Description

Technical Field

[0001] The utility model belongs to the technical field of fish processing, and particularly relates to an automatic weighing device for live fish. Background Art

[0002] In the field of aquatic product processing, the weight of aquatic products is one of the important parameters for classifying aquatic products, and most aquatic products are classified according to their weight. During the processing of aquatic products, the weight of aquatic products is often obtained by automatically weighing them during transportation. In the field of fish processing, a layout method of combining a weighing device with a transportation device is usually adopted to obtain the weight of fish during transportation. The existing weighing device is arranged between two conveyor belts, and fish fall into the weighing device from the first conveyor belt for weighing. However, since the fish fall from a high place into the weighing device, a large impact will be generated at the moment when the fish come into contact with the weighing device. Moreover, due to the certain elasticity of the fish itself, the fish will bounce to a certain extent after falling into the weighing device, which is likely to damage the fish epidermis, and the accurate weight of the fish cannot be obtained when the fish are bouncing, resulting in low weighing efficiency.

[0003] For this reason, an automatic weighing device for fish with the publication number of "CN218628577U" includes a feeding mechanism, a weighing mechanism, and a discharging mechanism arranged in sequence. The weighing mechanism includes a frame and a weighing and transporting device. The weighing and transporting device includes a plurality of belt transporting mechanisms arranged side by side, and also includes a liftable weighing component, and the weighing component is arranged below the belt transporting mechanism; the weighing component includes a driving unit, and the driving unit is fixedly connected to the frame; it also includes a movable plate, and the movable plate is connected to the output end of the driving unit. The weighing component also includes a pressure sensor, and the pressure sensor is fixedly connected to the movable plate; it also includes a supporting component arranged above the pressure sensor. The supporting component jacks up the fish from the belt transporting mechanism under the drive of the driving unit, and at the same time, the pressure sensor weighs the fish. When weighing, it will not cause the fish to bounce, can protect the fish epidermis, and because it will not cause the fish to bounce, the weight of the fish can be quickly obtained, improving the efficiency.

[0004] However, for the automatic weighing device for fish, although the feeding mechanism transports the fish from the previous process to the weighing mechanism, after the sensing component of the weighing mechanism senses that the fish is in place, the weighing mechanism stops transporting, and the weighing component weighs the fish at the same time. After weighing, the weighing mechanism sends the fish to the unloading mechanism, and the unloading mechanism sends the fish to the next process. However, there are still the following obvious defects during use: although the conveying lines in the feeding mechanism and the unloading mechanism of the weighing device can filter out the moisture carried by the live fish during transportation, since there is no component on the feeding mechanism and the unloading mechanism to collect the water generated during the transportation of the live fish, it is easy for water to flow to the conveying platform in the feeding mechanism and the unloading mechanism to accumulate water, so that the conveying line will be corroded, rusted and damaged after a long time of accumulation of water.

And conveying baffle plate members 4 are provided on the front and rear sides of the end of the blanking conveyor line 1 to prevent the phenomenon that live fish jump out of the conveyor line during conveying. One end inside the weighing conveyor rack 2 is provided with a weighing conveyor roller 5 that is connected and conveyed with the conveyor belt in the blanking conveyor line 1. The weighing conveyor rollers 5 are uniformly arranged on the rotating shaft rod 11. During the conveying of live fish by the receiving rod, weighing operations are carried out. A weighing platform 6 for automatically weighing the conveyed live fish is provided between the inner sides of the weighing conveyor rollers 5, achieving the effect of weighing the live fish during conveying and reducing the stop of the conveyor line for live fish weighing. A live fish conveyor line 7 for conveying the live fish to be weighed onto the weighing platform 6 is provided at one end of the weighing conveyor roller 5 and inside the weighing conveyor rack 2, realizing the conveyance of live fish onto the weighing platform 6 for weighing. A water trough 8 communicating with the water collection tank 3 is provided through the bottom side outside the weighing conveyor rack 2, which can collect and convey the accumulated water generated in the weighing conveyor trough to the water collection tank 3.

[0020] The end of the weighing platform 6 is evenly provided with strip-shaped grooves 9, so that the live fish conveyor belt 12 driven by the weighing conveyor roller 5 is at the same horizontal line as the surface of the weighing platform 6 during transmission. And a through cavity 10 is provided through the weighing support bottom plate of the weighing platform 6, which can allow the live fish conveyor belt 12 to pass through the weighing platform 6 for conveying and weighing, without affecting the weighing of live fish by the weighing platform 6. Inside the weighing conveyor frame 2 and at both ends of the weighing platform 6, there are rotating shaft rods 11, which drive the weighing conveyor rollers 5 to rotate, and the weighing conveyor rollers 5 are evenly arranged on the rotating shaft rods 11. Between the weighing conveyor rollers 5, there is a live fish conveyor belt 12 for conveying the live fish after weighing through the strip-shaped grooves 9 and the through cavity 10, so that the live fish conveyor belt 12 is kept horizontal with the weighing platform 6 during transmission, realizing synchronous conveying and weighing, and the live fish conveyor belt 12 remains in a transportation state.

[0021] One end of the rotating shaft of the live fish conveyor line 7 extends through to the outside and is connected to a servo motor 13 installed on the outside of one side of the weighing conveyor frame 2.
