DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1:

[0033] like Figures 1 to 10 As shown, a sorting device for processing snails according to an embodiment of the present invention comprises a base frame 1, a sorting bucket 2 slidably arranged at one end of the top of the base frame 1, a feeding pipe 3 connected and fixed to one end of the top of the sorting bucket 2, a plurality of sealing doors 4 installed at one end of the outer peripheral surface of the sorting bucket 2, and a multi-stage sorting and drying mechanism for sorting snails;

[0034] The multi-stage sorting and drying mechanism includes a screening component and an air blowing component;

[0035] When it is necessary to sort the batches of snails according to their sizes, the batches of snails are put into the inner cavity of the sorting barrel 2 through the feeding pipe 3, and the snails of different sizes can be sorted through the screening component, so that the snails in different size ranges can be at different heights, and the snails at different heights can be taken out by opening the sealing door 4. In this process, the blowing component can ensure that the interior of the sorting barrel 2 will not be overly moist, thereby preventing excessive moisture residue from promoting the decomposition of snail protein to produce low-level amines, thereby improving the processing effect of the snails.

[0036] like Figures 1 to 10As shown in the figure, the screening component includes a rotating rod 7 rotatably connected to the middle position inside the sorting barrel 2, a sleeve disk 6 sleeved on the outer peripheral surface of the rotating rod 7 at multiple positions, multiple groups of filter holes 11 evenly formed through the surface of the sleeve disk 6 and arranged in an equidistant surrounding manner, a diversion component arranged on the surface of the sleeve disk 6, a vertical movement component acting on the sleeve disk 6, a support rod 22 slidably inserted through both sides inside the sorting barrel 2, a connecting plate 23 fixed to the extension of the support rod 22 outside the sorting barrel 2, a spring 24 sleeved on the outer peripheral surface of the support rod 22 outside the base frame 1, and a damper 25 fixed to the bottom of the connecting plate 23. One end of the spring 24 is fixed to the surface of the adjacent connecting plate 23, and the other end of the spring 24 is fixed to the surface of the top of the sorting barrel 2. The bottom of the damper 25 is fixed to the surface of the top of the sorting barrel 2. The pore diameters of the multiple groups of filter holes 11 gradually decrease from top to bottom. The support rod 22 is fixed to the inner walls of multiple sleeve disks 6;

[0037] When the field snails enter the inside of the sorting barrel 2, the rotating rod 7 is rotated to make the sleeve disk 6 reciprocate vertically while rotating under the action of the vertical movement component, so that the field snails can be screened under the acting force of the movement of the sleeve disk 6. Field snails within different size ranges can be located on the tops of multiple different sleeve disks 6 under the screening action of multiple groups of filter holes 11 with different pore diameters. Sediments, broken shells and other impurities will be left below the sleeve disk 6 at the bottom of the inside of the sorting barrel 2. The separated water can be discharged through the drain pipe at the bottom of one side of the outer peripheral surface of the sorting barrel 2. When the sealing door 4 is opened, multiple portions of screened field snails and impurities can be recycled. When the sleeve disk 6 reciprocates vertically, when the sleeve disk 6 moves vertically upward, it can drive the support rod 22 to move upward, so that the adjacent spring 24 deforms. Thus, under the action of the resilience of the spring 24, it can assist the sleeve disk 6 to reset after moving upward, which helps the sleeve disk 6 to move more stably during the vertical reciprocating movement process. The damper 25 can reduce the swinging amplitude of the sleeve disk 6 caused by external forces and improve the stability of the sleeve disk 6.

