[0024] A soil organic matter detection device, such as Figure 1-4 As shown, it includes: a base 100, a groove 110, a column 120, a rotating ring seat 130, a shaking box 140, a heating box 150, a mechanical arm 160, a test tube 170, a driving mechanism 200, a shaking mechanism 300, a dripping mechanism 400, a fixing mechanism 500 and an RGB color sensor; the groove 110 is opened on the base 100; the column 120 is centrally arranged in the groove 110; the inner wall of the rotating ring seat 130 is in contact with the column 120, and the outer wall of the rotating ring seat 130 is in contact with the groove 110; at least one shaking box 140 is arranged on the rotating ring seat 130; the heating box 150 is arranged in the groove 1 10; the robot arm 160 is arranged between the rotating ring seat 130 and the heating box 150; the test tube 170 is movably connected to the shaking box 140 and the heating box 150; the driving mechanism 200 is arranged in cooperation with the rotating ring seat 130; the number of shaking mechanisms 300 is consistent with that of the shaking box 140, and the shaking mechanism 300 is arranged in cooperation with the shaking box 140; a plurality of dripping mechanisms 400 are arranged on the column 120; the fixing mechanism 500 is arranged between the shaking box 140 and the test tube 170; the number of RGB color sensors is consistent with that of the shaking box 140, and the RGB color sensor is arranged in the shaking box 140.

[0025] Specifically, firstly, the test tube 170 containing the soil sample and the standard potassium dichromate-sulfuric acid solution is placed in the heating box 150 for heating. After the heating is completed, the test tube 170 is transferred to the shaking box 140 in sequence by the mechanical arm 160. Then, the driving mechanism 200 is started to drive the rotating ring seat 130 to rotate so that the test tube 170 can smoothly enter each shaking box 140. Then, the shaking box 140 is shaken by the shaking mechanism 300 to stir the sample in the test tube 170. When pure water, o-phenanthroline indicator and ferrous sulfate solution need to be added to the test tube 170, the driving mechanism 200 will drive the rotating ring seat 130 to rotate. The seat 130 and the shaking box 140 rotate to ensure that the test tube 170 is accurately aligned under the designated reagent bottle 430 for dripping.

According to the above steps, pure water, o-phenanthroline indicator and ferrous sulfate solution are added in turn until the RGB color sensor detects that the color of the solution in the test tube 170 reaches the preset chromaticity, and the flow solenoid valve 440 is immediately closed. Subsequently, the volume of reagent consumption is calculated through the precise measurement of the liquid level sensor, and finally the organic matter content is obtained.
