[0006] (2) When using the stirring device, it is difficult for the staff to prevent the material from being too heavy, causing the stirring rod to idle and affecting the service life of the drive structure. Utility Model Content

[0007] The technical problem solved by the utility model is to provide an aluminum alloy melting and casting furnace stirring device which is highly practical, can be simply operated and has a relatively simple structure. It solves the problem raised in the above background technology that when the stirring device is installed in the melting and casting furnace for use, the installation stability of the stirring device of the melting and casting furnace is poor, and it is not easy for the staff to install it quickly, resulting in inconvenience for the staff to use. When the staff uses the stirring device, it is difficult to prevent the material from being too heavy, resulting in idling of the stirring rod, which affects the service life of the driving structure.

[0008] To achieve the above purpose, the utility model is implemented through the following technical scheme: an aluminum alloy melting furnace stirring device, comprising an extension rod (1), characterized in that: both sides of the extension rod (1) are slidably connected to a shell (2), one side of the shell (2) is threadedly penetrated with a positioning bolt (3), one side of the extension rod (1) is equidistantly provided with threaded holes adapted to the positioning bolt (3), one side of the extension rod (1) is fixedly connected to a support rod (4), a driving motor (5) is fixedly installed in the middle of the top surface of the support rod (4), a transmission rod (6) is fixedly installed at the output end of the driving motor (5), an anti-idling component (7) is fixedly installed at the bottom of the transmission rod (6), one end of the shell (2) is fixedly connected to a connecting rod (8), and a quick installation component (9) is provided on the surface of the connecting rod (8);

[0009] The anti-idling component (7) comprises a tension sensor (71) fixedly mounted on one end of the transmission rod (6); the power supply of the tension sensor (71) is electrically connected to a controller (72) via a data line; and the controller (72) is located on one side of the top surface of the housing (2).

[0010] Optionally, a stirring rod is threadedly connected to the bottom of the tension sensor via a connecting plate, and flexible scrapers for scraping off foreign matter are fixedly mounted on both sides of the stirring rod.

[0013] Optionally, a through groove is formed on the top surface of the support rod, and the through groove is matched with the transmission rod.

[0014] The utility model provides a stirring device for an aluminum alloy melting and casting furnace, which has the following beneficial effects:

[0015] 1. The stirring device for the aluminum alloy melting and casting furnace is provided with an extension rod, a shell and a positioning bolt. When the staff needs to melt and cast the aluminum alloy, the material can be placed inside the designated melting and casting furnace. The staff can use the extension rod to expand the shell to a designated length according to the actual size of the melting and casting furnace, and screw the positioning bolt to fix the shell, thereby facilitating the staff to fix the stirring device to melting and casting furnaces of different sizes.
