Technical Field
[0001] This utility model relates to the field of crab rough processing technology, and in particular to a swimming crab processing device. Background Technology
[0002] Traditional rough processing of swimming crabs (such as removing legs, shells, gills, and cutting into pieces) relies heavily on manual labor or simple tools. Taking leg removal as an example, workers must use scissors or knives to cut the connection between the crab legs and the body one by one. Because swimming crab shells are hard and the leg joints are irregularly structured, even skilled workers find this time-consuming. More importantly, the force applied manually is inconsistent; some broken legs retain too much crab meat, resulting in waste, while excessive force can damage the shell, affecting subsequent processing. The shell removal process presents even greater problems. Workers must use small pry bars or peel the shells by hand, which is not only physically demanding and prone to hand injuries, but also results in significant variations in the precision of handling the connection between the shell and body. Gill removal and cutting into pieces also require substantial manpower and struggle to ensure uniformity in size. Therefore, a swimming crab processing device is urgently needed to address these technical problems. Utility Model Content

Considering the variations in swimming crab size, which makes it difficult to simply clamp the crab legs, a clamping device is used to hold the crab body, leaving the legs exposed. As the crab is transported by the transmission device, the exposed legs are cut off by the first and second blades, ensuring the integrity of both the legs and body. This innovative method of clamping the crab body while exposing the legs avoids the difficulty of clamping crabs with varying leg thicknesses and lengths. Regardless of the size of the swimming crab, the clamping device can stably fix its core body area, ensuring that subsequent processes accurately target the desired areas, resulting in greater adaptability. The leg-removing device uses rotating blades on both sides to cut the exposed crab legs. The cutting action only acts on the connection between the crab legs and the body, avoiding damage to the crab meat. At the same time, the mechanical cutting force is uniform, and compared with manual tearing, the broken surface of the crab legs is flat and not easily broken, greatly improving the integrity of the finished crab body and legs. The gill-removing components, blades, lifting components, and cutting blades are all set according to fixed trajectories and positions, and the execution parameters (such as cutting depth, lifting angle, and cutting position) of each processing step are kept uniform.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] The purpose of this invention is to provide a swimming crab processing device to solve the problems existing in the prior art, enabling mechanized processing of swimming crabs and ensuring high specification consistency.
[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] like Figures 1-2 As shown, this utility model provides a swimming crab processing device, including a conveying device 1, a clamping device 2, a gill removal device 4, a leg removal device 3, a shell removal device 5, and a cutting device 6. The conveying device 1 is connected to a first driving device and is used to convey swimming crabs. The clamping device 2 is fixedly mounted on the conveying device 1 and is used to clamp the body of the swimming crab, with the legs of the crab exposed outside the clamping device 2 and extending out of the side of the conveying device 1. The gill removal device 4 includes a first gill removal component 41 and a second gill removal component 44, which are located on both sides of the conveying device 1, and are capable of processing the gills. The swimming crabs on the conveyor device 1 undergo gill removal; the leg removal device 3 includes a first blade 31 and a second blade 32, which are located on both sides of the conveyor device 1 and can rotate around their own axis; the shell removal device 5 is located at the end of the conveyor device 1 and includes a lifting component, which includes a lifting rod 51 that can extend into the inside of the swimming crab shell and pry it open; the cutting device 6 includes a cutter located above or below the conveyor device 1 and at the midpoint of the width direction of the conveyor device 1, which can cut the swimming crabs held by the clamping device 2.
[0022] On a single production line, the gills, legs, shell, and pieces of swimming crabs are removed, all mechanized, ensuring high consistency in specifications. Considering the variations in crab size and the short legs, which make it difficult to hold the crab legs securely, a clamping device 2 is used to hold the crab body, leaving the legs exposed. As the crab is transported by the transmission device, the exposed legs are cut off by the first blade 31 and the second blade 32, ensuring the integrity of both the legs and body. This innovative method of clamping the crab body while exposing the legs avoids the difficulties caused by varying leg thickness and length. Regardless of the crab's size, the clamping device 2 can stably hold the core area of its body, ensuring that subsequent processes precisely target the desired areas, offering greater adaptability. The leg-removing device 3 uses rotating blades on both sides to cut the exposed crab legs. The cutting action only acts on the connection between the crab legs and the crab body, avoiding damage to the crab meat. At the same time, the mechanical cutting force is uniform, and compared with manual tearing, the broken surface of the crab legs is flat and not easily broken, greatly improving the integrity of the finished crab body and legs. The gill-removing components, blades, lifting components, and cutters are all set according to fixed trajectories and positions, and the execution parameters of each processing step (such as cutting depth, lifting angle, and cutting position) remain uniform. For example, the cutter of the dicing device 6 is fixed at the midpoint of the width direction of the conveyor device 1, ensuring that each swimming crab is cut symmetrically or to a preset size, effectively solving the problems of inconsistent size and uneven cuts in manual processing, and ensuring a high degree of consistency in product specifications.
