The application discloses an amphibious operation vehicle plate mud breaking device, and belongs to amphibious cleaning operation
mechanical equipment. The device is composed of a connecting support, a driving unit and a rotary
cutting roller, wherein the connecting support is used for connecting an amphibious operation vehicle body or a working arm; the driving unit comprises a mounting base, left and right side plates, a driving motor, a chain transmission mechanism and the like; a motor mounting plate is changed in position through an adjusting screw to tension the chain; a sealing plate is quickly wrapped around a spacer to form a sealed transmission space through buckles and hasp lock rings; the rotary
cutting roller is a left-right symmetrical regular polygon hollow structure, equal-distance
cutting blades with staggered bending directions at the ends are mounted on the rotary cutting roller, sealing rubber sheets are arranged at both ends of the rotary cutting roller, and an inner center
pipe is hermetically welded with a side sealing plate to form a sealed cavity. The application can forcibly pre-
cut and break the riverbed plate mud, so that the spiral
mud pump can be smoothly sucked and transported, and has the characteristics of lightweight structure, convenient maintenance, no cutting blind area and small rotary resistance.
