[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1: Figure 1-Figure 3 As shown, a rotary soil crust collection device for karst areas includes a scraper 1, a sample bag 2 and a positioning rod 3. One end of the scraper 1 is rotatably connected to the positioning rod 3. The scraper 1 includes a knife holder 4 and a blade 5. The knife holder 4 is a fork-shaped structure. Both ends of the blade 5 are connected to the knife holder 4. The opening of the sample bag 2 is connected to the knife holder 4 by a rubber band.

[0018] Preferably, the lower end of the positioning rod 3 is a spike portion, and the positioning rod 3 is provided with a limiting nut 13, which can realize the thickness control of the scraper.

[0019] Preferably, guide plates 6 are provided at both ends of the fork shape of the above-mentioned blade holder 4. One end of the guide plate 6 is inserted into the sample bag 2, and the other end is located at the lower side of the blade 5. The guide plates are provided to facilitate the delivery of the crust into the sample bag, playing a role in transition and transfer.

[0020] Preferably, a rotary handle 14 is provided at the other end of the scraper 1. By operating the rotary handle, the operation is easier and more time-saving and labor-saving.
