Description

Technical Field

[0001] This invention relates to the technical field of fixing oysters before opening them, and in particular to a pry bar for opening oysters. Background Technology

[0002] In the catering, retail, food processing, and oyster farming industries, the oyster shucking and meat extraction process still heavily relies on manual labor. However, manual shucking has several significant drawbacks: low efficiency, high labor costs, operators are easily injured by tools or sharp oyster shells, and hygiene standards are difficult to standardize. Patent application CN109122806A discloses an oyster prying device, which consists of a lifting device, an upper fixing device, a lower fixing device, a prying device, and a control console. Its workflow is as follows: after the oyster is placed on the lower fixing device, the lifting device drives the upper fixing device downwards, so that the upper and lower fixing devices together secure the oyster; then, a worker aligns the pry bar with the oyster opening and, driven by an electromagnet, inserts the pry bar into the oyster to pry open the shell. This prying device has the following shortcomings: firstly, the oyster's fixing structure is complex, requiring the lifting device to provide binding force to secure the oyster. Secondly, prying requires considerable power to pry open the upper and lower fixing devices. Summary of the Invention

[0003] This invention provides a pry bar for opening oysters, which solves the problem that existing oyster fixing structures are complex and require additional power to fix the oysters.

[0004] This invention provides a pry bar for shucking oysters, including a positioning base. The positioning base has an inclined surface, a bottom surface, and a first engaging surface. The bottom surface is connected to the lower end of the inclined surface and the lower end of the first engaging surface. The first engaging surface is inclined towards the inclined surface or perpendicular to the bottom surface. The inclined surface, the bottom surface, and the first engaging surface together form a first limiting groove. The inclined surface has a second limiting groove that engages with the oyster shell. The slope of the bottom of the second limiting groove is less than the slope of the inclined surface. The width of the second limiting groove gradually increases from the bottom of the groove to the inclined surface.

[0005] Preferably, the bottom of the second limiting groove is provided with a third limiting groove, and the third limiting groove is connected to the second limiting groove.

[0006] Preferably, a second contact surface is provided above the first contact surface, the distance between the second contact surface and the inclined surface is greater than the distance between the first contact surface and the inclined surface, and the second contact surface is connected to the first contact surface through a connecting surface.

[0007] Preferably, the inclined surface is provided with a first clearance groove, which is located below the second limiting groove.

[0008] Preferably, the bottom surface extends into the third limiting groove, and a first drain hole is provided on the bottom surface. The first drain hole is located below the second limiting groove and the first clearance groove.

[0009] Preferably, the bottom of the third limiting groove is provided with a second drain hole that slopes downwards, and the opening of the second drain hole is connected to the bottom surface.

[0010] Preferably, the positioning seat is provided with a first mounting groove and a second clearance groove connected to the first mounting groove. A motor and a lever are respectively installed in the first mounting groove and the second clearance groove. The second clearance groove is connected to the first limiting groove, the second limiting groove and the third limiting groove respectively. The second clearance groove passes through the first drain hole.

[0011] Preferably, a cover plate is snapped onto the first mounting slot.

[0012] Preferably, the end of the positioning seat containing the second engaging surface is lower than the height of the inclined plane.

[0013] Preferably, it also includes a frame, on which an electric telescopic rod is provided, the electric telescopic rod being used to push the positioning seat to slide horizontally along the frame.

