Description

Technical Field

[0001] This invention belongs to the technical field of plant eradication devices, specifically relating to a fine-grained device for the eradication of invasive plants between plants. Background Technology

[0002] For large-scale invasive plants, chemical control methods such as pesticide spraying or physical control methods such as burning or specialized pest control machinery can be used. However, for a small number of individual invasive plants between crop plants, these methods are not suitable for precise control, and may easily damage crops and affect their growth. Therefore, how to eliminate invasive plants between crop plants is a technical problem that needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a device for the precise elimination of invasive plants between plants, which has a transfer component to facilitate the transfer of food between different chambers.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: This application provides a device for the precise eradication of invasive plants between plants, including an insertion channel, multiple cutting cables, and an isolation channel. The insertion channel has a spiral groove on its peripheral wall, with an opening on the side of the spiral groove near the axis of the insertion channel. The beginning and end of the spiral groove are arranged radially opposite to each other along the insertion channel, with the end of the spiral groove located above the beginning. Multiple cutting cables pass through the spiral groove, with the ends of the multiple cutting cables at the beginning of the spiral groove connected to the insertion channel. The ends of the multiple cutting cables at the beginning of the spiral groove are spaced apart circumferentially along the insertion channel. The insertion channel surrounds the outer peripheral wall of the isolation channel.

[0005] In some embodiments, the insertion channel is rotatably provided with a winding wheel, and the inner wall of the first end of the spiral groove is provided with multiple wire holes corresponding to multiple cutting steel cables. The wire holes penetrate the peripheral wall of the insertion channel and are spaced apart along the circumference of the insertion channel. The cutting steel cables pass through the wire holes and are wound around the winding wheel.

[0006] In some embodiments, a protective channel is also included, which is sleeved on the outer peripheral wall of the insertion channel. The protective channel and the inner peripheral wall of the insertion channel are spaced apart. The protective channel is provided with a connecting through hole, and the end of the cutting steel cable near the end of the spiral groove is disposed outside the protective channel through the connecting through hole.

[0007] In some embodiments, the inner peripheral wall of the insertion channel is provided with a spiral shielding strip, the spiral shielding strip is made of a flexible material, the spiral shielding strip extends along a spiral groove, the spiral shielding strip covers the opening, and the top of the spiral shielding strip is connected to the top of the opening.

[0008] In some embodiments, a reset recess is provided at the beginning of the spiral groove, the spiral groove is connected to the reset recess, and the wire hole is provided in the reset recess.

[0009] In some embodiments, the cross-section of the spiral groove is not perfectly circular, the opening of the spiral groove is smaller than the interior of the spiral groove, and a limiting component is provided at the end of the cutting cable near the end of the spiral groove. The limiting component includes a main body, an annular sleeve, and multiple deformable arms. The main body is connected to the end of the cutting cable, the annular sleeve is fitted onto the cutting cable, and the multiple deformable arms are circumferentially spaced around the main body. Each deformable arm includes two rotatably connected arm portions, one of which is rotatably connected to the main body, and the other is rotatably connected to the annular sleeve. Elastic elements are respectively provided between the arm portion and the main body, between the arm portion and the annular sleeve, and between the two arms.

[0010] In some embodiments, along the extending direction of the spiral groove, a plurality of partition plates are spaced apart inside the spiral groove, and the partition plates are provided with closing through holes.

[0011] In some embodiments, a pulling component is also included, wherein the ends of a plurality of cutting cables near the end of the spiral groove are detachably connected to the pulling component.

[0012] In some embodiments, the pulling component includes a housing and a plurality of limiting plates. The housing has an inlet and an outlet, and includes a sidewall with a plurality of insertion holes spaced apart from the limiting plates. The limiting plates are inserted into the insertion holes and have notched slots that extend to the edge of the limiting plates. The limiting component is configured to be unable to pass through the notched slots.

[0013] In some embodiments, one end of the housing is larger than the other, and the inlet and outlet of the housing are located at the smaller end of the housing.

[0014] The present invention has the following beneficial effects:

[0015] 1. By placing the invasive plants within the insertion channel, this device can precisely eliminate the invasive plants between crop plants, reducing the risk of damage to crops during the elimination of invasive plants.

[0016] 2. Once the spiral groove is opened, multiple cutting cables are pulled, allowing them to cut the roots of invasive plants and eradicate them. Cutting plants with these cables offers several advantages: firstly, the cutting resistance is low, making it easier to sever the roots; secondly, it reduces the risk of damage from stones in the soil. Conventional cutting tools struggle to avoid stones, easily damaging the blades, while the slender, deformable structure of the cutting cables allows them to slide past stones.

