Description

Technical Field

[0001] The present invention relates to the technical field of soil detection devices, and particularly relates to a multi-layer soil temperature and humidity detector. Background Art

[0002] In both industry and agriculture, it is necessary to detect the temperature and humidity of the soil in order to further carry out construction or farming. A soil temperature and humidity sensor is a sensor serving agriculture and a product of smart agriculture, which can measure the temperature and humidity of the soil. In the prior art, soil temperature and humidity sensors are usually used to detect the soil temperature and humidity.

[0003] In the prior art, for example, a soil temperature and humidity sensor for field planting with the publication number CN106017567A includes a probe tube. A rotating handle is connected to the top end of the probe tube. A rotary sleeve is arranged at the center of the rotating handle. An internal thread is provided in the central hole of the rotary sleeve, and the internal thread is screwed and fixed with the external thread on the side wall of the top end of the probe tube. A spiral conical drill bit is arranged at the bottom end of the probe tube. The probe tube includes a plurality 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, the temperature and humidity can be detected and processed simultaneously without mutual influence, improving the detection efficiency.

[0004] There are some problems in the actual application of the soil temperature and humidity sensors in the prior art. When detecting the temperature and humidity of the soil in different depth soil layers, the sensors need to be inserted into different depths respectively, and the operation is cumbersome. Moreover, 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 will encounter greater resistance during the process of inserting into the soil, which is not conducive to the smooth insertion of the probes. In addition, during the process of detecting the soil multiple times, the sensor probes are exposed in the soil for a long time, and the soil attached to their surfaces will affect the accuracy of multiple detections, and at the same time, it will also cause corrosion and damage to the probe surfaces.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention sets multiple groups of mounting seats inside the outer cylinder. Each of the multiple groups of mounting seats is provided with a movable seat that can be flipped. The temperature and humidity sensor is slidably arranged inside the movable seat. When the device detects the temperature and humidity of multi-layer soil, the outer cylinder can be directly inserted into the multi-layer soil. During the insertion process, the movable seat is received inside the mounting seat, which can prevent the probes of the temperature and humidity sensor inside the movable seat from being damaged by the collision of sand and gravel in the soil during the insertion process. Before and after the detection, the probes of the temperature and humidity sensor can slide along the sliding holes on the movable seat, so that the soil attached to the surface of the probes is scraped off by the sliding holes, avoiding the soil attaching to the surface of the probes and affecting the subsequent detection accuracy, and also avoiding the surface corrosion and damage of the probes caused by the long-term attachment of the soil to the surface of the probes.

[0019] 2. The present invention sets a mounting groove on the outer side of the mounting seat. The mounting groove and one side of the movable seat are both set as arc-shaped structures. When the movable seat flips, it can closely fit with the arc-shaped surface of the inner wall of the mounting groove, and the movable seat maintains the fitting state with the mounting groove during the flipping process, so as to prevent the soil from entering the device along with the movable seat and affecting the use of the device, thereby playing a protective role for the probes of the temperature and humidity sensor.

[0020] 3. The present invention sets a flipable sealing cover on the outer side of the outer cylinder. The sealing cover is adapted to and misaligned with the movable seat. Before and after the device is inserted and during the detection, the sealing cover and the movable seat are misaligned, which can achieve double sealing of the sliding holes on the movable seat to prevent the water vapor in the soil from entering the sliding holes and corroding the probes. During the detection process, the movable seat rotates with the mounting seat and coincides with the sealing cover. At this time, the sealing cover can flip outwards along with the movable seat to ensure the smooth sliding out of the probes and the smooth progress of the detection work. The setting of the sealing cover can effectively improve the internal sealing effect of the device to achieve the effect of protecting the probes.

