Description

Technical Field

[0001] The invention belongs to the technical field of crayfish catching, and in particular relates to a light and simplified crayfish catching device. Background Art

[0002] At present, the standardized breeding of crayfish has gradually become large-scale, and the breeding side pays more attention to pond construction, water quality control, scientific feeding and other links. At the same time, in terms of fishing, different breeding conditions and breeding conditions will correspond to different fishing methods. Common fishing methods include ground trap fishing, shrimp cage fishing, scoop net fishing, etc. However, the above fishing methods currently have problems such as low fishing efficiency, low degree of fishing standardization, and long fishing time in large cases. With the development of crayfish breeding technology and scale, crayfish breeding is moving towards standardization, intelligence, scale and so on.

[0003] In the field of modern aquaculture, in order to effectively improve the quality of lobster farming and achieve refined and scientific farming management, the design and application of standardized breeding ponds have become key measures. Usually, such standardized breeding ponds will be carefully built in strict accordance with a series of professional standards and specifications, aiming to create an extremely suitable growth environment for lobsters and fully meet their various needs during growth and development. In terms of the shape of the breeding pond, it is generally designed as a regular rectangle. Such a design is not only convenient for the planning and management of the breeding area, but also more convenient in subsequent breeding operations and equipment installation. The size of the breeding pond will be flexibly determined according to the specific breeding scale. Whether it is small-scale family farming or large-scale commercial farming, efficient farming can be achieved by rationally planning the area of ​​the breeding pond.

[0004] When fishing lobsters in this standardized lobster breeding pond, the traditional fishing method has many disadvantages. At present, the common method is to manually place a large number of ground traps for fishing. This fishing method has exposed many problems in the actual operation process, resulting in extremely low fishing efficiency.

[0005] First of all, just the two steps of placing and collecting ground cages require a lot of time and manpower. Since the area of ​​the breeding pond is often large, in order to cover as much area as possible to increase the catch, a large number of ground cages need to be placed. When the ground cages are placed manually, the staff need to carry the ground cages one by one to various places in the breeding pond for placement. This process is not only labor-intensive but also slow. Similarly, when collecting the ground cages, the staff also need to fish them out of the water one by one. Faced with so many ground cages, this is undoubtedly a time-consuming and laborious task.

[0006] Secondly, the random placement of ground cages can easily lead to uneven distribution of ground cages. Due to the lack of scientific placement planning, the ground cages may be too dense in some areas of the breeding pond, while they are sparsely distributed in other areas. This results in a large number of lobsters in some areas being caught during the fishing process, while lobsters in other areas may not be effectively caught due to insufficient ground cages, thus affecting the overall fishing effect.

[0007] Furthermore, after collecting the cages, it is also difficult to take out the lobsters inside. Since the cages are generally long, usually several meters or even more than ten meters long, it is difficult to lift them out manually. The staff often need to lift the cages section by section and gather them together before taking out the lobsters one by one. This process is not only cumbersome to operate, but also easily causes the lobsters to be frightened or injured during the removal process, which in turn affects the quality of the lobsters.

[0008] Finally, during the stage of casting the ground cage, there is a problem that cannot be ignored during the manual casting process, that is, it is easy to cast the entrance of the ground cage to the upper and lower sides. Once this happens, it will seriously affect the smooth entry of the crayfish into the ground cage. Because crayfish usually move at the bottom of the water or in the middle and lower layers of the water body in their natural state, when the entrance of the ground cage is facing up or down, it is difficult for the crayfish to find the entrance and enter smoothly, which greatly reduces the fishing effect of the ground cage.

[0009] In summary, the traditional method of catching fish by randomly placing ground traps manually can no longer meet the urgent needs of the modern lobster farming industry to reduce farming costs and improve fishing efficiency. Based on this, in order to effectively solve these problems and achieve the sustainable development of the lobster farming industry, the present invention provides a simplified catching device for crayfish.

