Description

Technical Field

[0001] The invention belongs to the field of field snail processing, in particular to a sorting device for field snail processing. Background Art

[0002] Snail processing is the process of converting fresh snails into ready-to-eat foods or semi-finished products through systematic process processing. The core of the process lies in desilting, grading and sorting, seasoning and ripening, and fresh-keeping packaging.

[0003] Since the size of the snails is different, the deliciousness of their meat is also different, so the snails of different sizes need to be classified according to different eating methods. Manual sorting of snails is inefficient, and the snails are often cleaned during the sorting stage. If the environment in which the snails are located is too humid during sorting, excessive residual water promotes protein decomposition to produce low-level amines, which combine with possible nitrites to form carcinogens such as nitrosamines, affecting the safety of snails and making them unsuitable for use.

DETAILED DESCRIPTION

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

[0032] Example 1:

[0033] like Figures 1 to 10 As shown, a sorting device for processing snails according to an embodiment of the present invention includes 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 circumference 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 batches of snails according to size, 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. During 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 amine substances, thereby improving the processing effect of the snails.

[0036] like Figures 1 to 10As shown, the screening assembly includes a rotating rod 7 rotatably connected to the middle position of the inner cavity of the sorting barrel 2, a sleeve disc 6 sleeved at multiple positions on the outer circumference of the rotating rod 7, a plurality of groups of filter holes 11 uniformly penetrated and arranged in an equidistant and surrounding manner on the surface of the sleeve disc 6, a flow guide component arranged on the surface of the sleeve disc 6, a vertical moving component acting on the sleeve disc 6, a support rod 22 slidably inserted at positions on both sides of the inner cavity of the sorting barrel 2, a connecting plate 23 fixed to the support rod 22 and extending outside the sorting barrel 2, a spring 24 sleeved on the outer circumference of the support rod 22 and located outside the sorting barrel 2, 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 connecting plate 23 at an adjacent position, 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 apertures of the plurality of groups of filter holes 11 gradually decrease from top to bottom, and the support rod 22 is fixed to the inner walls of the plurality of sleeve discs 6;

[0037] When the snails enter the inner cavity of the sorting barrel 2, the rotating rod 7 is used to rotate the disc 6 under the action of the vertical moving assembly, so that the disc 6 can rotate and reciprocate in the vertical direction, so that the snails can be screened under the action of the movement of the disc 6. Snails in different size ranges can be screened by multiple groups of filter holes 11 with different apertures so that they are placed on the top of multiple different discs 6. Impurities such as mud, sand and broken shells are left below the disc 6 at the bottom of the inner cavity of the sorting barrel 2, and the separated water can be discharged through the drainage pipe at the bottom of one side of the outer peripheral surface of the sorting barrel 2. When the sealing door 4 is opened, the screened snails and impurities can be recovered. When the sleeve disc 6 reciprocates in the vertical direction, the sleeve disc 6 can drive the support rod 22 to move upward when it moves vertically upward, thereby causing the spring 24 at the adjacent position to deform. Under the action of the rebound force of the spring 24, the sleeve disc 6 can be assisted to reset after moving upward, thereby helping the sleeve disc 6 to make the reciprocating motion in the vertical direction more stable. The damper 25 can reduce the swing amplitude of the sleeve disc 6 caused by external force, thereby improving the stability of the sleeve disc 6.

[0038] like Figures 1 to 10 As shown, the flow guide component includes a plurality of first guide grooves 10 that are equidistantly distributed and arranged near the filter holes 11 on the top surface of the sleeve 6, and a plurality of second guide grooves 12 with different diameters that are opened on the top of the sleeve 6. The first guide grooves 10 are connected to the interior of the filter holes 11 at adjacent positions, and the second guide grooves 12 are connected to a group of filter holes 11 at adjacent positions. A plurality of protruding particles are evenly fixed on the surfaces of the first guide grooves 10 and the second guide grooves 12.

