the third motor control module can control the third motor (13) to rotate positively or reversely, the cutting knife (43) is driven to rotate to enable the knife head (45) to extend out of the knife holder by positive rotation, even if the cutting knife (43) enters a cutting state, the cutting knife (43) is driven to rotate to enable the knife head (45) to return to the knife holder by reverse rotation, even if the cutting knife (43) enters a furling state.
9. The control method of the blind ditch recycling device according to claim 8, characterized in that the control method comprises an automatic cutting mode, and the default initial state is as follows: the tensioning plate (33) is in a furled state, the cutting knife (43) is in a furled state, and the automatic cutting mode comprises the following steps:
s11, the control device controls the second motor control module to enable the second motor (11) to rotate forward, so that the two tightening plates (33) are in an open state, and the outer side walls of the two tightening plates (33) are attached to the pipe wall of the inner cavity of the blind ditch;
s12, the control device controls the third motor control module to enable the third motor (13) to rotate positively, so that the cutting knife (43) enters a cutting state;
and S13, the control device controls the first motor control module to operate and start cutting action until the wall of the blind ditch is completely cut off.
10. The control method of a blind ditch recycling device according to claim 9, characterized in that the control method further comprises a mode of returning to an initial state after the blind ditch recycling is completed, the mode comprises the following steps:
s21, the control device controls the second motor control module to enable the second motor (11) to rotate reversely, so that the two tensioning plates (33) return to the folded state from the unfolded state;
and S22, the control device controls the third motor control module to enable the third motor (13) to rotate reversely, so that the cutting knife (43) returns to the furled state from the cutting state.
