[0002] Loach and eel are small fish, and their meat is delicate and nutritious, which is loved by consumers. Before cooking, loach and eel usually need to be slaughtered and deboned. The existing slaughtering and deboning method is mainly manual, which can meet the needs of daily life of residents. However, in aquatic product deep processing enterprises and large-scale hotels and other enterprises, the work efficiency of manual slaughtering and deboning cannot meet the requirements. In order to solve this problem, the patent document with application number 201910162532.8 and the name of loach and loach bone removing and slaughtering machine solves the problem of low efficiency of manual loach and loach slaughtering. The loach and loach to be slaughtered are poured into the feeding box and then enter the slaughtering conveying plate through the discharge pipe. In this process, the conveying tooth disc grabs the loach or loach and pushes it forward, and the slaughtering and deboning of loach and loach are completed by rotating the bone removing cutter, thereby solving the problem of low work efficiency of existing loach and loach manual slaughtering and deboning.

[0003] Although the slaughtering machine solves the problem of low work efficiency of existing loach and loach manual slaughtering and deboning, the loach and loach bone removing and slaughtering machine has a high meat content in the removed fish bones during the process of loach and loach belly cutting and bone removing, because the bone removing cutter is installed in parallel. On the other hand, the existing slaughtering machine relies on symmetrical rollers as power wheels to push the fish body forward during loach and loach slaughtering. However, due to the body structure of loach and loach, the slaughtering knife (slaughtering opening) is prone to deviation. Once the deviation occurs, it is difficult to complete the bone removing operation, so it is necessary to improve it. SUMMARY

[0004] The purpose of the present application is to provide a loach and eel precise cutting and bone removing machine which can prevent the slaughtering knife from deviating during slaughtering, effectively improve the bone removing accuracy, and reduce the meat content of fish bones.

Specific embodiments

[0030] As shown in the attached Figures 1-13 figure

[0031] This precise eel and loach剖切 and boning machine consists of a frame 1, a feed pipe 2, a discharge pipe ३, a belly-cutting mechanism, a conveying mechanism, a fish protection component, a boning mechanism and a compaction mechanism. The frame 1 is a rectangular frame, and a first fixed bracket 4 is fixedly installed on the inner bottom surface of the frame 1. The cross-section of the first fixed bracket 4 is in the shape of "冂", and a second fixed bracket 5 is fixedly installed on the inner bottom surface of the frame 1 on one side of the first fixed bracket 4. The second fixed bracket 5 is in a frame shape.

[0032] The first fixed support 4 is fixedly installed with the feeding pipe 2 at one end of the rack 1. The feeding pipe 2 is in a circular tube shape. The first fixed support 4 at one side below the feeding pipe 2 is provided with a belly-splitting mechanism. The belly-splitting mechanism comprises a cutting motor 6, a cutting shaft 7 and a cutting cutter 8. The cutting motor 6 is fixedly installed on the inner bottom surface of the rack 1 below the first fixed support 4 through a motor mounting frame. The first fixed support 4 at one side of the cutting motor 6 is fixedly installed with an assembly block 9. The cutting shaft 7 is movably installed on the assembly block 9 through a bearing. The cutting cutter 8 is fixedly installed at one end of the cutting shaft 7. A driven pulley 10 is fixedly installed at the other end of the cutting shaft 7. A driving pulley 11 is fixedly installed on the transmission shaft of the cutting motor 6. The driving pulley 11 and the driven pulley 10 are connected through a transmission belt 12. In use, the transmission shaft of the cutting motor 6 drives the cutting shaft 7 and the cutting cutter 8 to rotate through the cooperation between the driving pulley 11, the driven pulley 10 and the transmission belt 12.

[0033] The first fixed support 4 corresponding to the cutting cutter 8 is provided with a knife slot 13. The purpose of such arrangement is to facilitate the extension of one end of the cutting cutter 8 above the first fixed support 4, and to further facilitate the subsequent cutting operation of the cutting cutter 8.

[0034] The other end of the rack 1 is provided with a discharging pipe 3 corresponding to the feeding pipe 2 through a second fixed support 5. The discharging pipe 3 is in a rectangular tube shape. The discharging pipe 3 is symmetrically provided with connecting wings 14 at one end. The purpose of such arrangement is to guide the eel and loach after bone removal. The connecting wings 14 are provided with an upper baffle 15. The upper baffle 15 is fixedly connected with the discharging pipe 3 through a straight plate 16. The purpose of such arrangement is that the upper baffle 15 shields above the fish guard 31 to prevent the eel and loach from running out of the fish guard 31 during the bone removal process.

[0035] The inner side of the discharging pipe 3 is provided with a discharging slope 17. The purpose of such arrangement is to facilitate the eel and loach after bone removal to slide out of the discharging slope 17 of the discharging pipe 3 under the action of their own gravity.

