Description

Technical Field

[0001] The utility model relates to the field of fish sorting equipment, in particular to a device for fish sorting. Background Art

[0002] Current fish sorting equipment generally uses two main sorting methods: weight sorting and size sorting. The equipment used for the weight sorting method typically consists of two main components: a weighing conveyor and a sorting conveyor. In this equipment, the fish to be sorted first pass through the weighing conveyor for weight measurement, and then enter the sorting conveyor for sorting. The sorting conveyor is designed with multiple fish outlets, each equipped with a swing arm. When a fish is about to reach a preset outlet, the swing arm rotates open precisely to intercept the fish, and then rotates closed to sweep the fish into the corresponding outlet.

[0003] The system works like this: a weighing conveyor records the weight of every passing fish and transmits this information in real time to a controller. Based on multiple parameters, including the conveyor's speed, the time when fish enter and exit the weighing conveyor, the distance between the fish outlet and the conveyor exit, and the opening, waiting, and closing times of the swing arm, the controller calculates the time required to sort fish of different weights to the pre-set outlets. It then precisely controls the opening and closing times of the swing arm at the corresponding outlets.

[0004] Although this equipment has made outstanding contributions in the field of fish sorting, due to its inherent design limitations, the sorting efficiency still has room for improvement. In particular, the design of the swing arm, because one end is fixed as the axis and the other end swings, there is a limit to the time it takes for the swing arm to open and stop. If you try to shorten this limit, the swing arm will swing too fast, and due to inertia, the swing arm will oscillate violently or even break. Similarly, there is a limit to the time it takes for the swing arm to close from waiting. Shortening this time may cause the fish to be swept away, or the huge reaction force generated by the swing arm's instantaneous impact on the fish may cause damage to the swing arm mechanism. It is these limitations that make it difficult to further speed up the sorting process.

[0005] Therefore, in order to speed up the sorting process, the sorting device on the sorting belt needs to be redesigned. Utility Model Content

[0006] The purpose of the utility model is to provide a device for sorting fish, so as to solve the problems described in the background technology.

[0007] The technical solution of the present utility model is achieved as follows:

[0008] A device for sorting fish comprises a controller, a weighing and conveying component and a sorting conveyor belt connected to the weighing and conveying component, a plurality of mounting frames are provided on the left and right sides of the sorting conveyor belt, the mounting frames are provided with side baffles extending to the top of the sorting conveyor belt, the side baffles on different mounting frames on the same side are spaced apart from each other to form a plurality of fish outlets, the number of fish outlets on the left and right sides is the same and they are symmetrically arranged one by one, a sorting device is also provided above the sorting conveyor belt, the sorting device comprises a front pointed-edge cone plate arranged just above the sorting conveyor belt and a plurality of active fish sorting mechanisms, the front pointed-edge cone plate is connected to the mounting frame with the pointed edge facing forward, the rear end of the front pointed-edge cone plate is respectively clamped with the side baffles on the left and right sides to form an output channel, and the active fish sorting mechanism is arranged at intervals behind the front pointed-edge cone plate. The active fish sorting mechanism includes a bracket and an automatic push rod arranged on the bracket, the telescopic rod of the automatic push rod extends downward and is connected to an active fish sorter, the active fish sorter is arranged between two fish outlets symmetrically arranged on the left and right, the active fish sorter includes an active pointed-edge cone plate connected to the telescopic rod and fish baffles arranged on both sides below the rear end of the active pointed-edge cone plate, the pointed edge of the active pointed-edge cone plate faces forward, and the rear end of the active pointed-edge cone plate extends to the fish outlet, and the fish baffles are arranged on the left and right sides of the sorting conveyor belt, when the telescopic rod extends downward by a certain length, the fish baffle is lower than the upper end surface of the sorting conveyor belt and exposes the fish outlet, when the telescopic rod retracts upward by a certain length, the fish baffle is higher than the upper end surface of the sorting conveyor belt and blocks the fish outlet, and the weighing transmission component and the automatic push rod are both electrically connected to the controller.

[0009] When using the above solution, the fish are placed on the weighing conveyor component for weighing, and the corresponding information is recorded and transmitted to the controller. When the fish leave the weighing conveyor component and enter the sorting conveyor belt, the fish are first diverted to the left and right edges of the sorting conveyor belt by the front pointed cone plate and discharged from the output channel. They flow backward with the sorting conveyor belt. The side baffles can effectively prevent the fish from falling from the left and right edges of the sorting conveyor belt.

[0010] When a fish enters the preset fish outlet, the controller controls the telescopic rod of the automatic push rod to extend downward, the active pointed-edge cone plate to move downward to interfere with and guide the flow of the fish, and the fish-blocking plate to move downward to expose the fish outlet. Since the fish is already at the edge of the sorting conveyor belt, when the fish encounters the active pointed-edge cone plate during its backward flow, it can be quickly guided out of the fish outlet. After the fish exits the fish outlet (i.e., after the active pointed-edge cone plate moves down and stays for a predetermined period of time), the controller controls the telescopic rod of the automatic push rod to retract upward, causing the active pointed-edge cone plate to move up, and the fish-blocking plate to move up as well. This prevents the active pointed-edge push rod from interfering with subsequent fish and also blocks the fish outlet, preventing the fish from falling into an outlet that does not belong to it.

