Description

Technical Field

[0001] This invention relates to the field of aquatic product processing technology, and in particular to a shrimp posture adjustment device and adjustment method. Background Technology

[0002] In the seafood processing industry, shrimp, as a high-value product, has made automation and precision in its processing a core requirement for industrial upgrading. Currently, while automated equipment has gradually replaced manual labor in basic processes such as shrimp selection and cutting, effectively improving some production efficiency, existing processing equipment still suffers from three key pain points that severely restrict the industry's large-scale and high-quality development: On the one hand, adjusting the shrimp's posture relies on manual labor, highlighting the contradiction between efficiency and cost. Existing equipment lacks the ability to automatically correct the shrimp's posture, and shrimp are prone to abnormal postures such as tilting or inverting their heads and tails during transportation. Before subsequent processing, each shrimp needs to be manually straightened, making it difficult to improve overall production efficiency.

[0003] On the other hand, posture deviations lead to insufficient processing precision and significant raw material loss. Due to the lack of automated posture adjustment functions, such as in core processing steps like head cutting and back opening, disordered shrimp posture can easily result in accidental cutting of the shrimp body, directly causing raw material loss and significantly reducing the product processing qualification rate.

[0004] In addition, most shrimp screening equipment on the market currently uses visual recognition solutions. However, in aquatic product processing scenarios, factors such as the reflective surface of shrimp shells or water stains remaining on the surface of shrimp bodies can easily interfere with the visual recognition system, resulting in large fluctuations in screening accuracy and a high misjudgment rate.

[0005] Therefore, a shrimp posture adjustment device and method are proposed to solve the technical problems of low efficiency and high labor costs caused by the reliance on manual adjustment of shrimp bodies in existing shrimp processing equipment. Summary of the Invention

[0006] In view of this, the present invention proposes a shrimp posture adjustment device and adjustment method to solve the technical problems of low efficiency and high labor costs caused by the reliance on manual adjustment of shrimp bodies in existing shrimp processing equipment.

[0007] This invention proposes a shrimp posture adjustment device, comprising: The shrimp inlet component, conveying component, shrimp turning component, and shrimp outlet component are arranged sequentially along the shrimp conveying path. The conveying component has a rotating part, and the rotating part is provided with a plurality of shrimp-sorting holes, the inner contour of which is adapted to the outer contour of the shrimp body; The shrimp inlet component forms a shrimp inlet channel, in which shrimp bodies with their heads and tails facing the same direction are placed. The shrimp outlet side of the shrimp inlet channel is located on the movement path of the shrimp sorting hole and is used to transport the shrimp bodies to the shrimp sorting hole. The shrimp-turning component is disposed on the conveying component and located on the shrimp-out side of the rotating part, and is used to adjust the orientation of the shrimp's back to convey shrimp with consistent posture.

[0008] Based on the above technical solution, preferably, the conveying component includes: A rotating disk, a fixed frame, and a drive unit are sequentially arranged along the shrimp conveying path. The rotating disk is located at the output end of the drive unit and rotates relative to the fixed frame. The rotating disk is provided with a plurality of shrimp sorting holes. The shrimp inlet and shrimp outlet are respectively arranged on different sides of the fixed frame along the shrimp conveying path. The shrimp turning component is arranged on the fixed frame and located in the movement path of the plurality of shrimp sorting holes.

[0009] Based on the above technical solution, preferably, the fixing frame is provided with a shrimp turning trough; The shrimp-turning component includes a first pad and a second pad. The first pad and the second pad are spaced apart in the shrimp-turning groove along the length of the shrimp-handling hole. The distance between the first pad and the second pad is less than the length of the shrimp body, and the height of the first pad is not greater than half the width of the shrimp body.

[0010] Based on the above technical solution, preferably, the shrimp turning groove is rounded on the side near the shrimp outlet.

[0011] Based on the above technical solution, preferably, the depth of the shrimp turning trough is no greater than one-quarter of the width of the shrimp body.

[0012] Based on the above technical solution, preferably, the side of the shrimp turning trough that contacts the shrimp body is perpendicular to the direction of the shrimp body's movement.

[0013] Based on the above technical solution, preferably, the shrimp-turning component further includes a third pad and a fourth pad, which are disposed between the first pad and the second pad to adjust the distance between the first pad and the second pad.

