Description

Technical Field

[0001] The utility model relates to the technical field of field snail tail-removing equipment, in particular to a field snail tail-removing device. Background Art

[0002] The river snail is an ovoviviparous animal, scientifically known as the Chinese round river snail, which is widely distributed in freshwater lakes, reservoirs, rice fields, ponds and ditches across my country. It has become one of the most popular aquatic products because of its tender, delicious and nutritious meat. However, the snail meat grows inside the shell. Before cooking, the tail of the shell needs to be cut off or pliers removed to make the front and back of the snail transparent, making it easier for people to suck the snail meat.

[0003] However, in the prior art, one method is to use scissors or pliers to cut or clamp the snails manually, which is inefficient. Since the snails are small in size, it is difficult for human hands to hold them, making it difficult to cut or clamp the snails, especially for snails with thick shells. Long-term work can easily cause finger wear. Another method is a large industrial drum-type tail-removing device, which uses centrifugal force to cut with a blade, which has a complex structure principle, is difficult to operate, and occupies a large space.

[0004] Therefore, it is urgent to propose a snail tail removing device to solve the above problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] The snail tail removing device provided in this embodiment has strong universality, simple operation, strong cutting force, labor-saving hands, high work efficiency, simple structure, small footprint, and is suitable for household use.

[0034] Specific as Figure 1As shown, the snail tailing device includes a middle shell 100, a cover plate 200, a cutting blade 300 and a driving member 400. The cover plate 200 is covered on the top opening of the middle shell 100, and a plurality of through holes 201 of different sizes are arranged on the cover plate 200 with the center of the cover plate 200 as the center of the circle. The tail of the snail can penetrate the through hole 201 of corresponding size and extend into the middle shell 100, so that the snail is stuck in the cover plate 200, which solves the problem that the snail is not easy to hold with the hand, and makes the operation simple. Through holes 201 of different sizes can be suitable for snails of different sizes, which improves the universality of the snail tailing device. The cutting blade 300 is located in the middle shell 100, the driving member 400 is fixed to the bottom of the middle shell 100, and the output end of the driving member 400 is penetrated in the middle shell 100 and connected with the cutting blade 300 to drive the cutting blade 300 to rotate, so as to realize the semi-automaticity of the snail tailing device and improve the work efficiency. By screwing the cover plate 200 around the axis of the middle shell 100, the tail of the snail can be moved toward the direction close to the cutting blade 300 until it is in vertical contact with the blade of the cutting blade 300 and cut off. Compared with cutting the tail of the snail with a manual pliers or other tools, the snail tail removal device semi-automatically cuts the snail tail by screwing the cover plate 200 and the motor driving the cutting blade 300 to rotate, which saves hand effort and has a strong cutting force, and can remove the tail of the snail with a thicker shell. Compared with a large industrial rolling tail removal device, the snail tail removal device can remove the snail's tail only by screwing the cover plate 200 to drive the snail close to the rotating cutting blade 300. The operation is simple, and the snail tail removal device has a simple structure and a small size, which is suitable for home use.

[0035] Since the cover plate 200 is disposed on the top of the middle shell 100 and can rotate on the middle shell 100, in order to ensure the rotation stability of the cover plate 200, the cover plate 200 needs to be positioned on the rotation axis. Figure 1 and Figure 2 As shown, a support column 110 is vertically provided at the center of the bottom wall of the middle shell 100, a slot body 210 is provided at the center of the inner wall of the cover plate 200, and the other end of the support column 110 is inserted into the slot body 210, and the cover plate 200 can rotate around the support column 110. When installing the cover plate 200, the slot body 210 of the cover plate 200 is buckled into the support column 110, and the installation positioning of the cover plate 200 can be achieved. The support column 110 can also support the cover plate 200 and serve as the rotation axis of the cover plate 200 during the rotation process of the cover plate 200.

[0036] In this embodiment, the middle shell 100 is a cylindrical shell, and the cover plate 200 is circular. The groove body 210 is an annular boss on the inner wall of the middle shell 100 , and the upper end of the support column 110 can be inserted into the groove body 210 .

[0037] Furthermore, in order to reduce the friction between the cover plate 200 and the top opening edge of the middle shell 100 and thereby make screwing the cover plate 200 more labor-saving, a plurality of protrusions 220 are distributed circumferentially on the inner wall of the cover plate 200 , and the protrusions 220 abut against the top opening edge of the middle shell 100 .

