Description

Technical Field

[0001] The present invention belongs to the field of snail mucus extraction, and specifically relates to a snail mucus extraction device and method. Background Art

[0002] The mucus secreted by snails contains natural allantoin, calcium, glycolic acid, collagen, protein, vitamins, etc., which are essential materials for making cosmetics. In the prior art, such as SIMONE in Italy, by placing snails in a hemispherical cabin with constant temperature and humidity, and then spraying a mild acidic solution to cause the snails to release mucus as a defense mechanism, and then quickly extracting the snail mucus. Compared with killing snails to extract mucus, this method is more conducive to cyclic extraction of snail mucus, and to a certain extent reduces the cost of mucus extraction;

[0003] However, even a mild acidic solution will kill some snails. Most of these dead snails are concentrated on the bottom surface of the hemispherical cabin. The fundamental reason is that a large number of snails are piled up together, and the snails at the bottom cannot move. As the acidic solution mixes with the snail mucus accumulating at the bottom, the snails at the bottom are continuously stimulated by the acidic solution and cannot breathe in the acidic solution mixed with snail mucus for a long time and thus suffocate. The means for extracting snail mucus while maintaining its activity still need to be improved. Summary of the Invention

[0007] Preferably, the mucus collection cabin includes a frustum-shaped block fixedly installed on the outer wall surface of the cylindrical block. A cylindrical outer shell is fixedly installed on the outer wall surface of the frustum-shaped block. An annular seal cover is installed between the top surfaces of the cylindrical outer shell and the cylindrical block. The hemispherical cabin cover is installed on the top surface of the cylindrical block.

[0008] Preferably, a plurality of liquid discharge holes are evenly arranged between the side wall surfaces of the frustum-shaped block and the cylindrical block, and a second water valve communicating with the inner cavity is installed on the outer side of the cylindrical outer shell.

[0009] Preferably, the mucus scraping mechanism includes a motor installed in the middle of the inner cavity of the control base. A shaft rod is fixedly installed at the rotating end of the motor. The upper end of the shaft rod penetrates through the middle of the upper end of the second water valve, and a second arc-shaped scraper is installed. A first arc-shaped scraper is installed on the outer side wall surface of the shaft rod below the second arc-shaped scraper.

[0010] Preferably, the outer side wall surface of the second arc-shaped scraper is attached to the inner side wall surface of the hemispherical hatch cover, and the inner side wall surface of the first arc-shaped scraper is attached to the outer side wall surface of the hemispherical insulating cover.

A plurality of water seepage holes are evenly arranged on the annular sliding plate. A limiting rod is fixedly installed in the middle of the annular sliding plate. An annular internal thread block is installed in the middle of the limiting rod. The limiting rod is slidably arranged in the sliding cavity.

[0012] Preferably, the snail ventilation component further includes a thread groove opened on the outer wall surface of the lower end of the shaft rod. The annular internal thread block is threadedly installed with the thread groove. Limiting rings are fixedly installed on the outer wall surfaces of the upper and lower ends of the shaft rod at the thread groove. The limiting rings are rotatably arranged in the inner cavity of the spherical platform mounting seat.

[0013] Preferably, the electric shock head is composed of a cylindrical conductive head, a cylindrical insulating head, and a columnar conductive head. The cylindrical insulating head is arranged on the inner side wall surface of the cylindrical conductive head, and the columnar conductive head is arranged on the inner side wall surface of the cylindrical insulating head.

[0014] An extraction method for a snail mucus extraction device, the method includes the following operation steps:

[0015] Step S1: Mechanically screen out snails with similar size specifications, and then manually pick out the dead and poorly viable snails from the mechanically screened snails;

[0016] Step S2: Put the live snails after manual picking into an incubator and fast them for one to five days. After the fasting period ends, feed them with a feed rich in polysaccharides and mucoproteins for one to five days to promote the mucus secretion during extraction;

[0017] Step S3: After the feeding period ends, pretreat the outer shell of the snails with a mild bactericide to reduce the risk of microbial contamination, and then wash the snails with clean water to remove impurities;

[0018] Step S4: Open the hemispherical hatch cover, evenly lay the disinfected and cleaned snails on the surface of the annular slide plate, that is, in the extraction groove formed by the cylindrical block and the spherical platform mount. After placing, inject clean water at an appropriate temperature into the extraction groove, with the water injection height lower than the top of the snail shell, and then close the hemispherical hatch cover;

[0019] Step S5: Stand still and observe for a period of time until the snails start to climb from the clean water to the inner wall surface of the hemispherical hatch cover and the outer surface of the hemispherical insulating cover;

