The invention provides a picking device convenient for residue film cleaning and winding. The picking device comprises a machine frame, nail teeth and a picking notch, wherein a connecting pin is vertically welded at the middle part of the front end surface of the machine frame; soil breaking teeth are arranged at the two corner positions of the bottom surface of the front end of the machine frame; the two soil breaking teeth are in forward parallel arrangement. Through the arrangement of a film collecting box and a wolf tooth roller, film cleaning grooves are formed in the back end side wallof the film collecting box, and the interval between the film cleaning grooves is identical to the intervals between film conveying teeth arranged on the wolf tooth roller, so that when the film conveying teeth arranged on the wolf tooth roller pass through the film cleaning groove, residue films on the film conveying teeth can be scratched into the film collecting box through the side wall of thefilm cleaning groove; the goal of collecting the residue film can be achieved; in addition, the upper end of the film conveying teeth arranged on the wolf tooth roller is of a cuboid structure, the end of the film conveying teeth is of a frustum structure, so that a notch is formed in each film conveying tooth; the film conveying teeth have the stronger film hanging capability; through the use ina way of being matched with the film collecting box, the effect of collecting the residue film can be achieved.
