[0054] The automatic sample delivery vehicle for temporarily storing hazardous waste liquid barrels of the utility model is made of corrosion-resistant materials, and the electrical parts are all explosion-proof.

[0055] Before use, the automatic sample delivery vehicle for temporarily storing hazardous waste liquid barrels of the utility model is placed in a temporary storage cabinet, and the running wheels 13 are placed on two running wheel tracks laid in the middle of the floor in the temporary storage cabinet (the cross-section of the running wheel track is: when the running wheel 13 is a cylindrical roller, the cross-section of the running wheel track is an inverted "∏"-shaped channel steel; when the running wheel 13 is a roller with a "V"-shaped annular groove on the cylindrical surface, the cross-section of the running wheel track is a "∧"-shaped triangular steel bar).

[0056] During use, when the hazardous waste liquid barrels that need to be temporarily stored are manually delivered to the automatic weighing and conveying platform at the door of the temporary storage cabinet, after completing the entry of information such as the name, weight, storage time and inventory location where the hazardous waste liquid can or needs to be placed by operating the control operation screen attached to the temporary storage cabinet, the operating system in the control operation screen automatically controls the movement of the walking components of the automatic sample delivery vehicle, so that the automatic sample delivery vehicle for temporarily storing hazardous waste liquid barrels of the utility model (hereinafter referred to as the automatic sample delivery vehicle) moves to the docking point with the automatic weighing and conveying platform; because the docking end of the automatic weighing and conveying platform is composed of four conveying components and forms a cantilever end (at this time, the hazardous waste liquid barrel is just at this place), and a gap (i.e., similar to an empty slot) is also formed between every two groups of conveying components, which can just coincide with the four gaps (i.e., similar to an empty slot) formed between the electric roller 5 and the driven roller 25, and the driven roller 25 and the adjacent driven rollers, and can form a cross. Therefore, before crossing, the operation screen can be controlled to automatically control the lifting mechanism of the automatic sample delivery vehicle to rise or fall until the plane formed by the electric roller 5 and the driven roller 25 of the electric conveying mechanism on the automatic sample delivery vehicle is slightly lower than the cantilever end of the conveying component of the automatic weighing and conveying platform, forming a cross. Then, the operation screen can be controlled to automatically control the lifting mechanism of the automatic sample delivery vehicle to rise slightly. At this time, the electric roller 5 and the driven roller 25 of the electric conveying mechanism on the automatic sample delivery vehicle hold up the hazardous waste liquid barrel on the cantilever end of the conveying component of the automatic weighing and conveying platform; then, the operating system automatically controls the movement of the walking component of the automatic sample delivery vehicle, allowing the walking wheels 13 of the automatic sample delivery vehicle to move along When the two running wheel tracks in the middle of the floor in the temporary storage cabinet move to the set inventory position, the operating system will automatically control the lifting mechanism of the automatic sample delivery vehicle to rise or fall until the plane formed by the electric roller 5 and the driven roller 25 of the electric conveying mechanism on the automatic sample delivery vehicle is flush with the shelf surface set in the temporary storage cabinet. The operating system automatically controls the electric roller 5 on the automatic sample delivery vehicle to rotate, and drives the driven roller 25 to rotate synchronously through the electric conveying driving synchronous belt 9 (similarly, other driven rollers also rotate synchronously at the same time), thereby transporting the hazardous waste liquid barrels on it to the shelf surface in the temporary storage cabinet, and the electric chain plate on it transports the set specific position for storage.

[0057] When it is necessary to extract hazardous waste liquid from the temporary storage barrel, the above sequence is reversed.

[0058] The utility model discloses an automatic sample delivery vehicle for temporarily storing hazardous waste liquid barrels, which is matched with a hazardous waste liquid temporary storage cabinet and is suitable for delivering and extracting hazardous waste liquid barrels in the temporary storage cabinet, and is also suitable for storing and retrieving hazardous waste using a standardized storage box.
