When the upper and lower parts of the sampling box 6 are combined together, the upper and lower parts of the externally threaded tube 9 form a tube with a thread on the outer circumference, and are connected to the sampling inlet 100. The inside of the box 6 is connected, the threads on the external threaded tube 9 are connected to the internal threaded tube 10, the internal threaded tube 10 is connected to one side of the piston cylinder 11, and the other side of the piston cylinder 11 is connected to the air storage cylinder 12. The air storage cylinder 12 is filled with high-pressure nitrogen. The first piston 13 is airtightly slidably installed in the piston cylinder 11. The outer periphery of the first piston 13 is airtightly slidably matched with the inner wall of the piston cylinder 11. A vent hole 14 is provided on the first piston 13. A first T-shaped rod 15 is fixedly installed at one end of the first piston 13. One end of the first T-shaped rod 15 passes through the piston cylinder 11 and extends to the outside. The first T-shaped rod 15 slides airtightly with the inner wall of the reserved hole on the piston cylinder 11 The first piston 13 is connected to the inner wall of the piston cylinder 11 through the first spring 16, and the first spring 16 is mounted on the first T-shaped rod 15. One end of the first spring 16 is fixedly connected to the first piston 13, and the other end of the first spring 16 is fixedly connected to the inner wall of the piston cylinder 11. Under the action of the first spring 16, the vent hole 14 is misaligned with the reserved holes on both sides of the piston cylinder 11, and the cavity in the piston cylinder 11 away from the side of the first spring 16 is filled with gas that is easily expanded when heated. A heat-conducting rod 17 is fixedly installed on the side of the piston cylinder 11 away from the first T-shaped rod 15, and the end of the heat-conducting rod 17 away from the piston cylinder 11 extends to the outside of the outer sleeve 1. The present invention has a simple structure and an ingenious design. When the gas in the piston cylinder 11 expands due to heat and causes the vent hole 14 to connect the sampling box 6 and the gas storage cylinder 12, the high-pressure nitrogen in the gas storage cylinder 12 is sprayed into the sampling box 6, which can spray out the initially sampled molten steel containing more impurities. After the high-pressure nitrogen is discharged, the air pressure in the sampling box 6 returns to normal, and as the auxiliary gun is inserted into the molten steel, new molten steel without impurities enters the sampling box 6 to complete the sampling. This invention can meet actual needs and is suitable for promotion.When in use, insert the end with the cap 8 into the molten steel. The cap 8 breaks the slag when entering the molten steel, and at the same time protects the temperature measuring component 5 and the sampling box 6. After the cap 8 melts, the temperature measuring component 5 measures the temperature of the molten steel. As the auxiliary gun probe goes deeper, the molten steel burns the slag blocking cap 7, and the molten steel enters the sampling box 6. The auxiliary gun is inserted into the molten steel. After the end of the heat conducting rod 17 located outside the outer sleeve 1 contacts the molten steel, the heat of the molten steel is quickly transferred to the piston cylinder 11, and further to the gas that is easily expanded when heated. The gas that is easily expanded when heated expands after contacting high temperature, thereby pushing the first piston 13 to move, so that the vent hole 14 is connected The sampling box 6 and the gas cylinder 12 are connected, and the high-pressure nitrogen in the gas cylinder 12 is sprayed into the sampling box 6 to spray out the molten steel containing more impurities in the preliminary sample. After the high-pressure nitrogen is discharged, the air pressure in the sampling box 6 returns to normal, and as the auxiliary gun is inserted into the molten steel, new molten steel without impurities enters the sampling box 6 to complete the sampling; the first T-shaped rod 15 is pulled, and the first T-shaped rod 15 drives the first piston 13 to move, so that the gas cylinder 12 is connected with the vent hole 14. At this time, high-pressure nitrogen can be introduced into the gas cylinder 12. After the high-pressure nitrogen is introduced, the first T-shaped rod 15 is loosened, and the internal threaded tube 10 is installed on the external threaded tube 9.

