Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a fish sorting device. Background Technology

[0002] Fish size sorting device is an automated device for grading fish by size. It is mainly used in aquaculture, processing and distribution. It can quickly separate fish of different sizes according to their body length, weight and other size indicators, and achieve efficient grading.

[0003] During aquaculture, the different breeding cycles of fish result in different body sizes. When screening fish in the breeding pond, it is necessary to filter out smaller fish that have not fully developed. Traditional screening methods cannot transfer the screened fish after filtering. To facilitate subsequent screening operations, a fish sorting device is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a fish sorting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fish sorting device, comprising a breeding pond, wherein a pair of fixed plates and a support plate are fixedly connected to the inner wall of the breeding pond, a first electric telescopic rod is fixedly connected to the upper surface of the fixed plate, a second electric telescopic rod is fixedly connected to the upper surface of the support plate, a storage box is fixedly connected to the upper surface of the breeding pond, a sieve is installed inside the breeding pond, a friction plate is fixedly connected to the surface of the sieve, and an attraction and screening mechanism is provided on the inner wall of the storage box.

[0006] Preferably, the inducing and screening mechanism includes a rotating rod rotatably connected to the inner wall of the storage box, a friction wheel fixedly connected to the surface of the rotating rod, a ratchet fixedly connected to the surface of the rotating rod, a discharge groove opened on the surface of the rotating rod, and the position of the friction wheel corresponding to the position of the friction plate.

[0007] Preferably, a spring is fixedly connected to the surface of the storage box, and a pawl is fixedly connected to one end of the spring, with the surface of the pawl rotatably connected to the surface of the storage box.

[0008] Preferably, the inner wall of the fixing plate is slidably connected to a first slider, the inner wall of the support plate is slidably connected to a second slider, the inner wall of the first slider is rotatably connected to a first ball head, and the inner wall of the second slider is rotatably connected to a second ball head.

[0009] Preferably, the surface of the sieve mesh is fixedly connected to the surface of the second ball head, and a sliding plate is slidably connected to the lower surface of the sieve mesh, with one end of the sliding plate fixedly connected to the surface of the first ball head.

[0010] Preferably, a controller is fixedly installed on the surface of the aquaculture pond, a drain pipe is fixedly connected to the inner wall of the aquaculture pond, and a valve is fixedly installed on the surface of the drain pipe.

[0011] In summary, the technical effects and advantages of this utility model are as follows: In this invention, when the screen rises, the pawl limits the rotation of the ratchet wheel to prevent the friction wheel from reversing. When the screen tilts, the fish on the screen are discharged to the outside. After being transferred, when the screen descends, the surface of the friction plate contacts the surface of the friction wheel, causing the ratchet and the rotating roller to rotate. The rotating roller rotates the discharge trough, which discharges the fish feed from the storage box. The fish inside the breeding pond will float to the surface to feed. At this time, during the process of the screen descending and resetting, the fish will swim out through the filter screen on the screen. The advantage of this is that it is convenient to perform screening operations again after the fish grows up. Attached Figure Description

[0019] By setting the friction wheel 12, when the friction plate 10 moves and comes into contact with the surface of the friction wheel 12, it drives the friction wheel 12 to rotate, and the residual material is discharged by setting the discharge chute 11.

[0020] Preferably, a spring 13 is fixedly connected to the surface of the storage box 6, and a pawl 14 is fixedly connected to one end of the spring 13. The surface of the pawl 14 is rotatably connected to the surface of the storage box 6.

[0021] By setting spring 13, the pressure on pawl 14 is kept stable, and by setting pawl 14, the ratchet 15 and rotating rod 9 are prevented from reversing as a whole.

[0023] The first ball head 19 is installed and positioned by setting the first slider 20, and the second ball head 17 is installed and positioned by setting the second slider 16.

[0024] Preferably, the surface of the sieve 8 is fixedly connected to the surface of the second ball head 17, and a sliding plate 18 is slidably connected to the lower surface of the sieve 8, with one end of the sliding plate 18 fixedly connected to the surface of the first ball head 19.

[0025] By setting the sliding plate 18, when the screen 8 is tilted, the sliding plate 18 slides on the lower surface of the screen 8 to provide support and avoid obstacles.

[0026] Preferably, a controller 7 is fixedly installed on the surface of the aquaculture pond 1, a drain pipe 21 is fixedly connected to the inner wall of the aquaculture pond 1, and a valve 22 is fixedly installed on the surface of the drain pipe 21.

[0027] By setting the controller 7, an electrical signal is sent to control the PLC to control the synchronous start and stop of the first electric telescopic rod 5 and the second electric telescopic rod 4.

[0028] The working principle of this utility model is as follows: A fish sorting device is provided. A controller 7 and a power supply are installed on the surface of the breeding pond 1. The controller 7 is used to control the driving equipment (electric telescopic rod), and the power supply provides power to the driving equipment. In use, the controller 7 is operated to start the synchronous movement of the output ends of the first electric telescopic rod 5 and the second electric telescopic rod 4, which respectively drive the first slider 20 to slide in the fixed plate 2 and drive the second slider 16 to slide in the support plate 3. The first slider 20 and the second slider 16 rise synchronously, driving the screen 8 to move upward. The screen 8 rises and conveys the fish raised in the breeding pond 1 upward. Unqualified fish will be filtered through the filter screen on the screen 8. When the surface of the friction plate 10 contacts the surface of the friction wheel 12, the pawl 14 limits the rotation of the ratchet 15, preventing the friction wheel 12 from rotating. 2. When the second slider 16 moves to the highest point and stops, the first slider 20 continues to rise, causing the screen 8 to tilt under force. At this time, the sliding plate 18 slides on the lower surface of the screen 8, and the second ball head 17 rotates inside the second slider 16 for adjustment. The screen 8 tilts and discharges the fish on the screen 8 to the outside. After the fish are transferred, the screen 8 is driven to descend and reset. During the descent of the screen 8, the surface of the friction plate 10 contacts the surface of the friction wheel 12, causing the ratchet 15 and the rotating roller 9 to rotate. The rotating roller 9 rotates and drives the discharge trough 11 to rotate. The discharge trough 11 discharges the fish feed in the storage box 6. The fish inside the breeding pond 1 will float to the surface to eat. At this time, during the descent and reset of the screen 8, the fish will swim out through the filter screen on the screen 8, making it convenient for the fish to be screened again after they grow up.
