Full-automatic soil organic matter detection device

Abstract

The invention discloses a full-automatic soil organic matter detection device. The device comprises a shell, an electric clamping jaw, a digestion bottle, a liquid adding device and a funnel assemblyheating device. The shell comprises a base and a vertical frame; the vertical frame is arranged on one side of the base; the electric clamping jaw is arranged on the vertical frame; a digestion bottlebracket for placing digestion bottles, a titration box and a digestion box are sequentially arranged at the upper end of the base; a plurality of digestion bottles are connected through a digestion bottle supporting plate and placed in the digestion bottle bracket; the liquid adding device is arranged in the titration box; the heating device is arranged in the digestion box; a funnel assembly matches the upper ends of the digestion bottles; a controller is arranged in the vertical frame; and the controller is electrically connected with the electric clamping jaw, the liquid adding device andthe heating device. The existing oil bath and sand bath are replaced by the heating device for heating digestion, the detection process is more environment-friendly, the safety in the whole experimentprocess is improved through mechanical automatic operation, the working efficiency is improved, and the time is saved.

Description

technical field [0001] The invention relates to the technical field of soil organic matter detection, in particular to a fully automatic soil organic matter detection device. Background technique [0002] The existing methods for measuring soil organic matter mainly use oil baths and sand baths as digestion devices, manually add reagents, observe the color change of the titration process with human eyes to judge the end point, and then use a calculator to calculate the experimental data through formulas to obtain the determination result. [0003] The whole experimental process is mainly manual operation, which is time-consuming and labor-intensive, and the oil bath device is used to pollute the air, emitting a pungent smell, and the manual operation error is relatively large, resulting in poor stability of the experimental data and large data fluctuations, which reduces the accuracy of the experimental data sex. Contents of the invention [0004] The present invention a...
