A guide A7 is provided on the frame 1 above the carrying plate B10 on the other side of the conveying chain 3. The guide a7 is provided to face the cutting blade 6.

The guide A7 is composed of a guide arc rod 21 and a guide cross rod 22; two groups of guide arc rods 21 are arranged above the bearing plate B10 at intervals (see the attached figure 8 in the specification); one end of the guide arc rod 21 is hinged with a guide cross rod 22 (see the description attached figures 5 and 8); the guide arc rod 21 and the guide cross rod 22 are connected with the frame 1 on one side through a compression spring 26 (see the description and the attached figure 5).

The guide a7 is thus provided for the purpose of: so that during operation, the conveying chain 3 drives the scaly fish to pass through between the guider A7 and the sectioning knife 6 through the fishhook 4, the guide arc rod 21 can extrude the scaly fish from the side surface under the action of the elastic force of the extrusion spring 26, and the scaly fish rotates towards the sectioning knife 6 around the fishhook 4, so that the fish belly of the scaly fish is forced to keep a certain pressure contact with the sectioning knife 6, and further the smooth operation of sectioning is ensured.

The purpose of arranging the guide cross bar 22 at one side of the guide arc bar 21 is as follows: so that in the course of the work, the fish with scales keeps the back in contact with dissecting sword 6 under the direction of guide arc pole 21, when the fish with scales contacts with guide horizontal pole 22, guide horizontal pole 22 forces the fish maw of fish with scales to continue dissecting sword 6 and keep certain pressure contact, has avoided the fish with scales to take place to dissect the problem that can not dissect smoothly with dissecting sword 6 separation.

The two groups of guide arc rods 21 above the bearing plate B10 are arranged at intervals for the purpose of: so that during operation, two sets of guide arc rods 21 can guide the scaled fish to move forward in a clamping state at the back of the fish, and the purpose of stably running the scaled fish under the guide of the two sets of guide arc rods 21 is achieved.

One side of the guide A7 is provided with a guide B8; the guide B8 is disposed opposite to the organ to be removed (see fig. 2 in the specification). The guide B8 is composed of a front arc guide 23, a rear arc guide 24, and an arc guide 25 (see fig. 6 in the specification).

Two groups of arched guide rods 25 are arranged above the bearing plate B10 at intervals (see the description and the attached figure 9); one end of the arched guide rod 25 is hinged with a front arched guide rod 23; the other end of the arched guide rod 25 is hinged with a rear arched guide rod 24; the front arc guide rod 23, the arc guide rod 25 and the rear arc guide rod 24 form a bent arc structure.

The front arc guide rod 23, the arc guide rod 25 and the rear arc guide rod 24 are all connected with the frame 1 on one side through a compression spring 26 (see the attached figures 6 and 9 in the specification).

Due to the characteristic of arc-shaped structure of the fish cavity with the scaly fish, after the guide B8 is arranged, when the conveying chain 3 drives the scaly fish to pass through the guide B8 and the viscera through the fishhook 4; the front arc-shaped guide rod 23 firstly presses the scaly fish from the side under the action of the elastic force of the pressing spring 26, so that the scaly fish rotates around the fishhook 4 towards the cutting knife 6, and the rotated viscera removing part is forced to enter the fish belly to clean the viscera; then the arched guide rod 25 can further extrude the scaly fish from the side surface, so that when the viscera in the middle of the fish maw are cleaned by removing the viscera, the scaly fish can further rotate around the fishhook 4 under the compression of the arched guide rod 25, and the viscera can further enter the middle of the fish maw to clean the viscera; when the scaly fish contacts the rear arc-shaped guide rod 24, the scaly fish rotates towards the rear arc-shaped guide rod 24 under the action of the viscera-removing pressure and keeps sliding contact with the rear arc-shaped guide rod. Thus, the scaled fish can adaptively rotate around the fishhook 4 under the guidance of the front arc-shaped guide rod 23, the arc-shaped guide rod 25 and the rear arc-shaped guide rod 24, so that viscera can be removed by a certain pressure along the bottom of the fish belly; the problem that when the scaly fish passes through the visceral organ removing side in a straight line track, the visceral organs cannot contact the middle position of the fish maw to cause incomplete cleaning and the problem that the visceral organs damage the fish body due to overlarge pressure at the two ends of the fish maw are solved.