[0038] As Figures 1 to 10 shown in the figure, the diversion component includes multiple first guide grooves 10 evenly formed through the top surface of the sleeve disk 6 near the filter holes 11 and arranged in an equidistant surrounding manner, and multiple second guide grooves 12 with different diameters formed through the top of the sleeve disk 6. The first guide grooves 10 are connected to the inside of the adjacent filter holes 11, and the second guide grooves 12 are connected to a group of adjacent filter holes 11. Multiple convex particles are evenly fixed on the surfaces of the first guide grooves 10 and the second guide grooves 12;

[0039] Through the settings of the first guiding groove 10 and the second guiding groove 12, when the sleeve disc 6 rotates, under the action of centrifugal force, it can guide the field snails to roll towards the direction of the filtering holes 11, extend the screening path, improve the screening efficiency, reduce the accumulation of the field snails that can pass through the sieve, and through the setting of the raised particles, it can enhance the friction force, prompt the attitude adjustment of the field snails to improve the screening accuracy.

[0040] As Figures 1 to 10 shown, the vertical movement component includes a movable shaft 13 rotatably connected to one side position of the outer peripheral surface of the sorting barrel 2, a rotating shaft 14 rotatably connected through the inner wall of the sorting barrel 2 near the movable shaft 13, a first bevel gear 15 fixedly sleeved on the outer peripheral surface of the movable shaft 13 and extending to the outside of the sorting barrel 2 on the outer peripheral surface of the rotating shaft 14, a cam 16 fixedly sleeved on the outer peripheral surface of the rotating shaft 14 inside the sorting barrel 2, a resisting groove 8 opened on the outer peripheral surface of the rotating rod 7 near the sleeve disc 6 at the adjacent position, and a resisting block 9 inserted into the inside of the resisting groove 8. One side of the resisting block 9 is fixed to the inner wall of the sleeve disc 6 at the adjacent position, and the two adjacent first bevel gears 15 are meshed with each other;

[0041] When the movable shaft 13 rotates, it can drive a set of first bevel gears 15 to rotate. Thus, under the meshing action between the two adjacent first bevel gears 15, the other set of first bevel gears 15 drives the rotating shaft 14 to rotate, so that a plurality of cams 16 can rotate synchronously. Thus, under the action of gravity and the resisting action of the cams 16 on the sleeve disc 6 at the adjacent position, the cams 16 can start to resist the sleeve disc 6. And because the resisting block 9 can only move vertically along the inner cavity of the resisting groove 8 at the adjacent position, it can limit the movement track of the sleeve disc 6. When the rotating rod 7 rotates, the sleeve disc 6 can rotate synchronously under the resisting action between the inner wall of the resisting groove 8 and the resisting block 9. And in this process, the sleeve disc 6 can make a reciprocating movement in the vertical direction under the resisting action of the cams 16, and under the resilience of the spring 24, it can assist the sleeve disc 6 to move more smoothly when making a reciprocating movement in the vertical direction.

[0042] As Figures 1 to 10As shown, the screening assembly also includes a driving component acting on the sorting barrel 2, and the driving component includes a motor 5 fixed to the bottom of the base frame 1, a second rotating disk 44 fixed to the top of the output end of the motor 5, a support frame 45 fitted on the top of the second rotating disk 44, a connecting shaft 46 inserted in the inner cavity of the support frame 45, a rotating shaft 17 rotatably connected to one end of the top of the sorting barrel 2, a rotating rod 7 fixedly sleeved at the upper and lower ends of the outer circumference of the sorting barrel 2, and an outer circumference of the second guide groove 12 located at the top of the first bevel gear 15 and the outer circumference of the rotating shaft 17. The pulley 18 at the bottom of the surface, the connecting belt 19 sleeved between the two pulleys 18 at the same horizontal height, the circular gear 20 fixedly sleeved at the middle position of the outer circumference of the rotating shaft 17, and the rack 21 fixed on the surface of the sorting barrel 2 near the circular gear 20, the rack 21 and the circular gear 20 are meshed and connected, the bottom of the connecting shaft 46 is fixed to the surface of the second rotating disk 44, the two ends of the top of the support frame 45 are fixed to the surface of the bottom of the sorting barrel 2, and the output end of the motor 5 is rotatably connected to the inner wall of the base frame 1;