[0023] In some embodiments, the clamping device 2 includes a first clamping claw 21 and a second clamping claw 22. Both the first clamping claw 21 and the second clamping claw 22 are preferably arc-shaped, forming an embracing posture from both sides of the crab's body. The clamping force can be evenly applied to the surface of the crab's body. The ends of the first clamping claw 21 and the second clamping claw 22 are rotatably connected. This rotatable connection allows the two claws to open and close flexibly around a rotation axis, creating an adjustable opening angle similar to scissors. When dealing with swimming crabs of different sizes and shapes, the two claws can adjust the opening and closing range according to the actual width of the crab's body. It should be noted that the two claws can be locked using friction. During use, they must be manually pried open, the swimming crab placed inside, and then manually closed again.
[0024] In some embodiments, the clamping device 2 further includes a fixing plate 23, preferably a perforated plastic plate. The rotational connection point between the first gripper 21 and the second gripper 22 is located on the fixing plate 23. The first gripper 21 and the second gripper 22 can form a circumferential rotational and axially fixed connection with the fixing plate 23. The fixing plate 23 is fixedly mounted on the conveying device 1. As the bearing base of the gripper, the fixing plate 23 integrates the originally independent first gripper 21 and second gripper 22 into a modular component, avoiding possible installation misalignment when the gripper is directly connected to the conveying device 1. At the same time, by fixing the fixing plate 23 as a whole to the conveying device 1, it disperses the mechanical force (such as the reaction force generated by cutting and picking) borne by the gripper during processing, reduces local wear on the conveying device 1 itself, and extends the overall life of the equipment. The presence of the fixing plate 23 does not restrict the opening and closing freedom of the gripper. On the contrary, through stable rotational support, it makes the opening and closing action of the gripper smoother and the clamping force more uniform when facing swimming crabs of different sizes. Especially for crabs with irregular shapes, the grippers can flexibly adjust their angle based on the fixed plate 23, and combined with the embracing gripping feature, further improve gripping stability and reduce crab shaking during processing. During the processing of swimming crabs, impurities such as body fluids and shell fragments are generated. The perforated structure prevents these impurities from accumulating on the surface of the fixed plate 23, and the smooth surface of the plastic material does not easily adhere to seafood impurities. Furthermore, the plastic plate is water-resistant and resistant to mild corrosion, allowing for direct rinsing during cleaning without complicated procedures, meeting the hygiene standards of the food processing industry and reducing cleaning and maintenance costs.
[0025] In some embodiments, the conveying device 1 includes a circular conveyor belt, a leg-removing device 3 located on the upper side of the circular conveyor belt, a slicing device 6 located directly below the circular conveyor belt, and a gill-removing device 4 located on the lower side of the circular conveyor belt. This design breaks away from the traditional approach of concentrating all devices on the same plane of the conveyor belt. Through a three-dimensional distribution of the upper side, directly below, and lower side, the three major processing steps are dispersed across different spatial dimensions of the circular conveyor belt. For example, the leg-removing device 3 processes exposed crab legs at the top, the gill-removing device 4 simultaneously acts on both sides of the crab body at the lower side, and the slicing device 6 completes the cutting at the lower side. This eliminates the need for lengthy process intervals on a flat surface, significantly reducing the overall footprint of the production line, making it particularly suitable for industrial settings with limited factory space.
