Description

Technical Field

[0001] This utility model relates to the field of oyster separation technology, and in particular to a highly stable ultra-high pressure oyster separation device. Background Technology

[0002] Oysters are bivalve mollusks with two unequal shells connected by ligaments and adductor muscles. The usable parts of an oyster are divided into oyster meat and oyster shell. Oyster meat has edible and medicinal value, while oyster shell can be used to make oyster shell soil conditioner, which can significantly increase vegetable yield, reduce heavy metal content, and increase pH value. In order to make full use of oyster meat and oyster shell, the oyster meat and oyster shell need to be separated after the mature oysters are harvested.

[0003] Previously, oyster separation was usually done manually. However, a patent document with publication number CN 118614532 A discloses an ultra-high pressure separation device. Technicians place the oysters into the container of the ultra-high pressure device, and use the pressure evenly distributed inside the container to automatically separate the oyster meat from the shell, thus achieving automatic oyster separation. Then, a robotic arm removes the container from the container frame and dumps the oysters.

[0004] However, in actual use, technicians found that when using the robotic arm for loading and unloading, due to mechanical errors, the angle and position of the returned container slightly changed. After long-term production, this caused deviations in the air guiding structure, making it impossible to apply pressure and disrupting normal production. Simultaneously, because there is a gap between the container's sidewall and the container frame, when the container shifts, the pressurizing and sealing mechanism depresses, causing the container to tilt and further exacerbating the shift. Manual adjustment at this point requires significant time and manpower, severely impacting production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a highly stable ultra-high pressure oyster separation device, overcoming the problem of insufficient stability of existing ultra-high pressure oyster separation pressure devices, which leads to low production efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a highly stable ultra-high pressure oyster separation device, including a receiving frame set on a displacement mechanism, a receiving cylinder for receiving oysters movably installed inside the receiving frame, an upper fitting structure at the top of the receiving cylinder, a gantry frame at the end of the displacement mechanism, a pressurization sealing mechanism and an air guiding structure on the displacement mechanism, and a robotic arm in the feeding area of ​​the displacement mechanism, including:

[0007] The guide structure includes a guide arc plate and a slider. The guide arc plate is disposed on the inner surface of the accommodating frame. There are at least two guide arc plates. The gap between the guide arc plates forms a guide groove. The slider is disposed on the outer surface of the accommodating cylinder. The guide groove is disposed at least corresponding to the air inlet of the accommodating cylinder.

[0008] The rotating structure surrounds the outer surface of the receiving cylinder and is located in the part of the receiving cylinder that does not extend into the receiving frame. The rotating structure can rotate relative to the receiving cylinder. When picking up or placing the receiving cylinder, the robotic arm clamps the rotating structure and lifts the receiving cylinder. The slider slides along the guide groove, and the outer surface of the receiving cylinder abuts against the inner surface of the guide arc plate.

[0009] In one embodiment, the rotating structure includes a fixed ring seat, a clamping collar, and a rotating rod. The fixed ring seat is disposed on the outer surface of the accommodating cylinder, and there are two fixed ring seats. The clamping collar is disposed between the fixed ring seats. The rotating rod is distributed vertically and disposed between the inner surface of the clamping collar and the outer surface of the accommodating cylinder. The rotating rod is hinged to the clamping collar.

[0010] In one embodiment, a ball bearing is provided between the clamping collar and the fixed ring seat, and the ball bearing is provided at least at the top of the clamping collar.

[0011] In one embodiment, the fixed ring seat includes a limiting part and a connecting part. The connecting part is distributed in the horizontal direction and fixedly connected to the accommodating cylinder. The limiting part extends vertically from the end of the connecting part away from the accommodating cylinder. The limiting part and the connecting part together form an L-shaped ring structure. The two fixed ring seats together form a T-shaped rotating cavity. The clamping collar is disposed in the rotating cavity and is rotatably connected to the connecting part through ball bearings.

[0012] In one embodiment, the clamping collar includes a clamping ring portion and a rotating ring portion. The clamping ring portion is disposed outside the rotating ring portion, and there is a rotational gap between the inner surface of the rotating ring portion and the outer surface of the accommodating cylinder. The rotating ring portion is provided with a rotating groove on the side near the accommodating cylinder, and a rotating rod is hinged in the rotating groove and abuts against the outer surface of the accommodating cylinder.

[0013] In one embodiment, the outer surface of the clamping ring is flush with the outer surface of the limiting portion.

