[0002] When soil organic matter is determined, the following operation is needed according to the detection standard of NY / T 1121.6-2006: "... shake up and insert a glass funnel into each test tube. Insert the test tubes into the wire cage one by one, and then sink the wire cage into the oil bath pot which has been heated to 185-190 DEG C on the electric furnace, so that the liquid level in the tube is lower than the oil level. After being put in, the oil bath temperature drops to 170-180 DEG C, and the solution in the test tube is boiled. At this time, the electric furnace temperature must be controlled, so that the solution does not boil violently. In the process, the wire cage can be shaken in the oil bath pot several times to make the liquid temperature uniform and maintain at 170-180 DEG C. After 5 min ± 0.5 min, the wire cage is taken out of the oil bath pot, cooled for a moment, and the oil (wax) liquid on the outside of the test tube is wiped off...", wherein the test tube needs to be placed on the test tube rack, immersed in the heated oil, shaken, taken up and the oil liquid on the outside of the test tube is wiped off.

The electric telescopic rods are electrically connected to the control system of the oil bath device body or controlled by a separate control system, so that the telescopic rods are controlled to rise and fall simultaneously by the control system.

[0012] Further, the connecting rods are respectively provided with two connecting rods, which are fixedly connected to the two ends of the corresponding insertion slots.

[0013] Preferably, the height of the inner cavity of the insertion slot is greater than the thickness of the insertion piece, and the distance between the vertical side walls of the two insertion slots is greater than the distance between the outer edges of the two insertion pieces. In this way, the test tube rack can be placed on the vibrator as a whole, the vibrator can be fully utilized to vibrate the test tube, and the test tube rack can be prevented from generating large displacement.

[0014] Due to the adoption of the above technical solutions, the present application has the following advantages:

[0015] The present application can realize the vibration and mixing of the test tube by installing a vibrator in the oil groove of the existing oil bath device, can remove the oil stains on the test tube when the test tube is extracted by installing a sponge layer on the test tube rack, and can realize the automatic lifting of the test tube rack by installing an insertion piece on the test tube rack body, installing electric telescopic rods and insertion slots on both sides of the oil bath device body, etc. The above settings can realize automatic lifting, mixing and oil stain removal operations.