[0043] When the motor 5 is started, the second rotating disk 44 can be rotated, so that the connecting shaft 46 can make a circular motion, so that the sorting bucket 2 can make a reciprocating motion in the horizontal direction under the resistance effect of the connecting shaft 46 on the inner wall of the support frame 45 and the connection and limitation effect of the sorting bucket 2 and the base frame 1, so that the sorting bucket 2 can increase the horizontal screening force on the snails entering the sorting bucket 2, break the single jumping mode of the snails during pure vertical vibration under the action of the vertical moving component, form a spiral or parabolic motion trajectory, accelerate the particle separation speed, and the horizontal shear force can effectively peel off the wet mud and sand adhering to the surface of the snails, cooperate with the rotating sleeve 6, so that the self-cleaning rate of the filter hole 11 is improved, thereby improving the screening efficiency of the snails and shortening the time required for screening. At the same time, when the sorting bucket 2 makes a reciprocating motion in the horizontal direction, the rotating shaft 17 can rotate under the meshing effect between the rack 21 and the circular gear 20, so that the rotating rod 7 and the movable shaft 13 can rotate synchronously under the connection effect of the two sets of pulleys 18 and the connecting belt 19.

[0044] like Figures 1 to 10As shown in the figure, the air blowing assembly includes an annular tube 29 arranged at the top of the sleeve plate 6, a connecting tube 30 connected and fixed to one side of the support rod 22, a connecting cylinder 26 connected and fixed to one side of the connecting tube 30, a connecting cylinder 26 fixed to one side of the base frame 1, a first piston rod 27 slidably inserted into the inner cavity of the connecting cylinder 26, a first air inlet pipe 40 connected and fixed to the bottom of the connecting cylinder 26, a plurality of heaters 32 arranged at equal intervals and circumferentially around the inner cavity of the annular tube 29, and a plurality of air outlet pipes 31 arranged at equal intervals and circumferentially around the bottom of the annular tube 29. The connecting tube 30 is fixedly connected through the side wall of the sorting barrel 2. One side of the first piston rod 27 passes through the adjacent connecting cylinder 26 and is fixed to the surface of the adjacent fixing seat 28;

[0045] By turning on the heater 32, the temperature in the inner cavity of the annular tube 29 is heated to maintain at 30 degrees Celsius. A one-way valve and a filter are fixed in the inner cavity of the first air inlet pipe 40, and a one-way valve is fixed at the connection between the connecting cylinder 26 and the connecting tube 30. The filter is provided to prevent external dust from entering the inner cavity of the adjacent connecting cylinder 26. And due to the one-way valve in the first air inlet pipe 40, the air inside the connecting cylinder 26 cannot be discharged from the first air inlet pipe 40, but the outside air can enter the inside of the connecting cylinder 26 through the first air inlet pipe 40. The one-way valve at the connection between the connecting cylinder 26 and the connecting tube 30 allows air to be transported only from the connecting cylinder 26 to the connecting tube 30;

[0046] When the sorting barrel 2 moves horizontally in a reciprocating motion, it drives the connecting cylinder 26 to move horizontally in a reciprocating motion. Thus, due to the arrangement of the first piston rod 27, the air pressure in the inner cavity of the connecting cylinder 26 changes. When the sorting barrel 2 moves to the left, it can transport the outside air from the first air inlet pipe 40 to the inner cavity of the connecting cylinder 26. When the sorting barrel 2 moves to the right, the air flow in the inner cavity of the connecting cylinder 26 can be transported to the connecting tube 30. Under this action, the air pressure in the inner cavity of the annular tube 29 changes, so that the air inside the annular tube 29 is discharged from the plurality of air outlet pipes 31. And since the air flow discharged from the air outlet pipes 31 is about 30 degrees Celsius, it uniformly dries the field snails placed on the top of the sleeve plate 6, thereby preventing excessive moisture from existing in the field snails piled up on the top of the sleeve plate 6 and avoiding the promotion of the decomposition of field snail protein to produce low-grade amine substances due to the residual excessive moisture.

