Description

Technical Field

[0002] Snails are commonly used as food in my country. When preparing snails, removing the tail (tip) is a crucial step. Because snails live in freshwater environments, the tail is where their excretory pores and intestines are located, making it prone to accumulating mud, excrement, and undigested food residue. Removing the snail's tail effectively reduces mud residue, preventing a gritty feeling or unpleasant taste when eating them.

[0003] Currently, snail tail removal is still mainly done manually, with workers or kitchen helpers using scissors or special tools to cut off the snail's tail one by one (usually cutting off 1 / 3 to 1 / 2 of its length). Its main disadvantages are as follows:

[0004] 1. Low processing efficiency and high labor costs;

[0020] This utility model has the following advantages compared with the prior art:

[0021] 1. When in use, the batch of snails to be processed is poured into the snail processing chamber. Through the coordinated action of the vibrating motor and the screw conveyor, the snails are automatically fed, oriented and continuously transported. With the help of the snail tail cutting mechanism and the snail tail breaking mechanism, the snail tail is cut off in an assembly line operation. The processing efficiency is several times higher than that of manual labor, the amount of manual labor is reduced and the risk of injury from manual operation is avoided.

[0022] 2. Adopting a dual-stage cutting design: The screw tail cutting mechanism pre-cuts the screw tail to form a slit using a disc-shaped cutter, and the screw tail breaking mechanism completely severs the screw tail at the lower end of the slit using a multi-blade cutter, avoiding tail breakage or residue caused by a single cut.

[0023] 3. Progressive cutting control: Multiple sets of snail tail cutting mechanisms are arranged in a gradient along the double guide rods. The sweeping area of ​​the multi-blade cutter gradually approaches the inner guide rod, realizing the increasing cutting depth of the snail tail, accurately adapting to snails of different sizes, and ensuring complete removal.

[0024] 4. Split-type vibration base: A sealing ring is installed between the upper and lower parts, which, together with the flexible protective sleeve located on the outside of the lower part, achieves double shock absorption, effectively isolates vibration from being transmitted to the ground, and improves equipment stability.

[0025] 5. Optimized snail fixing method: The arc-shaped transition section of the double guide rod can screen out unqualified snails (snails that are too small in size). The working section of the double guide rod, together with the screw head pressure plate, forms a three-dimensional fixing of "positioning on both sides of the screw head + pressure on the top of the screw head", which avoids displacement or rolling when cutting the screw tail and reduces the snail breakage rate.

[0026] 6. Modular and easy to maintain: The vibration base, screw tail cutting mechanism, and screw tail breaking mechanism are all modularly assembled, facilitating disassembly, cleaning, and component replacement. The disc cutter and multi-blade cutter are driven independently, allowing for individual repair in case of malfunction, reducing downtime.

Detailed Implementation Example 1

[0044] like Figure 1-12 As shown, the batch snail tail removal device includes a vibrating elevator, a snail arranging device, and a snail tail separation device.

[0045] The vibratory elevator includes a vibratory base 1 and a screw conveyor 2 connected sequentially from bottom to top.

[0046] The vibration base 1 contains a vibration motor (not shown in the figure), and the upper part of the vibration base 1 has a conical surface 11. The height of the conical surface 11 gradually decreases from the center to the periphery (forming a structure with a convex center and a sloping periphery, like an inverted funnel). The vibration base 1 includes a lower part 12, an upper part 13, and a flexible sheath 14. Both the lower part 12 and the upper part 13 are hollow cylindrical structures. The lower part 12 is open at the upper end, and the upper part 13 is open at the lower end. The lower part 12 and the upper part 13 are movably inserted into each other in an open-to-facing posture. Multiple sealing rings 100 are provided between the interlocking annular surfaces of the lower part 12 and the upper part 13. All the sealing rings 100 are arranged at intervals along the axial direction of the vibration base 1 to absorb the vibration of the upper part 13, weaken the vibration energy transmitted to the lower part 12, and improve the stability of the vibration base 1. The flexible sheath 14 tightly wraps around the lower body 12 to absorb vibrations from the lower body 12, weaken vibration energy transmitted to the ground, and improve the stability of the vibration base 1. Correspondingly, the vibration motor is fixedly installed inside the upper body 13, thereby directly driving the upper body 13 and components directly connected to its upper end to vibrate. Correspondingly, the conical surface 11 is located at the upper outer end of the upper body 13.

[0047] The screw conveyor 2 includes a screw plate 21 and a screw side plate 22. The screw plate 21 spirals upward from bottom to top, and the spiral radius gradually increases. A spiral path is provided on the upper surface of the screw plate 21. The lower end of the screw plate 21 is fixedly connected to the conical surface 11 and is relatively close to the outer edge of the conical surface 11. The screw side plate 22 is fixedly connected to the side of the screw plate 21 and is arranged along the extension direction of the screw plate 21. The screw conveyor 2 and the conical surface 11 of the vibrating base 1 together form a snail processing chamber. Specifically, the screw plate 21 and the screw side plate 22 of the screw conveyor 2 and the conical surface 11 of the vibrating base 1 together form a snail processing chamber.

