Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0037] The following is combined with Figures 1 to 7 This invention describes the soil disinfection device and method provided by the present invention.

[0038] See Figures 1 to 3 As shown, the soil disinfection device provided in this embodiment of the invention includes: a body 10, a traveling unit 20, a moisture content detection unit 30, a spraying unit 40, and a disinfection unit 50.

[0039] The traveling unit 20 is located on the body 10 and is used to drive the body 10 to move. The disinfection unit 50 is located at the first end of the body 10. The moisture content detection unit 30 is located at the second end of the body 10. The spraying unit 40 is connected to the body 10 and is located inside the moisture content detection unit 30.

[0040] The moisture content detection unit 30 includes a roller 310, which is arranged along the width direction of the body 10 and rotatably connected to the body 10. The outer wall of the roller 310 is arrayed with probes 320 for detecting the distribution characteristics of moisture content in the soil.

[0041] The spraying unit 40 includes a liquid storage tank 410 and multiple nozzles 420. The multiple nozzles 420 are arranged along the width direction of the body 10 and connected to the liquid storage tank 410. The disinfection unit 50 includes multiple waveguides 510 for disinfecting the soil. The multiple waveguides 510 are all connected to the body 10 and are arranged along the width direction of the body 10.

[0042] The spraying unit 40 is used to acquire the water content distribution characteristic data of the probe 320 in the soil, and the spraying unit 40 is used to control the spraying operation of multiple nozzles 420 based on the water content distribution characteristic data.

[0043] It should be noted that the aforementioned "first end of fuselage 10" specifically refers to Figure 1 The front end of the fuselage 10 shown above, specifically the "second end of the fuselage 10" refers to... Figure 1 The rear end of the fuselage 10 shown in the diagram.

[0044] The soil disinfection device provided by this invention comprises a moisture content detection unit 30 and a disinfection unit 50 respectively installed at the first and second ends of the body 10, and a spraying unit 40 installed inside the moisture content detection unit 30. During soil disinfection, the traveling unit 20 drives the body 10 to move along the soil to be disinfected. The probes 320 on the roller 310 can penetrate into different positions of the soil to be disinfected and obtain the moisture content distribution characteristic data of the soil to be disinfected. The spraying unit 40 can control the opening of different nozzles 420 according to the moisture content distribution characteristic data of the soil to be disinfected, so as to control the spray volume corresponding to different nozzles 420, so that the moisture content of the soil to be disinfected is within a suitable range for disinfection. Then, the soil to be disinfected is subjected to high-temperature disinfection treatment through multiple waveguides 510 of the disinfection unit 50. The soil disinfection device provided by this invention solves the defects of existing disinfection equipment that cannot achieve comprehensive disinfection of bacteria, viruses and pests in the soil, greatly improves the disinfection effect of the device on the soil, and can effectively disinfect the soil.

[0045] Specifically, see Figures 1 to 3 As shown, in this embodiment, the disinfection unit 50 also includes a plurality of magnetic control devices 520 that are connected one-to-one with the waveguide 510. The magnetic control devices 520 can generate microwaves, and the waveguide 510 can conduct microwaves to the soil to be disinfected to heat the soil and thus achieve the disinfection effect.

[0046] The travel unit 20 is a tracked travel unit, which can drive the fuselage 10 along a set path in complex terrain.

[0047] In the spraying unit 40, there is at least one storage tank 410. For example, the spraying unit 40 may have a single storage tank 410 for storing water. Alternatively, the spraying unit 40 may have two storage tanks 410, both of which are connected to the nozzle 420. One storage tank 410 is used for storing water, and the other is used for storing disinfectant. The spraying of disinfectant can assist the disinfection unit 50 in disinfecting the soil.

[0048] See Figures 1 to 4 As shown, according to some embodiments of the present invention, the roller 310 is provided with a plurality of probe groups spaced apart along its width direction, and the probe group includes a plurality of probes 320 spaced apart along the circumference of the roller 310; the spraying unit 40 includes a plurality of nozzles 420 corresponding to the probe groups one by one, and the disinfection unit 50 includes a plurality of waveguides 510 corresponding to the probe groups one by one.

