Description
Technical Field
[0001] This utility model relates to the technical field of aquatic product processing equipment, and in particular to a snail tail-cutting device. Background Technology
[0002] The Chinese river snail, scientifically known as *Viviparus sinensis*, is widely distributed in freshwater lakes, reservoirs, rice paddies, ponds, and ditches throughout my country. Due to its delicious taste, rich nutrition, and medicinal properties such as clearing heat, quenching thirst, and improving eyesight, it has become a popular aquatic product, especially in southern China where it is considered a delicacy. When stir-frying river snails, the tail end must be removed beforehand to prevent harmful substances such as metabolic waste, bacteria, and parasites from being ingested and posing a health risk.
[0003] Currently, most snail tail removal is done manually. First, the snail's tail is moved into the hole of a knife, then the knife is swung to cut it off. Because the hand needs to hold the scissors, the person is easily cut by the swinging knife, which can prevent further work, making it quite troublesome. Furthermore, some snail shells are too hard to cut with ordinary scissors or pliers. Some existing technologies exist; seafood processing enterprises use large industrial roller-type tail-cutting machines. These machines use centrifugal force to make the snail's tail point in a uniform direction, and then a tail-cutting blade is used to remove the tail. However, these machines are expensive. Therefore, there is a particular need for a snail tail-cutting device that is easier for users to operate and has a lower cost. Utility Model Content
[0004] The purpose of this utility model is to provide a snail tail-cutting device, which aims to solve the risk problem existing in the snail tail-cutting process mentioned above, ensure the snail tail-cutting operation, and significantly reduce the actual device production cost.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A snail tail-cutting device, comprising:
[0007] case;
[0008] A tail-cutting blade disc is rotatably mounted on the housing, and a power mechanism drives the tail-cutting blade disc to rotate.
[0009] A tail-cutting slide is installed on the shell and is provided with a fixing part for fixing the snail whose tail is to be cut. The tail of the snail protrudes from the plate surface of the tail-cutting slide.
[0010] The tail-cutting slide is configured to move along the shell and bring the tail of the snail to be cut closer to or further away from the rotating surface of the tail-cutting disc, so that the tail-cutting disc performs a cutting operation on the tail of the snail.
[0011] This utility model also has the following technical features:
[0012] In one embodiment of this utility model, the tail-cutting slide is vertically slidably disposed on the shell, the surface of the tail-cutting disc is vertical, and the tail-cutting slide slides vertically such that the tail of the snail to be cut is close to or far away from the surface of the tail-cutting disc.
[0013] In one embodiment of this utility model, the fixing part is a fixing hole opened in the tail-cutting slide, the diameter of the fixing hole is adjustable, and the tail of the snail to be cut protrudes from one end of the fixing hole.
[0014] In one embodiment of the present invention, the fixing part includes multiple sets of through holes formed on the tail-cutting slide, the multiple sets of through holes having different diameters, the installation position of the tail-cutting slide and the housing being adjustable, and the position of the multiple sets of through holes on the housing being adjustable.
[0015] In one embodiment of this utility model, a reset member is provided on the housing, which is used to reset the tail-cutting slide.
[0016] In one embodiment of this utility model, a rectangular channel is provided on the housing, the tail cutting disc is located in the rectangular channel, the rectangular channel is arranged vertically, the upper and lower ends of the rectangular channel are open, the upper end of the rectangular channel is the inlet, and the lower end of the rectangular channel is the outlet.
[0017] In one embodiment of the present invention, the housing is provided with a snap-fit track, the snap-fit track is arranged vertically, and the two sides of the tail-cutting slide are slidably disposed in the snap-fit track, the tail-cutting slide forming part of the sidewall of the rectangular channel.
[0018] In one embodiment of the present invention, a waste material receiving tray is further provided on the housing, and the waste material receiving tray is arranged below the lower end of the rectangular channel.
[0019] In one embodiment of the present invention, a limiting plate is provided on the outer wall of the rectangular channel. The limiting plate is vertical and arranged close to the tail-cutting slide plate. The tail-cutting slide moves up and down and its lower end face is close to or away from the upper end face of the limiting plate.
[0020] In one embodiment of this utility model, the upper end surface of the limiting plate is provided with a notch for accommodating snails.
[0021] In one embodiment of this utility model, the power mechanism includes a drive motor, which is horizontally arranged in the receiving cavity of the housing. A motor mounting plate is provided on the body of the drive motor, the motor mounting plate is fixed on the housing, and the drive motor shaft extends into the rectangular channel and is fixed to the tail cutting disc.
