1. An automatic sampling device, comprising:
a sampling unit;
a traveling unit; and
a power supply unit;
wherein the sampling unit comprises a sampling module, a collection module, a push module and a discharge module; the sampling module is configured to be in contact with and collect a material sample; the sampling module comprises a sampling member which is movable; and the sampling member is configured to be driven by a first drive mechanism to move between a first working position and a second working position;
a sample inlet of the sampling member is configured to be in contact with and collect the material sample when the sampling member is at the first working position, and a sample outlet of the sampling member is configured to discharge the material sample when the sampling member is at the second working position; the collection module comprises a plurality of containers, a plurality of covers and a storage cylinder; each of the plurality of containers and one of the plurality of covers corresponding thereto are in an integrated or split structure; the storage cylinder is provided with a storage chamber running through the storage cylinder; the storage chamber is configured to accommodate the plurality of containers; a first end of the storage chamber is provided with a material receiving position; the material receiving position is at least configured to receive the plurality of containers; a second end of the storage chamber is provided with the push module; the plurality of containers and the plurality of covers are sequentially arranged on a motion path of the push module; the push module is at least configured to push a designated container among the plurality of containers and a cover thereof to the material receiving position, so as to enable a receiving port of the designated container to correspond to the sample outlet of the sampling module to receive the material sample collected by the sampling module; the collection module comprises a sealing mechanism; the sealing mechanism is configured to be in contact with the cover of the designated container to put the cover on the receiving port of the designated container for sealing the receiving port; and the discharge module is configured to place the designated container at a designated discharge position;
the traveling unit is connected to the sampling unit, and is configured to move the sampling unit to a specified sampling area;
the power supply unit is connected to the sampling unit and the traveling unit, and is at least configured to provide power to the sampling unit and the traveling unit;
the push module comprises a push mechanism and a turning mechanism; the plurality of containers and the plurality of covers are configured to be constrained between the turning mechanism and the push mechanism; the push mechanism is configured to push the plurality of containers and the plurality of covers to abut against the turning mechanism; and the turning mechanism is configured to turn the plurality of containers and the plurality of covers to the material receiving position in sequence and to enable a receiving port of each of the plurality of containers to face towards the sample outlet of the sampling module; and
the turning mechanism comprises a stop plate, and the stop plate is provided with a receiving groove; the stop plate is configured to move between a receiving position and a turning position; the receiving groove is configured to be at least partially in contact with the designated container when the stop plate is at the receiving position; and when the stop plate is at the turning position, the receiving groove is configured to allow the designated container therein to slide to the material receiving position, and a next designated container is configured to abut against the stop plate.
