[0068] It should be understood that the fish suction mechanism 2 is started in the first box 1, and the negative pressure principle is used to attract the fish from the outside and guide them into the first box 1; the first box 1 is designed to be sealed to ensure that the pressure environment during the fish suction process is stable and to prevent the fish from being disturbed or harmed by the outside world; when the fish are sucked into the first box 1, they will contact the filter plate 7; the design of the filter plate 7 allows water and dirt to pass through, and the fish will be blocked by the filter plate 7; at this time, the first electromagnetic valve 11 is opened and connected to one end of the filter plate 7, so that the fish after the water and dirt are filtered can slide to the first electromagnetic valve 11 according to the inclination of the filter plate 7 to flow into the second box 3 for subsequent classification and weighing and counting; the fish entering the second box 3 then encounters the classification mechanism 4; the classification mechanism 4 may Fish schools are divided into large fish schools, medium fish schools and small fish schools; this process is carried out based on the size of the fish schools; the classified large fish schools, medium fish schools and small fish schools fall into the corresponding counting and weighing mechanisms 5 respectively; these mechanisms use sensor technology to accurately measure the weight of large fish schools, medium fish schools and small fish schools, and count the number of large fish schools, medium fish schools and small fish schools respectively; the counting and weighing mechanisms 5 are connected to the inner wall of the second box body 3 to ensure stable and accurate measurement; finally, after all the initial fish schools have been sorted, counted and weighed, and the weights and numbers of large fish schools, medium fish schools and small fish schools are obtained respectively, the large fish schools, medium fish schools and small fish schools are respectively guided to the corresponding fish holding mechanisms 6; the fish holding mechanisms 6 can adopt a container design that is easy to clean and move to facilitate subsequent processing or transportation.

[0069] Furthermore, the fish suction mechanism 2 includes a second electromagnetic valve 21, a fish suction tube 22, a guide member 23, an air suction hole 24, an air pump 25, an air suction pipe 26 and a ventilation valve 27; wherein, the second electromagnetic valve 21 is arranged on the side wall of the first box body 1, and the second electromagnetic valve 21 is rotatably connected to the first box body 1; the fish suction tube 22 is connected to one end of the second electromagnetic valve 21 located outside the first box body 1; the guide member 23 is connected to one end of the second electromagnetic valve 21 located inside the first box body 1; the air suction hole 24 is arranged on the first box body 1; the air pump 25 is arranged at the bottom of the first box body 1; one end of the air suction pipe 26 is connected to one end of the air suction hole 24 located outside the first box body 1, and the other end is connected to the air suction pump 25; the ventilation valve 27 is arranged on the first box body 1.

[0070] It should be understood that, based on the above definition, when it is necessary to suck fish, the second electromagnetic valve 21 is first opened to allow the fish suction tube 22 to communicate with the interior of the first box body 1; at the same time, the air pump 25 starts to work, and draws air from the interior of the first box body 1 through the air suction tube 26 and the air suction hole 24, thereby forming a negative pressure area between the fish suction tube 22 and the interior of the first box body 1; due to the effect of the negative pressure, the fish in the external water source are attracted and enter the first box body 1 through the fish suction tube 22; the guide member 23 is located at the end where the second electromagnetic valve 21 is connected to the interior of the first box body 1, and its design helps to guide the fish to smoothly The air in the air pump 25 stops working, the second electromagnetic valve 21 is closed, and the connection between the fish suction pipe 22 and the first box body 1 is cut off; the first electromagnetic valve 11 is opened, and the fish flow from the filter plate 7 through the first electromagnetic valve 11 into the second box body 3 for subsequent classification, counting, weighing and packaging.

[0071] It should be noted that, through the cooperation of the vacuum pump 25 and the negative pressure, the fish suction mechanism 2 can efficiently suck the fish from the external water source into the first box 1, greatly improving the fish suction efficiency; the setting of the second electromagnetic valve 21 and the ventilation valve 27 makes the fish suction process more stable and reliable; the various components of the fish suction mechanism 2 are reasonably designed and easy to disassemble and clean, reducing maintenance costs and time; by adjusting the working parameters of the vacuum pump 25, the fish suction mechanism can adapt to fish of different types and sizes, improving the versatility and flexibility of the equipment.

