[0026] By designing multiple concave channels on the partition plate of the screening container, under the shaking of the shaking drive unit, due to the self-gravity of the crabs, during the shaking process, because the top area of the partition plate is too small, the contact area between the crabs and it is small. After the center of gravity of the crabs changes, they will automatically slide into the concave channels to complete the screening arrangement. Subsequently, under the cooperation of the tilting drive unit and the baffle drive unit, the crabs are poured from the concave channels into the corresponding accommodating cavities of the conveying mechanism. Then, under the drive of the conveying drive unit, multiple partition plates push the crabs in the corresponding accommodating cavities to move along the conveying track to the bundling mechanism in sequence. The bundling mechanism bundles the screened crabs. Thus, the process of bundling after fishing can be automatically completed without manual participation, and the screening arrangement, conveying, and bundling of crabs are fully automated. During the conveying process, the crabs will not be in chaos and can be released one by one for bundling.

[0042] Please refer to Figures 1 to 7 , this embodiment provides a crab bundling device, including: a screening mechanism 1, a conveying mechanism 2 and a bundling mechanism 3; wherein:

[0043] Please refer to Figure 2 With Figure 3 , the screening mechanism 1 includes a screening container 11, a shaking driving unit 12, a dumping driving unit 13, and a baffle driving unit 14. The screening container 11 includes a receiving frame 111 with a notch on one side, a baffle 112 movably arranged vertically at the notch, and a plurality of partition plates 113 arranged at the bottom of the receiving frame 111. The plurality of partition plates 113 are arranged in parallel at intervals, so as to form a plurality of concave flow channels 114 for conveying along the notch direction at the bottom of the receiving frame 111. Among them, the distance between the partition plates 113, that is, the width of the concave flow channel 114, is 1.1 - 1.3 times the width of the crab.

[0044] The shaking driving unit 12 is used to drive the sieve container 11 to shake, so that the crabs located in the accommodation frame 111 slide into the concave channel 114 for sieving and arranging. The tilting driving unit 13 is used to tilt and pour out the crabs in the concave channel 114 towards the notch. The baffle driving unit 14 is used to cooperate with the tilting operation of the tilting driving unit 13. Specifically, when the accommodation frame 111 tilts under the drive of the tilting driving unit 13, it drives the baffle 112 to lift to create an outlet for the crabs in the concave channel 114, so that the crabs that have been sieved by the concave channel 114 can enter the conveying mechanism 2 respectively.

[0045] The conveying mechanism 2 includes a conveying track 21, a spacing component 22, and a conveying driving unit 23. The spacing component 22 includes a plurality of spacing plates 221 and a conveying rod 222 for installing the spacing plates 221. The plurality of spacing plates 221 divide the conveying track 21 into accommodation cavities 223 corresponding one-to-one to the concave channels 114. The accommodation cavities 223 are used to receive the crabs that are tilted and poured out from the notch. The conveying driving unit 23 is used to drive the conveying rod 222 to move step by step along the conveying track 21 towards the bundling mechanism 3, so that the spacing plates 221 installed on the conveying rod 222 push the crabs in the corresponding accommodation cavities 223 to move along the conveying track 21 to the bundling mechanism 23 in sequence.

[0046] The bundling mechanism 23 is used to bundle the crabs that move from the conveying mechanism 2 to the bundling mechanism 2.

[0047] In this embodiment, a plurality of concave channels 114 are designed by the partition plate 113 of the sieve container 11. Under the shaking of the shaking driving unit 12, due to the self-gravity of the crabs, during the shaking process, since the top area of the partition plate 114 is too small, the contact area between the crabs and it is small. After the center of gravity of the crabs changes, they will automatically slide into the concave channel 114 to complete the sieving and arranging. Subsequently, under the cooperation of the tilting driving unit 13 and the baffle driving unit 14, the crabs are poured from the concave channel 114 into the corresponding accommodation cavities 223 of the conveying mechanism 2. Subsequently, under the drive of the conveying driving unit 23, a plurality of spacing plates 222 push the crabs in the corresponding accommodation cavities 223 to move along the conveying track 21 to the bundling mechanism 3 in sequence. The bundling mechanism 3 bundles the sieved crabs. Thus, the process of bundling after fishing can be automatically completed without manual participation, and the sieving, arranging, conveying, and bundling of crabs are fully automated.