[0014] Compared with existing technologies, the present invention has a simple overall structure. Oysters are placed on an inclined surface, and the inclined surface, the included angle C, and the second limiting groove can restrict the oysters before they are opened, making it easy to fix the oysters. Secondly, the posture of the oysters lying on the inclined surface can be easily adjusted within this restriction. Thirdly, no other force is required to restrain them, saving energy.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] See attached document Figure 1This embodiment provides a pry bar for opening oysters, including a positioning base 1. The positioning base 1 is provided with an inclined surface 11, a bottom surface 12 and a first engaging surface 13. The bottom surface 12 is connected to the lower end of the inclined surface 11 and the lower end of the first engaging surface 13. The first engaging surface 13 is inclined towards the inclined surface 11 or perpendicular to the bottom surface 12. The inclined surface 11, the bottom surface 12 and the first engaging surface 13 together form a first limiting groove 14. The inclined surface 11 is provided with a second limiting groove 15 that cooperates with the oyster shell. The slope of the bottom of the second limiting groove 15 is less than the slope of the inclined surface 11. The width of the second limiting groove 15 gradually increases from the bottom of the groove to the inclined surface 11 so as to better fit the oyster shell. In this invention, oysters are placed on an inclined surface 11, with two oyster shells facing the inclined surface 11 and the first engaging surface 13 respectively (oyster shell A facing the first engaging surface 13 and oyster shell B facing the inclined surface 11). The top of the oyster is engaged within the angle C formed by the first engaging surface 13 and the bottom surface 12, and part of oyster shell B is embedded in the second limiting groove 15. This invention provides limited restraint to the oyster through the inclined surface 11, the angle C, and the second limiting groove 15. This restraint allows for fine-tuning of the oyster's placement, adjusting the gap between the two oyster shells so that the gap at the tail of the oyster is positioned in the downward direction of the drill bit. When the drill bit is used to drill downwards between the oyster shells, the inclined surface 11 and the angle C prevent the oyster from sliding downwards under the pressure of the drill bit, and the constraint of the second limiting groove 15 effectively prevents the oyster from swaying left and right under the pressure of the drill bit, thus ensuring that the oyster does not move. The overall structure is simple. Simply placing the oyster on the inclined plane 11 is sufficient to restrain it before opening. No additional clamps or force are needed to secure the oyster, making the oyster fixation method simple and easy to operate. Secondly, the posture of the oyster lying on the inclined plane 11 can be easily adjusted. Furthermore, when later inserting the oyster into the shell to pry it open, the energy required for shell A to flip upwards (without external restraint) is minimal.

[0020] As another embodiment of the present invention: refer to the appendix Figure 2 The bottom of the second limiting groove 15 is provided with a third limiting groove 16, which is connected to the second limiting groove 15. The second limiting groove 15 is located between the third limiting groove 16 and the first limiting groove 14. The second limiting groove 15 restricts the two sides of the oyster shell, and the third limiting groove 16 restricts the middle part of the oyster shell. The two work together to more stably restrain the oyster.

[0021] As another embodiment of the present invention: refer to the appendix Figure 4A second contact surface 17 is provided above the first contact surface 13. The distance between the second contact surface 17 and the inclined surface 11 is greater than the distance between the first contact surface 13 and the inclined surface 11. The second contact surface 17 is connected to the first contact surface 13 through a connecting surface 22. The first contact surface 13, the connecting surface 22, and the second contact surface 17 form a stepped structure. When the oysters are small, they are placed on the inclined surface 11, with the lower end of the oyster wedged into the angle formed by the first contact surface 13 and the bottom surface 12. When the oysters are large, they are placed on the inclined surface 11, with the lower end of the oyster wedged into the angle formed by the second contact surface 17 and the connecting surface 22. This structural design allows for the placement of different batches of oysters.

[0022] In another embodiment of the present invention, a first clearance groove 18 is provided on the inclined surface 11, and the first clearance groove 18 is located below the second limiting groove 15. Oysters have different shapes, and some oysters have a more protruding head (head facing down). In this case, the setting of the first clearance groove 18 can effectively prevent the oyster from interfering with the positioning seat 1. Through this structural design, oysters of various shapes can be easily placed on the inclined surface 11.

[0023] As another embodiment of the present invention: refer to the appendix Figure 3 The bottom surface 12 extends towards the third limiting groove 16. A first drainage hole 19 is provided on the bottom surface 12. The first drainage hole 19 is located below the second limiting groove 15 and the first clearance groove 18. The first drainage hole 19 is a vertical hole. Oysters may drip water when placed, and may also generate sewage and stains when opening the shells. This sewage and dirt can be discharged through the first drainage hole 19 to avoid affecting the subsequent opening of the oysters.

