Embodiment 1

[0025] Such as Figure 1-5 Shown, the scheme that the present invention takes for realizing the above object is: a kind of large-area waters purse seine culture puller mechanical trapping device, comprises starting to catch machinery 6, grading temporarily raises pool 1, starts to catch machinery 6 one ends and support column 5 is connected, the other end below connects the catch frame 8 by the connecting rope 7, and the support column 5 side is provided with the intelligent feeding system 10, starts the catch frame 8, comprises the fixed disc 81, and the fixed disc 81 upper end is passed through the push rod 16 and The motor b15 output end that is installed in the lower end of the fishing machine 6 is connected, and the lower end of the fixed disk 81 is evenly distributed to connect the connecting rod 82, and the connecting rod 82 is connected to the surface of the rigid body frame 11 by the fishing net 83 ring cloth. By setting one end of the catching mechanism below and con...

Embodiment 2

[0033] Such as Figure 6-7 As shown, the optimization scheme of this embodiment on the basis of Embodiment 1 is: the rigid body frame 11 is connected with a netting 23, the inner surface of the netting 23 is uniformly connected with a buffer spring 24, and the end of the buffer spring 24 is connected with a silica gel sheet 25. The side of the silica gel sheet 25 near the net is provided with an outwardly inclined curved surface 26. By connecting and setting the net on the rigid frame, it can prevent the captured fish from escaping and slow down the impact of the water flow. The inner surface of the net is evenly connected with buffer springs. Through the setting of the spring, it can be pinched to the rigid frame. During the fish catching process, it can play a buffer role to reduce the damage caused by the fish colliding with the net. The end of the buffer spring is connected to the silica gel sheet. The side of the silica gel sheet near the net is provided with an arc surfa...

Embodiment 3

[0037] The working principle of the pulley mechanical trapping device for purse seine culture in large-area water area of ​​the present invention is as follows: firstly, the lifting net frame 8 will be sunk into the bottom of the water through the lifting mechanism 6, and then the intelligent feeding system 10 will be started to feed bait to attract a large number of fish. After grouping, start the motor b15 to make the push rod 16 drive the fixed plate 81 to rise, impel the fishing net 83 connected to the lower end of the connecting rod 82 to shrink, and prevent the fish in the rigid body frame 11 from escaping. Lifting, and under the action of the pulley 17 by the connecting rope 7, the net frame 8 is lifted to the water surface, and is temporarily raised in the grading holding pool 1, and by moving the grading grid 20, the grading holding pool 1 is temporarily raised. School of fish is screened, and the juvenile fish that screens out flows back in the waters by the fish retu...

Abstract

The invention discloses a mechanical catching device of a lifting net for enclosed netting culture in large water area. The device comprises a catching machine and a grading temporary culture pond, wherein one end of the catching machine is connected with a supporting column, the lower part of the other end of the catching machine is connected with a catching net rack through a connecting rope, one side of the supporting column is provided with an intelligent feeding system, and the catching net rack comprises a fixed disc; the upper end of the fixed disc is connected with the output end of amotor b arranged at the lower end of the catching machine through a push rod; connecting rods are uniformly distributed at the lower end of the fixed disc and connected with the surface of a rigid framework through fishing net ring cloth. The intelligent feeding system can intelligently put baits to attract a crowd of fishes and improve the fishing efficiency; the motor b runs to make the push rodmove forwards, the connecting rods uniformly distributed and connected at the lower end of the fixed disc are pushed to be spread outwards, and correspondingly a fishing net annularly distributed onthe surface of the rigid framework is pushed to extend outwards, so that the fishing water area is enlarged, and thus the fishing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aquatic products, in particular to a pulley mechanical trapping device for seine culture in large-area waters. Background technique [0002] At present, the seine aquaculture project urgently needs to focus on the development of fast and efficient fishing methods and devices in the case of seine aquaculture in large-area waters, so that it has high safety performance, is suitable for large-area seine aquaculture in shallow seas, and can greatly save costs cost. [0003] Shallow sea seine culture has a large area, no nets at the bottom, and the culture environment is closer to the natural ecology, but the feeding and catching methods of farmed fish are different from traditional cage culture, near-shore seine culture and marine fishing, so it is necessary to Carry out the research and development of special trapping facilities for deep-water seine farming, including sound and light trapping technology, fi...
