Description

Technical Field

[0001] This invention belongs to the field of shelling device technology, and particularly relates to a shelling device. Background Technology

[0002] As people's living standards improve, crayfish have become increasingly popular due to their delicious taste. However, because crayfish shells are hard, with sharp spines on their heads that can easily prick the hands, and the outer skin on their abdomens being very tough, the shells are not easy to peel off. Most diners peel them by hand, but this is easy to injure and laborious, so many crayfish peeling tools have emerged on the market.

[0003] Currently, shrimp peeling tools are generally scissor-like. For example, utility model application CN201720427694.6 discloses a shrimp peeler with a splash guard, which consists of an upper handle, a lower handle, and a splash guard. The upper handle has an upper claw head, and the lower handle has a lower claw head. However, this type of peeler requires inserting the upper and lower claw heads, which are attached together, into the shrimp's body, making the operation cumbersome and prone to causing inconvenience. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0035] In one embodiment of the present invention, such as Figure 1 As shown, a sheller is provided, including a base 100 and a top cover 200, wherein the top cover 200 is rotatably connected to the base 100.

[0036] The peeler also includes an elastic placement member 300, a cutting member 400, and a squeezing member 500. The elastic placement member 300 is disposed on the base 100 and is used to hold whole shrimp. The cutting member 400 is installed on the lower end face of the upper cover 200. The squeezing member 500 is installed on the lower end face of the upper cover 200 and is located outside the cutting member 400. When the upper cover 200 is pressed down, the cutting member 400 gradually cuts and separates the shrimp head from the shrimp tail, and the squeezing member 500 gradually squeezes the shrimp tail and squeezes the shrimp meat out of the shrimp shell.

[0037] When using the sheller described in this invention, the whole shrimp is first placed on the elastic placement member 300, then the upper cover 200 is flipped so that it faces the base 100, and the upper cover 200 is continuously pressed down. During the pressing process, the cutting member 400 gradually comes into contact with the whole shrimp, and separates the shrimp head from the shrimp tail as it is pressed down. The separated shrimp head falls off naturally, while the squeezing member 500 gradually comes into contact with the shrimp tail during the pressing process, and then squeezes from the tail end toward the head of the shrimp tail until the shrimp meat is squeezed out of the shrimp shell. This achieves the goal of first cutting the shrimp head, then squeezing the shrimp shell, and finally squeezing out the shrimp meat. After the shrimp meat is squeezed out, the elastic placement member 300 resets and pops out the shrimp shell. The whole operation process is simple, not easy to hurt hands, convenient and quick to use, and greatly meets the user's needs.

[0038] In another embodiment of the present invention, in order to ensure that the whole shrimp is stable on the elastic placement member 300 and does not fall off after being placed on the elastic placement member 300, a protrusion (not shown) can be provided on the elastic placement member 300. After the whole shrimp is placed, the protrusion penetrates the shrimp shell to stably fix the shrimp. The protrusion can be a tooth or other structure capable of fixing the whole shrimp.

[0039] In another embodiment of the invention, such as Figures 1-2As shown, the upper cover 200 includes a rotating connector 211 and a cover plate 220. The rotating connector 211 is rotatably connected to the side end of the base 100. The cover plate 220 is slidably connected to the rotating connector 211. The cutting member 400 is mounted on the lower end face of the cover plate 220. The pressing member 500 is mounted on the lower end face of the cover plate 220 and located outside the cutting member 400.

[0040] After the cutting member 400 cuts the shrimp head, the bottom end of the squeezing member 500 contacts the tail of the shrimp. Then, the cover plate 220 is pushed along the rotating connector 211. The cover plate 220 drives the squeezing member 500 to gradually squeeze from the tail of the shrimp towards the head. During this process, the force of the user pushing the cover plate 220 is decomposed into two parts. One part of the force causes the cover plate 220 to move forward with the squeezing member 500, and the other part of the force presses down on the shrimp tail through the squeezing member 500. In this way, when pushing the cover plate 220, the squeezing member 500 can squeeze the shrimp meat out of the shrimp shell while pressing down on the shrimp shell. The operation is convenient and brings great convenience to peeling.