[0011] Because the active pointed-edge cone plate moves up and down, the bottom of the active pointed-edge cone plate does not need to reach close to the upper end of the sorting conveyor belt when it moves downward to guide the fish. As long as the bottom of the active pointed-edge cone plate is at a certain distance from the upper end of the sorting conveyor belt, the active pointed-edge cone plate can still interfere with the flow of fish and guide them to the fish outlet. This shortens the displacement of the active pointed-edge cone plate, which reduces the time required, and reduces the time required for sorting, effectively speeding up the sorting process. Furthermore, the active pointed-edge cone plate's displacement is a reciprocating motion, allowing it to start and stop quickly without experiencing bending forces. This also eliminates the concerns associated with swing-arm motion.

[0012] A further technical solution is that the front pointed-edge cone plate includes two long front rectangular plates, both of which are perpendicular to the upper end surface of the sorting conveyor belt, and the front ends of the two front rectangular plates intersect and are fixedly connected to form an acute angle, and the front ends of the two front rectangular plates together form the pointed edge of the front pointed-edge cone plate.

[0013] A further technical solution is that the active pointed-edge cone plate includes two long rear rectangular plates, both of which are perpendicular to the upper end surface of the sorting conveyor belt, and the front ends of the two rear rectangular plates intersect and are fixedly connected to form an acute angle. The front ends of the two rear rectangular plates jointly form the pointed edge of the active pointed-edge cone plate, and the tops of the two rear rectangular plates are also connected by a first connecting rod. The first connecting rod is also provided with a connecting plate for connecting to the telescopic rod of the automatic push rod. The active fish separator also includes two second connecting rods, which are respectively connected to the rear ends of the two rear rectangular plates, and the second connecting rod extends downward, and the fish baffle is connected to the second connecting rod.

[0014] A further technical solution is that the bracket includes support frames arranged on the left and right sides of the sorting conveyor belt, and a horizontal frame is also arranged on the top of the support frame and is located directly above the sorting conveyor belt, and the automatic push rod is installed on the horizontal frame.

[0015] A further technical solution is that the automatic push rod includes a pneumatic push rod and a multi-position multi-way solenoid valve, the multi-position multi-way solenoid valve is connected to the pneumatic push rod, and the multi-position multi-way solenoid valve is electrically connected to the controller.

[0016] A further technical solution is that a plurality of first support rods are connected to the side of the mounting frame facing the sorting conveyor belt, and the side baffles are connected to the ends of the first support rods.

[0017] A further technical solution is that the upper end of the front rectangular plate of the front pointed-edge cone plate is further fixedly connected to the mounting frames on the left and right sides of the front pointed-edge cone plate through a second support rod.

[0018] A further technical solution is that a plurality of fish storage barrels with upper ends opened are provided on the left and right sides of the sorting conveyor belt. The fish storage barrels are arranged at the fish outlet. The upper end openings of the fish storage barrels are lower than the upper end surface of the sorting conveyor belt. The fish baffle is arranged between the sorting conveyor belt and the fish storage barrels.

[0019] A further technical solution is that a discharge port is provided at the bottom of the side wall of the fish storage barrel.

[0020] A further technical solution is that the weighing and conveying component includes a weighing device and a weighing conveyor belt arranged on the weighing device, the weighing device is electrically connected to the controller, and the sorting conveyor belt is connected to the weighing conveyor belt.

[0021] The beneficial effects of the present invention are:

[0022] 1. Efficient diversion and guidance: This solution achieves efficient fish diversion and guidance through the effective cooperation of the front sharp-edged cone plate and the active sharp-edged cone plate. The front sharp-edged cone plate diverts the fish to the left and right edges of the sorting conveyor belt, paving the way for subsequent rapid sorting.

[0023] 2. Automatic control: Through the precise control of the controller and automatic push rod, the active pointed edge cone plate can be automatically moved up and down, thereby accurately controlling the flow direction of fish and the opening and closing of the fish outlet, improving the accuracy and efficiency of sorting.

[0024] 3. Anti-fall design: The design of the side baffles and fish baffles effectively prevents fish from falling from the left and right edges of the sorting conveyor belt and accidentally falling into non-fish outlets, ensuring the safety and stability of the sorting process.

[0025] 4. Fast sorting rhythm: Since the active pointed edge cone plate adopts an up and down motion mode, its displacement is short and the time is short, thus speeding up the sorting rhythm. This design not only improves work efficiency, but also makes the entire sorting process smoother.

[0026] 5. Eliminates concerns about swing arm movement: The active pointed-edge cone plate adopts an up and down reciprocating motion. Compared with the swing arm motion, its rapid start and stop will not be affected by the bending force, thus eliminating the mechanical failure problem that may be caused by the swing arm motion.