[0021] 4. The present invention sets a ditch opener at one end of the sealing cover, so as to scrape the sand or impurities in the soil in advance before the probes are inserted into the soil and open a narrow channel for the probes to pass through, thereby avoiding the collision and obstruction of the probes during the insertion process, and the pre-opened narrow channel can reduce the resistance received by the probes, so as to facilitate the probes to smoothly insert into the soil for detection.

[0048] It should be noted that when the guide rod 282 slides along the first groove section, the movable seat 21 will turn outwards, and during this process, the probe of the temperature and humidity sensor 3 will not extend outside the movable seat 21. When the guide rod 282 slides along the second groove section, the movable seat 21 will no longer turn over and is fixed at the current position, and during this process, the probe of the temperature and humidity sensor 3 extends out of the movable seat 21 and inserts into the soil.

[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 supply module, and a probe. The temperature and humidity sensor 3 is signal-connected to the numerical control display. It should be noted that the temperature and humidity sensor 3 uses a commercially available model, which is equipped with a supporting wireless communication module and power supply module, and both the wireless communication module and the power supply module use commercially available models. Without affecting the operation of the temperature and humidity sensor 3, its model is not restricted.

[0061] When using a multi-layer soil temperature and humidity detector according to this embodiment, the outer cylinder 1 drives multiple sets of mounting seats 2 and the temperature and humidity sensor 3 to be inserted into the soil, so that multiple sets of mounting seats 2 and the temperature and humidity sensor 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 performing soil temperature and humidity detection, a hole can be drilled at the position to be measured first, and then the outer cylinder 1 is inserted into the hole. By controlling the driving motor 44 to start, the driving rod 43 rotates, 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-shaped groove 271. Through the cooperation of 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 flips out of the mounting groove 23.

[0063] When the transmission sleeve 28 rotates a certain angle, that is, when 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 convex block 283 at one end of the transmission arm 281 contacts one end of the sliding seat 25. At this time, continue to rotate the transmission sleeve 28 to make the guide rod 282 move along the second groove section. At this time, the convex block 283 continues to squeeze the sliding seat 25, so that the sliding seat 25 continues to drive the temperature and humidity sensor 3 to slide, and the probe of the temperature and humidity sensor 3 extends out of 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 numerical control display for display to complete the detection of the temperature and humidity in the multi-layer soil.

[0065] After the detection is completed, the driving motor 44 is controlled to reverse, so that the rotating shaft 285 reverses. The rotating shaft 285 drives the transmission sleeve 28 and the transmission arm 281 to turn over, so that the extrusion of the convex block 283 at one end of the transmission arm 281 on the sliding seat 25 is released. At this time, the sliding seat 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 sliding hole. At this time, the transmission sleeve 28 continues to rotate, and drives the movable seat 21 to turn over 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 storage of the movable seat 21 and the probe of the temperature and humidity sensor 3 can be completed. During this process, the soil attached to the surface of the probe of the temperature and humidity sensor 3 is scraped off at the notch of the sliding hole, so as to avoid the long-term attachment of soil to the probe surface affecting its detection accuracy and looking down at the probe surface.

[0066] By using the cooperation of the mounting seat 2, the movable seat 21 and the sliding hole, during the process of inserting the outer cylinder 1 into the soil hole, the movable seat 21 is stored in the mounting seat 2, and the probe of the temperature and humidity sensor 3 is stored in the movable seat 21, so as to avoid the probe being damaged by collision during the process of inserting the outer cylinder 1 into the soil hole. When the outer cylinder 1 is inserted into the soil hole, the movable seat 21 turns outwards from the mounting seat 2 and abuts against the inner wall of the hole, so as to limit and fix the whole outer cylinder 1, ensuring the stability of the whole device during the process of inserting the probe into the soil for temperature and humidity detection, and thus ensuring the accuracy of the detection. After the temperature and humidity detection is completed, 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, avoiding the long-term attachment of soil to the probe surface and affecting its accuracy.

