Problems solved by technology

If soil drills are used for collection, the layering depth can generally be controlled at about 10cm, and finer layered samples cannot be accurately obtained, and the number of samples collected by each drill is small, making it difficult to complete simultaneous testing of multiple items. In addition, due to multiple reciprocations In the same borehole, affected by the collapse of the hole wall, samples from different layers are often mixed, which affects the representativeness of the samples; if destructive excavation is used, it can only excavate at the soil collection point slightly deeper than the maximum sampling depth. Soil pit, and then collect samples on the soil profile of the pit wall. This method is time-consuming and laborious. Although the layering depth can be accurately controlled within 2-4cm, due to the characteristics of manual operation, the samples of each layer Sampling area and sampling volume are often difficult to control precisely
[0004] Both Chinese patent 200910067207.X and Chinese patent 200520022170.6 provide an improved soil sampler, but still have the above-mentioned technical defects, which cannot meet people's needs well

Embodiment Construction

[0038] See attached Figure 1-6 , the structure of the first embodiment of the present invention includes a rectangular sampling frame and a rectangular scraper 2 that can slide and scrape soil along the sampling frame; the sampling frame includes a rectangular horizontal frame 11 and four rectangles along the horizontal frame 11 inside Due to the existence of the vertical wall 12, the horizontal frame 11 can be firmly fixed on the ground with the help of tools such as rubber hammers, so as to determine the sampling range and the sliding guide rail as the scraper 2, the vertical The lower end of the wall 12 is provided with a single-sided cutting edge 121, and its beveled surface faces the outside of the horizontal frame 11. Like this, when the sampling frame is fixed on the ground, this single-sided cutting edge 121 can cut the soil and avoid inward extrusion. Soil, so as to avoid the distortion and disturbance of the soil, avoid the mixing of soil in different layers, and en...

Abstract

The invention discloses a soil layering scraping sampler. The sampler comprises a rectangular sampling frame and a rectangular scraping plate capable of scraping soil slidably along the sampling frame, wherein depth limiting devices are arranged on both sides of the scraping plate. The soil layering scraping sampler can control the thickness of soil layering accurately and obtain a large number of soil samples at a time, and has the advantages of simple operation and convenient carrying.

Description

technical field [0001] The invention relates to a soil layer scraping sampler, which belongs to the field of soil sampling equipment in soil science, agronomy, ecology, geography and environmental science. Background technique [0002] Soil has a very important research status in many disciplines such as soil science, agronomy, ecology, geography and environmental science. It is very important to collect scientific soil samples according to the purpose of the experiment. In order to carry out multi-item determination and obtain detailed soil profile characteristics research results at the same time, it is very meaningful to conduct stratified sampling as accurately as possible and obtain more soil samples at each level during the soil sample collection process. [0003] At present, soil drilling or destructive excavation are mostly used in the collection of soil layered samples. If soil drills are used for collection, the layering depth can generally be controlled at about ...
