle and presses down, the angle guides the ground insertion to cut into the soil in an approximately vertical direction, reducing lateral resistance. At the same time, the downward pressure is amplified by the lever effect of the arc rod, reducing the intensity of manual operation.

[0012] A further improvement of this utility model is that the arc plate is a downward-curving ring structure, the curvature of the arc plate is adapted to the distribution radius of the vetiver root system, its curvature radius is 20-30cm, and the arc angle is 120°-150° to adapt to the excavation of the surrounding root system with the main root of the vetiver as the center.

[0013] A further improvement of this utility model is that the distance between adjacent ground insertions is less than 5cm.

[0014] A further improvement of this utility model is that the outer surface of the roller is covered with an elastic rubber layer, the thickness of which is 3-5mm and the surface is provided with anti-slip texture.

[0015] A further improvement of this utility model is that: the handle surface is provided with an anti-slip silicone sleeve, and the outer surface of the silicone sleeve is distributed with honeycomb-shaped grooves to enhance grip.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides a vetiver transplanting device that significantly reduces root damage and greatly improves survival rate. Through the synergistic design of a conical rootstock and an arc-shaped plate, it overcomes the destructive cutting of roots caused by traditional planar shovels. The arc-shaped plate, with a radius of curvature of 20-30cm, is precisely matched to the horizontal distribution of the vetiver root system. Multiple conical rootstocks are evenly distributed circumferentially, with a spacing of <5cm between adjacent rootstocks, forming a closed annular cutting surface. During operation, the rootstocks cut vertically into the soil, completely enveloping the main root and surrounding lateral roots of the vetiver, avoiding the tearing of lateral roots caused by unilateral force in traditional tools. Simultaneously, the downward-curving structure of the arc-shaped plate matches the natural spreading shape of the root system, ensuring the soil clump remains intact after excavation, with a lateral root retention rate >85%. It is particularly effective in protecting tillering points, enhancing plant regeneration capacity by 40%.

[0018] 2. This utility model provides a vetiver transplanting device that allows for precise control of the digging depth of vetiver, adapting to the main root growth zone. A depth-limiting baffle is fixed 15cm above the end of each rootstock. When the baffle contacts the ground, the tip of the rootstock reaches a depth of exactly 15cm, covering the dense root area. Furthermore, the depth-limiting baffle is designed to be perpendicular to the rootstock axis, ensuring uniform force during pressing and avoiding depth deviation caused by tilting.

[0019] 3. This utility model provides a vetiver transplanting device that makes vetiver transplanting and digging operations more labor-saving and efficient, enhancing adaptability to complex terrain. Through optimized arc-bar lever mechanics and vertical cutting guidance, this utility model significantly reduces labor intensity and improves efficiency. The design of an angle ≤20° between the tangent of the arc-bar end and the axis of the ground stake ensures that when the operator presses down the handle, the ground stake cuts into the soil in a near-vertical direction, reducing lateral resistance by 40%-50%. Simultaneously, the lever effect of the arc-bar amplifies the downward pressure by 1.5-2 times, reducing the digging time in hard red soil areas from 3 minutes with traditional tools to 1 minute. The roller assembly is covered with a 3-5mm elastic rubber layer, enabling operation on slopes ≤25°, and, combined with the flexible steering of the articulated linkage, achieves stable movement on rugged terrain.

[0020] 4. This utility model provides a vetiver transplanting device that optimizes operational comfort from an ergonomic perspective, solving the muscle strain problem caused by traditional tools. The non-slip silicone sleeve on the handle surface provides a high-friction grip, ensuring stable operation even with wet hands. The upward-curving design of the arc rod allows the operator to maintain a natural standing posture without bending over or excessively bending their arms. Furthermore, the elastic rubber layer on the rollers absorbs ground vibrations during movement, reducing impact load on the arms. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will be further explained below with reference to specific embodiments.

[0031] like Figures 1-4 As shown, this embodiment provides a vetiver transplanting device, including a vehicle body assembly 1, with a transplanting assembly 2 at the front end of the vehicle body assembly 1. The vehicle body assembly 1 includes a handle 11, with an upwardly protruding arc rod 12 connected to the middle of the handle 11. A fixing block 13 is provided at the end of the arc rod 12, and the fixing block 13 is connected to a rotatable connecting rod 14 via a hinge shaft. Rollers 15 are respectively provided at both ends of the connecting rod 14. The outer surface of the rollers 15 is covered with an elastic rubber layer with a thickness of 3-5mm and an anti-slip texture. The surface of the handle 11 is provided with an anti-slip silicone sleeve, and the outer surface of the silicone sleeve is distributed with honeycomb-shaped grooves to enhance grip. This device optimizes operating comfort from an ergonomic perspective and solves the problem of muscle strain caused by traditional tools. The anti-slip silicone sleeve on the surface of the handle 11 provides a high-friction grip surface, allowing for stable operation even when hands are wet. The upward bending design of the arc bar 12 allows the operator to maintain a natural standing posture without bending over or excessively bending the arm. In addition, the elastic rubber layer of the roller 15 absorbs ground vibrations during movement, reducing the impact load on the arm.

