[0002] In both industry and agriculture, the temperature and humidity of the soil need to be detected before further construction or farming can be carried out. The soil temperature and humidity sensor is a sensor that serves agriculture and is a product of smart agriculture. It can measure the temperature and humidity of the soil. In the prior art, soil temperature and humidity sensors are usually used to detect soil temperature and humidity.

The probe tube includes a plurality of sections of alternately nested heat-conducting metal tubes and heat-insulating PVC tubes, a temperature sensor is arranged in the heat-conducting metal tube, a detection circuit is arranged in the heat-insulating PVC tube, and humidity sensing electrodes are arranged above and below the detection circuit. By integrating the temperature sensing electrode and the humidity sensing electrode into one, the temperature and humidity can be detected and processed at the same time without affecting each other, thereby improving the detection efficiency.

[0004] The soil temperature and humidity sensors in the prior art have some problems in their actual application. When performing temperature and humidity detection on soils at different depths, the sensors need to be inserted into different depths respectively, which is cumbersome to operate. In addition, the sensor probes are easily damaged by collisions with foreign objects such as sand and gravel in the soil layer. At the same time, the sensor probes encounter great resistance during insertion into the soil, which is not conducive to smooth insertion of the probes. Moreover, during multiple soil detections, the sensor probes are exposed to the soil for a long time, and the soil attached to their surface will affect the accuracy of their multiple detections, and will also cause corrosion damage to the probe surface.

[0018] 1. The present invention arranges multiple groups of mounting seats inside the outer cylinder, and each of the multiple groups of mounting seats is provided with a flippable movable seat. The temperature and humidity sensor is slidably arranged inside the movable seat. When the device performs temperature and humidity detection on multiple soil layers, the outer cylinder can be directly inserted into the multiple soil layers.

[0019] 2. The present invention provides a mounting groove on the outer side of the mounting seat, and the mounting groove and one side of the movable seat are both configured as arc structures. The movable seat can fit tightly with the arc surface of the inner wall of the mounting groove when flipped, and the movable seat maintains a fit state with the mounting groove during the flipping process to prevent soil from following the movable seat into the interior of the device and affecting the use of the device, thereby protecting the temperature and humidity sensor probe.

[0020] 3. The present invention provides a flippable sealing cover on the outer side of the outer cylinder. The sealing cover is adapted to and offset from the movable seat. Before and after the device is inserted and tested, the sealing cover and the movable seat are offset, thereby achieving double sealing of the sliding hole on the movable seat to prevent water vapor in the soil from entering the sliding hole and corroding the probe. During the testing process, the movable seat rotates with the mounting seat and overlaps with the sealing cover.

The provision of the sealing cover can effectively improve the internal sealing effect of the device to protect the probe.

[0021] 4. The present invention provides a trencher at one end of the sealing cover so that sand or impurities in the soil can be scraped off before the probe is inserted into the soil, and a narrow channel can be opened for the probe to pass through, thereby preventing the probe from being hit or blocked during the insertion process. The narrow channel opened in advance can reduce the resistance encountered by the probe, so that the probe can be smoothly inserted into the soil for detection. BRIEF DESCRIPTION OF THE DRAWINGS

When detecting multiple soil layers, the multiple groups of temperature and humidity sensors 3 distributed up and down can follow the outer tube 1 to be inserted into soil layers of different depths, and the temperature and humidity of the soil in different soil layers are monitored by inserting the probe of the temperature and humidity sensor 3 into the soil. During the insertion of the device, the temperature and humidity sensor 3 is stored inside the outer tube 1 to avoid the device from colliding with sand and gravel in the soil and damaging the probe of the temperature and humidity sensor 3. During the detection process, the probe of the temperature and humidity sensor 3 can slide out of the device and perform detection. After the detection is completed, the probe of the temperature and humidity sensor 3 slides into the device, and the soil attached to the surface of the probe is scraped off during the sliding of the probe to avoid the soil from being attached to the probe surface for a long time, affecting its subsequent detection accuracy and corroding the probe surface.

