Description

Technical Field

[0001] This utility model relates to the field of conger eel freshness detection technology, and more specifically, to a conger eel processing and sorting device. Background Technology

[0002] The conger eel, also known as the star conger eel, starry glutinous eel, or sand eel, is a marine fish belonging to the genus Congere in the family Congeridae.

[0003] Currently, hyperspectral imaging is used to determine the freshness of conger eels with different death times (the essence of hyperspectral imaging is to establish a quantitative relationship with freshness indicators by capturing the molecular vibrational spectral characteristics and spatial distribution information of the surface and subcutaneous tissue of conger eels). After detection, unqualified conger eels (i.e., those with a long death time and spoilage) are manually removed. However, when detecting the freshness of conger eels, the postures of the eels are varied (curled up, stacked, etc.), and the position cannot be limited, which can easily affect the subsequent hyperspectral imaging detection results. In summary, the hyperspectral freshness detection and sorting process of conger eels needs further optimization. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a processing and sorting device for conger eels.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A processing and sorting device for conger eels includes a chain conveyor belt and a hyperspectral imager. The chain conveyor belt comprises several chain plates and a placement plate. The placement plate is fixed on the chain plate, and the placement plate has multiple placement slots of different sizes; The mounting frame is fixed on the ground on one side of the chain conveyor belt, and the mounting frame is equipped with a hyperspectral imager and a detection component located above the placement plate; The fixed frame is fixed to one side baffle of the chain conveyor belt, and a dual-shaft device is installed on the fixed frame; The mounting plate is connected to a dual-axis device, and fixed rods corresponding to the placement slots are movably mounted on the mounting plate. Spikes are welded onto each fixed rod; The liftable unloading assembly is mounted on the mounting plate and allows spikes to pass through; The collection box is set on the baffle on the other side of the chain conveyor belt.

[0006] Furthermore, the unloading assembly includes a telescopic cylinder and a pusher plate. The telescopic cylinders are symmetrically fixed on the mounting plate, and the telescopic cylinders are connected to a pusher plate that allows sharp spikes to pass through.

[0007] Furthermore, the frame of the chain conveyor belt is equipped with ultraviolet germicidal lamps located below the chain plates on its return path.

[0008] Furthermore, the dual-axis device includes a lead screw assembly and an electric cylinder. The lead screw assembly is mounted on a fixed frame, and an electric cylinder is mounted on the lead screw assembly. The electric cylinder is connected to a mounting plate.

[0010] Furthermore, a support plate is provided on the other side baffle of the chain conveyor belt, and a collection box is placed on the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Compared with existing technologies, this application can achieve positional limitation during the automatic transfer of conger eels, thus making it less likely for phenomena such as curling and stacking to occur. As a result, the placement posture of the conger eels is basically consistent, and the subsequent hyperspectral imaging detection results are more accurate.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figures 1 to 3 As shown, a conger eel processing and sorting device includes a chain conveyor belt 1 and a hyperspectral imager 5. The chain conveyor belt 1 includes several chain plates 101, and also includes a placement plate 2, a placement trough 3, a mounting frame 4, a detection piece 6, a fixing frame 7, a dual-axis device 8, a mounting plate 9, a fixing rod 10, spikes 11, a discharge assembly 12, and a collection box 13. The placement plate 2 is fixed on the chain plate 101, and the placement plate 2 has multiple placement slots 3 of different sizes. Mounting frame 4 is fixed on the ground on one side of chain conveyor belt 1, and a hyperspectral imager 5 and a detection piece 6 are installed on mounting frame 4 above the placement plate 2. The fixed frame 7 is fixed on one side baffle of the chain conveyor belt 1, and the fixed frame 7 is equipped with a dual-shaft device 8; Mounting plate 9 is connected to dual-axis equipment 8, and mounting plate 9 is movably mounted with fixing rods 10 corresponding one-to-one with placement slot 3; Spike 11 is welded to each fixing rod 10; The liftable unloading assembly 12 is mounted on the mounting plate 9, and the unloading assembly 12 allows the spikes 11 to pass through; The collection box 13 is set on the other side baffle of the chain conveyor belt 1 (specifically, a support plate 15 is set on the other side baffle of the chain conveyor belt 1, and the collection box 13 is placed on the support plate 15).

[0014] Specific implementation of this utility model solution, such as Figure 3 As shown, the unloading assembly 12 includes a telescopic cylinder 121 and a pusher plate 122. The telescopic cylinder 121 is symmetrically fixed on the mounting plate 9, and the telescopic cylinder 121 is connected to a pusher plate 122 that allows the spike 11 to pass through.

