2. A method of operating a header for a harvester that is resistant to clogging by cutting knives, as set forth in claim 1, comprising the steps of:
s10: the electric push rod (68) is started, the electric push rod (68) pushes the transmission shaft (66) to move under the guiding and limiting action of the guiding and limiting sliding seat (67), and the transmission shaft (66) drives the transmission bevel gear (65) to move in the moving process until the driving bevel gear (64) and the driven bevel gear (69) are meshed with the transmission bevel gear (65);
s20: the driving motor (61) is started, the driving motor (61) drives the traction shaft lever (4) and the driving worm wheel (62) to rotate clockwise, the traction shaft lever (4) drives the transmission bracket (41) and the cutting knife (5) to rotate in the rotating process, the cutting knife (5) performs harvesting operation, and the driving worm wheel (62) is meshed with the transmission worm (63), so that the driving worm wheel (62) drives the transmission worm (63) and the driving bevel gear (64) to rotate in the rotating process;
s30: because the driving bevel gear (64) is meshed with the transmission bevel gear (65), and the driven bevel gear (69) is meshed with the transmission bevel gear (65), the driving bevel gear (64) drives the transmission bevel gear (65), the driven bevel gear (69), the driven shaft (610) and the driven gear (611) to rotate in the rotating process;
s40: because the driven gear (611) is meshed with the transverse moving rack (612), the driven gear (611) drives the transverse moving rack (612) to move under the guiding action of the positioning sliding seat (613), and the compression spring (614) and the telescopic guide column (615) are stretched due to the tensile force until the transverse moving rack (612) moves to the blocking rotating block (7);
s50: when the cutter (5) rotates to harvest, the rotating block (7) rotates along with the rotating first transmission frame (411), and when the rotating block (7) rotates to the position of the transverse moving rack (612), the rotating block (7) collides with the transverse moving rack (612), so that the cutter (5) receives impact force to shake off crops blocked on the cutter (5);
s60: after crops that block up on cutting knife (5) shake off, driving motor (61) anticlockwise rotates, make cutting knife (5) gyration, and make sideslip rack (612) rebound under the direction effect of location slide (613), no longer block rotating block (7) to sideslip rack (612), electric putter (68) promote transmission shaft (66) at the spacing effect of direction spacing slide (67) rebound of direction this moment, transmission shaft (66) drive transmission bevel gear (65) removal at the in-process that removes, until driving bevel gear (64) and driven bevel gear (69) all separate with transmission bevel gear (65), driving motor (61) drive traction shaft lever (4) and drive worm wheel (62) clockwise rotation this moment, make cutting knife (5) reap the operation, when cutting knife (5) are blockked up, repeat above operation.