[0049] With the above settings, when the machine body 10 is moving, the roller 310 rolls forward, and multiple probe groups spaced apart along its width can detect the moisture content of different locations of the soil to be disinfected. Each probe group includes multiple probes 320 spaced apart along the circumference of the roller 310. During the rolling movement of the roller 310, the moisture content of the soil to be disinfected can be detected in all directions.

[0050] Multiple nozzles 420, each corresponding to a probe group, can control their opening or closing or opening degree according to the moisture content of the corresponding area of ​​the soil to be disinfected detected by the probe group. This allows for independent control of the spraying amount of the nozzles 420 for different areas of the soil to be disinfected, ensuring that the moisture content of different areas of the soil to be disinfected is within the range suitable for the waveguide 510 to disinfect, thereby improving the disinfection effect.

[0051] The multiple waveguides 510, each corresponding to a probe group, can perform disinfection operations on different areas of the soil to be disinfected.

[0052] See Figures 1 to 4 As shown, according to some embodiments of the present invention, the disinfection unit 50 includes multiple waveguide groups arranged adjacently along the length direction of the fuselage 10. Each waveguide group includes multiple waveguides 510 spaced apart along the width direction of the fuselage 10, wherein the waveguides 510 of the multiple waveguide groups are staggered in the width direction of the fuselage 10. By placing the waveguides 510 within multiple waveguide groups arranged adjacently along the length direction of the fuselage 10, it is possible to ensure that each waveguide 510 fully covers the soil to be disinfected while meeting the arrangement requirements of each component (such as the magnetic control device 520) in the disinfection unit 50.

[0053] Specifically, see Figure 4 As shown, a1 to a8 represent the projected areas of the waveguides on the ground, and B is the equivalent surface of the projected area. The waveguides 510 are staggered and spaced apart, with the arrows indicating the direction of travel of the fuselage 10. This design ensures that each waveguide 510 is fully irradiated by microwaves, equivalent to the pattern shown on the right (B). The centerlines of the probe group and the corresponding waveguide 510 are aligned on the same straight line.

[0054] See Figure 3 and Figure 5As shown, according to some embodiments of the present invention, the roller 310 includes a spindle 311, which is rotatably connected to the body 10. The outer wall of the spindle 311 is arrayed with multiple guide sleeves 330 corresponding one-to-one with the probes 320. One end of the probe 320 is slidably engaged with the guide sleeve 330. A spring 340 (with a set elastic modulus) is fitted onto the guide sleeve 330. One end of the spring 340 is connected to the guide sleeve 330, and the other end is connected to the probe 320. When the moisture content detection unit 30 is working, the roller 310 rolls against the soil to be disinfected. With the above configuration, when the probe 320 penetrates the soil, it can maintain its initial position under the action of the spring 340 to smoothly penetrate the soil. When the probe 320 penetrates a hard object such as a stone in the soil, it can automatically retract along its axial direction to prevent damage to the probe 320. When the probe 320 is pulled out of the soil, it can automatically reset under the action of the spring 340.

[0055] Specifically, in this embodiment, the bottom of the outer wall of the guide sleeve 330 and the outer wall of the probe 320 are both provided with flanges along the circumferential direction. The spring 340 is sleeved on the guide sleeve 330 and located between the two flanges. When the probe 320 is inserted into the soil and a hard object such as a stone, the probe 320 can retract along its axial direction and compress the spring 340. When the probe 320 is pulled out of the soil, the spring 340 can make the probe 320 return to its initial position.

[0056] Further, see Figure 3 and Figure 5 As shown, according to some embodiments of the present invention, the roller 310 further includes an outer cylinder 312 coaxially arranged with the mandrel 311. The outer cylinder 312 is sleeved on the mandrel 311, and a plurality of guide holes corresponding one-to-one with the guide sleeve 330 are arranged on the outer cylinder 312. The probe 320 passes through the guide holes and slides in cooperation with the guide holes. With the above arrangement, the guide holes on the outer cylinder 312 can guide the probe 320 when it moves telescopically, preventing the probe 320 from deviating from the axial direction and undergoing bending or other deformations.