[0036] The first fixed support 4 above the belly-splitting mechanism is provided with a conveying mechanism through a synchronous opening and closing member. The synchronous opening and closing member comprises vertical plates 18, slide rods 19, connecting frames 20, bearing seats 21, a first rack 22 and a second rack 23. The vertical plates 18 are fixedly installed on the rack 1 at intervals. Two slide rods 19 are symmetrically arranged between the vertical plates 18. Two slide blocks 24 are movably installed on each slide rod 19 at intervals. A slide plate 25 is fixedly installed on the two slide blocks 24 on the same side. The connecting frames 20 are arranged on the first fixed support 4 between the slide plates 25. Limiting nails 26 are fixedly installed on the connecting frames 20 corresponding to the slide plates 25 on both sides. The purpose of such arrangement is to limit the distance between the two slide plates 25 through the limiting nails 26 to prevent the two slide plates 25 from being excessively close to each other, which affects the feeding of the eel and loach in the later stage.

[0037] The connecting frame 20 is fixedly provided with a bearing seat 21, which is a detachable structure with two layers. The bearing seat 21 is provided with an assembly groove. A gear is movably arranged in the assembly groove through a gear shaft and a bearing. The first and second racks 22 and 23 are movably arranged on the assembly grooves on the two sides of the gear, respectively. The first and second racks 22 and 23 are connected with the gear in meshing mode, respectively. The first and second racks 22 and 23 extend to the outside of the bearing seat 21, respectively. The first rack 22 is fixedly connected with the left slide plate 25. The second rack 23 is fixedly connected with the right slide plate 25. In use, the first and second racks 22 and 23 and the gear are matched to make the two slide plates 25 keep synchronous opening and closing movement.

[0038] The slide plates 25 are respectively provided with limiting plates 27. The third adjusting spring 28 is arranged between the limiting plates 27. In use, the two slide plates 25 have a mutual approach movement trend through the tension of the third adjusting spring 28.

[0039] The conveying mechanism includes a conveying motor 29 and conveying gears 30. The conveying motor 29 is fixedly arranged on the slide plates 25 of the synchronous opening and closing member. The conveying gears 30 are fixedly arranged on the transmission shaft of the conveying motor 29, respectively. In use, when the two slide plates 25 keep synchronous opening and closing movement, the conveying gears 30 keep synchronous opening and closing movement due to the fact that the conveying motor 29 is fixedly arranged on the slide plates 25 of the synchronous opening and closing member. Thus, when the two conveying gears 30 push the eels or loaches forward after the eels or loaches of different sizes enter between the two conveying gears 30, the eels or loaches always keep centered between the two conveying gears 30.

[0040] The gap between the conveying gears 30 corresponds to the cutting knife disc 8. The purpose of such arrangement is to facilitate the cutting knife disc 8 to perform the belly cutting operation at the same time when the conveying gears 30 convey the eels or loaches.

[0041] The fish protection assembly is arranged between the conveying mechanism and the discharge pipe 3. The fish protection assembly includes fish protection plates 31, connecting rods 32, connecting plates 33 and first adjusting springs 34. The two fish protection plates 31 are arranged at intervals. One end of each fish protection plate 31 is fixedly connected with the slide plates 25 of the synchronous opening and closing member through the connecting rod 32. The fish protection plate 31 is provided with an assembly hole 35 for facilitating the installation of the connecting rod 32. The other end of each fish protection plate 31 is fixedly provided with the connecting plate 33. The first adjusting spring 34 is arranged between the connecting plates 33. In use, the two connecting plates 33 have a mutual approach movement trend through the tension of the first adjusting spring 34.

[0042] The connecting plate 33 is fixedly provided with a roller shaft 36, and the roller shaft 36 is movably provided with a sliding roller 37. A guide plate 69 is arranged on the corresponding second fixed support 5 of the sliding roller 37. A positioning sliding groove 38 is arranged on the guide plate 69 at a position corresponding to the sliding roller 37. The positioning sliding groove 38 is in the shape of a long circular hole. The sliding roller 37 is in sliding connection with the positioning sliding groove 38. In use, the sliding roller 37 and the positioning sliding groove 38 are matched to guide and limit the connecting plate 33 and the fish guard plate 31, thereby further preventing the gap between the two fish guard plates 31 from being excessively widened or excessively contracted.

[0043] The fish guard plate 31 is in the shape of a long rectangular body. An arc-shaped accommodation groove 39 is arranged on the inner side of the fish guard plate 31. The arc-shaped accommodation groove 39 is arranged to accommodate the conveying gear 30, thereby facilitating the contact connection between the conveying gear 30 and the eel or loach.

[0044] An inlet inclined surface 40 is arranged on the fish guard plate 31 in front of the arc-shaped accommodation groove 39. The inlet inclined surface 40 is arranged to facilitate the guidance of the eel or loach into the space between the two fish guard plates 31.