[0014] Based on the above technical solution, preferably, the plurality of shrimp-cleaning holes move around the central circumference of the fixing frame, the first pad is located in the inner ring of the movement trajectory of the shrimp-cleaning holes, the second pad is located in the outer ring, and the height of the second pad is greater than the height of the first pad.

[0015] Based on the above technical solution, preferably, the fixing frame is provided with a shrimp outlet hole, which is located on the shrimp outlet side of the shrimp turning trough; The shrimp ejector has a receiving surface and a shrimp storage space. One end of the receiving surface is inclined and faces the shrimp ejection hole opening, while the other end of the receiving surface faces the shrimp storage space, which is used to guide shrimp with the same posture to slide into the shrimp storage space.

[0016] On the other hand, the present invention also provides a method for adjusting the posture of a shrimp, using the aforementioned shrimp posture adjustment device, comprising the following steps: Step S1: Place the shrimp to be processed, head and tail aligned, into the shrimp inlet channel; Step S2: The shrimp are passed through the shrimp inlet channel through several shrimp sorting holes in sequence, so that the individual shrimp fall into each shrimp sorting hole in sequence. Step S3: Move each shrimp hole to the shrimp turning groove, so that the head and tail ends of the shrimp body contact the first pad and the second pad respectively, so that the shrimp back naturally faces down under the action of gravity; Step S4: Move each shrimp hole out of the shrimp turning groove. The shrimp's back will contact the side wall of the shrimp turning groove. At this time, the shrimp will rotate 90 degrees along its own axial extension direction to make all the shrimp have the same posture. Step S5: Push several shrimp with the same posture into the shrimp storage space.

[0017] The shrimp posture adjustment device and method provided by this invention have the following advantages compared with the prior art: Under the action of the shrimp holes on the rotating part, all individual shrimp are made to pass through the shrimp turning component in sequence, and the shrimp posture is uniformly adjusted under the action of the shrimp turning component. The shrimp turning component adjusts the individual shrimp in sequence, completely replacing the manual shrimp placement operation, avoiding the interruption of the processing flow, greatly improving production efficiency and reducing labor costs. The drive unit drives the rotating disk to rotate smoothly and at a constant speed. When the shrimp sorting holes on the rotating disk move to the shrimp outlet side of the shrimp inlet channel, the shrimp pre-arranged in the shrimp inlet channel automatically fall into the shrimp sorting holes that match the shrimp's outer contour under their own gravity. Each shrimp sorting hole can only hold one shrimp, achieving precise single-shrimp sorting. As the rotating disk continues to rotate, the shrimp-carrying holes pass through the shrimp turning component in an orderly manner. Under the directional action of the shrimp turning component, the shrimp's posture is adjusted, and finally, the shrimp are directionally conveyed outward through the shrimp outlet, forming a continuous automated processing flow.

Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0027] The technical solution is explained below. Currently, most shrimp sorting equipment on the market uses visual recognition. However, in aquatic product processing scenarios, factors such as the reflective surface of shrimp shells or water stains on the shrimp's surface can easily interfere with visual recognition systems, leading to large fluctuations in sorting accuracy and a high false positive rate. Therefore, if... Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a shrimp posture adjustment device, comprising: The shrimp inlet component 1, the conveying component 2, the shrimp turning component 3, and the shrimp outlet component 4 are arranged sequentially along the shrimp conveying path. The conveying component 2 has a rotating part, and the rotating part is provided with a plurality of shrimp-rearing holes 201. The inner contour of the shrimp-rearing holes 201 is adapted to the outer contour of the shrimp body. The shrimp inlet 1 forms a shrimp inlet channel, and shrimp with their heads and tails facing the same direction are placed in the shrimp inlet channel. The shrimp outlet side of the shrimp inlet channel is located in the movement path of the shrimp sorting hole 201 and is used to transport the shrimp to the shrimp sorting hole 201. The shrimp-turning component 3 is mounted on the conveying component 2 and located on the shrimp-out side of the rotating part. It is used to adjust the orientation of the shrimp's back to ensure that the shrimp are conveyed in a consistent posture.

[0028] Under the action of the shrimp hole 201 on the rotating part, all individual shrimps pass through the shrimp turning component 3 in sequence, and the shrimp posture is uniformly adjusted under the action of the shrimp turning component 3. The shrimp turning component 3 adjusts the individual shrimps in sequence, completely replacing the manual shrimp placement operation, avoiding the interruption of the processing flow, greatly improving production efficiency and reducing labor costs.