[0041] The mounting seat 2 is provided with multiple seats 2 which are rotatable from top to bottom in sequence inside the outer tube 1. The multiple mounting seats 2 are fixedly connected. Two movable seats 21 are rotatably provided inside the mounting seat 2. Both movable seats 21 have cavities 24 inside. After the device is inserted and the detection is completed, the movable seat 21 is flipped into the mounting seat 2 to facilitate the insertion and protection of the device.

[0042] The connecting pin 22 is rotatably disposed on the inner side of the mounting seat 2 and connected to one end of the movable seat 21 .

[0043] There are two mounting grooves 23, which are respectively arranged on the outer wall of the mounting seat 2. The two movable seats 21 are respectively located inside the two mounting grooves 23. The inner wall of one side of the mounting groove 23 and one end of the movable seat 21 are both arranged as arc structures. The movable seat 21 can rotate to the outside of the mounting seat 2 along the inner wall of the arc structure of the mounting groove 23.

[0044] The slide 25 is slidably arranged inside the cavity 24, and one side of the slide 25 is connected to one end of the temperature and humidity sensor 3. It should be noted that a spring is arranged between the other side of the slide 25 and the cavity 24, and the spring is used to reset the slide 25 and the temperature and humidity sensor 3.

[0045] The slider 26 and the slide groove 261 . The slider 26 is fixedly disposed on one side of the slide seat 25 . The slide groove 261 is opened on the inner wall of the cavity 24 and extends to the surface of the movable seat 21 .

[0046] The connecting groove 27 and the arc groove 271, the connecting groove 27 is arranged at the groove mouth of the slide groove 261, two arc grooves 271 are arranged and are respectively located at the inner walls at both ends of the connecting groove 27, the arc groove 271 is divided into a first groove section and a second groove section, and the first groove section is smoothly connected to the second groove section.

[0047] A transmission sleeve 28 is rotatably arranged inside the mounting seat 2, and two transmission arms 281 are arranged on the outer wall of the transmission sleeve 28, and one end of the two transmission arms 281 can be slidably arranged in the connecting groove 27, and a guide rod 282 is fixedly arranged at one end of the transmission arm 281, and the guide rod 282 is slidably arranged in the arc groove 271, and a protrusion 283 is fixedly arranged in the middle part of one end of the transmission arm 281, and the protrusion 283 is slidably arranged in the slide groove 261, and one end of the protrusion 283 is fitted with the slide seat 25, and the transmission sleeve 28 and the transmission arm 281 are used to push the movable seat 21 to flip and push the probe of the temperature and humidity sensor 3 out of the movable seat 21.

[0048] It should be noted that when the guide rod 282 slides along the first groove section, the movable seat 21 will flip outward, and during this process, the probe of the temperature and humidity sensor 3 will not extend to the outside of the movable seat 21. When the guide rod 282 slides along the second groove section, the movable seat 21 will no longer flip and be fixed at the current position, and during this process, the probe of the temperature and humidity sensor 3 will extend from the movable seat 21 and insert into the soil.

[0049] The fixing sleeve 284 is fixedly disposed inside the mounting seat 2 , and the transmission sleeve 28 is rotatably disposed at the middle portion of the outer side of the fixing sleeve 284 .

[0050] The rotating shaft 285 is rotatably disposed inside the fixed sleeve 284 , and an extension arm 286 is fixedly disposed on the outer wall of the rotating shaft 285 , and a connecting block 287 is rotatably disposed on one end of the extension arm 286 through a pin shaft, and the connecting block 287 is fixedly disposed on the inner wall of the transmission sleeve 28 .

[0051] There are two limit grooves 288, both of which are arranged on the outer wall of the fixing sleeve 284. The connecting block 287 is slidably arranged in the limit groove 288. The limit groove 288 is used to limit the sliding range of the connecting block 287 to limit the flipping range of the movable seat 21 to prevent it from being separated from the installation groove 23 and causing soil to enter the interior of the device.

