[0042] The working principle of this utility model:

[0043] When in use, the user first adjusts the pull rod 51 downward to make the pull rod 51 move downward on the surface of the groove 4. In this way, through the downward movement of the pull rod 51, the pull groove 52 can be used to press the rotating shaft downward, so that the rotating shaft is squeezed, which can drive the rotating disk 7 to rotate. In this way, through the rotation of the rotating disk 7, the connecting rod 8 can be driven to rotate. In this way, through the rotation amplitude of the connecting rod 8, the travel groove 9 can be pressed backward to press the rotating shaft, so that the rotating shaft is squeezed by the travel groove 9, which can drive the positioning plate 62 to move rightward on the surface of the cross bar 10. The positioning plate 62 drives the positioning rod 61 to move backward, so that the positioning rod 61 moves out from the surface of the positioning groove 11, and then the transparent plate 23 is installed along the stroke of the installation groove 22, and the button 103 on the surface of the instrument body 101 can be pressed. Then, by using the pulling mechanism 5 and the positioning mechanism 6, the user can easily disassemble the transparent plate 23, so that when the user uses the humidity detector to detect wheat, the humidity detector can be dust-proof, and at the same time, it does not affect the detection of the humidity detector, thereby greatly improving the service life of the humidity detector.

[0044] In summary, the humidity detector for wheat purchase solves the problem that the existing humidity detector, when in use, generally requires the user to insert the detection needle into the interior of the wheat pile and then stop, so that the temperature inside the wheat pile is transmitted to the humidity detector through the detection needle, and when the humidity detector is used for a long time to detect the temperature inside the wheat pile, it is easy to cause more dust to enter the interior of the humidity detector, and the dust will cause the sensor inside the humidity detector to be damaged, so that its accuracy is reduced and the detected value is affected.
