Description

Technical Field

[0001] This invention relates to the field of ecological governance technology, specifically to an invasive species eradication device and method. Background Technology

[0002] Invasive species are those introduced by humans or spread naturally into new ecosystems and pose a threat to the structure, function, or biodiversity of those ecosystems. These species often possess strong reproductive capabilities, adaptability, and competitiveness, enabling them to quickly gain dominance in new environments and cause severe damage to local ecosystems. Therefore, it is necessary to remove invasive species in order to protect biodiversity and maintain ecological balance.

[0003] Currently, the main technologies for controlling invasive species include physical control and chemical control. Physical control typically involves methods such as manual removal and burning. While this method is direct and effective, it is labor-intensive, costly, and difficult to implement for invasive species that have spread over a large area. Chemical control involves using herbicides and other chemical pesticides to kill invasive species. This method has advantages such as rapid effect and ease of use, but it also kills many native species, causing ecological damage. Furthermore, the application of chemical pesticides in special environments such as reservoirs and lakes can cause environmental pollution. Therefore, a comprehensive approach to the management of invasive species is urgently needed to address these issues. Summary of the Invention

[0024] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.

[0026] This invention discloses a method for eradicating invasive species. The method employs a cutting mechanism in a removal device to cut off the invasive species and feed it into a pulverizing mechanism for crushing. After crushing, the pulverized species is discharged onto the ground and sprayed with a reagent. Then, a rotary tillage mechanism 1 is used to dig out the roots of the invasive species and mix them with the crushed invasive species and reagent. The order of spraying the reagent and digging out the roots of the invasive species can be reversed. During the soil digging process, the rotary tillage mechanism mixes the roots of the invasive species with the crushed plant material discharged onto the ground, combined with the relevant reagent, to achieve the purpose of eradicating the invasive species. According to the results, the eradication rate of invasive species can reach 70-80%. After multiple treatments using the above method, the eradication rate of invasive species can reach over 90%.

[0027] The reagent is a microbial agent that ferments the roots and plants of invasive species, and / or a herbicide that inhibits the activity of the roots of invasive plants, including Spartina alterniflora, Solidago virgaurea, or Cyperus rotundus. The reagent should be selected based on the type of invasive plant, and the dosage should be applied according to the guidelines. Examples include glyphosate, imidacloprid, spartrazan, and sodium 2,4-D.

[0028] refer to Figures 1-5This invention also discloses an invasive species eradication device. Based on the aforementioned eradication method, the eradication device disclosed in this invention is used to achieve the corresponding actions of each part. Specifically, the eradication device includes a cutting mechanism, a crushing mechanism, and interchangeable reagent spraying and rotary tillage mechanisms 1, all arranged sequentially on the frame 2. The shafts on the cutting mechanism, crushing mechanism, spraying mechanism, rotary tillage mechanism, and the rotary wheel frame are all parallel to each other. The rotary tillage mechanism 1 is existing technology and can be directly installed on the frame.

[0029] Specifically: The cutting mechanism includes a synchronous wheel 3 correspondingly mounted on the frame 2, with the axis of the synchronous wheel vertically positioned. A synchronous belt 4 is fitted onto the synchronous wheel 3, with the belt surface of the synchronous belt 4 facing the invading plant. Both the synchronous belt and the synchronous wheel are equipped with teeth, which mesh to prevent the synchronous belt from slipping on the synchronous wheel. Several blades 5 are arrayed on the surface of the synchronous belt 4, i.e., the blades are aligned vertically, arranged in multiple horizontal rows, capable of cutting plants of a certain height into multiple segments, with the upper part entering the crushing mechanism. Both sides of the blades 5 are cutting edges, allowing for cutting of plants regardless of whether the synchronous belt rotates clockwise or counterclockwise. Furthermore, by using blades on the synchronous belt, a larger area or range can be cut at once, increasing the efficiency of plant removal. The synchronous wheel 3 is fixed to the frame 2 by a fixing bracket 6, and one of the synchronous wheels 3 is driven by a first motor 7. The first motor and the synchronous wheel can be transmitted through chains, gears, pulleys, etc.