[0041] In this embodiment, the rotating connector 211 is hinged to the side end of the base 100. The cover plate 220 passes through the rotating connector 211 and is slidably connected to it. The slidable connection between the cover plate 220 and the rotating connector 211 can be achieved by each of them being provided with matching elastic teeth, or other structures capable of achieving a slidable connection can be provided as needed by those skilled in the art.

[0042] In another embodiment of the invention, such as Figure 1 and Figure 3 As shown, the upper cover 200 includes a connecting rod 212 and a cover plate 220. The connecting rod 212 is rotatably connected to the side end of the base 100; the cover plate 220 is slidably connected to the connecting rod 212; the cutting member 400 is installed on the lower end face of the cover plate 220; the extruding member 500 is installed on the lower end face of the cover plate 220 and located outside the cutting member 400. Through the sliding connection between the cover plate 220 and the connecting rod 212, relative sliding occurs between the connecting rod 212 and the cover plate 220. The connecting rod 212 also has a pushing and guiding function when pushing the cover plate 220, allowing the cover plate 220 to slide accurately along the connecting rod 212. This ensures that, provided the shrimp tail is correctly positioned, the cover plate 220 stably extrudes the shrimp tail to squeeze out the shrimp meat.

[0043] Specifically, after the cutting member 400 cuts the shrimp head, it pushes the cover plate 220 along the connecting rod 212. While the cover plate 220 slides along the connecting rod 212, the cover plate 220 drives the extruder 500 to gradually extrude from the tail of the shrimp towards the head of the shrimp tail until the shrimp meat is squeezed out of the shrimp shell.

[0044] In another embodiment of the invention, such as Figure 1 and Figure 3 As shown, the extrusion member 500 includes two mounting plates 511 and at least one rolling member 520. The two mounting plates 511 are mounted on the lower end face of the cover plate 220, and the rolling member 520 is rotatably mounted between the two mounting plates 511. When the extrusion member 500 rotates, it gradually extrudes the shrimp meat from the tail to the head of the shrimp tail until the shrimp meat is squeezed out of the shell. The rolling member 520 is cylindrical. During the process of the cover plate 220 gradually pressing down, the rolling member 520 first contacts the tail of the shrimp tail. During the process of pushing the cover plate 220, the cover plate 220 drives the rolling member 520 to move. The rolling member 520 rolls while moving. During the rolling process, the rolling member 520 exerts pressure on the shrimp tail to press it tightly against the elastic placement member 300, and also exerts a squeezing force to squeeze the shrimp meat out of the shell. Finally, the shrimp meat is squeezed out, thus achieving peeling.

[0045] The number of the rolling elements 520 can be set as needed. When multiple rolling elements 520 are set, the contact area between the rolling elements 520 and the shrimp tail is increased, so as to achieve more stable and faster extrusion of shrimp meat.

[0046] In another embodiment of the invention, such as Figure 1 and Figure 4 As shown, the extrusion member 500 includes two rotating shafts 512 and two rolling members 520. The two rotating shafts 512 are respectively installed on the lower end face of the cover plate 220, and the two rolling members 520 are rotatably installed on the two rotating shafts 512, with a gap between the two rolling members 520. When the cover plate 220 is pushed, the two rolling members 520 are driven forward and gradually contact the shrimp tail. The shrimp tail passes through the gap, and the two rolling members 520 rotate and simultaneously squeeze the shrimp meat out of the shrimp shell. After the shrimp meat is squeezed out, it does not pass through the gap and falls to the inside of the rolling member 520, while the shrimp shell is carried to the outside of the rolling member 520 through the gap. This achieves the separation of shrimp meat and shrimp shell, allowing the shrimp shell and shrimp meat to be placed separately, which is convenient for eating shrimp meat and discarding shrimp shells, greatly improving the user experience.

[0047] In another embodiment of the invention, such as Figure 1 , Figure 2 and Figure 4As shown, the base 100 has side plates 110 on both sides, and the two side plates 110 are provided with first pushing teeth 120. The two rolling elements 520 are provided with second pushing teeth 521. The second pushing teeth 521 are matched with the first pushing teeth 120 so that the first pushing teeth 120 push against the second pushing teeth 521, causing the two rolling elements 520 to rotate and squeeze out shrimp meat.