[0052] The temperature and humidity sensor 3 is slidably arranged inside the cavity 24. One end of the cavity 24 is provided with a sliding hole extending to the outer surface of the mounting seat 2. The probe of the temperature and humidity sensor 3 is slidably arranged in the sliding hole. The temperature and humidity sensor 3 can slide in the cavity 24 so that its probe slides out of the mounting seat 2 and is inserted into the soil layer. It should be noted that the gap between the sliding hole and the probe of the temperature and humidity sensor 3 is small. Without affecting the sliding of the probe, the soil attached to the surface of the probe can be prevented from entering the sliding hole.

[0053] The end cover 4 is an annular structure and is fixedly disposed on the top end of the outer cylinder 1 .

[0054] There are two positioning grooves 41 , both of which are opened on the lower surface of the end cover 4 , and the positioning grooves 41 are designed as an arc structure.

[0055] The transmission rod 42 is provided with two and can be slid in two positioning grooves 41 respectively. The two transmission rods 42 are fixedly arranged on the upper surface of the uppermost mounting seat 2. The transmission rod 42 is used to drive the mounting seat 2 to rotate.

[0056] The driving rod 43 is fixedly disposed on the top of the uppermost rotating shaft 285 . The driving rod 43 is used to drive the rotating shaft 285 to rotate so as to drive the movable seat 21 to flip.

[0057] The transmission seat 421 is configured as an annular structure and is located at the top end of the transmission rod 42 . The transmission seat 421 is rotatably disposed inside the end cover 4 .

[0058] There are two drive motors 44, which are fixed inside the end cover 4. The two drive motors 44 are respectively connected to the transmission base 421 and the drive rod 43 through a gear set. It should be noted that the drive motor 44 is used to provide power for the transmission base 421 and the drive rod 43. It has a matching control panel and power supply, and the models of the control panel and the power supply are not limited without affecting its operation.

[0059] A numerical control display is provided on the outside of the outer tube 1, and the numerical control display is connected to the temperature and humidity sensor 3 signal. The numerical control display is used to display the monitoring data of the temperature and humidity sensor 3. The numerical control display adopts a model available on the market, which has a communication function matching the wireless communication module in the temperature and humidity sensor 3. It can realize a wireless signal connection with the temperature and humidity sensor 3. The numerical control display is a prior art and will not be described in detail here, nor is it shown in the figure.

[0060] The temperature and humidity sensor 3 includes a sensor body, a wireless communication module, a power module and a probe. The temperature and humidity sensor 3 is connected to the CNC display by signal. It should be noted that the temperature and humidity sensor 3 adopts a model available on the market. It adopts a matching wireless communication module and a power module, and both the wireless communication module and the power module adopt models available on the market. There is no restriction on the model without affecting the operation of the temperature and humidity sensor 3.

[0061] When using a multi-soil layer soil temperature and humidity detector of the present embodiment, the outer tube 1 drives multiple sets of mounting seats 2 and temperature and humidity sensors 3 to be inserted into the soil, so that the multiple sets of mounting seats 2 and temperature and humidity sensors 3 are respectively inserted into the soil of different soil layers. During this process, the movable seat 21 inside the mounting seat 2 is received in the mounting groove 23, and the probe of the temperature and humidity sensor 3 is received in the movable seat 21.

[0062] When conducting soil temperature and humidity detection, a hole can be first punched at the position to be tested, and then the outer cylinder 1 can be inserted into the hole. The driving motor 44 is controlled to start so that the driving rod 43 rotates, and the driving rod 43 drives the rotating shaft 285 to rotate. The rotating shaft 285 drives the transmission sleeve 28 to rotate through the extension arm 286 and the connecting block 287. The transmission sleeve 28 drives the transmission arm 281 on its outer side to move, and the transmission arm 281 drives the guide rod 282 to slide along the first groove section of the arc groove 271. Through the cooperation between the guide rod 282 and the first groove section, the movable seat 21 is pushed to rotate around the connecting pin 22, so that the movable seat 21 is flipped out of the installation groove 23.

