Description

Technical Field

[0001] This utility model relates to a directional root-cutting device, specifically a low-disturbance directional root-cutting device for Artemisia annua, belonging to the field of urban ecological governance technology. Background Technology

[0002] Artemisia, a common annual allergen in urban ecosystems, has a well-developed root system and strong sprouting ability. Its taproot penetrates vertically into the soil, while its lateral roots are concentrated in the 10-20 cm soil layer. Traditional manual removal methods easily leave rootstocks, leading to rapid recurrence, while chemical control methods cause soil pollution and disrupt the ecological balance. Neither of these methods can meet the green needs of urban ecological governance.

[0003] A public announcement (CN221887080U) discloses a mechanical removal device for Artemisia argyi. This device is fixed to the operator's waist with a belt. After identifying Artemisia argyi with a camera, it cuts the above-ground support with a shearing blade and then digs out the underground root system with a root-removing pick, which improves the thoroughness of removal to a certain extent. However, the above-mentioned existing technical solutions have the following shortcomings: When using the above-mentioned removal device, the root removal method relies on the manual insertion of a root-removing pick into the soil for digging. It is difficult to accurately control the cutting depth and angle, and the root system is prone to incomplete excavation. It can only achieve the cutting and digging of Artemisia argyi, without considering the ecological restoration needs after removal. The soil gaps in the Artemisia argyi growing area can easily lead to the germination of new Artemisia argyi seeds or the invasion of other weeds, which cannot fundamentally reduce the recurrence rate. Utility Model Content

[0004] The purpose of this invention is to provide a low-disturbance directional root-cutting device for Artemisia vulgaris in order to solve the problems of insufficient precision in manual soil digging with root-removing picks, lack of ecological restoration, difficulty in controlling recurrence rate and accidental damage.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a low-disturbance wormwood directional root cutting device, including a handheld rod;

[0006] A hollow inclined support sleeve is welded and fixed to one side of the bottom of the handheld pole. A connecting sleeve is rotatably connected to the surface of the hollow inclined support sleeve. An insertion groove is opened on the surface of the connecting sleeve. A root cutting knife is inserted into the insertion groove and fixed with bolts. A hydraulic rod is hinged to the surface of the hollow inclined support sleeve. The piston end of the hydraulic rod is hinged to the surface of the connecting sleeve.

[0007] The root cutter is inserted into the soil at a 45° angle to cut the main root of the wormwood at an oblique depth of 10-20 cm.

[0008] As a further embodiment of this utility model: a groove is provided at the bottom of the handheld handle, an adjusting slide rod is slidably connected in the groove, a fixing block is fixed on one side surface of the handheld handle, an adjusting screw is rotatably connected to the surface of the fixing block, a screw block is threadedly connected to the outer surface of the adjusting screw, the screw block is fixedly installed on the outer surface of the adjusting slide rod, and the bottom end of the adjusting screw is rotatably connected to a fixing block 2 fixedly installed on one side of the bottom of the handheld handle.

[0009] As a further improvement of this utility model, a ground plug is fixedly installed at the bottom end of the adjusting slide rod.

[0010] As a further improvement of this utility model, a foot pedal is fixedly installed on one side of the bottom end of the adjusting slide rod.

[0011] As a further improvement of this utility model: a protective cover is fixedly installed on one side of the hand handle, the protective cover is placed on the outside of the root cutting knife, and the protective cover is made of transparent material.

[0012] As a further embodiment of this utility model: a seed storage box is installed on one side of the hollow inclined support sleeve. The seed storage box contains pre-stored seeds of competing plants. A baffle is slidably connected to the bottom opening of the seed storage box. A U-shaped connecting slide plate is slidably connected to the surface of the seed storage box. One end of the U-shaped connecting slide plate is connected to the baffle, and a reset spring for resetting the baffle is sleeved on the two parallel sections of the U-shaped connecting slide plate.

[0013] As a further embodiment of this utility model: a U-shaped slide is fixedly installed on one side surface of the handheld rod, a lifting rod is slidably connected to the surface of the U-shaped slide, and a spring for resetting the lifting rod is sleeved on the surface of the U-shaped slide. A wedge is fixed on one side of the bottom end of the lifting rod, the wedge is used to contact the U-shaped connecting slide plate and drive the baffle to slide to one side. The top end of the lifting rod extends to the bottom of the handle of the handheld rod, and a fixed guide block is slidably connected to the surface of the lifting rod. The fixed guide block is fixedly installed on one side surface of the handheld rod.