[0014] In one embodiment, the bottom of the fixing ring seat is provided with a tapered arc plate, which extends obliquely from the bottom of the fixing ring seat away from the receiving cylinder, and the maximum diameter of the tapered arc plate is greater than the outer diameter of the receiving frame.

[0015] In one embodiment, the bottom of the fixed ring seat is provided with a movable groove, the conical arc plate is sleeved on the movable groove, the conical arc plate slides up and down along the movable groove, and an adjusting spring is provided between the top of the movable groove and the conical arc plate.

[0016] In one embodiment, the corner of the guide arc plate is provided with a guide arc, which extends in an arc shape from the side wall of the guide arc plate to the top of the guide arc plate and moves away from the adjacent guide arc plate. The adjacent guide arc makes the guide groove form a flared section.

[0017] In one embodiment, the slider includes a rectangular portion and a semicircular portion, with the semicircular portion located at the bottom of the rectangular portion.

[0018] The beneficial effects of this invention are as follows: The rotating structure of the highly stable ultra-high pressure oyster shell separator provided by this invention allows the container to rotate relative to the robotic arm without affecting the gripping effect of the robotic arm. This allows the operator to adjust the relative angle between the container and the container frame. When the robotic arm places the container, the slider of the container slides along the guide groove. Upon placement, the angle alignment between the container and the container frame is automatically completed, ensuring the alignment of the air inlet and the air guiding structure. This guarantees that ultra-high pressure gas can be normally introduced into the container, ensuring production stability. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Please refer to Figures 1 to 5 A highly stable ultra-high pressure oyster separation device includes a receiving frame 1 set on a displacement mechanism, a receiving cylinder 2 for receiving oysters is movably installed in the receiving frame 1, the top of the receiving cylinder 2 is provided with an upper fitting structure, the end of the displacement mechanism is provided with a gantry frame, the displacement mechanism is provided with a pressurization sealing mechanism and an air guiding structure, and the feeding area of ​​the displacement mechanism is provided with a robotic arm.

[0030] The highly stable ultra-high pressure oyster shell separation equipment also includes a guide structure 3 and a rotating structure 4. The guide structure 3 includes a guide arc plate 31 and a slider 32. The guide arc plate 31 is disposed on the inner surface of the receiving frame 1, and at least two guide arc plates 31 are provided. The gap between the guide arc plates 31 forms a guide groove 311. The slider 32 is disposed on the outer surface of the receiving cylinder 2, and the guide groove 311 corresponds at least to the air inlet of the receiving cylinder 2. That is, the guide arc plate 31 is attached to the inner surface of the receiving frame 1, filling the gap between the receiving frame 1 and the receiving cylinder 2. The gap between the guide arc plates 31 forms the guide groove 311, allowing the air inlet of the receiving cylinder 2 and the slider 32 to slide along the guide groove 311, preventing the guide arc plate 31 from interfering with the connection between the air inlet and the air guiding structure, thereby ensuring normal production. Specifically, the slider 32 is located at least above or below the air inlet. Furthermore, after the guide arc plate 31 is set, the gap between the receiving frame 1 and the receiving cylinder 2 is eliminated, ensuring accurate positioning while making the receiving frame 1 and the receiving cylinder 2 form a whole during displacement. This can avoid the shaking and displacement of the receiving cylinder 2 caused by inertia during braking, further ensuring the overall accuracy and stability of the device.

[0031] The rotating structure 4 surrounds the outer surface of the receiving cylinder 2 and is located on the portion of the receiving cylinder 2 that does not extend into the receiving frame 1. The rotating structure 4 can rotate relative to the receiving cylinder 2. When the receiving cylinder 2 is picked up or placed, the robotic arm grips the rotating structure 4 and lifts the receiving cylinder 2. The slider 32 slides along the guide groove 311, and the outer surface of the receiving cylinder 2 abuts against the inner surface of the guide arc plate 31. The rotating structure 4 allows the receiving cylinder 2 to rotate relative to the robotic arm when it is placed. During the placement process, when the slider 32 is guided by the guide groove 311, the slider 32 causes the receiving cylinder 2 to be subjected to a tangential force, thereby causing it to rotate. This can prevent the receiving cylinder 2 from rotating.

