[0028] Figures 1 to 5 Fig. shows an embodiment of the bridge-breaking device of the present utility model. The bridge-breaking device of this embodiment includes a stirring mechanism 1, a driving mechanism 2, a support frame 4, a silo 3 and a positioning platform 5. The silo 3 is arranged on the support frame 4, the stirring mechanism 1 is arranged on the silo 3, the stirring mechanism 1 is used for stirring the materials in the silo 3, the stirring mechanism 1 is detachably connected to the driving mechanism 2 through a connecting component 6, and the positioning platform 5 is used for positioning the support frame 4 to realize the corresponding connection between the stirring mechanism 1 and the driving mechanism 2.

[0029] When the bridge-breaking device discharges materials, a transfer mechanism (not shown in the figure) drives the support frame 4 and the silo 3 storing materials to move above the positioning platform 5, and then drives the silo 3 to descend until the support frame 4 is resisted and limited by the positioning platform 5, which means that the silo 3 has reached the corresponding connection height between the stirring mechanism 1 and the driving mechanism 2. At this time, the support frame 4 stops moving, and then the driving mechanism 2 and the stirring mechanism 1 are connected through the connecting component 6, and the driving mechanism 2 can drive the stirring mechanism 1 to stir the materials in the silo, avoiding material bridging and caking during discharging. Moreover, the stirring mechanism 1 and the driving mechanism 2 are detachably connected, which is convenient for the movement of the silo 3 to adapt to different feeding positions and has stronger flexibility.

When the first connecting member 61 and the second connecting member 62 need to be disconnected, the moving driving assembly 24 drives the rotating motor 23 to move in the reverse direction on the mounting frame 22 and retract into the mounting frame 22, avoiding obstruction to other structures, and the structure is compact.

[0034] Furthermore, as Figure 3 , Figure 4 and Figure 5 shown, in this embodiment, the second connecting member 62 includes a connecting shaft 621 and a plurality of axial clamping blocks 622.