[0014] As a further improvement of this utility model: a guide plate is installed obliquely on one side surface of the hollow inclined support sleeve. The guide plate is located below the bottom opening of the seed storage box and is used to guide the discharged seeds into the soil cut formed by the root cutting knife.

[0015] The beneficial effects of this utility model are: the core root-cutting structure is compatible with the root distribution characteristics of Artemisia annua, and the root-cutting knife cuts into the soil at a 45° angle for 10-20 cm, which can simultaneously cut off the main root and the concentrated lateral roots, blocking nutrient transport from the root source. The root-cutting depth is precise and controllable, avoiding the problem of recurrence caused by root residue. The work efficiency is far superior to the traditional manual pulling and deep plowing root-killing methods, greatly reducing the work time and labor costs.

[0016] The device precisely controls the cutting depth and angle to avoid excessive soil disturbance caused by excessively deep operations, thus protecting the soil microbial community structure and ecological balance. It is suitable for ecologically sensitive areas such as urban peripheries, green belts, and parks. It does not use any chemical agents, eliminating the risk of soil pollution at the source and conforming to the concept of green ecological governance. At the same time, the combination design of ground insertion and foot pedal ensures the stability of operation in soft soil, gentle slopes and other scenarios, further expanding the application range of the device.

[0017] The handheld handle and various functional components are rationally arranged, allowing operators to hold and operate it with one hand. The foot pedal structure facilitates quick and easy ground planting, and the lifting rod design enables convenient seed release. The entire process does not require frequent changes in posture, significantly reducing labor intensity. The integrated design of root cutting and planting, through components such as seed storage boxes and guide plates, allows for the immediate sowing of competing plants after root cutting. This utilizes root competition to inhibit the sprouting of Artemisia selengensis, consolidating the eradication effect and reducing the risk of recurrence the following year. The root cutting blade uses a plug-in and bolt fixing method, making disassembly and replacement convenient. Each moving part is equipped with a return spring, simplifying the operation process and balancing the needs of short-term efficient treatment and long-term ecological maintenance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1 to 9 As shown, a low-disturbance wormwood directional root cutting device includes a handheld rod 1;

[0031] A hollow inclined support sleeve 10 is welded and fixed to one side of the bottom of the handheld rod 1. A connecting sleeve 12 is rotatably connected to the surface of the hollow inclined support sleeve 10. An insertion groove 13 is opened on the surface of the connecting sleeve 12. A root cutting knife 14 is inserted into the insertion groove 13 and fixed by bolts. A hydraulic rod 11 is hinged to the surface of the hollow inclined support sleeve 10. The piston end of the hydraulic rod 11 is hinged to the surface of the connecting sleeve 12.

[0032] The root cutter 14 cuts into the soil at a 45° angle to obliquely sever the main root of Artemisia, with a cutting depth of 10-20 cm.

[0033] A hollow inclined support sleeve 10, welded and fixed to one side of the bottom of the handheld rod 1, provides a rotational support point for the connecting sleeve 12 and, through its inclined design, adapts to the 45° cutting angle requirement of the root cutting blade 14, eliminating the need for an additional angle adjustment structure and simplifying the device layout. The connecting sleeve 12, rotatably connected to the surface of the hollow inclined support sleeve 10, can drive the root cutting blade 14 to swing flexibly around the hollow inclined support sleeve 10, achieving precise drive of the root cutting action in conjunction with the hydraulic rod 11. The insertion groove 13 on the surface of the connecting sleeve 12 is used to install the root cutting blade 14 by insertion and bolt fixing, which not only facilitates the quick disassembly and replacement of the root cutting blade 14, but also ensures the firm connection between the blade and the connecting sleeve 12 during the root cutting process, preventing loosening and root cutting deviation. The hydraulic rod 11, hinged to the surface of the 10, has its piston end hinged to the surface of the connecting sleeve 12, which converts the linear motion driven by hydraulics into the rotational swing of the connecting sleeve 12. The hydraulic drive method has the characteristics of sufficient power and stable output, and can easily cut into the soil to a depth of 10-20 cm to ensure that the main root of the wormwood is cut off. The root cutting knife 14 is designed to cut into the soil at a 45° angle, which is in line with the characteristics of the vertical distribution of the main root of the wormwood and the concentration of lateral roots in the 10-20 cm soil layer. The oblique cutting can cut off the main root and the surrounding lateral roots at the same time, blocking nutrient transport and improving the eradication effect. Moreover, the cutting depth of 10-20 cm is precisely matched to the key distribution layer of the wormwood root system, avoiding excessive soil disturbance caused by cutting too deep or root residue caused by cutting too shallow.

