Technical Field
[0001] The utility model relates to the technical field of moisture measurement, and particularly relates to a handheld soil moisture measurement device. Background Art
[0002] Soil moisture content is an important factor affecting agricultural production. Generally speaking, soil moisture content refers to the water content in the soil. Water is an essential substance for crop growth. In agriculture, irrigation work is often required to supplement soil moisture. Soil moisture measuring instruments can measure the water content in the soil, which is of great significance for guiding agricultural production and ecological environment protection.
[0003] A handheld soil moisture measurement device is disclosed in the Chinese utility model patent with the publication number CN217688940U, which includes a housing with an upper opening at the top and a lower opening at the bottom; a clamp is arranged inside the housing; a soil moisture measuring instrument, the moisture sensor of the soil moisture measuring instrument is placed inside the clamp, and the sensor probe of the moisture sensor extends outside the lower opening; a pull rod, the inner end of the pull rod is connected to the clamp, and the outer end extends outside the upper opening, and the clamp clamps the moisture sensor of the soil moisture measuring instrument. The advantages of the utility model are that the HM-EC type moisture sensor is installed inside the device, and the sensor probe is inserted into soil layers at different depths by adjusting the position of the knob on the device to complete the measurement of the water content. After the measurement is completed, the sensor probe is retracted into the device by pulling the pull rod at the top. A brush is installed at the bottom of the device to remove the soil sticking to the sensor probe; in addition, the longitude and latitude acquisition device can display and save the longitude and latitude of the acquisition point in real time and output data through the USB interface.
[0004] In view of the above related technologies, the inventor believes that there are the following defects: the above device drives the outer shell by driving the knob, and then adjusts the position of the sensor probe. However, in the actual use process, since multiple depth adjustment holes are directly communicated with the inner cavity of the housing, during the measurement by the staff, dirt and other impurities are likely to move into the housing, which is likely to interfere with the measurement results. Content of the Utility Model
[0005] In order to solve the above problems, the utility model provides a handheld soil moisture measurement device.
[0006] The above technical object of the utility model is achieved by the following technical solutions: A handheld soil moisture measuring device includes a hollow shell, a moisture sensor disposed inside the shell, a sensor probe interconnected with the moisture sensor, and a moisture detector interconnected with the moisture sensor. A fixing groove is formed on the inner wall of the shell, a fixing block is slidably disposed in the fixing groove, and the fixing block is fixed to the moisture sensor. A limiting groove is formed on the inner wall of the shell, and a limiting component for limiting the moisture sensor is disposed on the shell.
[0007] By adopting the above technical solutions, when the staff needs to measure the moisture of the soil, the staff needs to adjust the position of the sensor probe. At this time, the staff needs to turn off the limiting component, and then the moisture sensor can move to the highest point under the action of the stabilizing spring. Further, the staff needs to pull down the sensor probe to adjust the position of the sensor probe. When the staff stops moving the sensor probe, the sensor probe is kept stable under the combined action of the stabilizing spring and the limiting component, thereby reducing the operation difficulty of the staff and decreasing the probability of soil entering the shell.
[0008] Further, the limiting component includes a limiting plate slidably disposed in the limiting groove, a limiting spring with one end fixed to the side wall of the limiting plate away from the moisture sensor, a plurality of first limiting blocks evenly distributed on the side wall of the limiting plate, and a second limiting block fixed to the side wall of the moisture sensor. A first inclined surface is formed on the edge where the side wall of the first limiting block away from the limiting plate intersects with its upper surface, and a second inclined surface matching the first inclined surface is formed on the side wall of the second limiting block close to the limiting plate. The other end of the limiting spring is fixed to the inner wall of the limiting groove away from the moisture sensor.
[0009] Further, a stabilizing spring is fixed to the upper surface of the moisture sensor, and the other end of the stabilizing spring is fixed to the inner top wall of the shell.
[0010] By adopting the above technical solutions, when the moisture sensor is not subjected to external force, the moisture sensor continuously receives the upward acting force of the stabilizing spring and remains stable. When the staff needs to adjust the position of the sensor probe, the staff needs to slide the limiting plate, and then the moisture sensor can move to the highest point. Subsequently, the staff only needs to release the limiting plate and pull down the sensor probe to adjust the position of the sensor probe. When the sensor probe moves to a suitable position, the staff only needs to release the sensor probe, and then the second limiting block can be pressed against one of the first limiting blocks, thereby keeping the sensor probe stable, thus reducing the operation difficulty of the staff. Subsequently, the staff only needs to connect the sensor probe with the soil, and then the moisture of the soil can be measured by the moisture detector.
