Description

Technical Field

[0001] The present invention relates to the technical field of ecological management, and in particular to a device and method for eliminating invasive species. Background Art

[0002] Invasive species are those species that are artificially introduced or naturally spread into new ecosystems and pose a threat to the structure, function or biodiversity of the system. These species often have strong reproductive capacity, adaptability and competitiveness, and can quickly gain a dominant position in the new environment, causing serious damage to the local ecosystem. Therefore, in order to protect biodiversity and maintain ecological balance, it is necessary to eliminate invasive species.

[0003] At present, the eradication technologies for invasive species mainly include physical control and chemical control. Physical control usually includes manual removal, burning and other methods. Although this method is direct and effective, it is labor-intensive, costly, and difficult to implement for invasive species that spread over a large area. Chemical control refers to the use of chemical pesticides such as herbicides to kill invasive species. This method has the advantages of rapid effect and easy use, but it will also kill many local species and cause ecological damage. At the same time, the application of chemical pesticides in special environments such as reservoirs and lakes will also cause environmental pollution. Therefore, in response to the above problems, there is an urgent need for a method for comprehensive control of invasive species. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0026] The present invention discloses a method for eliminating invasive species. The cutting mechanism in the elimination device is used to cut the invasive species and send them into a crushing mechanism for crushing. After crushing, the invasive species are discharged to the ground and sprayed with reagents. 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 reagents. The order of spraying the reagents and digging the roots of the invasive species can be interchanged. In the process of digging the soil, the rotary tillage mechanism mixes the roots of the invasive species and the crushed plants discharged to the ground, and combines with relevant reagents to achieve the purpose of eliminating the invasive species. According to the results after treatment, the elimination rate of the invasive species can reach 70-80%. After multiple treatments using the above method, the elimination rate of the invasive species can reach more than 90%.

[0027] Wherein, the reagent is a bacterial agent that has a fermentation effect on the roots and plants of invasive species, and / or a herbicide that has an inhibitory effect on the activity of the roots of invasive plants, and the invasive plants include Spartina alterniflora, Solidago asiatica or Cyperus rotundus. The reagent can be selected according to the type of invasive plant, and the dosage can be applied according to the guidance dosage. Such as glyphosate, imazapyr, methotrexate, dimethyl tetrachloride sodium salt, etc.

[0028] refer to Figure 1-Figure 5The present invention also discloses an invasive species extermination device. According to the above extermination method, the extermination device disclosed in the present invention is used to implement the corresponding actions of each part. Specifically: the extermination device includes a cutting mechanism, a crushing mechanism, and an interchangeable reagent spraying mechanism and a rotary tillage mechanism 1 which are sequentially arranged on a frame 2. The axes of the cutting mechanism, the crushing mechanism, the spraying mechanism, the rotary tillage mechanism and the dial frame are parallel to each other. The rotary tillage mechanism 1 is a prior art and can be directly installed on the frame.

[0029] Specifically: the cutting mechanism includes a synchronous wheel 3 correspondingly arranged on the frame 2, the axis of the synchronous wheel is arranged vertically, and a synchronous belt 4 is sleeved on the synchronous wheel 3, the belt surface of the synchronous belt 4 is arranged facing the invasive plants, and the synchronous belt and the synchronous wheel are both provided with teeth, and the two are meshed to prevent the synchronous belt from slipping on the synchronous wheel. A plurality of blades 5 are arranged in an array on the belt surface of the synchronous belt 4, that is, the blades are arranged in an aligned manner in the vertical direction, and the blades are arranged in multiple horizontal rows, which can cut plants of a certain height into multiple sections, and the upper part enters the crushing mechanism. Both sides of the blade 5 are blades, and the plants can be cut regardless of whether the synchronous belt rotates clockwise or counterclockwise. At the same time, by setting the blades on the synchronous belt to cut the plants, a larger area or range can be cut at one time, thereby increasing the removal efficiency of the plants; the synchronous wheel 3 is fixed on the frame 2 through a fixing frame 6, and one of the synchronous wheels 3 is driven by a first motor 7. The first motor and the synchronous wheel can be driven by a chain, a gear, a pulley, etc.

[0030] Furthermore, in order to increase the strength of the synchronous belt, a support plate 8 is provided in the area surrounded by the synchronous belt 4 and in contact with the inner ring surface of the synchronous belt 4. Figure 1 As shown, the support plate is arranged vertically, and its width is the same as the width of the synchronous belt, and its two ends are as close to the synchronous wheel as possible. In order to make the support plate realize the tensioning effect, and at the same time, adjust the length of the blade on the synchronous belt facing outward, a transmission cylinder 9 with two ends opened is arranged between the support plates 8, and the transmission cylinder and the support plate are not fixed. The transmission cylinder 9 is arranged in the middle of the support plate 8, and the two support plates 8 are correspondingly provided with adjustment columns 10, and the two adjustment columns 10 extend into the transmission cylinder 9 from the two ends of the transmission cylinder respectively, and are threadedly connected with the transmission cylinder 9; further, in order to drive the transmission cylinder to rotate, the two adjustment columns move toward the outside of the transmission cylinder respectively, so as to adjust the distance between the two support plates 8 by driving the transmission cylinder 9 to rotate, and the thread rotation direction of the part of the transmission cylinder 9 that is threadedly connected with the two adjustment columns 10 is opposite. As one embodiment, the length of the two adjustment columns is the same as the length of the transmission cylinder. When the support plate fits the inner wall of the synchronous belt, the support plate just contacts the two ends of the transmission cylinder, and the synchronous belt is supported by the transmission cylinder and the adjustment column to prevent it from collapsing.