[0029] like Figure 2 and Figure 3 As shown, in order to transport the shrimp body to the shrimp-turning component 3, the conveying component 2 includes: A rotating disk 21, a fixed frame 22, and a drive unit 23 are sequentially arranged along the shrimp conveying path. The rotating disk 21 is located at the output end of the drive unit 23 and rotates relative to the fixed frame 22. The rotating disk 21 is provided with a number of shrimp-sorting holes 201. The shrimp-infeeding component 1 and the shrimp-outfeeding component 4 are respectively arranged on different sides of the fixed frame 22 along the shrimp conveying path. The shrimp-turning component 3 is arranged on the fixed frame 22 and is located in the movement path of the number of shrimp-sorting holes 201.

[0030] The drive unit 23 drives the rotating disk 21 to rotate smoothly and at a constant speed. When the shrimp sorting holes 201 on the rotating disk 21 move to the shrimp outlet side of the shrimp inlet channel, the shrimp bodies pre-arranged in the shrimp inlet channel automatically fall into the shrimp sorting holes 201 that are adapted to the outer contour of the shrimp body under their own gravity. Each shrimp sorting hole 201 can only accommodate a single shrimp body, achieving precise single-shrimp sorting. As the rotating disk 21 continues to rotate, the shrimp sorting holes 201 carrying the shrimp bodies pass through the shrimp turning component 3 in an orderly manner. Under the directional action of the shrimp turning component 3, the shrimp body posture is adjusted, and finally, the shrimp bodies are directionally conveyed outward through the shrimp outlet component 4, forming a continuous automated processing flow.

[0031] Specifically, the length and width of the shrimp-cleaning hole 201 are described. The length of the shrimp-cleaning hole 201 in the radial extension direction of the rotating disk 21 is equal to the length of the shrimp being processed. The width of the shrimp-cleaning hole 201 is adapted to the width of the shrimp body, wherein the width of the shrimp body is the width from the shrimp belly to the shrimp back. The depth of the shrimp-cleaning hole 201 is preferably slightly greater than the thickness of the shrimp body. After the shrimp body falls into the shrimp-cleaning hole 201, the shrimp-feeding component 1 will no longer contact the shrimp body, which can ensure that the shrimp body rotates normally through the shrimp-feeding component 1.

[0032] like Figure 2 As shown, in order to accurately adjust the shrimp's posture, a shrimp turning groove 202 is provided on the fixing frame 22; The shrimp-turning component 3 includes a first pad 31 and a second pad 32. The first pad 31 and the second pad 32 are spaced apart in the shrimp-turning groove 202 along the length extension direction of the shrimp-handling hole 201. The distance between the first pad 31 and the second pad 32 is less than the length of the shrimp body, and the height of the first pad 31 is not greater than half the width of the shrimp body.

[0033] When the rotating disk 21 drives the shrimp-carrying hole 201 into the shrimp-turning trough 202, the two ends of the shrimp body will first contact the two pads. Under the action of the first pad 31 and the second pad 32, the middle of the shrimp body is unsupported. Since the shrimp body itself is spindle-shaped, the middle of the shrimp body has a large mass. Moreover, the shrimp body itself has a tendency to bend towards the ventral side. Under natural conditions, it is difficult to bend in the opposite direction. Therefore, when the head and tail are raised, the shrimp body will present a posture with its back facing down under the action of weight. Therefore, the shrimp body is designed with the height and spacing of the pads at both ends to ensure that all shrimp bodies are in a posture with their backs facing down. Finally, when the shrimp body moves to the edge of the shrimp-turning trough 202, the side wall of the shrimp-turning trough 202 will push the shrimp backs, and according to the rotation direction in the figure, make each shrimp body rotate 90 degrees clockwise to keep the posture of each shrimp body consistent, and the back of each shrimp body is facing the side opposite to the rotation direction. The shrimp-turning groove 202, together with the two pads, forms a purely mechanical posture adjustment structure. It can adjust the posture of only one shrimp at a time, ensuring strong consistency in posture adjustment and avoiding deviation or jamming. No additional power is required. The shrimp-turning structure design is simple and stable, reducing energy consumption and maintenance costs.

[0034] like Figure 3 and Figure 4 As shown, in order to protect the shrimp, the shrimp turning groove 202 is rounded on the side near the shrimp outlet 4.