[0017] 3. Since the cutting steel cables are spaced apart along the circumference of the insertion channel at the beginning of the spiral groove, multiple cutting steel cables can form an isolation net when the cutting steel cables are taut. This allows the stems and leaves above the roots of the invading plant to be pulled out along with the insertion channel when it is pulled out of the ground.

[0018] 4. The advantage of the isolation net formed by cutting steel cables is that when lifting invasive plants, soil can leak through the gaps in the cut steel cables, reducing the burden on the lifting and installation channels. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0034] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0035] This application provides a device for the precise eradication of invasive plants between plants, including an insertion channel 1, multiple cutting cables 8, and an isolation channel 3. The insertion channel 1 has a spiral groove 6 on its peripheral wall, with an opening on the side of the spiral groove 6 near its axis. The beginning and end of the spiral groove 6 are radially opposite to each other along the insertion channel 1, with the end of the spiral groove 6 located above the beginning. Multiple cutting cables 8 pass through the spiral groove 6, with the ends of the multiple cutting cables 8 at the beginning of the spiral groove 6 connected to the insertion channel 1. The ends of the multiple cutting cables 8 at the beginning of the spiral groove 6 are spaced apart circumferentially along the insertion channel 1. The insertion channel 1 surrounds the outer peripheral wall of the isolation channel 3.

[0036] Insertion channel 1 is used for insertion into the ground. Specifically, in use, insertion channel 1 is aligned with the invading plant between crop plants, so that when insertion channel 1 is inserted into the ground, the invading plant is inside insertion channel 1.

[0037] When the insertion channel 1 is inserted into the ground, the spiral groove 6 is also inserted into the ground at least in the area near the beginning, ensuring that the cutting cable 8 can cut the invasive plants.

[0038] The fact that the beginning and end of the spiral groove 6 are arranged radially opposite each other along the insertion channel 1 means that, in the horizontal direction, the beginning and end of the spiral groove 6 are arranged opposite each other, but in the vertical direction, the beginnings of the spiral groove 6 are one higher and the end lower. This ensures that the spiral groove 6 can at least complete one revolution around the spiral groove 6.

[0039] The opening of the spiral groove 6 allows the cutting cable 8 to enter the spiral groove 6.

[0040] The insertion channel 1 is arranged around the outer peripheral wall of the isolation channel 3, allowing the isolation channel 3 to move axially along the insertion channel 1. This enables the isolation channel 3 to either close or open the opening of the spiral groove 6. Specifically, during the insertion of the insertion channel 1 into the ground, the isolation channel 3 closes the opening of the spiral groove 6 to prevent soil from entering. After the insertion of the insertion channel 1 is complete, the spiral groove 6 moves upward, allowing the opening to be opened.

[0041] The insertion channel 1 may be equipped with a locking structure to unlock or lock the isolation channel 3. When unlocked, the isolation channel 3 can move relative to the insertion channel 1; conversely, when locked, the isolation channel 3 is fixed relative to the insertion channel 1. The locking structure used here is a mature design found in existing technologies; any suitable type can be selected, and therefore will not be elaborated further.

[0042] Once the opening of the spiral groove 6 is opened, multiple cutting cables 8 are pulled, enabling them to cut the roots of the invasive plant and thus eradicate it. After cutting, appropriate chemical agents can be added to the insertion channel 1 as needed to assist in eradication, prevent the invasive plant from regrowing, improve the eradication effect, and reduce the risk of chemical agents affecting crops due to the isolation provided by the insertion channel 1.

[0043] Cutting plants using the cutting cable 8 offers several advantages. First, it reduces cutting resistance, making it easier to sever the roots of invading plants. Second, it lowers the risk of damage to the cutting cable 8 from rocks in the soil. Conventional cutting tools struggle to avoid rocks, leading to tool damage, while the slender and deformable structure of the cutting cable 8 allows it to glide past rocks. Furthermore, the circular cutting motion of the cutting cable 8 enhances the cutting effect.

[0044] Since the cutting steel cables 8 are spaced apart along the circumference of the insertion channel 1 at the beginning of the spiral groove 6, multiple cutting steel cables 8 can form an isolation net when the cutting steel cables 8 are taut. This allows the stems and leaves above the roots of the invading plant to be pulled out along with the insertion channel 1 when it is pulled out of the ground.