[0011] Further, a connecting rope is fixed to the side wall of the limiting plate away from the first limiting block, and the other end of the connecting rope extends outside the housing and is slidably connected.
[0012] By adopting the above technical solution, when the staff needs to slide the limiting plate, the staff only needs to pull the connecting rope, and the limiting plate can follow the movement of the connecting rope, thereby reducing the difficulty for the staff to move the limiting plate.
[0013] Further, the connecting rope is a connecting rope made of rubber band.
[0014] Further, a connecting block is fixed to the end of the connecting rope.
[0015] By adopting the above technical solution, when the connecting rope is not subjected to external force, the connecting block abuts against the side wall of the housing under the action of the connecting rope, so as to keep the connecting block stable, thereby reducing the probability of the connecting rope being lost.
[0016] Further, moving grooves are formed on both sides of the bottom surface of the housing, moving blocks are slidably arranged in the moving grooves, and cleaning blocks for cleaning the sensor probes are fixed to the bottom surfaces of the moving blocks.
[0017] Further, silica gel sheets are arranged on the side walls of the two cleaning blocks close to each other.
[0018] By adopting the above technical solution, after the sensor probe measures the soil, the staff needs to separate the sensor probe from the soil and reset the sensor probe. At this time, the staff only needs to slide the two moving blocks, and the two silica gel sheets can abut against the sensor probe, so that the silica gel sheets clean the sensor probe, thereby reducing the operation difficulty for the staff.
[0019] In summary, the utility model has the following beneficial effects:
[0020] 1. In this application, when the staff needs to measure the moisture of the soil, the staff needs to adjust the position of the sensor probe. At this time, the staff needs to turn off the limiting component, and the moisture sensor can move to the highest point under the action of the stable spring. Further, the staff needs to pull the sensor probe downward to adjust the position of the sensor probe. When the staff stops moving the sensor probe, the sensor probe is kept stable under the combined action of the stable spring and the limiting component, thereby reducing the operation difficulty for the staff and reducing the probability of soil entering the housing;
[0021] 2. In this application, when the moisture sensor is not subjected to external force, the moisture sensor continuously receives an upward force from the stable spring and remains stable. When the staff needs to adjust the position of the sensor probe, the staff only needs to slide the limit plate, and the moisture sensor can be moved to the highest point. Subsequently, the staff only needs to release the limit plate and pull the sensor probe downward to adjust the position of the sensor probe. After the sensor probe moves to the appropriate position, the staff only needs to release the sensor probe, and the second limit block can be made to abut against one of the first limit blocks, thereby keeping the sensor probe stable, thus reducing the operation difficulty of the staff. Subsequently, the staff only needs to connect the sensor probe with the soil, and the moisture of the soil can be measured by the moisture detector;
[0022] 3. In this application, after the sensor probe measures the soil, the staff needs to separate the sensor probe from the soil and reset the sensor probe. At this time, the staff only needs to slide the two moving blocks, and the two silica gel sheets can be made to abut against the sensor probe, thereby cleaning the sensor probe with the silica gel sheets, thus reducing the operation difficulty of the staff.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0030] As Figures 1-5 shown, an embodiment of the present application discloses a handheld soil moisture measuring device, including a housing 1, a moisture sensor 11, a sensor probe 2, a moisture meter 21, a fixing block 31, a limiting component 4, a stabilizing spring 5, a connecting rope 51, a connecting block 6, a moving block 8, a cleaning block 81, and a silicone sheet 9. The moisture sensor 11 is arranged inside the housing 1, and the sensor probe 2 is connected to the moisture sensor 11. The moisture meter 21 is connected to the moisture sensor 11. A fixing groove 3 is formed on the inner wall of the housing 1. The fixing block 31 is a block structure and is slidably arranged in the fixing groove 3, and the fixing block 31 is fixed to the moisture sensor 11.
