Embodiment 1

[0017] Embodiment 1: as Figure 1-Figure 3 As shown, a rotary soil crust collection device used in 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, and 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, and the opening of the sample bag 2 is sleeved on the knife holder 4 through a rubber band.

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

[0019] Preferably, the fork-shaped ends of the above-mentioned knife rest 4 are provided with guide plates 6, one section of the guide plate 6 is inserted into the sample bag 2, and the other section is located at the lower side of the blade 5, and the guide plate is provided to facilitat...

Embodiment 2

[0024] Embodiment 2: A method for using a rotary soil crust collection device in karst areas, the method is: adjust the limit nut and the roller to the set height, bind the sample bag on the knife holder, and operate the rotary handle to make the scraper Rotate around the positioning rod, and the scraper samples the soil crust. After walking around, remove the sample bag, reinstall a new sample bag, and change the position of the positioning rod to sample the soil crust until the sampling is completed. Finally, clean the edge of the blade.

Abstract

The invention discloses a rotary soil crust collection device used in a karst region. The rotary soil crust collection device comprises a scraper, a sample bag and a positioning rod. One end of the scraper is rotatably connected with the positioning rod; the scraper comprises a scraper holder and a blade; the scraper holder is fork-shaped; the both ends of the blade are connected with the scraperholder; and an opening of the sample bag is connected to the scraper holder in a sleeving manner. By rotating the scraper, the rapid collection of soil crust can be realized; the crust thickness is uniform; and the test is more accurate. The crust sample can be collected into the sample bag by only pressing the blade on the ground to move forwards. The operation is greatly simplified and the collection efficiency is improved. The rotary soil crust collection device has the advantages such as the simple structure, convenient operation and low cost.

Description

technical field [0001] The invention belongs to the technical field of soil crust collection equipment for testing, and relates to a rotary soil crust collection device used in karst areas and a use method thereof. Background technique [0002] Existing soil crust research in karst areas is usually collected manually with a razor blade, and the thickness of the collected crust is uneven, resulting in inaccurate data during the test. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotary soil crust collection device for karst areas and its use method, so as to solve the technical problems existing in the prior art. [0004] The technical solution adopted by the present invention is: a rotary soil crust collection device used in karst areas, including a scraper, a sample bag and a positioning rod, one end of the scraper is rotatably connected to the positioning rod, the scraper includes a knife holder and a blade...
