Description

Technical Field

[0001] The utility model relates to the technical field of soil layer thickness measurement, and more specifically to a soil layer thickness measurement device for land planning. Background Art

[0002] Land planning refers to the long-term arrangement of the rational use of land within a country or a certain region according to the prospects and needs of economic development. One of the steps in land planning is to evaluate the quality of the land and confirm the land attributes based on the results of the quality evaluation. When conducting land quality evaluation, it is first necessary to measure the thickness of the land and obtain land samples for inspection and analysis.

[0003] After retrieval, the existing patent (publication number: CN219624656U) discloses a soil layer thickness measurement device for land planning. During its use, the overall device is supported on the ground by support feet, and then the driving gear is rotated by turning the hand crank. The rotation of the driving gear drives the driven gear to rotate, and the rotation of the driven gear drives the lifting rod engaged with it to move downward. Since the diameter of the driven gear is larger than that of the driving gear, based on the lever principle, only by quickly turning the hand crank can a small force be used to drive the lifting rod to move downward to break the soil, so as to measure the soil layer thickness. However, the inventor found the following problems in the process of implementing the present utility model: when the above-mentioned soil layer thickness measurement device is in use, it is necessary to turn the hand crank, and when turning the hand crank, a lateral force will be applied to the overall device, and the overall device is simply placed on the ground by support feet, and the stability of the overall device is poor. Therefore, when turning the hand crank, the overall device is prone to shaking and skewing, resulting in the interruption of the sampling action, delaying the efficiency of soil layer sampling and detection. Moreover, during detection, in order to improve the accuracy of detection, it is often necessary to take samples multiple times at a rated interval. For the above-mentioned device, when taking samples multiple times, it is also necessary to measure the distance additionally, which has the defect of cumbersome operation and further reduces the detection efficiency.

[0004] In view of this, the present utility model provides a soil layer thickness measurement device for land planning to solve this problem. Summary of the Utility Model
