[0002] When smelting metal, metal powders of different compositions are placed in a furnace for melting and refining. During the refining process, the high-temperature powder and the melted metal liquid need to be stirred. Traditional stirring devices generally set the motor directly above the smelting furnace. During the stirring process, the high-temperature gas in the smelting furnace will rise, causing the working environment temperature of the motor to increase, thereby causing the motor to be damaged due to the high temperature.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN209893973U, patent name: A smelting furnace stirring device) is: the stirring device 2 includes a rotating motor 21 and a stirring shaft 22 arranged at the lower end of the rotating motor 21, and a blade 23 is arranged at the end of the stirring shaft 22. When in use, the stirring shaft 22 is driven to rotate by the rotating motor 21, thereby driving the blade 23 to rotate to achieve a stirring effect on the alloy liquid.

[0004] From the above implementation scheme, it can be seen that the lower end of the rotating motor is connected to the stirring shaft. When the motor is stirring the alloy liquid, the motor is above the alloy liquid. After the alloy powder melts, high temperature is generated, which will expose the motor to a high temperature environment. Such a working environment can easily damage the motor.

[0028] like Figures 1 to 6 As shown, a smelting furnace stirring device includes a motor 2, which is installed on the inner side of a motor case 1. The motor 2 is connected to a transmission connecting rod 3, and the transmission connecting rod 3 is connected to a stirring mechanism 4. The distance between the motor 2 and the stirring mechanism 4 is the length of the transmission connecting rod 3. Therefore, the motor 2 can be kept away from the top of the stirring mechanism 4, so that the high temperature of the stirring metal liquid will not affect the motor 2, thereby ensuring the normal service life of the motor 2 and also improving the safety of use.

[0029] A transmission housing 5 is provided on the outside of the transmission connecting rod 3, one end of the transmission housing 5 is mounted in the frame of the motor case 1, and a stirring linkage housing 6 is provided on the outside of the upper end of the stirring mechanism 4. The transmission housing 5 and the stirring linkage housing 6 are communicated with each other, so the transmission connecting rod 3 can be connected to the stirring mechanism 4 through the communication between the two. The transmission housing 5 and the stirring linkage housing 6 play a protective role for the transmission connecting rod 3 and the stirring mechanism 4 to prevent external forces from hitting the transmission connecting rod 3 and the stirring mechanism 4. In addition, lubricating oil can be added to the transmission housing 5 and the stirring linkage housing 6, so that the mechanical connection between the transmission connecting rod 3 and the stirring mechanism 4 can be lubricated, making the mechanism run more smoothly.

Therefore, the motor 2 can transfer the rotational kinetic energy to the first bevel gear 403 through the first universal joint 301, the extension rod body 302, and the second universal joint 303. The rotation of the first bevel gear 403 drives the second bevel gear 404 to rotate, and finally realizes the rotation of the stirring blade 407.

[0032] The transmission housing 5 includes a first cylinder 501, a second cylinder 502, and a third cylinder 503 which are connected in sequence.

The number and length of the cylinders constituting the transmission housing 5 can be set according to actual needs to match the length of the extension rod 302.

[0033] At least one seat bearing 505 is arranged inside the transmission housing 5 , and the extension rod 302 is connected to the seat bearing 505 . The seat bearing 505 supports the extension rod 302 inside the transmission housing 5 .

[0034] The second cylinder 502 is provided with a first oil filling hole 5021 for conveniently filling oil into the transmission housing 5 .

[0035] The stirring linkage shell 6 includes a stirring shell body 601, the upper end of the stirring shell body 601 is connected to the upper cover 602, and the lower end of the stirring shell body 601 is connected to the lower cover 603, the upper cover 602 and the lower cover 603 are both connected to the bearing 604, the stirring shell body 601 is provided with a second oil filling hole 6011, and the inside of the stirring linkage shell 6 can be filled with oil through the second oil filling hole 6011, and a docking port 6021 is provided on one side of the stirring shell body 601, and the docking port 6021 is connected to the transmission shell 5.
