[0023] The sampling mechanism comprises: a sampling barrel 5, which is located below the base 1 and is clamped by an adjustment mechanism. A limiting ring 16 is also provided on the surface of the sampling barrel 5 for preventing the sampling barrel 5 from being separated from the inside of the mounting ring 6. Two sampling movable plates 21 that can be opened and closed are provided on the bottom surface of the sampling barrel 5. A weighting plate is fixedly installed on the upper surface of the sampling movable plate 21. An axis body is provided at the connection between the sampling movable plate 21 and the sampling barrel 5, and the sampling movable plate 21 can rotate toward one side of the inside of the sampling barrel 5 through the axis body.

[0025] In this embodiment, the base serves as the supporting structure of the entire robotic arm, and a sliding table is provided on the upper surface. The sliding table drives the device to move smoothly through rollers to meet different experimental requirements.

[0026] The robot body is driven by the electric push rod in the installation slot and moves horizontally on the bottom of the base to meet the sampling needs of different positions. The robot body is designed as a multi-segment structure. Each segment is connected by a rotating shaft. Each segment can be controlled by a signal to rotate around the rotating shaft to achieve multi-angle adjustment of the robot arm.

The connecting rod moves up and down in the limiting tube through the telescopic hole to drive the cover plate to open and close, thereby ensuring the sealing of the internal molten steel. When the sampling tube is dumped for unloading, it can be opened with gravity to dump the internal molten steel. The design of the weighting plate and the weighting block increases the gravity of the sampling tube and the cover plate, ensuring that the sampling tube can sink smoothly into the molten steel.

The threaded barrel engages with the threaded rod through the internal thread. The driving motor controls the rotation of the threaded rod, thereby driving the threaded barrel to rise and fall. When the driving motor is working, the pulling rope is tightened or loosened through the transmission of the threaded rod and the threaded barrel, thereby driving the sampling barrel to tilt or stand upright, completing the sampling and sample removal process.