[0045] The advantage of the isolation net formed by cutting the steel cable 8 is that when lifting invasive plants, soil can leak through the gaps in the cutting steel cable 8, reducing the burden on the lifting and installation channel 1.

[0046] In some embodiments, the insertion channel 1 is rotatably provided with a winding wheel 7, and the inner wall of the first end of the spiral groove 6 is provided with a plurality of wire holes 10 corresponding to a plurality of cutting steel cables 8. The wire holes 10 penetrate the peripheral wall of the insertion channel 1 and are spaced apart along the circumference of the insertion channel 1. The cutting steel cables 8 pass through the wire holes 10 and are wound around the winding wheel 7.

[0047] The drive structure of the winding wheel 7 can be selected from existing structures. For example, the winding wheel 7 can be manually driven, and a locking structure can also be provided at the winding wheel 7 to unlock or lock it. When locked, the winding wheel 7 cannot rotate; when unlocked, the winding wheel 7 can rotate. The locking structure here has mature designs in the prior art; any suitable type can be selected, and therefore will not be described in detail.

[0048] The winding wheel 7 is used to fix and reset the cutting cable 8. That is, when the winding wheel 7 is locked, the cutting cable 8 is fixed to the insertion channel 1, so that the roots of the invasive plant can be cut through the cutting cable 8. After cutting, the insertion channel 1 is pulled out from the ground, and the stems, leaves and soil of the invasive plant inside the insertion channel 1 are cleaned. Then the winding wheel 7 is unlocked, and the winding wheel 7 winds up the cutting cable 8 so that the end of the cutting cable 8 near the end of the spiral groove 6 can be pulled to the beginning of the spiral groove 6. Then the opening is closed by the isolation channel 3, and the cutting cable 8 is unwound. The cutting cable 8 is pushed to move along the spiral groove 6 so that the cutting cable 8 can pass through the end of the spiral groove 6.

[0049] In order to facilitate the movement of the cutting cable 8 along the spiral groove 6, the wire hole 10 can be tilted so that when the winding wheel 7 unwinds the cutting cable 8, the cutting cable 8 moves into the spiral groove 6.

[0050] In some embodiments, a protective channel 2 is also included. The protective channel 2 is sleeved on the outer peripheral wall of the insertion channel 1. The protective channel 2 and the inner peripheral wall of the insertion channel 1 are spaced apart. The protective channel 2 is provided with a connecting through hole. The end of the cutting steel cable 8 near the end of the spiral groove 6 is disposed outside the protective channel 2 through the connecting through hole.

[0051] The gap between the protection channel 2 and the insertion channel 1 can be used to install the winding wheel 7. The protection channel 2 can protect the winding wheel 7, so that when the insertion channel 1 is inserted into the ground, the soil will not come into contact with the winding wheel 7.

[0052] The connecting through hole of the protection channel 2 is used for the cutting steel cable 8 to pass through the connecting through hole, so that the cutting steel cable 8 can be pulled from outside the protection channel 2.

[0053] A switch door 4 can be installed on the protection channel 2, allowing the operator to operate the winding wheel 7 by opening the switch door 4.

[0054] In some embodiments, the inner peripheral wall of the insertion channel 1 is provided with a spiral shielding strip 9, the spiral shielding strip 9 is made of a flexible material, the spiral shielding strip 9 extends along the spiral groove 6, the spiral shielding strip 9 covers the opening, and the top of the spiral shielding strip 9 is connected to the top of the opening.

[0055] For example, the spiral shielding strip 9 can be made of rubber.

[0056] The top of the spiral shielding strip 9 is connected to the top of the opening, so that the bottom of the spiral shielding strip 9 can remain covering the opening when no force is applied. When the cutting cable 8 is removed from the spiral groove 6, the cutting cable 8 can be removed from the bottom of the spiral shielding strip 9 from the spiral groove 6.

[0057] The spiral shielding strip 9 can shield the opening, which can reduce the risk of soil entering the spiral groove 6 when the cutting cable 8 is removed from the spiral groove 6 after the isolation channel 3 is removed from the opening.

[0058] In some embodiments, the first end of the spiral groove 6 is provided with a reset recess 11, the spiral groove 6 is connected to the reset recess 11, and the wire hole 10 is provided in the reset recess 11.