[0048] The snail arrangement device includes double guide rods 3 and snail head pressure plate 4.

[0049] The double guide rod 3 includes two parallel and horizontally arranged guide rods. The rear ends of the two guide rods (i.e., the rear ends of the double guide rod 3) are free ends, and the front ends of the two guide rods (i.e., the front ends of the double guide rod 3) are respectively fixedly connected to the upper two sides of the spiral plate 21. A strip-shaped gap 200 is formed between the two guide rods to hold the head of a snail, so that the snail discharged from the upper end of the spiral plate 21 continues to move towards the rear end of the double guide rod 3 with the snail head held between the two guide rods and the snail tail pointing vertically downward. The double guide rod 3 has an arc-shaped transition section 31 at the front end to screen out snails with head sizes smaller than the strip-shaped gap 200 and to guide the snails to line up in a row. The double guide rod 3 has a straight working section 32 at the rear end to guide the snails to line up in a row so that the snail tail separation device can separate the snail tail.

[0050] The screw head pressure plate 4 is fixedly installed on the upper end of the working section 32 of the double guide rod 3 and is set parallel to the working section 32 of the double guide rod 3. It is used to press down the head of the snail from above to maintain the stability of the snail when performing the snail tail cutting and separation operation.

[0051] The snail tail detachment device is located at the lower end of the working section 32 of the double guide rod 3, and is used to detach the snail tails of the snails arranged on the double guide rod 3.

[0052] The screw tail disconnection device includes a screw tail cutting mechanism and a screw tail breaking mechanism. The screw tail cutting mechanism and the screw tail breaking mechanism are respectively located at the lower end of the working section 32 of the double guide rod 3. The screw tail cutting mechanism is relatively close to the front end of the two guide rods, and it cuts into or cuts off the screw tail with a disc-shaped cutter. The screw tail breaking mechanism is relatively close to the rear end of the two guide rods, and it breaks off the screw tail with a multi-blade cutter.

[0053] The screw-tail cutting mechanism includes a bracket A51, a motor A52, and a disc-shaped cutter 53. One end of the bracket A51 is directly or indirectly fixedly connected to the vibrating base 1, and the other end extends out from the lower end of the working section 32 of the double guide rod 3. The motor A52 is fixedly mounted on the bracket A51, with its shaft extending vertically upward. The disc-shaped cutter 53 is disc-shaped, with a mounting hole A at its center. It is horizontally fixedly mounted on the shaft of the motor A52 through the mounting hole A and is located at the lower end of the working section 32 of the double guide rod 3. The cutting edge of the disc-shaped cutter 53 is located on the outer edge of the disc shape.

[0054] The screw tail breaking mechanism includes a bracket B61, a motor B62, and a multi-blade cutter 63. One end of the bracket B61 is directly or indirectly fixedly connected to the vibrating base 1, and the other end extends out from the lower end of the working section 32 of the double guide rod 3. The motor B62 is fixedly mounted on the bracket B61, with its shaft extending vertically upward. The multi-blade cutter 63 includes a central sleeve and multiple blades fixedly connected to the outer circumferential surface of the central sleeve and evenly distributed in a ring. It is horizontally fixedly mounted on the shaft of the motor B62 through the central sleeve and located at the lower end of the working section 32 of the double guide rod 3. The cutting edge of the multi-blade cutter 63 is located on one or both edges of each blade.

[0055] Preferably, the multi-bladed cutter 63 of the screw tail breaking mechanism is arranged at the same height as or 0-2mm lower than the disc-shaped cutter 53 of the thread cutting mechanism, thereby ensuring that the screw tail is broken off only at the cutting point.

[0056] Preferably, there are multiple sets of screw tail cutting mechanisms, all arranged sequentially along the extension direction of the working section 32 of the double guide rods 3. The disc cutters 53 of each screw tail cutting mechanism are arranged at the same height. In the double guide rods 3, the guide rod relatively closer to the screw conveyor is defined as the inner guide rod 33, and the guide rod relatively farther from the screw conveyor is defined as the outer guide rod 34. All screw tail cutting mechanisms are arranged at the lower end of the outer guide rod 34, and in the direction from the front end to the rear end of the two guide rods, the circular area swept by the disc cutter 53 in each screw tail cutting mechanism gradually approaches the inner guide rod 33, thereby increasing the cutting depth of each screw tail cutting mechanism sequentially. Correspondingly, there is only one set of screw tail breaking mechanisms. The circular area swept by the multi-blade cutter 63 in the screw tail breaking mechanism is closer to the inner guide rod 33 than the circular area swept by the disc cutter 53 in the nearest screw tail cutting mechanism.

