[0003] The existing fish farming containers facilitate transportation and breeding, but losses still occur during transportation. After the fish farming container arrives at the destination, the fish inside the fish farming container need to be salvaged, but the dead fish need to be picked out during the salvage process, which seriously reduces the efficiency of fishing. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] An automatic fish catching device for a fish farming container includes a container body 1, a hydraulic cylinder 2 is fixedly connected to the outer surface of the container body 1, a lifting frame 3 is fixedly connected to the piston rod of the hydraulic cylinder 2, a motor 4 is fixedly connected to the surface of the lifting frame 3, a ball screw 5 is fixedly connected to the output shaft of the motor 4, a nut 6 is threadedly connected to the surface of the ball screw 5, a traction rope 7 is fixedly connected to the surface of the nut 6, a filter steel frame 8 is fixedly connected to the end of the traction rope 7 away from the nut 6, the filter steel frame 8 is provided with a filter hole for separating water and fish, and a guide is fixedly connected to the surface of the filter steel frame 8. Toward the track 9, a sliding plate 10 is slidably connected to the surface of the guide track 9, and an isolation filter 11 is fixedly connected to the surface of the sliding plate 10. The isolation filter 11 also has filtering holes for separating water and fish. The isolation filter 11 can be deformed by stretching, and an operating rod 12 is fixedly connected to the surface of the sliding plate 10. A limiting sleeve 13 is sleeved on the surface of the operating rod 12. The fish catching device can separate live fish from dead fish, avoids manual picking, and improves the efficiency of fish catching. All the fish are then fished out through the filtering steel frame 8 and placed on the ground for easy manual operation.

[0024] Furthermore, four groups of hydraulic cylinders 2 are provided, and two groups of lifting frames 3 are provided. The lifting frames 3 slide and rise and fall on the container body 1 through the piston rods of the hydraulic cylinders 2. The lifting levels of the two groups of lifting frames 3 are the same. During the lifting process of the lifting frames 3, the ball screws 5 and nuts 6 on the lifting frames 3 will also rise and fall synchronously.

[0025] Furthermore, a guide groove is provided on the surface of the lifting frame 3, and the ball screw 5 rotates on the guide groove of the lifting frame 3 through the output shaft of the motor 4. The nut 6 slides on the guide groove of the lifting frame 3 through the rotation of the ball screw 5. During the movement of the nut 6, the filter steel frame 8 will be driven to move through the traction rope 7, thereby changing the position of the filter steel frame 8.

[0026] Furthermore, the traction rope 7 is in a "V" shape, and the filter steel frame 8 is clamped on the inner surface of the container body 1. When the filter steel frame 8 is raised, the nut 6 supports the filter steel frame 8 through the traction rope 7. The traction rope 7 can be deformed. The filter steel frame 8 can be deformed at a certain angle through the traction rope 7. When the filter steel frame 8 is higher than the top of the container body 1, the traction rope 7 can be adjusted in angle.

[0027] Furthermore, the side of the isolation filter 11 away from the sliding plate 10 is fixedly connected to the filter steel frame 8. There are two groups of sliding plates 10 and isolation filter 11, and the two groups of sliding plates 10 can be contacted and connected together. The sliding plate 10 slides inside the filter steel frame 8 through the guide track 9. The sliding plate 10 changes the shape of the isolation filter 11 during the sliding process. The sliding plate 10 will initially be on both sides of the filter steel frame 8. When the two groups of sliding plates 10 are contacted and connected together, the isolation filter 11 is pulled into a plane, and the two groups of sliding plates 10 and the isolation filter 11 form a partition on the filter steel frame 8, thereby forming two spaces on the filter steel frame 8, the first space is for dead fish, and the second space is for live fish.

[0028] Furthermore, the height of the operating rod 12 is higher than the height of the container body 1, and the sliding plate 10 slides on the guide rail 9 through the operating rod 12, which makes it convenient to operate the operating rod 12 on the top of the container body 1. The position of the sliding plate 10 on the guide rail 9 can be changed through the operating rod 12, and then the shape of the isolation filter 11 can be adjusted.

[0029] Furthermore, the limit sleeve 13 is in an "0" shape, and the limit sleeve 13 is simultaneously sleeved on two groups of operating rods 12. The limit sleeve 13 limits the positions of the two groups of sliding plates 10 on the filter steel frame 8 through the operating rods 12, thereby ensuring the position of the sliding plate 10 on the guide rail 9, and further ensuring the partition formed by the sliding plate 10 and the isolation filter 11.

[0030] Working principle: a large amount of floating food is sprinkled on the upper surface of the container body 1. The live fish will be on the upper layer of the water surface of the container body 1, and the dead fish will fall on the surface of the filter steel frame 8. The sliding plate 10 is pulled to slide by the operating rod 12, so that the sliding plate 10 slides from the two sides of the filter steel frame 8 to the middle of the filter steel frame 8. At this time, the two groups of sliding plates 10 are in contact and connected together, and the limit sleeves 13 are sleeved on the two groups of operating rods 12, so that the operating rods 12 cannot operate the sliding plate 10 to slide on the guide rail 9 again. At this time, the sliding plate 10 and the isolation filter 11 isolate the dead fish on the bottom layer of the filter steel frame 8, while the live fish are still on the water surface. At this time, the fish can be caught. The plug rod drives the lifting frame 3 to rise and fall, and the lifting frame 3 drives the filter steel frame 8 to rise and fall through the traction rope 7, so that when the filter steel frame 8 rises to a level higher than the container body 1, the live fish inside the container body 1 are all loaded on the upper layer of the filter steel frame 8, and the ball screw 5 is driven to rotate by the output shaft of the motor 4. During the rotation, the ball screw 5 drives the nut 6 to slide on the lifting frame 3, and the nut 6 drives the filter steel frame 8 to one side of the container body 1 through the traction rope 7, so that the filter steel frame 8 and the container body 1 are misaligned. At this time, the filter steel frame 8 is tilted by the traction rope 7 to avoid contact between the filter steel frame 8 and the container body 1, and then the filter steel frame 8 is lowered to the ground to facilitate the staff to work.