[0022] Compared with existing technologies, the beneficial effects of this utility model are reflected in the following: by setting a movable tail-cutting slide plate, in conjunction with a rotating tail-cutting blade, an integrated operation logic of "fixing the snail + moving the feeding + rotating cutting" is realized. The operator only needs to fix the snail on the fixed part of the tail-cutting slide plate, and can control the distance between the snail's tail and the blade by moving the tail-cutting slide plate to complete the cutting action. No two people are required; a single person can easily operate it, effectively simplifying the process and improving tail-cutting efficiency. The fixed part of the tail-cutting slide plate can stably restrict the snail's position, preventing the hand from being close to the rotating blade. Structurally, this avoids the risk of direct contact between the hand and the blade during manual operation, completely solving the problem of easy cuts in traditional manual tail-cutting, ensuring the operator's personal safety, and reducing processing interruptions due to injury. The overall structure of the device is simple, mainly composed of a shell, tail-cutting blade, tail-cutting slide plate, and power mechanism. With fewer parts and simpler assembly, the manufacturing cost is far lower than that of large industrial-grade drum-type tail-cutting machines, meeting the needs of small-scale scenarios such as home processing and small workshops.

[0035] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0036] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0037] It should be noted that most snail tails are removed manually. First, people move the snail's tail into the hole of a cleaver, then swing the cleaver to cut off the tail. Since the hands need to hold the cleaver, people are easily cut by the swinging cleaver, making it impossible to continue working. Also, it requires two people to work together to remove the snail's tail, which is quite troublesome. Existing technologies include large-scale industrial drum-type snail tail-cutting machines used in aquatic product processing enterprises. These machines utilize centrifugal force to orient the snails' tails in a uniform direction before using tail-cutting blades to remove them. However, these machines are costly. Therefore, a snail tail-cutting device is proposed, comprising: a shell 10; a tail-cutting disc 20 rotatably mounted on the shell 10, driven by a power mechanism; and a tail-cutting slide 30 mounted on the shell 10, with a fixing part for securing the snails to be cut. The tail of the snail protrudes from the surface of the slide 30. The slide 30 is configured to move along the shell 10, allowing the tail of the snail to approach or move away from the rotating surface of the tail-cutting disc 20, thus enabling the tail-cutting disc 20 to perform the tail-cutting operation.
[0038] In one embodiment, see Figure 6 and Figure 3 The tail-cutting slide 30 is a thin plate with a fixing part that can fix the snail to be cut. When the operator places the snail inside the fixing part, the snail's tail can protrude from the plate surface of the tail-cutting slide 30. By manually dragging the tail-cutting slide 30 along the shell 10, the snail's tail is brought close to the tail-cutting blade 20. The high-speed rotating tail-cutting blade 20 can effectively cut off the snail's tail, especially for removing the tail of harder snails.
[0039] In one embodiment, see Figure 4 As shown, the housing 10 is in the shape of a rectangular box and can be placed stably on a workbench or other work platform, making it convenient for operators to hand-feed materials.
[0040] In one embodiment, the surface of the tail-cutting disc 20 is horizontal, and the surface of the tail-cutting slide 30 is horizontal. After the snail to be cut is placed in the fixing part, the tail of the snail extends out of the lower surface of the tail-cutting slide 30. By dragging the tail-cutting slide 30 to move horizontally, the snail tail end extending out of the lower surface of the tail-cutting slide 30 is brought close to the tail-cutting disc 20 to cut the snail tail.
[0041] In another embodiment, see Figures 1 to 4 As shown, the tail-cutting slide 30 is vertically slidably disposed on the shell 10, the disc surface of the tail-cutting blade 20 is vertical, and the tail-cutting slide 30 slides vertically such that the tail of the snail to be cut is close to or far away from the disc surface of the tail-cutting blade 20.
[0042] In the above embodiment, the operator pinches the head of the snail, causing the tail to extend into the fixed part, and the tail of the snail to extend out of the plate surface of the tail-cutting slide 30. The operator manually drags the tail-cutting slide 30 vertically, so that the tail of the snail is close to the plate surface of the tail-cutting disc 20, thereby enabling the cutting of the snail's tail.
[0043] In another embodiment (not shown in the figure), the fixing part is a fixing hole opened in the tail-cutting slide 30. The diameter of the fixing hole is adjustable, and the tail of the snail to be cut protrudes from one end of the fixing hole.
[0044] In the above embodiment, the tail-cutting slide 30 includes two pieces. One tail-cutting slide 30 has a semicircle, and the other tail-cutting slide 30 also has a semicircle. The two tail-cutting slides 30 are movably connected and can be fixed by buckles or screws, thereby achieving the purpose of adjusting the size of the fixing hole.
[0045] In another embodiment, which is also a preferred embodiment, see [reference needed]. Figure 2 and Figure 6As shown, the fixing part includes multiple sets of through holes 31 formed on the tail-cutting slide 30. The diameter of the multiple sets of through holes 31 is different. The installation position of the tail-cutting slide 30 and the housing 10 is adjustable, and the position of the multiple sets of through holes 31 on the housing 10 is adjustable.
[0046] In the above embodiments, the diameter of the through hole 31 varies, which can accommodate snails of various sizes for tail cutting. The diameter of the through hole 31 should not be too large, only enough to allow the tip of the snail's tail to protrude, avoiding the snail's head from protruding out of the entire through hole 31.