[0026] In some embodiments, the swimming crab processing device further includes a side plate and a first bevel gear 8. The side plate is fixedly disposed on the side of the conveying device 1, and the first bevel gear 8 is rotatably connected to the side plate. The first driving device includes a drive motor and an intermediate transmission rod 7. The intermediate transmission rod 7 is horizontally disposed and its length direction is consistent with the length direction of the conveying device 1. The intermediate transmission rod 7 has a second bevel gear 72 and a third bevel gear 74. The second bevel gear 72 is meshed with the first bevel gear 8. The output shaft of the first driving device is connected to a first pulley. The gear shaft of the first bevel gear 8 is connected to a second pulley. The first pulley and the second pulley are connected by a first synchronous belt. The first blade 31 and the second blade 32 are fixedly disposed on the blade shaft 33. The end of the blade shaft 33 is fixedly disposed with a fourth bevel gear 34, and the fourth bevel gear 34 is meshed with the third bevel gear 74. The drive motor serves as the sole power source, simultaneously supplying power to both the conveying device 1 and the leg-removing device 3 via a combination of synchronous belt and bevel gear set. The motor output shaft drives the first bevel gear 8 to rotate via the first pulley, the first synchronous belt, and the second pulley. The first bevel gear 8 then drives the intermediate transmission rod 7 to rotate via the second bevel gear 72 on the intermediate transmission rod 7. The intermediate transmission rod 7, in turn, drives the blade shaft 33 and the first and second blades 31 to rotate via the third and fourth bevel gears 34. This eliminates the need for separate drive motors for the conveying device 1 and the leg-removing device 3, simplifying the equipment structure, reducing energy consumption, and ensuring a high degree of matching between the operating rhythms of the two devices (conveyor speed and blade speed), thus avoiding processing misalignment caused by independent power sources (such as incomplete crab leg cutting due to mismatch between blade speed and conveyor speed). The first bevel gear 8 meshes with the second bevel gear 72, and the third bevel gear 74 meshes with the fourth bevel gear 34. By utilizing the core characteristic of bevel gears that can change the direction of power transmission, the conversion of power between the horizontal direction (intermediate transmission rod 7) and the vertical inclined direction (shaft of the first bevel gear 8 and blade shaft 33) is realized.
[0027] It should be noted that a gear transmission device can also be set up, with different specifications of gears meshing to change the transmission ratio. For example, the output shaft of the drive motor is connected to a gear with a larger diameter, which then meshes with a gear with a smaller diameter. A first pulley is set on the gear shaft of the smaller gear. To increase output smoothness and transmission performance, the drive motor is connected to a speed reducer.
[0028] In some embodiments, the swimming crab processing device further includes a gill removal transmission rod, which is arranged perpendicular to the intermediate transmission rod 7, and its end is rotatably connected to a side plate. A first conical worm gear 71 is also provided on the intermediate transmission rod 7, and a first conical worm wheel 43 is fixedly provided on the gill removal transmission rod. The first conical worm wheel 43 meshes with the first conical worm gear 71. Both the first gill removal component 41 and the second gill removal component 44 include roller brushes. The roller brush shafts 42 of both roller brushes are fixedly connected to third pulleys. A fourth pulley is fixedly provided on the gill removal transmission rod, and both third pulleys are connected to the fourth pulley via a second synchronous belt. When the clamping device 2 clamps the swimming crab, its back is against the fixing plate 23, and its belly is exposed, facilitating gill removal. Power is directly obtained from the drive motor (single power source) by means of the engagement between the first conical worm gear 71 on the intermediate transmission rod 7 and the first conical worm wheel 43 on the gill removal transmission rod, eliminating the need for an additional independent motor for the gill removal device 4. This design integrates the power requirements of the conveyor device 1, leg removal device 3, and gill removal device 4 into a single drive chain. This reduces the number of motors in the equipment, lowers energy consumption and manufacturing costs, and ensures strict synchronization of the operating rhythms of the three devices (conveyor speed, blade speed, and roller brush speed). The gills of the swimming crab are symmetrically distributed on both sides of the crab's body. The two roller brushes correspond to the gill positions on both sides of the conveyor device 1, and are driven by the same gill removal transmission rod and synchronous belt, achieving synchronous rotation and action on both sides. The symmetrical drive method ensures that the peeling force on both sides of the gills is consistent, resulting in uniform removal. This solves the problem of uneven cleaning on both sides when manually removing gills or using a single-side drive, and improves the standardization of the product.
[0029] It should be noted that the gill removal device 4 can also use other types of devices, such as suction nozzles or spray nozzles, as long as the crab gills can be effectively removed.