[0020] For the snails crawling on the surface of the hemispherical insulating cover, output an equal voltage to a number of electric shock heads simultaneously through the hemispherical power supply block, and instantaneously stimulate the feet of the snails two to four times to prompt the foot glands to secrete mucus;

[0021] For the snails crawling on the inner wall surface of the hemispherical hatch cover, after the snails on the surface of the hemispherical insulating cover are stimulated by electric shock, slowly rotate the motor to drive the second arc-shaped scraper to rotate on the inner wall surface of the hemispherical hatch cover, so as to scrape the snails from the inner wall surface of the hemispherical hatch cover, making them fall back into the extraction groove formed by the cylindrical block and the spherical platform mount again, and scrape the snail mucus attached to the inner wall surface of the hemispherical hatch cover through the second arc-shaped scraper, which is convenient for the snails to climb onto the inner wall surface of the hemispherical hatch cover again to secrete mucus and collect the mucus in time, avoiding the mucus losing its activity;

[0022] While the second arc-shaped scraper rotates, the first arc-shaped scraper rotates accordingly to scrape the snails on the surface of the hemispherical insulating cover and scrape the snail mucus attached to the surface of the hemispherical insulating cover, and its purpose is the same as above;

[0023] Step S6: For the snails in the extraction groove formed by the cylindrical block and the spherical platform mount, to avoid the situation that some snails climb on their counterparts due to being far from the water surface, resulting in excessive load on the counterparts below them and being unable to crawl away from the water surface and then drowning, during the rotation of the shaft rod, the limit rod, the annular internal thread block and the thread groove cooperate to drive the annular slide plate to rise to the water surface height, and seep water through the water seepage holes on the annular slide plate, so that the snails on the annular slide plate can breathe, thereby reducing the mortality rate of the snails in the clean water. After the shaft rod rotates in the reverse direction to drive the annular slide plate to reset, use clean water to gently stimulate the snails again to prompt them to secrete mucus;

[0024] Step S7: After the mucus of the snails is extracted, put them back into the breeding pond and supplement clean water and concentrated feed. After several days, it can be extracted again to improve the utilization rate.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, a snail is placed in an extraction groove formed by a cylindrical block and a spherical table mounting seat, and clear water at an appropriate temperature is injected into the extraction groove. Since the snail lacks oxygen after staying in the water for a long time, it will actively crawl out of the water and crawl on the surface of the hemispherical insulating cover, and then simultaneously output an equal voltage to a number of electric shock heads through the hemispherical power supply block, instantly stimulating the snail's foot two to four times, prompting the foot gland to secrete mucus.

[0027] 2. In the present invention, the motor slowly rotates to drive the second arc-shaped scraper to rotate on the inner wall surface of the hemispherical hatch cover, scraping the snails crawling on the inner wall surface of the hemispherical hatch cover, so that they fall back into the extraction groove again, and scraping the snail mucus attached to the inner wall surface of the hemispherical hatch cover by the second arc-shaped scraper, facilitating the snails to climb onto the inner wall surface of the hemispherical hatch cover again to secrete mucus and collecting the mucus in a timely manner, avoiding the mucus losing its activity.

[0028] 3. In the present invention, during the rotation of the shaft rod, the limiting rod, the annular internal threaded block and the threaded groove cooperate to drive the annular slide plate to rise to the water surface height, and water seeps through the water seepage holes on the annular slide plate, enabling the snails on the annular slide plate to breathe, thereby reducing the mortality rate of the snails in the clear water. After the shaft rod rotates in the reverse direction to drive the annular slide plate to reset, the clear water is used again to gently stimulate the snails, prompting them to secrete mucus.

[0045] The following further describes the implementation mode of the present invention in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0046] Embodiment 1:

[0047] Refer to Att Figure 1 to Att Figure 8 As shown, a snail mucus extraction device includes a control base 1. A mucus extraction chamber 2 is installed on the top surface of the control base 1. A mucus collection chamber 3 is installed outside the mucus extraction chamber 2. A mucus scraping mechanism 4 is installed in the middle of the mucus extraction chamber 2. A snail ventilation component 5 is installed between the mucus extraction chamber 2 and the mucus collection chamber 3;

[0048] The mucus extraction chamber 2 includes a circular base 201 and a hemispherical hatch 210. In the middle of the circular base 201, a spherical platform mounting seat 202 is fixedly installed. On the top surface of the spherical platform mounting seat 202, a hemispherical power supply block 203 is fixedly installed. A number of electric shock heads 204 are evenly installed on the hemispherical power supply block 203. A hemispherical insulating cover 205 is fixedly installed outside the hemispherical power supply block 203. Electric shock holes 206 for matching the use of the electric shock heads 204 are opened on the hemispherical insulating cover 205. A cylindrical block 207 is fixedly installed on the top surface of the circular base 201. A water inlet hole 208 is opened on the circular base 201. A first water valve 209 is installed at the bottom of the water inlet hole 208;

