Shallow soil sampling components

Abstract

The invention relates to a shallow soil sampling component. The shallow soil sampling component comprises a soil sampling sleeve and a soil sampling device, wherein soil sampling grooves are formed in the side wall of the soil sampling sleeve, penetrate through the side wall of the soil sampling sleeve and are axial to the axis of the soil sampling sleeve, and the soil sampling grooves are symmetrical about the radial direction of the soil sampling sleeve; the soil sampling device comprises a U-shaped frame, the U-shaped frame comprises a fixed insertion plate and a fixed supporting plate, a movable insertion plate parallel to the fixed insertion plate is installed between the fixed insertion plate and the fixed supporting plate, and the movable insertion plate is movably installed on a guide rod between the fixed insertion plate and the fixed supporting plate; a clamping screw is installed on the fixed supporting plate in a spiral mode, and a clamping groove matched with the clamping screw is formed in the side wall of the soil sampling sleeve; the fixed insertion plate and the movable insertion plate are inserted in two opposite soil sampling grooves, and the end of the clamping screw abuts against the movable insertion plate; through holes penetrating through the two sides of the fixed insertion plate are evenly distributed in the fixed insertion plate, and an extrusion device is installed on the outer side of the fixed insertion plate.

Description

technical field

[0001] The invention relates to the field of geological exploration, in particular to an earth-borrowing tool for shallow soil. Background technique

[0002] In geological exploration, soil fetchers are usually used to take underground soil samples. For shallow soil sampling, the existing soil-taking tools all have a cylindrical structure. When taking soil, the cylinder is inserted into the ground, and the inner chamber of the cylinder contains samples after being pulled out. The main way to take out the samples in the cylinder is at present by shaking the soil fetcher. When shaking, the samples are easy to spill and the operation is troublesome.

[0003] In response to the above-mentioned problems, the applicant applied for a patent titled "soil-taking component for geological exploration" on the same day. In the technical solution provided, the soil sample in the soil-borrowing sleeve was taken out by using the inserting plate, which was compared with the ...
