Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] A kind of sandy soil sampler of the present invention, as figure 1 As shown, including the iron pipe 1, there are 2-4 handles 2 evenly distributed around the top of the iron pipe 1, and the bottom end of the iron pipe 1 is fixed with a drill bit 3; the interior of the iron pipe 1 is divided into a buffer chamber and a sampling chamber from top to bottom; Several sampling units are sequentially arranged in the sampling chamber from top to bottom.

[0020] Such as figure 2 As shown, the sampling unit includes an annular boss 4 located on the inner wall of the iron pipe 1 , a baffle 5 is arranged on the boss 4 , and several feeding grooves 6 are arranged along the inner wall of the iron pipe 1 .

[0021] The quantity of feed tank 6 is 3-5.

[0022] The widths of the corresponding bosses 4 in the sampling unit increase sequentially fro...

Abstract

The invention discloses a desertified soil sampler. The desertified soil sampler comprises an iron pipe, 2-4 handles are evenly distributed on the periphery of the top end of the iron pipe, and a drill bit is fixedly connected to the bottom end of the iron pipe; the interior of the iron pipe is divided into a buffer cavity and a sampling cavity from top to bottom; and a plurality of sampling unitsare sequentially arranged in the sampling cavity from top to bottom. The desertified soil sampler is chiseled in through the drill bit, so that better sampling of the sampling unit is facilitated; byarranging the iron pipe and connecting the iron pipe with the drill bit, the phenomenon of inaccurate sampling caused by random flowing of soil samples during pit digging and sampling is avoided, thesamples can be accurately collected according to the depth of the soil samples through the layer-by-layer progressive boss width, the soil samples of all soil layers are prevented from being pollutedby one another through the falling baffle, the structure is simple, and the practical value is very good.

Description

technical field [0001] The invention belongs to the technical field of sampling equipment, and in particular relates to a sandy soil sampler. Background technique [0002] On the basis of understanding pollution sources, pollution methods, pollution history and current situation, arrange sampling points in full consideration of soil type, soil parent material, topography, natural vegetation or crops, etc. If the field is not large and the shape is regular, the diagonal method and the quincunx method can be used; if the shape of the field is irregular, the terrain changes, or the area is large, the chessboard method or the serpentine method can be used. Strive for the conditions of the sampling points to be representative of the main soil types and their degree of contamination. [0003] The distribution of pollutants in the soil has not only horizontal differences caused by the distance from the pollution source, but also vertical differences caused by time and other factor...
