Embodiment 1

[0014] Embodiment 1: as Figure 1-Figure 2 As shown, a soil crust collection device for testing in karst areas includes a scraper 1 and a sample bag 2. The scraper 1 includes a knife handle 3, a knife holder 4 and a blade 5. The knife holder 4 is fixedly connected to one end of the knife handle 3, and the knife The frame 4 is a fork-shaped structure, the two ends of the blade 5 are connected to the knife frame 4, and the opening of the sample bag 2 is sleeved on the knife frame 4 through a rubber band. , can realize the rapid collection of soil crusts, the thickness of the crusts is uniform, and avoid damaging the integrity of the crusts, the test is more accurate, just press the blade to move forward on the ground, and the crust samples can be collected into the sample bag, The operation is greatly simplified and the collection efficiency is improved.

[0015] Preferably, the fork-shaped ends of the above-mentioned knife rest 4 are provided with guide plates 6, one section o...

Embodiment 2

[0019] Embodiment 2: A method for using a soil crust collection device for testing in karst areas, the method is: adjust the rollers to a set height, bind the sample bag on the knife holder, operate the handle to sample the soil crust, walk the device After a fixed distance, remove the sample bag, reinstall a new sample bag for soil crust sampling, until the sampling is completed, and clean the edge of the blade after each sampling.