[0049] As can be seen from the above, open the hemispherical hatch 210, and evenly lay the disinfected and cleaned snails on the surface of the annular slide plate 501, that is, in the extraction groove formed by the cylindrical block 207 and the spherical platform mounting seat 202. After placing them, inject clean water at an appropriate temperature into the extraction groove, and the water injection height is lower than the top of the snail shell. Close the hemispherical hatch 210 to carry out the extraction work;

[0050] Since the snails will lack oxygen after staying in water for a long time and will actively crawl out of the water, they will crawl on the inner wall surface of the hemispherical hatch 210 and the outer wall surface of the hemispherical insulating cover 205 to secrete mucus. The hemispherical power supply block 203 provides an equal voltage to a number of electric shock heads 204 thereon, so that the feet of the snails crawling on the hemispherical insulating cover 205 are stimulated, and then their foot glands secrete mucus;

[0051] It should be specially noted above that a number of electric shock heads 204 are connected in parallel with the internal power supply module of the hemispherical power supply block 203, and the power supply module is connected with a control module, and the control module is used to control the power supply frequency and duration of the power supply module.

[0052] Embodiment 2:

[0053] Refer to Appendix Figure 1 to Appendix Figure 8 As shown, the mucus collection chamber 3 includes a frustum-shaped block 301 fixedly installed on the outer wall surface of the cylindrical block 207. A cylindrical outer shell 302 is fixedly installed on the outer wall surface of the frustum-shaped block 301. An annular seal 303 is installed between the top surfaces of the cylindrical outer shell 302 and the cylindrical block 207. The hemispherical hatch 210 is installed on the top surface of the cylindrical block 207;

[0054] A number of drain holes 304 are evenly opened between the side wall surfaces of the frustum-shaped block 301 and the cylindrical block 207. A second water valve 305 communicating with the inner cavity is installed on the outer side of the cylindrical outer shell 302;

[0055] Through a number of liquid discharge holes 304 evenly arranged between the side wall surfaces of the frustum-shaped block 301 and the cylindrical block 207, the liquid level height after the mixing of clear water and mucus during the extraction process is restricted, so that when the liquid level reaches the set height of the liquid discharge holes 304, it enters the inner cavity formed by the frustum-shaped block 301 and the cylindrical outer shell 302 through the liquid discharge holes 304, and quickly accumulates in the inner cavity along the inclined surface of the frustum-shaped block 301, and then is discharged through the second water valve 305 and thus collected, avoiding the influence of too high liquid level on the survival of snails.

[0056] Embodiment Three:

[0057] Refer to Att Figure 1 to Att Figure 8 As shown, the mucus scraping mechanism 4 includes a motor 401 installed in the middle of the inner cavity of the control base 1. The rotating end of the motor 401 is fixedly installed with a shaft rod 402. The upper end of the shaft rod 402 penetrates through the upper end of the second water valve 305 and a second arc-shaped scraper 404 is installed in the middle. A first arc-shaped scraper 403 is installed on the outer side wall surface of the shaft rod 402 below the second arc-shaped scraper 404;

[0058] The outer side wall surface of the second arc-shaped scraper 404 is arranged in a fitting manner with the inner side wall surface of the hemispherical hatch cover 210, and the inner side wall surface of the first arc-shaped scraper 403 is arranged in a fitting manner with the outer side wall surface of the hemispherical insulating cover 205;

[0059] As can be seen from the above, for the snails crawling on the inner wall surface of the hemispherical hatch cover 210, after the snails on the surface of the hemispherical insulating cover 205 are stimulated by electric shock, the motor 401 slowly rotates to drive the second arc-shaped scraper 404 to rotate on the inner wall surface of the hemispherical hatch cover 210, and then the snails are scraped off from the inner wall surface of the hemispherical hatch cover 210, so that they fall into the extraction groove formed by the cylindrical block 207 and the spherical platform mounting seat 202 again, and the second arc-shaped scraper 404 scrapes the snail mucus adhering to the inner wall surface of the hemispherical hatch cover 210;

[0060] While the second arc-shaped scraper 404 rotates, the first arc-shaped scraper 403 rotates accordingly, scraping the snails on the surface of the hemispherical insulating cover 205 and scraping the snail mucus adhering to the surface of the hemispherical insulating cover 205, and its purpose is the same as above.