[0024] In another embodiment of the present invention, the bottom of the third limiting groove 16 is provided with a downwardly inclined second drain hole 20, and the opening of the second drain hole 20 is connected to the bottom surface 12. The design of the second drain hole 20 can effectively reduce the dead angle of draining.

[0025] In another embodiment of the present invention: the positioning base 1 is provided with a first mounting groove 21 and a second clearance groove 22 communicating with the first mounting groove 21. A motor 2 and a lever 3 are respectively installed in the first mounting groove 21 and the second clearance groove 22. The lever 3 is connected to the output shaft of the motor 2. The first mounting groove 21 is located on one side of the third limiting groove 16. The second clearance groove 22 communicates with the first limiting groove 14, the second limiting groove 15, and the third limiting groove 16, respectively, and passes through the first drain hole 19. The lever 3 is inclined relative to the first engaging surface 13. The motor 2 drives the lever 3 in the second clearance groove 22 to rotate upwards, and the lever 3 picks the oysters out of the first limiting groove 14, thus completing the unloading of the oysters. The motor 2 rotates in the opposite direction, and the lever 3 returns to its initial position. Through this structural design, automatic unloading is integrated into the positioning base 1, making the structure more compact and facilitating equipment miniaturization.

[0026] Specifically, lever 3 is made of PLA material, with its end covered with silicone, which reduces the impact on positioning seat 1 when picking out oysters.

[0027] Specifically, motor 2 is a servo motor, and the rotation angle of lever 3 can be adjusted via programming.

[0028] In another embodiment of the present invention, a cover plate 4 is snapped onto the first mounting groove 21 to protect the motor 2 inside the first mounting groove 21.

[0029] As another embodiment of the present invention: the end of the second locking surface 17 of the positioning seat 1 is lower than the height of the inclined surface 11. The end of the second locking surface 17 of the positioning seat 1 is the front end. Setting the front end lower makes it easier for the user to put the oysters on the inclined surface 11 from the front. When unloading later, the lever 3 can be rotated upward to easily pick the oysters out from the front end.

[0030] As another embodiment of the present invention, it also includes a frame 5, on which an electric telescopic rod 6 is provided. The electric telescopic rod 6 is used to push the positioning seat 1 to slide horizontally along the frame 5.

[0031] Specifically, the angle between the inclined plane 11 and the horizontal plane is 45°-60°, and this structural design facilitates the natural positioning of oysters under the action of gravity.

[0032] As another embodiment of the present invention: a sewage box 8 is provided below the positioning seat 1, and sewage and dirt on the positioning seat 1 are discharged into the sewage box 8 through the first sewage hole 19 and the second sewage hole 20, so as to avoid them remaining on the positioning seat 1 and affecting the subsequent opening of oysters.

[0033] In this invention, the user places the oyster on the inclined surface 11, with part of the oyster shell located within the second limiting groove 15. The top of the oyster is held within the included angle C. Lateral movement of the oyster allows for slight adjustment of its posture, aligning the oyster's tail gap with the downward direction of the drill bit. The drill bit then penetrates the oyster shell through the gap, slightly opening the oyster. The electric telescopic rod 6 drives the positioning seat 1 to move backward, causing the oyster shell A to flip upward under the resistance of the drill bit, thus completing the oyster opening. The overall structure is simple; simply placing the oyster on the inclined surface 11 provides sufficient restraint before opening, making it easy to secure. Furthermore, this restraint allows for easy fine-tuning of the oyster's posture while it lies on the inclined surface. No additional force is required to restrain it, saving energy. Subsequent shell opening also eliminates the need for additional power to counteract the restraining force applied to the oyster, further conserving energy.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
