The invention discloses aquatic plant cutting and compressing equipment, and relates to the technical field of aquatic plant cleaning. The aquatic plant cutting and compressing equipment comprises a rack, wherein a conveying groove is formed in the middle of the rack, an arc-shaped cover is fixedly connected to one end of the conveying groove, a declination groove is formed in the end, away from the arc-shaped cover, of the rack, a collecting hopper is fixedly connected to the end, away from the conveying groove, of the declination groove, first chain wheels are arranged in the two sides of the end, close to the arc-shaped cover, of the conveying groove correspondingly, driving shafts are fixedly installed in the two first chain wheels, and the two ends of the driving shafts penetrate through the two sides of the rack. According to the aquatic plant cutting and compressing equipment, the first chain wheels are driven to continuously rotate, a function of cutting aquatic plants is achieved, furthermore, a function of continuously shifting and conveying the aquatic plants through a telescopic shifting rod is achieved, meanwhile, the aquatic plants enter a fixed cylinder and a rotating cylinder through an extrusion disc to drive the rotating cylinder to continuously rotate, and therefore, functions of extruding and spin-drying the aquatic plants are achieved and the aquatic plants can be conveniently transported and processed in the later period.
