At this time, a sufficient number of refractory bricks are placed on the placing plate 7 in the uppermost layer. Then the second driving element 15 drives the pull plate 16 to move toward the connecting and separating area. When the second inclined surface contacts the third inclined surface on the first protrusion 21, it will push the inner plate 20 to move upward against the elastic force of the third spring 19. When the inner plate 20 moves to the top of the recessed area, the inner plate 20 enters the recessed area under the action of the elastic force of the third spring 19. At this time, the second driving element 15 drives the pull plate 16 to move away from the connecting and separating area. At this time, the inner rod 10 is pulled through the first protrusion 21 and the inner plate 20 to move toward the opening slot 26 against the elastic force of the first spring 17. After the inner rod 10 enters the opening slot 26, the plug rod 29 has entered the closed area. At this time, the second driving element 15 drives the pull plate 16 to move toward the connecting and separating area. At this time, the second inclined surface pushes the second protrusion 22 to move a distance against the fourth spring 25. When the fourth spring 25 is compressed too much, the second inclined surface will make the inner plate 20 move upward against the elastic force of the third spring 19. At this time, the inner plate 20 can finally move to the third inclined surface of the second protrusion 22. At this time, the second protrusion 22 is restored to its original position under the action of the fourth spring 25. The second driving element 15 drives the pull plate 16 to move away from the connecting and separating area again. The bottom of the inner plate 20 will contact the third inclined surface on the second protrusion 22 and make the second protrusion 22 move toward the first protrusion 21 against the elastic force of the fourth spring 25. When the distance between the first protrusion 21 and the second protrusion 22 is less than the width of the bottom of the inner plate 20, the inner plate 20 will pass through the third inclined surface on the second protrusion 22, move along the surface of the second protrusion 22 and the surface of the first protrusion 21, and finally move to the outside of the first protrusion 21 and be restored to its original position by the second driving element 15. After completion, the hub motor is started to drive the placing plate 7 to move into the tunnel kiln 9. In the tunnel kiln 9, since the plug rod 29 is inserted into the closed area in a vertical state, when the lifting part lifts the placing plate 7 upward, the inner rod 10 will move away from the opening slot 26, and at the same time, the plug rod 29 will also move away from the closed area. Here, it needs to be noted that during the process of the placing plate 7 being located in the tunnel kiln 9, the lifting part and the second connecting and separating part will ensure that the state of the inner rod 10 remains unchanged, so that when the tunnel kiln 9 completes the baking and drying, the placing plate 7 moves downward under the action of the lifting part, the inner rod 10 can enter the opening slot 26, and the plug rod 29 can be reinserted into the closed area. After the baking and drying is completed, the placing plate 7 finally moves to the supporting plate 3 again. At this time, the inner rod 10 enters the opening slot 26,The insertion rod 29 is also reinserted into the closed area, and then it can be moved to the top of the concave plate 6 under the driving of the wheel hub motor. At this time, the refractory bricks on the placement plate 7 can be removed first, and then the first driving element 8 drives the concave plate 6 to move upward, and after the placement plate 7 is in contact with the bottom of the concave plate 6, the first driving element 8 continues to drive the concave plate 6 to move upward by a distance, so that the concave plate 6 drives the placement plate 7 to move upward, and finally the insertion rod 29 is separated from the closed area. At this time, under the action of the first spring 17, the inner rod 10 will return to the original position. During or after the inner rod 10 returns to the original position, the lifting assembly moves the bottom of the insertion rod 29 to the inside of the insertion hole 28,

[0123] As an embodiment, as shown in Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 14 The lifting assembly comprises:

[0124] The side block 32 provided on one side of the insertion rod 29, part of the insertion rod 29 is located in the recessed area, and the side surface of the first protrusion 21 located in the recessed area is provided with a side surface groove 30, and the side block 32 is in sliding connection with the side surface groove 30, and when the inner plate 20 enters the recessed area, downward pressure is applied to the insertion rod 29;

[0125] The second inner cavity 31 provided in the inner rod 10, the second inner cavity 31 is in communication with the side surface groove 30;

[0126] The first inner block 33 in sliding connection with the first inner groove 34 provided at the bottom of the second inner cavity 31 and the hinged rod 35, one end of the hinged rod 35 is hinged to the upper surface of the first inner block 33, and the other end of the hinged rod 35 is hinged to the lower surface of the side block 32;

[0127] The adjusting member for applying an external force to the first inner block 33 towards the insertion rod 29, so as to push the bottom of the insertion rod 29 into the insertion hole 28 after the inner plate 20 is separated from the recessed area.

[0128] In this embodiment, before the inner plate 20 enters the enclosed area, the bottom of the insertion rod 29 is completely located in the insertion hole 28 due to the external force exerted by the adjusting member. During the process of the inner plate 20 entering the enclosed area, the insertion rod 29 overcomes the external force exerted by the adjusting member under the pushing of the third spring 19, so that the insertion rod 29 moves downward and finally the bottom of the insertion rod 29 extends outside the insertion hole 28. At this time, the external force of the adjusting member maintaining the insertion rod 29 is destroyed, so that the insertion rod 29 will not return to the original position until the inner rod 10 returns to the original position or after the inner rod 10 returns to the original position, the adjusting member makes the first inner block 33 move towards the insertion rod 29 by external force, at this time the insertion rod 29 will finally return to the original position.

[0129] As an implementation form, as shown in Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 13 The adjusting member comprises:

[0130] The first electromagnet 61 arranged in the first inner block 33 and the second electromagnet 62 arranged in the side block 32 are opposite to each other when the first inner block 33 is opposite to the side block 32, and at this time, the hinged rod 35 is inclined outward from top to bottom;

[0132] The push rod 63 for inserting into the push hole 60 and pushing the first inner block 33.

[0133] Here, when the first inner block 33 is opposite to the side block 32, the mutual attraction force between the first electromagnet 61 and the second electromagnet 62 is generated at this time, so that the bottom of the insertion rod 29 is maintained in the insertion hole 28. After the inner plate 20 enters the enclosed area, the inner plate 20 will exert an external force on the insertion rod 29, so that the balance of the attraction force between the first electromagnet 61 and the second electromagnet 62 is broken, so that the insertion rod 29 moves downward, and the first inner block 33 is misaligned with the side block 32. Therefore, after the inner plate 20 leaves the enclosed area, the insertion rod 29 will not return to the original position until the inner rod 10 returns to the original position. After the inner rod 10 returns to the original position, the operator can insert the push rod 63 into the push hole 60, and push the first inner block 33 to return to the original position by the push rod 63. At this time, the first inner block 33 is opposite to the side block 32 again, and the mutual attraction force between the first electromagnet 61 and the second electromagnet 62 is generated again, so that the bottom of the insertion rod 29 is maintained in the insertion hole 28.

[0139] In the embodiment, before the inner plate 20 enters the closed area, the communication rod 54 extends into the second inner cavity 31, so that the first inner block 33 is opposite to the side block 32 through the second inner block 56 and the pull rope 58, after the inner plate 20 enters the closed area, the inner plate 20 continuously applies an external force to the insertion rod 29, and in the process that the inner plate 20 makes the inner rod 10 gradually extend out of the first through hole 11, the insertion rod 29 gradually extends out of the insertion hole 28. During the process that the inner rod 10 returns to the original position, the communication rod 54 will gradually enter the second inner cavity 31, so as to gradually make the insertion rod 29 return to the original position.
