Description

Technical Field

[0001] This utility model relates to the technical field of shellfish opening devices, specifically a shellfish opening and meat extraction device. Background Technology

[0002] The laboratory tests the meat and mucus indicators of live shellfish to accurately assess their physiological state and quality characteristics: meat indicators reflect their safety and nutritional value for consumption, providing a basis for food safety supervision and optimization of aquaculture; mucus indicators reflect the health status, environmental adaptability and metabolic activity of shellfish, and have important reference value for studying the physiological mechanisms of shellfish and disease prevention and control.

[0003] However, currently, most laboratory methods involve manually prying open shells with knives to extract the meat. This method is difficult to control precisely, easily leading to shell breakage, cuts to the meat, and damage to the sample's integrity, directly affecting the test results for meat quality indicators. Furthermore, manual operation is time-consuming and labor-intensive, and also carries a certain risk of hand injuries. Therefore, this invention provides a shellfish opening and meat extraction device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model discloses a shellfish opening and meat extraction device, including a base 1, a lifting mechanism 2, a pressing mechanism 3, and an opening head 4. The lifting mechanism 2 is installed on the upper surface of the base 1, and the pressing mechanism 3 is installed on the lifting mechanism 2 and can be adjusted up and down by the lifting mechanism 2.

[0024] Specifically, the lifting mechanism 2 includes a housing 21 whose lower end is fixedly connected to the base 1. A lead screw 23 is rotatably connected inside the housing 21. A lifting seat 22 is sleeved on the outer end of the lead screw 23. A handwheel 25 is fixedly connected to the outer end of the lead screw 23. Guide rods 24 are fixedly connected to both sides inside the housing 21. The two sides of the lifting seat 22 are slidably sleeved with the guide rods 24. In use, rotating the handwheel 25 drives the lead screw 23 to rotate, thereby driving the lifting seat 22 to move linearly. Because the guide rods 24 restrict the rotational freedom of the lifting seat 22, stable lifting is ensured.

[0025] The outer side of the outer shell 21 is fixedly connected to a cover plate 26. The cover plate 26 can block debris that may appear during the opening process. Two through slots are opened on the inner side of the cover plate 26. The outer protruding part of the lifting seat 22 extends out of the through slot and is fixedly installed with a connecting seat 27. The connecting seat 27 is fixedly connected to the mounting plate 31.

[0026] Since the pressing mechanism 3 has a small pressing stroke, the lifting mechanism 2 can be set to effectively increase the range of shellfish that the pressing mechanism 3 can adapt to, expand the applicability of the device, and prevent shell opening failure due to differences in shellfish size.

[0027] In this embodiment, the pressing mechanism 3 includes a mounting plate 31. Two connecting frames 32 are fixedly mounted on the front end face of the mounting plate 31. A connecting rod 33 is fixedly sleeved between the two connecting frames 32. A movable frame 34 is slidably sleeved on the outer end of the connecting rod 33. A limiting sleeve 35 is fixedly sleeved on the middle part of the connecting rod 33. A connecting rod 38 is rotatably connected to one side of the limiting sleeve 35. A connecting rod 37 is rotatably connected to the upper end of the connecting rod 38. The middle part of the connecting rod 37 is rotatably connected to the upper end of the movable frame 34, and a handle 39 is fixedly sleeved on the end. The handle 39 and the two connecting rods form a lever structure, which can reduce the operating force and make the opening process easier.

[0028] The shell-opening head 4 is detachably installed at the lower end of the movable frame 34. Specifically, the shell-opening head 4 includes a blade 41 with a vertically downward blade and a sharp edge. A blade holder 42 is fixedly installed at the upper end of the blade 41. The blade holder 42 is installed and fixed to the lower end of the movable frame 34 by screws. The detachable design makes it easy to replace the blade 41 according to the type of shellfish (such as different thickness blades), thus improving adaptability.

[0029] Specifically, pulling down the handle 39 causes the movable frame 34 to slide down along the connecting rod 33 via the lever transmission of connecting rod 37 and connecting rod 38. The shell-opening head 4 then presses down and cuts into the gap of the shell, prying it open.

[0030] In this embodiment, the front end of the limiting sleeve 35 is provided with a sliding groove, through which the movable frame 34 slides. The limiting sleeve 35 is used to limit the maximum downward sliding distance of the movable frame 34, prevent excessive downward pressure, and protect the shell opening head 4 and the shellfish.

[0031] A spring 36 is sleeved on the outer end of the connecting rod 33. The two ends of the upper end of the spring 36 abut against the movable frame 34 and the limiting sleeve 35, respectively. The spring 36 provides a restoring force when the movable frame 34 rises, and at the same time uses its elasticity to maintain the raised state of the movable frame 34. In addition, the spring 36 also has a certain buffering effect to prevent excessive force during operation, reduce the problem of shell breakage and meat damage, and ensure that the experimental samples meet the requirements.

[0032] In this embodiment, a pressure-bearing seat 5 is fixedly installed on the upper end face of the base 1 directly below the shell opening head 4. A groove 6 is provided in the middle of the upper end face of the pressure-bearing seat 5. The pressure-bearing seat 5 is used to place shellfish, and the groove 6 at its upper end can restrict the sliding of the shellfish.

[0033] The working principle and usage process of this utility model are as follows: When in use, first adjust the height of the pressing mechanism 3 according to the size of the shellfish through the lifting mechanism 2 until the distance between the shell opening head 4 and the pressure seat 5 is appropriate.

[0034] Next, place the shellfish into the groove 6 of the pressure seat 5. The groove 6 restricts the shellfish's sliding, ensuring that the shell's crevices are aligned with the shell-opening head 4. Pull the handle 39 downwards. Through the lever transmission of connecting rod 1 37 and connecting rod 2 38, the movable frame 34 slides down along the groove of the connecting rod 33. The shell-opening head 4 is pressed down accordingly, and the sharp blade 41 cuts into the shell's crevices and pries it open. The limiting sleeve 35 limits the maximum sliding distance of the movable frame 34 to prevent excessive pressure. The spring 36 buffers the downward pressure, reducing shell breakage and meat damage.

[0035] After opening the shell, release the handle 39. The spring 36 provides a restoring force, causing the movable frame 34 and the shell-opening head 4 to move upward and return to their original position. Remove the shelled shell and extract the meat. To process different types of shellfish, simply remove the screws and replace the corresponding blade 41.