[0034] Furthermore, a groove 2 is provided at the bottom of the handheld lever 1, and an adjusting slide rod 3 is slidably connected in the groove 2. A fixing block 6 is fixed on one side surface of the handheld lever 1, and an adjusting screw 7 is rotatably connected to the surface of the fixing block 6. A screw block 8 is threadedly connected to the outer surface of the adjusting screw 7, and the screw block 8 is fixedly installed on the outer surface of the adjusting slide rod 3. The bottom end of the adjusting screw 7 is rotatably connected to the fixing block 9 fixedly installed on one side of the bottom of the handheld lever 1.

[0035] The groove 2 at the bottom of the handheld lever 1 provides a sliding guide for the adjusting slide rod 3, ensuring the linearity of the adjusting slide rod 3 during vertical movement and preventing deviation. The adjusting slide rod 3, which is slidably connected within the groove 2, changes the overall support height of the device by sliding up and down, adapting to different working scenarios and meeting the fine-tuning needs of the root cutting depth, thus improving the versatility of the device. The adjusting screw 7 is threadedly connected to the screw block 8 fixed on the outer surface of the adjusting slide rod 3, converting the rotational motion of the adjusting screw 7 into the linear lifting motion of the adjusting slide rod 3. The threaded transmission has the characteristics of high adjustment accuracy and good self-locking, which can accurately control the displacement of the adjusting slide rod 3, thereby achieving precise pre-adjustment of the root cutting depth. Moreover, after adjustment, no additional locking structure is required to maintain the current height, making operation convenient.

[0036] Furthermore, a ground plug 4 is fixedly installed at the bottom of the adjusting slide bar 3.

[0037] The ground plug 4, which is fixedly installed at the bottom of the adjusting slide bar 3, can be inserted into the soil to form a stable support point, fixing the device to the ground. This prevents the hydraulic rod 11 from driving the root cutting blade 14 to exert force during root cutting operations, thus avoiding displacement or tipping of the entire device. It ensures the accuracy of the root cutting blade 14's cutting position, and is especially suitable for operation scenarios with soft soil or gentle slopes.

[0038] Furthermore, a foot pedal 5 is fixedly installed on one side of the bottom end of the adjusting slide bar 3.

[0039] The foot pedal 5, which is fixedly installed on one side of the bottom of the adjusting slide bar 3, provides a fulcrum for the operator to apply force. The operator can quickly and effortlessly insert the ground plug 4 into the soil by stepping on the foot pedal 5, without having to manually press the adjusting slide bar 3, thus reducing the intensity of operation and improving the efficiency of device fixation. It is especially suitable for scenarios where the ground plug 4 needs to be inserted into the soil at a relatively deep depth to ensure the fixation effect.

[0040] Furthermore, a protective cover 15 is fixedly installed on one side of the handheld lever 1. The protective cover 15 covers the outside of the root cutting knife 14 and is made of transparent material.

[0041] A protective cover 15 is fixedly installed on one side of the handheld pole 1, covering the outside of the root cutting blade 14. It can effectively block soil debris, stones and other debris that are splashed during root cutting operations, avoid personal injury to the operator, and improve the safety of the operation. The protective cover 15 is made of transparent material, which does not affect the operator's observation of the cutting position and root cutting status of the root cutting blade 14, making it easy to adjust the operation in real time, while maintaining the integrity of the protective function.