[0035] When the shrimp is turned over by the shrimp turning groove 202 to turn its back towards the opposite direction, the shrimp turning groove 202 needs to come into direct contact with the shrimp body. In order to avoid damage to the shrimp body from contact and collision, the shrimp turning groove 202 is designed with rounded corners. This can minimize the impact damage to the shrimp body when it comes into contact with the shrimp body, giving the shrimp body an extra layer of protection and preventing damage.

[0036] More specifically, the sides of the first pad 21 and the second pad 32 that come into contact with the shrimp body are also rounded to prevent the shrimp body from being worn during the adjustment process.

[0037] More specifically, the side of the shrimp-turning groove 202 that contacts the shrimp body is perpendicular to the direction of the shrimp's movement. The sidewall of the shrimp-turning groove 202 used to change the shrimp's posture is perpendicular to the direction of the shrimp's movement, which ensures that the shrimp-turning groove 202 directly pushes the shrimp's back to flip over, thus ensuring stable adjustment of the shrimp's posture.

[0038] Since the width and length of the shrimp-handling hole 201 are adapted to the width and length of the shrimp body, for ease of production and processing, the width and length of the shrimp body can be directly understood as the width and length of the shrimp-handling hole 201. When the shrimp body falls into the shrimp-handling hole 201, it lies flat inside the shrimp-handling hole 201. The width of the shrimp-handling hole 201 is defined as d, and the length as l. The heights D1 and D2 of the first pad 31 and the second pad 32 are between 0.45d and 0.7d; the distance between the first pad 31 and the second pad 32 is between 0.5l and 0.625l. The heights of the first pad 31 and the second pad 32, as well as the distance between the first pad 31 and the second pad 32, are limited here to ensure that the shrimp body can stably change to a shrimp-back-down position in the shrimp-turning tank 202.

[0039] like Figure 4 As shown, in order to ensure that the shrimp's posture is stably adjusted, the depth of the shrimp turning groove 202 is no more than one-quarter of the width of the shrimp's body, which is the width of the shrimp's body, i.e., the width of the shrimp's body.

[0040] The depth of the shrimp turning groove 202 determines the contact position between the shrimp's back and the side wall of the shrimp turning groove 202. If the shrimp turning groove 202 is too deep, it will cause the shrimp body to bend too much and the shrimp body to swing too much during the adjustment process, which will bring instability to the shrimp body posture adjustment process. Limiting the depth of the shrimp turning groove 202 here can ensure that the shrimp body posture swings less during the adjustment process and ensure that the shrimp body posture changes stably.

[0041] like Figure 5 As shown, in order to adapt the shrimp-turning structure to shrimp of different sizes, the shrimp-turning component 3 also includes a third pad 33 and a fourth pad 34. The third pad 33 and the fourth pad 34 are disposed between the first pad 31 and the second pad 32 to adjust the distance between the first pad 31 and the second pad 32.

[0042] By attaching the third pad 33 and the fourth pad 34 between the first pad 31 and the second pad 32, the distance between them can be changed, allowing the shrimp-flipping structure to adapt to shrimp of different sizes and improving the adaptability of the device. When changing the distance between the first pad 31 and the second pad 32, the third pad 33 and the fourth pad 34 can also change the height of the first pad 31 and the height of the second pad 32 to further ensure that the shrimp-flipping structure can adapt to shrimp of different sizes.

[0043] like Figure 4 As shown, several shrimp-cleaning holes 201 move around the center circle of the fixed frame 22. The first pad 31 is located in the inner ring of the movement trajectory of the shrimp-cleaning holes 201, and the second pad 32 is located in the outer ring. The height of the second pad 32 is greater than the height of the first pad 31.

[0044] The rotating disk 21 rotates around its center on the fixed frame 22. Several shrimp-feeding holes 201 are evenly spaced and circumferentially distributed on the rotating disk 21. When the rotating disk 21 rotates, the shrimp-feeding holes 201 pass through the shrimp-feeding channel in sequence. The shrimp in the shrimp-feeding holes 201 rotate with the rotating disk 21 relative to the fixed frame 22. The height of the second pad 32 is greater than the height of the first pad 31. The height of the second pad 32 can prevent the shrimp from being subjected to excessive centrifugal force during rotation and prevent the shrimp from being thrown out during rotation. The height difference between the second pad 32 and the first pad 31 can be in the range of 0.05d to 0.1d.

