[0035] In another embodiment, the card member 7 includes a fixing ring 71, a sleeve 72, clamping blocks 73 and a thrust spring 74. The fixing ring 71 is fixedly sleeved on one end of the mounting rod 4 close to the frame body 3. One end of the sleeve 72 is fixedly connected to the fixing ring 71. The sleeve 72 is annular. A gap for the sampler 100 to extend into is provided between the inner diameter of the sleeve 72 and the side wall of the mounting rod 4. The thickness of this gap is slightly larger than the wall thickness of the connecting paper tube 102 of the sampler 100. An installation cavity is formed around the inside of the sleeve 72. Strip-shaped holes communicating with the installation cavity are formed on the inner wall of the sleeve 72. There are multiple strip-shaped holes, which are arranged around the central axis of the sleeve 72.

[0036] A fixing frame 9 is arranged on the frame 1. The fixing frame 9 is located on one side of the rotating frame 2. A lead screw 10 is rotatably arranged inside the fixing frame 9 along its length direction. Two guide rods 11 are fixedly arranged inside the fixing frame 9. The two guide rods 11 are respectively located on both sides of the lead screw 10. A motor reducer 12 is arranged on the frame 1. The output shaft of the motor reducer 12 is connected to the end of the lead screw 10. A nut and two first sliders are fixedly arranged at the bottom of the conveying plate 5. The nut is sleeved on the lead screw 10. The two first sliders are respectively slidably sleeved on the two guide rods 11 to guide the sliding of the conveying plate 5.

The baffle 6 is located at the end of the limiting block 8 away from the rotating frame 2 to play a role in pushing the sampler 100.

[0037] The rack 1 is further provided with a cantilever platform 13. The cantilever platform 13 is located below the frame body 3. A stripping hole 14 is formed in the cantilever platform 13. A collection box 15 is arranged on the rack 1. The collection box 15 is located below the stripping hole 14 and is used for collecting steel samples to avoid contamination. The scraper 16 can be fixed on the rack 1 or rotatably arranged on the rack 1 by a second motor. The scraper 16 is located on one side of the cantilever platform 13 close to the conveying plate 5. A placement groove 17 is arranged below the scraper 16. The scraper 16 can rotate, and when the edge rotates to the connection part of the paper shell 101 of the sampler 100 and the connecting paper tube 102, it drives the sampler 100 to be pulled out from the clamping part 7; or the scraper 16 is fixed, and the connection part of the paper shell 101 of the sampler 100 and the connecting paper tube 102 is stuck below the scraper 16. The second air cylinder 22 contracts upward, driving the mounting rod 4 to move away from the scraper 16, so that the scraper 16 pulls the sampler 100 out of the clamping part 7. The design is reasonable and the practicability is strong.

[0038] A handle can also be arranged on the rack 1. Universal wheels (not shown in the figure) are arranged at the bottom of the rack 1 to facilitate the movement of the sampling device. When not in use, it can be pushed away to avoid being in a high-temperature state for a long time. It is practical and reliable.

[0039] During use, first push the sampling device in front of the ladle, so that the side of the mounting rod 4 away from the conveying plate 5 is close to the ladle. Place a sampler 100 between the two limit blocks 8. The end of the slag retaining cap of the sampler 100 contacts the baffle 6. One end of the connecting paper tube 102 of the sampler 100 faces the rotating frame 2. At this time, the first motor drives the rotating frame 2 to rotate, driving the frame 3 and the mounting rod 4 thereon to rotate to the horizontal direction, and the mounting rod 4 is beside the conveying plate 5. The connecting paper tube 102 of the mounting rod 4 and the sampler 100 are coaxial. At this time, the motor reducer 12 drives the conveying plate 5 to slide towards the end close to the mounting rod 4, and sleeved the connecting paper tube 102 of the sampler 100 on the mounting rod 4. Under the further push of the baffle 6, the connecting paper tube 102 of the sampler 100 extends into the gap between the clamping block 73 and the mounting rod 4 along the inclined surface of the clamping block 73. The thrust spring 74 gives the clamping block 73 a radial thrust, so that the clamping block 73 clamps the connecting paper tube 102 of the sampler 100. Then the rotating frame 2 rotates, driving the frame 3, the mounting rod 4 and the sampler 100 to rotate to the other side. The first cylinder 20 drives the frame 3, the mounting rod 4 and the sampler 100 to slide on the rotating frame 2, so that the mounting rod 4 and the sampler 100 are above the ladle. Then the second cylinder 22 extends, driving the sliding block 21 to slide in the chute of the frame 3, so that the mounting rod 4 and the sampler 100 thereon extend into the ladle. After standing for 3 seconds, the slag retaining cap of the sampler 100 melts, and the molten steel enters the sampling box to complete the sampling. Then the second cylinder 22 drives the sliding block 21 to slide, retracts the mounting rod 4 and the sampler 100. After the taken molten steel solidifies, the motor reducer 12 drives the rotating frame 2 to rotate, so that the mounting rod 4 is in the vertical state. At the same time, the first cylinder 20 drives the frame 3 to slide on the rotating frame 2, so that the mounting rod 4 slides directly above the cantilever platform 13, making the center of the sampler 100 align with the center of the stripping hole 14. The second cylinder 22 drives the sampler 100 to move quickly towards the stripping hole 14. The coated sand shell at the bottom of the sampler 100 impacts the cantilever platform 13. Under the action of the impact force and inertia, the sample in the sampling box is stripped from the sampling box and falls into the collection box 15 through the stripping hole 14 to complete the stripping of the sample. After the sample stripping is completed, the rotating frame 2 rotates, so that the mounting rod 4 and the sampler 100 rotate below the scraper 16. The scraper 16 pulls out the sampler 100 from the clamping member 7 to complete a sampling cycle.
