Problems solved by technology

[0002] At present, the traditional fishing methods are facing the following disadvantages: 1. Using pull nets to encircle, which takes a lot of time and manpower. In the current situation of high labor costs, the cost of fishing is greatly increased; 2. Fishing with traditional methods is easy to encounter underwater obstacles Scratching the fishing net will cause the fish to escape from the bottom and the fishing efficiency is low; 3. When fishing in hot weather, it is difficult to manually sort the size and specification, and because the operation time is too long, the fish are prone to stress death; 4. In winter One-time fishing in dry reservoirs, because the relatively low price of commercial fish on the market affects the improvement of economic benefits

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The structure of the fish trapping device provided by the invention is as figure 1 As shown, the device comprises a fixed pile 1, a pulley mechanism, a hoist 16, a bait thrower 14, a food table 13, a fixed cable 3, a lifting net 4, a cage net 11, a funnel net A6, a funnel net B10, a moso bamboo stand 5, and a moso bamboo 7. Entrance net 12 and net box 9 for collecting fish. Fixed pile 1, fixed cable 3, winch 16, pulley mechanism all have two, and moso bamboo 3.

[0021] The pulley mechanism comprises a pulley 2 and a sling 15, two pulleys 2 are fixed on two fixed piles 1 respectively, and two slings 15 are wound on the two pulleys 2 respectively. In this embodiment, the slings are 10#PE ropes, each with a length of 20m.

[0022] The lifting net 4 is square, and the lifting net has an A side 17 and a B side 18 , and the A side 17 is parallel to the B side 18...

Abstract

The invention discloses a fish trapping device which comprises two winches, two fixing piles, two fixing ropes, two pulley mechanisms, a bait feeder, a feed platform, a drop net, an entrance net, a basket net, a funnel net A, a funnel net B and a fish collection net cage, wherein two pulleys of the two pulley mechanisms are fixed on the two fixing piles respectively, the drop net is square, and is provided with a side A and a side B, the two corners of the side A are connected with the two winches through the two pulley mechanisms respectively, the entrance net takes the shape a quadrangular platform, the large port of the entrance net is provided with a side C and a side D, the side D is sewn and fixed with the side B, the two corners of the side C are fixed on the two fixing piles through the fixing ropes respectively, the basket net is divided into a front-section net body, a middle-section net body and a rear-section net body, the front-section net body is sewn and fixed with the entrance net, the funnel net A is mounted on the front-section net body, the middle-section net body is a screen, the funnel net B is mounted on the rear-section net body, the inlet of the fish collection net cage is in butt joint with the small port of the funnel net B. The device is simple in structure and ingenious in design, and when being used for fishing, the device is low in labor intensity.

Description

technical field [0001] The invention belongs to the technical field of fishing equipment, and in particular relates to a fish trapping device. Background technique [0002] At present, the traditional fishing methods are facing the following disadvantages: 1. Using pull nets to encircle, which takes a lot of time and manpower. In the current situation of high labor costs, the cost of fishing is greatly increased; 2. Fishing with traditional methods is easy to encounter underwater obstacles Scratching the fishing net will cause the fish to escape from the bottom and the fishing efficiency is low; 3. When fishing in hot weather, it is difficult to manually sort the size and specification, and because the operation time is too long, the fish are prone to stress death; 4. In winter The one-time fishing in the dry storage of the water release will affect the improvement of economic benefits due to the relatively low price of commercial fish on the market.
