[0018] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] In the present invention, the motor 6 is connected to the external electric control system through a wire. The above equipment and connection methods are all prior art and will not be described in detail here.

[0020] According to the instruction manual Figure 1-3As shown, a pair of dust hoods 14 are initially in a separated state, each dust hood 14 is composed of a semi-cone and a semi-tube body located above the semi-cone, and a pair of dust hoods 14 can form a complete cone and tube body after being spliced. When the utility model is in use, the motor 6 arranged on the upper surface of the support platform 5 is started, and the output shaft of the motor 6 drives the connected threaded rod 7 to rotate, and the threaded rod 7 drives the threaded first transmission rod 9 to move in the direction of the motor 6 (a threaded hole that can cooperate with the threaded rod 7 is provided in the first transmission rod 9), and when the first transmission rod 9 moves, it drives multiple hinged second transmission rods 10 to move, and when the multiple second transmission rods 10 move, it drives multiple rotationally connected sliders 11 to move in the slide groove 5-1 in the direction of the threaded rod 7, and when the pair of sliders 11 located on the same side of the threaded rod 7 moves, it drives the connected support rod 13 to move, thereby causing the two support rods 13 to move toward each other, and the two support rods 13 drive a pair of dust hoods 14 to move toward each other, so that A pair of dust hoods 14 are spliced ​​and are located above the crystallizer 4; the induced draft device connected to the smoke exhaust pipe 18 is started, and the motor 6 lifting device clamps the motor 6 and the steel ingot through the pair of dust hoods 14 and extends into the crystallizer 4 for smelting. The smoke generated during smelting enters the bag dust collector 17 through the dust guide pipe 15 and the metal hose 16, and is discharged from the smoke exhaust pipe 18 after being filtered by the bag dust collector 17. After the smelting is completed, the motor 6 is reversed, thereby causing the pair of dust hoods 14 to move backwards to facilitate the transfer of the crystallizer 4. The utility model drives a pair of dust hoods 14 to move toward each other through the motor 6, and then splices them into a complete cone and column to the top of the crystallizer 4, cooperates with the bag dust collector 17 to remove dust from the smoke generated during smelting. When the smelting is completed, the motor 6 is reversed to cause the pair of dust hoods 14 to move backwards, thereby facilitating the transfer of the crystallizer 4. The operation of moving the dust hood 14 does not require manual work, which is safe for personnel and saves time and effort.

[0021] There is a possible implementation. When the slider 11 moves in the slide groove 5-1, it drives the limit block 12 to move in the limit groove 5-2. The limit groove 5-2 limits the limit block 12 to prevent the slider 11 from detaching from the slide groove 5-1, thereby ensuring that the support rod 13 set on each pair of sliders 11 is in a horizontal state.

[0022] In one possible implementation, one end of the threaded rod 7 away from the motor 6 is rotatably disposed on the shaft seat 8, and the shaft seat 8 supports and limits the end of the threaded rod 7 so that the threaded rod 7 is always in a horizontal state.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
