Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plasma technology and relates to a discharge electrode, particularly to a plasma-to-ground discharge nail head electrode and a soil treatment device. Background Technology
[0002] In agricultural production, the soil of cultivated land contains a certain amount of pest eggs and weed seeds, which seriously affect the growth of subsequent crops. People usually use chemical agents (such as herbicides) to kill or inhibit the growth of weeds and insect eggs. Although the elimination speed is fast and the effect is significant, it will pollute the soil, water sources and ecological environment, and will also lead to increased resistance to herbicides or mutations, making it more difficult to control.
[0003] Fertilizers in the soil play an important role in the growth of crops. People need to frequently apply chemical fertilizers to quickly enrich the soil. However, the long-term use of pesticides and chemical fertilizers also affects the soil quality, and pesticide residues can actually harm the soil and crops.
[0004] With the development of industrialization, human pollution of soil has become increasingly serious. Air pollution, water pollution, and solid waste pollution also indirectly pollute the soil, further threatening the human environment, crop growth, and food safety. As science and technology continue to advance and environmental protection requirements become increasingly stringent, soil remediation must also become more sophisticated. Traditional chemical remediation is costly and prone to causing secondary pollution. Bioremediation, while environmentally friendly, has a long cycle and requires the soil environment to adapt to biological reactions. Phytoremediation itself also consumes certain nutrients, which can lead to soil depletion. Traditional physical remediation methods, such as soil replacement, topsoil application, and solidification, involve too much engineering work and are costly.
[0005] To solve the above problems, there is an urgent need to develop a device that can effectively disinfect pests and weeds in the soil, promote green fertilization, and restore the soil. Utility Model Content

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0028] like Figures 1-3 As shown, this utility model provides a plasma-to-ground discharge nail electrode 1, including a frame 11, a plurality of nails 12, an insulating member 13, and a power source. The plurality of nails 12 are arranged in a row, with their upper ends fixed in the frame 11, forming a rake-like structure. The insulating member 13 is disposed between the nails 12 and the frame 11, isolating the nails 12 from the frame 11. The plurality of nails 12 are electrically connected to the power source via wires, applying voltage to the nails 12.
[0029] Specifically, such as Figure 3 As shown, the frame 11 has a horizontally arranged mounting plate 111. The mounting plate 111 has several through mounting holes. Several nail heads 12 correspond one-to-one with the several mounting holes and are fixed in the corresponding mounting holes.
[0030] The number of insulating components 13 is equal to the number of mounting holes, and they correspond one-to-one. For example... Figure 4 As shown, the insulating component 13 includes a lower insulating pad 131 and an upper insulating pad 132. The top of the lower insulating pad 131 has a protrusion that matches a mounting hole. The main body of the lower insulating pad 131 is positioned below the mounting plate 111, with the protrusion extending upward from the mounting hole. The bottom of the upper insulating pad 132 has a groove that matches the protrusion. The upper insulating pad 132 is positioned above the mounting plate 111, with the groove covering the protrusion extending from the mounting hole. The nail head 12 includes a nail body 121 and a fixing bolt 122. The upper end of the nail body 121 is inserted into the bottom of the lower insulating pad 131, and the fixing bolt 122 passes through the upper insulating pad 132 and the lower insulating pad 131 and is threadedly connected to the upper end of the nail body 121 for fixation. The wire is connected to the fixing bolt 122 of the nail head 12.
[0031] like Figure 1 and Figure 2 As shown, the nail head electrode 1 also includes a nail head dust cover 14. The nail head dust cover 14 is fixed above the frame 11 and can cover all the nail heads 12 to prevent dust and debris from entering and causing a short circuit in the equipment.
[0032] like Figure 6 and Figure 7 As shown, this utility model also provides a soil treatment device, including the aforementioned nail-head electrode 1. (As shown...) Figure 5 As shown, several nail heads 12 are divided into two groups. Each group of nail heads 12 is connected in series by wires to form two sets of series electrodes, which are connected to different wires respectively, thereby forming different electrodes by applying different voltages. Preferably, the two groups of nail heads 12 are arranged alternately. The two sets of series electrodes of the nail head electrode 1 form an electrode pair. The two sets of series electrodes of the electrode pair are a positive high-voltage electrode and a negative high-voltage electrode, respectively. The positive high-voltage electrode / negative high-voltage electrode refers to an electrode with an absolute voltage of 2 to 10 kV. Alternatively, the two sets of series electrodes are high-voltage differential electrodes, which refer to a pair of electrodes with a differential voltage of ±2 to ±10 kV.
