Full-automatic soil sample preparation system

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...

Problems solved by technology

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 the grinding device, some laboratories set up multiple sieving devices , but this will not only increase the cost but also greatly occupy the already tight space of the test bench; (3) the operation of the sieving device is not simple enough, and multiple soil sieves need to be carefully installed and sealed each time, and subsequent cleaning is time-consuming and laborious, affecting efficiency. Therefore, many laboratories prefer to use the method of "manual soil sieving" and cooperate with automatic grinding devices to complete soil sample preparation.
