Working principle:
the first working state: the power of the power rotating shaft 1 is matched with the passive friction ring 12 through the active friction wheel 11, the power is provided to drive the open centrifugal impeller 4 to rotate, the threshold value of the tensile force applied to the open centrifugal impeller 4 is obtained according to a plurality of tests, the damage of the conveyed mulching film is less in the range of the threshold value, the method for adjusting the open centrifugal impeller 4 to meet the threshold value is that the friction force between the active friction wheel 11 and the passive friction ring 12 is adjusted, when the tensile force applied to the open centrifugal impeller 4 is larger than the threshold value, the active friction wheel 11 and the passive friction ring 12 can slip, the power cannot be conveyed, and the second working state is entered at the moment.
And a second working state: when the power rotating shaft 1 still transmits power, the open centrifugal impeller 4 cannot rotate, at this moment, originally, because the rotating speed of the open centrifugal impeller 4 is greater than that of the fixed ring 14, the first bump 16 of the movable ring 13 can only circularly slide along the second arc-shaped guide rail 19 on the end surface of the fixed ring 14 to low and high, the phenomenon that the fixed ring 14 and the movable ring 13 do not form a fit is broken, at this moment, the movable ring 13 stops rotating, and under the pushing of the spring 15, the movable ring 13 slides towards the fixed ring 14, because the clamping block 20 can slide back and forth in the bayonet 22, but cannot separate from the bayonet 22, that is, the movable ring 13 and the open centrifugal impeller 4 always keep a transmission relation, after the open centrifugal impeller 4 stops rotating, the movable ring 13 is matched with the fixed ring 14, the first bump 16 and the second bump 18 are in an interference fit, at this moment, the power transmitted by the fixed ring 14 can completely grind the part of the fixed ring 4, which affects the transmission, and the possibility of the device is avoided, and the process is very short, after the accident affecting the rotation of the open centrifugal impeller 4 is completed, the third working state is entered.
Third working state: because the external tension is reduced below the threshold value, the transmission relation between the driving friction wheel 11 and the driven friction ring 12 is restored, the rotation speed of the open centrifugal impeller 4 is changed back to a state greater than the speed of the fixed ring 14, at the moment, the first projection 16 can circularly slide along the second arc-shaped guide rail 19 to the lower side, at the moment, the clamping block 20 can further slide into the bayonet 22, the spring 15 is compressed, the power of the open centrifugal impeller 4 is still provided by the driving friction wheel 11 and the driven friction ring 12, and the working relation is restored to the first working state.
