Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a multimodal portable weed removal device. Background Technology

[0002] When applying for this invention, the applicant searched and found that a Chinese patent disclosed a "high-voltage variable frequency weeding robot" with application number "CN202011217527.1". Although it has voltage regulation function, it cannot realize AC / DC multi-mode output and dynamic waveform adjustment. In addition, the control strategy of AC / DC hybrid power system has been applied in the field of microgrid, but has not yet been combined with agricultural devices.

[0003] Existing weeding devices remove weeds using the principle of high-voltage discharge. By forming a high-voltage discharge circuit on the ground surface with the positive electrode and the first negative electrode, surface weeds and shallow weed roots can be removed. By forming a high-voltage discharge circuit with the second negative electrode and the positive electrode deep underground, deep weed roots can be removed, thus thoroughly removing weeds. However, when the front and rear wheels move, the electrodes crawl on the ground like a rake, creating significant resistance. This makes the device difficult to push smoothly and strenuous to operate, and can easily cause operator fatigue. Therefore, a multimodal portable weeding device is needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multimodal portable weed removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multimodal inter-field weeding portable device, comprising a connector, wherein nylon shafts are rotatably connected to both ends of the connector, and a second discharge cage and a first discharge cage are respectively fixedly connected to the ends of the two nylon shafts; a plurality of sets of first electrode pointed screws are fixedly connected to the outside of the first discharge cage, and a plurality of sets of second electrode pointed screws are fixedly connected to the outside of the second discharge cage; an installation groove and a connecting hole are provided inside the connector; an insulating rod is inserted into the installation groove; a limit bolt is installed inside the insulating rod; and the insulating rod is fixedly connected to the connector through the limit bolt and the connecting hole.

[0006] A mounting bracket is fixedly connected to the circumferential surface of the insulating rod. A first mounting base and a second mounting base are fixedly connected to the outside of the mounting bracket. A high-voltage electric generator is fixedly connected to the top of the first mounting base, and the high-voltage electric generator is connected to the electrodes of the first discharge cage and the second discharge cage.

[0007] Furthermore, a protection module is installed on the top of the second mounting base, the protection module including integrated overvoltage, overcurrent, short circuit, and temperature protection.

[0008] Furthermore, a limiting groove is formed on the circumferential surface of the insulating rod, and a waterproof top cover is inserted into the limiting groove. A wiring hole is formed on the side end face of the waterproof top cover.

[0009] Furthermore: the bottom of the waterproof top cover is threaded with a limiting screw, and the outside of the limiting screw is movably connected to a waterproof bottom cover, which fits snugly against the waterproof top cover.

[0010] Furthermore, an operating handle is fixedly connected to the end of the insulating rod away from the connector, and the outside of the operating handle is provided with anti-slip texture.

[0011] Furthermore, the bottom of the insulating rod is provided with a storage groove, and a bracket is rotatably connected inside the storage groove. A limit ring is threadedly connected to the outside of the insulating rod, and the positions of the bracket and the limit ring correspond to each other.

[0012] The present invention has the following beneficial effects:

[0013] 1. Compared with existing technologies, this device, by setting up a high-voltage electric generator, a first discharge cage, and a second discharge cage, allows for weed control. When in use, the high-voltage electric generator is activated, energizing the second discharge cage and the positive second electrode on the first discharge cage via a circuit. Utilizing the principle of high-volt electricity, the current is conducted into the plant, destroying the plant cell structure and ultimately causing the plant to die, thus achieving the purpose of weed control. This method not only effectively removes weeds but also poses no harm to the environment or human health. During operation, the nail-shaped pointed screws on the first and second electrodes can be better inserted into the ground, and the roller-type first and second discharge cages greatly reduce resistance when pushing or dragging, improving the ease of operation.

[0014] 2. Compared with the existing technology, this device is equipped with a waterproof top cover and a waterproof bottom cover. During use, the device uses limit screws to connect the waterproof top cover and the waterproof bottom cover, thereby protecting the high-voltage generator and protection module from rain damage and extending their service life.

