Embodiment 1

[0027] In embodiment one, if figure 1 As shown, a net-lifting fishing gear for automatically catching and collecting fish, shrimps and crabs in partitions includes a net-lifting 1 and a net-lifting device 2, and also includes a collection cage 3, and a No. The fish passing channel 4, the No. 1 fish passing channel 4 is provided with a No. 1 inverted whisker 5 facing the collecting cage 3. When the lifting net 1 of embodiment 1 lifts the net under the effect of the net lifting device 2, the fish catch in the lifting net automatically enters the collection cage 3 through the No. 1 fish passage 4, and the lifting of the net and the collection of fish can be completed without manual labor. Material work, saving time and low labor costs. The collection cage 3 in the first embodiment is installed below the water surface, and lower than the lowest point of the lifting net 1, when the collection cage 3 is almost full, the collection cage 3 can be stretched out of the water surface; t...

Embodiment 2

[0037] In the second embodiment, if figure 2 As shown, the shrimp and crab bin 6 is a conical bin. The conical shrimp and crab bin 6 of embodiment two can further increase the difficulty for shrimp and crabs to enter the fish bin 7 .

Embodiment 3

[0038] In embodiment three or embodiment four, such as image 3 , Figure 4 Shown, described collection cage 3 is provided with dividing plate 10, and described dividing plate 10 constitutes shrimp and crab bin 6, and the other side constitutes fish bin 7, and described No. 2 fish passage 8 is arranged on the passageway on dividing plate 10. hole. The fish storehouse 7 and the shrimp and crab storehouse 6 are arranged side by side or up and down. The shrimp and crab bins 6 and the fish bins 7 of embodiments three and four adopt an integrated structure, which makes the collection cage 3 more compact in structure, and is also more convenient when lifted from the water.

Abstract

The invention discloses a drop net type fishing gear capable of realizing automatic fishing and fish, shrimp and crab collection in different regions, and is used for solving the problems of great work intensity and long time consumption of net hauling and fished object collection in the drop net fishing process. The drop net type fishing gear is characterized by comprising a drop net, a net hauling device and a collecting cage, wherein the collecting cage is arranged under the water surface; a No. 1 fish passing passage is arranged between the middle part of the drop net and the collecting cage; both an inlet and an outlet of the No. 1 fish passing passage are provided with reverse whiskers facing the collecting cage. When the drop net of the drop net type fishing gear is hauled under the effect of the net hauling device, fished objects in the drop net can automatically enter the collecting cage through the No. 1 fish passing passage; the work of net hauling and fished object collection can be completed without labor work; the time is saved; the labor cost is low.

Description

technical field [0001] The invention relates to the technical field of fishing gear and fishing, in particular to a lifting-net fishing gear for automatically catching and collecting fish, shrimps and crabs in sections. Background technique [0002] Lifting net is also called moving net. Lifting net fishing is to set the lifting net in advance and sink the net in the fishing waters, use light trapping, bait trapping, and then quickly lift the net to pocket the fish in the net to achieve the purpose of fishing. . The length and width of large-scale lifting nets are 20-40 meters or more. After sinking the nets, the fish in the net pockets are generally between several hundred catties to several thousand catties, and sometimes tens of thousands of catties. The harvesting has high labor intensity, long operation cycle, high labor cost, and it will take up more sinking time, which will affect the output. [0003] The utility model patent with the authorized announcement number ...