[0047] Embodiment 2:

[0048] In the above method, although it solves the problem that the efficiency of manually sorting field snails is low, and the field snails in the sorting stage are often washed. If the environment where the field snails are located is too humid during sorting, excessive water residue promotes the decomposition of proteins to produce low-grade amines, which may combine with nitrites to form the carcinogen nitrosamine, affecting the edible safety of field snails. However, in reality, only the air flow discharged from the annular pipe 29 is difficult to evenly dry the field snails piled on the top of the sleeve plate 6, and it is easy to bring impurities such as sediment into the inside of the contact groove 8 under the action of the air flow, hindering the reciprocating movement of the sleeve plate 6 in the vertical direction.

[0049] Therefore, as Figures 8 to 9 shown, compared with the first embodiment, another embodiment of the present invention is as follows:

[0050] As Figures 1 to 10 shown, the blowing assembly further includes an anti-blocking component. The anti-blocking component includes a movable seat 33 slidably disposed on the top of the base frame 1, a rotating rod 34 rotatably connected to the surface of the movable seat 33, a second bevel gear 35 fixedly sleeved on the outer peripheral surface of the top of the rotating shaft 17 and one end of the outer peripheral surface of the movable frame 36, a first rotating disk 38 fixed to the other end of the rotating rod 34, a movable frame 36 disposed at one end of the first rotating disk 38, a contact shaft 39 inserted into the inner cavity of the movable frame 36, and a second piston rod 37 fixed to the bottom of the contact shaft 39. The two second bevel gears 35 are meshed with each other. One end of the contact shaft 39 is fixed to the surface of the first rotating disk 38, and one end of the bottom of the movable seat 33 is fixed to the surface of the sorting barrel 2;

[0051] When the sorting barrel 2 reciprocates in the horizontal direction, it can drive the movable seat 33 to reciprocate in the horizontal direction. During this process, under the meshing action of the two second bevel gears 35, the rotating rod 34 rotates, thereby driving the first rotating disk 38 to rotate, so that the contact shaft 39 makes a circular motion, and under the contact action of the contact shaft 39 on the inner wall of the movable frame 36, the movable frame 36 can drive the second piston rod 37 to reciprocate in the vertical direction.

[0052] As Figures 1 to 10 shown, the anti-blocking component further includes a cylindrical groove 41 opened at the top of the inner cavity of the rotating rod 7, a second intake pipe 43 fixed at a position on one side of the rotating rod 7, and a gas guiding groove 42 communicating with the bottom of the cylindrical groove 41. The gas guiding groove 42 is communicated with a plurality of contact grooves 8. The second intake pipe 43 is communicated with the inner cavity of the cylindrical groove 41. The second piston rod 37 is slidably connected to the inner wall of the rotating rod 7;

[0053] By fixing a filter screen and a one-way valve inside the second air inlet pipe 43, fixing a one-way valve on the top of the inner wall of the air guide groove 42, and fixing a filter screen at the connection between the air guide groove 42 and the abutment groove 8, the filter screen is set to prevent external dust from entering the inner cavity of the barrel groove 41, and the impurities separated from the snails in the inner cavity of the sorting barrel 2 under the screening effect enter the inner cavity of the air guide groove 42. The one-way valve is set so that the second air inlet pipe 43 can only intake air into the barrel groove 41, and the barrel groove 41 can only intake air into the inner cavity of the air guide groove 42, so that the second piston rod 37 and the inner cavity of the barrel groove 41 can make reciprocating motion. When the second piston rod 37 moves, the air pressure in the inner cavity of the barrel groove 41 can change, so that when the second piston rod 37 moves downward, the air pressure in the inner cavity of the barrel groove 41 can change, so that the air flow enters the air guide groove 42 and is discharged from the resistance groove 8, so that under the action of the air flow, the inside of the resistance groove 8 can be prevented from being blocked by impurities and the snails accumulated on the top of the sleeve disc 6 can be radially dried, thereby improving the drying effect of the snails, and the second piston rod 37 can suck the outside air into the inner cavity of the barrel groove 41 when it moves downward, and the rest of the air will be transported to the inner cavity of the air guide groove 42 when the second piston rod 37 moves downward again.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
