The invention relates to the field of agricultural squeezing and filtering, and provides novel plant waste residue squeezing and dewatering equipment which comprises a rack. A fixed disk is arranged on the rack and provided with an annular groove. An annular rotary table is arranged on the annular groove. A plurality of sets of feeding openings and discharging openings are evenly distributed in the rotary table. A plurality of sets of squeezing modules are evenly distributed between each set of feeding opening and discharging opening. An annular gear rack is annularly arranged outside the bottom of the rotary table, anti-skid grain is annularly arranged in the bottom of the rotary table, and the annular gear rack is connected with a clearance gear. An ejection mechanism is arranged at one side of the discharging openings. A traditional screw mechanical squeezing manner is changed, at least 30%-45% of water in waste residues is squeezed out and drained through the three-time opposite squeezing modules, and therefore the time and cost for material drying are greatly reduced. Meanwhile, a grinding disk type squeezing structure is adopted, automatic feeding, triple squeezing and discharging are achieved in the whole process, and the problem about dewatering of a large amount of matter waste in factories is greatly solved.