[0048] Please refer to Figure 2, in this embodiment, the shaking driving unit 12 includes a frame 121, a first hydraulic cylinder 122, a fixed platform 123, an I-shaped rod 124, and a plurality of support rods 125. The fixed platform 123 is used to mount the screening container 11. The middle part of the support rod 125 is rotatably connected to the frame 121. The upper end of the support rod 125 is hinged to the fixed platform 123, and the lower end of the support rod 125 is hinged to the I-shaped rod 124. A plurality of support rods 125 are respectively installed on both sides of the I-shaped rod 124 and the fixed platform 123.

[0049] The first hydraulic cylinder 121 is hinged to the middle rod of the I-shaped rod 124. Thus, when the first hydraulic cylinder 121 makes a linear reciprocating motion, it can drive the support rod 125 to rotate with the middle connection point as the fulcrum, and further make the fixed platform 123 shake reciprocally, driving the screening container 11 mounted on the fixed platform 123 to shake.

[0050] In this embodiment, the tilting driving unit 13 includes a second hydraulic cylinder whose two ends are respectively hinged to the fixed platform 123 and the receiving frame 111, and the second hydraulic cylinder is hinged to the bottom surface position of the receiving frame 111 far from the notch. The position of the bottom surface of the receiving frame 111 close to the notch is hinged to the fixed platform 123. Thus, when the second hydraulic cylinder makes a linear extension motion, it will lift the receiving frame 111 on the side far from the notch, enabling the receiving frame 111 to tilt the crabs inside; when the second hydraulic cylinder makes a linear retraction motion, it will make the receiving frame 111 gradually lie flat on the fixed platform 123.

[0051] Further preferably, through the coordinated actions of the tilting driving unit 13 and the baffle driving unit 14, each concave flow channel 111 of the receiving frame 111 is controlled to pour crabs into the receiving cavity 223 of the conveying mechanism 2 one by one. Especially when each concave flow channel 111 pours one crab into the receiving cavity 223, the baffle driving unit 14 immediately descends to block the outlet of the concave flow channel 111. Also, by setting the size of the receiving cavity 223, it can be controlled to only hold one crab inside.

[0052] Please refer to Figure 2 , in this embodiment, the baffle driving unit 14 includes two third hydraulic cylinders. The two third hydraulic cylinders are respectively arranged on the side walls of the receiving frame 111 on both sides of the notch. One end of the third hydraulic cylinder is connected to the receiving frame 111, and the other end of the third hydraulic cylinder is connected to the baffle 112. In this embodiment, chutes adapted to the two ends of the baffle 112 are provided on the side walls of the receiving frame 111. Under the push of the third hydraulic cylinder, the baffle 112 slides up and down in the chutes, thus playing a role similar to opening and closing a door.

[0053] Please refer to Figure 4 And Figure 5, the conveying drive unit 23 includes a fourth hydraulic cylinder, one end of the fourth hydraulic cylinder is connected to the conveying track 21, and the other end of the fourth hydraulic cylinder is connected to the conveying rod 221.

[0054] Further, the conveying mechanism 2 further includes a first fixing seat 24, a second fixing seat 25 and a fifth hydraulic cylinder 26. The top of the first fixing seat 24 is hinged to one end of the conveying track 21 away from the bundling mechanism 3. One end of the fifth hydraulic cylinder 26 is hinged to the second fixing seat 25, and the other end is hinged to a position on the bottom surface of the conveying track 21 away from the first fixing seat 24. When the fifth hydraulic cylinder 26 retracts, the conveying track 21 inclines and descends towards the bundling mechanism 3, so as to better cooperate with the conveying drive unit 23 to move the crabs in the accommodating cavity 223 to the bundling platform 3.

