[0002] In the process of crop cultivation, it is often necessary to measure the plant height of crops. Plant height is an important growth indicator of crops and is closely related to crop biomass and yield. By monitoring the changes in crop height to determine the health and growth status of crops, it can provide an important reference basis for crop production management and regulation. Reasonable plant height is the basis for achieving stable and high yields of crops.

[0003] A crop height measuring device is disclosed in Chinese utility model CN217442534U. When measuring crops, the crop height measuring device moves the second telescopic rod so that the baffle is located at the top of the crop. Then, the distance between the distance measuring surface and the distance measuring sensor can be measured by the distance measuring sensor. The actual height of the crop can be obtained by analysis and calculation, and displayed on the display terminal for easy observation. Compared with the measuring device provided by the prior art, the crop height measuring device provided by the utility model has a distance measuring sensor located in a sealed environment formed by the first cavity and the second cavity, which ensures that the measurement result is not disturbed by the external environment and realizes accurate measurement of the crop height. However, the crop height measuring device still has the following problems during use:

[0004] The crop height measuring device realizes detection by pressing the second telescopic rod to push the baffle to the top of the crop. However, there is no pushing component on the top, so it is necessary to directly push the top of the second telescopic rod. As a result, when measuring lower plants, it is often necessary to maintain a lower posture to push the second telescopic rod, which makes measurement very inconvenient. Utility Model Content