[0045] More specifically, when the shrimp body is located within the shrimp-cleaning hole 201, the heads of several shrimp bodies are close to the center of the rotating disk 21, while the tails are far away from the center of the rotating disk 21. The shrimp heads are close to the center of motion, preventing them from getting stuck in the gap between the rotating disk 21 and the fixed frame 22, thus improving the stability of the conveying. After fixing the radial posture of the shrimp body, the shrimp-cleaning hole 201 only needs to be adapted to the shape and outline of the shrimp, without the need for additional design of limiting structures to constrain the direction of the head and tail, which simplifies the processing difficulty and cost of the shrimp-cleaning hole.

[0046] It is worth mentioning that when the shrimp's head is close to the center of the rotating disk 21, the length of the first pad 31 extending radially along the rotating disk 21 is less than 0.375l, so that the shrimp's head can contact the edge of the first pad 31.

[0047] like Figure 4 As shown, in order to ensure stable output of the shrimp after posture adjustment, the fixing frame 22 is provided with a shrimp outlet 203, which is located on the shrimp outlet side of the shrimp turning groove 202. The shrimp ejector 4 has a receiving surface 401 and a shrimp storage space 402. One end of the receiving surface 401 is inclined and faces the opening of the shrimp ejection hole 203. The other end of the receiving surface 401 faces the shrimp storage space 402, which is used to guide shrimp with the same posture to slide into the shrimp storage space 402.

[0048] To ensure stable output of shrimp after posture adjustment, a shrimp outlet 203 is provided on the fixing frame 22. After the shrimp posture is adjusted, it will enter the shrimp outlet 203 under the push of the shrimp adjustment hole 201, and be guided to the shrimp storage space 402 by the inclined receiving surface 401. When the shrimp that has completed posture correction detaches from the shrimp turning trough 202, it will fall smoothly onto the inclined receiving surface and slide steadily into the shrimp storage space 402 by gravity. The entire process can achieve orderly collection without additional power.

[0049] Specifically, the width of the shrimp storage space 402 is adapted to the thickness of the shrimp body, so that several shrimp bodies with the same posture can be stacked vertically, which can effectively save the space for stacking shrimp bodies.

[0050] Specifically, under the action of the shrimp outlet 203 and the inclined receiving surface 401, the shrimp body after its posture adjustment is transported by gravity, without the need for additional drive components. This simplifies the structure, reduces energy consumption, and avoids the impact of additional drive components on the shrimp body's posture.

[0051] like Figure 2 and Figure 3 As shown, the shrimp inlet 1 includes a shrimp inlet tube 11 and a support member 12. The shrimp inlet tube 11 forms a shrimp inlet channel, and the support member 12 is bent at a right angle. One end of the support member 12 is set on the side of the fixed frame 22, and the other end of the support member 12 supports the shrimp inlet tube 11 and holds the shrimp inlet tube 11 above the rotating disk 21, so that the shrimp inlet tube 11 can maintain a gap with the rotating disk 21. When the shrimp passes through the shrimp inlet tube 11 through the shrimp sorting hole 201, the shrimp body falls into the shrimp sorting hole 201 under the action of gravity.

[0052] It is worth mentioning that the opening at the shrimp outlet end of the shrimp inlet channel is set along the radial extension direction of the rotating disk 21. That is, the shrimp will only fall into the shrimp outlet 201 when the shrimp sorting hole 201 on the rotating disk 21 rotates to coincide with the shrimp outlet opening of the shrimp inlet channel. In this way, it can prevent shrimp from accidentally falling into the shrimp sorting hole 201 and ensure that each shrimp sorting hole 201 transports only one shrimp at a time.

[0053] On the other hand, the present invention also provides a method for adjusting the posture of a shrimp, using the aforementioned shrimp posture adjustment device, comprising the following steps: Step S1: Place the shrimp to be processed with their heads and tails aligned in the shrimp inlet channel, which stores the shrimp. Step S2: By rotating the disk 21, the shrimp sorting holes 201 are sequentially brought to the predetermined position of the shrimp inlet 1 and pass through the discharge end of the shrimp inlet channel, so that the individual shrimp bodies fall into each shrimp sorting hole 201 in sequence. Step S3: By rotating the disk 21, each shrimp hole 201 is moved to the shrimp turning groove 202, and the head and tail ends of the shrimp body are in contact with the first pad 31 and the second pad 32 respectively, so that the shrimp back is naturally facing down under the action of gravity. Step S4: By rotating the disk 21, each shrimp hole 201 is moved out of the shrimp turning groove 202. The shrimp back will contact the side wall of the shrimp turning groove 202. At this time, the shrimp body will rotate 90 degrees clockwise along its own axial extension direction. The direction of the shrimp back will be opposite to the direction of the shrimp body's movement, so that all shrimp bodies have the same posture. Step S5: Push several shrimp with the same posture into the shrimp storage space 402.

