Description

Technical Field

[0001] The present invention belongs to the technical field of snail cleaning, and specifically relates to a snail processing device. Background Art

[0002] During the snail processing, cleaning is one of the crucial steps. Sediments, algae, microorganisms and other impurities often adhere to the surface of snails. If the cleaning is not thorough, it will not only affect the subsequent processing efficiency and product quality, but also pose potential health hazards to consumers.

[0003] For example, in the publicly disclosed patent: CN222217065U, a snail cleaning device, which has a simple steel structure frame and some equipped electric control components. The snails are rotated and stirred in a round basin filled with snails by a stirring brush, driving the snails to rotate in the water flow and rub against each other in the round basin, so as to rub off the moss attached to the snail shells. According to the attachment situation, more than 90% of the moss dirt can be cleaned within a short time. The stirring and cleaning mechanism is set to be telescopic and can be applied to round basins of different sizes within a certain range.

[0004] In the above patent, a rotating and stirring mechanism that can be applied to round basins of different sizes is set to clean the snails. However, when the snails are rotated and rubbed for cleaning, although the surface of the snails can be cleaned, the dirt washed off will still remain in the water body. Therefore, after taking out the snails, the dirt in the water body will still adhere to the surface of the snails, thus reducing the cleaning effect of the snails.

Specific embodiments

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0037] As Figures 1 to 10 shown, in an embodiment of the present invention, a snail processing device is described. A cleaning barrel 32 is arranged inside a cleaning box 1, and a stirring frame 36 for stirring snails is rotatably installed inside the cleaning barrel 32;

[0038] The bottom end of the cleaning barrel 32 is arranged as a conical platform, and a water leakage hole is opened on the conical platform;

[0039] A circulation pump 3 is arranged on the side wall of the cleaning box 1. The suction end of the circulation pump 3 is communicated with the cleaning box 1 through a water suction pipe, and the output end of the circulation pump 3 is connected with a spray head through a water outlet pipe 4 and faces the inside of the cleaning barrel 32;

[0040] A re-washing box 31 is arranged on one side of the cleaning box 1. A transfer cylinder 33 is fixedly installed inside the cleaning barrel 32. One end of the transfer cylinder 33 is bent and faces the inside of the re-washing box 31. A delivery auger 40 is rotatably installed inside the transfer cylinder 33;

[0041] Inside the cleaning box 1, a filter plate 2 is provided, and the filter plate 2 is arranged below the cleaning bucket 32.

[0042] The top of the cleaning bucket 32 is open, and the snails to be cleaned can be placed inside the cleaning bucket 32. Under the action of the circulation pump 3, water enters the water outlet pipe 4 and is discharged from the nozzle, and the water is sprayed inside the cleaning bucket 32 to spray the snails to be cleaned. Subsequently, by rotating the stirring frame 36, the snails are rotated inside the cleaning bucket 32, and the snails can be effectively pre-cleaned. The impurities washed off from the snails will be discharged through the leakage holes on the conical table. At this time, the filter plate 2 provided inside the cleaning box 1 can filter the mixture of water and impurities, thereby ensuring the use efficiency of the circulating water. The pre-cleaned snails can be conveyed to the inside of the re-washing box 31 through the transfer cylinder 33 under the action of the delivery auger 40 to complete the secondary cleaning. There is clear water stored inside the re-washing box 31 for soaking the pre-cleaned snails.

[0043] As a preferred embodiment of the present invention, a driving motor 39 is fixedly installed on the cleaning bucket 32. The output shaft of the driving motor 39 is fixedly installed with a transmission gear 34. A toothed ring 35 meshing with the transmission gear 34 is rotatably installed on the cleaning bucket 32, and the toothed ring 35 is fixedly connected to the stirring frame 36.

[0044] By starting the driving motor 39, the transmission gear 34 can be driven to rotate, and at the same time, the toothed ring 35 can be driven to rotate, so as to realize the rotation of the stirring frame 36 inside the cleaning bucket 32.

[0045] As a preferred embodiment of the present invention, a driving wheel 37 is fixedly installed at the top of the transmission gear 34, and a driven wheel 38 is fixedly installed at the output end of the delivery auger 40. The driving wheel 37 and the driven wheel 38 are connected by a belt.

[0046] While the transmission gear 34 is rotating, the driving wheel 37 can be driven to rotate. Through the belt, the driven wheel 38 can be driven to rotate to realize the control of the delivery auger 40. When pre-cleaning the snails inside the cleaning bucket 32, the delivery auger 40 is controlled to rotate counterclockwise by the driving motor 39. When the snails are pre-cleaned, by rotating the driving motor 39 clockwise, the delivery auger 40 can be controlled to convey the snails in the cleaning bucket 32 to the inside of the re-washing box 31 through the transfer cylinder 33 for soaking and cleaning. By pre-cleaning and soaking and cleaning the snails, the cleaning efficiency of the snails can be further improved.

