[0030] Please refer to Figures 1 - 3 , in the embodiment of the present utility model, a smoke collection mechanism for a tilting melting furnace includes a support base 1. A melting furnace 2 for melting metal is rotatably connected inside the support base 1. The top end of the support base 1 is connected with a collection hood 3 for collecting harmful gases through a fixed rod 401. It is characterized in that a limiting mechanism 4 is provided on the support base 1 and the collection hood 3;

[0031] The limiting mechanism 4 includes a transmission unit and a reset unit;

[0032] The transmission unit is used to release the limit between the support base 1 and the collection hood 3;

[0033] The reset unit is used to provide a reset elastic force for the movement of the transmission unit;

[0034] The transmission unit includes a fixed rod 401, a pressing rod 402, a movable rod 403, an abutting block 404, a movable block 405, and a limit block 406;

[0035] The fixed rod 401 is fixed at the bottom end of the collection hood 3 and extends to the inside of the top end of the support base 1. The fixed rod 401 is used to provide support for the collection hood 3;

[0036] The pressing rod 402 is vertically slidably installed on the inner wall of the fixed rod 401 and extends to the outside of the fixed rod 401. The pressing rod 402 is used to drive the movable rod 403 to move synchronously;

[0037] The movable rod 403 is fixed at the bottom end of the pressing rod 402 and extends to the inside of the fixed rod 401. The movable rod 403 is used to push the abutting block 404 to move;

[0038] The abutting block 404 is fixed at the bottom end of the movable rod 403. The abutting block 404 is used to give a moving thrust to the movable block 405;

[0039] The movable block 405 is axially slidably installed on the inner wall of the fixed rod 401, and the movable block 405 is used to drive the limiting block 406 to move synchronously;

[0040] The limiting block 406 is fixed to the bottom end of the movable block 405 and extends outside the fixed rod 401 and into the inside of the support base 1. The limiting block 406 is used to provide a limit for the connection between the fixed rod 401 and the collection cover 3;

[0041] The reset unit includes a positioning rod 407 and a spring 408;

[0042] The positioning rod 407 is fixed to the inner wall of the fixed rod 401 and passes through the protruding part of the outer wall of the movable block 405. The positioning rod 407 is used to guide the movement of the movable block 405;

[0043] The two ends of the spring 408 are respectively clamped on the inner wall of the fixed rod 401 and the outside of the protruding part of the movable block 405. The spring 408 is used to provide a reciprocating elastic force for the moving movable block 405.

[0044] In this embodiment: when using this device, the collection cover 3 is started to collect the toxic gas produced by the smelting of the support base 1. When the collection cover 3 needs to be cleaned, a downward pressure can be applied to the pressing rod 402. The pressing rod 402 moves vertically along the inner wall of the fixed rod 401 under force. The vertically moving pressing rod 402 will synchronously apply a downward pressure to the movable rod 403. The movable rod 403 that moves under force will synchronously drive the abutting block 404 to move, so that the inclined end face of the abutting block 404 gives an extrusion force to the inclined end face of the movable block 405, thereby pushing the movable block 405 to move axially. The axially moving movable block 405 synchronously drives the limiting block 406 to move axially, so that the limiting block 406 moves from the limiting groove at the top end of the support base 1 to the docking groove at the top end of the support base 1, that is, directly below the fixed rod 401. At this time, an upward pulling force can be applied to the collection cover 3 to separate the collection cover 3 and the support base 1, achieving the purpose of quickly cleaning the collection cover 3 and further improving the work efficiency.

[0045] Please refer specifically to Figures 1 - 3 , a docking groove for inserting the fixed rod 401 is formed inside the top end of the support base 1, a limiting groove for the limiting block 406 to enter is formed in the docking groove, the bottom ends of the abutting block 404 and the movable block 405 are both inclined, and the inclination angles are the same. A sliding groove for the axial movement of the abutting block 404 and the movable block 405 is formed on the inner wall of the fixed rod 401, a sliding groove for the vertical movement of the pressing rod 402 is formed on the inner wall of the fixed rod 401, and the number of movable rods 403 is set to two. The two movable rods 403 are symmetrically distributed inside the two fixed rods 401.

[0046] In this embodiment: Through this structure, during the process of the pressing rod 402 moving downward, extrusion force can be synchronously applied to the two symmetrically arranged movable rods 403 and the abutting blocks 404, thereby synchronously driving the limiting blocks 406 to move, so that the two limiting blocks 406 are synchronously moved out of the internal limiting groove of the support base 1, and the limitation on the support base 1 and the collection cover 3 is released.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