[0057] See Figure 3As shown, according to some embodiments of the present invention, the moisture content detection unit 30 further includes a first support frame 350 and a first driving device 360. The first support frame 350 is hinged to the body 10, and the roller 310 is rotatably connected to the first support frame 350. The first driving device 360 ​​is disposed on the body 10, and its output end is connected to the first support frame 350 to drive the first support frame 350 to rotate around its hinge point with the body 10. With the above arrangement, the output end of the first driving device 360 ​​can drive the roller 310 and other components to rise or fall through the first support frame 350 to adapt to different road surface heights. By adjusting the extension length of the output end of the first driving device 360, the depth to which the probe 320 penetrates the soil to be disinfected can also be controlled. In addition, when the device is traveling on a road surface other than the one to be disinfected, the first driving device 360 ​​can lift the roller 310 and other components to prevent the probe from contacting the road surface.

[0058] Specifically, the first driving device 360 ​​is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, etc. In this embodiment, the first driving device 360 ​​is preferably an electric cylinder.

[0059] See Figure 3 As shown, according to some embodiments of the present invention, the spraying unit 40 further includes a second support frame 430, with a plurality of nozzles 420 spaced apart on the second support frame 430, and the second support frame 430 connected to the first support frame 350. By setting the second support frame 430 and connecting it to the first support frame 350, when the output end of the first driving device 360 ​​drives the first support frame 350 to move, it can synchronously drive the second support frame 430 to move, thereby adjusting the height and spraying angle of the nozzles 420. When adjusting the height and spraying angle of the nozzles 420, the spraying range of the nozzles 420 can be adjusted.

[0060] See Figure 2As shown, according to some embodiments of the present invention, the disinfection unit 50 further includes a third support frame 530, a bracket 540, a second drive device 550, and a third drive device (not shown in the figure). The third support frame 530 is slidably mounted on the body 10 in a vertical direction. One side of the bracket 540 is hinged to the third support frame 530. The waveguide 510 is mounted on the bracket 540. The second drive device 550 is mounted on the body 10, and its output end is connected to the third support frame 530 to drive the third support frame 530 to move vertically. The third drive device is mounted on the body 10, and its output end is connected to the bracket 540 to drive the bracket 540 to rotate around its hinge point with the third support frame 530. By setting up a third support frame 530, a bracket 540, a second drive device 550, and a third drive device, the output end of the second drive device 550 can drive the third support frame 530 and the components mounted on the third support frame 530 to move up and down, thereby adjusting the height of the waveguide 510. The output end of the third drive device can drive the bracket 540 to rotate around its hinge point with the third support frame 530, thereby adjusting the tilt angle of the waveguide 510.

[0061] Specifically, the machine body 10 has a vertically oriented sliding groove along its upper edge, and a fixing plate is connected to the third support frame 530. The fixing plate has a slider that slides in conjunction with the sliding groove. Both the second drive device 550 and the third drive device are electric cylinders, hydraulic cylinders, or pneumatic cylinders, etc. In this embodiment, it is preferred that the second drive device 550 and the third drive device are electric cylinders.

[0062] For example, if the disinfection device detects protruding foreign objects such as stones on the road surface during its operation, it can raise the third support frame 530 through the second drive device 550 to increase the height of the lower end of the waveguide 510. If necessary, it can also drive the bracket 540 to rotate around the hinge point between itself and the third support frame 530 through the third drive device to adjust the tilt angle of the waveguide 510 and achieve obstacle avoidance function.

[0063] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the soil disinfection device further includes an energy power unit 60 and a power conversion unit 70. Both the energy conversion unit and the traveling unit 20 are electrically connected to the energy power unit 60, and the disinfection unit 50 is electrically connected to the power conversion unit 70. The energy power unit 60 can provide energy (such as electrical energy) to the disinfection unit 50 and the traveling unit 20, and the energy conversion unit can convert the electrical energy provided by the energy power unit 60 into the voltage required by the waveguide 510, preparing for microwave generation.

[0064] Specifically, in this embodiment, the power unit 60 is a dual-module unit. One module is electrically connected to the traveling unit 20, providing power to the traveling unit 20, and the other is electrically connected to the disinfection unit 50, providing power to the disinfection unit 50. This enables the traveling unit 20 and the disinfection unit 50 to be powered independently.