[0047] As a preferred embodiment of the present invention, a cleaning plate 6 is slidably installed at the top of the filter plate 2, and an auxiliary plate 5 is slidably installed at the bottom of the filter plate 2. The cleaning plate 6 and the auxiliary plate 5 are fixedly connected by a connecting plate 16.

[0048] The cleaning plate 6 can drive the auxiliary plate 5 to slide on the filter plate 2.

[0049] As a preferred embodiment of the present invention, an air cylinder 8 is fixedly installed at the bottom end of the auxiliary plate 5. A piston 9 is slidably installed inside the air cylinder 8. One end of the piston 9 is fixedly installed with a sleeve 14. The air cylinder 8 is provided with a first air pipe 10 and a second air pipe 11. The other end of the first air pipe 10 extends into the auxiliary plate 5, and the other end of the second air pipe 11 extends outside the cleaning box 1. One-way valves are provided on both the first air pipe 10 and the second air pipe 11.

[0050] The one-way valve provided on the first air pipe 10 only allows the gas inside the air cylinder 8 to enter the first air pipe 10.

[0051] The one-way valve provided on the second air pipe 11 only allows the gas to enter the inside of the air cylinder 8 through the second air pipe 11.

[0052] When the piston 9 slides from left to right inside the air cylinder 8, at this time, the second air pipe 11 can suck the external gas into the inside of the air cylinder 8. When the piston 9 slides from right to left inside the air cylinder 8, the gas inside the air cylinder 8 can be sent into the inner cavity of the auxiliary plate 5 through the first air pipe 10.

[0053] As a preferred embodiment of the present invention, one end of the water suction pipe far from the circulation pump 3 is fixedly connected with a bent pipe 12. One end of the bent pipe 12 penetrates through the air cylinder 8 and extends below the liquid level. A transmission rod 13 is rotatably installed inside the bent pipe 12. A turbine blade 15 is fixedly installed on the transmission rod 13. One end of the transmission rod 13 extends into the sleeve 14 and is provided with a reciprocating thread groove.

[0054] When the circulation pump 3 is started, the clear water inside the cleaning box 1 can be sucked out through the bent pipe 12. During the flow of the water body, the turbine blade 15 will be impacted, causing it to drive the transmission rod 13 to rotate. At the same time, through the provided reciprocating thread groove, the sleeve 14 can reciprocate inside the air cylinder 8, and at the same time drive the piston 9 to reciprocate. At this time, the gas can be transported to the inner cavity of the auxiliary plate 5 in cooperation with the first air pipe 10 and the second air pipe 11.

[0055] As a preferred embodiment of the present invention, a reciprocating lead screw 17 is rotatably installed inside the cleaning box 1. The auxiliary plate 5 is threadedly installed on the outer wall of the reciprocating lead screw 17. The transmission rod 13 is connected to the reciprocating lead screw 17 through a transmission assembly.

[0056] When the transmission rod 13 is driven to rotate by the turbine blade 15, at this time, the transmission rod 13 can drive the reciprocating lead screw 17 to rotate through the transmission assembly. The transmission assembly can be a common bevel gear set (such as Figure 5 shown). When the reciprocating lead screw 17 rotates, it can drive the auxiliary plate 5 and the cleaning plate 6 to move synchronously.

[0057] As a preferred embodiment of the present invention, an air outlet 30 is provided at one end of the auxiliary plate 5 facing the filter plate 2. A rotating rod 24 is rotatably installed inside the auxiliary plate 5. A blocking block 25 for blocking the air outlet 30 is fixedly installed on the rotating rod 24. A transmission cylinder 28 is slidably installed on the rotating rod 24. One end of the transmission cylinder 28 is fixedly installed with a sealing plug 23. The outer wall of the sealing plug 23 fits against the inner wall of the auxiliary plate 5. A return spring 22 is provided between the sealing plug 23 and the auxiliary plate 5. A spiral groove 27 is formed on the outer wall of the rotating rod 24. A guide block 26 is fixedly installed inside the transmission cylinder 28. One end of the guide block 26 extends into the spiral groove 27.

[0058] By the top pressure of the return spring 22 on the sealing plug 23, the sealing plug 23 can drive the transmission cylinder 28 to always maintain the top pressure on the blocking block 25, and cooperate with the guide block 26 and the spiral groove 27 to always keep the blocking block 25 blocking the air outlet 30.

[0059] When the piston 9 reciprocates inside the air cylinder 8, gas can be transported into the auxiliary plate 5. When the air pressure inside the auxiliary plate 5 gradually increases, the sealing plug 23 can be pushed, and at the same time, the return spring 22 deforms and stores elastic potential energy. And when the sealing plug 23 drives the transmission cylinder 28 to slide in a direction away from the blocking block 25, under the cooperation of the spiral groove 27 and the guide block 26, the rotating rod 24 can drive the blocking block 25 to rotate and release the block on the air outlet 30. At this time, the gas inside the auxiliary plate 5 will be discharged from the air outlet 30 to blow the bottom end of the filter plate 2, which can effectively solve the problem of blockage of the filter plate 2.