[0061] Embodiment Four:

[0062] Refer to Att Figure 1 to Att Figure 8As shown in the figure, the snail air exchange component 5 includes an annular sliding plate 501 arranged on the top surface of the circular base 201 and a sliding cavity 507 opened in the middle of the spherical table mounting seat 202. Water seepage holes 502 are evenly distributed on the annular sliding plate 501. A limiting rod 503 is fixedly installed in the middle of the annular sliding plate 501. An annular internal thread block 504 is installed in the middle of the limiting rod 503. The limiting rod 503 is slidably arranged in the sliding cavity 507;

[0063] The snail air exchange component 5 further includes a thread groove 505 opened on the outer wall surface of the lower end of the shaft rod 402. The annular internal thread block 504 is threadedly installed with the thread groove 505. Limiting rings 506 are fixedly installed on the outer wall surfaces of the shaft rod 402 at the upper and lower ends of the thread groove 505. The limiting rings 506 are rotatably arranged in the inner cavity of the spherical table mounting seat 202;

[0064] As can be seen from the above, during the rotation of the shaft rod 402, the limiting rod 503, the annular internal thread block 504 and the thread groove 505 cooperate to drive the annular sliding plate 501 to rise to the water surface height, and water seepage is carried out through the water seepage holes 502 on the annular sliding plate 501, so that the snails located on the annular sliding plate 501 can breathe;

[0065] The electric shock head 204 is composed of a cylindrical conductive head 2041, a cylindrical insulating head 2042 and a columnar conductive head 2043. The cylindrical insulating head 2042 is arranged on the inner wall surface of the cylindrical conductive head 2041. The columnar conductive head 2043 is arranged on the inner wall surface of the cylindrical insulating head 2042;

[0066] As can be seen from the above, when the snail's foot contacts the cylindrical conductive head 2041 and the columnar conductive head 2043 at the same time, the voltage provided by the hemispherical power supply block 203 will stimulate the snail's foot, thereby causing it to secrete mucus.

[0067] An extraction method of a snail mucus extraction device, the method includes the following operation steps:

[0068] Step S1: Mechanically screen out snails with similar size specifications, and then manually pick out the dead and poorly viable snails from the mechanically screened snails;

[0069] Step S2: Put the freshly picked snails into an incubator and fast them for one to five days. After the fasting period ends, feed them with a feed rich in polysaccharides and mucoproteins [such as agaric, okra, natto] for one to five days to promote the mucus secretion during extraction;

[0070] Step S3: After the feeding period ends, pretreat the snail shell with a mild bactericide [such as benzalkonium chloride, etc.] to reduce the risk of microbial contamination, and then wash the snails with clean water to remove impurities;

[0071] Step S4: Open the hemispherical hatch 210, evenly lay the disinfected and cleaned snails on the surface of the annular slide 501, that is, in the extraction groove formed by the cylindrical block 207 and the spherical platform mount 202. After placing them, inject clean water at an appropriate temperature into the extraction groove, with the water injection height lower than the top of the snail shell, and then close the hemispherical hatch 210;

[0072] Step S5: Let it stand and observe for a period of time until the snails start to climb from the clean water to the inner wall surface of the hemispherical hatch 210 and the outer surface of the hemispherical insulating cover 205 [Since the snails are short of oxygen after staying in the water for a long time, they will actively crawl out of the water. During this process, they will secrete mucus into the water. Initially, putting the snails into the water can be understood as a mild stimulation, which can prompt them to actively crawl and secrete mucus];

[0073] For the snails crawling on the surface of the hemispherical insulating cover 205, output equal voltage to a number of electric shock heads 204 simultaneously through the hemispherical power supply block 203, and instantaneously stimulate the snail feet two to four times to prompt the foot glands to secrete mucus;

[0074] For the snails crawling on the inner wall surface of the hemispherical hatch 210, after the snails on the surface of the hemispherical insulating cover 205 are stimulated by electric shock, drive the second arc-shaped scraper 404 to rotate on the inner wall surface of the hemispherical hatch 210 through the slow rotation of the motor 401, so as to scrape the snails off the inner wall surface of the hemispherical hatch 210, making them fall back into the extraction groove formed by the cylindrical block 207 and the spherical platform mount 202 again, and scrape the snail mucus attached to the inner wall surface of the hemispherical hatch 210 through the second arc-shaped scraper 404, which is convenient for the snails to climb onto the inner wall surface of the hemispherical hatch 210 again to secrete mucus and collect the mucus in time, to avoid the mucus losing its activity;