[0033] The soil treatment device also includes a vehicle 2 capable of moving on the soil. The nail-head electrode is connected to the vehicle and moves with the vehicle on the soil.
[0034] The carrier 2 is equipped with a lifting and lowering component. The nail head electrode 1 is connected to the carrier 2 via the lifting and lowering component. The lifting and lowering component can insert the nail head electrode 1 downward into the soil and lift the nail head electrode 1 upward out of the soil. When the carrier 2 moves the nail head electrode 1 on the soil, the lifting and lowering component lifts the nail head electrode 1 out of the soil; when it stops, the lifting and lowering component inserts the nail head electrode 1 back into the soil.
[0035] Specifically, the lifting and lowering components include a hydraulic rod mounting bracket 211, a hydraulic rod 21, a first traction rod 221, and a second traction rod 222. The nail head electrode 1 is equipped with a connecting rod 15 and a connecting frame 16 fixed to the frame 11. The connecting rod 15 is located on the front side of the nail head electrode 1, and the connecting frame 16 is located above the nail head electrode 1. The hydraulic rod mounting bracket 211 is fixed to the carrier 2 and located above the connecting rod 15. The upper end of the hydraulic rod 21 is hinged to the hydraulic rod mounting bracket 211, and the lower end is hinged to the middle of the connecting rod 15. The end of the connecting rod 15 is hinged to the carrier 2. When the hydraulic rod 21 extends, it pushes the connecting rod 15 down until the nail head electrode 1 is inserted into the soil. When the hydraulic rod 21 shortens, it lifts the connecting rod 15 until the nail head electrode 1 is detached from the soil. One end of the first traction rod 221 is hinged to the carrier 2, and the other end is hinged to one end of the second traction rod 222. The other end of the second traction rod 222 is hinged to the connecting frame 16, serving to strengthen the connection.
[0036] The working process of the soil treatment device is as follows: positive high voltage electrode and negative high voltage electrode are respectively loaded with positive high voltage and negative high voltage with an absolute voltage of 2 to 10 kV, or high voltage differential electrode is loaded with differential high voltage with a differential voltage of ±2 to ±10 kV. The carrier 2 pulls the nail head electrode 1 to move on the soil, and the two sets of series electrodes discharge to the soil, generating active particles to repair and fertilize the soil.
[0037] Specifically, the nail head 12 of the nail electrode 1 is inserted into the soil and makes full contact with the soil interior. The plasma discharges and treats the soil in a shallow layer, causing active particles to adhere to the soil and directly disinfect the insects and grass inside. The air inside is ionized to form nitrogen-oxygen plasma that degrades pollutants in the soil. Since it is inside, the active nitrogen generated is more easily retained and absorbed by the soil, thus playing a role in fertilizing the soil.
[0038] When the electrode pair consists of a positive high-voltage electrode and a negative high-voltage electrode, for the positive high-voltage electrode, the soil is at grounded 0 potential, and the discharge is mainly concentrated in the shallow layer of soil in contact with the electrode. The electrode discharges more easily, and the soil surface discharge is relatively strong, making it suitable for deep treatment of shallow soil. It has strong oxidizing properties, and the high-energy particles bombard the surface soil with high intensity, resulting in significant shallow pest and weed control. For the negative high-voltage electrode, although the soil layer is still at grounded 0 potential, it is at a high potential relative to the negative high voltage. The surface discharge is relatively weak, but soil particles are more likely to induce positive charges and cause micro-discharges towards the low-voltage electrode, which is beneficial for soil treatment with a certain depth when the electrode contacts the soil. When the electrode pair is a high-voltage differential electrode, the positive and negative high voltages of the high-voltage differential electrode can also take into account both surface discharge and deep soil micro-discharge, achieving comprehensive pest control and increasing the treatment area and depth.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