[0057] Preferably, the batch snail tail removal device also includes a feeding hood (not shown in the figure). The feeding hood is fixedly connected to the upper end of the base 1 and covers the screw conveyor 2 inside. The upper end of the feeding hood is provided with a funnel-shaped depression, and a discharge hole is provided at the center of the depression. The snails placed in the depression slide down to the discharge hole under the action of gravity, enter the inside of the feeding hood through the discharge hole, and fall on the conical surface 11.

[0058] Preferably, the batch snail tail removal device further includes a moving assembly (not shown in the figure), with at least three sets of moving assemblies evenly distributed in a ring on the outer wall of the lower part 12; the moving assembly includes a wheel seat and universal wheels mounted on the wheel seat, the wheel seat being movably mounted on the outer wall of the lower part 12 and being able to rotate and switch between a horizontal and a vertical posture (the wheel seat structure that can rotate and switch between two positions is a common prior art, and the detailed structure will not be described in detail); when all the wheel seats in the moving assembly are rotated to a horizontal posture, the wheel seats and universal wheels extend radially outward from the lower part 12, and all the universal wheels do not contact the ground, and the lower part 12 is directly supported on the ground; when all the wheel seats in the moving assembly are rotated to a vertical posture, the wheel seats and universal wheels extend axially downward from the lower part 12, and all the universal wheels simultaneously contact the ground, thereby making the batch snail tail removal device movable.

[0059] Briefly describe the working principle of Embodiment 1 of this utility model:

[0060] Step 1. Gathering and feeding: Pour the snails to be processed onto the conical surface 11. After starting the vibration motor, the conical surface 11 will generate high-frequency micro-amplitude vibration. Under the combined action of vibration inertia and gravity, the snails will roll and gather towards the outer edge of the conical surface 11, and finally concentrate at the outer edge of the conical surface 11 (i.e., the connection between the conical surface 11 and the spiral plate 21).

[0061] Step 2. Spiral Lifting: Since the lower end of the spiral plate 21 is fixed at the lowest point of the outer periphery of the cone surface 11, the snails gathered there can be directly captured, allowing the snails to enter the lower end of the spiral path. Then, under the action of vibration, the snails are transported upward along the spiral path. When the snails are transported to the upper outlet of the spiral plate, they enter the transition section 31 of the double guide rod 3. During the transport process, since the spiral radius of the spiral plate 21 gradually increases from bottom to top, the spacing between the snails automatically increases during the upward process, avoiding accumulation.

[0062] Step 3. Screening and Positioning: The strip gap 200 of the transition section 31 of the double guide rods 3 allows snails that are too small to fall directly and not get stuck between the two guide rods. Snails of the correct size are guided into a single row. Snails of the correct size enter the working section 32 of the double guide rods with their heads stuck in the strip gap of the double guide rods and their tails hanging downwards. In the working section 32 of the double guide rods 3, the snail head pressure plate presses down on the snail head from above, forming a stable state of "limiting on both sides + constraining from above".

[0063] Step 4. Progressive cutting: As the snail moves along the working section 32 of the double guide rod 3, it passes through the disc-shaped cutter 53 of multiple sets of snail tail cutting mechanisms in sequence. The first set of snail tail cutting mechanisms cuts into the snail tail relatively shallowly (about 20%). As the installation positions of the subsequent sets of snail tail cutting mechanisms gradually approach the inner guide rod 33, the cutting depth increases sequentially (up to 80%). The multi-bladed cutter 63 of the snail tail breaking mechanism is aligned with the snail tail cut or rotates at high speed 0-2mm below the cut. Its blades completely sever the remaining tissue with high-frequency shearing force. The snail with the snail tail removed is discharged from the rear end of the two guide rods. Example 2

[0064] like Figure 13-15 As shown, the only difference between this embodiment and embodiment 1 is that the screw tail disconnection device includes two oppositely arranged screw tail pressure bars 71 and a reciprocating drive mechanism for driving the two screw tail pressure bars 71 to move synchronously towards each other or synchronously away from each other.

[0065] The reciprocating drive mechanism includes a bracket C72, a motor C73, a lead screw 74, and guide rods 75. One end of the bracket C72 is directly or indirectly fixedly connected to the vibration base 1, and the other end extends out from the lower end of the working section 32 of the double guide rods 3. The motor C73 is fixedly mounted on the bracket C72. One end of the lead screw 74 is mounted on the bracket C72 through a first bearing, and the other end is connected to the shaft of the motor C73 through a coupling. The two ends of the lead screw 74 are respectively provided with a first thread section 741 and a second thread section 742 with opposite thread directions. The guide rods 75 are mounted on the bracket C72 through second bearings at both ends. There are two guide rods 75, which are parallel to each other and arranged horizontally. Both guide rods 75 are parallel to the lead screw 74. One of the screw tail pressure strips 71 is provided with a first threaded hole that mates with the first threaded section 741 of the lead screw 74, and the other screw tail pressure strip 71 is provided with a second threaded hole that mates with the second threaded section 742 of the lead screw 74. Both screw tail pressure strips 71 are provided with a through hole for the guide rod 75 to slide through.

