A sampling device for engineering testing

Abstract

This utility model relates to the field of engineering testing and sampling technology, and discloses a sampling device for engineering testing; it includes a positioning cylinder, and further includes a positioning ring fixed to the bottom of the surface of the positioning cylinder. Four support plates are fixedly connected to the surface of the positioning ring. A limit ring is provided on the surface of the positioning cylinder, and a positioning element is provided on the top of the limit ring. By opening a positioning groove on the top of the sampling cylinder, and cooperating with a descending pressure rod, after the sampling cylinder has finished sampling, the pressure rod can descend to press against the scraper ring inside the sampling cylinder, thereby scraping all the soil from the inner wall of the sampling cylinder out of the cylinder. This not only facilitates material discharge but also reduces the amount of soil remaining in the sampling cylinder during subsequent sampling. The guide plate and fixing plate allow the positioning cone to move, and the guide plate can be unfolded, thereby increasing the stability of the positioning cylinder during the sampling process. This eliminates the need for multiple operators and improves ease of use.
