[0003] Reference announcement number "CN216434108U" discloses "A portable device for detecting soil nutrients in medicinal herb planting areas," which describes a device comprising: a base, with pillars welded and fixed at the four corners of the base's bottom, and rollers installed on the bottom surface of each pillar; a push handle and a soil sample classification box frame welded and fixed at the top of both ends of the base, and a detection mechanism for detecting soil nutrients located above the soil sample classification box frame. This invention classifies and stores various soil samples collected from medicinal herb planting areas in soil sample containers within the soil sample classification box frame. The piston rod of the first cylinder extends, driving the soil nutrient detector downwards to detect the nutrients in the soil samples. The operator can change the position of the soil nutrient detector by changing the position of the mounting plate, facilitating the detection of soil samples in multiple soil sample containers. When the operator pushes the push handle, it drives the rollers to roll, thereby moving the entire device, which is relatively labor-saving.

[0004] In the process of implementing this patent, the applicant discovered the following technical problems: the content of the detected factors varies in soil at different depths, which limits the applicability of the device; furthermore, it is inconvenient to carry outdoors for real-time testing, making it difficult to meet diverse usage needs under different conditions.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] like Figure 1As shown, this medicinal herb planting soil testing device includes a detector 1, including but not limited to a detector 1 whose type is determined according to the soil factors being measured. For example, when it is necessary to test the humidity, heavy metals, or pH of the soil for planting medicinal herbs, it is a humidity, heavy metal, or pH detector 1. In this example, the detector 1 is limited to an active contact type with a probe 2. The probe 2 is integrated with a sensor for detecting humidity, heavy metals, or pH. For example, when detecting soil humidity, the sensor of the probe 2 placed in the soil will absorb the water contained in the soil. At the same time as absorption, the conductivity will change. This change is read by the processor and converted into an analog signal or a digital signal according to a certain rule, and finally the corresponding humidity value is displayed on the detector 1.

[0038] The bottom of the detector 1 is provided with a base 10, which is used to support the detector 1 and allows the user to better hold the detector 1. A guide cylinder 3 is rotatably connected to the bottom of the base 10. The probe 2 of the detector 1 is located inside the guide cylinder 3. The guide cylinder 3 restricts the probe 2 to move within the guide cylinder 3 at a fixed length. Specifically, it determines the length of the probe 2 that protrudes from the guide cylinder 3, so as to control the depth of the probe 2 into the soil and achieve the detection of the content of the tested factor in the soil at different depths.

[0039] A pressure plate 4 is also connected to the probe rod 2 located inside the guide cylinder 3. A part of the pressure plate 4 extends out of the guide cylinder 3. The probe rod 2 is moved in the guide cylinder 3 by the touch of the pressure plate 4. Since the probe rod 2 needs to enter the soil without the detector 1 moving, the probe rod 2 and the detector 1 are flexibly and stretchably connected. Thus, the movement of the probe rod 2 into the soil does not affect the detection feedback connected to the detector 1 (details below).

[0040] A fixing component 5 is provided at the bottom of the base 10. Since the base 10 and the guide cylinder 3 are rotatably connected, the base 10 is fixed to the guide cylinder 3 by rotating relative to the guide cylinder 3 or vice versa, thereby forming the base 10 and the guide cylinder 3 in the first and second forms. The first form is as follows: Figure 1 The unfolded state shown is the state of being tested; the second state is as follows. Figure 2 The fold shown is in a portable form.

[0041] like Figure 3 As shown, the base 10 has a slot that can be elastically deformed. Specifically, the depth and width of the slot are determined according to the specific shape of the detector 1. The thinner wall part of the slot can be deformed under pressure. When part of the detector 1 is placed in the slot, the thinner wall part of the slot slightly expands and adheres to the detector 1, so that the detector 1 is fixed on the base 10.

[0042] The bottom end of the probe 2 is sharp so that it can be inserted into the soil. The top end of the probe 2 is fixed with a spiral wire 6. The top end of the spiral wire 6 passes through the base 10 and is electrically connected to the detector 1. The spiral wire 6 is similar in shape to a spring and can be deformed when stretched or rotated in any direction. Thus, the probe 2 can still maintain its connection with the detector 1 when it enters the soil and when it is deformed from the first form to the second form.

[0043] like Figure 4 As shown, the guide tube 3 includes two first through pipes 31 and two second through pipes 32 (including but not limited to these). Each of the two first through pipes 31 and the two second through pipes 32 has a through groove 7. Each of the two first through pipes 31 is connected to one end of each of the two second through pipes 32 by a screw connector 8. The two second through pipes 32 are also connected to each other by a screw connector 8. The screw connector 8 is used to align or stagger the through groove 7 of the first through pipe 31 and one of the second through pipes 32, or the through grooves 7 of the two second through pipes 32.

[0044] By rotating the screw connector 8, the through groove 7 of the upper second through pipe 32 is aligned with the through groove 7 of the top first through pipe 31. Then, by rotating the screw connector 8, the through groove 7 of the other second through pipe 32 is rotated to intersect with the through groove 7 of the upper second through pipe 32, thus forming a... Figure 4 The guide cylinder 3 shown is such that the probe 2 inside the guide cylinder 3 is limited to the groove 7 between the first through pipe 31 at the top and a second through pipe 32 above, and moves downward, so that the probe 2 protrudes into the guide cylinder 3. The length of the guide cylinder 3 is equal to the length of the groove 7 of the first through pipe 31 plus the length of the groove 7 of the second through pipe 32.