[0023] Reference Figure 1-6 The present invention provides a multimodal portable weed removal device: including a connector 1, with nylon shafts 6 rotatably connected to both ends of the connector 1. The ends of the two nylon shafts 6 are respectively fixedly connected to a second discharge cage 8 and a first discharge cage 7. Conductive slip rings are installed between the nylon shafts 6 and the second discharge cage 8 and the first discharge cage 7, and current is transmitted through contact to achieve energization. Several sets of first electrode pointed screws 9 are fixedly connected to the outside of the first discharge cage 7, and several sets of second electrode pointed screws 10 are fixedly connected to the outside of the second discharge cage 8. The connector 1 has an installation groove 2 and a connection hole 3 inside. An insulating rod 4 is inserted into the installation groove 2. A limit bolt 5 is installed inside the insulating rod 4, and the insulating rod 4 is fixedly connected to the connector 1 through the limit bolt 5 and the connection hole 3.

[0024] A mounting bracket 11 is fixedly connected to the circumferential surface of the insulating rod 4. A first mounting base 12 and a second mounting base 14 are fixedly connected to the outside of the mounting bracket 11. A high-voltage electric generator 13 is fixedly connected to the top of the first mounting base 12, and the high-voltage electric generator 13 is connected to the electrodes of the first discharge cage 7 and the second discharge cage 8. When the device is in use, the high-voltage electric generator 13 is activated, energizing the second electrodes on the second discharge cage 8 and the first discharge cage 7 through the circuit. This causes the pointed screws installed on the second electrodes to contact the ground, thereby utilizing the principle of high-voltage electricity to conduct current into the plant, destroying the plant cell structure and ultimately causing the plant to die, thus achieving the purpose of weed control. This method not only effectively removes weeds but also poses no harm to the environment or human health. During operation, the first electrode pointed screw 9 and the second electrode pointed screw 10 are nail-shaped. It can be better inserted into the ground, and the roller-type first discharge cage 8 and second discharge cage 7 can greatly reduce the resistance when pushing or dragging, which is conducive to improving the ease of operation of the device. It utilizes a multi-mode power supply system, integrating AC and DC dual output modes, with a voltage dynamic range of 1kV-40kV and a current dynamic range of 10mA-1000mA. It supports dynamic switching of waveforms such as sine wave, square wave, sawtooth wave, and pulse wave. The device is compact and lightweight, easy to operate, and can also be used for single-person operation in places such as tobacco gardens, tea gardens, gardens, and roadsides.

[0025] A protection module 15 is installed on the top of the second mounting base 14. The protection module 15 integrates overvoltage, overcurrent, short circuit, and temperature protection. The protection module 15 can better ensure the safety of the device operation.

[0026] A limiting groove 16 is formed on the circumferential surface of the insulating rod 4, and a waterproof top cover 17 is inserted into the limiting groove 16. A wiring hole is formed on the side end face of the waterproof top cover 17. The wiring hole can be used to connect the wires connected to the high-voltage generator 13 to the first discharge cage 7 and the second discharge cage 8 respectively.

[0027] The bottom of the waterproof top cover 17 is threaded with a limiting screw 19, and a waterproof bottom cover 18 is movably connected to the outside of the limiting screw 19. The waterproof bottom cover 18 fits snugly against the waterproof top cover 17. During use, the limiting screw 19 connects the waterproof top cover 17 and the waterproof bottom cover 18, thereby protecting the high-voltage generator 13 and the protection module 15 from damage caused by rainwater, which helps to extend their service life.

[0028] An operating handle 23 is fixedly connected to the end of the insulating rod 4 away from the connector 1, and the outer surface of the operating handle 23 is provided with anti-slip texture. The operating handle 23 facilitates pushing or dragging the device.

[0029] The bottom of the insulating rod 4 has a storage groove 20, and a bracket 21 is rotatably connected inside the storage groove 20. A limit ring 22 is threadedly connected to the outside of the insulating rod 4, and the bracket 21 and the limit ring 22 are positioned correspondingly. The bracket 21 can be used to support the device when resting, preventing the operating handle 23 from falling to the ground and getting dirty. When not in use, it can be stored inside the storage groove 20, and the limit ring 22 can be rotated to limit its movement.

[0030] Working principle: When the device is in use, the high-voltage generator 13 is activated, and the second electrodes on the second discharge cage 8 and the first discharge cage 7 are energized through the circuit. This causes the pointed screws installed on the second electrodes to contact the ground, thereby using the principle of high-volt electricity to conduct current into the plant, destroying the plant cell structure and ultimately causing the plant to die, thus achieving the purpose of weeding. This method can not only effectively remove weeds, but also has no harm to the environment or human health. During operation, the nail-shaped pointed screws 9 and 10 of the first and second electrodes can be better inserted into the ground, and the roller-type first and second discharge cages 8 and 7 can greatly reduce the resistance when pushing or dragging, which is conducive to improving the ease of operation of the device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