When the scaly fish processing device works, firstly, the scaly fish is processed into dead fish by knocking or other methods, and then the scaly fish is sequentially hung on the fishhook 4 through the fisheye position. The rotating conveyor chain 3 will now bring the scaly fish by means of the hooks 4 backwards along the carrier plate a 9.

When the conveyor chain 3 drives the scaly fish to pass through the descaling units through the fishhooks 4, the rotating descaling rolls 13 brush the scales on the surfaces of the scaly fish through the descaling steel brushes on the surfaces in a squeezing brushing mode, so that the purpose of descaling is achieved.

When the conveying chain 3 drives the scaly fishes to pass through the descaling unit through the fishhooks 4 and then moves backwards along the bearing plate B10, the guide arc rods 21 in the guide device A7 can extrude the scaly fishes from the side under the action of the elastic force of the extrusion spring 26, so that the scaly fishes rotate around the fishhooks 4 towards the sectioning knife 6, and then the fish bellies of the scaly fishes can be always in certain pressure contact with the sectioning knife 6 under the guide of the guide cross rods 22, and the purpose of enabling the rotating sectioning knife 6 to complete fish belly sectioning work is achieved.

When the conveying chain 3 drives the scaly fish to pass through the dissecting knife 6 through the fishhook 4, the scaly fish passes through the guide B8 and the viscera of the fish; the front arc-shaped guide rod 23 firstly presses the scaly fish from the side under the action of the elastic force of the pressing spring 26, so that the scaly fish rotates around the fishhook 4 towards the cutting knife 6, and the rotated viscera removing part enters the fish belly from the cutting part to clean the viscera (see the attached figure 10 of the specification); then the arched guide rod 25 further presses the scaly fish from the side surface, so that when the viscera in the middle of the fish maw are cleaned by removing the viscera, the scaly fish further rotates around the fishhook 4 under the compression of the arched guide rod 25, and the viscera can further enter the middle of the fish maw to clean the viscera (see the attached figure 11 in the specification); when the scaly fish contacts the rear arc-shaped guide rod 24, the scaly fish rotates towards the rear arc-shaped guide rod 24 under the action of the viscera-removing pressure and keeps sliding contact with the rear arc-shaped guide rod (see the attached figure 11 in the specification). Therefore, the scaly fish can adaptively rotate around the fishhook 4 under the guidance of the front arc-shaped guide rod 23, the arc-shaped guide rod 25 and the rear arc-shaped guide rod 24, so that viscera can be cleaned along the bottom of the fish belly by removing viscera with certain pressure all the time.

When the conveyor chain 3 drives the scaled fish to pass through the viscera through the fishhooks 4 and run to the tail end of the bearing plate B10, the fishhooks 4 rotate downwards along with the conveyor chain 3 to be separated from the scaled fish, and then the scaled fish slides down into the snakeheads 2 under the action of inertia. The scaly fish processing device can completely complete the 'descaling', 'sectioning' and 'dirty-removing' work of the scaly fish.

As an improvement of the present invention, the scaly fish processing apparatus may be provided in a cabinet, and a cleaning nozzle may be provided in the cabinet so that the cleaning nozzle can clean the descaler 5 and the viscera by the sprayed cleaning water during operation.

The scaly fish processing device is compact in structure and ingenious in design, and can control the advancing posture of the scaly fish under the action of the guide A7 and the guide B8 during working; the sectioning knife 6 can exactly carve the fish maw without damaging the viscera; the viscera removing device can perform 'profile modeling' cleaning along the inside of the fish belly, solves the problems of incomplete viscera removing and easy fish body damage existing in the existing scaly fish processing device, and is particularly suitable for the use requirements of fish processing enterprises.