[0072] Furthermore, the classification mechanism 4 includes a transmission rod 41 and a conveyor belt 42; wherein, both ends of the multiple transmission rods 41 are rotatably connected to the inner wall of the second box body 3; the conveyor belt 42 is sleeved on both ends of the transmission rod 41, and the transmission belt 42 rotates to drive the transmission rod 41 to rotate on the inner wall of the second box body 3; the classification mechanism 4 is divided into a first classification part 43, a second classification part 44 and a third classification part 45 according to the distance between the transmission rods 41, and the distances between the transmission rods in the first classification part 43, the second classification part 44 and the third classification part 45 increase successively; the first classification part 43 is located at one end of the second box body 3 close to the first solenoid valve 11.

[0073] It should be understood that, based on the above definition, when the fish enter the second box 3 through the first electromagnetic valve 11, they will fall on the transmission rod 41; at this time, the conveyor belt 42 starts to rotate, and the transmission rod 41 is driven to rotate in the second box 3 by friction, thereby driving the fish to move along the direction of rotation of the conveyor belt 42; the fish first pass through the first classification part 43, and the distance between the transmission rods 41 of the first classification part 43 is the smallest, so only small fish can be allowed to pass through and fall into the counting and weighing mechanism 5 below. As the conveyor belt 42 rotates, the fish continue to move, and the medium fish will fall into the counting and weighing mechanism 5 of the fish below the second classification part 44; finally, the large fish will pass through the gap between the transmission rods of the third classification part 45 and be guided to the large fish counting and weighing mechanism 5 below the third classification part 45; the continuous rotation of the conveyor belt 42 ensures the continuous classification and output of the fish; each classification part corresponds to a specific size range of the fish, thereby achieving accurate classification of the fish.

[0074] It should be noted that, through the cooperation of the conveyor belt 42 and the transmission rod 41, the classification mechanism 4 can efficiently classify the fish by size and transport them to the corresponding counting and weighing mechanism 5; the design of the classification mechanism 4 enables the transmission rod distance between each classification part to be precisely controlled, thereby ensuring the accuracy of fish classification; by adjusting the distance between the transmission rods, the classification mechanism 4 can adapt to the classification needs of fish of different sizes and types, thereby improving the versatility and flexibility of the equipment; the entire classification process is completed by the automatic rotation of the conveyor belt and the transmission rod, without the need for human intervention, which greatly improves the automation level and work efficiency of the equipment.

[0075] Furthermore, three counting and weighing mechanisms 5 are respectively arranged below the first classification part 43, the second classification part 44 and the third classification part 45;

[0077] It should be understood that, based on the above definition, the fish shoals classified by the classification mechanism 4 fall into the corresponding weighing boxes 51 below the first classification part 43, the second classification part 44 and the third classification part 45 respectively; the top opening design of the weighing box 51 allows the fish shoals to fall in smoothly, and the inclined design of the bottom from both sides to the middle helps the fish shoals to slide smoothly to the third electromagnetic valve 52 at the bottom; when the fish shoals fall into the weighing box 51, multiple pairs of photoelectric counting sensors 53 start working, and the number of fish shoals is accurately counted by detecting the light blocking situation when the fish shoals pass through the sensors. ; At the same time, a weight sensor is buried at the bottom of the weighing box 51 to measure the total weight of the fish that fall into the school in real time; after weighing and counting are completed, the third electromagnetic valve 52 opens to allow the fish in the weighing box 51 to pass through and fall into the fish holding mechanism 6 below; the inclined design of the bottom of the weighing box 51 ensures that the fish can slide out smoothly under the action of gravity, avoiding blockage or retention; the sensor data in the counting and weighing mechanism 5, including the number of fish and the total weight, can be recorded and output in real time through the connected data recording system, providing an accurate basis for subsequent processing, sales or data analysis.

[0078] It should be noted that the combined use of the photoelectric counting sensor 53 and the weight sensor ensures the accurate measurement of the number of fish and the total weight, and improves the accuracy of the data; the inclined design of the bottom of the weighing box 51 and the cooperation of the third electromagnetic valve 52 enable the fish to be quickly and smoothly output to the fish holding mechanism 6 after weighing and counting are completed, thereby improving the overall working efficiency of the equipment.

[0079] Furthermore, it also includes a moving mechanism 8, which is arranged at the bottom of the first box body 1 and the second box body 3 and is used for moving the fish grading, weighing and counting device.

[0080] It should be understood that, based on the above definition, when the fish grading, weighing and counting device needs to be moved, the operator can achieve this by controlling the moving mechanism 8; after the moving mechanism 8 starts working, it will drive the entire device to move smoothly on the ground or other supporting surfaces;

[0081] Furthermore, the moving mechanism includes four universal wheels 81 , and two universal wheels 81 are respectively arranged at the bottom of the first box body 1 and the bottom of the second box body 3 .

