<p>An arch-breaking unit (100) comprising a connecting rod (110) actuated into a reciprocating movement by an actuating mechanism (112). The connecting rod (110) is connected along the axial direction to one or more connecting elements (120). The connecting elements (120) are pivotally connected to the connecting rod (110). Material-paddling arms (130) are connected to at least one cantilever end (121) of the connecting elements (120). The material-paddling arms (130) are arranged at an angle with the connecting rod (120). When the connecting rod (120) is moving in the axial direction, under the effect of an arching resistance, the cantilever ends (121) of the connecting elements (120) connected to the material-paddling arms (130) generate an angular displacement relative to where the connecting elements (120) and the connecting rod (110) are pivotally connected, thus regulating an arch-breaking resistance exerted on the material-paddling arms (130). The arch-breaking unit increases the freedom of movement of the material-paddling arms, reduces the rate of wear, and extends service life. Also disclosed is a material chamber (300) equipped with the arch-breaking unit (100).</p> |