[0030] Furthermore, to increase the strength of the synchronous belt, a support plate 8 is provided within the area enclosed by the synchronous belt 4, corresponding to the surface of the inner ring of the synchronous belt 4, such as... Figure 1 As shown, the support plate is vertically arranged, with its width matching that of the synchronous belt, and its ends are positioned as close as possible to the synchronous pulley. To achieve tension on the support plate, and to adjust the outward-facing length of the blades on the synchronous belt, a transmission cylinder 9 with open ends is positioned between the support plates 8. The transmission cylinder is not fixed to the support plates, and is located in the middle of the support plates 8. Adjusting posts 10 are correspondingly positioned on the two support plates 8, extending from both ends of the transmission cylinder into the transmission cylinder 9 and threadedly connected to it. Furthermore, to allow the two adjusting posts to move outward during the rotation of the transmission cylinder, the distance between the two support plates 8 is adjusted by driving the transmission cylinder 9 to rotate. The threads of the portions of the transmission cylinder 9 threadedly connected to the two adjusting posts 10 have opposite directions. In one embodiment, the lengths of the two adjusting posts are the same as the length of the transmission cylinder. When the support plate is in contact with the inner wall of the synchronous belt, it contacts both ends of the transmission cylinder, supporting the synchronous belt through the transmission cylinder and adjusting posts to prevent it from collapsing.

[0031] Further, in order to drive the transmission cylinder to rotate so as to adjust the distance between the two support plates, a connecting plate 11 is provided between the two fixing frames 6. A first bevel gear 12 is sleeved and fixed on the transmission cylinder 9. A rotating rod 14 is disposed through the connecting plate 11 via a bearing 13. A second bevel gear 15 meshing with the first bevel gear 12 is provided at one end of the rotating rod 14 passing through the connecting plate 11. By rotating the rotating rod to drive the second bevel gear to rotate, and further drive the first bevel gear to drive the transmission cylinder to rotate, so that the two adjusting columns in the transmission cylinder simultaneously screw out of the transmission cylinder, thereby increasing the distance between the two support plates.

[0032] Further, in order to increase the stability between the two support plates, telescopic rods 16 are provided on both sides of the transmission cylinder 9 between the two support plates 8. Further, the fixing frame 6 is in a "U" shape, with the vertical plates corresponding to each other. The connecting plates are respectively fixed on the vertical plates of the fixing frame and are perpendicular to the support plates for supporting the rotating rod. The synchronous pulley 3 is rotatably disposed in the opening of the fixing frame 6. A through hole 17 is disposed through the vertical plate of the fixing frame 6. The center line of the through hole is the same as and parallel to the axis direction of the synchronous pulley. The telescopic rod 16 whose two ends are respectively fixed to the support plate 8 is also disposed in the through hole 17. The telescopic rod can be a sleeve-type telescopic rod, a hydraulic rod, a telescopic rod with a spring, etc., which can be set according to needs, and can increase the stability of the support plate to a certain extent.

[0033] Further, in order to stir the cut plants into the pulverizing mechanism and prevent them from falling completely on the ground, a paddle wheel frame 18 for stirring the invasive plants into the pulverizing mechanism is provided above the cutting mechanism. The paddle wheel frame is a prior art, for example: the paddle wheel frame 18 is a polygonal frame structure, such as a pentagon, which is connected through a fixed shaft 28 at the center and is driven by a third motor. A plurality of comb teeth 29 are provided on the cross bar 30 of the paddle wheel frame 18. The comb teeth 29 are inclined downward outward and the orientations of the comb teeth 29 on each cross bar 30 are the same. During the process of cutting plants, the paddle wheel frame rotates to stir the top part of the plants into the paddle wheel frame and cooperate with the cutting mechanism to make the plants enter the pulverizing mechanism.