[0065] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the soil disinfection device further includes a terrain detection unit 80 and an obstacle detection unit 90. The terrain detection unit 80 includes an ultrasonic sensor 810 and an alarm 820. Both the ultrasonic sensor 810 and the alarm 820 are connected to the body 10. The obstacle detection unit 90 is communicatively connected to the alarm 820.

[0066] By incorporating a terrain detection unit 80, the ultrasonic sensor 810 can detect the height of the chassis 10 relative to the ground, providing support for the lifting and lowering adjustment of the disinfection unit 50. By incorporating an obstacle detection unit 90, obstacle information around the disinfection device can be detected. When an obstacle is present, an alarm 820 can be activated. For example, when the disinfection device is operating, if the obstacle detection unit 90 detects someone approaching the device, the alarm 820 can sound an alarm, reminding personnel to stay away and maintain a safe distance from the device to prevent collisions or to avoid microwave leakage that could harm people.

[0067] Specifically, in this embodiment, the terrain detection unit 80 further includes a sensor mounting bracket 830 and an alarm mounting plate 840. Both the sensor mounting bracket 830 and the alarm mounting plate 840 are located on the body 10. The ultrasonic sensor 810 is fixed by the sensor mounting bracket 830, and the alarm 820 is fixed by the alarm mounting plate 840.

[0068] The soil disinfection method provided by the present invention is described below. The soil disinfection method described below can be referred to in correspondence with the soil disinfection device described above.

[0069] See Figure 6 As shown in the figure, the soil disinfection method provided in this embodiment of the invention includes the following steps.

[0070] S610. Obtain the moisture content distribution characteristics of the soil to be treated.

[0071] S620. Based on the moisture content distribution characteristics of the soil to be disinfected, control the spraying material and corresponding spraying amount of each nozzle 420 so that the moisture content of different areas of the soil to be disinfected is controlled within a preset range.

[0072] The soil disinfection method provided by this invention obtains the moisture content distribution characteristics of the soil to be disinfected and controls the spraying material and corresponding spraying amount of each nozzle 420 according to these characteristics. This ensures that the moisture content of different areas of the soil to be disinfected is controlled within a preset range, and the disinfection unit 50 can achieve a better disinfection effect. This method overcomes the shortcomings of existing disinfection equipment, which cannot comprehensively eliminate bacteria, viruses, and pests in the soil, greatly improving the device's disinfection effect and enabling effective disinfection of the soil.

[0073] Specifically, in step S610, as the machine body 10 moves along the soil to be disinfected, the probes 320 distributed along the width direction on the roller 310 can penetrate into the soil to be disinfected, thereby obtaining the moisture content distribution characteristics of the soil to be disinfected.

[0074] In step S620, the spraying unit 40 can control the opening of each nozzle 420 according to the moisture content distribution characteristics of the soil to be disinfected, thereby controlling the spray volume. For example, if the moisture content of the soil to be disinfected in the current range is within a set range, the corresponding nozzle 420 will not work. If the moisture content of the soil to be disinfected in the current range is less than the set range, the opening of the nozzle 420 can be adjusted according to the difference between the moisture content of the soil to be disinfected in the current range and the set range to replenish the moisture of the soil to be disinfected in the current range, so that its moisture content rises to the set range.

[0075] During steps S610 and S620, the disinfection unit 50 is in the activated state, which can output microwaves to heat the soil to be disinfected when the moisture content is within the set range, so as to achieve a better disinfection effect.

[0076] In addition, as the machine body 10 moves toward the soil to be disinfected, the ultrasonic sensor 810 can detect the height of the chassis of the machine body 10 relative to the ground. Based on this, the height of the moisture content detection unit 30 (roller 310) and the disinfection unit 50 (waveguide 510) is controlled to prevent collision with the ground.

[0077] During disinfection operations, the obstacle detection unit 90 is activated, continuously monitoring obstacles around the disinfection device. If personnel are present within a safe distance, the disinfection unit 50 stops, suspending the disinfection operation.