[0048] In this embodiment, the elastic placement member 300 is disposed between the two side plates 110. During the pressing process, the rolling member 520 gradually moves down between the two side plates 110 and contacts the first pushing teeth 120 on the two side plates 110. Under the interaction of the second pushing teeth 521 and the first pushing teeth 120, the rolling member 520 is pushed to rotate, thereby increasing the rate of extruding shrimp meat.

[0049] In another embodiment of the invention, such as Figures 1-3 As shown, the cutting component 400 includes an adjusting rod 410 and a cutting blade 420. The adjusting rod 410 is slidably mounted on the cover plate 220, and the cutting blade 420 is connected to the adjusting rod 410. Because the adjusting rod 410 is slidably mounted on the cover plate 220, its position on the cover plate 220 can be adjusted, thereby adjusting the distance between the cutting blade 420 and the rolling component 520. This allows for the removal of shrimp heads of different sizes, making it convenient for users.

[0050] The cutting disc 420 can be made from a complete, flat metal sheet, plastic sheet, or other sheet material. Alternatively, the cutting disc 420 can also be made from a metal strip twisted into a sharp shape for cutting.

[0051] In this embodiment, the cutting blade 420 is made of a metal strip, and the cover plate 220 has a through mounting hole 221. The adjusting rod 410 is slidably mounted in the mounting hole 221, and both ends of the cutting blade 420 are fixedly connected to both ends of the adjusting rod 410. By sliding the adjusting rod 410 along the mounting hole 221, the distance between the cutting blade 420 and the rolling element 520 can be adjusted.

[0052] In another embodiment of the invention, such as Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the top of the adjusting rod 410 is provided with a locking protrusion 411, and the cover plate is provided with a locking tooth 213. The locking tooth 213 is matched with the locking protrusion 411 so that when the cutting blade 420 cuts the shrimp head, the locking protrusion 411 of the adjusting rod 410 engages with the locking tooth 213 and keeps the adjusting rod 410 and the cover plate 220 relatively fixed.

[0053] In this embodiment, the cover plate 220 includes a cover plate body 224 and a pressure cap 225. The pressure cap is placed on the cover plate body to form the mounting hole 221, and the adjusting rod 410 is slidably installed in the mounting hole 221. The locking tooth 213 is disposed in the mounting hole 221, and the locking protrusion 411 of the adjusting rod 410 faces the locking tooth 213.

[0054] When cutting the shrimp head, the shrimp head abuts against the cutting blade 420, and the cutting blade 420 pushes against the adjusting rod 410. The locking protrusion 411 of the adjusting rod 410 engages with the locking tooth 213, thereby fixing the relative position of the adjusting rod 410 and the cover plate 220. This serves to fix the cutting blade 420 when cutting the shrimp head, preventing misalignment during cutting and greatly improving the cutting effect.

[0055] The mounting hole 221 is provided through the cover plate 220 and is rectangular in shape to match the sliding of the adjusting rod 410.

[0056] In another embodiment of the invention, such as Figures 1-3 As shown, the elastic placement member 300 includes a first support member 310 and a second support member 320. The first support member 310 is connected to the base 100, and the second support member 320 is connected to the first support member 310 and is arched.

[0057] Both the first support member 310 and the second support member 320 are elastic, so that when cutting the whole shrimp, the first support member 310 and the second support member 320 can change their shape as the cover plate 220 is pressed down, so as to change the orientation of the whole shrimp and make it easier to peel.

[0058] When the rolling element 520 presses down to squeeze the shrimp tail, the first support 310 undergoes elastic deformation and gradually makes the shrimp tail placed on the first support 310 approach a horizontal state. At this time, pushing the cover plate 220 drives the rolling element 520 to squeeze the shrimp tail, which is more convenient and stable.

[0059] The middle part of the first support member 310 is concave towards the base 100, so that when the shrimp tail is squeezed, the concave shape has a fixing effect on the shrimp tail and prevents the shrimp tail from moving forward.

