Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-6 One embodiment provided by this utility model:
[0024] A passive soil temperature and humidity measuring instrument includes a temperature and humidity measuring instrument body 1.

Two sets of probe bodies 12 are provided. A protective mechanism is provided on the surface of the temperature and humidity measuring instrument body 1. The protective mechanism includes a slider 2, which is slidably connected to the surface of the temperature and humidity measuring instrument body 1. A protective shell 21 is fixedly connected to the surface of the slider 2. A first spring 22 is fixedly connected to the surface of the protective shell 21. A protective top plate 23 is fixedly connected to the surface of the first spring 22. The protective top plate 23 is slidably connected to the protective shell 21. On the surface, a limiting rod 24 is slidably connected to the side of the protective shell 21. A connecting plate 25 is fixedly connected to the surface of the limiting rod 24. A second spring 26 is fixedly connected to the surface of the connecting plate 25. The end of the second spring 26 away from the connecting plate 25 is fixedly connected to the surface of the protective shell 21. A limiting hole 27 is opened on the surface of the temperature and humidity measuring instrument body 1. This protective mechanism can provide a protective shield for the probe body 12 through the protective shell 21 when the probe body 12 is not in use, so as to prevent the probe body 12 from bending and deforming during the carrying process, thereby ensuring the measurement accuracy of the passive soil temperature and humidity measuring instrument.
[0025] Furthermore, an adjustment mechanism is provided on the surface of the temperature and humidity measuring instrument body 1. The adjustment mechanism includes a support block 3, which is fixedly connected to the bottom of the temperature and humidity measuring instrument body 1. A bidirectional screw 31 is rotatably connected to the surface of the support block 3. A knob 32 is fixedly connected to one end of the bidirectional screw 31. A square nut 33 is threadedly connected to the surface of the knob 32. The square nut 33 is fixedly connected to the bottom of the probe connector 11. This adjustment mechanism can adjust the distance between the two sets of probe bodies 12. By adjusting the distance between the two sets of probe bodies 12, it can better adapt to different detection needs and improve the adaptability of the passive soil temperature and humidity measuring instrument.
[0026] Furthermore, the temperature and humidity measuring instrument body 1 has grooves on both sides, and the grooves are in the shape of a "T". The slider 2 slides on the groove of the temperature and humidity measuring instrument body 1 in the shape of a "T". The protective shell 21 slides on the surface of the temperature and humidity measuring instrument body 1 via the slider 2. The length of the protective shell 21 is longer than the length of the probe body 12, so that the protective shell 21 can completely cover the probe body 12. When not in use, the protective shell 21 can be retracted on the surface of the temperature and humidity measuring instrument body 1, so as not to occupy the space for use.
[0027] Furthermore, a guide hole is provided on the surface of the protective shell 21, and the protective top plate 23 slides on the guide hole of the protective shell 21. The protective top plate 23 is in an "L" shape. Multiple sets of first springs 22 are provided. The elastic force of the first springs 22 acts on the protective top plate 23. The protective top plate 23 cooperates with the protective shell 21 at the top to block the top of the probe body 12. Moreover, by moving, the protective top plate 23 can ensure that the protective top plate 23 and the probe body 12 do not come into contact with each other during the movement of the protective shell 21.
[0028] Furthermore, a circular hole is provided on one side of the protective shell 21, and the limiting rod 24 slides on the circular hole of the protective shell 21.

The limiting rod 24 restricts the position of the protective shell 21 on the temperature and humidity measuring instrument body 1 through the limiting hole 27. The two sets of limiting holes 27 correspond to the retracted and unfolded positions of the protective shell 21, respectively, which facilitates the precise adjustment of the position of the protective shell 21 on the temperature and humidity measuring instrument body 1.
[0029] Furthermore, a guide groove is provided on the surface of the temperature and humidity measuring instrument body 1. The probe connector 11 slides on the guide groove of the temperature and humidity measuring instrument body 1, and the probe body 12 slides horizontally on the surface of the temperature and humidity measuring instrument body 1 through the probe connector 11, thereby changing the distance between the two sets of probe bodies 12 on the temperature and humidity measuring instrument body 1. A soil temperature and humidity sensor is installed inside the temperature and humidity measuring instrument body 1, and the probe connector 11 is connected to the soil temperature and humidity sensor through a connecting wire. A wiring hole is provided on one side of the guide groove of the temperature and humidity measuring instrument body 1, and the wiring hole is connected to the interior of the temperature and humidity measuring instrument body 1, ensuring that the probe connector 11 can always be connected to the soil temperature and humidity sensor through the connecting wire during the movement. A guide hole is provided at the bottom of the guide groove of the temperature and humidity measuring instrument body 1, and the square nut 33 slides on the guide hole of the temperature and humidity measuring instrument body 1. The square nut 33 will slide synchronously with the probe connector 11.
[0030] Furthermore, the bidirectional screw 31 drives the square nut 33 to slide on the guide hole of the temperature and humidity measuring instrument body 1 by rotation. There are two sets of square nuts 33, and the sliding directions of the two sets of square nuts 33 are opposite. The square nut 33 drives the probe body 12 to slide horizontally on the surface of the temperature and humidity measuring instrument body 1 through the probe connector 11, thereby changing the horizontal distance between the two sets of probe bodies 12.
[0031] Working principle: Pull the protective top plate 23 on the surface of the protective shell 21 so that the bottom of the protective top plate 23 is higher than the horizontal height of the probe body 12. Then, slide the protective shell 21 on the surface of the temperature and humidity measuring instrument body 1 via the slider 2, so that the protective shell 21 slides away from the side of the temperature and humidity measuring instrument body 1. Release the protective top plate 23, and under the elastic force of the first spring 22, the protective top plate 23 descends to its original position. At this time, the elastic force of the second spring 26 acts on the limiting rod 24 through the connecting plate 25, so that the limiting rod 24 slides on the circular hole of the protective shell 21 until it is inserted into the limiting hole 27. The limiting rod 24 restricts the position of the protective shell 21 through the limiting hole 27, so that the protective shell 21, together with the protective top plate 23, protects the probe body 12 and prevents the probe body 12 from bending and deforming during the carrying process, thereby ensuring the measurement accuracy of the passive soil temperature and humidity measuring instrument.
[0032] The double-ended screw 31 is driven to rotate on the support block 3 by the knob 32. The double-ended screw 31 drives the square nut 33 to slide on the guide hole of the temperature and humidity measuring instrument body 1 by rotation. The two sets of square nuts 33 slide in opposite directions. The two sets of square nuts 33 drive the probe connector 11 to slide on the guide groove of the temperature and humidity measuring instrument body 1, thereby changing the distance between the two sets of probe bodies 12. By adjusting the distance between the two sets of probe bodies 12, it can better adapt to different detection needs and improve the adaptability of the passive soil temperature and humidity measuring instrument.