[0032] Understandably, the rotating structure 4 of the highly stable ultra-high pressure oyster separator provided by this invention allows the containing cylinder 2 to rotate relative to the robotic arm without affecting the gripping effect of the robotic arm, enabling the adjustment of the relative angle between the containing cylinder 2 and the containing frame 1. When the robotic arm places the containing cylinder 2, the slider 32 of the containing cylinder 2 slides along the guide groove, automatically aligning the angle between the containing cylinder 2 and the containing frame 1, thereby aligning the air inlet and the air guiding structure and ensuring stability during long-term production.

[0033] Specifically, the displacement mechanism includes two tracks connected by a translation trolley. A cage frame is mounted on the translation trolley, and a receiving frame 1 is locked onto the cage frame. A receiving cylinder 2 for holding oysters is movably installed within the receiving frame 1. An upper fitting structure has an annular groove at the top of the receiving cylinder 2. This upper fitting structure includes a lower fixed hopper that engages within the annular groove. An arc-shaped feeding hopper is connected to the top of the lower fixed hopper, and an elastic ring plate is connected to the top of the arc-shaped feeding hopper. Oysters are guided into the receiving cylinder 2 by the elastic ring plate and the arc-shaped feeding hopper. A pressure sealing mechanism includes a gantry frame mounted on the two tracks. This pressure sealing mechanism includes a pressure applying structure mounted on the gantry frame. A pressure plate is fixed to the bottom of the pressure applying structure. An inner pressure seat corresponding to the shape of an arc-shaped hopper is provided, and an inner containing bag is provided on the inner side of the inner pressure seat. Several outer clamping structures are provided at intervals on the outer side of the inner pressure seat. After the pressure applying structure applies pressure to the lower pressure plate, the inner pressure seat of the lower pressure plate applies pressure to the inner side of the arc-shaped hopper, while the outer clamping structures push inward and apply pressure to the outer side of the arc-shaped hopper. An air guiding structure is provided with an air inlet on the outer side of the accommodating cylinder 2. The air guiding structure includes a connecting pipe located on the inner side of the gantry frame. The connecting pipe is connected to the air inlet through a driving component. The inner pressure seat is a frustum-shaped structure with an opening facing downward. The inner side of the inner pressure seat is hollow, and the containing bag is located on the inner side of the inner pressure seat. After the inner pressure seat is pressed down, the outer wall is tightly attached to the inner wall of the arc-shaped hopper. The external clamping structure includes several external support push rods fixed below the lower pressure plate. An arc-shaped inclined pressure plate is connected to the side of each external support push rod closest to the inner pressure seat. Adjacent arc-shaped inclined pressure plates are fitted together, and the arc-shaped inclined pressure plates are fitted against the outer wall of the arc-shaped hopper. Specific schemes for the displacement mechanism, upper fitting structure, gantry frame, pressurization and sealing mechanism, and air guiding structure in the ultra-high pressure oyster shell separation equipment are described in CN118614532 A and will not be discussed in detail here.

[0034] Preferably, the outer surface of the rotating structure 4 is provided with a clamping ring to facilitate the gripping and placement by the robotic arm.

[0035] In one embodiment, the rotating structure 4 includes a fixed ring seat 41, a clamping collar 42, and a rotating rod 43. Two fixed ring seats 41 are disposed on the outer surface of the accommodating cylinder 2, and the clamping collar 42 is disposed between the fixed ring seats 41. The rotating rod 43 is distributed vertically and disposed between the inner surface of the clamping collar 42 and the outer surface of the accommodating cylinder 2, and is hinged to the clamping collar 42. That is, the clamping collar 42 abuts against the accommodating cylinder 2 through the hinged rotating rod 43. When the accommodating cylinder 2 rotates, the rotating rod 43 rotates synchronously, while the clamping collar 42 is clamped and does not rotate. The fixed ring seat 41 restricts the position of the clamping collar 42, allowing the robotic arm to lift or place the accommodating cylinder 2 after clamping the clamping collar 42. Specifically, the fixed ring seat 41 is welded to the surface of the accommodating cylinder 2.

[0036] In one embodiment, a ball bearing 44 is provided between the clamping collar 42 and the fixed ring seat 41, and the ball bearing 44 is at least located on the top of the clamping collar 42. Specifically, after the ball bearing 44 is provided, the relative rotation between the clamping collar 42 and the accommodating cylinder 2 is smoother, effectively avoiding the friction between the clamping collar 42 and the fixed ring seat 41 from interfering with the guiding engagement of the guide groove 311 and the slider 32.