[0075] While the second arc-shaped scraper 404 is rotating, the first arc-shaped scraper 403 rotates accordingly to scrape the snails on the surface of the hemispherical insulating cover 205 and scrape the snail mucus attached to the surface of the hemispherical insulating cover 205, and its purpose is the same as above;

[0076] Step S6: For the snails in the extraction groove formed by the cylindrical block 207 and the spherical platform mount 202, in order to avoid the situation that some snails climb on their peers due to being far away from the water surface, resulting in excessive load on the peers below them and being unable to crawl away from the water surface and then drowning, during the rotation of the shaft rod 402, the limit rod 503, the annular internal thread block 504 and the thread groove 505 cooperate to drive the annular slide 501 to rise to the water surface height, and water seeps through the water seepage holes 502 on the annular slide 501, enabling the snails on the annular slide 501 to breathe, thereby reducing the mortality rate of the snails in the clean water. After the shaft rod 402 rotates in the reverse direction to drive the annular slide 501 to reset, use clean water to gently stimulate the snails again to prompt them to secrete mucus;

[0077] Step S7: After the mucus of the snail is extracted, put it back into the breeding pond and supplement clean water and concentrated feed. After several days, it can be extracted again to improve the utilization rate.

The extraction method of a snail mucus extraction device according to any one of claims 1 to 8, characterized in that, This method includes the following operation steps: Step S1: Mechanically screen out snails with similar size specifications, and then manually pick out the dead and poorly active snails from the mechanically screened snails; Step S2: Put the fresh snails after manual picking into an incubator and fast them for one to five days. After the fasting period ends, feed them with feed rich in polysaccharides and mucoproteins for one to five days to promote the secretion of mucus during extraction; Step S3: After the feeding period ends, pretreat the shells of the snails with a mild fungicide to reduce the risk of microbial contamination, and then wash the snails with clean water to remove impurities; Step S4: Open the hemispherical hatch (210), evenly lay the disinfected and washed snails on the surface of the annular slide plate (501), that is, in the extraction groove formed by the cylindrical block (207) and the spherical table mounting seat (202). After placing them, inject clean water at an appropriate temperature into the extraction groove, and the water injection height is lower than the top of the snail shell. Then close the hemispherical hatch (210); Step S5: Stand still and observe for a period of time until the snails start to climb from the clean water to the inner wall surface of the hemispherical hatch (210) and the outer surface of the hemispherical insulating cover (205); For the snails crawling on the surface of the hemispherical insulating cover (205), simultaneously output an equal voltage to a plurality of electric shock heads (204) through the hemispherical power supply block (203), and instantaneously stimulate the feet of the snails two to four times to prompt the foot glands to secrete mucus; For the snails crawling on the inner wall surface of the hemispherical hatch cover (210), after the snails on the surface of the hemispherical insulating cover (205) are stimulated by electric shock, the motor (401) slowly rotates to drive the second arc-shaped scraper (404) to rotate on the inner wall surface of the hemispherical hatch cover (210), thereby scraping the snails from the inner wall surface of the hemispherical hatch cover (210) and making them fall back into the extraction groove formed by the cylindrical block (207) and the spherical platform mounting seat (202). And the second arc-shaped scraper (404) scrapes the snail mucus adhering to the inner wall surface of the hemispherical hatch cover (210), which is convenient for the snails to climb onto the inner wall surface of the hemispherical hatch cover (210) again to secrete mucus and collect the mucus in time, avoiding the loss of activity of the mucus; While the second arc-shaped scraper (404) rotates, the first arc-shaped scraper (403) rotates accordingly to scrape the snails on the surface of the hemispherical insulating cover (205) and scrape the snail mucus adhering to the surface of the hemispherical insulating cover (205), and its purpose is the same as above; Step S6: For the snails in the extraction groove formed by the cylindrical block (207) and the spherical platform mounting seat (202), to avoid the situation that some snails climb onto their counterparts due to being far from the water surface, resulting in excessive load on the counterparts below them and being unable to crawl away from the water surface and then drowning, during the rotation of the shaft rod (402), the limiting rod (503), the annular internal thread block (504) and the thread groove (505) cooperate to drive the annular sliding plate (501) to rise to the water surface height, and water seeps through the water seepage holes (502) on the annular sliding plate (501), enabling the snails on the annular sliding plate (501) to breathe, thereby reducing the mortality rate of the snails in the clear water. And after the shaft rod (402) rotates in the reverse direction to drive the annular sliding plate (501) to reset, the snails are gently stimulated again with clear water to prompt them to secrete mucus; Step S7: After the mucus of the snails is extracted, put them back into the breeding pond to supplement clear water and concentrated feed. After several days, the extraction can be carried out again to improve the utilization rate.
