Outward turning piece type soil sampling device

Abstract

The invention relates to an outward turning piece type soil sampling device. The outward turning piece type soil sampling device comprises a soil sampling sleeve installed in the center of a soil sampling frame, the upper end of the soil sampling sleeve is provided with a soil sampling handle, and the soil sampling sleeve is of a multi-segment structure and comprises an upper pressing segment, a connecting segment, a middle turning piece segment and a lower pressing segment; the upper pressing segment is fixedly connected with the soil sampling handle, the connecting segment and the upper pressing segment are spirally connected, the lower end of the connecting segment is provided with a fixing ring, the middle turning piece segment comprises multiple turning pieces, the upper ends of the turning pieces are arranged on the fixing ring in a sleeving mode, and after the turning pieces form a barrel in an enclosing mode, the lower ends of the turning pieces are spirally connected with the lower pressing segment; the soil sampling handle comprises a cross-shaped main frame and a ring seat arranged in the center of the cross-shaped main frame, a hand lever with an outer thread is movably installed in the ring seat, and the upper end of the hand lever is provided with a handle; the soil sampling frame comprises multiple soil sampling stand bars which are distributed in a central symmetry mode and supporting transverse bars which are installed at the top ends of the soil sampling stand bars and extend to the center of the soil sampling frame, the inner ends of the support transverse bars are jointly and fixedly connected with a spiral sleeve, and the spiral sleeve is matched with the hand lever to form a lead screw assembly.

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. When the barrel is long, it is inconvenient to take out the soil sample in the inner cavity quickly, and it needs to be shaken by hand or squeezed from the end, which is time-consuming and laborious. The name that the applicant applied for on the same day is "Eternal Slice Type Soil Extractor", which solves the above problems, but what needs to be improved is that the technical solution in the above patent is a manual push-down soil fetch, and there is a problem in the push-down process...

Problems solved by technology

When the cylinder is long, the soil sample in the inner cavity is not convenient to take out quickly, and it needs to be shaken by hand or squeezed from the end, which is time-consuming and laborious

The name that the applicant applied for on the same day is "Eternal Slice Type Soil Extractor", which solves the above problems, but what needs to be improved is that the technical solution in the above patent is a manual push-down soil fetch, and there is a problem in the push-down process. A certain degree of difficulty, the efficiency of soil extraction needs to be improved