[0045] When the connecting piece 8 rotates to align the through slots 7 of the two second through pipes 32, and then aligns the through slots 7 of the second through pipes 32 with the through slots 7 of the two first through pipes 31 respectively, the through slots 7 of the guide cylinder 3 as a whole are in a state of alignment. Figure 1 In the vertical position, the guide cylinder 3 can move between the two first through pipes 31 and the two second through pipes 32, so that the length of the probe rod 2 protruding from the guide cylinder 3 is equal to the superimposed length of the through grooves 7 of the two first through pipes 31 and the two second through pipes 32.

[0046] like Figure 5 As shown and referenced Figure 4 Each of the screw-in components 8 includes two sets of grooves 81 and a retaining ring 82. The two sets of grooves 81 are integrally connected to the ends of the first through pipe 31 and one or more second through pipes 32 or at least two second through pipes 32. The retaining ring 82 is connected between the two sets of grooves 81. Both sets of grooves 81 and the retaining ring 82 have notches aligned with the through groove 7 in the same direction. The notches are used to allow the pressure plate 4 on the probe 2 to move within the through groove 7.

[0047] Both second through pipes 32 are fixed with positioning pieces 9. The positioning pieces 9 have notches aligned with the through grooves 7 and holes that restrict the probe rod 2 to move in one direction. The notches and holes are connected and are used to allow the pressure plate 4 on the probe rod 2 to move through the positioning pieces 9.

[0048] like Figure 6 As shown, and with Figure 6 Taking the screw connector 8 as an example for further explanation, in the figure, the screw connector 8 connects the ends of two second tubes 32 that are both in a cut-off state (to better show the screw connector 8 connected therein). Specifically, one set of grooves 81 is located in the bottom end of the upper second tube 32, and another set of grooves 81 is located in the top end of the upper second tube 32. The grooves 81 are specifically composed of two upper and lower circular flanges spaced at a certain distance. The retaining ring 82 is composed of two flanges and a connecting ring. The distance between the two flanges on the connecting ring is equal to the thickness of the two circular flanges superimposed. Thus, the two flanges of the retaining ring 82 are located between the two flanges of the two sets of grooves 81, and the diameter of the retaining ring 82 is equal to the inner diameter of the tube. This allows the retaining ring 82 to be limited between the two grooves 81, thereby achieving the rotation of one second tube 32 on the other without detaching. With rotation, the through grooves 7 on the tubes are aligned or staggered.

[0049] In some instances, such as Figure 7 As shown, the fixing component 5 includes a first limiting member 51 and a second limiting member 52. Both the first limiting member 51 and the second limiting member 52 include a locking body 53. The two locking bodies 53 are fixed to the bottom of the base 10 in an alternating manner. Both locking bodies 53 are used to engage with the first through tube 31 located at the top. The locking body 53 is elastic and has an opening. The inner diameter of the locking body 53 is the same as the diameter of the first through tube 31. By applying force to expand the opening of the locking body 53, the locking body 53 can wrap around the first through tube 31. When the locking body 53 of the first limiting member 51 is connected to the outside of the first through tube 31, it forms as shown in the figure. Figure 2 The folded shape shown is in a portable form; when the locking body 53 of the second limiting member 52 is connected to the outside of the first through tube 31, it forms as shown in the figure. Figure 1 The unfolded state shown is in the form of work to be tested;

[0050] In some instances, such as Figure 8 As shown, the fixing component 5 includes a first limiting member 51 and a third limiting member 54. The first limiting member 51 has the same structure as the first limiting member 51 in the previous example, as described above. Through the cooperation of the first limiting member 51 and the third limiting member 54, the change from a folded, portable form to an unfolded form ready for testing can be achieved.

[0051] Furthermore, such as Figure 9As shown, the third limiting member 54 includes a frame 541, a screw 542 and two grippers 543. The frame 541 is fixed to the bottom of the base 10. The screw 542 is rotatably connected to the frame 541 and has two threaded sections with opposite helices. The two grippers 543 are respectively threaded to the two threaded sections of the screw 542, and the ends of the two grippers 543 abut against the frame 541.

[0052] The torque transmitted to the screw 542 by the knob causes the screw 542 to rotate on the frame 541. Under the action of the two oppositely spiraled sections of the screw 542, and with the ends of the two grippers 543 abutting against the frame 541, the two grippers 543 do not rotate with the screw 542, but move synchronously in a straight line towards the center, or move synchronously in a straight line to one side respectively. This allows the two grippers 543 to clamp together outside the first through pipe 31, thus fixing the first through pipe 31, or allows the two grippers 543 to detach together from the first through pipe 31, thus releasing the fixation of the first through pipe 31.

[0053] In some embodiments, though not shown in the figures but understood to be true, the number of the third limiting members 54 constructed as described above is two, and the two third limiting members 54 are respectively used for Figure 2 The fold shown is fixed in a portable form-changing configuration, and as... Figure 1 The unfolded state shown is in a fixed switching mode for the work to be detected.
