Description

Technical Field

[0001] This invention relates to a shell-breaking device for snails, and more particularly to a laboratory shell-breaking device for spiral snails. Background Technology

[0002] The whelk is a type of marine gastropod that is a common snail species in coastal areas. The whelk is characterized by its pointed and slender tail, about the size of a fingernail. It lives mostly in intertidal mudflats and is a scavenger. It is distributed from south to north in my country, mainly in Zhejiang, Jiangsu, Guangdong and Fujian.

[0003] The toxins causing poisoning from whelks remain highly controversial. Some studies suggest paralytic shellfish toxins, others tetrodotoxins, and still others a combination of both. Detecting and analyzing the main chemical components responsible for whelk poisoning can provide a basis for preventing foodborne illnesses caused by whelks. Common methods for detecting and analyzing the main chemical components causing whelk poisoning include liquid chromatography-tandem mass spectrometry (LC-MS / MS) and post-column derivatization fluorescence spectrometry (PCFS). Before using these methods, the whelks require pretreatment such as meat extraction and homogenization.

[0004] The current method for extracting meat from whelks in the laboratory involves breaking the shell with a heavy object such as a hammer, and then separating the meat through centrifugation or vibration. However, this method of breaking the shell with a heavy object is not only time-consuming and laborious, but also inefficient and poses a safety hazard as it is easy to injure one's hand.

[0005] Furthermore, Chinese Patent Application Publication No. CN112075487A, published on December 15, 2020, discloses a shell-breaking machine for snails, comprising a shell-breaking support device, a rotating shell-breaking surface component, a snail-holding device, a fixing and limiting device, a storage support device, a drop switch device, a shell-breaking support device, a squeezing shell-breaking device, and a snail-holding device. The shell-breaking support device is connected to the rotating shell-breaking surface component, and four snail-holding devices are rotatably connected to the rotating shell-breaking surface component. The fixing and limiting device is connected above the rotating shell-breaking surface component and contacts the multiple snail-holding devices. The shell-breaking support device is fixedly connected to the storage support device, and a drop switch device is connected to the storage support device. The shell-breaking support device is also fixedly connected to the shell-breaking support device, and a squeezing shell-breaking device is connected to the shell-breaking support device. This shell-breaking device has a complex structure, large size and weight, and requires external power equipment such as a motor, making it inconvenient to transport and move, and lacking flexibility in use, thus it is not suitable for laboratory use. Summary of the Invention

[0006] This invention addresses the problems of existing shell-breaking methods that use heavy objects such as hammers to break the shells of whelks, which are time-consuming, labor-intensive, inefficient, and pose safety hazards due to the risk of injury. It provides a laboratory whelk shell-breaking device that is small in size, compact in structure, easy to use, labor-saving, highly efficient, and offers good shell-breaking effect, flexibility, and versatility.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a laboratory-use spiral shell-breaking device, comprising a platform and an extrusion base, wherein a housing is provided on the platform, and a rotating pressure roller is provided inside the housing. One end of the roller shaft of the rotating pressure roller is connected to a rocker arm. A plurality of extrusion protrusions are provided circumferentially on the roller surface of the rotating pressure roller. The length direction of the extrusion protrusions is the same as the axial direction of the rotating pressure roller. The thickness of the extrusion protrusions gradually increases in a clockwise direction. The outer surface of the extrusion protrusions is set as an outwardly convex arc surface to form an extrusion arc surface. The end face of the extrusion protrusion with the larger thickness forms a biting surface. The extrusion platform is located inside the machine housing and fixed to the platform by a horizontal position adjustment mechanism. The inner side of the extrusion platform is provided with an outwardly convex extrusion arc surface and an inwardly concave extrusion arc surface. The gap between the outwardly convex extrusion arc surface and the extrusion protrusion forms a first shell-breaking gap, and the gap between the inwardly concave extrusion arc surface and the extrusion protrusion forms a second shell-breaking gap. The upper opening of the first shell-breaking gap forms a feed inlet, and the lower opening of the second shell-breaking gap forms a discharge outlet. The top surface of the machine housing is provided with a feeding port, and the platform is provided with a dropping port. The feeding port is located above the feeding port, and the dropping port is located in front of the discharge outlet. This invention is primarily used in the laboratory for breaking open the shells of whelks to extract the meat. The rotating pressure roller can be turned manually by rotating the rocker arm, eliminating the need for external power equipment such as a motor, thus improving the flexibility of use. When the pressure roller rotates clockwise, material continuously enters the first and second shell-breaking gaps for compression and breaking. Rotating the pressure roller clockwise also allows the material to exit from both gaps. The thickness of the extrusion ridges gradually increases clockwise, creating a constricted structure in both the first and second shell-breaking gaps. This not only facilitates feeding and forward delivery but also gradually increases the pressure on the whelk as the pressure roller rotates. The invention achieves the purpose of crushing the shell of the whelk. Simultaneously, the extrusion arc surfaces—both the convex and concave ones—are without sharp edges, ensuring that the whelk's flesh is not damaged during shell breaking. The first and second shell-breaking gaps allow for secondary crushing, significantly improving the crushing effect. The biting surface presses the whelk into the first and second shell-breaking gaps, simultaneously pushing it to move clockwise (forward) for discharge. The position adjustment mechanism allows for adjustment of the extrusion platform's position, thereby adjusting the size of the first and second shell-breaking gaps. This allows the invention to be applied to whelks of different sizes while maintaining the shell-breaking effect, thus improving its versatility.