[0042] Example 2

[0043] Improvements based on Example 1:

[0044] Furthermore, a seed storage box 16 is installed on one side of the hollow inclined support sleeve 10. The seed storage box 16 contains pre-stored seeds of competing plants. A baffle 17 is slidably connected to the bottom opening of the seed storage box 16. A U-shaped connecting slide plate 18 is slidably connected to the surface of the seed storage box 16. One end of the U-shaped connecting slide plate 18 is connected to the baffle 17, and a reset spring 19 for resetting the baffle 17 is sleeved on the two parallel sections of the U-shaped connecting slide plate 18.

[0045] A seed storage box 16 installed on one side of the hollow inclined support sleeve 10 is used to pre-store seeds of competing plants such as alfalfa, realizing integrated root cutting and planting operations without the need to carry additional seeds and planting tools, thus improving work efficiency. The seed storage box 16 is positioned close to the root cutting knife 14, facilitating direct seeding into the root cutting cut. A baffle 17 slidably connected to the bottom opening of the seed storage box 16 allows for opening and closing of the opening. During operation, the opening is opened to release the seeds, ensuring seed storage safety and effective use. A U-shaped... The connecting slide plate 18 is connected to the baffle 17 at one end. It can drive the baffle 17 to move synchronously by sliding itself. The U-shaped structure design makes the force on the slide plate more balanced, avoids jamming when sliding, and ensures the smooth opening and closing of the baffle 17. The reset springs 19 sleeved on the two parallel sections of the U-shaped connecting slide plate 18 can automatically pull the U-shaped connecting slide plate 18 and the baffle 17 to reset after the seed is released, and close the bottom opening of the seed storage box 16 without manual reset, simplifying the operation process. Moreover, the elastic force of the reset spring 19 is stable, which can ensure the sealing effect after the baffle 17 is reset.

[0046] Furthermore, a U-shaped slide 20 is fixedly installed on one side surface of the handheld lever 1. A lifting rod 22 is slidably connected to the surface of the U-shaped slide 20, and a spring 21 for resetting the lifting rod 22 is sleeved on the surface of the U-shaped slide 20. A wedge 23 is fixed to one side of the bottom end of the lifting rod 22. The wedge 23 is used to contact the U-shaped connecting slide plate 18 and drive the baffle 17 to slide to one side. The top end of the lifting rod 22 extends to the bottom of the handle of the handheld lever 1, and a fixed guide block 24 is slidably connected to the surface of the lifting rod 22. The fixed guide block 24 is fixedly installed on one side surface of the handheld lever 1.

[0047] A U-shaped slide 20 is fixedly mounted on one side of the handheld lever 1, providing sliding support and guidance for the lifting rod 22. This ensures the stability of the lifting rod 22 during its up-and-down sliding, preventing displacement and drive failure. The lifting rod 22, slidably connected to the surface of the U-shaped slide 20, extends to the bottom of the handle of the handheld lever 1. The operator can easily lift the lifting rod 22 while holding the handheld lever 1 without changing their grip, ensuring smooth operation. A spring 21 fitted onto the surface of the U-shaped slide 20 automatically resets the lifting rod 22; releasing it after lifting returns the lifting rod 22 to its initial position, preparing for the next seed release. The lifting rod 22 requires manual lifting and reset, improving ease of operation. The wedge 23 fixed to one side of the bottom end of the lifting rod 22 uses the guiding effect of the wedge surface to convert the vertical downward movement of the lifting rod 22 into the horizontal sliding of the U-shaped connecting slide plate 18. The transmission structure is simple and efficient. Moreover, the contact between the wedge 23 and the U-shaped connecting slide plate 18 is a surface contact, which ensures uniform force distribution and reduces wear. The fixed guide block 24 slidably connected to the surface of the lifting rod 22 further enhances the guiding accuracy of the lifting rod 22 during sliding, preventing the lifting rod 22 from tilting or shaking during long-distance sliding, and ensuring precise contact and transmission between the wedge 23 and the U-shaped connecting slide plate 18.

[0048] Furthermore, a guide plate 25 is installed obliquely on one side surface of the hollow inclined support sleeve 10. The guide plate 25 is located below the bottom opening of the seed storage box 16 and is used to guide the discharged seeds into the soil cut formed by the root cutting knife 14.