[0067] Embodiment 2

[0068] As Figures 11 to 12 shown, this embodiment further improves the present application on the basis of Embodiment 1. Considering that there is water vapor in the soil, the water vapor can enter the sliding hole through the gap between the movable seat 21 and the installation groove 23, thus corroding the surface of the probe 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] Sealing covers 12, there are two groups of them and they are both rotatably arranged on the outer surface of the outer cylinder 1. The sealing covers 12 are adapted to the outer surface of the movable seat 21, and the sealing covers 12 and the movable seat 21 are arranged in a staggered manner. When the mounting seat 2 drives the movable seat 21 to rotate to coincide with the sealing covers 12, the movable seat 21 can drive the sealing covers 12 to turn outwards. When the sealing covers 12 and the movable seat 21 are in a staggered position, the sealing protection of the movable seat 21 can be realized. It should be noted that the connections between the sealing covers 12 and the outer cylinder 1 are all designed as arc-shaped structures. The design of the arc-shaped structures enables the sealing covers 12 to turn outwards following 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 arranged in an annular structure and is arranged in the middle of the outer side surfaces of the mounting seat 2 and the movable seat 21. There are multiple groups of dovetail blocks 292 which are respectively arranged on the inner side surfaces of the outer cylinder 1 and the sealing cover 12. The movable seat 21 can be connected to the sealing cover 12 through the dovetail groove 291 and the dovetail block 292.

[0071] The outer side of the sealing cover 12 can be arranged in a conical structure so as to facilitate the movable seat 21 to drive the sealing cover 12 to rotate outward for flipping.

[0072] In this embodiment, during the process of inserting the device 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 at the connection between the sealing cover 12 and the outer cylinder 1 and between the movable seat 21 and the installation groove 23, which can effectively prevent the water vapor in the soil from entering the sliding hole and corroding the surface of the probe.

[0073] When the device is inserted into the soil for detection, first control the driving motor 44 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 and the sealing cover 12 completely coincide. At this time, control the movable seat 21 to flip outward. The movable seat 21 can drive the sealing cover 12 to flip outward and perform subsequent detection work.

[0074] During this process, the dovetail blocks 292 on the inner side of the sealing cover 12 slide into the dovetail grooves 291 on the outer sides of the mounting seat 2 and the movable seat 21 in sequence. 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] By arranging the sealing cover 12 to seal the device, it is avoided that the water vapor in the soil enters the device interior, thereby improving the protection effect on the temperature and humidity sensor 3 and increasing the service life of the temperature and humidity sensor 3.

[0076] Embodiment Three

[0077] As Figure 5 and Figure 6 shown, this embodiment further improves this application on the basis of Embodiment Two. Considering that there are sand and other impurities in the soil, the probe may be collided or obstructed during the extending process, and the soil at some measurement locations is relatively compacted, and the resistance of the probe during the insertion process into the soil is relatively large. Therefore, in order for the probe of the temperature and humidity sensor 3 to be inserted into the soil more smoothly, in this embodiment, it includes:

[0078] Two furrow openers 121, which are fixedly arranged at one end of the corresponding sealing cover 12. The furrow openers 121 are at the same height as the corresponding probes, and the thickness of the furrow openers 121 is less than the diameter of the probe.

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

[0080] During the process of the movable seat 21 driving the sealing cover 12 to turn outwards, the furrow opener 121 scrapes the sand or impurities existing 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 furrow opener 121 is smaller than the diameter of the probe, the height of this 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, so as to effectively detect the temperature and humidity of the soil. During the process of the probe gradually inserting into the soil after the movable seat 21 turns in place, the probe is inserted into the soil through the narrow channel opened by the furrow opener 121.

[0081] By arranging the furrow opener 121 at one end of the sealing cover 12, the sand or impurities in the soil are scraped in advance before the probe is inserted into the soil, and a narrow channel for the probe to pass through is opened, so as to avoid the probe being collided and blocked during the insertion process, and the pre-opened narrow channel can reduce the resistance received 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 are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
