DETAILED DESCRIPTION

[0023] The embodiments of the present application will be described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application. All other examples obtained by those skilled in the art without creative labor are within the scope of the present application.

[0024] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 , a Portunus trituberculatus automatic cage releasing device comprises a workbench 1, the workbench 1 is provided with a transmission belt 2, the transmission belt 2 is provided with a crab cage feeding mechanism 3, a Portunus trituberculatus cage releasing mechanism 4 and a discharge mechanism 5; the crab cage feeding mechanism 3 is used for conveying the crab cage containing Portunus trituberculatus to the Portunus trituberculatus cage releasing mechanism 4; the Portunus trituberculatus cage releasing mechanism 4 is used for releasing Portunus trituberculatus in the crab cage; and the discharge mechanism 5 is used for conveying the released Portunus trituberculatus and the processed crab cage to the next processing link respectively.

[0025] The utility model provides a device for automatically removing the cages of swimming crabs, which is used to improve the efficiency and automation level of the processing flow of swimming crabs. The workbench 1 serves as the basic support platform of the entire device, ensuring the stability and durability of the entire cage removal process. The transmission belt 2 is installed on the workbench 1 and serves as the link between the crab cage feeding mechanism 3, the swimming crab cage removal mechanism 4, and the discharging mechanism 5. The transmission belt 2 ensures the safety of contact with the swimming crabs, and its running speed can be adjusted to adapt to different production needs, ensuring the smoothness and efficiency of the swimming crab processing process.

[0026] The crab cage feeding mechanism 3 is responsible for feeding the cages filled with swimming crabs from the external system. The crab cage feeding mechanism 3 uses a mechanical arm or a conveyor belt to feed the cages one by one, ensuring that each cage is placed at the designated position on the transmission belt 2, preparing for the subsequent cage removal operation.

[0027] The swimming crab cage removal mechanism 4 uses vibration, air pressure, or mechanical extrusion to gently and effectively separate the swimming crabs from the cages. To avoid causing harm to the swimming crabs, the swimming crab cage removal mechanism 4 ensures that the impact on the swimming crabs during the cage removal process is minimized.

[0028] After the cage removal is completed, the swimming crabs and the empty crab cages are output through the discharging mechanism 5. The discharging mechanism 5 may include two parallel transmission belts 2, one for transporting the swimming crabs to the subsequent cleaning, grading, or packaging steps, and the other for sending the empty crab cages back to the recycling or reuse area. To ensure the orderly output of the swimming crabs and the crab cages.

[0029] In combination with Figure 2 , Figure 3 , Figure 5 and Figure 6 , the swimming crab cage removal mechanism 4 includes a mounting bracket 42 installed on the transmission belt 2, which not only ensures the stability of the mechanism but also facilitates subsequent maintenance and adjustment.

[0030] The feeding end of the mounting bracket 42 is provided with a crab cage clamping mechanism 43, which is responsible for clamping the crab cages coming from the transmission belt 2, providing stable support for the subsequent opening and vibration removal operations.

[0031] The lower part of the crab cage clamping mechanism 43 is provided with an opening mechanism 41, which functions to gradually open the cage door or cage net of the crab cage through mechanical or air pressure after the crab cage is clamped stably, creating the necessary space for the removal of the swimming crabs.

[0032] The crab cage clamping mechanism 43 has a vibration lifting mechanism 44 for driving its lifting and vibration. The vibration lifting mechanism 44 drives the crab cage clamping mechanism 43 to lift and vibrate, which helps to loosen and remove the blue crab from the crab cage. The vibration lifting mechanism 44 can effectively promote the removal of the blue crab through appropriate vibration frequency and amplitude, while avoiding unnecessary damage to the blue crab.

[0033] In combination Figure 2 , Figure 3 , Figure 6 and Figure 7 , the vibration lifting mechanism 44 includes a lifting motor 441 arranged at the top end of the mounting frame 42, which can provide stable and powerful power output. The output end of the lifting motor 441 is connected with a rotating roller 442 through a transmission belt, which can convert the power of the lifting motor 441 into rotary motion. The two ends of the rotating roller 442 are connected with the crab cage clamping mechanism 43 through a transmission belt, so that the power of the lifting motor 441 can be directly transmitted to the crab cage clamping mechanism 43 to drive it to lift and vibrate.

[0034] During the operation of the vibration lifting mechanism 44, the lifting motor 441 is started, and its output end drives the rotating roller 442 to rotate through the transmission belt. The rotary motion of the rotating roller 442 is transmitted to the crab cage clamping mechanism 43 through the transmission belt, so that it can lift and vibrate. At the same time, due to the elastic properties of the transmission belt, when the rotating roller 442 rotates, it will also produce a certain vibration effect, which helps to loosen and remove the blue crab from the crab cage.

[0035] In combination Figure 2 , Figure 3 , Figure 6 and Figure 7 , the crab cage clamping mechanism 43 includes a fixed plate 431 arranged on the mounting frame 42, which ensures good mechanical properties and stability during long-term use. The fixed plate 431 is provided with a rotary motor 432 at the center of the front surface, which can provide stable and continuous power output.

