Although the grinding device and screening device have realized the instrumentation of soil sample preparation, improved efficiency and reduced labor intensity and dust, there are still the following disadvantages: (1) Although the grinding device can complete the grinding of up to 4 samples at the same time, However, the sieving device can only complete the sieving of a single sample at a time, and the efficiency of sample preparation is limited by the sieving device, which cannot achieve real high efficiency; (2) In order to match the efficiency of th

Embodiment 1
[0033] Example 1: See attached figure 2 , A fully automatic soil sample preparation system, which includes: grinding and grinding mechanism 1, screening mechanism 2, sample loading mechanism 3, manipulator 4, cleaning assembly 5. In addition, the system can be optionally expanded with a drying and heating mechanism 6, weighing Heavy mechanism 7, laser particle size analysis mechanism 8 and X-ray fluorescence spectrometer 9;
[0034] The drying and heating mechanism 6 is used for drying the soil sample;
[0035] The grinding and grinding mechanism 1 is used to grind the dried soil sample;
[0036] The screening mechanism 2 is used to screen the ground soil sample;
[0037] The weighing mechanism 7 is used to weigh the sieved soil sample;
[0038] The sample loading mechanism 3 is used to sample the soil samples after being sieved in quarter method;
[0039] Manipulator 4 is used to transfer soil samples;
[0040] The cleaning component 5 is used to clean the container containing the soil...
Embodiment 2
[0043] In Example 2, on the basis of Example 1, the specific structures of the grinding and grinding mechanism 1, the screening mechanism 2, the sample loading mechanism 3, the manipulator 4, the cleaning assembly 5, the drying and heating mechanism 6, and the weighing mechanism 7 are defined :
[0044] See attached Picture 8 , The drying and heating mechanism 6 includes: a drying cylinder 61 and a radiant heating device 62; during drying, the drying cylinder 61 itself rotates and the inside is in a negative pressure state, which can accelerate the evaporation of moisture and increase the drying speed; at the same time, the radiant heating device 62 can eliminate the negative pressure As a result, the gas in the cylinder absorbs heat when the gas volume expands, resulting in a rapid decrease in sample temperature. Maintain the sample in the drying cylinder 61 within a reasonable range between the normal room temperature and the upper limit of the soil sample preparation temperatu...

Abstract
The invention relates to the technical field of soil sample preparation, in particular to a soil sample preparation system. The full-automatic soil sample preparation system comprises a crushing and grinding mechanism, a screening mechanism, a sample loading mechanism, a manipulator and a cleaning assembly, wherein the crushing and grinding mechanism is used for grinding a soil sample; the screening mechanism is used for screening the ground soil sample; the sample loading mechanism is used for carrying out quartering sample loading on the screened soil sample; the manipulator is used for transferring the soil sample; and the cleaning assembly is used for cleaning a container accommodating the soil sample. The full-automatic soil sample preparation system realizes automation of the soil sample preparation process, effectively avoids the cross contamination of samples, improves the sample preparation environment, reduces the labor intensity, and improves the sample preparation efficiency; and the process operation of the full-automatic soil sample preparation system has compliance consistency, and full-process automation of soil sample preparation is realized.
Description
Technical field [0001] The invention relates to the technical field of soil sample preparation, in particular to a soil sample preparation system. 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. Such as figure 1 As shown, the traditional soil sample preparation process includes the steps of sampling, removing mixed bricks, lime nodules, rhizome animal and plant residues and other foreign matter in the soil, air drying, coarse grinding, fine grinding, weighing and bottling. The preparation of soil samples in a purely manual manner has disadvantages such as long sample processing cycles, large sample storage, low sample preparation efficiency, and easy cross-contamination of samples. At present, some devices for soil sample preparation are launched on the market in order to improve the efficiency of sample preparation. The soil sample preparation device is mai...