[0039] By setting the first guide groove 10 and the second guide groove 12, the snails can be guided to roll toward the filter hole 11 under the action of centrifugal force when the sleeve 6 rotates, thereby extending the screening path, improving the screening efficiency, and reducing the accumulation of snails that can pass through the screen. The setting of the raised particles can enhance the friction force, prompting the snails to adjust their posture to improve the screening accuracy.

[0040] like Figures 1 to 10 As shown, the vertical moving component includes a movable shaft 13 rotatably connected to a position on one side of the outer circumference of the sorting barrel 2, a rotating shaft 14 that penetrates and rotatably connects to the inner wall of the sorting barrel 2 near a position on one side of the movable shaft 13, a first bevel gear 15 fixedly sleeved on the outer circumference of the movable shaft 13 and the outer circumference of the rotating shaft 14 extending to the outside of the sorting barrel 2, a cam 16 fixedly sleeved on the outer circumference of the rotating shaft 14 and located inside the sorting barrel 2, a resistance groove 8 provided on the outer circumference of the rotating rod 7 near the position of the adjacent sleeve disc 6, and a resistance block 9 inserted into the resistance groove 8, one side of the resistance block 9 is fixed to the inner wall of the adjacent sleeve disc 6, and the two adjacent first bevel gears 15 are meshedly connected;

[0041] When the movable shaft 13 rotates, it can drive a group of first bevel gears 15 to rotate, so that under the meshing action of the two adjacent first bevel gears 15, another group of first bevel gears 15 drives the rotating shaft 14 to rotate, so that multiple cams 16 can rotate synchronously, so that under the action of gravity and the resistance of the cam 16 to the adjacent position sleeve 6, the cam 16 can start the resistance action on the sleeve 6, and because the resistance block 9 can only move in the vertical direction in the inner cavity of the adjacent position resistance groove 8, it can limit the movement trajectory of the sleeve 6. At the same time, when the rotating rod 7 rotates, the sleeve 6 can be rotated synchronously under the resistance action of the inner wall of the resistance groove 8 and the resistance block 9, and in this process, the sleeve 6 can make reciprocating motion in the vertical direction under the resistance action of the cam 16, and under the action of the rebound force of the spring 24, it can assist the sleeve 6 to make reciprocating motion in the vertical direction more stable.

[0042] like Figures 1 to 10As shown, the screening assembly also includes a driving component that acts on the sorting bucket 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 into the inner cavity of the support frame 45, a rotating shaft 17 rotatably connected to one end of the top of the sorting bucket 2, a rotating rod 7 fixedly sleeved at the upper and lower ends of the outer circumference of the sorting bucket 2, and an outer circumference of the movable shaft 13 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 to the surface of the base 1 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 bucket 2, and the output end of the motor 5 is rotatably connected to the inner wall of the base 1;

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

[0044] like Figures 1 to 10As shown, the blowing assembly includes an annular tube 29 arranged on the top of the sleeve 6, a connecting tube 30 connected and fixed to one side of the annular tube 29, a connecting cylinder 26 connected and fixed to one side of the connecting tube 30, a fixing seat 28 fixed to one side of the base frame 1, a first piston rod 27 slidably inserted in 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 fixed to the inner cavity of the annular tube 29 and arranged in an equidistant and surrounding manner, and a plurality of air outlet pipes 31 connected and fixed to the bottom of the annular tube 29 and arranged in an equidistant and surrounding manner. The connecting tube 30 is fixedly connected to one side of the inner wall of the sorting barrel 2 in a penetrating manner, and one side of the first piston rod 27 passes through the connecting cylinder 26 at an adjacent position and is fixed to the surface of the fixing seat 28 at an adjacent position.