[0066] A threaded tail pressure strip 71 with a first threaded hole is threadedly connected to the first threaded section of the lead screw 74 through the first threaded hole, and slides with two guide rods 75 through two through-rod holes. A threaded tail pressure strip 71 with a second threaded hole is threadedly connected to the second threaded section of the lead screw 74 through the second threaded hole, and slides with two guide rods 75 through two through-rod holes.

[0067] Briefly describe the working principle of Embodiment 2 of this utility model:

[0068] The working principle of Example 2 is the same as that of Example 1, with the first three steps being the same, and only the fourth step being different.

[0069] Step 4. Crushing the snail tails: When the snails move along the working section 32 of the double guide rod 3 to between the two snail tail pressing strips 71, the motor C73 starts, driving the lead screw 74 to rotate clockwise, causing the two snail tail pressing strips 71 to move synchronously towards each other. When the two snail tail pressing strips 71 move close together, the snail tails of the row of snails are crushed simultaneously. The motor C72 starts, driving the lead screw 74 to rotate counterclockwise, causing the two snail tail pressing strips 71 to move synchronously away from each other, forming a space for the snails to enter between the two snail tail pressing strips 71. This process is repeated, with the two snail tail pressing strips 71 repeating the process of "moving towards each other - moving close together - moving away from each other - opening up", thus removing the snail tails.

The motor B is fixedly mounted on the bracket B, with its shaft extending vertically upward. The multi-blade cutter includes a central sleeve and multiple blades fixedly connected to the outer circumference of the central sleeve and evenly distributed in a ring. The blades are horizontally fixedly mounted on the shaft of the motor B through the central sleeve and are located at the lower end of the double guide rod working section. The cutting edge of the multi-blade cutter is located on one or both edges of each blade.

7. The batch snail tail removal device as described in claim 6, characterized in that: There are multiple sets of screw tail cutting mechanisms, all arranged sequentially along the extension direction of the double guide rod working section. The disc cutters of each screw tail cutting mechanism are arranged at the same height. In the double guide rods, the guide rod relatively closer to the screw conveyor is defined as the inner guide rod, and the guide rod relatively farther from the screw conveyor is defined as the outer guide rod. All screw tail cutting mechanisms are arranged at the lower end of the outer guide rod, and in the direction from the front end to the rear end of the two guide rods, the circular area swept by the disc cutter in each screw tail cutting mechanism gradually approaches the inner guide rod, thereby increasing the cutting depth of each screw tail cutting mechanism. Correspondingly, there is one set of screw tail breaking mechanisms. The circular area swept by the multi-blade cutter in the screw tail breaking mechanism is closer to the inner guide rod than the circular area swept by the disc cutter in the nearest screw tail cutting mechanism.

8. The batch snail tail removal device as described in claim 3, characterized in that: The screw tail disconnection device includes two oppositely arranged screw tail pressure bars and a reciprocating drive mechanism for driving the two screw tail pressure bars to move synchronously towards each other or synchronously away from each other. The reciprocating drive mechanism includes a bracket C, a motor C, a lead screw, and guide rods. One end of the bracket C is directly or indirectly fixedly connected to the vibration base, and the other end extends out from the lower end of the working section of the double guide rods. The motor C is fixedly mounted on the bracket C. One end of the lead screw is mounted on the bracket C through a first bearing, and the other end is connected to the shaft of the motor C through a coupling. The two ends of the lead screw are respectively provided with a first thread section and a second thread section with opposite thread directions. The guide rods are mounted on the bracket C through second bearings at both ends. There are two guide rods, which are parallel to each other and arranged horizontally. Both guide rods are parallel to the lead screw. One of the screw tail pressure strips is provided with a first threaded hole that mates with the first threaded section of the lead screw, and the other screw tail pressure strip is provided with a second threaded hole that mates with the second threaded section of the lead screw. Both screw tail pressure strips are provided with through holes for the guide rods to slide through. A screw tail pressure strip with a first threaded hole is threadedly connected to the first threaded section of the lead screw through the first threaded hole, and slides with two guide rods through two through rod holes; a screw tail pressure strip with a second threaded hole is threadedly connected to the second threaded section of the lead screw through the second threaded hole, and slides with two guide rods through two through rod holes.
