[0004] However, due to the wide variety of aquatic products, it is impossible to accurately identify the shape of aquatic products through shooting in a single direction, making it difficult to quickly identify the types of aquatic products, which is not conducive to the rapid sampling and classification of aquatic products.

A distribution component can push aquatic products on the main conveyor line to the branch conveyor line. Combined with the shooting component, the sampled aquatic products can be accurately identified, achieving the effect of rapid identification of the type of aquatic products.

[0006] In order to solve the problems of the existing technology, the present invention provides a device for quickly identifying the categories of aquatic products by sampling, including a main conveyor line and a branch conveyor line vertically connected to the main conveyor line. The device for quickly identifying the categories of aquatic products by sampling also includes a cylinder fixed in the main conveyor line, and the lifting end of the cylinder is fixedly installed with a carrier frame inserted in the transmission roller of the main conveyor line, and a gravity sensor for weighing and identifying aquatic products is installed on the carrier frame; a support frame is fixedly installed on the branch conveyor line, and a distribution component for pushing the aquatic products on the main conveyor line to the branch conveyor line is provided on the support frame, and a shooting component for multi-directional shooting of the aquatic products on the branch conveyor line is also provided on the support frame; a limit frame for limiting the weighing detection of aquatic products is rotatably installed on the support frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model is provided with a carrier frame that can push the aquatic products transmitted on the independent conveyor line for weighing. According to the weighed weight, the aquatic products within a certain weight range can be quickly distinguished, and after weighing, the distribution component is driven to push the aquatic products on the main conveyor line to the branch conveyor line. The aquatic products on the branch conveyor line are further identified by the shooting component. Through the two conveyor lines, different categories of aquatic products can be sorted by weight once and then photographed for accurate identification, which improves the efficiency of random inspection of aquatic products and the accuracy of type identification.

[0015] 2. The utility model is provided with a directional drive mechanism that can shoot and identify aquatic products in all directions.

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figure 1-Figure 7As shown, the device for rapid classification of aquatic product sampling includes a main conveyor line 1 and a branch conveyor line 2 vertically connected to the main conveyor line 1. The device for rapid classification of aquatic product sampling also includes a cylinder 11 fixed in the main conveyor line 1. The lifting end of the cylinder 11 is fixedly installed with a carrier 12 inserted into the transmission roller of the main conveyor line 1. The carrier 12 is equipped with a gravity sensor 13 for weighing and identifying aquatic products; a support frame 21 is fixedly installed on the branch conveyor line 2, and a distribution component 22 for pushing aquatic products on the main conveyor line 1 to the branch conveyor line 2 is provided on the support frame 21. The support frame 21 is also provided with a shooting component 23 for multi-directional shooting of aquatic products on the branch conveyor line 2; the main conveyor line 1 is provided with a notch at the connection with the branch conveyor line 2 so as to push the aquatic products on the main conveyor line 1 to the branch conveyor line 2; the position of the supporting frame 12 corresponds to the position of the branch conveyor line 2; a limit frame 4 for limiting the weighing detection of aquatic products is rotatably installed on the support frame 21, and the limit frame 4 rotates correspondingly to the supporting frame 12, and the distance between the limit frame 4 and the supporting frame 12 is slightly larger than the height of the fish, which limits the fish to remain on the supporting frame 12 when weighing.

[0033] Different types of aquatic products are placed on the main conveyor line 1 for conveyance. When the aquatic products are conveyed to the position above the carrier 12, the cylinder 11 is operated to push the carrier 12 upward. The carrier 12 pushes the aquatic products on the main conveyor line 1 upward, so that the aquatic products move up and are mounted on the carrier 12. The gravity sensor 13 installed on the carrier 12 detects the gravity of the aquatic products and preliminarily identifies the type of the aquatic products based on the detected weight of the aquatic products. After the gravity detection, the cylinder 11 controls the carrier 12 to move downward, so that the aquatic products on the carrier 12 return to the main conveyor line 1. For aquatic products within the gravity detection range, the distribution component 22 is operated to push the aquatic products on the main conveyor line 1 to the branch conveyor line 2. In the process of pushing the aquatic products to move, the distribution component 22 controls the shooting component 23 on the branch conveyor line 2 to rotate and switch the shooting angle. The shooting component 23 can shoot and identify the aquatic products in all directions, thereby improving the accuracy of identifying the types of aquatic products.

[0034] See also Figure 4 、 Figure 5 and Figure 10 As shown, the distribution assembly 22 includes a mobile frame 221 slidably mounted on the support frame 21, a distribution plate 222 is fixedly mounted on the mobile frame 221, a driven rack 223 is fixedly mounted on the mobile frame 221, and a driving gear 224 engaged with the driven rack 223 is rotatably mounted on the support frame 21; the driving gear 224 is interconnected with the output end of the motor fixed on the mobile frame 221.

[0035] The driving gear 224 is controlled to rotate. The driving gear 224 controls the movable frame 221 installed on the support frame 21 to move in a directional manner through meshing transmission with the driven rack 223. The movable frame 221 drives the distribution plate 222 to move synchronously. The distribution plate 222 pushes the aquatic products on the main conveyor line 1 to the branch conveyor line 2.

