Description

Technical Field

[0001] The utility model relates to the technical field of soil and water conservation monitoring, in particular to a safety drill bit device for soil and water conservation monitoring. Background Art

[0002] Inserting a drill rod is a method of soil and water monitoring. It involves regularly inserting a number of drill rods into the ground, marking the position on the drill rods that is level with the soil surface, and using that position as the original height point. After rainfall occurs, the thickness of the soil surface that has dropped is observed, thereby observing the amount of soil erosion.

[0003] For example, patent number CN220271327U is a safety drill bit device for soil and water conservation monitoring, comprising: a drill bit rod, the upper end of which is provided with an external thread; a locking ring threadedly connected to the external thread; and a support ring arranged below the locking ring and threadedly connected to the external thread, the peripheral side of the support ring is fixedly connected with a plurality of connecting ears, and the plurality of connecting ears are hingedly connected with a plurality of support plates in a one-to-one correspondence, and the end of the support plate close to the connecting ear is provided with a plurality of stop surfaces. The above document still has shortcomings. When in use, the locking ring and the support ring are moved away from each other by rotating any one or two of the rotating locking ring and the support ring, so that the stop surface of the support plate is matched with the clearance of the locking ring, and the support plate is flipped so that Multiple support plates are in the expanded or folded state at the same time. By rotating any one or two of the rotating locking ring and the support ring, the locking ring and the support ring are brought close to each other, so that the stop surface of the support plate at one end close to the connecting ear abuts against the support ring. At this time, the expanded or folded state of the support plate can be locked. However, the position of the support plate in the above document can be rotated at will. When supporting the drill rod, the position of the drill rod may be tilted, which is not convenient for supporting the drill rod. At the same time, the drill tip of the drill rod will have certain wear and tear after long-term use. The drill tip is prone to rust or blunting, which is not conducive to later use and it is not convenient to replace the rusted or blunt drill tip. Utility Model Content