[0031] The following is combined with Figure 1-6 This application is further described in detail.

[0032] Please refer to Figure 1 and Figure 2 A simplified crayfish catching device comprises a telescopic cylinder 1 which is vertically fixed at four corners of a standardized lobster breeding pond; a limit top frame 2 is fixedly arranged at the telescopic ends of the four telescopic cylinders 1; a plurality of lifting units 3 are slidably arranged on the limit top frame 2, and adjacent lifting units 3 are connected by a shear-type telescopic structure 4; an energy storage solar photovoltaic panel 5 is also laid on the upper end of the limit top frame 2.

[0033] Before work, the telescopic cylinder 1 is first used to synchronously lift the cage to a suitable height, and a suitable number of hoisting units 3 are installed according to the breeding density of the crayfish breeding pond and the size of the breeding pond. Then, the cage is manually fixed on the hoisting unit 3, and moved to a suitable position through the shear-type telescopic structure 4, cooperating with the synchronous contraction of multiple telescopic cylinders 1; finally, the cage is placed in a suitable water area; after the cage has been left still for a certain period of time, it is automatically lifted up, and after being lifted up, the cage is moved to the side position again through the shear-type telescopic structure 4, and the lobsters inside can be taken out manually. When it is used again in the future, it only needs to put a proper amount of bait into the cage for fishing again; the energy storage solar photovoltaic panel 5 provides power for the present invention, and the use cost of the present invention is effectively reduced by utilizing solar energy.

[0034] See also Figure 3 The limit top frame 2 is a frame structure composed of a length guide rod 21 and a width guide rod 22 which are staggered and plugged in sequence through corner sleeves; the two length guide rods 21 are provided with limit grooves 211 extending along their length direction on opposite sides, and the two length guide rods 21 are also provided with guide grooves 212 located above the limit grooves 211 and penetrating the length guide rods 21 along their length direction.

[0035] See also Figure 3 The hoisting unit 3 includes a wire control assembly 31 slidably disposed in the guide groove 212 for reeling and hoisting the ground cage, and an auxiliary assembly 32 slidably disposed in the limiting groove 211 and cooperating with the wire control assembly 31 to assist in limiting the lowered ground cage.

[0036] See also Figure 4 and Figure 5 The control line assembly 31 comprises a rectangular limit frame 311 slidably arranged inside the guide groove 212, and an outer control sleeve rod 312 is detachably arranged inside the rectangular limit frame 311. The outer wall of the outer control sleeve rod 312 is evenly provided with through grooves communicating with the interior thereof, and a limit block 313 is arranged inside the through groove by a spring, and the limit block 313 is connected to the side wall of the through groove by a spring, and the limit block 313 can move along the radial direction of the outer control sleeve rod 312; the outer control sleeve rod 31 2 is also provided with a limit control rod 314 for damping rotation, and the outer wall of the limit control rod 314 is evenly provided with arc-shaped protrusions that cooperate with the limit block 313; the outer wall of the outer control sleeve rod 312 is evenly sleeved with a line control module 315, and the line control module 315 is lifted up by rotating the arc-shaped protrusion of the limit control rod 314 and cooperating with the limit block 313 to position the line control module 315; the line control module 315 cooperates with the side wall of the rectangular limit frame 311 in a sliding manner.

[0037] See also Figure 5The line control module 315 includes a fixing cover 3151 sleeved on the outer wall of the outer control sleeve rod 312; a wire hole 3152 is opened on the outer wall of the fixing cover 3151; a rectangular block 3153 is provided on the outer wall of the fixing cover 3151 for sliding cooperation with the side wall of the rectangular limit frame 311; a wire harness I-shaped wheel 3154 is provided on the inner wall of the fixing cover 3151 in a rotating manner, and the wire harness I-shaped wheel 3154 is driven by an electric slider arranged inside, a wire harness 3155 is wound on the wire harness I-shaped wheel 3154, one end of the wire harness 3155 passes through the wire hole 3152 opened on the outer wall of the fixing cover 3151 and is located on the outer side of the rectangular limit frame 311; when in use, the end of the wire harness 3155 is connected to one end of the ground cage.

