Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

The reset component is arranged on the outer side of the corresponding vertical side of the U-shaped frame 2 and is used to reset the marking component;

[0034] As described above, when the probe 7 moves downward, the paintbrush 19 can draw the soil moisture content on the sticker 13 in real time, so as to make the test results of the soil moisture detection clear, intuitive and comparable, and it can be clearly known where the soil moisture is the highest and where it is the lowest.

[0035] Please refer to the attached Figure 1 - attached Figure 4, in a preferred embodiment, the test component includes: a horizontal plate 3, which is horizontally arranged between the two vertical sides of the U-shaped frame 2. At the center of the bottom of the horizontal plate 3, an installation box 5 is fixedly installed, and two symmetrically arranged vertical rods 6 are vertically fixed at the bottom of the installation box 5. Probes 7 are fixedly installed at the ends of the two vertical rods 6. A telescopic electric rod 4 is vertically fixedly installed at the top of the horizontal side of the U-shaped frame 2, and the output end of the telescopic electric rod 4 passes through the horizontal side of the U-shaped frame 2. The output end of the telescopic electric rod 4 is fixedly installed on the top of the horizontal plate 3. A first telescopic rod 27 connected to the top of the horizontal plate 3 is vertically fixed at the bottom of the horizontal side of the U-shaped frame 2;

[0036] Specifically, when the horizontal plate 3 moves downward, it drives the installation box 5 and the U-shaped plate 11 to move downward. When the installation box 5 moves downward, it drives the vertical rods 6 and the probes 7 to move downward. When the probes 7 move downward, they will pass through the base 1 and insert into the soil.

[0037] Please refer to the appendix Figure 1 - appendix Figure 7 , in a preferred embodiment, the marking component includes: a connecting plate 10, which is arranged on the outer shell of the vertical side of the U-shaped frame 2, and the connecting plate 10 and the vertical side of the U-shaped frame 2 do not directly contact. Two vertical grooves 8 are vertically opened on the outer side of the vertical side of the U-shaped frame 2. First sliders 9 are slidably installed in the two vertical grooves 8, and the ends of the two first sliders 9 are fixedly installed on the side of the connecting plate 10. A U-shaped plate 11 is fixedly installed on the side of the horizontal plate 3, and the other end of the U-shaped plate 11 is fixedly installed on the end face of the connecting plate 10. An electromagnet 30 with a built-in power source is fixedly installed on the side of the connecting plate 10 away from the U-shaped frame 2. Cables are fixedly installed at the tops of the two probes 7, and the two cables are electrically connected to the electromagnet 30 through the installation box 5. A sticker 13 is pasted on the side of the U-shaped frame 2. A magnetic plate 16 is also slidably arranged on the side of the connecting plate 10 away from the U-shaped frame 2. A first horizontal groove 14 is opened on the side of the connecting plate 10, and a first movable block 15 is slidably installed in the first horizontal groove 14. The end face of the first movable block 15 is fixedly installed on the side of the magnetic plate 16. A first spring rod 31 is horizontally fixedly installed at the inner end of the first horizontal groove 14, and the telescopic end of the first spring rod 31 is fixedly installed on the side of the first movable block 15. A second horizontal groove 32 is opened on the side of the magnetic plate 16 away from the electromagnet 30, and a second movable block 33 is slidably installed in the second horizontal groove 32. A connecting column 17 is horizontally fixedly installed at the end face of the second movable block 33, and a three-jaw chuck 18 is fixedly installed at the end of the connecting column 17 away from the second movable block 33. A paintbrush 19 is installed on the three-jaw chuck 18, and the initial position of the paintbrush 19 is in contact with the sticker 13;

[0038] Preferably, since the more moisture in the soil, the lower the resistance and the stronger the fluidity of the current, when there is more moisture in the soil, the current passing through the electromagnet 30 is greater, and then the magnetic force of the electromagnet 30 is greater. Further, it can be known that the moisture content in the soil is proportional to the magnetic force of the electromagnet 30.

