Description

Technical Field

[0001] The utility model belongs to the technical field of soil detectors, and particularly relates to a soil detector with a fixing structure. Background Art

[0002] A soil detector is a powerful and widely used device. In the agricultural field, farmers can understand the content of nutrient elements in the soil through the soil detector, so as to apply fertilizers reasonably, improve the yield and quality of crops. At the same time, it can also detect the pH value and organic matter content of the soil, providing a scientific basis for soil improvement and sustainable agricultural development. In the environmental field, the soil detector can help researchers monitor the content of heavy metals, organic substances and other pollutants in the soil, evaluate the degree of soil pollution, and provide a basis for formulating environmental protection measures. In ecological research, by detecting and comparing the soil components of different ecosystems, ecologists can understand the laws of material cycle and energy flow between different ecosystems, providing a theoretical basis for ecological protection and restoration.

[0003] However, there are some problems in the existing technology: when the existing soil detector is in use, generally, the probe is inserted into the soil by the staff, and the sensor connected to the probe transmits the data to the host to measure the data. However, due to the poor environment in the soil, the probe often wears, rusts, bends and breaks, thus affecting the detection accuracy. Therefore, the staff needs to replace the probe. However, the probe and the sensor of the existing detector are often integrally designed, so that the staff cannot replace the probe alone, which increases the use cost. Therefore, we propose a soil detector with a fixing structure. Summary of the Utility Model

[0004] Aiming at the problems existing in the existing technology, the purpose of the utility model is to provide a soil detector with a fixing structure, which can replace the probe alone by setting a clamping block, thereby reducing the use cost.

[0005] The utility model is realized as follows: a soil detector with a fixing structure includes a host, a sensor and a signal line. The host and the sensor are electrically connected through the signal line. A probe is arranged on the sensor. A circular groove is opened on the sensor. The probe is movably inserted into the circular groove. A clamping groove is opened on the surface of the probe. A square groove is opened on the surface of the sensor. A clamping block is slidably inserted into the square groove, and one end of the clamping block close to the probe is clamped into the clamping groove. A rocker mechanism is also arranged on the sensor, and the clamping block can slide in the square groove through the rocker mechanism.

[0006] Optionally, the rocker mechanism includes a fixing block, the fixing block is fixedly installed on the sensor, and a rotating plate is rotatably connected to the fixing block.

[0007] Optionally, a square plate is fixedly installed on the clamping block, and a round rod is fixedly installed on the square plate.

[0008] Optionally, a through hole is formed in the rotating plate, and the inner wall of the through hole is slidably connected to the outer surface of the round rod.

[0009] Optionally, a spring is fixedly connected to the sensor, and the other end of the spring is fixedly connected to the rotating plate.

[0010] Optionally, convex blocks are fixedly installed on both sides of the sensor, and rubber pads are fixedly installed on the convex blocks.

[0011] Optionally, the number of the clamping blocks is two, and the opposite surfaces of the two clamping blocks are inclined.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the plug-in design between the sensor and the probe, the probe can be individually disassembled and replaced, thereby reducing the use cost. And due to the design of the rocker mechanism, during normal use, the clamping block can be stably held inside the square groove, and one end of the clamping block can be stably clamped in the card slot to fix the probe. When replacing the probe, only need to move the clamping block through the rocker mechanism to release the fixing effect on the probe, which facilitates the staff to replace the probe.

Detailed implementation mode

[0021] To further understand the utility model content, characteristics and efficacy of the present utility model, the following embodiments are hereby cited and described in detail in conjunction with the attached drawings as follows.

[0022] As Figures 1 to 5 shown, a soil detector with a fixed structure provided by an embodiment of the present utility model includes a main unit 1, a sensor 2 and a signal line 3. The main unit 1 and the sensor 2 are electrically connected through the signal line 3. A probe 4 is provided on the sensor 2. A circular groove 5 is opened on the sensor 2. The probe 4 is movably inserted into the circular groove 5. A card slot 6 is opened on the surface of the probe 4. A square groove 7 is opened on the surface of the sensor 2. A card block 8 is slidably inserted into the square groove 7. One end of the card block 8 close to the probe 4 is clamped into the card slot 6. A seesaw mechanism is further provided on the sensor 2. The card block 8 can slide in the square groove 7 through the seesaw mechanism.

[0023] Furthermore, the seesaw mechanism includes a fixed block 9. The fixed block 9 is fixedly installed on the sensor 2. A rotating plate 10 is rotatably connected to the fixed block 9.

[0024] Furthermore, a square plate 11 is fixedly installed on the card block 8. A round rod 12 is fixedly installed on the square plate 11.

[0025] Furthermore, a through hole 13 is opened on the rotating plate 10. The inner wall of the through hole 13 is slidably connected to the outer surface of the round rod 12. By pressing the end of the rotating plate 10 farther away from the sensor 2 to rotate closer to the sensor 2, the other end of the rotating plate 10 can be made to rotate away from the sensor 2. Thus, the inner wall of the through hole 13 can be made to squeeze the outer surface of the round rod 12, so that the round rod 12 drives the card block 8 to move away from the probe 4 through the square plate 11. Furthermore, the end of the card block 8 close to the probe 4 can be made to move out of the card slot 6, thereby releasing the fixing effect on the probe 4 and facilitating the staff to replace the probe 4.

[0026] Furthermore, a spring 14 is fixedly connected to the sensor 2. The other end of the spring 14 is fixedly connected to the rotating plate 10. By setting the spring 14 in a compressed state, due to the elastic force of the spring 14, a thrust will be generated on the rotating plate 10, so that the rotating plate 10 can maintain a pressing state on the card block 8, and further the card block 8 can maintain a clamping and fixing effect on the probe 4.

[0027] Furthermore, convex blocks 15 are fixedly installed on both sides of the sensor 2. Rubber pads 16 are fixedly installed on the convex blocks 15. Through the design of the convex blocks 15, it is convenient for the staff to lift the sensor 2 to pull out the probe 4 inserted in the soil. At the same time, since the rubber pads 16 have a soft property, it can make the staff more comfortable when applying force by holding the convex blocks 15 through the rubber pads 16.

[0028] Further, the number of the clamping blocks 8 is two, and the opposite faces of the two clamping blocks 8 are inclined. Through the design that the opposite faces of the two clamping blocks 8 are inclined, when the staff installs the probe 4, the staff can directly push the probe 4 so that the probe 4 presses the inclined surface of the clamping block 8, causing the two clamping blocks 8 to move away from each other. Subsequently, the clamping block 8 is clamped in the clamping groove 6 to fix the probe 4, which facilitates the staff to install and use.

[0029] Working principle: During normal detection work, the staff inserts the probe 4 into the soil, and the sensor 2 transmits the detected data to the host 1. When the probe 4 is damaged and needs to be replaced, the staff can press the rotating plate 10 to make the rotating plate 10 rotate and compress the spring 14, so that the inner wall of the through hole 13 presses the outer surface of the round rod 12, and then can drive the two clamping blocks 8 to move away from each other. When the part of the clamping block 8 located inside the clamping groove 6 is withdrawn from the clamping groove 6, the limiting effect on the probe 4 is released, and the staff can remove the probe 4 for replacement.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