[0034] Furthermore, the pulverizing mechanism includes a fixed cylinder 19 fixed to the frame 2. The fixed cylinder is closed at both ends and fixed to the frame. A pulverizing cylinder 20 is coaxially arranged inside the fixed cylinder 19. The pulverizing cylinder is also closed at both ends. Pulverizing teeth 21 are provided on the outer wall of the pulverizing cylinder 20. The pulverizing teeth are located in the cavity between the fixed cylinder and the pulverizing cylinder, thereby pulverizing the plants that enter the cavity. The pulverizing cylinder 20 is fixed to the frame 2 by a rotating shaft 22 and driven by a second motor 23. That is, the rotating shaft passes through the outside of the fixed cylinder and is connected to the second motor. The rotating shaft can be fixed at both ends of the pulverizing cylinder and extend outside the fixed cylinder, or it can be installed through the axis of the pulverizing cylinder, with its two ends extending out of the pulverizing cylinder and the fixed cylinder in sequence. The specific configuration can be determined according to actual needs. The rotating shaft can be fixed to the pulverizing cylinder and the fixed cylinder by bearings. The fixed cylinder 19 has a feed inlet 24 on the side facing the feed wheel frame 18, and a feed trough 25 at the bottom of the feed inlet 24. The fixed cylinder 19 has a discharge outlet 26 on the other side corresponding to the feed inlet 24, and a downward-sloping discharge trough 27 on the discharge outlet 26. It should be noted that the size and angle of the feed inlet and outlet, and the feed trough and discharge trough, can be set as needed. The discharge outlet is located near the bottom of the fixed cylinder, and baffles are provided at both ends of the feed trough and discharge trough. To ensure that the cut plants successfully enter the crushing mechanism, the feed wheel frame 18 is partially located above the feed trough 25. Plants discharged from the feed wheel frame fall directly into the feed trough and slide into the fixed cylinder.

[0035] Furthermore, to cut and shred plants of different heights, the dial frame and shredding mechanism are height-adjustable. Specifically, the frame 2 is vertically provided with adjustment holes 31 for adjusting the height of the fixed shaft 28 and the rotating shaft 22. At least two support grooves 32 are vertically provided on the side wall of each adjustment hole 31. The bottom of each support groove 32 is arc-shaped and used to support and restrict the fixed shaft and the rotating shaft. By placing the fixed shaft and the rotating shaft in support grooves of different heights, the height of the dial frame and the shredding mechanism can be adjusted. The fixed shaft and the rotating shaft are fixed to the frame using existing technology, such as fixing a fixing plate to the fixed shaft and the rotating shaft using bearing sleeves, and then bolting the fixing plate to the frame.

[0036] Furthermore, the spraying mechanism includes at least one reagent tube 33 fixed to the frame 2. The reagent tube 33 is equipped with several downward-sloping nozzles 34. A reagent box 35 is mounted on the frame 2, and the reagent box 35 is connected to the reagent tube 33 via a pipe. A reagent pump is mounted on the pipe. It should be noted that multiple reagent tubes can be arranged side-by-side, each connected to a reagent box. Each reagent box can contain different reagents. If the same reagent is used, multiple reagent tubes can be connected to one reagent box.

[0037] Furthermore, wheels can be installed at the bottom of the frame, and a handrail can be installed near the rotary tillage mechanism. A controller or control switch can be installed on the handrail to control the operation of various motors and other equipment. For the eradication device, it can be manually pushed using the handrail to treat invasive plants. Alternatively, an electric trolley with a seat can be connected to the frame to drive the entire device; the specific configuration can be adjusted according to needs.

[0038] When using this invention, simply adjust the height of the rotating wheel frame and the crushing mechanism according to the height of the invasive plant, and add appropriate reagents to the reagent tank according to the type of invasive plant. Then, drive the frame to move, and remove the invasive species by activating the cutting mechanism, rotating wheel frame, crushing mechanism, spraying mechanism, and rotary tillage mechanism. The timing and duration of the activation and deactivation of these mechanisms can be flexibly controlled manually.