[0018] Specifically, if Figure 4 As shown, in the present embodiment, a second piston 20 is airtightly slidably installed in the air storage cylinder 12, and the second piston 20 is elastically connected to the inner wall of the air storage cylinder 12 through a second spring 21, and the second spring 21 is in a stretched state. A limiting mechanism for limiting its movement is provided on the second piston 20, and the limiting mechanism includes a second T-shaped rod 22, and the second T-shaped rod 22 is slidably installed in the sliding sleeve 23. The outer periphery of the second T-shaped rod 22 is in sliding contact with the inner wall of the sliding sleeve 23, and the second T-shaped rod 22 is connected to the sliding sleeve 23 through a third spring 24, and the third spring 24 is sleeved on the outer periphery of the second T-shaped rod 22, one end of the third spring 24 is fixedly connected to the second T-shaped rod 22, and the other end of the third spring 24 is fixedly connected to the sliding sleeve 23, and a slot 25 is provided on the inner wall of the air storage cylinder 12 corresponding to the second T-shaped rod 22, and the second T-shaped rod 22 is plugged into and matched with the slot 25, and a bimetallic strip 26 is fixedly installed on the air storage cylinder 12, and one end of the bimetallic strip 26 is against the second T-shaped rod 22. When molten steel enters the sampling box 6, the temperature inside the sampling box 6 and the gas storage cylinder 12 increases, and the bimetallic strip 26 bends due to the heat, thereby driving the second T-shaped rod 22 to move toward the center of the second piston 20. When the second T-shaped rod 22 disengages from the slot 25, the second piston 22 moves backward under the action of the second spring 21, reducing the pressure inside the sampling box 6, thereby sucking the molten steel into the sampling box 6, thereby speeding up the sampling process.

[0019] Specifically, Figure 4As shown, the limiting mechanism described in this embodiment is provided with two left and right limiting mechanisms, and the two limiting mechanisms are symmetrically distributed about the center of the second piston 20. The two left and right limiting mechanisms are provided, so that the limiting of the second piston 20 is more stable.

[0020] Further, such as Figure 1 , Figure 5 As shown, the refractory sand head 4 of this embodiment is provided with an annular groove 40, and the cap 8 is provided with a protrusion 41 that fits with the annular groove 40, with the protruding side of the protrusion 41 facing inward, and the protrusion 41 is stuck in the annular groove 40. The cap 8 is installed on the refractory sand head 4 by the protrusion 41 being stuck in the annular groove 40 on the refractory sand head 4.

[0021] Furthermore, if Figure 1 , Figure 5 As shown, the cap 8 of this embodiment includes an annular portion 50 and an arc portion 51. Several arc portions 51 are provided and are respectively hinged on the annular portion 50. Two adjacent arc portions 51 are close together. Baffles 52 are respectively fixedly installed on the arc portions 51. One side of the baffle 52 is respectively provided with elastic sheets 53 for contact and cooperation. The elastic sheets 53 are in a compressed state. The left ends of several arc portions 51 are provided with a fixing mechanism to limit them from being bounced open. After the probe is inserted into the molten steel, the left end of the arc portion 51 contacts the molten steel first and the temperature rises quickly, and it will melt first. The fixing mechanism can no longer limit the arc portion 51. Under the action of the elastic force of the elastic sheet 53, the baffle 52 and the arc portion 51 are bounced outward, so that they are away from the sampling box 6, reducing the possibility of the cap 8 entering the sampling box 6 after melting, and improving the purity of the sampling.

[0022] Furthermore, if Figure 1 , Figure 6 As shown, the fixing mechanism of this embodiment includes an annular plate 60, which is located on one side of the cap 8. The annular plate 60 is fixed with stoppers 61 corresponding to the arc-shaped portions 51. Stopper holes 62 are respectively provided on the arc-shaped portions 51. The stoppers 61 are plugged into the corresponding stopper holes 62. A stopper cover 63 having an interference fit with the center hole of the annular plate 60 is provided on the other side of the cap 8. The boss on the stopper cover 63 has an interference fit with the center hole of the annular plate 60. When the stopper blocks 61 on the annular plate 60 are inserted into the corresponding stopper holes 62, and then the stopper cover 63 is inserted into the center hole of the annular plate 60, the arc-shaped portions 51 cannot be bounced open by the elastic sheet 53.

[0023] Furthermore, if Figure 1 , Figure 3As shown, in the present embodiment, a heat-conducting rod 18 is fixedly installed in the piston cylinder 11, and the heat-conducting rod 18 is located in the cavity with the gas that is easily expanded when heated. The heat-conducting rod 18 is fixedly connected to the heat-conducting rod 17, and the outer periphery of the heat-conducting rod 18 is fixedly connected to the inner wall of the reserved hole on the piston cylinder 11. One side of the heat-conducting rod 17 is fixedly connected to one end of the heat-conducting rod 18. The heat-conducting rod 17 and the heat-conducting rod 18 are both made of materials with high thermal conductivity, and the heat-conducting rod 17 and the heat-conducting rod 18 are both made of high-temperature resistant materials. The heat-conducting rod 18 can transfer the heat of the heat-conducting rod 17 to the gas that is easily expanded when heated more quickly, thereby accelerating the movement of the first piston 13.