[0031] A limiting groove 32 is formed on the inner wall of the housing 1. The limiting component 4 is arranged on the housing 1 and is used for limiting the moisture sensor 11. The limiting component 4 includes a limiting plate 41, a limiting spring 42, a first limiting block 43, and a second limiting block 44. The limiting plate 41 is a rectangular plate structure and is slidably arranged in the limiting groove 32. One end of the limiting spring 42 is fixed to the side wall of the limiting plate 41 away from the moisture sensor 11, and the other end of the limiting spring 42 is fixed to the inner wall of the limiting groove 32 away from the moisture sensor 11. The first limiting block 43 is a rectangular block structure. A plurality of first limiting blocks 43 are provided and are equally spaced on the side wall of the limiting plate 41. A first inclined surface 45 is formed on the edge where the side wall of the first limiting block 43 away from the limiting plate 41 intersects with its upper surface. The second limiting block 44 is a rectangular block structure and is fixed to the side wall of the moisture sensor 11. A second inclined surface 46 that matches the first inclined surface 45 is formed on the side wall of the second limiting block 44 close to the limiting plate 41. One end of the stabilizing spring 5 is fixed to the upper surface of the moisture sensor 11, and the other end of the stabilizing spring 5 is fixed to the inner top wall of the housing 1.
[0032] When the moisture sensor 11 is not subjected to an external force, the moisture sensor 11 continuously receives the upward acting force of the stable spring 5 and remains stable. When the staff needs to adjust the position of the sensor probe 2, the staff only needs to slide the limit plate 41, and the moisture sensor 11 can be moved to the highest point. Subsequently, the staff only needs to release the limit plate 41 and pull the sensor probe 2 downward to adjust the position of the sensor probe 2. When the sensor probe 2 moves to a suitable position, the staff only needs to release the sensor probe 2, and the second limit block 44 can be made to abut against one of the first limit blocks 43, thereby keeping the sensor probe 2 stable and reducing the operation difficulty of the staff. Subsequently, the staff only needs to connect the sensor probe 2 to the soil, and the moisture content of the soil can be measured by the moisture meter 21.
[0033] One end of the connecting rope 51 is fixed to the side wall of the limit plate 41 away from the first limit block 43, and the other end of the connecting rope 51 extends outside the housing 1 and is slidably connected. When the staff needs to slide the limit plate 41, the staff only needs to pull the connecting rope 51, and the limit plate 41 can follow the connecting rope 51 to move, thereby reducing the difficulty for the staff to move the limit plate 41.
[0034] In order to improve the user experience of the staff, the connecting rope 51 is made of a rubber band, and a connection is fixed to the end of the connecting rope 51. When the connecting rope 51 is not subjected to an external force, the connecting block 6 abuts against the side wall of the housing 1 under the action of the connecting rope 51, thereby keeping the connecting block 6 stable and reducing the probability of the connecting rope 51 being lost.
[0035] Moving grooves 7 are formed on both sides of the bottom surface of the housing 1. The moving block 8 is of a block structure and is slidably arranged in the moving groove 7. The cleaning block 81 is of a block structure and is fixed to the bottom surface of the moving block 8 for cleaning the sensor probe 2. The silica gel sheets 9 are of a sheet structure, and a plurality of silica gel sheets 9 are provided and are sequentially arranged on the side walls of the two cleaning blocks 81 close to each other.
[0036] After the sensor probe 2 measures the soil, the staff needs to separate the sensor probe 2 from the soil and reset the sensor probe 2. At this time, the staff only needs to slide the two moving blocks 8, and the two silica gel sheets 9 can be made to abut against the sensor probe 2, thereby cleaning the sensor probe 2 with the silica gel sheets 9 and reducing the operation difficulty of the staff.
[0037] In this embodiment, the working principle of a hand-held soil moisture measuring device is as follows: When the staff needs to measure the moisture of the soil, the staff needs to adjust the position of the sensor probe 2. At this time, the staff needs to turn off the limit component 4, so that the moisture sensor 11 can move to the highest point under the action of the stabilizing spring 5. Further, the staff needs to pull the sensor probe 2 downward to adjust the position of the sensor probe 2. When the staff stops moving the sensor probe 2, the sensor probe 2 remains stable under the combined action of the stabilizing spring 5 and the limit component 4, thereby reducing the operation difficulty of the staff and reducing the probability of soil entering the housing 1.
[0038] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications should also be regarded as the protection scope of the present invention.