[0037] In one embodiment, the fixed ring seat 41 includes a limiting part 411 and a connecting part 412. The connecting part 412 is distributed horizontally and fixedly connected to the accommodating cylinder 2. The limiting part 411 extends vertically from the end of the connecting part 412 away from the accommodating cylinder 2. The limiting part 411 and the connecting part 412 together form an L-shaped ring structure. The two fixed ring seats 41 together form a T-shaped rotating cavity. The clamping collar 42 is disposed in the rotating cavity and is rotatably connected to the connecting part 412 through ball bearings 44. This arrangement ensures that the clamping collar 42 will not come out, guaranteeing the safety and stability of the production process.

[0038] In one embodiment, the clamping collar 42 includes a clamping ring portion 421 and a rotating ring portion 422. The clamping ring portion 421 is disposed outside the rotating ring portion 422, and a rotational gap 423 exists between the inner surface of the rotating ring portion 422 and the outer surface of the accommodating cylinder 2. The rotating ring portion 422 has a rotating groove on the side near the accommodating cylinder 2, and a rotating rod 43 is hinged in the rotating groove, abutting against the outer surface of the accommodating cylinder 2. This arrangement prevents the clamping collar 42 from contacting the accommodating cylinder 2, reducing friction and making the rotation of the accommodating cylinder 2 smoother, thereby ensuring the guiding function of the guide structure 3.

[0039] In one embodiment, the outer surface of the clamping ring 421 is flush with the outer surface of the limiting part 411. This arrangement prevents oyster shells from entering the rotating cavity, ensuring smooth rotation of the clamping ring 421 and the housing 2, thereby ensuring production stability and improving the overall service life of the device.

[0040] In one embodiment, a conical arc plate 45 is provided at the bottom of the fixing ring seat 41. The conical arc plate 45 extends obliquely from the bottom of the fixing ring seat 41 away from the receiving cylinder 2, and the maximum diameter of the conical arc plate 45 is larger than the outer diameter of the receiving frame 1. Specifically, the conical arc plate 45 is frustoconical in shape and is fitted onto the bottom of the fixing ring seat 41, forming an "eaves" to shield the receiving frame 1. After the conical arc plate 45 is set, it covers the receiving frame 1, the receiving cylinder 2, and the gap between them, preventing oyster shell fragments from entering the receiving frame 1 and the guide groove 311, preventing oyster shell fragments from affecting the alignment of the receiving frame 1 and the receiving cylinder 2, reducing the number of times the receiving frame 1 needs to be cleaned, and improving the continuity and stability of production. Preferably, the lowest point of the conical arc plate 45 is lower than the highest point of the receiving frame 1, which ensures the shielding effect of the conical arc plate 45.

[0041] In one embodiment, the bottom of the fixed ring seat 41 is provided with a movable groove 413, and the conical arc plate 45 is sleeved on the movable groove 413. The conical arc plate 45 slides up and down along the movable groove 413, and an adjusting spring 46 is provided between the top of the movable groove 413 and the conical arc plate 45. With this configuration, when the conical arc plate 45 contacts the receiving frame 1 during placement, it can slide up and down, ensuring the blocking effect while avoiding damage to the conical arc plate 45.

[0042] In one embodiment, the corners of the guide arc plate 31 are provided with guide arcs 312. The guide arcs 312 extend in an arc shape from the sidewall of the guide arc plate 31 to the top of the guide arc plate 31 and away from the adjacent guide arc plates 31. The adjacent guide arcs 312 make the guide groove 311 form a flared section. That is, the two corners of the top of the guide arc plate 31 are provided with guide arcs 312. The guide arcs 312 make the guide groove 311 form a semi-funnel shape that gradually narrows downwards. In this way, when the slider 32 deviates, it can guide the slider 32 to the correct angle, ensuring the smoothness of the guidance and preventing the slider 32 from getting stuck after it comes into contact with the guide arc plate 31.

[0043] In one embodiment, the slider 32 includes a rectangular portion 321 and a semi-circular portion 322, with the semi-circular portion 322 located at the bottom of the rectangular portion 321. This arrangement allows the slider 32 to be smoothly guided into the guide groove 311, ensuring proper alignment.

