Abstract: 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.

Abstract: 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.

Abstract: A soil sample purification device includes a liquid supplying mechanism and a liquid feeding mechanism. The liquid supplying mechanism includes fluid injection channels, a fluid collector, a mounting plate and fluid supplying boxes. The fluid supplying boxes are movably connected to the mounting plate, and are configured to respectively carry a single fluid material. The fluid collector is provided with a fluid collecting chamber, which is communicated with the fluid supplying boxes respectively via the fluid injection channels. The fluid supplying boxes are configured to move between a fully-loaded position and an unloaded position. The liquid feeding mechanism includes a liquid feeding box and a plugging member. The plugging member is movably provided on the liquid feeding box, and can move in a specified direction to block the outlet channel, or move in a direction opposite to the specified direction to unblock the outlet channel.