[0038] In order to increase the snap-fit ​​installation effect and rotational positioning effect between the cover plate 200 and the middle shell 100, a snap-fit ​​edge is provided along the circumference of the cover plate 200 so that the cover plate 200 is snap-fitted and installed to the middle shell 100, the inner wall of the snap-fit ​​edge contacts the outer wall of the middle shell 100, and the inner wall of the cover plate 200 abuts against the top opening edge of the middle shell 100.

[0039] Since the cover plate 200 is provided with through holes 201 of different sizes, the snails to be tailed need to be placed in the through holes 201 of corresponding sizes. When the cover plate 200 with the snails is placed on the middle shell 100, the through holes 201 with the snails should be placed close to the position of the cutting blade 300 in the middle shell 100, so that the tail of the snail can be cut off by twisting the cover plate 200 at a relatively small angle. In order to facilitate finding the corresponding position of the assembly of the cover plate 200 and the middle shell 100, the upper end of the outer wall of the middle shell 100 is provided with a first score line 120, and the outer wall of the cover plate 200 is provided with a plurality of second score lines 230 corresponding to the through holes 201 one by one, so that when the cover plate 200 is placed on the middle shell 100, the second score lines 230 corresponding to the through holes 201 with the snails can be aligned with the first score lines 120.

[0040] In this embodiment, both the first score line 120 and the second score line 230 may be narrow strip-shaped gaps.

[0041] In this embodiment, the number of the through holes 201 is four, and of course it can also be two, three, five, six, etc., which is not specifically limited in the present invention.

[0042] In view of the shape of the tail of the field snail, preferably, the shape of the through hole 201 is circular.

[0043] In order to limit the rotation angle of the cover plate 200, a first limiting column 140 is also vertically provided on the bottom wall of the middle shell 100, and a plurality of limiting ribs 240 are arranged in a circle centered on the inner wall of the cover plate 200 with the center of the cover plate 200 as the center. The plurality of limiting ribs 240 and the plurality of through holes 201 are alternately arranged, and the other end of the first limiting column 140 is located between the corresponding two adjacent limiting ribs 240 and close to one of the limiting ribs 240, so that when the cover plate 200 is screwed to remove the tail of the snail, the first limiting column 140 blocks the other limiting rib 240 to limit the rotation angle of the cover plate 200.

[0044] In this embodiment, the limiting rib 240 is a strip plate structure, which is circumferentially arranged along the outer wall of the annular boss and radially extends along the annular boss.

[0045] In order to reset the cover plate 200 after rotation, the snail tail removing device further comprises an elastic member (not shown in the figure), one end of the elastic member is connected to the cover plate 200, and the other end is connected to the middle shell 100, and the elastic member enables the cover plate 200 to rotate and reset.

[0046] From the perspective of cost saving, the elastic part can be a spring, which is sleeved on the outer wall of the support column 110. One end of the spring is connected to the inner wall of the cover plate 200, and the other end is connected to the bottom wall of the middle shell 100. When the cover plate 200 is screwed, the spring is twisted. After the hand is released, the spring returns to its original position and pulls the cover plate 200 back.

[0047] In this embodiment, the snail tail removal device further includes a second limiting column 150, which is located at the bottom wall of the middle shell 100. When the cover plate 200 is covered on the middle shell 100, the corresponding limiting rib 240 is located between the first limiting column 140 and the second limiting column 150; the elastic member is a special-shaped spring, which is sleeved on the outer wall of the support column 110, and one end of the spring is connected to the end of the support column 110 close to the cover plate 200, and the other end is deformed and abuts against the side of the second limiting column 150 away from the first limiting column 140 and connected to the cover plate 200 (the end of the spring is pulled until the bottom of the second limiting column 150 and then bends upward to connect the cover plate 200), and the cover plate 200 is screwed, the spring generates torsion, the spring abutting against the second limiting column 150 leaves the second limiting column 150, and the spring returns until the deformed end of the spring returns to the second limiting column 150, that is, the second limiting column 150 limits the return position of the spring.

[0048] Furthermore, in order to facilitate the connection between the special-shaped spring and the support column 110, a narrow groove parallel to the axis of the support column 110 is provided on the outer wall of the support column 110, and the end of the special-shaped spring is clamped in the above-mentioned narrow groove.

