7. The use method of the integrated corn harvesting device as claimed in claim 5, characterized by comprising the following steps:
s1: corn ears are conveyed into a shell (1) through a feeding pipe (2), a fixed motor (32) is operated to drive a first worm (33) to be matched with a first worm wheel (34), a second worm wheel (35) and a third worm wheel (36) in a rotating mode, so that four driving bevel gears (37) rotate simultaneously, and the rotating directions of two adjacent driving bevel gears (37) are opposite;
s2: the corn ears conveyed into the shell (1) transversely fall among the four hollow pipes (41), the four hollow pipes (41) rotate to be matched with the positive spiral blades (44) on the side surfaces of the four hollow pipes, so that the corn ears are conveyed leftwards among the four hollow pipes (41) in a transverse state, the coatings on the corn ears are cut off by the positive spiral blades (44) due to the fact that the transmission ratio between the first worm wheel (34) and the first worm (33) is different from the transmission ratio between the second worm wheel (35) and the third worm wheel (36) and the first worm (33), and the coatings on the corn ears are rapidly moved leftwards due to the fact that the rotation directions of the positive spiral blades (44) on the two adjacent hollow pipes (41) are opposite, and then the coatings on the corn ears entering the shell (1) are removed secondarily by the negative spiral blades (45) after the corn ears are moved leftwards to the negative spiral blades (45);
s3: after the coat on the corn ear is cut off, the corn ear continuously moves leftwards, when the corn ear is positioned between the guide rods (46), because the corn ear is conical, one end of the corn ear which is a conical head can downwards clamp between the guide rods (46), when the corn ear continuously moves leftwards along with the corn ear, after the distance between the guide rods (46) is larger than the diameter of the corn ear, the corn ear can move towards the inside of the upper rotary drum (56) corresponding to the diameter of the corn ear along a channel formed by the L-shaped plate (52) and the guide plate (53), the corn ear can be firstly clamped between the arc-shaped rods (515) inside the upper rotary drum (56), the rotating motor (512) is operated to drive the second worm (513) to rotate, so that the transmission worm wheel (55) drives the corn ear in the upper rotary drum (56) to clockwise rotate, and simultaneously the transmission worm wheel (55) is matched with the inner gear (510) inside to drive the crushing roller (511) on the driven gear (59) to clockwise rotate so as to thresh the corn ear on the corn ear, and the corn ear, under the action of gravity, the corn ear downwards moves slowly, and when the corn ear drops to pass through the inner gear (7) and is threshed on the inner wall of the isolation net (7) and drops to the corn ear to the right, the corn ear screen, and the corn ear screen (7) to thresh the corn ear.
