[0014] When the utility model is in use, the sliders on both sides of the sensor body are aligned with the slide grooves in the protective shell, and then pushed toward one side of the protective shell. When pushed, the detection needle can be driven to move out of the perforation until the limit rod on the surface of the sensor body is pushed to be aligned with the limit groove, and then the limit rod is toggled, and the limit rod will drive the rotating drum to rotate on the surface of the fixed rod until one end of the limit rod is rotated to the inside of the limit groove, so that the limit rod cannot be moved, thereby the sensor body is stuck in the protective shell. After the detection is completed, the sensor body is pulled outward by the push-pull handle, and the sensor body will drive the detection needle to move into the protective shell. During the movement, the brush on the inner side of the perforation can clean the surface of the detection needle to avoid affecting the service life of the detection needle. Until the sensor body and the detection needle are completely pulled into the protective shell, one side of the sensor body will contact the movable frame, and the push-pull handle is outside one side of the movable frame. The sensor body and the protective shell can be lifted as a whole by holding the push-pull handle to perform detection at other positions. It is convenient and quick to solve the problem that it is inconvenient to use the detection needle when the detection needle is protected and the service life is affected by not cleaning the detection needle.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides a technical solution: a soil temperature and humidity sensor with a protective structure, including a protective shell 1 and a sensor body 4, one side of the protective shell 1 is hingedly connected with a movable frame 2, the other side of the protective shell 1 is provided with a through hole 11, the opposite surface of the inner side of the protective shell 1 is provided with a slide groove 15, the opposite surface of the inner side of the protective shell 1 is fixedly connected with a limiting groove 16, the surface of the sensor body 4 is fixedly connected with two fixed blocks 7, the surface of the fixed block 7 is fixedly connected with a fixed rod 8, the surface of the fixed rod 8 is rotatably connected with a rotating drum 17, the surface of the rotating drum 17 is fixedly connected with a limiting rod 10, one side of the sensor body 4 is fixedly connected with a wiring terminal 5, and both sides of the sensor body 4 A slider 14 is fixedly connected, and the size of the slider 14 and the slide groove 15 are adapted, and the size of the limit rod 10 and the limit groove 16 are adapted. When the sensor body 4 needs to be used, the movable frame 2 is opened, and then the sliders 14 on both sides of the sensor body 4 are aligned with the slide groove 15 in the protective shell 1, and then pushed to one side of the protective shell 1 until the limit rod 10 on the surface of the sensor body 4 is pushed to align with the limit groove 16, and then the limit rod 10 is moved, and the limit rod 10 will drive the rotating drum 17 to rotate on the surface of the fixed rod 8 until one end of the limit rod 10 is rotated to the inside of the limit groove 16, so that the limit rod 10 is immovable, thereby the sensor body 4 is stuck in the protective shell 1.

[0024] like Figure 1 and Figure 2 As shown, a handle 3 is fixedly connected to the surface of the movable frame 2 , and a push-pull handle 6 is fixedly connected to the surface of the sensor body 4 . The handle 3 is used to open and close the movable frame 2 , and the push-pull handle 6 is used to push and pull the sensor body 4 .

[0025] like Figure 3 and Figure 4As shown, brushes 12 are evenly arranged on the inner side of the perforation 11, and a plurality of detection needles 13 are fixedly connected to the other end of the sensor body 4. The surface of the detection needle 13 contacts one end of the brush 12. When the sensor body 4 is pushed or pulled, the detection needle 13 can be driven to move from the perforation 11, and the brush 12 can clean the surface of the detection needle 13 when moving.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, one end of the fixing rod 8 is fixedly connected with an anti-dropping block 9, and one side of the sensor body 4 is fixedly connected with a wiring terminal 5. The anti-dropping block 9 can prevent the rotating drum 17 from falling from the surface of the fixing rod 8, and the wiring terminal 5 is used to connect electrical components.

[0027] Working principle: When in use, open the movable frame 2, then align the sliders 14 on both sides of the sensor body 4 with the slide grooves 15 in the protective shell 1, and then push the protective shell 1 to one side. When pushing, the detection needle 13 can be driven to move out of the perforation 11 until the limit rod 10 on the surface of the sensor body 4 is pushed to align with the limit groove 16, and then the limit rod 10 is moved. The limit rod 10 will drive the rotating drum 17 to rotate on the surface of the fixed rod 8 until one end of the limit rod 10 is rotated to the inside of the limit groove 16, so that the limit rod 10 cannot be moved, thereby clamping the sensor body 4 inside the protective shell 1;

[0028] Then, the detection needle 13 is aligned with the soil and inserted. Since the sensor body 4 is stuck inside the protective shell 1, when the detection needle 13 is inserted into the soil, the sensor body 4 will not move due to the force problem;

[0029] After the detection is completed, the sensor body 4 is pulled outward by the push-pull handle 6, and the sensor body 4 will drive the detection needle 13 to move into the protective shell 1. During the movement, the brush 12 on the inside of the perforation 11 can clean the surface of the detection needle 13 to avoid affecting the service life of the detection needle 13. Until the sensor body 4 and the detection needle 13 are completely pulled into the protective shell 1, one side of the sensor body 4 will contact the movable frame 2, and the push-pull handle 6 is outside one side of the movable frame 2. The sensor body 4 and the protective shell 1 can be lifted as a whole by holding the push-pull handle 6 to perform detection at other positions, which is convenient and quick.

[0030] Through the above operation, the detection needle 13 can be protected and used conveniently, and the detection needle 13 can be cleaned.
