Description
Technical Field
The utility model belongs to the technical field of the instrument is catched to the aquatic products, concretely relates to ground cage net that alternative was catched.
Background
The ground cage net is a fixed fishing gear for catching aquatic organisms, and is widely used for catching natural aquatic products in sea and fresh water and cultured aquatic animals. In fresh water pond culture, river crabs and freshwater shrimps are cultured in a mixed mode, which is an ecological and efficient culture mode, and the ground cage net is the most main fishing tool of the culture mode. In the shrimp and crab mixed culture pond, the freshwater shrimps and the river crabs are not harvested synchronously, the freshwater shrimps can be harvested and left small in advance (in the middle ten days of 9 months) according to the growth conditions in the culture process of the next half year, and the river crabs are collectively harvested and put on the market in 11-12 months. When the freshwater shrimps are caught by the common cages, the river crabs can enter the cages, so that the activities of the river crabs are influenced, and the casualties and the losses of the freshwater shrimps are increased. In order to overcome the problem, when some farmers catch shrimps, the openings of the cage tips of the ground cages are opened and lifted 15-20 cm away from the water surface, so that river crabs entering the cages can climb out of the cage tips, and freshwater shrimps cannot leave water and stay in the cage tips. This method is not ideal because river crabs entering the cages often do not want to come out of the cages, and the freshwater shrimps just in the cage tips are taken as food, so that the freshwater shrimps caught in the cages are lost.
Disclosure of Invention
In order to solve the problem of fishing the common ground cages in shrimp and crab cultivation, the utility model discloses reequip the common ground cage net, let it become the ground cage net that an alternative was fished, can only let the freshwater shrimp freely enter the cage, and the unable entering of river crab has solved above-mentioned problem that relates to completely.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a ground cage net that alternative was catched, ground cage net mid portion sets up ground cage net main body frame, ground cage net both sides set up supporting framework, set up the etting on the ground cage net main body frame, set up the cage on the supporting framework and net the bag slightly, the etting both ends are connected with the cage net bag slightly of both sides, the etting with ground cage net main body frame forms a cavity passageway, wherein: the net cover on the side surface of the ground cage net is provided with an inverted beard inlet through which shrimps and crabs can enter the cage, a plug-in net vertical to the inlet surface of the inverted beard inlet is arranged in the middle of the inverted beard inlet, and the inverted beard inlet is divided into two inlets through the plug-in net, wherein the inlets can only allow freshwater shrimps to freely enter.
Further, the main frame of the ground cage net is a rectangular frame.
Further, the support framework is a circular support framework.
Further, the inverted beard inlet is a funnel wing net which gradually shrinks towards the inner cavity channel of the ground cage net.
Furthermore, the net opening of the funnel wing net is rectangular.
Further, the shape of the insert net is matched with that of the inverted beard inlet, and the inserting edge of the insert net is flush with the inlet face of the inverted beard inlet.
Furthermore, the number of the inverted beard inlets is at least one, and each inverted beard inlet is provided with a plug-in net.
Further, the plug-in net is a trapezoidal plug-in net.
Has the advantages that: the utility model discloses a reequip ordinary ground cage net, need the import department at ordinary ground cage net near falling certainly to install a trapezoidal plug-in components net that can load and unload additional, let it become the ground cage net that an alternative was catched, can only let the freshwater shrimp freely advance the cage, and the river crab can't get into.

FIG. 3 is a side view of the ground cage of the present invention;
wherein: 1 is a plug-in net, 2 is a netting, 3 is a clip-shaped needle-shaped steel wire buckle, 4 is an inverted beard inlet, 5 is a cage-tip net bag, 6 is a main body frame, 7 is a supporting framework, and 8 is a funnel wing net.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model provides a ground cage net that alternative was catched, ground cage net mid portion sets up ground cage net main body frame 6, ground cage net both sides set up supporting framework 7, set up etting 2 on the ground cage net main body frame 6, set up cage gauze bag 5 slightly on the supporting framework 7, the 2 both ends of etting are connected with cage gauze bag 5 slightly of both sides, etting 2 with ground cage net main body frame 6 forms a cavity passageway, wherein: the net cover 2 on the side face of the ground cage net is provided with an inverted beard inlet 4 for shrimps and crabs to enter the cage, the middle position of the inverted beard inlet 4 is provided with a plug-in net 1 vertical to the inlet face of the inverted beard inlet 4, and the plug-in net 1 divides the inverted beard inlet 4 into two inlets only allowing freshwater shrimps to freely enter.
As shown in fig. 2, the oblique sides of the plug-in net 1 are provided with a clip-shaped needle-shaped steel wire buckle 3, and the clip-shaped needle-shaped steel wire buckle 3 is detachably connected with the inverted beard inlet 4.
If the ground cage inlet is large, the net wire can be properly narrowed down, so that 2 separated openings are small enough after the plug-in net is installed, and only freshwater shrimps can freely pass through the openings, but river crabs cannot pass through the openings.
Plug-in nets can be installed at each inlet of the whole ground cage, and the ground cage can be specially used for catching freshwater shrimps. When a large amount of river crabs need to be caught in the later period, the plug-in net can be detached and restored into a common ground cage for catching the river crabs.
Example 1
20 m large-size folded net-connected ground cage with 45 joints/30 inlets, net frame 33 x 45 cm, net side length 0.8 cm, net bone diameter 4.0 mm, and double-head inverted shrimp (crab). Install trapezoidal plug-in components net (mesh length of side 0.5 centimetre) that 6 centimetres are high additional, two both sides hypotenuses respectively evenly use 5 to return the shape needle-like steel wire knot and fix in the middle of the wing net on ground cage side import funnel, during operation plug-in components net is in the state of expanding completely, trapezoidal minor face and import parallel and level, and 2 imports that are divided into by the plug-in components net only can let the freshwater shrimp freely pass through. Plug-in nets are additionally arranged on all 30 inlets. The modified ground cage is used for trapping shrimps by a conventional method, so that 100% of freshwater shrimps can be trapped without influencing the life of river crabs. And when the river crabs need to be caught in the later period, the trapezoidal plug-in net is detached, and the river crabs are normally caught.