[0060] Furthermore, due to the elasticity of the first support member 310 and the second support member 320, when the cutting blade 420 cuts the shrimp head, the second support member 320 can provide elastic force towards the cutting blade 420, thus ensuring that both sides of the shrimp head are subjected to force, increasing the cutting speed. When extruding the shrimp meat, the first support member 310 provides elastic force towards the shrimp tail, which, in conjunction with the extrusion force of the rolling member 520 on the shrimp shell, improves the stability and the rate of shrimp meat extrusion during the process.

[0061] The arched shape can be a sharp arch or a smooth, curved arch bridge, giving the elastic placement member 300 a curved arc that fits the shape of cooked or raw shrimp. When placing a whole shrimp on the elastic placement member 300, the shrimp head can be placed directly on the second support member 320, and the shrimp tail can be placed directly on the first support member 310, achieving precise placement without the need for extra operations to place the whole shrimp, and facilitating subsequent cutting of the shrimp head and peeling of the shrimp meat.

[0062] In addition, the protrusion may be provided on the first support member 310 or the second support member 320, or both the first support member 310 and the second support member 320 may be provided with the protrusion.

[0063] In addition, after the shrimp meat is squeezed out, the elastic placement component 300 resets and pops out the shrimp shell, eliminating the need to separately remove the shrimp shell and improving the convenience of use.

[0064] In this embodiment, both the first support member 310 and the second support member 320 are made of metal strips. Alternatively, the first support member 310 and the second support member 320 may also be made of high-strength, high-temperature resistant rubber or other materials.

[0065] In another embodiment of the invention, such as Figure 1 and Figure 5 As shown, the peeler also includes a guide 600, which is rotatably mounted on the base 100. One side of the guide 600 has a toggle block 610, and the other side has a weight block 620. The weight block 620 ensures that the side of the guide 600 with the weight block 620 is heavier than the side without it, causing the guide 600 to tilt towards the side with the weight block 620 under normal conditions.

[0066] By setting the actuating block 610, after the cutting blade 420 cuts the shrimp head, the head of the cutting blade 420 pushes against the actuating block 610, and the guide 600 tilts to one side of the actuating block 610, so that the shrimp head falls out from one side of the actuating block 610.

[0067] Next, during the process of squeezing out the shrimp meat, the cutting blade 420 gradually moves away from the agitator 610 until it no longer contacts it. Under the weight of the weight block 620, the guide 600 gradually returns to its original position, that is, it returns to a state of tilting towards the weight block 620. After the shrimp meat is squeezed out, it falls and passes through one side of the weight block 620. In this way, through the arrangement of the guide 600, the agitator 610 and the weight block 620, the shrimp meat and shrimp head fall from both sides of the guide 600 respectively, making it convenient to eat without the need for manual separation, thus improving the convenience of use.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

When the extrusion member rotates, it gradually extrudes the shrimp meat from the tail end to the head end of the shrimp tail until the shrimp meat is squeezed out of the shrimp shell.

5. The sheller according to claim 2 or 3, characterized in that, The extrusion component includes two rotating shafts and two rolling elements. The two rotating shafts are respectively installed on the lower end face of the cover plate, and the two rolling elements are rotatably installed on the two rotating shafts, with a gap between the two rolling elements. When the cover plate is pushed, the two rolling elements rotate and squeeze the shrimp meat out of the shrimp shell.

6. The sheller according to claim 5, characterized in that, The base has side plates on both sides, and the two side plates have first pushing teeth. The two rolling parts have second pushing teeth. The second pushing teeth are matched with the first pushing teeth so that the first pushing teeth push against the second pushing teeth, causing the two rolling parts to rotate and squeeze out shrimp meat.

7. The sheller according to claim 2 or 3, characterized in that, The cutting component includes an adjusting rod, which is slidably mounted on the cover plate. The cutting blade is connected to the adjusting rod. The top of the adjusting rod is provided with a locking protrusion, and the cover plate is provided with locking teeth. The locking teeth are matched with the locking protrusion so that when the cutting blade cuts the shrimp head, the locking protrusion of the adjusting rod engages with the locking teeth and keeps the adjusting rod and the cover plate relatively fixed.