[0015] Specific implementation of this utility model solution, such as Figure 1 and Figure 3 As shown, the dual-axis device 8 includes a lead screw assembly and an electric cylinder (the lead screw assembly and electric cylinder are not labeled in the figure. The lead screw assembly consists of a servo motor, a lead screw, a slide rail, and a slider. It is existing technology and no improvements are made. Its principle is to convert the rotational motion of the motor into the linear motion of the slider along the slide rail). The lead screw assembly is mounted on the fixed frame 7, and an electric cylinder is mounted on the lead screw assembly. The electric cylinder is connected to the mounting plate 9.

[0016] To ensure that each placement plate 2 can accurately move to the location below the hyperspectral imager 5 for freshness detection of the conger eels in its respective placement tank 3, further optimizations to the above embodiment are possible, such as... Figure 1 and Figure 2 As shown, the inspection piece 6 uses a CCD camera, and there is an empty chain plate 101 between two adjacent placement plates 2. The purpose of the empty chain plate 101 between two adjacent placement plates 2 is to provide the staff with sufficient time for placement and retrieval.

[0017] To automatically sterilize the placement tank 3, further optimizations to the above-described embodiments are made, such as... Figure 4 As shown, an ultraviolet germicidal lamp 14 is installed on the frame of the chain conveyor belt 1 below the chain plate 101 on its return path.

[0018] It should be noted that the drive components of the chain conveyor belt 1, the hyperspectral imager 5, the detection component 6, the dual-axis device 8, and the telescopic cylinder 121 are all electrically connected to the PLC control panel. The electrical connection of the PLC control panel is not shown in the figure, but it can be installed on the frame of the chain conveyor belt 1.

[0019] The working process of this utility model is as follows: First, the conger eels are fully unfolded and placed into one of the placement slots 3 of the placement plate 2 by manual operation from the initial end of the chain conveyor belt 1. The purpose of setting multiple placement slots 3 on a placement plate 2 is to accommodate conger eels of different sizes (larger conger eels are placed in larger placement slots 3, smaller conger eels are placed in smaller placement slots 3, and conger eels of medium size are placed in the middle placement slots 3, with only one placement slot 3 containing conger eels and the other two placement slots 3 remaining empty. After placement, the placement slots 3 are basically in close contact with the conger eels). After being placed, the conger eels move intermittently along the chain conveyor belt 1 and move under the hyperspectral imager 5. When the CCD camera captures and identifies one of the placement plates 2 moving under it, the CCD camera sends a signal back to the PLC control panel (the image of the placement plate 2 is transmitted to the PLC control panel in advance). Then the PLC control panel controls the chain conveyor belt 1 to stop, and the freshness of the conger eels on the current placement plate 2 can be detected by the hyperspectral imager 5. If the freshness of the conger eel is found to be substandard, the hyperspectral imager 5 sends a feedback signal to the PLC control panel. The PLC control panel then controls the chain conveyor belt 1 to resume operation. After the substandard conger eel moves once more with the placement plate 2, it will be positioned directly below the spikes 11. The PLC control panel then controls the electric cylinder in the dual-axis device 8 to operate, causing several spikes 11 to move down synchronously and enter the three placement slots 3. The spikes 11 will then pass through the conger eel (the descent distance is preset in the PLC control panel). After penetration, the PLC control panel controls the electric cylinder to retract, causing the conger eel to detach from the placement slot 3. Then, under the action of the lead screw assembly, the conger eel moves to the top of the collection box 13. After reaching its position, the PLC control panel controls the unloading assembly 12 to operate, causing the substandard conger eel to detach from the spikes 11 and be collected (this part of the conger eel has already spoiled and can be directly processed later). If the conger eel is found to be qualified, the chain conveyor belt 1 will resume operation. Then the subsequent placement plate 2 can move to the hyperspectral imager 5 for testing. At this time, the qualified conger eel will not leave the placement trough 3. It will move with the placement plate 2 to the end of the chain conveyor belt 1 and can be manually transferred. After the transfer, other subsequent processes can be carried out. In summary, this application can achieve positional limitation during the automatic transfer of conger eels, thus preventing phenomena such as curling and stacking. As a result, the placement posture of the conger eels remains basically consistent, leading to more accurate subsequent hyperspectral imaging detection results. Furthermore, when unqualified conger eels are detected, they can be automatically sorted and collected in a directional manner, thereby completing the automatic rejection process for unqualified conger eels and improving the degree of automation.
