Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1, to facilitate sorting of the fish catch. The utility model provides a suspended type fish catch sorting device which comprises a temporary rearing pond 1, a sorting assembly and a fish chute 2, wherein the sorting assembly is arranged on the water surface in the temporary rearing pond 1 in a floating mode and used for screening fish catches, the fish chute 2 is arranged at the top of the temporary rearing pond 1 and used for conveying the fish catches into the temporary rearing pond 1, an opening is formed in the center of the top of the sorting assembly, the output end of the fish chute 2 is positioned right above the opening of the top of the sorting assembly, the sorting assembly comprises a plurality of layers of screens which are arranged in a sleeved mode and used for sorting the fish catches, and the calibers of the screens of all layers in the sorting assembly are decreased from inside to outside.

The fish catch flows out along with water from the bottom outlet of the fish chute 2, falls into the middle screen cloth of one layer, the inner screen cloth sorts the fish catch first, the aperture of the inner screen cloth is the largest, the large-size fish catch is left in the inner sorting basket, the middle screen cloth sorts out the medium-size fish catch, the small-size fish catch passes through the middle screen cloth, and the fish goods are sorted according to the body types. In the sorting process, the continuous water delivery of the fish chute 2 into the temporary rearing pond 1 is required to be ensured, the directionality of water flow is ensured while oxygenation is carried out, and small fish gains are prevented from flowing back into the sorting basket of the middle layer or the inner layer. After sorting is finished, weighing and measuring the fishery gains can be performed.

As shown in fig. 1, to ensure that the top of the sorting basket floats on the water surface. The sorting assembly comprises a first sorting basket 3, a second sorting basket 4 and a third sorting basket 5 which are sleeved and arranged, wherein the first sorting basket 3 is located at the innermost side, the third sorting basket 5 is located at the innermost side, the tops of the first sorting basket 3, the second sorting basket 4 and the third sorting basket 5 are respectively provided with a first buoyancy ring 31, a second buoyancy ring 41 and a third buoyancy ring 51 which are internally inflated, the bottoms of the first buoyancy ring 31, the second buoyancy ring 41 and the third buoyancy ring 51 are respectively and coaxially connected with a first screen mesh 32, a second screen mesh 42 and a third screen mesh 52, and the bottoms of the first screen mesh 32, the second screen mesh 42 and the third screen mesh 52 are respectively connected with a semi-elliptic first bottom basket 33, a second bottom basket 43 and a third bottom basket 53.

The first buoyancy ring 31, the second buoyancy ring 41 and the third buoyancy ring 51 are swimming rings or riding inner tubes, the first screen 32, the second screen 42 and the third screen 52 are hexagonal fish bag mesh fabrics, and the first bottom basket 33, the second bottom basket 43 and the third bottom basket 53 are existing metal bottom fences; the connection mode of the screen mesh and the buoyancy ring is that the top end of the screen mesh is wound on the buoyancy ring, and then the top end of the screen mesh is sewed with the top of the screen mesh, namely the buoyancy ring is sewed on the screen mesh; the first bottom basket 33, the second bottom basket 43 and the third bottom basket 53 adopt the existing metal material of the fish screen, so that the fish screen can be used for balancing the sorting basket, ensuring that the main bodies of the first screen 32, the second screen 42 and the third screen 52 in water are in a vertical state, and can be used for sorting the fish and the obtained objects. The length of the first screen 32, the second screen 42 and the third screen 52 may be selected according to the number and volume of fish traps required to be intercepted by the first sorting basket 3, the second sorting basket 4 and the third sorting basket 5, ensuring that there is sufficient living space for the fish traps falling within each sorting basket.

In addition, set up the ribbon at the top of each letter sorting basket, after the fish catch letter sorting finishes, with first letter sorting basket 3 and second letter sorting basket 4 respectively from the third letter sorting basket 5 in put forward, place alone to seal each letter sorting basket through the ribbon, place the fish catch thing and jump out from in the letter sorting basket.

As shown in fig. 1, to avoid deformation of the first screen 32 due to large-scale fish play, the fish in the second sorting basket 4 is squeezed. The first screen 32 is a vertical rod directly connected to the first bottom basket 33.

Because each layer of sorting basket adopts the form of suit, lead to the limited length of first sorting basket 3, big size's fishing catch thing power is great, if first screen cloth 32 of string bag cloth preparation, can cause the deformation of first screen cloth 32, extrudees the midbody type fish in the second screen cloth 42. When the first screen 32 formed by the rod piece is installed, an annular structure is arranged at the top end of the first screen 32, an opening is formed in the inner side of the annular structure, the first buoyancy ring 31 which is not inflated is installed in the annular structure from the opening, and then the first buoyancy ring 31 is inflated, so that the connection between the first buoyancy ring 31 and the first screen 32 can be realized.

As shown in fig. 1, to avoid large fish catch jumping out of the first sorting basket 3. The top of the first screen 32 is provided with an inwardly converging neck section. Because the first sorting basket 3 is located in the middle of the sorting assembly, the large fish catch is all located near the water surface, and if the large fish catch has fierce fish, the large fish catch can jump out from the inner side of the first buoyancy ring 31, so that on the basis of the first screen 32 provided with the rod assembly, the necking section is arranged at the top of the first screen 32, and the large fish catch is prevented from jumping out from the first sorting basket 3.

As shown in fig. 1, to effect the securing of the sorting basket. The third sorting basket 5 is located the outermost side of sorting basket, the top of third sorting basket 5 is provided with go-between 7, the inner wall top of support pond 1 temporarily is provided with the solid fixed ring 6 of spring latch closure structure. In order to avoid sorting basket to be driven by the fishing catch or rivers of its inside and keep away from swift current fish tank 2, set up solid fixed ring 6 at the inner wall of raising pond 1 temporarily, gu fixed ring 6 includes both ends, and one end is fixed section, and one end is the section of rotating, and the one end of rotating the section articulates in the one end of fixed section, and the other end of rotating the end can lock at the other end of fixed section, is connected with the spring that is used for rotating section reset on the hinge between section of rotating and the fixed section, and the spring elasticity direction is towards the inboard of solid fixed ring 6. When taking out the first sorting basket 3, the second sorting basket 4 and the third sorting basket 5 in the temporary rearing pond 1 completely, the connecting ring 7 is separated from the fixed ring 6, and the first sorting basket 3, the second sorting basket 4 and the third sorting basket 5 are pulled manually along the water surface, so that the three sorting baskets can be taken out of the water completely after being not located below the fish chute 2.