[0036] See also Figure 4-Figure 7 As shown, the shooting assembly 23 includes a bogie 231 rotatably mounted on the support frame 21 , two groups of industrial cameras 232 are symmetrically fixed on the bogie 231 , and a directional driving mechanism 233 for controlling the bogie 231 to rotate at a certain angle is provided on the support frame 21 .

[0037] When the aquatic products are initially pushed onto the branch conveyor line 2, the industrial cameras 232 on both sides of the bogie 231 are distributed on both sides of the edge of the branch conveyor line 2. The speed at which the branch conveyor line 2 conveys the aquatic products is greater than the speed at which the distribution plate 222 pushes them. After the aquatic products move onto the branch conveyor line 2, they gradually move and separate from the distribution plate 222. The mobile frame 221 and the distribution plate 222 continue to move toward the direction close to the branch conveyor line 2. Under the driving action of the mobile frame 221, the directional rotation of the bogie 231 can be controlled by the directional drive mechanism 233. The bogie 231 rotates to switch the shooting angle of the industrial camera 232, so that the two groups of industrial cameras 232 are both at the central axis position of the branch conveyor line 2, so that the industrial camera 232 can shoot and identify the aquatic products on the branch conveyor line 2 in all directions.

[0038] See also Figure 4-10 As shown, the directional drive mechanism 233 includes a directional disk 2331 fixed on the bogie 231, a slot 2332 is provided on the directional disk 2331, and a slide groove 2333 is also provided on the directional disk 2331. A driven gear 2334 is rotatably installed on the support frame 21, and a turntable 2335 is coaxially fixedly connected to the driven gear 2334. The turntable 2335 is engaged with the slot 2332 on the directional disk 2331, and a push rod 2336 is fixed on the turntable 2335. The push rod 2336 is rotatably assembled with the slide groove 2333; an active rack 2337 is fixedly installed on the movable frame 221, and the active rack 2337 is engaged with the driven gear 2334.

[0039] The movement of the movable frame 221 drives the active rack 2337 to move synchronously. When the active rack 2337 moves and engages with the driven gear 2334, the driven gear 2334 is controlled to rotate through the meshing transmission structure. The driven gear 2334 drives the turntable 2335 to rotate synchronously. The turntable 2335 drives the push rod 2336 to rotate in a circle, so that the push rod 2336 rotates into the slide groove 2333 opened on the directional disk 2331. The push rod 2336 pushes the directional disk 2331 to rotate in a directional manner through the sliding structure with the slide groove 2333. The directional disk 2331 drives the bogie 231 to rotate synchronously in a directional manner, switching the shooting angle of the industrial camera 232 at a fixed angle.

[0040] See also Figure 4 、 Figure 5 and Figure 10 As shown, a limiting round rod 2211 is fixedly installed on the movable frame 221 , and a limiting slot 2212 is provided on the rotating disk 2335 , and the limiting round rod 2211 moves to engage with the limiting slot 2212 .

[0041] When the active rack 2337 follows the movement of the mobile frame 221 and does not contact the driven gear 2334, the limiting round rod 2211 on the mobile frame 221 is engaged in the limiting groove 2212 opened on the turntable 2335. The rotation angle of the turntable 2335 is limited by the engaging structure, thereby limiting the angle of the directional disk 2331 and the bogie 231, and keeping the industrial camera 232 stable in the shooting and detection position. When the active rack 2337 follows the movement of the mobile frame 221 and engages with the driven gear 2334, the limiting round rod 2211 on the mobile frame 221 moves and separates from the limiting groove 2212. At this time, the meshing transmission structure of the active rack 2337 and the driven gear 2334 can control the rotation of the turntable 2335, and the bogie 231 is driven to rotate.

[0042] See also Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, a guide assembly 3 for adjusting the conveying position of aquatic products is installed on the main conveying line 1.

[0043] When the aquatic products are moved and transported on the main conveyor line 1, with the assistance of the guide component 3, the position of the aquatic products on the main conveyor line 1 can be adjusted so that the aquatic products are transported as centered as possible, thereby avoiding the aquatic products moving to the position above the carrier 12 and deviating to one side to affect the weighing detection.

[0044] See also Figure 1 、 Figure 2 、 Figure 11 and Figure 12As shown, the guide assembly 3 includes a guide frame 31 slidably mounted on the main conveyor line 1, a vibration guide seat 32 is fixedly mounted on the guide frame 31, a cam 33 is rotatably mounted on the main conveyor line 1, a vertical rod 34 is fixedly connected to the cam 33 eccentrically, and the vertical rod 34 is slidably connected to the guide frame 31; the cam 33 is interconnected with the motor output end on the main conveyor line 1.

[0045] The control cam 33 rotates, and the vertical rod 34 on the cam 33 is engaged in the guide frame 31 to slide and move. The control guide frame 31 is installed on the main conveyor line 1 to slide back and forth. The guide frame 31 drives the two groups of vibrating guide seats 32 to move back and forth. The moving vibrating guide seats 32 adjust the conveying position of the aquatic products on the main conveyor line 1, and keep the aquatic products in a centered position for transmission on the main conveyor line 1.

[0046] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
