The invention relates to dewatering extrusion equipment, in particular to dewatering extrusion equipment for straw pulp paper production. The technical problem to be solved by the invention is to provide the dewatering extrusion equipment for pressing straw pulp paper by a mechanical mean with uniform force for straw pulp paper production. The dewatering extrusion equipment for straw pulp paper production comprises a base, a guide rail, push plates, and the like, wherein the guide rail is installed on the top of the base. According to the equipment, a whole pulp can be extruded and dewatered by a pressing plate, so that the force of pulp pressing is the same, and the quality of straw pulp paper production is improved. The pressing plate is driven by a reduction motor to dewater and extrudethe straw pulp, and it is not necessary to pull a pressing rod to rotate downwards by hands all the time to extrude and dewater the pulp, so that the equipment can work better. In addition, a guide sleeve and apparatuses arranged on the guide sleeve can automatically move to the left, so that a rotation rod can move to the left, a distance of pressing down the pressing plate can become higher, and thereby an ever-increasing pulp thickness can be adapted.
