Abstract
Description
Technical Field
[0001] This utility model belongs to the field of snail processing technology, specifically relating to a high-efficiency snail shelling and cleaning machine. Background Technology
[0002] Snails are common mollusks that mainly inhabit freshwater rivers, lakes, and paddy fields. They are highly nutritious, containing abundant protein, vitamins, and trace elements. Therefore, snail meat is widely consumed and is considered a specialty dish in some regions. To improve the efficiency of snail meat extraction, automatic snail shelling and cleaning machines are generally used for processing. These machines typically employ mechanized operations, automating the shelling process, reducing manual labor, and increasing production efficiency.
[0003] An existing patent, CN221241528U, describes an automatic snail shelling and cleaning machine. This patent includes a shell, a crushing device, and a cleaning device. The crushing device is located inside the shell, with both ends penetrating the inner wall of the shell. These ends can move within the shell, causing the snails to fall onto the thicker ends of multiple fixed rods. These fixed rods are conical, and the gap between them gradually increases. Under their own weight, the snails roll along the rods from the thicker end to the thinner end. During this process, smaller snails fall first between two corresponding fixed rings. A drive device rotates two rotating columns, which in turn rotate the fixed rings, squeezing the snails. This structure allows for shelling snails of different sizes, offering some convenience. However, in practical use, it has the following shortcomings: Firstly, it cannot efficiently shell snails of different sizes, reducing shelling efficiency. Secondly, it cannot perform cleaning operations based on the shelling process, further reducing processing efficiency.
[0004] Therefore, there is a need for a high-efficiency snail shelling and cleaning machine to solve the problems of existing technologies that cannot efficiently shell snails of different sizes and are inconvenient for coordinated cleaning. Utility Model Content

[0024] The present invention will be further described below with reference to the embodiments.
[0025] Please see Figure 1-4This utility model provides a high-efficiency shelling and cleaning machine for snails, including a cleaning tank 1, a feed inlet 2, and a discharge outlet 3. The feed inlet 2 is fixedly connected to the top front side of the cleaning tank 1, and the discharge outlet 3 is fixedly installed at the bottom right side of the cleaning tank 1. A cleaning mechanism 4 is provided at the bottom of the cleaning tank 1, and a shelling mechanism 5 is provided on the cleaning tank 1. A material distribution mechanism 6 is provided below the feed inlet 2 and inside the cleaning tank 1. The material distribution mechanism 6 is located above the shelling mechanism 5, and a controller 101 is fixedly connected to the right surface of the cleaning tank 1.
[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that the cleaning mechanism 4 includes a water tank 401, which is fixedly installed at the bottom of the cleaning tank 1. A pump 402 is fixedly installed at the front of the water tank 401. A connecting pipe 403 is connected to the pump 402. A spray pipe 404 is fixedly connected to the other end of the connecting pipe 403. The spray pipe 404 is set inside the cleaning tank 1. A nozzle 405 is fixedly installed on the surface of the spray pipe 404. Several nozzles 405 are evenly distributed on the surface of the spray pipe 404.
[0027] During use, the pump 402 operates to transport water from the water tank 401 to the spray pipe 404 during the shelling process. The spray nozzle 405 then cleans the snails processed in the cleaning tank 1, thereby improving the processing efficiency. The processed snails are then discharged through the discharge port 3.
[0028] As can be seen from the above working process, the cleaning mechanism 4 can perform a thorough cleaning operation on the snails processed in the cleaning box 1 according to the processing process, thereby improving the processing efficiency of snails.
[0029] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the shelling mechanism 5 includes a motor 501, which is fixedly installed on the front surface of the cleaning tank 1. A crushing roller 502 is fixedly connected to the output shaft end of the motor 501. The crushing roller 502 is arranged in a conical frustum shape and expands forward. A partition 5021 is fixedly connected to the surface of the crushing roller 502. Four partitions 5021 are arranged on the surface of the crushing roller 502 and are evenly distributed to divide the crushing roller 502 into three sections. The crushing roller 502 is rotatably arranged in the cleaning tank 1 through bearings. A drive gear 503 is fixedly connected to the outer side of the front end of the crushing roller 502. A driven gear 504 is meshed on the left side of the drive gear 503. A positioning roller 505 is fixedly connected to the rear of the driven gear 504. The positioning roller 505 is rotatably arranged in the cleaning tank 1 through bearings.
