Description

Technical Field

[0001] This utility model relates to the field of eel processing technology, and in particular to an eel conveying and sorting device. Background Technology

[0002] As one of the main freshwater farmed fish species in my country, eel is rich in various nutrients and has the effects of nourishing blood and removing dampness. It is a good nutritional supplement for patients with chronic illness, weakness, anemia, and tuberculosis. Eel contains abundant high-quality protein and various essential amino acids. In particular, eel contains a rare protein called West River Locke protein, which has a good effect on strengthening the kidneys and improving sexual function. It is a health food for young couples and middle-aged and elderly people.

[0003] The taste of eels is closely related to their size and weight, so different sizes of eels require different cooking methods. Processing plants often need to sort eels by size to better process them. Chinese patent CN222090667U discloses an eel conveying and sorting device. While this device can perform fine sorting by weight, it is more suitable for small-batch sorting and has relatively low efficiency. In reality, eels are more often sorted in large quantities quickly during procurement, where precise sorting is not required and only a rough sorting based on body shape (mainly thickness) is needed.

[0004] Therefore, another type of sorting device exists, such as the eel size sorting device disclosed in Chinese Patent CN116724943A. This device includes a frame, a fish storage box, and several sorting boxes. The sorting boxes are arranged in a stepped manner on the frame. The fish storage box is connected to the sorting box furthest from the ground. Each sorting box contains a sorting plate with several fish dropping troughs. A through-slot is formed at one end of each adjacent sorting box. A fish discharge trough pipe is provided on the side of the sorting plate away from the fish storage box to receive the eels. One end of the fish discharge trough pipe extends out of the sorting box and connects to the outside. The sorting box structure in this technical solution is relatively large. Furthermore, it relies on the eels' own swimming, which introduces many uncontrollable factors, easily leading to eel accumulation and jamming, slow sorting speed, and incomplete screening. Utility Model Content

[0005] This invention provides an eel conveying and sorting device, which helps to solve the problem that some current eel sorting devices have a large structural volume and are prone to eel accumulation, affecting sorting quality and efficiency.

[0006] This utility model is implemented as follows:

[0007] An eel conveying and sorting device includes a frame with a sorting cylinder that is higher at the front and lower at the back. The sorting cylinder consists of at least two layers of cylinders with inner and outer gaps. A rotary drive mechanism and an axial limiting mechanism are provided on the outer surface of the outer cylinder. Adjacent cylinders are concentrically arranged and connected by several centrally symmetrical connecting blocks to form a synchronously rotating composite cylinder structure. Each cylinder has an open structure at both ends of its axial direction. A feed hopper is gap-connected to the front opening of the radially inner cylinder, and an discharge cylinder and a discharge hopper are independently provided at the opening of each cylinder on the rear side. Several first modules and second modules are arranged in a circular pattern on the radially inner cylinder. The first module includes several tamping flanges that are centrally symmetrical along the cylinder's rotation axis, and the second module includes several screening holes that are centrally symmetrical along the cylinder's rotation axis. The screening holes allow eels smaller than a threshold size to pass through into the inner cavity of the outer cylinder. The tamping flanges and screening holes are parallel spiral segments.

[0008] Based on the above technical solution, the rotary drive mechanism includes a transmission gear ring fixed to the outer surface of the outer cylinder, a transmission gear is provided between the bottom of the transmission gear ring and the frame, and the transmission gear is connected to a reduction motor; the axial limiting mechanism includes a limiting wheel fixed to the outer surface of the outer cylinder, a support wheel is provided between the bottom of the limiting wheel and the frame, and the support wheel and the limiting wheel constitute a limiting structure to prevent the cylinder from falling off axially.

[0009] Based on the above technical solution, several water seepage holes are evenly distributed between adjacent tamping flanges.

[0010] Based on the above technical solution, the corners of the outer contour of the tamping flange are all rounded chamfered structures.

[0011] Based on the above technical solution, the outer contour of the tamping flange is provided with anti-slip texture.

[0012] Based on the above technical solution, the diameter of the screening holes on each inner side of the sorting cylinder decreases progressively from the inside to the outside.

[0013] Based on the above technical solution, the anti-slip texture is a detachable flange structure.

[0014] Based on the above technical solution, the anti-slip texture is a groove structure.

