A device for cutting fish heads as claimed in claim 1, wherein the belly opening mechanism (500) comprises a third ball screw slide (520), a fourth motor (510), a second swing disc (550) and a vibrating portion (560), the third ball screw slide (520) is mounted on the second swing disc (550), the vibrating portion (560) is mounted on the third ball screw slide (520), the fourth motor (510) is mounted on the third ball screw slide (520), and an output shaft of the fourth motor (510) is connected with the vibrating portion (560).

10. A method of processing a fish head in an apparatus for cutting fish heads according to any one of claims 1 to 9, the method comprising the steps of:

s1: after the fish is cleaned, the fish is input to the drain pan (320) through a conveying belt or manually, the furniture on the drain pan (320) fixes the fish to enable the fish to lie flat on the drain pan (320), one side of the fish body is attached to the outer wall of the fish head bucket (310), and the fish is driven by a second motor (323) at the bottom to rotate and process on the drain pan (320);

s2: when the belly opening mechanism (500) is rotated, a belly breaking knife (540) on the belly opening mechanism (500) can slide along the fish belly, so that the fish belly can be split from head to tail in a sliding mode, the vibrating portion (560) drives the belly breaking knife (540) to vibrate along the length direction of the knife when the fish belly is split in the sliding mode, the belly breaking effect is improved, and meanwhile a third ball screw slide rail (520) structure connected with the belly breaking knife (540) can swing along a second swing disc (550) to drive the vibrating belly breaking knife (540) to slide along an arc to split the fish belly;

s3: then the fish is rotated to a flushing mechanism (400), in the flushing mechanism (400), a flushing scraper (430) is driven by a first swinging disc (420) to slide along the arc direction, so as to drive the viscera in the dissected fish belly to be scraped out, meanwhile, in the scraping process, a water pump (450) connected with the flushing scraper (430) continuously inputs flushing water, and the flushed water and the viscera are converged into a water tank;

s4: then the fish head and the fish body are separated by downwards pressing the cutting mechanism (200) by utilizing the slice (230) which moves up and down, the fish head and the fish body are cut off through the slice (232), the fish head and the fish body are separated through the turning part (231), the joint of the fish head and the fish body can be turned over and separated along the plumb line of the turning part (231), the slice (230) is driven by the first motor (210) to deflect, the fish head and the fish body are extruded towards the outer wall of the fish head bucket (310) and the inner edge of the drain pan (320), and the fish head is ejected out through the turning plate (311) and input into the fish head bucket (310);

s5: the bottom of fish head fill (310) can be connected with fish head processing agency, and fish head processing agency can be equipped with the soaking pond, washes pond and pickling pond, and the soaking pond rinses out residual blood and the impurity of fish head, and the washing pond is used for washing residual mucus and attachment on the fish head surface, and pickling pond is pickled the fish head and is tasty and go the fishy smell, can pack the fish head part after fish head processing agency handles, directly makes the fresh sealed product, also can regard it as processing materials, produces cooked food etc. that the fish head derived.