[0031] Furthermore, in order to drive the transmission cylinder to rotate and adjust the distance between the two support plates, a connecting plate 11 is arranged 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 arranged through the connecting plate 11 by means of a bearing 13. A second bevel gear 15 meshing with the first bevel gear 12 is arranged 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, the first bevel gear is driven to drive the transmission cylinder to rotate, so that the two adjusting columns in the transmission cylinder are simultaneously screwed out of the transmission cylinder, thereby increasing the distance between the two support plates.

[0032] Furthermore, in order to increase the stability between the two support plates, telescopic rods 16 are arranged on both sides of the transmission cylinder 9 between the two support plates 8. Further, the fixing frame 6 is in a "C" shape, the vertical plates are correspondingly arranged, 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 arranged in the opening of the fixing frame 6. A through hole 17 is arranged 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 with both ends respectively fixed to the support plate 8 is also arranged 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] Furthermore, in order to stir the cut plants into the crushing mechanism and prevent them from falling completely on the ground, a dial frame 18 for stirring the invasive plants into the crushing mechanism is arranged above the cutting mechanism. The dial frame is a prior art. For example, the dial frame 18 is a polygonal frame structure, such as a pentagon, and is connected through a fixed shaft 28 at the center and is driven by a third motor. A plurality of comb teeth 29 are arranged on the cross bar 30 of the dial 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 dial frame rotates to stir the top part of the plants into the dial frame, and cooperates with the cutting mechanism to make the plants enter the crushing mechanism.

[0034] Furthermore, the crushing mechanism includes a fixed cylinder 19 fixed on the frame 2, the fixed cylinder is closed at both ends and fixed on the frame, a crushing cylinder 20 is coaxially arranged inside the fixed cylinder 19, the crushing cylinder is closed at both ends, crushing teeth 21 are arranged on the outer wall of the crushing cylinder 20, and the crushing teeth are located in the cavity between the fixed cylinder and the crushing cylinder, so as to crush the plants entering the cavity, and the crushing 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 crushing cylinder and extend out of the fixed cylinder, or the rotating shaft can be set through the axis of the crushing cylinder, and its two ends extend out of the crushing cylinder and the fixed cylinder in turn, and it can be set according to actual needs. The rotating shaft can be fixed to the crushing cylinder and the fixed cylinder by bearings. A feed port 24 is provided on the side of the fixed cylinder 19 facing the wheel frame 18, a feed trough 25 is provided at the bottom of the feed port 24, a discharge port 26 is provided on the other side of the fixed cylinder 19 corresponding to the feed port 24, and a discharge trough 27 inclined downward is provided on the discharge port 26. It should be noted that the size and inclination angle of the feed port and the discharge port, the feed trough and the discharge trough can be set as required. The discharge port is provided at a position close to the bottom of the fixed cylinder, and baffles are provided at both ends of the feed trough and the discharge trough. In order to allow the plants to successfully enter the crushing mechanism after being cut, the wheel frame 18 is partially located above the feed trough 25, and the plants discharged from the wheel frame directly fall into the feed trough and slide into the fixed cylinder through the feed trough.

[0035] Furthermore, in order to cut and crush plants of different heights, the wheel frame and the crushing mechanism are arranged to be height-adjustable. Specifically: the frame body 2 is respectively provided with adjustment holes 31 for adjusting the height of the fixed shaft 28 and the rotating shaft 22, and at least two support grooves 32 are vertically arranged on the side walls of the adjustment holes 31. The bottom of the support grooves 32 is arc-shaped, which is used to support and limit 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 wheel frame and the crushing mechanism can be adjusted. The fixing of the fixed shaft and the rotating shaft on the frame body can be fixed by existing technologies, such as fixing a fixing plate on the fixed shaft and the rotating shaft through a bearing sleeve, and then fixing the fixing plate to the frame body with bolts.

[0036] Furthermore, the spraying mechanism includes at least one reagent tube 33 fixed on the frame 2, and the reagent tube 33 is provided with a plurality of nozzles 34 tilted downward, and the frame 2 is provided with a reagent box 35, and the reagent box 35 is connected to the reagent tube 33 through a pipeline, and a reagent pump is provided on the pipeline. It should be noted that: multiple reagent tubes can be arranged in parallel, each reagent tube is connected to a reagent box, and each reagent box can be filled with different reagents. If the same reagent is used, multiple reagent tubes can be connected to one reagent box.

[0037] Furthermore, wheels can be arranged at the bottom of the frame, handrails can be arranged near the rotary tillage mechanism of the frame, and controllers or control switches can be arranged on the handrails to control the opening and closing of various motors and other equipment. For the killing device, the handrails can be used to manually push the device to operate to treat the invasive plants, or an electric cart with a seat can be connected to the frame to drive the entire device to operate. The specific settings can be made according to the needs.

[0038] When using the present invention, it is only necessary to adjust the height of the wheel frame and the crushing mechanism according to the height of the invasive plants, and add appropriate reagents into the reagent box according to the type of the invasive plants. Then, the frame is driven to move, and the invasive species are removed by starting the cutting mechanism, the wheel frame, the crushing mechanism, the spraying mechanism and the rotary tillage mechanism. The timing and duration of opening and closing of these mechanisms can be flexibly controlled manually.
