Embodiment 1

[0018] Embodiment 1: see attached figure 2 , a sample divider for sorting soil samples, the main body of the sample divider 1 is a circular frame-shaped or square frame-shaped structure, and its interior is divided into four or greater than four even-numbered symmetrical area, in which half of the bottom surfaces are closed, and the areas with closed bottom surfaces are arranged at intervals. In this example, in order to realize the quartering of the soil sample, the inside of the sampling device 1 is divided into four symmetrical intervals.

[0019] When the soil samples are normally distributed and fall naturally along the centerline of the sampling device 1, half of the soil samples fall through the unclosed area, and the other half of the soil samples are evenly retained in the closed area at the bottom, so as to realize the sampling of the soil samples. Evenly separated.

Embodiment 2

[0020] Embodiment 2: see attached image 3 , On the basis of Embodiment 1, the sample dividing device 1 is directly arranged in the vibrating screen 2, so that the function of sieving and dividing samples of the vibrating screen 2 can be realized.

[0021] See attached Figure 4 Further, the structure of the vibrating screen 2 includes: an outer frame 21 and a filter screen 22 embedded in the outer frame 21; in order to increase the sample screening efficiency, the cross section of the filter screen 22 can be an inverted cone structure, and the filter screen 22 Grinding balls 23 are arranged in the annular surface between the outer frame 21; when vibrating, the grinding balls 23 are subjected to secondary vibration by the elastic force of the filter screen 22, and bounce against the filter screen 22 when falling and rebounding to strengthen the vibration effect.

Embodiment 3

[0022] Embodiment 3: see attached Figure 5 , On the basis of Example 1, the sample dividing device 1 is arranged at the inlet of the funnel 3, and the outlet of the funnel 3 is opposite to the sample loading container, so that the functions of sample dividing and packaging can be realized simultaneously.

Abstract

The invention relates to the technical field of soil sample preparation, in particular to a device for separating soil samples. A sample splitter for sorting soil samples is characterized in that a sample splitting device main body is of a circular frame-shaped or square frame-shaped structure, the interior of the sample splitting device main body is divided into four or more than four even numberof symmetrical regions by a grid penetrating through the center of the main body, bottom surfaces of half of the regions are sealed, and the regions with the sealed bottom surfaces are arranged at intervals. The sample splitter realizes uniform separation of the soil samples, the properties of the soil samples and that of powdery samples intercepted in the sample splitting device are kept uniform, consistent and mutually representative by means of the sample splitting device, the separation result meets the national standard, and the preparation phase rate of the screened soil samples is increased.

Description

technical field [0001] The invention relates to the technical field of soil sample preparation, in particular to a device for dividing soil samples. Background technique [0002] Soil sample preparation refers to the process of mixing, drying, grinding and sieving soil samples after they are collected from the field. like figure 1 As shown, the traditional soil sample preparation process includes: sampling, removal of foreign matter such as bricks, lime concretions, rhizome animal and plant residues mixed in the soil, air drying, coarse grinding, fine grinding, weighing and bottling, etc. At present, in accordance with the relevant requirements of the national environmental protection industry standard HJ / T 166-2004 "Technical Specifications for Soil Environment Monitoring" "Chapter 8 Sample Preparation", in the process of soil sample primary selection, coarse grinding, fine grinding, bottling, etc. Soil samples were sorted by quartering method. The traditional soil sampl...
