An apparatus for extracting soil organic carbon, including a rotary shaker, a first driver, a grinding and sieving device and a second driver. The rotary shaker includes a first support base, a first motor, a first support ring, a first rotating element, a heater, a weighing component and a centrifuge tube. The first driver is connected to the first rotating element to drive the first rotating element to rotate with respect to the first support ring. The grinding and sieving device includes a second support base, a second motor, a second support ring, a second rotating element, and a grinding sieve tube. The second driver is connected to the second rotating element to drive the second rotating element to rotate with respect to the second support ring.

Apparatus for extracting soil organic carbon

A soil sample digestion device, including a base, a driving mechanism, a first disk, a heating mechanism, a digestion vessel, a second disk and two liquid adding mechanisms. The driving mechanism and the first disk are mounted on the base. The heating mechanism and the digestion vessel are mounted on the first disk. The heating mechanism is configured to heat a solution in the digestion vessel. The second disk is mounted on the driving mechanism, and is configured to be driven by the driving mechanism to ascend and descend, or rotate relative to the first disk. The two liquid adding mechanisms are mounted on the second disk, and are configured for liquid addition to the digestion vessel.

Soil sample didestion device

An automatic sampling device includes a sampling unit, a traveling unit and a power supply unit. The sampling unit includes a push module, which includes a push mechanism and a turning mechanism. A plurality of collection modules are sequentially disposed and can be constrained between the turning mechanism and the push mechanism. The push mechanism is at least configured to push the plurality of collection modules to abut against the turning mechanism. The turning mechanism is at least configured to turn over a designated collection module to a material receiving position, and to enable the receiving port of the designated collection module facing towards a sample outlet of the sampling module.