[0038] When the breeding density of the standardized breeding pond is relatively high, the number of ground cages can be appropriately increased. Specifically, a suitable number of line control modules 315 can be installed. When adjusting the position of the line control module 315, it slides along the outer wall of the outer control sleeve 312. After the position adjustment is completed, the limit control rod 314 is rotated to push the limit block 313 out and fix it tightly against the inner circle of the fixing cover 3151 through the arc-shaped protrusion on its surface; the set line control component 31 is convenient for increasing or decreasing the number according to the lobster breeding density or the size of the standardized breeding pond.

[0039] When collecting the ground cage, the electric slider drives the wire harness I-wheel 3154 to rotate to complete the winding of the wire harness 3155, thereby completing the lifting of the ground cage; since the mechanized method of lifting the ground cage does not require the physical strength of the staff, the lifted ground cage is in a vertical state, and the crayfish inside the ground cage will gather at the lower end of the ground cage. At this time, the staff only needs to open the lower end of the ground cage, which greatly improves the efficiency of catching crayfish and reduces the cost of breeding crayfish.

[0040] See also Figure 3 The auxiliary component 32 includes a guide frame 321 slidably arranged inside the limiting groove 211, and a plurality of auxiliary modules 322 corresponding to the positions of the line control modules 315 are clamped on the guide frame 321. The auxiliary modules 322 are slidably matched with the guide frame 321, and one end of the auxiliary module 322 is connected to the fixing cover 3151.

[0041] See also Figure 6 The auxiliary module 322 includes a positioning pin 3221 with a rubber sleeve rotating on the outer wall; the positioning pin 3221 is slidably set inside the guide frame 321, and the upper end of the positioning pin 3221 is connected to a fixing plate 3222 with a threaded hole inside, and the fixing plate 3222 is internally threadedly connected to a connecting rod 3223, and the other end of the connecting rod 3223 is threadedly connected to a connecting block 3224, and the connecting block 3224 is fixedly connected to the side wall of the fixing cover 3151.

The air outlet of the air pump 3226 is connected to an air mold plug 3227, and the air mold plug 3227 is arranged on the side wall of the lower end of the telescopic suspension rod 3225; the length of the air mold plug 3227 when inflated and opened is greater than the diameter length of the mesh of the ground cage.

[0043] According to the length of the ground cage to be released, the connecting rod 3223 is screwed to adjust the distance between the fixing plate 3222 and the connecting block 3224, so as to facilitate the lower end of the telescopic suspension rod 3225 to restrain and fix the ground cage later. Specifically, when the ground cage is filled with an appropriate amount of bait and needs to be released, the auxiliary module 322 can fix the lower end of the ground cage. When fixing the ground cage, the ground cage is pulled to a horizontal level to ensure that the entrance position of the ground cage will not be located on the upper and lower sides of the ground cage, and then the mesh of the ground cage is hung by the air plug 3227; the shear-type telescopic structure 4 and the telescopic cylinder 1 are used to move multiple ground cages to the appropriate position of the breeding pond. When released, air is sucked in by the air pump 3226 to discharge the gas inside the air plug 3227. At this time, the air plug 3227 releases the fixation on the mesh position of the ground cage after the gas is discharged, and the ground cage will be released into the breeding pond to trap crayfish.

[0044] See also Figure 2 and Figure 3 The shear-type telescopic structure 4 at any end of the length direction of the limiting top frame 2 is hinged with the width guide rod 22; the purpose of setting the shear-type telescopic structure 4 is to automatically adjust the position of the ground cage below. At the same time, when the ground cage is collected, it is also convenient to concentrate the ground cages in the same area, which is convenient for collecting the crayfish inside.