[0049] The guide plate 25, which is installed at an angle on one side of the hollow inclined support sleeve 10, is located below the bottom opening of the seed storage box 16. It can accurately guide the seeds discharged from the seed storage box 16 into the soil cut formed by the root cutting knife 14, so as to prevent the seeds from scattering outside the cut and causing ineffective planting. It ensures that the seeds of competing plants can germinate and grow in the area where the roots of Artemisia are cut off, and inhibits the sprouting of Artemisia through root competition, thus consolidating the root cutting and eradication effect.

[0050] Working principle: To adjust the cutting depth, rotate the adjusting screw 7 on the fixed block 6 on one side of the hand handle 1. Since the adjusting screw 7 is threadedly connected to the screw block 8 fixed on the outer surface of the adjusting slide rod 3, and the adjusting slide rod 3 is slidably connected in the slide groove 2 at the bottom of the hand handle 1, the rotation of the adjusting screw 7 will drive the adjusting slide rod 3 to slide up and down along the slide groove 2. The up and down displacement of the adjusting slide rod 3 will synchronously change the insertion depth of the ground plug 4, thereby adjusting the overall support height of the device, and finally realizing the adjustable cutting depth of the root cutter 14 into the soil. The bottom end of the adjusting screw 7 is rotatably connected to the fixed block 9 to ensure the stability of the screw rotation process.

[0051] The operator steps on the foot pedal 5 at the bottom of the adjusting slide rod 3, so that the ground plug 4 at the bottom of the adjusting slide rod 3 is inserted into the soil, thus completing the positioning and fixing of the device and preventing the device from shifting during the root cutting operation.

[0052] The hydraulic rod 11, which is hinged to the surface of the hollow inclined support sleeve 10, is activated. The piston end of the hydraulic rod 11 applies a thrust to the connecting sleeve 12. Since the connecting sleeve 12 is rotatably connected to the surface of the hollow inclined support sleeve 10, the connecting sleeve 12 will drive the root cutting blade 14 fixed in the insertion groove 13 on its surface to swing around the rotation axis of the hollow inclined support sleeve 10.

[0053] By controlling the stroke of the hydraulic rod 11, the root cutting knife 14 cuts into the soil at a 45° angle, with the cutting depth kept stable at 10-20 cm. The height of the sliding rod 3 can be adjusted to precisely cut the main root of the grass. At the same time, the protective cover 15 (transparent material) fixed on one side of the handheld rod 1 covers the outside of the root cutting knife 14 to prevent soil debris from flying and ensure the safety of the operation.

[0054] It should be noted that the hydraulic rod 11 is equipped with a stroke regulating valve (not marked). Before operation, the stroke regulating valve can be adjusted to set the maximum extension of the piston end of the hydraulic rod 11 according to the preset root cutting depth of 10-20 cm. The control principle is well known to those in the field and will not be described in detail here.

[0055] After the root cutting operation is completed, the operator lifts the lifting rod 22, which extends to the handle of the hand lever 1 (the lifting rod 22 is slidably connected to the U-shaped slide 20 and the fixed guide block 24, and the U-shaped slide 20 and the fixed guide block 24 are both fixed to one side of the hand lever 1). The wedge block 23 at the bottom of the lifting rod 22 moves upward and contacts the U-shaped connecting slide plate 18 and pushes it to slide (the U-shaped connecting slide plate 18 is slidably connected to the surface of the seed storage box 16, and the seed storage box 16 is installed on one side of the hollow inclined support sleeve 10).

[0056] The sliding of the U-shaped connecting slide plate 18 will cause the baffle 17 at the bottom opening of the seed storage box 16 (the baffle 17 is connected to one end of the U-shaped connecting slide plate 18) to slide to one side. The competing plant seeds pre-stored in the seed storage box 16 will be discharged from the bottom opening. The discharged seeds will fall onto the guide plate 25 installed at an angle on one side of the hollow inclined support sleeve 10. Through the guiding action of the guide plate 25, the seeds will be accurately guided into the soil cut formed by the root cutting knife 14.

[0057] After the lifting rod 22 is released, the spring 21 on the surface of the U-shaped slide 20 drives the lifting rod 22 to reset. At the same time, the reset spring 19 on the parallel section of the U-shaped connecting slide 18 drives the U-shaped connecting slide 18 and the baffle 17 to reset, closing the bottom opening of the seed storage box 16 and completing one operation cycle.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