[0008] Preferably, the extrusion arc surface is provided with a plurality of interlocking grooves spaced circumferentially along the rotating pressure roller, and the length direction of the interlocking grooves is the same as the axial direction of the rotating pressure roller. The interlocking grooves can reduce the relative sliding between the textured screw and the extrusion arc surface, so as to ensure that there is sufficient force between the extrusion arc surface and the textured screw.

[0009] Preferably, the engagement groove is a U-shaped groove or a V-shaped groove.

[0010] Preferably, the convex and concave extrusion surfaces are provided with a plurality of protruding blades, which are spaced apart along the axial direction of the rotating pressure roller. The small contact area between the protruding blades and the spiral shell increases the pressure, allowing the spiral shell to break quickly under pressure, thus improving the shell-breaking efficiency and effect.

[0011] Preferably, the horizontal position adjustment mechanism includes a pad and an adjusting screw. The pad is fixed to the platform, and a slide plate is provided on the lower part of the outer side of the extrusion platform. Both the extrusion platform and the slide plate rest on the pad, and both the pad and the slide plate pass through the machine housing. The slide plate and the pad are detachably connected. A drive slider cavity is provided inside the pad, and a drive slider is provided inside the drive slider cavity. The upper part of the drive slider is fixedly connected to the slide plate. The adjusting screw is rotatably disposed inside the pad, passes through the drive slider, and is threadedly connected to the drive slider. In this invention, rotating the adjusting screw can drive the slide plate to move horizontally back and forth via the drive slider. The structure is simple and the operation is very convenient. The movement of the slide plate simultaneously drives the extrusion platform to move, and the size of the first and second shell-breaking gaps can be adjusted.

[0012] Preferably, the platform is provided with a guide groove, and the bottom surface of the slide plate is provided with a guide slide bar, which is slidably fitted with the guide groove.

[0013] Preferably, both the pad and the platform are provided with corresponding adjustment holes, and the slide is fastened to the pad and the platform as a whole by bolts passing through the adjustment holes.

[0014] Preferably, the upper part of the drive slider is inserted into the slide plate.

[0015] Preferably, the top surface of the casing is provided with a hopper, and the bottom outlet of the hopper is connected to the feeding port.

[0016] A guide trough is provided below the material discharge port, and the upper end of the guide trough is fixedly connected to the platform.

[0017] Therefore, the present invention has the following beneficial effects:

[0018] (1) The overall structure is compact and small in size. It does not require external power equipment such as motors and has good flexibility in use.

[0019] (2) The thickness of the extrusion rib gradually increases in the clockwise direction. This design makes the first and second shell-breaking gaps both have a narrowing structure in the clockwise direction, which is not only conducive to feeding and forward feeding, but also allows the pressure on the spiral snail to gradually increase as the pressure roller rotates, thereby achieving the purpose of crushing the spiral snail shell.

[0020] (3) The first and second shell-breaking gaps can be used to crush the spiral snails by secondary extrusion, which greatly improves the crushing effect;

[0021] (4) The size of the first shell-breaking gap and the second shell-breaking gap can be adjusted, so that the present invention can be applied to different sizes of textured snails, while ensuring the shell-breaking effect and having good versatility. Attached Figure Description

The thickness of the extrusion protrusions gradually increases in a clockwise direction. The outer surface of the extrusion protrusions is set as an outwardly convex arc surface to form an extrusion arc surface 7. The end face of the thicker end of the extrusion protrusion forms a biting surface 8. Several biting grooves 17 are spaced circumferentially on the extrusion arc surface along the rotating pressure roller. The length direction of the biting grooves is the same as the axial direction of the rotating pressure roller. The biting grooves are U-shaped grooves (e.g., Figure 5 As shown), the extrusion platform is located inside the machine housing and is fixed to the platform by a horizontal position adjustment mechanism.