[0049] Usually, after the snail tailing device is used for a period of time, the inside of the middle shell 100 needs to be cleaned. Although the body of the driving member 400 is located outside the middle shell 100, the output end of the driving member 400 passes through the middle shell 100, and the output end of the driving member 400 needs to be waterproofed.

[0050] Optionally, a waterproof platform 130 is provided on the inner wall of the bottom of the middle housing 100, and the output end of the driver 400 passes through the middle housing 100 and the waterproof platform 130 in sequence and is connected to the cutting blade 300. That is, the waterproof platform 130 is mounted on the outside of the output end of the driver 400 like a waterproof cover for waterproofing.

[0051] In this embodiment, the waterproof platform 130 is conical, which facilitates water to flow down along the waterproof platform 130 and prevents residues on the waterproof platform 130 from being easily washed away.

[0052] Furthermore, the snail tail removal device also includes a sealing ring (not shown in the figure), which is sleeved on the output end of the driving member 400 and located between the cutting blade 300 and the waterproof platform 130. The sealing ring can seal the periphery of the perforation of the output end of the driving member 400 on the waterproof platform 130, thereby improving the waterproof performance of the middle shell 100 and avoiding damage to the driving member 400. Furthermore, in order to facilitate the discharge of the cleaning waste water, a waste outlet 101 is provided at the bottom of the side wall of the middle shell 100, and the bottom center of the middle shell 100 is raised toward the direction close to the cover plate 200, so as to avoid the accumulation of cleaning waste water at the bottom of the middle shell 100, and facilitate the cleaning waste water to flow to the edges around the bottom wall of the middle shell 100, and then be discharged from the waste outlet 101.

[0053] In this embodiment, the driving member 400 is a motor, and the output shaft of the motor passes through the middle housing 100 and is connected to the cutting blade 300. The snail tail removal device also includes a mounting plate, and the output shaft of the motor passes through the mounting plate and the middle housing 100 in sequence, and the mounting plate abuts against the outer bottom wall of the middle housing 100 and the end of the motor.

[0054] Furthermore, if Figure 3 and Figure 4 As shown, the cutting blade 300 is connected to the output shaft of the motor through two nuts, that is, the two nuts are sleeved on the output shaft of the motor and are located on the upper and lower sides of the cutting blade 300 to fix the cutting blade 300.

[0055] like Figure 1 and Figure 5 As shown, the snail tail removing device further includes a bottom shell 500 located below the middle shell 100 , the body of the driving member 400 is located in the bottom shell 500 , and the bottom shell 500 protects the driving member 400 .

[0056] In this embodiment, the bottom shell 500 is circular, and a through hole 501 is provided at the bottom of the bottom shell 500 near the center of the bottom shell 500. If the cleaning sewage in the middle shell 100 enters the middle shell 100, the cleaning sewage can be discharged from the through hole 501.

[0057] In order to discharge the cleaning wastewater, the bottom of the bottom case 500 is concave downward.

[0058] A suction cup 510 is also provided on the outer bottom wall of the bottom shell 500, and the suction cup 510 can be used to fix the snail tail removing device after it is moved.

[0059] It should be noted that the snail tail-removing device in this embodiment is only used to demonstrate the connection relationship and position relationship among the various components of the snail tail-removing device, and does not mean that the snail tail-removing device in the present invention can only be placed vertically, that is, vertical. In other embodiments, the snail tail-removing device can also be arranged horizontally, that is, horizontal. The present invention does not specifically limit the setting orientation of the snail tail-removing device.

[0060] The operation steps of the snail tail removal device are as follows:

[0061] S1: Place the snail to be tailed into the through hole 201 of corresponding size (with the snail tail facing downward), and the snail is stuck on the cover plate 200;

[0062] S2: snap the cover plate 200 onto the middle shell 100, so that the annular boss on the cover plate 200 is snapped onto the support column 110, and the first engraved line 120 corresponding to the through hole 201 containing the snail is aligned with the second engraved line 230 on the middle shell 100;

[0063] S3: The snail tailing device is powered on, the driving member 400 is started, and the cutting blade 300 rotates;

[0064] S4: Rotate the cover plate 200 toward the cutting blade 300 (in this embodiment, the cover plate 200 is rotated counterclockwise) until it cannot be rotated any more;

[0065] S5: The snails are finished with tails removed.

[0066] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