[0047] In the above embodiments, the tail-cutting slide 30 can be a square plate with four sets of through holes 31. After the tail-cutting slide 30 is installed in place with the shell 10, the through holes 31 of different diameters can face downwards, so that the tail tip of the snail to be cut can be inserted into the downward-facing through hole 31. The tail-cutting slide 30 is then dragged downwards to contact the tail-cutting blade 20, thereby realizing the tail-cutting action. In some embodiments, the through hole 31 can be a circular hole, a square hole, or an irregularly shaped hole, as long as the tail tip of the snail is extended.
[0048] In another embodiment, the tail-cutting slide 30 can be replaced to facilitate adjustment of different diameter through holes 31, thereby increasing the applicability of the tail-cutting device.
[0049] In one embodiment, to facilitate the operator to hold the snail by hand and move the tail-cutting slide 30 to slide on the shell 10, a rectangular channel 11 is provided on the shell 10, the tail-cutting disc 20 is located in the rectangular channel 11, the rectangular channel 11 is arranged vertically, the upper and lower ends of the rectangular channel 11 are open, the upper end of the rectangular channel 11 is the inlet, and the lower end of the rectangular channel 11 is the outlet.
[0050] In this embodiment, when the snail is held by hand and the tail-cutting slide 30 slides on the shell 10, the snail's tail slides along the rectangular channel 11 until the snail's tail contacts the tail-cutting disc 20 to cut off the snail's tail tip. When the cut snail tail tip can fall down along the lower end of the rectangular channel 11, the operator can also observe the use of the tail-cutting disc 20 through the upper entrance of the rectangular channel 11.
[0051] In one embodiment, see Figure 3 As shown, in order to facilitate the operator to squeeze the snail by hand, so that the tail-cutting slide 30 slides vertically on the shell 10, the shell 10 is provided with a locking track 12, the locking track 12 is arranged vertically, and the two sides of the tail-cutting slide 30 are slidably disposed in the locking track 12, and the tail-cutting slide 30 constitutes part of the side wall of the rectangular channel 11.
[0052] In the above embodiment, when the operator pinches the snail and drags the tail-cutting slide 30 vertically downward along the locking track 12, the tip of the snail's tail can be cut off. The operator can also pinch the snail and drag the tail-cutting slide 30 upward to remove the snail with the cut tail from the through hole 31.
[0053] In one embodiment, the housing 10 is further provided with a waste receiving tray 40, which is located below the lower end of the rectangular channel 11.
[0054] In one embodiment, see Figure 4 and Figure 5 As shown, the waste receiving tray 40 is a rectangular or circular tray and is detachably connected to the shell 10, facilitating the removal of the cut snail tail tip waste. Figure 5 In the middle, the waste receiving tray 40 is equipped with two sets of insertion platforms, see reference. Figure 4 The housing 10 is provided with two sets of plug-in pins, which are inserted into the two sets of plug-in platforms on the waste receiving tray 40, so as to realize the detachable connection between the waste receiving tray 40 and the housing 10.
[0055] In one embodiment, the housing 10 is provided with a reset member 13, which is used to reset the tail-cutting slide 30.
[0056] In one embodiment, see Figure 3 As shown, to facilitate the return of the tail-cutting slide 30 to the upward position, the return element 13 is a return spring set in the locking track 12. The return spring is vertical and its upper end abuts against the lower end face of the tail-cutting slide 30. The return spring is a compression spring. When the tail-cutting slide 30 is downward, the return spring can be compressed. After the snail tail tip is cut off, the hand is released, and the return spring 13 is lifted and reset under the action of the reset force.
[0057] The aforementioned locking track 12 is a vertically arranged locking groove plate, and the reset spring is vertically arranged in the groove of the locking track 12.
[0058] In another embodiment, the reset member 13 is a tension spring disposed above the rectangular channel 11. The tension spring is vertical and its lower end abuts against the upper end of the tail-cutting slide 30. When the tail-cutting slide 30 is downward, the tension spring can be stretched. When the snail tail tip is cut off, the hand is released and the tension spring is lifted and reset under the action of the reset force.
[0059] In one embodiment, to limit the downward pressure of the tail-cutting slide 30, a limiting plate 111 is provided on the outer wall of the rectangular channel 11. The limiting plate 111 is vertical and arranged close to the plate surface of the tail-cutting slide 30. The tail-cutting slide 30 moves up and down and its lower end surface is close to or away from the upper end surface of the limiting plate 111.
[0060] In the above embodiment, after the snail's tail is placed in the through hole 31, when the tail-cutting slide 30 moves down until the snail's body abuts against the upper end face of the limiting plate 111, it can be ensured that the tail-cutting blade 20 cuts the snail's tail tip in place.
[0061] In one embodiment, the upper end face of the limiting plate 111 is provided with a notch 112 for accommodating snails, and the notch is semi-circular or small semi-circular.
[0062] For instructions on installing the power mechanism, please refer to [link / reference]. Figure 7 The power mechanism includes a drive motor 50, which is horizontally arranged in the receiving cavity of the housing 10. A motor mounting plate 51 is provided on the body of the drive motor 50. The motor mounting plate 51 is fixed on the housing 10, and the shaft of the drive motor 50 extends into the rectangular channel 11 and is fixed to the tail cutting disc 20 by a nut.