[0063] When the transmission sleeve 28 rotates a certain angle, that is, the guide rod 282 moves to the end of the first groove section, a part of the movable seat 21 flips to the outside of the mounting groove 23. At this time, the sliding hole on the surface of the movable seat 21 rotates to the outside of the mounting groove 23, and the protrusion 283 at one end of the transmission arm 281 contacts one end of the slide 25. At this time, the transmission sleeve 28 continues to rotate to make the guide rod 282 move along the second groove section. At this time, the protrusion 283 continues to squeeze the slide 25, so that the slide 25 continues to drive the temperature and humidity sensor 3 to slide, and the probe of the temperature and humidity sensor 3 extends from the sliding hole and is inserted into the soil outside the movable seat 21.

[0064] The temperature and humidity sensor 3 can obtain the temperature and humidity information of the soil through the probe, and transmit the information to the CNC display for display, so as to complete the detection of temperature and humidity in multiple soil layers.

[0065] After the detection is completed, the driving motor 44 is controlled to reverse so that the rotating shaft 285 reverses, and the rotating shaft 285 drives the transmission sleeve 28 and the transmission arm 281 to flip, so that the extrusion of the slide 25 by the protrusion 283 at one end of the transmission arm 281 is released. At this time, the slide 25 can drive the temperature and humidity sensor 3 to slowly reset under the action of the spring. When the transmission sleeve 28 rotates a certain angle, the probe of the temperature and humidity sensor 3 completely enters the slide hole. At this time, the transmission sleeve 28 continues to rotate and drives the movable seat 21 to flip through the transmission arm 281 and the guide rod 282 until the movable seat 21 completely enters the installation groove 23. At this time, the movable seat 21 and the probe of the temperature and humidity sensor 3 can be stored. In this process, the soil attached to the surface of the probe of the temperature and humidity sensor 3 is scraped off by the groove of the slide hole to avoid the soil from adhering to the probe surface for a long time and affecting its detection accuracy and the top view of the probe surface.

[0066] By using the mounting seat 2, the movable seat 21 and the sliding hole in coordination, during the process of inserting the outer cylinder 1 into the soil hole, the movable seat 21 is received in the mounting seat 2, and the probe of the temperature and humidity sensor 3 is received in the movable seat 21, so as to prevent the probe from being damaged by collision during the process of inserting the outer cylinder 1 into the soil hole. After the outer cylinder 1 is inserted into the soil hole, the movable seat 21 is turned outward from the mounting seat 2 and abuts against the inner wall of the hole, so as to limit and fix the outer cylinder 1 as a whole, ensuring the stability of the entire device during the process of inserting the probe into the soil for temperature and humidity detection, thereby ensuring the accuracy of the detection. After completing the temperature and humidity detection, the probe slides back into the movable seat 21 along the sliding hole. At this time, the sliding hole can scrape off the soil attached to the surface of the probe, so as to prevent the soil from adhering to the surface of the probe for a long time and affecting its accuracy.

[0067] Embodiment 2

[0068] like Figure 11 to Figure 12 As shown, this embodiment further improves the present application on the basis of the first embodiment. Considering the presence of water vapor in the soil, the water vapor can enter the sliding hole through the gap between the movable seat 21 and the mounting groove 23, thereby corroding the probe surface of the temperature and humidity sensor 3. In order to better protect the probe of the temperature and humidity sensor 3, in this embodiment, it includes:

[0069] The sealing cover 12 is provided with two sets of reversible ones which are arranged on the outer surface of the outer cylinder 1. The sealing cover 12 is adapted to the outer surface of the movable seat 21, and the sealing cover 12 and the movable seat 21 are staggered. When the mounting seat 2 drives the movable seat 21 to rotate to coincide with the sealing cover 12, the movable seat 21 can drive the sealing cover 12 to flip outward. When the sealing cover 12 and the movable seat 21 are misaligned, the movable seat 21 can be sealed and protected. It should be noted that the connection between the sealing cover 12 and the outer cylinder 1 is set as an arc structure. The design of the arc structure enables the sealing cover 12 to flip outward with the movable seat 21 without being interfered by the outer cylinder 1.

