Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling equipment, specifically a soil sampling device for hydrogeological and environmental geological exploration. Background Technology

[0002] As is well known, soil sampling is required in hydrogeological and environmental geological exploration. A search revealed a Chinese patent (publication number: CN217819429U) for a soil sampling device for hydrogeological and environmental geological exploration. The device includes an insert, a foot pedal sleeve that slides on the outside of the insert, multiple foot pedals that are fixedly connected to the outside of the foot pedal sleeve, and a fastening handwheel that is threaded onto the outside of the foot pedal sleeve. During use, rotating the fastening handwheel on the foot pedal sleeve creates tension between the insert and the handwheel, which acts as a set screw to fix the foot pedal sleeve to the insert. However, because the insert needs to be repeatedly stepped on by the user during insertion into the ground, the handwheel and insert are prone to loosening due to repeated foot vibration, causing the foot pedal sleeve and insert to slide. Therefore, it is necessary to repeatedly rotate the fastening handwheel to increase the tension between the fastening handwheel and the insert, further enhancing the friction of the contact surfaces.

[0003] Because the pedal sleeve slides between itself and the insertion cylinder, the user's foot steps on the pedal, causing the user to fall quickly, which is not conducive to the user's safety. In addition, the repeated turning of the fastening handwheel increases the sampling time and reduces work efficiency. Utility Model Content
