fifthly, the left side of the tractor (30) moves to the cleaning position, the tractor (30) stops, and the cleaning operation is carried out: as shown in the figures (2) and (4), the rotating motor (50) drives the sliding block (60), the cleaning fixing frame (61) and the cleaning brush (64) to move up and down through the power shaft (51), the driving wheel (52) and the transmission chain power part (53), and meanwhile, the water delivery pipe (65) sprays water to facilitate cleaning;
sixthly, after the cleaning operation is finished, stopping the sliding block (60), the cleaning fixing frame (61) and the cleaning brush (64) at the upper part of the door-shaped shell (20), and continuing to move the tractor (30) to the left until the upper surface of the left mechanical arm (33) contacts the lower surface of the hanger (12) of the first plate frame, wherein the left mechanical arm (33) is in an extrusion state;
seventhly, the tractor (30) continues to move left until the second plate frame contacts the first plate frame, at the moment, the input current of the driving motor of the tractor (30) reaches the limit, the driving motor of the tractor (30) reversely rotates through adjustment and starts to move left, and at the moment, the left mechanical arm (33) of the tractor (30) continues to be in a squeezing state;
eighthly, moving the tractor (30) to the right, contacting the upper surface of the left mechanical arm (33) with the lower surface of the hanger (12) of the second plate frame before the upper surface of the left mechanical arm (33) is separated from the constraint of the lower surface of the hanger (12) of the first plate frame, and continuously positioning the left mechanical arm (33) in a squeezing state;
ninthly, as shown in the figure (13), the tractor (30) continues to move to the right, the left mechanical arm (33) continues to be in a free state, and the second plate frame moves to the position;
and step ten, judging at the moment, if the cleaning is needed to be continued, opening the cleaning driving motor (22) again to enable the cleaning equipment to move rightwards for the distance of one plate frame, repeating the step two to the step nine, and if the cleaning is not needed to be continued, ending.