[0070] The dovetail groove 291 and the dovetail block 292, the dovetail groove 291 is set as an annular structure and is arranged in the middle of the outer side surface of the mounting seat 2 and the movable seat 21, the dovetail block 292 is provided with multiple groups and is respectively arranged on the inner side surface of the outer tube 1 and the sealing cover 12, and the movable seat 21 can be connected with the sealing cover 12 through the dovetail groove 291 and the dovetail block 292.

[0071] The outer side of the sealing cover 12 may be configured as a conical structure so that the movable seat 21 can drive the sealing cover 12 to rotate outwards for flipping.

[0072] In this embodiment, when the device is inserted into the soil, the movable seat 21 and the sealing cover 12 are in a misaligned state. At this time, two layers of seals are formed between the connection between the sealing cover 12 and the outer tube 1 and between the movable seat 21 and the mounting groove 23, which can effectively prevent water vapor in the soil from entering the sliding hole and corroding the probe surface.

[0073] When the device is inserted into the soil for detection, the driving motor 44 is first controlled to rotate, so that the transmission seat 421 drives the transmission rod 42 to rotate, the transmission rod 42 drives the mounting seat 2 to rotate, and the mounting seat 2 drives the movable seat 21 to rotate. When the transmission rod 42 rotates to one end of the positioning groove 41, the movable seat 21 completely overlaps with the sealing cover 12. At this time, the movable seat 21 is controlled to flip outward, and the movable seat 21 can drive the sealing cover 12 to flip outward, and subsequent detection work is performed.

[0074] During this process, the dovetail block 292 on the inner side of the sealing cover 12 slides into the dovetail groove 291 on the outer side of the mounting seat 2 and the movable seat 21 successively, and the mounting seat 2 and the movable seat 21 respectively limit the sealing cover 12 through the dovetail groove 291 and the dovetail block 292 to prevent the sealing cover 12 from falling off.

[0075] The device is sealed by providing a sealing cover 12 to prevent water vapor in the soil from entering the inside of the device, thereby improving the protection effect of the temperature and humidity sensor 3 and increasing the service life of the temperature and humidity sensor 3.

[0076] Embodiment 3

[0077] like Figure 5 and Figure 6 As shown, this embodiment further improves the present application on the basis of the second embodiment. Considering the presence of sand and other impurities in the soil, the probe may be hit or blocked during the extension process, and the soil at some locations to be tested is pressed hard, and the resistance encountered by the probe during the insertion of the soil is large. Therefore, in order to enable the probe of the temperature and humidity sensor 3 to be inserted into the soil more smoothly, in this embodiment, it includes:

[0078] There are two furrow openers 121, which are fixedly disposed at one end of the corresponding sealing cover 12. The furrow opener 121 is in the same height as the corresponding probe, and the thickness of the furrow opener 121 is smaller than the diameter of the probe.

[0079] The groove 122 is formed on the outer wall of the outer cylinder 1 and can accommodate the trench opener 121 .

[0080] In the process of the movable seat 21 driving the sealing cover 12 to flip outward, the trench opener 121 scrapes off the sand or impurities in its movement path and opens a fan-shaped narrow channel on the movement path. It should be noted that since the thickness of the trench opener 121 is smaller than the diameter of the probe, the height of the narrow channel is also smaller than the diameter of the probe. After the probe is inserted into the soil through the narrow channel, it can still be in close contact with the surrounding soil, thereby effectively detecting the temperature and humidity of the soil. In the process of the probe gradually inserting into the soil after the movable seat 21 flips into place, the probe is inserted into the soil through the narrow channel opened by the trench opener 121.

[0081] By arranging a trencher 121 at one end of the sealing cover 12, the sand and impurities in the soil can be scraped off before the probe is inserted into the soil, and a narrow channel for the probe to pass through can be opened, so as to avoid the probe from being hit and blocked during the insertion process. The narrow channel opened in advance can reduce the resistance encountered by the probe, so that the probe can be smoothly inserted into the soil for detection.

[0082] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
