Description
Technical Field
The invention relates to the technical field of soil sample preparation, in particular to a device for separating a soil sample.
Background
The soil sample preparation refers to the process of uniformly mixing, drying, grinding and sieving the soil sample after the soil sample is collected from the field. As shown in fig. 1, the conventional soil sample preparation process includes: sampling, removing foreign matters such as bricks, lime concretions, rhizome animal and plant residues and the like mixed in soil, air-drying, coarse grinding, fine grinding, weighing, bottling and the like. At present, according to the relevant requirements of national environmental protection industry standard HJ/T166-doped 2004 soil environmental monitoring technical Specification 'eighth chapter sample preparation', a quartering method is adopted to sort soil samples in the processes of soil sample primary selection, coarse grinding, fine grinding, bottling and the like. According to the traditional soil sample preparation method, quartering is realized manually, a stacking cone quartering method is usually adopted for quartering, soil is stacked into a cone shape, and then a ruler is used for rotating to lay the cone into a cake shape; drawing a cross line by using a ruler; taking soil samples of two fan-shaped parts at opposite angles; the tools needed to be used in the soil sample screening and weighing processes mainly comprise: nylon sieves with different pore diameters, white porcelain mortar, electronic scales and various auxiliary tools. The traditional soil sample preparation process is purely manual operation, and has the problems of large workload, long period, high requirement on personnel quality, low sample preparation efficiency and the like.
Disclosure of Invention
The purpose of the invention is: in order to improve the preparation efficiency of the soil sample, a sample splitter for splitting the soil sample is provided.
The technical scheme of the invention is as follows: a sample splitter for separating 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 is divided into four or even number of symmetrical areas larger than four by a grid penetrating through the center of the main body, one half of the areas are closed, and the areas with closed bottom surfaces are arranged at intervals.
When the soil samples are normally distributed and naturally fall along the central line of the sample separation device, half of the soil samples fall through the unsealed area, and the other half of the soil samples are uniformly intercepted into the area with the closed bottom, so that the soil samples are uniformly separated.
The sample separating device is directly arranged in the vibrating screen, and the screening and sample separating functions of the vibrating screen can be realized. Further, the vibrating screen structure includes: the filter screen is embedded into the outer frame; in order to increase the sample screening efficiency, the cross section of the filter screen can be in an inverted cone structure, and grinding balls are arranged in an annular surface between the filter screen and the outer frame; when vibrating, the grinding ball is vibrated for the second time by the elasticity of the filter screen, and the filter screen is bounced when falling and rebounding, so that the vibration effect is strengthened.
The sample separating device is arranged at the inlet of the funnel, and the outlet of the funnel is opposite to the sample container, so that the sample separating and subpackaging functions can be realized simultaneously.
The sample separating device is arranged in the receiving hopper, so that the sample separating and sampling functions can be realized; further, connect the hopper setting on weighing platform, the bottom that connects the hopper is relative with the vibration screen cloth.
Has the advantages that: the invention realizes the uniform separation of the soil sample, the properties of the soil sample and the powdery sample retained in the sample separating device are kept uniform and consistent through the sample separating device and are representative with each other, the separation result meets the national standard, and the preparation phase ratio of the soil sample is improved.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
Example 1: referring to fig. 2, a sample splitter for separating soil samples, a sample splitter 1 has a circular frame-shaped or square frame-shaped main body, the interior of the sample splitter is divided into four or even number of symmetrical regions greater than four by a grating penetrating through the center of the main body, a half of the regions are closed, and the regions with closed bottom surfaces are arranged at intervals. In this example, in order to perform the quartering method of the soil sample, the interior of the sample dividing device 1 is divided into four symmetrical sections.
When the soil samples are normally distributed and naturally fall along the central line of the sample separation device 1, half of the soil samples fall through the unsealed area, and the other half of the soil samples are uniformly intercepted into the area with the closed bottom, so that the soil samples are uniformly separated.
Example 2: referring to fig. 3, on the basis of embodiment 1, the sample separation device 1 is directly arranged in the vibrating screen 2, so that the screening and sample separation functions of the vibrating screen 2 can be realized.
Referring to fig. 4, further, the vibrating screen 2 has a structure including: an outer frame 21 and a filter net 22 fitted into the outer frame 21; in order to increase the sample screening efficiency, the cross section of the filter screen 22 can be in an inverted cone structure, and a grinding ball 23 is arranged in the annular surface between the filter screen 22 and the outer frame 21; during vibration, the grinding balls 23 are vibrated for the second time by the elasticity of the filter screen 22, and when falling and rebounding, the grinding balls bounce against the filter screen 22, so that the vibration effect is strengthened.
Example 3: referring to fig. 5, on the basis of embodiment 1, the sample separating device 1 is arranged at the inlet of the funnel 3, and the outlet of the funnel 3 is opposite to the sample container, so that the functions of separating samples and subpackaging can be realized simultaneously.