[0015] Based on the above technical solution, an inner liner is attached to the inner side of the screening hole. The inner liner is provided with an adjustment hole that is adapted to its adjacent outer screening hole. By adjusting the installation angle of the inner liner, the communication area between the adjustment hole and its adjacent outer screening hole can be changed, thus forming an adjustable structure for screening specifications.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] 1. Compared with existing stepped sorting box devices, the sorting device of this utility model has a more compact structure and occupies less space. This is of great practical significance for eel processing sites with limited space, and can improve the utilization rate of the site.

[0018] 2. The eel conveying and sorting device of this utility model, through the cooperation of a rotating sorting cylinder and a tamping flange, can effectively push the eels to move within the sorting cylinder, avoiding the accumulation of eels. Compared with existing devices that rely on the eels' own swimming for sorting, the sorting speed is significantly improved, meeting the needs of large-volume eel sorting.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Example 1: Combination Figures 1 to 3This embodiment discloses an eel conveying and sorting device, aiming to solve the problem that some current eel sorting devices are bulky and prone to eel accumulation, affecting sorting quality and efficiency. Through innovative structural design, it achieves efficient and accurate eel sorting, improving the overall efficiency and quality of eel processing.

[0032] like Figure 1 As shown, the eel conveying and sorting device specifically includes a frame 100, which is a frame structure spliced ​​from aluminum profiles. It mainly serves to support and provide a stable installation foundation for other components.

[0033] A sorting cylinder 200, with a higher front and lower rear, is positioned above the frame 100. This inclined design facilitates the transport and sorting of eels within the sorting cylinder 200. The sorting cylinder 200 consists of at least two layers of cylinders with inner and outer gaps. In this embodiment, the sorting cylinder 200 has two cylinders: an outer cylinder 210 and an inner cylinder 220. The outer cylinder 210 is concentrically fitted radially outside the inner cylinder 220. The two are connected and fixed by several centrally symmetrically distributed connecting blocks 230, forming a synchronously rotating composite cylinder structure. This structure allows each cylinder to rotate synchronously, ensuring the coordination and stability of the sorting process. The rear end of the inner cylinder 220 extends to the outside of the outer cylinder 210, causing the discharge end of the inner cylinder 220 to be axially offset from the discharge end of the outer cylinder 210. This facilitates the convenient collection and transportation of sorted eels using a receiving device.

[0034] A rotary drive mechanism and an axial limiting mechanism are provided on the outer surface of the outer cylinder. The rotary drive mechanism includes a transmission gear ring 300 fixed to the outer surface of the outer cylinder. Figure 2 The transmission gear ring 300 (simplified drawing) has a transmission gear 310 between its bottom and the frame 100. The transmission gear 310 is connected to a reduction motor 320, which provides power. Through the meshing of the transmission gear 310 and the transmission gear ring 300, the sorting cylinder 200 is rotated. This transmission method is simple, reliable, and can accurately control the rotational speed of the sorting cylinder 200. The axial limiting mechanism includes a limiting wheel 400 fixed to the outer surface of the outer cylinder. A support wheel 410 is provided between the bottom of the limiting wheel 400 and the frame 100. The support wheel 410 and the limiting wheel 400 form an axial anti-falling limiting structure for the cylinder. During the rotation of the sorting cylinder 200, the support wheel 410 and the limiting wheel 400 cooperate to prevent the sorting cylinder 200 from shifting or falling off axially, ensuring the stability of the sorting process. The rotary drive mechanism and axial limiting mechanism are existing technologies. Their specific structures and working principles can be found in the relevant content of patent CN202121442019.3, and will not be repeated here. Those skilled in the art can select and implement them from the existing technologies according to the actual operation.

[0035] Each cylinder has open ends along its axial direction. A feed hopper 500 is gapped at the front opening of the radially inner cylinder, through which the eels enter the sorting cylinder 200. Each cylinder at its rear opening has an independent discharge cylinder and discharge hopper, specifically, as follows... Figure 1 As shown, in this embodiment, the outer cylinder 210 has a first discharge cylinder 600 spaced apart at its discharge end. A first discharge hopper 610 is located at the bottom of the first discharge cylinder 600, and a first material box 620 is located below the first discharge hopper 610. Eels in the inner cavity of the outer cylinder 210 (i.e., the space between the inner wall of the outer cylinder 210 and the outer wall of the inner cylinder) are discharged and enter the first material box 620. In this embodiment, the inner cylinder 220 has a second discharge cylinder 700 spaced apart at its discharge end. A second discharge hopper 710 is located at the bottom of the second discharge cylinder 700, and a second material box 720 is located below the second discharge hopper 710. Eels in the inner cavity of the inner cylinder 220 (the larger, unscreened portions) are discharged and enter the second material box 720.