[0044] Please refer to Figures 1 to 5 Embodiment 1 of this utility model is: a highly stable ultra-high pressure oyster separation device, including a receiving frame 1 set on a displacement mechanism, a receiving cylinder 2 for receiving oysters movably installed inside the receiving frame 1, an upper fitting structure at the top of the receiving cylinder 2, a gantry frame at the end of the displacement mechanism, a pressurization sealing mechanism and an air guiding structure on the displacement mechanism, and a robotic arm in the feeding area of ​​the displacement mechanism, including:

[0045] The guide structure 3 includes a guide arc plate 31 and a slider 32. The guide arc plate 31 is disposed on the inner surface of the accommodating frame 1. There are 4 guide arc plates 31. The gap between the guide arc plates 31 forms 4 guide grooves 311. The slider 32 is disposed on the outer surface of the accommodating cylinder 2. One guide groove 311 is disposed corresponding to the air inlet of the accommodating cylinder 2.

[0046] The rotating structure 4 surrounds the outer surface of the accommodating cylinder 2 and is located in the middle of the accommodating cylinder 2. The rotating structure 4 is higher than the accommodating frame 1. The rotating structure 4 can rotate relative to the accommodating cylinder 2. The rotating structure 4 includes a fixed ring seat 41, a clamping collar 42, and a rotating rod 43. The fixed ring seat 41 is disposed on the outer surface of the accommodating cylinder 2, and there are two fixed ring seats 41. The clamping collar 42 is disposed between the fixed ring seats 41. The rotating rod 43 is distributed vertically and disposed between the inner surface of the clamping collar 42 and the outer surface of the accommodating cylinder 2. The rotating rod 43 is hinged to the clamping collar 42.

[0047] The fixed ring seat 41 includes a limiting part 411 and a connecting part 412. The connecting part 412 is distributed in the horizontal direction and is fixedly connected to the accommodating cylinder 2. The limiting part 411 extends vertically from the end of the connecting part 412 away from the accommodating cylinder 2. The limiting part 411 and the connecting part 412 together form an L-shaped ring structure. The two fixed ring seats 41 together form a T-shaped rotating cavity. The clamping sleeve 42 is disposed in the rotating cavity. The clamping sleeve 42 is rotatably connected to the connecting parts 412 on both sides through balls 44. The clamping collar 42 includes a clamping ring portion 421 and a rotating ring portion 422. The clamping ring portion 421 is disposed outside the rotating ring portion 422. There is a rotation gap 423 between the inner surface of the rotating ring portion 422 and the outer surface of the accommodating cylinder 2. The rotating ring portion 422 is provided with a rotating groove on the side near the accommodating cylinder 2. The rotating rod 43 is hinged in the rotating groove and abuts against the outer surface of the accommodating cylinder 2. Eight rotating rods 43 are arranged at intervals.

[0048] When picking up or placing the container cylinder 2, the robotic arm grips the rotating structure 4 to lift the container cylinder 2, the slider 32 slides along the guide groove 311, and the outer surface of the container cylinder 2 abuts against the inner surface of the guide arc plate 31.

[0049] In this embodiment, the bottom of the fixing ring seat 41 is provided with a conical arc plate 45. The conical arc plate 45 extends obliquely from the bottom of the fixing ring seat 41 in a direction away from the receiving cylinder 2. The maximum diameter of the conical arc plate 45 is greater than the outer diameter of the receiving frame 1.

[0050] In this embodiment, the corner of the guide arc plate 31 is provided with a guide arc 312. The guide arc 312 extends in an arc shape from the side wall of the guide arc plate 31 to the top of the guide arc plate 31 and moves away from the adjacent guide arc plate 31. The adjacent guide arc 312 makes the guide groove 311 form a flared section.

[0051] The working principle of this utility model is as follows: At the unloading position, the robotic arm clamps and lifts the clamping collar 42, causing the clamping collar 42 to abut against the fixed ring seat 41, thereby driving the entire accommodating cylinder 2 to rise. After the unloading is completed, the robotic arm resets the clamping collar 42 and gradually lowers it. During the descent, if the angle of the accommodating cylinder 2 deviates, the slider 32 contacts the guide arc 312 of the guide groove 311 and is guided to the correct position during the descent. At this time, the accommodating cylinder 2 is subjected to a tangential force and rotates relative to the clamping collar 42, while the clamping collar 42 is held still by the robotic arm. After placement and alignment, the loading operation is performed. The oysters are unloaded into the accommodating cylinder 2, and the conical arc plate 45 prevents oyster shell fragments from entering the accommodating frame 1 and the guide groove 311, thus completing the loading. After loading, the accommodating cylinder 2 is conveyed by the moving mechanism for pressurized separation, and then the unloading and loading processes are repeated.