[0030] In use, the operation of motor 501 causes crushing roller 502 to rotate, and the rotation of drive gear 503 drives driven gear 504 to rotate, thereby causing positioning roller 505 to rotate in conjunction with the rotation of crushing roller 502 to complete the crushing and processing operation of snails.
[0031] Further as Figure 2 and Figure 3 As shown, it is worth noting that the material distribution mechanism 6 includes a feeding plate 601, which is fixedly connected to the inner wall of the cleaning tank 1 below the feed inlet 2. A fixing plate 602 is fixedly connected to the upper right side of the feeding plate 601 at the top of the cleaning tank 1. A gap exists between the feeding plate 601 and the fixing plate 602. A second screen plate 606 is fixedly connected to the front left side of the fixing plate 602. A first screen plate 605 is fixedly connected to the rear of the second screen plate 606. A second baffle 604 is fixedly connected to the rear bottom of the second screen plate 606 and connected to the feeding plate 601. A second baffle 604 is fixedly connected to the rear bottom of the first screen plate 605. A baffle 603 is connected to the feed plate 601. A second guide plate 608 is fixedly connected to the front of the second baffle 604. A first guide plate 607 is fixedly connected to the front of the first baffle 603. The front of the second baffle 604 is separated from the front section of the crushing roller 502. The first baffle 603 and the second baffle 604 are set in the middle section of the crushing roller 502. The aperture of the second screen plate 606 is smaller than the aperture of the first screen plate 605. The first screen plate 605 and the second screen plate 606 are arranged at an angle, with the front higher than the rear. The first guide plate 607 and the second guide plate 608 are set at an angle to guide the material forward.
[0032] In use, the smallest snails are screened out by the second screen plate 606 and fall onto the upper part of the second guide plate 608. They are then guided by the second guide plate 608 through the feed plate 601 to the front section of the crushing roller 502. Since the gap between the front section of the crushing roller 502 and the positioning roller 505 is minimal, the smallest snails are crushed and deshelled. The first screen plate 605 can screen medium-sized snails, which are then guided by the first guide plate 607 to the upper middle section of the crushing roller 502 for crushing and deshelling. The largest snails are guided by the rear part of the first screen plate 605 onto the feed plate 601 to the upper rear section of the crushing roller 502 for crushing and deshelling.
[0033] This solution has the following working process: When this device is in use, snails are poured into the cleaning tank 1 through the feed inlet 2 for processing. At this time, the snails fall onto the upper part of the second screen plate 606. The smallest snails are screened out by the second screen plate 606 and fall onto the upper part of the second guide plate 608. Through the second guide plate 608, the snails are guided by the feed plate 601 to the front section of the crushing roller 502. The operation of the motor 501 causes the crushing roller 502 to rotate, and the rotation of the drive gear 503 drives the driven gear 504 to rotate, thereby causing the positioning roller 505 to rotate in conjunction with the rotation of the crushing roller 502 to complete the crushing operation of the snails. Due to the gap between the front section of the crushing roller 502 and the positioning roller 505, The smallest snails are crushed and deshelled, while medium-sized snails are screened by the first screen plate 605 and guided by the first guide plate 607 to the middle section of the crushing roller 502 for crushing and deshelling. The largest snails are guided by the rear of the first screen plate 605 onto the feed plate 601 to the rear section of the crushing roller 502 for crushing and deshelling. During the deshelling process, the pump 402 is used to transport water from the water tank 401 to the spray pipe 404, so that the snails processed in the cleaning tank 1 are cleaned by the spray nozzle 405, thereby improving the processing efficiency. The processed snails are discharged through the discharge port 3.
[0034] In summary: the cleaning mechanism 4 can thoroughly clean the snails processed in the cleaning tank 1 according to the processing procedure, thereby improving the processing efficiency of snails; the shelling mechanism 5, in conjunction with the material distribution mechanism 6, facilitates the screening of snails according to their size, so as to complete the corresponding shelling and crushing work according to snails of different sizes, thereby improving the processing quality and efficiency of snails.