[0082] It should be understood that, based on the above definition, the universal wheel has the ability to rotate 360 ​​degrees, which means that the equipment can be easily moved in any direction without additional steering operations; this feature is particularly useful in narrow or crowded spaces because it allows the operator to move the equipment with a minimum turning radius; two universal wheels are installed at the bottom of the first box 1 and the second box 3 to ensure the balance and stability of the equipment when moving; this distribution method also helps to disperse the weight of the equipment and reduce the burden on a single wheel, thereby extending the service life of the wheel; the material of the universal wheel is usually selected from wear-resistant and durable materials such as rubber or hard plastic to ensure sufficient grip and wear resistance under various ground conditions; in terms of size, according to the weight and size of the equipment, select a suitable wheel diameter and width to ensure sufficient load-bearing capacity and stability.

[0083] It should be noted that the design of four universal wheels enables the fish grading, weighing and counting device to be easily moved in various environments, whether it is flat ground or uneven ground, and can achieve fast and efficient movement; the 360-degree rotation feature of the universal wheel enables the equipment to easily adapt to various complex moving paths and turning requirements, greatly improving the flexibility of the equipment; by installing universal wheels, the operator can easily push or pull the equipment without expending too much physical effort, thereby reducing the operating burden.

[0084] Furthermore, three fish holding mechanisms 6 are respectively arranged below the third electromagnetic valves 52 of the three weighing boxes 51 , and the fish holding mechanisms 6 include fish holding barrels 61 ; wherein the fish holding barrels 61 are placed on the inner bottom wall of the second box body 3 .

[0085] It should be understood that, based on the above-mentioned definitions, the core component of the fish holding mechanism 6 is the fish bucket 61, which is firmly placed on the inner bottom wall of the second box body 3; the material of the fish bucket is usually corrosion-resistant and easy-to-clean material, such as stainless steel or high-density polyethylene, to ensure the hygiene and safety of the fish; the capacity of the fish bucket is carefully designed to accommodate the fish from the corresponding classification department; the design of the fish bucket also takes into account the convenience of operation; for example, the bucket wall can be designed to be inclined to facilitate the smooth sliding in and out of the fish; in addition, the bottom of the bucket can be equipped with rollers or sliding devices so that the fish bucket can be easily moved or carried when needed.

[0086] Furthermore, a box door 31 is rotatably provided on the upper side wall of the second box body 3 , and the box door 31 is located at a position on the second box body 3 corresponding to the fish holding mechanism 6 .

[0087] It should be understood that, based on the above limitations, the setting of the box door 31 allows the operator to easily open or close it, so that the fish holding mechanism 6 can be easily removed from the second box body 3, and the box door 31 can be opened to observe the fish school in the fish holding mechanism 6, or to perform necessary operations, such as cleaning, maintenance or adjustment of the fish barrel 61; when observation and operation are not required, the box door 31 can remain closed to prevent interference and pollution from the external environment and protect the hygiene and safety of the fish.

[0088] Furthermore, a drainage hole 12 is provided at the bottom of the side wall of the first box body 1 .

[0089] It should be understood that, based on the above definition, the main function of the drain hole 12 is to remove the filtered water and dirt after the fish in the first box body 1 are filtered by the filter plate 7. If these water accumulates in the first box body for a long time, it may cause the equipment to be damp, rusty or breed bacteria, affecting the hygienic performance and service life of the equipment; these excess water can be discharged in time to keep the first box body clean; the drain hole also helps to prevent water from contaminating the fish. If too much water accumulates in the first box body, this water may come into contact with the fish, causing the fish to deteriorate or be contaminated. By setting up the drain hole, the risk of such pollution can be reduced; the setting of the drain hole also facilitates the maintenance and maintenance of the equipment. When cleaning or maintaining the equipment, the cleaning liquid or sewage can be discharged through the drain hole, making the equipment easier to clean and maintain.

[0090] Furthermore, the first box body 1 and the second box body 3 are made of stainless steel.

[0091] It should be understood that, based on the above definition, stainless steel has excellent corrosion resistance and can resist erosion by a variety of chemicals such as water, acid, alkali, etc. This is particularly important for fish processing equipment, because the equipment may come into contact with various liquids during use, including fish body fluids, cleaning fluids, etc. Stainless steel has high strength and durability and can withstand greater mechanical stress and impact. This makes the equipment more durable and able to withstand the wear and impact of daily use. The surface of stainless steel is smooth and does not easily accumulate dirt and bacteria. This makes the equipment easier to clean and maintain, helping to maintain the hygienic performance of the equipment. Stainless steel has a modern and beautiful appearance, which can enhance the overall visual effect of the equipment.