[0059] When the winding wheel 7 pulls the cutting cable 8 to reset, the end of the cutting cable 8 near the end of the spiral groove 6 enters the reset recess 11. This ensures that when the winding wheel 7 winds up the cutting cable 8, the cutting cable 8 will not come into contact with the spiral blocking strip 9, reducing the risk that the cutting cable 8 will pull the spiral blocking strip 9 into the spiral groove 6, causing the spiral blocking strip 9 to fail to cover the opening.

[0060] In some embodiments, the cross-section of the spiral groove 6 is not perfectly circular, the opening of the spiral groove 6 is smaller than the interior of the spiral groove 6, and a limiting component 17 is provided at the end of the cutting cable 8 near the end of the spiral groove 6. The limiting component 17 includes a main body 14, an annular sleeve 16, and multiple deformable arms. The main body 14 is connected to the end of the cutting cable 8, the annular sleeve 16 is sleeved on the cutting cable 8, and the multiple deformable arms are arranged circumferentially around the main body 14. Each deformable arm includes two rotatably connected arm portions 15, one of which is rotatably connected to the main body 14, and the other is rotatably connected to the annular sleeve 16. Elastic elements are respectively provided between the arm portion 15 and the main body 14, between the arm portion 15 and the annular sleeve 16, and between the two arms 15.

[0061] The fact that the cross-section of the spiral groove 6 is not perfectly circular means that there is a gap in the cross-sectional profile of the spiral groove 6, and the opening of the spiral groove 6 is formed at the gap.

[0062] The opening of the spiral groove 6 is smaller than its interior, meaning that the length of the notch in the cross-sectional profile of the spiral groove 6 is smaller than the diameter of the cross-sectional profile of the spiral groove 6. This prevents the limiting component 17 from disengaging from the spiral groove 6.

[0063] The main body 14 is connected to the cutting steel cable 8, so that the cutting steel cable 8 can move together with the limiting component 17.

[0064] The elastic element is used to provide the elastic force that returns the two arms 15 to their original position.

[0065] When the annular sleeve 16 moves away from the main body 14, the included angle between the two arms 15 can increase, thus allowing the two arms 15 to deform.

[0066] The bends of the two arms 15 are used to abut against the inner wall of the spiral groove 6.

[0067] The two arms 15 are bent to form a deformable structure, allowing the connection between the two arms 15 to abut against the inner wall of the spiral groove 6. This increases the stability of the limiting component 17 as it moves along the spiral groove 6, enabling the limiting component 17 to guide the cutting cable 8 along the spiral groove 6. The space between adjacent deformable arms can accommodate the cutting cable 8, allowing the limiting component 17 of one cutting cable 8 to limit the movement of the other cutting cable 8.

[0068] In some embodiments, along the extending direction of the spiral groove 6, a plurality of partition plates 12 are spaced apart inside the spiral groove 6, and the partition plates 12 are provided with closing through holes 13.

[0069] When the limiting component 17 passes the isolation plate 12, the main body 14 of the limiting component 17 first inserts into the closing through hole 13, and then the arm 15 is squeezed towards the cutting steel cable 8, and the limiting component 17 closes, so that the limiting component 17 can pass through the closing through hole 13. After the limiting component 17 passes through the closing through hole 13, under the action of the elastic element, the two arms 15 return to their original positions. When the arms 15 return to their original positions, the bends of the two arms 15 can strike the spiral shielding strip 9, and the spiral shielding strip 9 opens (at this time, the isolation channel 3 can be moved to partially open the opening of the spiral groove 6, so that the bottom of the spiral shielding strip 9 can be opened to discharge the soil). This allows the soil that entered the spiral groove 6 in the previous process to be discharged.

[0070] To improve the soil removal effect, the lower edge of the opening of the spiral groove 6 can be a downward sloping surface.

[0071] When the limiting component 17 moves along the spiral groove 6, it can scrape some of the soil, loosening it and causing it to converge towards the opening side of the spiral groove 6 for easy discharge. Although the scraping area of ​​a single limiting component 17 is limited, multiple cutting cables 8 are provided, so multiple limiting components 17 are also provided, effectively increasing the scraping area.

[0072] Because the threading holes 10 are spaced apart circumferentially along the insertion channel 1, the ends of multiple cutting steel cables 8 are arranged sequentially near the end of the spiral groove 6, meaning that the limiting components 17 of the multiple cutting steel cables 8 are also arranged sequentially in the spiral groove 6. The multiple limiting components 17 pass through the closing through hole 13 in sequence, allowing for multiple discharges of soil and increasing the cleaning effect.