[0045] The temperature of the inner cavity of the annular tube 29 is heated by turning on the heater 32 so as to be maintained 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 pipe 30. The filter prevents external dust from entering the inner cavity of the adjacent connecting cylinder 26. In addition, due to the setting of the one-way valve inside 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 interior 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 pipe 30 allows air to be transported only from the connecting cylinder 26 to the connecting pipe 30.

[0046] When the sorting barrel 2 makes a reciprocating motion in the horizontal direction, it drives the connecting cylinder 26 to make a reciprocating motion in the horizontal direction, so that the air pressure in the inner cavity of the connecting cylinder 26 changes under the setting of the first piston rod 27. The sorting barrel 2 moves to the left to transport the outside air from the first air inlet pipe 40 to the inner cavity of the connecting cylinder 26. The sorting barrel 2 moves to the right so that the airflow in the inner cavity of the connecting cylinder 26 can be transported to the connecting pipe 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 multiple air outlet pipes 31, and since the airflow discharged from the air outlet pipes 31 is at about 30 degrees Celsius, the snails placed on the top of the sleeve 6 are evenly dried, thereby preventing the snails accumulated on the top of the sleeve 6 from having too much moisture, and avoiding the residual excessive moisture from promoting the decomposition of snail protein to produce low-level amine substances.

[0047] Example 2:

[0048] Although the above method solves the problem that the efficiency of manual sorting of snails is low and the snails are often washed during the sorting stage, if the environment in which the snails are located is too humid during sorting, excessive residual moisture promotes protein decomposition to produce low-level amines, which combine with possible nitrites to form carcinogen nitrosamines, affecting the safety of eating snails, but from a practical point of view, it is difficult to evenly dry the snails accumulated on the top of the sleeve 6 only by the airflow discharged from the annular tube 29, and it is easy for impurities such as mud and sand to be brought into the interior of the conflict groove 8 under the action of the airflow, hindering the reciprocating motion of the sleeve 6 in the vertical direction.

[0049] Therefore Figures 8 and 9 As shown in Comparative Example 1, another embodiment of the present invention is:

[0050] like Figures 1 to 10 As shown, the blowing assembly also includes an anti-blocking component, which includes a movable seat 33 slidably arranged on the top of the base 1, a rotating rod 34 rotatably connected to the surface of the movable seat 33, a second bevel gear 35 fixedly sleeved on the top of the outer circumference of the rotating shaft 17 and one end of the outer circumference of the rotating rod 34, a first rotating disk 38 fixed to the other end of the rotating rod 34, a movable frame 36 provided at one end of the first rotating disk 38, an interference shaft 39 inserted into the inner cavity of the movable frame 36 and a second piston rod 37 fixed to the bottom of the movable frame 36, the two second bevel gears 35 are meshedly connected, one end of the interference 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 bucket 2;

[0051] When the sorting bucket 2 reciprocates in the horizontal direction, it can drive the movable seat 33 to reciprocate in the horizontal direction. In this process, the rotating rod 34 rotates under the meshing action between the two second bevel gears 35, thereby driving the first rotating disk 38 to rotate, thereby causing the interference shaft 39 to perform circular motion, and under the interference action of the interference 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] like Figures 1 to 10 As shown, the anti-blocking component also includes a cylindrical groove 41 opened at the top of the inner cavity of the rotating rod 7, a second air inlet pipe 43 fixed at a position on one side of the rotating rod 7, and an air guide groove 42 connected to the bottom of the cylindrical groove 41. The air guide groove 42 is connected to the multiple interference grooves 8. The second air inlet pipe 43 is connected to 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 conflict groove 8, the setting of the filter screen prevents 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 interior of the air guide groove 42. The setting of the one-way valve makes it possible for the second air inlet pipe 43 to only intake air into the barrel groove 41, and the barrel groove 41 to 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 dried radially, thereby improving the drying effect of the snails. When the second piston rod 37 moves downward, the outside air can be sucked into the inner cavity of the barrel groove 41, and the second piston rod 37 will be transported to the inner cavity of the air guide groove 42 when it moves downward again.