[0045] A stabilizing inclined surface 41 is arranged on the fish guard plate 31 below the arc-shaped accommodation groove 39. The stabilizing inclined surface 41 is matched with the anti-skid block 57 to keep the opening of the eel or loach belly cut open in a state of being kept open, thereby facilitating the subsequent bone removal operation of the bone removal cutter 63.

[0046] A gear accommodation groove 42 is arranged on the outer side of the fish guard plate 31. The gear accommodation groove 42 is arranged to accommodate the conveying gear 30, thereby enabling the conveying gear 30 to smoothly convey the eel or loach into the space between the two fish guard plates 31.

[0047] The second fixed support 5 above the fish guard assembly is provided with a compacting mechanism. The compacting mechanism comprises a support seat 43, a support rod 44, an assembly frame 45, a driving motor 46, a compression gear disc 47, and a second adjusting spring 48. Two support seats 43 are arranged at intervals. The support rod 44 is movably arranged between the support seats 43 through bearings. The assembly frame 45 is fixedly arranged on the support rod 44. A positioning pin 49 is arranged at one end of the assembly frame 45. The second adjusting spring 48 is arranged between the positioning pin 49 and the rack 1. In use, under the action of the pulling force of the second adjusting spring 48, the end of the assembly frame 45 connected with the second adjusting spring 48 and the rack 1 have a mutual approaching movement trend.

[0048] The assembly frame 45 on one side of the positioning pin 49 is fixedly installed with a driving motor 46 through a motor mounting seat, the other end of the assembly frame 45 away from the positioning pin 49 is movably installed with a pressing shaft 50 through a bearing, the pressing shaft 50 is fixedly installed with a pressing gear disc 47, the pressing gear disc 47 on one side of the pressing shaft 50 is fixedly installed with a transmission belt pulley A 52, the transmission shaft of the driving motor 46 is fixedly installed with a transmission belt pulley B 53, the transmission belt pulley A 52 and the transmission belt pulley B 53 are connected through a connecting belt 54, and in use, the transmission shaft of the driving motor 46 drives the pressing gear disc 47 to rotate through the transmission belt pulley A 52, the transmission belt pulley B 53 and the connecting belt 54.

[0049] The assembly frame 45 on one side is fixedly installed with an adjusting seat 55, the adjusting seat 55 is threadedly installed with an adjusting screw 56, the adjusting screw 56 is in contact with the second fixed support 5, and the purpose of such arrangement is that the adjusting screw 56 is used for limiting the assembly frame 45 and the pressing gear disc 47, the spacing between the adjusting seat 55 and the second fixed support 5 is adjusted by rotating the adjusting screw 56, the adjusting seat 55 is fixedly connected with the assembly frame 45, the assembly frame 45 is movably installed with the pressing gear disc 47 through the pressing shaft 50, so as to further control the spacing between the pressing gear disc 47 and the anti-skid block 57.

[0050] The anti-skid block 57 on the corresponding first fixed support 4 of the pressing gear disc 47 is fixedly installed, the anti-skid block 57 is in the shape of a wedge-shaped long strip, a plurality of adjusting holes 58 are arranged on one end surface of the anti-skid block 57, and a fixed hole 59 is arranged on the corresponding first fixed support 4 of the adjusting hole 58, and the purpose of such arrangement is to facilitate the adjustment of the installation distance of the anti-skid block 57 on the first fixed support 4, so as to control the spacing between the anti-skid block 57 and the pressing gear disc 47, so as to be suitable for eels or loaches of different sizes.

[0051] The anti-skid block 57 on both sides of the adjusting hole 58 is provided with a let-in inclined groove 60, the let-in inclined groove 60 is used for giving way to the bone removing cutter disc 63, and the bone removing operation is facilitated.

[0052] The other end of the anti-skid block 57 is in the shape of a wedge in longitudinal section and in the shape of a “U” in transverse section, and barbs 61 are uniformly arranged on the upper surface of the anti-skid block 57, and the purpose of such arrangement is that the barbs 61 can prevent the eels or loaches from slipping on the wedge-shaped anti-skid block 57 due to the influence of the frictional force when the pressing gear disc 47 is used to press and convey the eels or loaches, so as to prevent the pressing gear disc 47 from being unable to normally convey.

