After the hairy crab slides from the feed inlet 12 to the top of the unloading plate 13, it will slide to the bottom along the unloading plate 13. Then the second hairy crab slides onto the unloading plate 13 and moves to the side of the first hairy crab, and stacks up in sequence until the surface of the unloading plate 13 is full of hairy crabs. At this time, the conveying mechanism 2 stops working; then the second linear motor drives the slide bar 17 to drive the driving frame 11 and the unloading plate 13 to move downward synchronously, and the frame 11 and the unloading plate 13 move into the packaging box 14; until the slide bar 17 moves to contact the first slider 23 on the first positioning plate 18, the slide bar 17 continues to move downward to drive the first slider 23 to move downward, and the first slider 23 will The wedge-shaped limit block 21 located above it is driven to move downward by the first traction rope 22 to cancel the limit on the second positioning plate 19 at the bottom, and then the second positioning plate 19 at the bottom will pop out to the side close to the slide bar 17 under the elastic force of the reset spring 20; at this time, the material frame 11 is close to the unloading position, and when the slide bar 17 continues to move downward, the first positioning plate 18 will drive the second sliding block 26 to move upward relative to the slide bar 17, and the second sliding block 26 will drive the block 24 to move outward through the second traction rope 25, and the block 24 will cancel the limit on the unloading plate 13, and then the unloading plate 13 will rotate downward around the top; then the second linear motor can drive the slide bar 17 to move upward back to the initial position; it should be noted that, Figure 7As shown, the second positioning plate 19 is arranged at one end near the slide bar 17 as a rotating structure (or an elastic structure). The second positioning plate 19 will not hinder the slide bar 17 from moving upward, but can hinder the slide bar 17 from moving downward. After the slide bar 17 drives the material frame 11 and the unloading plate 13 to move upward, the unloading plate 13 will gradually open, and then the hairy crabs on the unloading plate 13 will fall into the packaging box 14 in sequence along the opened unloading plate 13. After the hairy crabs fall into the packaging box 14, they will be neatly arranged. After the unloading plate 13 moves upward to release the first gear 28 and the rack rod 29, The rack rod 29 will drive the first gear 28 to drive the one-way bearing 27 and the unloading plate 13 to rotate, and the unloading plate 13 can be rotated to the top of the block 24 again, and the block 24 will limit the unloading plate 13 again; due to the setting of the one-way bearing 27, the first gear 28 will not get stuck when the unloading plate 13 moves downward; then when the unloading plate 13 is full of hairy crabs, the second linear motor drives the slide bar 17 to move downward again, and the slide bar 17 will move downward to contact the second positioning plate 19 at the bottom, and repeat the above-mentioned working process of placing hairy crabs, and the second row of hairy crabs will be placed on the unloading plate 13. The crabs can be piled up on top of the first row of hairy crabs, and the staff can prevent the hairy crabs from collapsing by placing partitions in the packaging box 14; this is repeated many times until the top second positioning plate 19 is extended, and the slide bar 17 moves downward to contact the top second positioning plate 19, and the hairy crabs are piled up at the top of the packaging box 14; at this time, the staff can manually pull the slide plate 31 outward, and the slide plate 31 will drive the second positioning plate 19 to move outward through the push rod 30 until the second positioning plate 19 is limited by the wedge-shaped limit block 21 again; then the first linear motor can be The driving support platform 15 drives the packaging box 14 to move backward a short distance, and the next time the unloading plate 13 unloads, it can be piled up next to the first row of hairy crabs; until the packaging box 14 is full of hairy crabs, the staff can then replace the packaging box 14; the present invention arranges the hairy crabs neatly when they are placed in the packaging box 14 through the arrangement of the packaging mechanism 4, the material frame 11, the unloading plate 13 and the matching driving components, and the staff does not need to sort the hairy crabs later, which can greatly improve the sorting and packaging efficiency of the hairy crabs and greatly reduce the possibility of damage to the hairy crabs.

[0038] As a further solution of the present invention, a soft material is provided on the inner wall of the material frame 11 .

[0039] During operation, by arranging a soft material on the inner wall of the material frame 11, it is possible to prevent the inner wall of the material frame 11 from expanding and causing damage when the hairy crab slides.

[0040] As a further solution of the present invention, a positioning rod 32 is fixedly connected to the top of the supporting platform 15 .