[0055] Please refer to Figure 6 and Figure 7 , the bundling mechanism 3 includes a bundling platform 31, a fixing drive unit 32, a rotating drive unit 22, a motor driver 34, a cotton rope storage 35 and a bundling rope outlet 36; the bundling platform 31 is used to receive the crabs from the conveying mechanism 2, the fixing drive unit 32 is used to move the crabs on the bundling platform 31 to the bundling position for fixing, the bundling rope outlet 36 is used to bundle the crabs with the cotton rope in the cotton rope storage 35 under the rotational drive of the motor driver 34, and the rotating drive unit 33 is used to rotate the crabs on the already bundled side by 90° to complete the cross bundling of the crabs.

[0056] Specifically, the rotating drive unit 33 includes a robotic arm 331, a robotic claw 332, and a lifting and rotating driver. One end of the robotic arm 331 is fixed on the bundling platform 31, and the robotic claw 332 is connected to the other end of the robotic arm 331 through the lifting and rotating driver. When one side of the crab fixed by the fixing drive unit 32 is bundled, the robotic claw 332 grabs the crab downward under the control of the lifting and rotating driver, the fixing drive unit 32 releases the crab, the robotic claw 332 horizontally rotates the crab by 90 degrees under the control of the lifting and rotating driver, the fixing drive unit 32 continues to fix the crab, and the robotic claw 332 rises under the control of the lifting and rotating driver to avoid interfering with the bundling operation; the bundling rope outlet 36 bundles the other side of the crab to complete the cross bundling.

[0057] In this embodiment, the fixed driving unit 32 includes a sixth hydraulic cylinder 321, a seventh hydraulic cylinder 322, a first arc-shaped pusher 323, a second arc-shaped pusher 324, and a third arc-shaped pusher 325. The first arc-shaped pusher 323, the second arc-shaped pusher 324, and the third arc-shaped pusher 325 all have arc-shaped surfaces for pushing crabs. The sixth hydraulic cylinder 321 is used to push the crabs falling onto the bundling platform 31 to the second arc-shaped pusher 324 through the first arc-shaped pusher 323. The seventh hydraulic cylinder 322 is used to push the crabs to the bundling position through the second arc-shaped pusher 324. The third arc-shaped pusher 325 is used to cooperate with the second arc-shaped pusher 324 to fix the crabs at the bundling position.

[0058] In this embodiment, further, in order to bundle crabs more efficiently, the device further includes a flipping mechanism 37. The flipping mechanism 37 includes an eighth hydraulic cylinder 371, a flat pusher 372, a flipping box body 373, and a flipping driving unit 374. The seventh hydraulic cylinder 321 pushes the crabs to be flipped to the position of the flat pusher 372 through the second arc-shaped pusher 324. The eighth hydraulic cylinder 371 pushes the crabs into the flipping box body 373 through the flat pusher 372. The flipping driving unit 374 is used to rotate the flipping box body 180°. The flipping box body 373 is inclined downward so that when the eighth hydraulic cylinder 371 drives the flat pusher 372 away from the flipping box body, the crabs in the flipping box body 373 can slide back onto the bundling platform. The flipping mechanism 37 can cooperate with a sensor. When it senses that the current crab is facing upwards with its belly, it uses the flipping mechanism 37 to flip it so that its back is facing upwards. If the sensor senses that the current crab is facing upwards with its back, there is no need to flip it.

[0059] In other preferred embodiments, the tabletop of the bundling platform 31 is inclined downward away from the conveying mechanism 2, and the end of the bundling platform 31 away from the conveying mechanism 2 has a baffle to prevent crabs from falling. The tabletop of the bundling platform 31 is smoothly arranged, so that the crabs falling onto the tabletop of the bundling platform 31 will naturally gather at the baffle, which is convenient for the sixth hydraulic cylinder 321 to push the crabs to the second arc-shaped pusher 324 through the first arc-shaped pusher 323, or to the position of the flat pusher 372 of the flipping mechanism 37, and is also convenient for the crabs sliding in from the flipping box body 373 to slide to the baffle position on the tabletop of the bundling platform 31.

[0060] This embodiment also provides a bundling method using the above bundling device, including the following steps:

[0061] S1: Put the crabs into the accommodating frame 111.

[0062] S2: Trigger the shaking driving unit 12 so that the crabs slide into the concave flow channel 114 for screening and arranging.