[0036] The output end of the rotary motor 432 is connected with a rotary gear 433, which ensures efficient transmission of power. The rotary gear 433 is arranged on the front surface of the fixed plate 431, and the upper and lower sides of the rotary gear 433 are provided with sliding grooves 434. The sliding grooves 434 are slidably connected with toothed strips 435, which provide good guidance and support for the sliding of the toothed strips 435. The cooperation between the toothed strips 435 and the sliding grooves 434 ensures the stability and reliability of the toothed strips 435 during sliding.

[0037] The opposite sides of the front of the fixed plate 431 are provided with crab cage clamping claws 436, one end of the toothed strip 435 is fixedly connected with the end of the crab cage clamping claw 436, and the rack of the toothed strip 435 is in meshing connection with the rotating gear 433.

[0038] One end of the toothed strip 435 is fixedly connected with the end of the crab cage clamping claw 436, so that the rotation of the rotating gear 433 can directly drive the crab cage clamping claw 436 to perform opening and closing movement. The crab cage clamping claw 436 ensures that the crab cage can be firmly clamped, while avoiding damage to the crab cage.

[0039] When the rotating motor 432 starts, its output end drives the rotating gear 433 to rotate. The rotation of the rotating gear 433 drives the toothed strip 435 to slide in the sliding groove 434 through the cooperation of the toothed strip 435 and the sliding groove 434. Since one end of the toothed strip 435 is fixedly connected with the crab cage clamping claw 436, the sliding of the toothed strip 435 will drive the crab cage clamping claw 436 to perform opening and closing movement.

[0040] In combination with Figure 1 , Figure 2 and Figure 4 , the crab cage feeding mechanism 3 includes a fixing frame 31 arranged on the workbench 1, which ensures the stability and durability of the mechanism. The fixing frame 31 is provided with a gas cylinder 32, which can provide stable and powerful power output. The output end of the gas cylinder 32 is connected with a turnover clamp 33. The turnover clamp 33 can firmly clamp the crab cage and maintain the stability of the crab cage during the turnover process.

[0041] During the work process, when the crab cage is placed at the designated position in front of the fixing frame 31, the gas cylinder 32 starts and drives the turnover clamp 33 to move forward and clamp the crab cage. Then, the gas cylinder 32 continues to output power to drive the turnover clamp 33 to perform a turnover action, turning the crab cage from a horizontal position to a vertical position and accurately feeding it into the decaging mechanism.

[0042] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 5 , the discharging mechanism 5 includes a remiped crab discharging belt 51 and a crab cage discharging belt 52; the remiped crab discharging belt 51 is arranged below the spreading mechanism 41 and is used for conveying the remiped crab after decaging; the crab cage discharging belt 52 is arranged on the back of the fixed plate 431 and is used for conveying the crab cage after decaging.

[0043] The discharging mechanism 5 is responsible for conveying the remiped crab and the crab cage after decaging to the subsequent processing process, respectively.

[0044] The shuttle crab discharging belt 51 is arranged below the opening mechanism 41, fully considering the natural landing point and movement trajectory of the shuttle crab after it is discharged from the crab cage. The shuttle crab discharging belt 51 can ensure the stability and safety of the shuttle crab during transmission.

[0045] The crab cage discharging belt 52 is arranged on the back of the fixed plate 431, so that the crab cage can directly fall onto the crab cage discharging belt 52 after completing the discharging operation, avoiding cross interference with the shuttle crab. The crab cage discharging belt 52 ensures the stability and reliability of the crab cage during transmission.

[0046] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , the transmission belt 2 includes a flat belt transmission belt 21 arranged on the workbench 1, which can ensure that the crab cage remains stable and is not easy to slip during transmission. The discharging end of the flat belt transmission belt 21 is connected with a timing transmission belt 22, which ensures the stability and accuracy of the crab cage during transmission.

[0047] A funnel-shaped discharging chute 23 is arranged in the middle of the timing transmission belt 22, which ensures that the shuttle crab can smoothly and accurately fall into the discharging chute 23. The outlet of the discharging chute 23 is directly above the shuttle crab discharging belt 51, so that the shuttle crab can directly fall onto the crab cage discharging belt 52 after completing the discharging operation, avoiding cross interference with the crab cage, and improving the transmission efficiency.

[0048] In combination with Figure 3 , Figure 5 and Figure 8 , the opening mechanism 41 includes a mounting bracket 411 arranged inside the discharging chute 23, which serves as the main structure of the opening mechanism 41, ensuring the stability and durability of the mechanism. The mounting bracket 411 is provided with an opening clamp 412 for opening the crab cage mesh, and the end of the opening clamp 412 adopts a special shape and structure, which can fit the crab cage mesh and open it through appropriate clamping force.

[0049] The end of the opening clamp 412 is provided with an anti-slip block 413 for increasing friction and protecting the crab cage mesh. The anti-slip block 413 can increase the friction between the opening clamp 412 and the crab cage mesh, preventing the crab cage mesh from slipping or deforming during the opening process. At the same time, the surface of the anti-slip block 413 is also specially treated, having excellent wear resistance and corrosion resistance, which can protect the crab cage mesh from damage.

[0050] The utility model discloses preferable specific implementation, but the protection scope of the utility model is not limited to this, any person skilled in the art in the utility model disclosed technical range, according to the utility model technical scheme and its utility model concept are equivalent to replace or change, all should be covered in the protection scope of the utility model.
