[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] Reference Figures 1 to 4This application provides a soil testing device, including a tester 1. A penetration component 2 is provided on the side of the tester 1, and a testing component 3 is provided on the inner side of the penetration component 2. The penetration component 2 includes a main body cylinder 21, a conical cylinder 22 is fixedly installed at the bottom of the main body cylinder 21, a spiral blade 23 is fixedly installed on the outer side of the conical cylinder 22, and handles 24 are fixedly installed on both sides of the top of the main body cylinder 21. The testing component 3 includes a sensor 33, which is slidably connected inside the main body cylinder 21.
[0031] The conical cylinder 22 is internally connected to the main body cylinder 21. The bottom of the spiral blade 23 begins at the connection point between the main body cylinder 21 and the conical cylinder 22. A probe 34 is fixedly mounted on the bottom of the sensor 33. The probe 34 is located inside the connection point between the main body cylinder 21 and the conical cylinder 22. A connecting hole 25 is provided at the bottom of the conical cylinder 22, and the bottom of the probe 34 is located inside the connecting hole 25. A placement box 5 is fixedly mounted on the front of the main body cylinder 21, above the spiral blade 23, and the detector 1 is inserted into the placement box 5.
[0032] In this embodiment, before detection, the detector 1 is first inserted into the placement box 5. Then, the conical cylinder 22 is inserted into the soil. After insertion, the main body cylinder 21 is rotated by the handle 24, and the main body cylinder 21 and the conical cylinder 22 are sent into the soil through the outer spiral plate 23. This allows the sensor 33 and the probe 34 to be sent into the depth to be detected. During the insertion, the outer main body cylinder 21 and the conical cylinder 22 protect the probe 34 while ensuring that it is sent into the specified depth. This also enables the detection of deeper soil.
[0033] Reference Figures 1 to 4 In one aspect of this embodiment, a screw 32 is rotatably connected to the top of the sensor 33. The screw 32 is screwed through the top wall of the main body cylinder 21, and a knob 31 is fixedly installed on the top of the screw 32 and above the main body cylinder 21.
[0034] A limiting rod 36 is fixedly installed on the inner wall of the main body cylinder 21. The limiting rod 36 passes through the interior of the sensor 33 from top to bottom. The sensor 33 is slidably connected to the limiting rod 36. The outer wall of the limiting rod 36 and the connection point of the sensor 33 are in contact with each other.
[0035] A data cable 4 is fixedly installed between the sensor 33 and the detector 1. The data cable 4 moves through the top wall of the main body cylinder 21. A limit block 35 is fixedly installed on the inner wall of the main body cylinder 21. The data cable 4 moves through the inside of the limit block 35.
[0036] In this embodiment, after the probe 34 is inserted into the designated position, the screw 32 is rotated by turning the upper knob 31. The screw 32 can move downwards as it rotates, causing the sensor 33 and probe 34 to move downwards. The limiting rod 36 ensures that the sensor 33 does not rotate while moving downwards. As the sensor 33 moves downwards, the probe 34 passes through the connecting hole 25 and inserts into the soil below. The sensor 33 and probe 34 work together to achieve the detection function. This method of probe insertion significantly reduces the insertion stroke of the probe 34 when detecting deeper soil, thereby further improving the safety of the probe 34. When the sensor 33 moves downwards, the data cable 4 moves downwards synchronously with it. The limiting block 35 sleeved on the outside of the data cable 4 ensures that the data cable 4 does not move horizontally without affecting its vertical movement, preventing it from interfering with the screw 32. The sensor 33 can be a moisture, temperature, salinity, or pH sensor, etc., allowing for the detection of different soil parameters through different types of sensors.
[0037] Working principle: Before detection, the detector 1 is first inserted into the placement box 5. Then, the conical cylinder 22 is inserted into the soil. After insertion, the main body cylinder 21 is rotated by the handle 24, and the outer spiral plate 23 pushes the main body cylinder 21 and the conical cylinder 22 into the soil. This allows the sensor 33 and probe 34 to be inserted to the required detection depth. During insertion, the outer main body cylinder 21 and conical cylinder 22 protect the probe 34 while ensuring its safety at the designated depth, and also enabling detection of deeper soil. After the probe 34 is inserted to the designated position, the screw 32 is rotated by rotating the upper knob 31. As the screw 32 rotates, it can... Moving downwards, the screw 32 moves downwards, causing the sensor 33 and probe 34 to move downwards. The limiting rod 36 ensures that the sensor 33 will not rotate while moving downwards. As the sensor 33 moves downwards, the probe 34 passes through the connecting hole 25 and is inserted into the soil below. The sensor 33 and probe 34 work together to achieve the detection function. This method of probe 34 insertion can greatly reduce the insertion stroke of the probe 34 when detecting deeper soil, thereby further improving the safety of the probe 34. The sensor 33 can be a moisture, temperature, salinity, and pH sensor, etc. Different types of sensors can be used to detect different soil parameters.
