Abstract

The invention discloses an undisturbed soil sampling tool with a sealed storage function. The undisturbed soil sampling tool comprises a sampling tool and a sealing storage box, wherein the sealed storage box is arranged in the sampling tool in a manner of inserting from bottom to top and is limited on the upper side; a pair of bendable metal plates, which are arranged in parallel, are arranged in the sealing storage box in a sliding manner; chamfers are molded on lower end faces of the pair of metal plates, and the lower end faces can be used for closing the lower end of the sealing storage box; the sealing storage box is internally provided with a supporting plate capable of sliding up and down; a plurality of guide driving devices, which are uniformly distributed, are arranged on the supporting plate; the guide driving devices drive one pair of the metal plates to slide through the sampling tool. According to the undisturbed soil sampling tool disclosed by the invention, a soil sample can be stored in the sealing storage box in a sealed manner, and an original state of the undisturbed soil sample is kept to the greatest extent, so that interferences are avoided.

Description

technical field [0001] The invention relates to a soil sample extraction technology, in particular to an undisturbed soil sampling tool with the function of sealing and storing. Background technique [0002] In the traditional ring-knife soil sampling, first select the location for excavating the soil profile in the field, then excavate the soil profile, and sample in layers according to the profile level. Put the ring cutter holder on the ring cutter of known weight, press the edge of the ring cutter vertically downward into the soil until the ring cutter barrel is full of samples, then use the soil cutter to cut the soil around the ring cutter, and take out the filled sample. For the ring knife of soil, cut off the excess soil at both ends of the ring knife, and wipe off the soil outside the ring knife. Immediately cover both ends of the ring knife to prevent water from evaporating, then weigh and record. The process of capping the two ends of the ring knife is not easy, ...
