The invention discloses a melon and fruit cutting device. The melon and fruit cutting device comprises a cutting table, a hydraulic press is fixed to one end of the cutting table through a machine frame bolt, and a piston rod of the hydraulic press extends into the cutting table. A material push plate sleeves the free end of the piston rod of the hydraulic press through a connecting sleeve, two sets of mounting plates are symmetrically welded to the position, located at the other end of a dynamic press plate, of the outer wall of the cutting table, and two mounting plates are arranged in eachset of mounting plates. U-shaped supports are fixed to the two sets of mounting plates through bolts, and a transverse frame is welded between the two U-shaped supports. Sliding grooves are formed inthe upper surface of the transverse frame and the upper surface, located under the transverse frame, of the cutting table, mounting sliding frames are connected in the two sliding grooves in a clamping mode, and a cutter is connected between the two mounting sliding grooved in an inserting mode. The melon and fruit cutting device is suitable for cutting melon and fruit products in food processing,can be applied to different kinds of melon and fruit cutting, and can meet different cutting needs.