[0073] Furthermore, the multiple limiting components 17 are arranged in sequence, which can increase the limiting effect on the cutting steel cable 8.

[0074] The limiting component 17 can also prevent the risk of the cutting cable 8 coming off the spiral groove 6 when the winding wheel 7 winds the cutting cable 8.

[0075] It should be noted that, in order to avoid obstructing the cutting cable 8 from moving out of the spiral groove 6, the closing through hole 13 has a notched structure, and the size of the notch can be set as needed.

[0076] In some embodiments, a pulling member 5 is also included, wherein the ends of the plurality of cutting cables 8 near the end of the spiral groove 6 are detachably connected to the pulling member 5.

[0077] The cutting cable 8 can be easily pulled by the pulling component 5. The cutting cable 8 is detachably connected to the pulling component 5. When winding the cutting cable 8, the cutting cable 8 and the pulling component 5 can be disconnected, so that the cutting cable 8 can enter the insertion channel 1.

[0078] In some embodiments, the pulling member 5 includes a housing 19 and a plurality of limiting plates 20. The housing 19 is provided with an inlet and an outlet, and includes a sidewall. The sidewall is provided with a plurality of insertion holes at intervals corresponding to the limiting plates 20. The limiting plates 20 are inserted into the insertion holes. The limiting plates 20 are provided with notches and grooves 18, which extend to the edge of the limiting plates 20. The limiting member 17 is configured to be unable to pass through the notches and grooves 18.

[0079] The inlet and outlet are used to insert the limiting component 17 into the housing 19.

[0080] After the limiting component 17 is inserted into the housing 19, the limiting plate 20 is inserted into the insertion hole. The steel cable can enter the notch through groove 18 from the edge of the limiting plate 20. The limiting plate 20 is set behind the limiting component 17 so that when force is applied to the housing 19, the limiting component 17 abuts against the limiting plate 20 and the limiting component 17 cannot be removed from the housing 19.

[0081] Since multiple limiting components 17 are arranged sequentially, after the multiple limiting components 17 are inserted into the housing 19, they are spaced apart along the axial direction of the inlet and outlet, and multiple limiting plates 20 can sequentially limit each limiting component 17.

[0082] When resetting the cutting cable 8, the inlet and outlet can be placed against the end of the spiral groove 6, and then the limiting plate 20 can be pulled out. At this time, the winding wheel 7 will wind up the cutting cable 8, and the limiting component 17 can be pulled out of the housing 19.

[0083] Another advantage of fixing the limiting component 17 with the limiting plate 20 is that, by setting the position of the insertion hole, it is easy to control the cutting timing of multiple cutting cables 8, reducing cutting resistance and increasing cutting effect. For example, it can be set so that the longest cutting cable 8, starting from the first end of the spiral groove 6, cuts first, that is, this cutting cable 8 cuts the root of the invasive plant. After this cutting cable 8 cuts into the invasive plant, the other cutting cables 8 cut into the invasive plant in sequence, from longest to shortest. Multiple cuts can ensure that the invasive plant is completely cut off, and sequential cutting can reduce cutting resistance compared to multiple cutting cables 8 cutting simultaneously. At the same time, if the first cutting cable breaks, the other cutting cables 8 can cut into the invasive plant from the cut formed by the previous cutting cable 8, and continue to cut the invasive plant, ensuring that the invasive plant is cut off and reducing the risk of other cutting cables 8 breaking. Furthermore, it can be set up so that two or three cutting cables 8 start cutting simultaneously, and the other cutting cables 8 then cut in sequence; or one cutting cable 8 cuts first to form an incision, and then the other cables cut simultaneously, so that the incision can expand and promote the breaking of the roots of the invading plant, etc.

[0084] In some embodiments, one end of the housing 19 is larger than the other, and the inlet and outlet of the housing 19 are located at the smaller end of the housing 19.

[0085] The structure of the housing 19, which is larger at one end and smaller at the other, serves two purposes. First, it makes the housing 19 smaller, saving costs and making it easier to handle. Second, the larger end of the housing 19 provides space for the movement of the limiting components 17. This allows multiple limiting components 17 to be spaced apart in the direction perpendicular to the inlet and outlet axis. When the cutting cable 8 is taut, the limiting components 17 abut against the limiting plate 20, making it difficult for the limiting components 17 to move relative to the limiting plate 20. This allows the ends of the cutting cable 8 at the end of the spiral groove 6 to be spaced apart, increasing the surface area of ​​the isolation net formed by the cutting cable 8.

[0086] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