[0039] Please refer to the attached Figure 2 - Attachment Figure 7 In a preferred embodiment, the reset assembly includes: a limit plate 12, which is vertically and fixedly installed on the outer side of the corresponding vertical side of the U-shaped frame 2. The side of the limit plate 12 is provided with a first straight groove 25 and a second straight groove 26 arranged in parallel, and the side of the limit plate 12 is also provided with a first inclined groove 24 and a second inclined groove 29. The first inclined groove 24 and the second inclined groove 29 are located at both ends of the first straight groove 25 and the second straight groove 26, and the first inclined groove 24, the second inclined groove 29, the first straight groove 25 and the second straight groove 26 are connected end to end. The inner walls of the first straight groove 25, the second inclined groove 29 and the second straight groove 26 are provided with inner grooves 28, and the inner groove 28 is provided with a slope at the end of the second straight groove 26. A sliding column 23 is slidably arranged inside the first inclined groove 24, the second inclined groove 29, the first straight groove 25 and the second straight groove 26, and the end of the sliding column 23 passes through the limit plate 12. The end of the sliding column 23 is provided with an inner cavity, and a second spring rod 34 is embedded inside the inner cavity. The telescopic end of the second spring rod 34 is adapted to the inner groove 28. A second collar 22 is fixedly sleeved on the surface of the sliding column 23, and a first collar 20 is slidably sleeved on the surface of the connecting column 17 by splines. A connecting rod 21 is fixedly connected between the first collar 20 and the second collar 22;

[0040] Furthermore, the second spring rod 34 will pass through the slope on the inner groove 28, causing the end of the sliding column 23 to slide inside the second straight groove 26. When the sliding column 23 slides to the connection between the second straight groove 26 and the first inclined groove 24, the sliding column 23 will move through the first inclined groove 24 into the first straight groove 25.

[0041] The working principle of the present invention: First, move the device to the detection position in the wheat planting field, and stick the sticker 13 on the corresponding vertical side of the U-shaped frame 2;

[0042] Then start the electric telescopic rod 4 to drive the cross plate 3 to move downward. The downward movement of the cross plate 3 drives the installation box 5 and the U-shaped plate 11 to move downward. The downward movement of the installation box 5 drives the vertical rod 6 and the probe 7 to move downward. The downward movement of the probe 7 will pass through the base 1 and insert into the soil;

[0043] The downward movement of the U-shaped plate 11 drives the connecting plate 10 to move downward. The downward movement of the connecting plate 10 drives the electromagnet 30 and the magnetic plate 16 to move downward. The downward movement of the magnetic plate 16 drives the connecting column 17 and the three-jaw chuck 18 to move downward. The downward movement of the three-jaw chuck 18 drives the paintbrush 19 to move downward, thus enabling the drawing of lines on the sticker 13. Since the more moisture there is in the soil, the lower the resistance and the stronger the fluidity of the current, when there is more moisture inside the soil, the current passing through the electromagnet 30 is greater, and then the magnetic force of the electromagnet 30 is greater. Further, it can be known that the moisture content of the soil is proportional to the magnetic force of the electromagnet 30. After the electromagnet 30 generates magnetic force, it will cause the magnetic plate 16 to move towards the electromagnet 30. The movement of the magnetic plate 16 drives the second movable block 33 and the first movable block 15 to move and makes the first spring rod 31 generate elastic force. The movement of the second movable block 33 drives the connecting column 17 to move. The movement of the connecting column 17 drives the three-jaw chuck 18 and the paintbrush 19 to move horizontally, so that a broken line can be drawn on the sticker 13. Further, the moisture content inside the soil can be judged by observing the shape of the broken line on the sticker 13, and the moisture detection of the soil is convenient and fast. It should be noted that the movement of the connecting column 17 drives the first collar 20 and the connecting rod 21 to move downward. The downward movement of the connecting rod 21 drives the second collar 22 and the sliding column 23 to move downward. The downward movement of the sliding column 23 drives the second spring rod 34 to move downward. When reaching the lowest detection depth, the second spring rod 34 will enter the inner groove 28;

[0044] When the detection of the moisture inside the soil is completed and the electric telescopic rod 4 contracts to drive the cross plate 3 and its connecting components to move upward together, due to the setting of the inner groove 28, the second spring rod 34 will move along the path of the inner groove 28. Further, the sliding column 23 can enter the second straight groove 26 through the second inclined groove 29. The movement of the sliding column 23 away from the U-shaped frame 2 drives the second collar 22, the connecting rod 21, the first collar 20, the connecting column 17, the second movable block 33, the three-jaw chuck 18 and the paintbrush 19 to move away from the U-shaped frame 2. Further, the paintbrush 19 and the sticker 13 can be separated, avoiding the interference of the paintbrush 19 drawing lines on the sticker 13 during reset. Finally, the second spring rod 34 will pass through the slope on the inner groove 28, so that the end of the sliding column 23 slides inside the second straight groove 26, and when the sliding column 23 slides to the connection between the second straight groove 26 and the first inclined groove 24, the sliding column 23 will move through the first inclined groove 24 into the first straight groove 25;

[0045] In summary, by repeating the above steps in sequence, the moisture in the soil of the wheat field can be continuously detected. The detection results are clear, intuitive and comparable, which is convenient for quickly judging where the moisture content in the soil is the highest, thus improving the use effect of the device.

[0046] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