[0060] After the gas inside the auxiliary plate 5 is discharged, the air pressure on the sealing plug 23 decreases, and the return spring 22 releases elastic potential energy, which can push the sealing plug 23 and the transmission cylinder 28 back to their original positions, and under the cooperation of the spiral groove 27 and the guide block 26, drive the blocking block 25 to block the air outlet 30 again.

[0061] As a preferred embodiment of the present invention, a conveying auger 18 is rotatably installed inside the cleaning plate 6. The two bottom ends of the cleaning plate 6 are open. A scraping plate 29 is fixedly installed at the bottom end of the cleaning plate 6. Both ends of the scraping plate 29 are inclined. The output shaft of the conveying auger 18 is fixedly installed with a discharge pipe 19. The inner cavity of the discharge pipe 19 is communicated with the inner cavity of the cleaning plate 6. One end of the discharge pipe 19 extends out of the outer wall of the cleaning box 1. A debris receiving box 7 is fixedly installed on the outer wall of the cleaning box 1.

[0062] A rotating gear 20 is fixedly installed on the outer wall of the discharge pipe 19. A toothed plate 21 meshing with the rotating gear 20 is formed inside the cleaning box 1.

[0063] When the reciprocating screw rod 17 rotates to drive the auxiliary plate 5 and the cleaning plate 6 to slide on the filter plate 2, the impurity scraper plate 29 can push the impurities on the surface of the filter plate 2 into the interior of the cleaning plate 6. At the same time, the rotating gear 20 on the discharge pipe 19 will slide on the toothed plate 21, and the discharge pipe 19 will drive the conveying auger 18 to rotate. At this time, the impurities inside the cleaning plate 6 will be conveyed by the conveying auger 18 into the interior of the discharge pipe 19 and finally fall into the interior of the impurity receiving box 7. By cleaning the filter plate 2, the flow rate of the filter plate 2 can be effectively guaranteed, thereby ensuring the efficiency of pre-cleaning the field snails with circulating water.

[0064] Working principle: Under the action of the circulation pump 3, water enters the water outlet pipe 4 and is discharged from the nozzle, and the water is sprayed inside the cleaning barrel 32 to spray the field snails to be cleaned. Then, by starting the drive motor 39, the transmission gear 34 can be driven to rotate, and at the same time, the toothed ring 35 can be driven to rotate, so as to realize the rotation of the stirring frame 36 inside the cleaning barrel 32 and realize the pre-cleaning of the field snails. After cleaning, the transmission gear 34 drives the driving wheel 37 to rotate, and the driven wheel 38 can be driven to rotate through the belt, so as to control the delivery auger 40 and convey the field snails in the cleaning barrel 32 to the interior of the re-washing box 31 through the transfer cylinder 33 for immersion cleaning. By pre-cleaning and immersion cleaning the field snails, the cleaning efficiency of the field snails can be further improved.

[0065] When the circulation pump 3 is started, the clear water inside the cleaning box 1 can be sucked out through the bent pipe 12. During the flow of the water body, the turbine blade 15 will be impacted to drive the transmission rod 13 to rotate. At the same time, through the reciprocating thread groove provided, the sleeve 14 can reciprocate inside the air cylinder 8, and at the same time drive the piston 9 to reciprocate. At this time, the gas can be delivered to the inner cavity of the auxiliary plate 5 in cooperation with the first air pipe 10 and the second air pipe 11. When the air pressure inside the auxiliary plate 5 gradually increases, the sealing plug 23 can be pushed, and at the same time, the return spring 22 deforms and stores elastic potential energy. And when the sealing plug 23 drives the transmission cylinder 28 to slide away from the shielding block 25, under the cooperation of the spiral groove 27 and the guiding block 26, the rotating rod 24 can drive the shielding block 25 to rotate and release the blockage of the air outlet 30. At this time, the gas inside the auxiliary plate 5 will be discharged from the air outlet 30 to blow the bottom end of the filter plate 2, which can effectively solve the problem of blockage of the filter plate 2.

[0066] At the same time, when the cleaning plate 6 drives the discharge pipe 19 to slide, the rotating gear 20 cooperates with the toothed plate 21 to drive the conveying auger 18 to rotate. At this time, the impurities inside the cleaning plate 6 will be conveyed by the conveying auger 18 into the interior of the discharge pipe 19 and finally fall into the interior of the impurity receiving box 7. By cleaning the filter plate 2, the flow rate of the filter plate 2 can be effectively guaranteed, thereby ensuring the efficiency of pre-cleaning the field snails with circulating water.