[0032] like Figure 1 , Figure 3 , Figure 4 As shown, in this embodiment, the transplanting component 2 includes an arc-shaped plate 21 mounted on a fixing block 13. Multiple conical rootlets 22 are evenly distributed circumferentially on the arc-shaped plate 21, with a spacing of less than 5 cm between adjacent rootlets 22. Each rootlet 22 is equipped with a depth-limiting baffle 23, the plane of which is perpendicular to the axis of the rootlet 22. The distance between the depth-limiting baffle 23 and the end of the rootlet 22 is 15 cm. The depth-limiting baffle 23 allows for precise control of the digging depth of the vetiver, adapting to the main root growth zone. The depth-limiting baffle 23 is fixed 15 cm above the end of each rootlet 22. When the baffle 23 contacts the ground, the tip of the rootlet 22 reaches a depth of exactly 15 cm, covering the dense root area. Furthermore, the design of the depth-limiting baffle 23 being perpendicular to the axis of the rootlet 22 ensures uniform force distribution during pressing and avoids depth deviation caused by tilting.

[0033] like Figure 1 , Figure 3, Figure 4 As shown, in this embodiment, the arc rod 12 bends upward, and the tangent at the end of the arc rod 12 forms an angle with the axis of the ground insertion 22, with the angle being ≤20°. When the operator holds the handle 11 and presses down, the angle guides the ground insertion 22 to cut into the soil in an approximately vertical direction, reducing lateral resistance. At the same time, the lever effect of the arc rod 12 amplifies the downward pressure, reducing the intensity of manual operation. This device makes the transplanting and digging of vetiver grass labor-saving and efficient, enhances adaptability to complex terrain, and significantly reduces labor intensity and improves efficiency through the lever mechanics optimization and vertical cutting guidance of the arc rod 12. The design of the angle between the tangent at the end of the arc rod 12 and the axis of the ground insertion 22 being ≤20° ensures that when the operator presses down the handle 11, the ground insertion 22 cuts into the soil in an approximately vertical direction, reducing lateral resistance by 40%-50%. At the same time, the lever effect of the arc rod 12 amplifies the downward pressure by 1.5-2 times, reducing the time for a single digging in hard red soil areas from 3 minutes with traditional tools to 1 minute. The roller 15 assembly is covered with a 3-5mm elastic rubber layer, which can withstand slope operation with a gradient of ≤25°. Combined with the flexible steering of the articulated link 14, it can achieve stable movement on rugged terrain.

[0034] like Figure 1 , Figure 3 , Figure 4 As shown, in this embodiment, the arc-shaped plate 21 is a downward-curving ring structure. The curvature of the arc-shaped plate 21 is adapted to the distribution radius of the vetiver root system, with a radius of curvature of 20-30cm and an arc angle of 120°-150°, used to dig around the vetiver main root as the center. The ground-insertion 22 significantly reduces the root damage rate of vetiver and greatly improves the survival rate. Through the synergistic design of the conical ground-insertion 22 and the arc-shaped plate 21, the destructive cutting of the root system by traditional planar shovels is overcome. The arc-shaped plate 21, with a radius of curvature of 20-30cm, is precisely matched according to the horizontal distribution range of the vetiver root system. Multiple conical ground-insertions 22 are evenly distributed around the circumference, with a spacing of <5cm between adjacent ground-insertions 22, forming a closed ring-shaped cutting surface. During operation, the ground-insertion 22 cuts into the soil vertically, completely wrapping the vetiver main root and surrounding lateral roots, avoiding the tearing of lateral roots caused by unilateral force in traditional tools. Meanwhile, the downward bending structure of the arc plate 21 is compatible with the natural spreading shape of the root system, ensuring that the soil ball remains intact after excavation, with a lateral root retention rate of >85%, and is particularly effective in protecting the tillering point, enhancing the plant's regeneration capacity by 40%.

[0035] This utility model also provides a working principle for a vetiver transplanting device:

[0036] The operator holds the handle 11 of the vehicle body component 1 and moves the device to the side of the vetiver plant to be transplanted via the rollers 15. The operator adjusts the arc plate 21 to surround the main root of the plant. The operator tightens the handle 11 to apply downward pressure, and the lever force is transmitted through the upward-curving arc rod 12 to drive the multiple conical ground stakes 22 of the transplanting component 2 to cut vertically into the soil. At this time, the depth limiting baffle 23 contacts the ground to limit the cutting depth of the ground stakes 22 to 15cm, ensuring that the main root growth area is covered. The arc plate 21 guides the ground stakes 22 to form a ring-shaped cutting surface along the circumference. After completely wrapping the plant roots, the operator pulls the handle 11 backward. The hinged connecting rod 14 drives the rollers 15 to assist in lifting the device, so that the roots are completely separated from the surrounding soil. Finally, the plant with soil is transferred to the planting hole, and the device is reset to continue the operation for the next plant. The entire process is made easier by the anti-slip silicone handle 11 and the elastic rollers 15, which are suitable for complex terrains such as slopes and hard soil.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
