Abstract
Description
Technical Field
[0001] This utility model belongs to the field of Mikania micrantha control technology, and in particular relates to an eradication device for controlling Mikania micrantha. Background Technology
[0002] Mikania micrantha is an invasive climbing plant native to South America. Due to its exceptional reproductive capacity and rapid growth, it is known as a "plant killer" or "green cancer." It can reproduce asexually through stem nodes, taking root and forming new plants upon contact with soil. It can also spread long distances by wind, producing tens of thousands of tiny seeds per plant. Under suitable conditions, Mikania micrantha can grow up to 20 centimeters per day, quickly covering large areas. By climbing and twining around other plants, it competes for sunlight and inhibits photosynthesis, causing the epiphytic trees, shrubs, and even crops to suffocate and wither. This severely damages native plant diversity and the balance of the ecosystem. Therefore, when it is necessary to eradicate Mikania micrantha, a specialized eradication device is required.
[0003] Existing eradication devices for Mikania micrantha control still have some problems during use. For example, most devices require multiple separate power sources to drive the eradication device to turn the soil and stir the pesticide solution, which not only increases the complexity and manufacturing cost of the equipment, but also leads to unnecessary energy waste. In addition, most devices use fixed nozzles to spray the pesticide, which limits the coverage of the pesticide solution and thus affects the eradication effect.
[0004] Therefore, we provide an eradication device for the control of Mikania micrantha to solve the problems mentioned above. Summary of the Invention
[0005] The purpose of this utility model is to provide a root control device for Mikania micrantha, which can use a separate power source to drive the soil turning device and the mixing device, and can also make the nozzle swing to increase the spraying range. This solves the problem that existing root control devices for Mikania micrantha require multiple power sources to provide power during operation, and most of the nozzles are fixed, which easily leads to a limited spraying range.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to an eradication device for controlling Mikania micrantha, comprising an installation plate, a support plate fixedly connected to one side of the installation plate, a drive motor fixedly connected to one side of the support plate, a drive rod fixedly connected to the output end of the drive motor, a soil-turning roller fixedly connected to the surface of the drive rod, a box fixedly connected to one side of the top of the installation plate, a stirring rod rotatably connected inside the box, a stirring blade fixedly connected to the surface of the stirring rod, a vertical plate fixedly connected to the top of the box, a reciprocating screw rotatably connected to one side of the vertical plate, a threaded sleeve threadedly connected to the surface of the reciprocating screw, a movable rod fixedly connected to the bottom of the threaded sleeve, a rotating rod rotatably connected to the other side of the top of the support plate, a movable plate fixedly connected to the top of the rotating rod, a spray head fixedly connected to one side of the top of the movable plate, the bottom of the movable rod movably connected to the inside of the movable plate, a high-pressure water pump connected to one side of the box via a connecting pipe, a flexible hose connected to the top of the high-pressure water pump, one end of the flexible hose connected to one side of the spray head.
[0008] The present invention is further configured such that a first pulley is fixedly connected to one side of the surface of the transmission rod, a second pulley is fixedly connected to one side of the surface of the stirring rod, a third pulley is fixedly connected to the other side of the surface of the stirring rod, and a fourth pulley is fixedly connected to one side of the surface of the reciprocating screw.
[0009] The present invention is further configured such that the top of the box is connected to a liquid inlet, and a box cover is provided on the top of the liquid inlet.
[0010] The present invention is further configured such that a limiting rod is fixed on one side of the vertical plate, and a connecting plate is fixedly connected to one side of the threaded sleeve, with the connecting plate slidably connected to the surface of the limiting rod.
[0011] The present invention is further configured such that a movable groove is provided inside the movable plate, and the movable rod is movably connected inside the movable groove.
[0012] The present invention is further configured such that the stirring blade is made of stainless steel, and the stirring blade is used to stir the medicine.
[0013] The present invention is further configured such that bolts are fixedly connected to one side and the top of the mounting plate, and the eradication device is installed at the rear of the vehicle by means of bolts.
[0014] This utility model has the following beneficial effects:
[0015] This invention, through the installation of a drive motor, enables the soil-turning roller, stirring rod, and spray head to work in tandem, and utilizes a pulley system for power distribution. This effectively reduces the energy waste and equipment complexity caused by multiple power sources in traditional devices. The soil-turning roller efficiently loosens the soil, facilitating pesticide penetration. Meanwhile, the stirring rod and stirring blades ensure uniform mixing of the pesticide solution, preventing sedimentation and improving pesticide utilization. Furthermore, the reciprocating screw and movable rod enable the spray head to automatically oscillate, thereby expanding the pesticide coverage area and significantly improving application accuracy and operational efficiency, thus enhancing the eradication effect of Mikania micrantha.
[0016] This invention, through the design of a high-pressure water pump and hose, can deliver the liquid medicine to a swingable spray head. Combined with the reciprocating motion of the movable plate, the spraying range of the liquid medicine is wider and more evenly distributed, reducing waste and missed spraying. The cooperation of the limit rod and connecting plate ensures the stable operation of the threaded sleeve, while the design of the liquid inlet and tank cover facilitates the addition and sealed storage of the liquid medicine. This achieves the goal of optimizing power transmission and spraying method, realizing the dual objectives of energy saving, environmental protection and efficient treatment.