[0030] In some embodiments, the swimming crab processing device further includes a second conical worm gear 63, the worm gear shaft of which is rotatably connected to a side plate. A second conical worm 73 is also provided on the intermediate transmission rod 7. The second conical worm gear 63 and the second conical worm 73 are meshed together. A fifth pulley is fixedly provided on the worm gear shaft of the second conical worm gear 63. The cutter includes a fixedly connected roller blade 61 and a cutter shaft 62. The cutter shaft 62 is rotatably connected to the side plate. A sixth pulley is fixedly provided on the cutter shaft 62. The fifth pulley and the sixth pulley are connected by a third synchronous belt. By meshing the second conical worm 73 and the second conical worm gear 63 on the intermediate transmission rod 7, the power of the drive motor is extended to the cutting device 6, so that the four core modules of the conveying device 1, the leg removal device 3, the gill removal device 4, and the cutting device 6 share the same power source. There is no need to configure an additional independent motor for the cutting device 6, which greatly simplifies the power layout of the equipment, reduces the number of motors and energy consumption, and fundamentally ensures that the operating rhythm of all processing steps (conveyor speed, blade speed, roller speed, and roller cutter speed) is strictly synchronized. It should be noted that the height of the roller blade 61 is set so that it will only cut to the crab body and will not cut to the fixed plate 23.
[0031] In some embodiments, the agitator assembly further includes a first transmission rod, a second transmission rod, and a guide sleeve. The first transmission rod is hinged to the second transmission rod. A seventh synchronous pulley is fixedly mounted on the end side of the first transmission rod. An eighth synchronous pulley is fixedly mounted on the output shaft of a separately configured second drive device (different from the first drive device of the conveyor belt). The seventh and eighth synchronous pulleys are connected by a fourth synchronous belt. The end of the second transmission rod away from the first transmission rod is hinged to the agitator 51. The guide sleeve is fixedly connected to a side plate and has a guide hole. The length direction of the guide hole is consistent with the length direction of the conveyor 1, allowing the agitator 51 to pass through the guide hole, ensuring that the pressure angle is zero. The first and second transmission rods are hinged to form a movable linkage mechanism. When the first transmission rod rotates under the drive of the synchronous belt pulley, the circular motion at its end is converted into the reciprocating motion of the lifting rod 51 through the second transmission rod. The motion trajectory can precisely adapt to the structural characteristics of the crab shell: the lifting rod 51 first smoothly extends into the gap of the crab shell along the guide hole, then applies an outward lifting force through the angle change of the hinge rod, and finally returns to its original position with the connecting rod. The whole process can be completed without complex multi-axis drive, which can avoid tearing damage to the crab meat to a certain extent. The guide hole of the guide sleeve is set along the length of the conveying device 1. After the lifting rod 51 passes through the guide hole, its movement direction is strictly limited to a straight line parallel to the conveying direction, ensuring that the lifting rod 51 is always aligned with the preset insertion point of the crab shell (such as the connection gap between the crab body and the crab shell). The lifting rod 51 will not be offset or tilted due to the movement error of the hinge rod group or the vibration of the equipment, which effectively solves the problems of empty lifting (not extending into the gap) or tilting (puncturing the crab meat), and greatly improves the success rate of shell removal.
[0032] In some embodiments, a wedge-shaped block is fixedly provided at the end of the agitator 51 away from the second transmission rod. The slope of the wedge-shaped block gradually increases in height from the end away from the second transmission rod to the end closer to the second transmission rod. There is a narrow connecting gap between the crab shell and the crab body. The tip of the wedge-shaped block (the end away from the second transmission rod) is slender and can be easily aligned and inserted into the gap. As the agitator 51 is advanced along the guide hole, the slope of the wedge-shaped block gradually thickens (increases in height), which can naturally open the gap and provide sufficient force space for subsequent agitation actions.
[0033] In some embodiments, the roller brush includes a frustum and a brush body. The brush body is fixedly attached to the frustum, which is fixedly connected to the roller brush shaft 42. The smaller end of the frustum is close to the middle of the conveying device 1, and the larger end is close to the side of the conveying device 1. The smaller ends of the two frustums face each other. The conical profile closely matches the arcuate profile of the crab's side. The brush body fixed to the frustum can conform to the growth area of the crab's gills for gill removal. Different sizes of swimming crabs have different widths and curvatures on their sides. The conical surface of the frustum has a gradually changing contact range. For small swimming crabs, cleaning can be completed by only the brush body near the smaller end of the frustum contacting the crab's gills. For large swimming crabs, the brush body at the larger end of the frustum can adapt to their wider side, without adjusting the position or spacing of the roller brush, and can accommodate individual differences through the natural transition of the conical surface.
[0034] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
