Description

Shrimp catching device

Technical Field

The invention relates to the field of aquatic product cultivation, in particular to a shrimp catching device.

Background

The shrimps like to live in the area with more aquatic weeds and riprap at the river bottom can not be caught by large nets generally. At present, people generally adopt a circular net sheet when catching shrimps, and the net sheet is provided with a circular framework. When the shrimp catching net is used, the shrimp trapping food is put in the center of the circular net piece and is put in water, when shrimps enter the center of the circular net piece to eat, the net is lifted, the shrimps remained in the circular net piece are caught, however, in the process of lifting the net piece, some shrimps escape from the monster and the monster due to the fact that the circular net piece moves, the shrimps escaping due to the missed catching are frightened, the normal growth of the shrimps is influenced, if the circular net piece is not lifted in time, some full shrimps swim away, the shrimp trapping food is wasted, the labor intensity is high, the shrimp catching amount is small, and the shrimp catching effect is poor. Also someone begins to use the shrimp cage that has interior inverted whisker structure, and the bore of interior inverted whisker structure is big end before, little, comes in and goes out easily difficultly, but uses such shrimp cage needs certain shrimp catching experience, need lift the shrimp cage from the aquatic at suitable opportunity, because the shrimp in the shrimp cage can go out from the structural little export of interior inverted whisker after food has eaten, the shrimp catching effect is poor. Therefore, a new technical solution is needed.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

As shown in figure 1, the invention provides a shrimp catching device which comprises a cage body 1, wherein a shrimp taking port 2 is formed in the side wall of the cage body 1, a sealing device is arranged on the shrimp taking port 2, the cage body 1 comprises a framework 11 and a net piece 12 covering the framework 11, first shrimp inlets 13 are formed in the net piece 12 at two ends of the cage body 1 respectively, the first shrimp inlets 13 are communicated with a shrimp inlet channel 14 respectively, one ends of the shrimp inlet channels 14, which are far away from the first shrimp inlets 13, are provided with second shrimp inlets 15 respectively, shrimps enter the shrimp inlet channel from the first shrimp inlets, and the shrimps enter the cage body from the second shrimp inlets after passing through the shrimp inlet channel.

As shown in fig. 1, in this embodiment, a food holding device 3 is disposed in the cage body 1, the food holding device 3 includes a first holding member 31 and a second holding member 32 that are close to or far away from each other, the food is held between the first holding member 31 and the second holding member 32, the first holding member 31 and the second holding member 32 are respectively connected to one end of a connecting rope 4, the other end of the connecting rope 4 respectively penetrates through the net sheet 12 and the shrimp inlet passage 14 and is connected to a cover plate 5, and the cover plate 5 can close the second shrimp inlet 15. As the shrimps eat food slowly, the first clamping piece 31 and the second clamping piece 32 approach gradually, and in the process that the first clamping piece 31 and the second clamping piece 32 approach gradually, the first clamping piece 31 and the second clamping piece 32 respectively pull up the cover plate 5 through the connecting rope 4 to cover the second shrimp inlet 15, so that the shrimps cannot escape from the cage body 1 through the second shrimp inlet 15.

As shown in fig. 1, in the present embodiment, the cross-sectional area of the shrimp intake passage 14 gradually decreases in a direction from the distance to the proximity of the second shrimp intake port 15. Therefore, the first shrimp inlet 13, the shrimp inlet channel 14 and the second shrimp inlet 15 form an inward-inverted beard structure, and the aperture is large in the front and small in the rear, so that the shrimps entering the shrimp cage are difficult to find the second shrimp inlet 15.

In this embodiment, as shown in fig. 1, the second shrimp intake 15 is connected to the frame 11 by a diagonal member. This may increase the structural strength of the shrimp passage 14.

As shown in fig. 1, in this embodiment, the closure device is a zipper. Therefore, the shrimps can be conveniently taken.

As shown in fig. 1, in the present embodiment, the first clamping member 31 and the second clamping member 32 are both clamping plates.

As shown in fig. 1, in this embodiment, the food holding device 3 further includes a bottom plate and a spring, wherein two ends of the bottom plate are respectively provided with a side plate extending upward perpendicular to the bottom plate, one end of the spring respectively abuts against the side plate, and the other end of the spring respectively abuts against the first holding member 31 and the second holding member 32.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