[0054] This shrimp posture adjustment method is precise and efficient. It follows a step-by-step sequence: head and tail orientation is placed into the shrimp inlet channel, shrimp is sorted individually through the shrimp sorting hole 201, the shrimp back is fully supported by pads, and the shrimp back is flipped over by the side wall of the shrimp flipping trough 202. First, the direction of the shrimp's head and tail is constrained. Then, through the synergistic effect of the pads and side wall in the shrimp flipping trough, the shrimp are finally uniformly placed in the shrimp storage space 402 without human intervention, completely replacing manual shrimp placement and posture correction.

[0055] In addition, this shrimp body adjustment method has a low damage rate, ensuring the quality of raw materials. The shrimp body turning process mainly relies on gravity and mechanical flexible contact to achieve posture adjustment without hard squeezing or forced turning. It is also combined with the adaptability of the shrimp hole 201 to the shrimp body contour to reduce the collision of shrimp bodies during screening and turning, ensure the integrity of shrimp bodies, and reduce the raw material loss rate.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The first pad (31) and the second pad (32) are spaced apart in the shrimp-turning groove (202) along the length extension direction of the shrimp-handling hole (201). The distance between the first pad (31) and the second pad (32) is less than the length of the shrimp body. The height of the first pad (31) is not greater than half the width of the shrimp body. The shrimp turning groove (202) has a rounded corner on the side near the shrimp outlet (4).

2. The shrimp posture adjustment device as described in claim 1, characterized in that, The depth of the shrimp turning groove (202) is no greater than one-quarter of the width of the shrimp body.

3. The shrimp posture adjustment device as described in claim 1, characterized in that, The side of the shrimp turning trough (202) that contacts the shrimp body is perpendicular to the direction of the shrimp body's movement.

4. The shrimp posture adjustment device as described in claim 1, characterized in that, The shrimp-turning component (3) also includes a third pad (33) and a fourth pad (34), which are disposed between the first pad (31) and the second pad (32) to adjust the distance between the first pad (31) and the second pad (32).

5. The shrimp posture adjustment device as described in claim 1, characterized in that, The plurality of shrimp-cleaning holes (201) move around the center circumference of the fixing frame (22), the first pad (31) is located in the inner ring of the movement trajectory of the shrimp-cleaning holes (201), the second pad (32) is located in the outer ring, and the height of the second pad (32) is greater than the height of the first pad (31).

6. The shrimp posture adjustment device as described in claim 1, characterized in that, The fixing frame (22) is provided with a shrimp outlet hole (203), which is located on the shrimp outlet side of the shrimp turning groove (202); The shrimp ejector (4) has a receiving surface (401) and a shrimp storage space (402). One end of the receiving surface (401) is inclined and faces the opening of the shrimp ejector hole (203). The other end of the receiving surface (401) faces the shrimp storage space (402) to guide shrimp with the same posture to slide into the shrimp storage space (402).

7. A method for adjusting the posture of shrimp, characterized in that, Using the shrimp posture adjustment device as described in claim 6 includes the following steps: Step S1: Place the shrimp to be processed, head and tail aligned, into the shrimp inlet channel; Step S2: Through a number of shrimp sorting holes (201), the shrimp pass through the discharge end of the shrimp inlet channel in sequence, so that the individual shrimp fall into each shrimp sorting hole (201) in sequence; Step S3: Move each shrimp hole (201) to the shrimp turning groove (202), so that the head and tail ends of the shrimp body contact the first pad (31) and the second pad (32) respectively, so that the shrimp back naturally faces downward under the action of gravity; Step S4: Move each shrimp hole (201) out of the shrimp turning groove (202). The back of the shrimp body will contact the side wall of the shrimp turning groove (202). At this time, the shrimp body will rotate 90 degrees along its own axial extension direction, so that all the shrimp bodies have the same posture. Step S5: Push several shrimp with the same posture into the shrimp storage space (402).
