By 2019, the cultivation area of the national rice and shrimps reaches 1400 million mu, the comprehensive cultivation of the rice and shrimps is taken as important measures for guaranteeing the national grain safety, promoting the green development of the aquaculture industry, implementing the village revitalization strategy, popularizing the comprehensive cultivation of the rice and the fishery, improving the comprehensive benefits of the rice field, realizing grain stabilization, fish promotion, quality improvement and efficiency improvement, developing high-quality, characteristic, green and ecological aquatic products, accelerating the green development of the aquaculture industry, promoting the transformation and upgrading of the industry, optimizing the resource allocation, improving the full-factor productivity, enhancing the development vigor and improving the comprehensive benefits of the green cultivation.
The existing lobster fishing tool usually utilizes ships in water to manually collect and catch the lobster cages and then places the lobster cages, so that one person is difficult to operate, time and labor are wasted, the lobster cages are in a strip bag shape, only one end of each lobster cage is opened, and the yield is low in day and night.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect, the utility model aims to provide a semi-manual fishing and many openings shrimp pot device that rational in infrastructure, conveniently catch.
Therefore, the utility model adopts the technical scheme that: a semi-manual fishing and multi-opening shrimp cage device comprises two fixed rods (1) which are correspondingly arranged at two sides of a river, wherein pulleys (2) are arranged on the fixed rods (1) at least at one side; the lobster fishing device is characterized in that pull ropes (3) which bypass the pulleys (2) are arranged on the two fixing rods (1), a lobster cage (4) used for catching lobsters is arranged on the pull ropes (3), and the length of each pull rope (3) meets the following requirements: when the lobster cage (4) sinks into the water to catch lobsters, a catching person on the other side of the pulley (2) can catch the free end of the pull rope (3).
Further, the shrimp cage (4) adopts the following structural form: the whole body is in a square structure form, a plurality of openings (7) for lobsters to enter the shrimp cage (4) are formed in the side face of the shrimp cage (4), and the two ends of the shrimp cage (4) are connected to the pull rope (3).
Furthermore, the width of the shrimp cage (4) is correspondingly arranged with the width of the circular groove.
Furthermore, the shrimp cage (4) is divided into a plurality of independent areas of shrimp cavities (6) through a separation net (5), and openings (7) on the side surfaces of the shrimp cavities (6) are arranged in a grading mode in size and are used for lobsters of different sizes to enter the shrimp cage.
Furthermore, meshes are arranged on the side surface and the top surface of the shrimp cage (4), and the bottom surface of the shrimp cage (4) is in an integral surface structure.
The utility model has the advantages that: the utility model discloses a setting of pulley to length such as stay cord carries out reasonable setting, adds the reasonable setting of shrimp cage structure, makes the utility model discloses a shrimp cage device can fine adaptation lobster catch needs, improves lobster catch efficiency, has fine practicality.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a fixed rod, 2 is a pulley, 3 is a pull rope, 4 is a shrimp cage, 5 is a separation net, 6 is a shrimp cavity, and 7 is an opening.
Detailed Description
A semi-manual fishing and multi-opening shrimp cage device comprises two fixed rods 1 which are correspondingly arranged at two sides of a river, wherein a pulley 2 is arranged on the fixed rod 1 at least at one side; the two fixing rods 1 are provided with pull ropes 3 which go around the pulleys 2, the pull ropes 3 are provided with shrimp cages 4 for catching lobsters, and the length of the pull ropes 3 meets the following requirements: when the shrimp cage 4 sinks into the water to catch lobsters, a catching person on the other side of the pulley 2 can catch the free end of the pull rope 3.
Further, the shrimp cage 4 adopts the following structural form: the whole is in a square structure form, a plurality of openings 7 for lobsters to enter the shrimp cage 4 are formed in the side face of the shrimp cage 4, and two ends of the shrimp cage 4 are connected to the pull rope 3.
Furthermore, the width of the shrimp cage 4 is corresponding to the width of the circular groove.
Furthermore, the shrimp cage 4 is divided into a plurality of independent areas of shrimp cavities 6 through separation nets 5, and openings 7 in the side surfaces of the shrimp cavities 6 are arranged in a grading mode, so that lobsters of different sizes can enter the shrimp cage.
Furthermore, meshes are arranged on the side surface and the top surface of the shrimp cage 4, and the bottom surface of the shrimp cage 4 is in an integral surface structure.
The following is a further explanation of the present invention to better understand the present invention: the utility model adopts the structure that the pulleys 2 are arranged on the fixing rods 1 opposite to the river channel, and the shrimp cages 4 are pulled to the opposite bank through the pull ropes 3 manually at the bank side of the rice field, so that only one person is needed to operate the lobsters for catching, and the labor force and the time are saved by two thirds compared with the traditional catching method; the multi-opening shrimp cage device is suitable for the paddy field shrimp culture circular ditch, adopts length and circular ditch width to be suitable, and horizontal multi-opening shrimp cage 4 blocks crayfish trip (climb) line completely, adds water (drains) in import (export), makes the water slowly flow, and crayfish moves along with rivers, constantly gets into the shrimp cage from many openings 7, catches output and greatly improves.
The utility model discloses there is the difference in the 7 sizes of opening that correspond the setting on each shrimp chamber 6, and this has had preliminary pre-classification to the shrimp that gets into in each shrimp chamber 6 separately in the aspect of the size to a certain extent, has reduced the lobster like this and has catched and accomplish follow-up shrimp and carry out hierarchical work load according to the size, has fine practicality.
Opening 7 prior design become circularly, circular opening back is the arc surface smooth like this, avoid square etc. to cause the shrimp to be getting into some influences that 4 in-process shrimps in the shrimp cage produced because of the existence of hem, further guaranteed the quality of shrimp.
The utility model discloses the existence of separate net 5 has strengthened the mobile degree of shrimp cage 4 and outside air, has further improved the environment of shrimp cage 4, and the structural style of whole face is set to 4 bottom surfaces of shrimp cage, provides favourable environment for the normal motion of lobster in shrimp chamber 6.
