On the contrary, when the metal liquid in the furnace body 2 is poured and the furnace body 2 needs to be reset, the sliding sleeve 12 is positioned at the top of the sliding rod 11, the ratchet 41 can be outwards turned under the pushing action of the first ladder block 46 until the expansion ball head 44 is inserted into the positioning hole 45 and tightly supports the edge of the positioning hole 45, so that the ratchet 41 cannot be reset under the action of the first torsion spring 43, at the moment, the check groove 42 cannot apply one-way check force to the ratchet 41, so that the sliding sleeve 12 and the sliding rod 11 can freely slide, then the motor 32 is reversed to enable the worm 31 and the worm wheel 33 to be reversed together, the furnace body 2 can be reset, and the integral weight of the furnace body 2 can be reduced due to the fact that the inside of the furnace body 2 is in an emptying state in the process, and therefore, the furnace body 2 can be prevented from colliding with the frame 1 under the influence of gravity only through the support provided by the self-locking function between the worm 31 and the worm wheel 33.
After the furnace body 2 is completely reset, the sliding sleeve 12 and the sliding rod 11 can also restore to the original states, and at the moment, the ratchet 41 can overcome the expansion supporting force of the expansion ball head 44 to inwards turn under the pushing action of the second ladder block 47, so that the ratchet 41 is matched with the check groove 42 again to wait for the next turning operation of the furnace body 2.
In the process that the guide shaft 22 moves downwards along the arc-shaped sliding port 13, the guide shaft 22 can relatively move in the strip-shaped port 55, and along with the position change of the guide shaft 22, the guide shaft 22 can stir the connecting rod 54 to moderately rotate, then the rotating frame 51 is overturned under the transmission of the driving wheel 56 and the driven wheel 53, at the moment, the slag raking claw 52 can overturned along with the rotating frame 51 to rak slag collected at the furnace mouth of the furnace body 2, and when the gear 57 is meshed with the arc-shaped rack 58, the slag raking claw 52 can autorotate to pour slag. At the time of the subsequent return, the second torsion spring 59 can avoid the situation that the slag-off claw 52 fails to return accurately due to the centrifugal force inertia at the time of turning over.
Furthermore, it should be noted that, in the description of the present application, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present application can be understood by those skilled in the art according to the specific circumstances.
While the foregoing is directed to the preferred embodiments of the present application, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present application, and such modifications and adaptations are intended to be comprehended within the scope of the present application.