[0036] Furthermore, in combination Figure 2 and Figure 3 As shown, the inner wall of the inner cylinder 220 is provided with three sets of circulating first modules a and second modules b. The first module a includes several symmetrically arranged material-stirring flanges 221 along the central axis of rotation of the cylinder. During rotation, the material-stirring flanges 221 can stir and push the eels, preventing them from piling up and promoting their movement within the sorting cylinder 200. The second module b includes several symmetrically arranged screening holes 223 along the central axis of rotation of the cylinder. The screening holes 223 allow eels smaller than the threshold size to pass through into the outer inner cavity of the cylinder, thereby achieving size sorting of the eels.

[0037] The tamping flange 221 and the sieve hole 223 are parallel spiral segments, which can better guide the movement direction of the eel and improve sorting efficiency.

[0038] Furthermore, several drainage holes 222 are evenly distributed between adjacent tamping flanges 221. During the eel sorting process, water may be carried out from the eels. The drainage holes 222 can drain the water in time, preventing water from accumulating in the sorting cylinder 200 and affecting the sorting effect. In actual operation, the rotation of the tamping flanges 221 can effectively drive the movement of the eels on the inner side. During this process, the drainage holes 222 can drain excess water in time, making the water content of the eels relatively low. In this state, the mucus carried by the eels can fully contact the inner wall of the inner cylinder 220 and remain on the inner wall, forming a lubricating mucous film layer on the inner wall of the inner cylinder 220. This further improves the flexibility of the eels' movement inside. Under the influence of the tamping flanges 221, they move evenly and efficiently and contact the inner wall structure of the inner cylinder 220, improving the eel screening effect and efficiency.

[0039] The outer contour corners of the mixing flange 221 are all rounded and chamfered. This design can avoid damage to the eel during the stirring and pushing process, thus ensuring the integrity of the eel.

[0040] To ensure the effective tamping of the material by the tamping flange 221, anti-slip textures 224 are provided on the outer contour of the tamping flange 221. The anti-slip textures 224 increase the friction between the tamping flange 221 and the eel, better propelling the eel and preventing it from slipping inside the sorting cylinder 200. Figure 4 and Figure 5 The anti-slip texture 224 can be a detachable flange structure. Figure 5 The anti-slip texture 224 is a sheet-like structure, which is connected and locked to the tamping flange 221 by countersunk bolts. This structure is easy to replace according to different sorting needs, improving the versatility of the device. In other embodiments, it can also be a groove structure, which can also increase the friction.

[0041] It should be noted that the diameter of the screening holes 223 on each inner side of the sorting cylinder 200 decreases progressively from the inside to the outside. This allows for multi-level sorting based on the size of the eels, enabling eels of different sizes to pass through the screening holes 223 of the corresponding diameter, thus achieving precise sorting.

[0042] In the specific implementation process, the eels to be sorted are continuously conveyed from the feed hopper 500 to the input end of the inner cylinder 220 by an external conveyor. As the sorting cylinder 200 rotates, the eels rotate inside. Eels with a size smaller than the inner diameter of the screening hole 223 pass through the screening hole 223 from the inside to the outside during the tumbling and moving process, and are transferred from the inner cavity of the inner cylinder 220 to the inner cavity of the outer cylinder 210 (the gap between the outer cylinder 210 and the inner cylinder 220), forming a screening effect of internal and external size classification. Then, they are independently separated and output to the first material box 620 and the second material box 720.

[0043] Example 2: Based on Example 1, combined with Figure 6 As shown, in this embodiment, an inner liner 240 is fitted to the inner side of the screening hole 223. The inner liner 240 is provided with an adjustment hole 241 adapted to its adjacent outer screening hole 223. By adjusting the installation angle of the inner liner 240, the communication area between the adjustment hole 241 and its adjacent outer screening hole 223 can be changed, thus forming an adjustable structure for screening specifications. This adjustable structure allows the device to adapt to the sorting needs of eels of different sizes, improving the flexibility and applicability of the device.

[0044] This utility model's eel conveying and sorting device effectively solves some problems existing in current eel sorting devices through innovative structural design and novel technical means. The device boasts advantages such as improved sorting efficiency, guaranteed sorting quality, compact structure, high versatility, and flexibility, meeting the needs of different stages of eel farming, processing, and sales. Furthermore, this device has broad market prospects and is expected to play a significant role in the field of eel processing technology, promoting the development of the eel industry.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