[0053] The rack 1 below the fish protection assembly is provided with a bone removing mechanism, which comprises a bone removing motor 62, a bone removing cutter 63, a fixed seat 64 and a supporting arm 65. The bone removing motor 62 is fixedly installed on the second fixed support 5. The fixed seat 64 is fixedly installed on the inner bottom surface of the rack 1 below the bone removing motor 62. The supporting arm 65 is fixedly installed on the fixed seat 64 in a slanting manner corresponding to the bone removing motor 62. The bone removing shaft 66 is movably installed on the supporting arm 65 through a bearing. The bone removing cutter 63 is detachably installed on the bone removing shaft 66. The two bone removing cutters 63 are arranged in a spread-tail shape. The included angle between the two bone removing cutters 63 corresponds to the anti-skid block 57. The edges of the two bone removing cutters 63 are higher than the anti-skid block 57. The purpose of such arrangement is to form a triangular area between the edges of the two bone removing cutters 63 and the anti-skid block 57, and to completely strip the spine of eel or loach from the fish meat under the cutting action of the bone removing cutter 63.

[0054] The included angle between the two bone removing cutters 63 can range from 60° to 90°. The purpose of such arrangement is that when the included angle of the bone removing cutter 63 is 90°, the two bone removing cutters 63 do not interfere with each other when they are detached, which facilitates the user to detach and replace the bone removing cutters 63 when they are damaged.

[0055] The transmission shaft of the bone removing motor 62 is connected with the bone removing shaft 66 through a universal joint 67. During use, the transmission shaft of the bone removing motor 62 drives the universal joint 67 to rotate, and the universal joint 67 drives the bone removing shaft 66 and the bone removing cutter 63 to rotate synchronously, thereby performing the bone removing operation.

[0056] The front end of the feeding pipe 2 of the eel and loach precise cutting and bone removing machine is provided with a guide hopper 68. The guide hopper 68 is detachably connected with the rack 1. The guide hopper 68 is fixedly connected with the rack 1 through bolts. The guide hopper 68 is in the shape of an inclined chute. Symmetrical guide blocks 51 are arranged in the guide hopper 68. The gap between the guide blocks 51 corresponds to the feeding pipe 2. During use, the eel or loach slides along one end of the guide hopper 68 to the other end under its own action. With the cooperation of the guide blocks 51, the eel or loach conveniently slides into the feeding pipe 2 from the gap between the guide blocks 51.

[0057] Taking eel as an example, the eel and loach precise cutting and bone removing machine can directly put the eel into the feeding pipe 2 during use, or the guide hopper 68 can be installed first, and then the eel is put into the guide hopper 68, and then into the feeding pipe 2 through the guide hopper 68.

[0058] When the eels enter the feeding pipe 2 and move to the conveying gears 30, the two conveying motors 29 are started at the same time, one of the conveying motors 29 drives the corresponding conveying gear 30 to rotate clockwise, and the other conveying motor 29 drives the corresponding conveying gear 30 to rotate counterclockwise. Under the cooperation of the two conveying gears 30, the eels are grabbed and pushed forward. During this process, the two conveying gears 30 are always kept synchronous moving outward or inward by the synchronous opening and closing member, so that the eels can always be kept centered between the two conveying gears 30.

[0059] The cutting motor 6 is started, and the cutting shaft 7 of the cutting motor 6 drives the cutting cutter 8 to rotate. During the process of pushing the eels centered between the two conveying gears 30, the cutting cutter 8 cuts the eel belly naturally. After the eel belly is cut open, the eels continue to move forward under the inertia of the conveying gears 30. When the head of the eel moves between the pressing gear plate 47 and the anti-skid block 57, the driving motor 46 is started. The driving motor 46 drives the pressing gear plate 47 to rotate through the transmission belt pulley A 52, the transmission belt pulley B 53 and the connecting belt 54.

[0060] Due to the tension of the second adjusting spring 48 on one end of the assembly frame 45, and under the cooperation of the supporting rod 44, the other end of the assembly frame 45 exerts a downward force on the pressing gear plate 47. After the pressing gear plate 47 contacts the eel, the downward force is transmitted to the eel, so that the pressing gear plate 47 and the anti-skid block 57 clamp the eel. The rotating pressing gear plate 47 gives the eel a forward pushing force under the action of friction. The anti-skid block 57 in the shape of a wedge forms a pre-expansion to the opened eel belly, and the reverse tooth of the anti-skid block 57 can effectively prevent the eel from retreating under the pressure of the pressing gear plate 47.

[0061] When the pressing gear plate 47 drives the eel to reach the position of the bone removing cutter 63, the bone removing motor 62 is started. The bone removing motor 62 drives the bone removing cutter 63 to rotate through the universal joint 67. Since the anti-skid block 57 in the shape of a wedge forms a pre-expansion to the opened eel belly, the edges of the two bone removing cutters 63 and the cross section between the anti-skid blocks 57 form a triangular area. When the eel moves along the axial direction of the anti-skid block 57, the bone removing cutter 63 peels the spine from the fish meat along the abdominal cavity of the eel. After the bone is removed, the eel slides out of the discharge pipe 3, that is, the whole eel belly cutting and bone removing operation is completed. The bone removing precision of the cutting and bone removing machine is high, and the meat content of the fish bone is effectively reduced.
