DETAILED DESCRIPTION
[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.
[0021] like Figure 1-2 As shown, a selective fishing ground cage includes a main cage body 1, a channel 2 is formed in the main cage body 1 along the length direction, a plurality of entrances 3 are arranged on the side of the channel 2 corresponding to the main cage body 1, a connecting port 4 is formed on the main cage body 1 and a deformable supporting frame 5 is provided at the connecting port 4.
[0022] Preferably, it also includes a secondary cage body 6, a screening chamber 7 is formed in the secondary cage body 6, sieve holes 8 are arranged on the surface of the secondary cage body 6, a mounting opening 9 is formed on the secondary cage body 6 and a sleeve frame 10 is provided at the mounting opening 9, the sleeve frame 10 is smaller than the support frame 5, and the sleeve frame 10 is used for the support frame 5 to pass through and sleeve the main cage body 1, so that the screening chamber 7 and the channel 2 are connected to each other.
[0023] When in use, since the support frame 5 is deformable, the shape of the support frame 5 can be adjusted by the deformation of the support frame 5, so that the support frame 5 can be connected through the sleeve frame 10 to complete the connection between the main cage body 1 and the auxiliary cage body 6, and the ground cage is further placed in the field, so that the crayfish can enter the channel 2 along the entrance 3. Since the screening chamber 7 is connected to the channel 2, the crayfish can enter the screening chamber 7 along the channel 2. At this time, the smaller-sized crayfish can escape from the screening chamber 7 through the sieve hole 8, while the larger-sized crayfish are retained in the screening chamber 7 to complete the automatic screening of the crayfish size.
[0024] Therefore, when the crayfish are collected later, the main cage body 1 can be pulled so that all the crayfish in the main cage body 1 fall into the screening chamber 7. Since the support frame 5 passes through the sleeve frame 10 to complete the sleeve connection, the connection stability between the two can be guaranteed, that is, the sleeve frame 10 is difficult to fall off from the main cage body 1, thereby ensuring the connection stability when dumping.
[0025] In addition, a plurality of connection ports 4 can be provided according to the needs of crayfish screening to connect the auxiliary cage bodies 6 with different sieve holes 8 apertures, so as to complete the screening effect of a plurality of crayfish of different specifications at one time.
[0026] In another embodiment, a plurality of mesh surfaces may be provided along the length direction of the auxiliary cage body 6, and different mesh surfaces may have different apertures, so as to achieve the effect of screening crayfish of multiple specifications at one time.
[0027] Preferably, the main cage body 1 and the auxiliary cage body 6 both include a cylindrical mesh 11 and a plurality of inner support frames 12 . The plurality of inner support frames 12 are located inside the mesh 11 and arranged along the length direction to prop up the mesh 11 .
[0028] The mesh 11 is supported by a plurality of inner support frames 12, so that the channel 2 and the screening cavity 7 can be prevented from collapsing, thereby ensuring the supporting effect of the inner space.
[0029] Preferably, a limiting shrinkage section 13 is formed between the sleeve frame 10 and the inner support frame 12 , and the cross-sectional area of the limiting shrinkage section 13 decreases from an end close to the main cage body 1 to an end away from the main cage body 1 .
[0030] The setting of the constriction section 13 can make the crayfish at this position feel crowded and escape faster, thereby reducing the number of crayfish of smaller sizes entering the subsequent area.
[0031] Preferably, the support frame 5 is arranged at the end corresponding to the main cage body 1, and the main cage body 1 forms multiple fishing sections 14 through several parts. The sides of the multiple fishing sections 14 are all provided with entrances 3, and expulsion ports 15 are formed between adjacent fishing sections 14. The expulsion ports 15 are trumpet-shaped and extend and narrow toward the support frame 5.
[0032] The trumpet-shaped expelling port 15 can guide the movement of crayfish, thereby preventing the crayfish from moving back. At the same time, the arrangement of multiple fishing sections 14 and the inlet 3 can improve the fishing efficiency.
[0033] More specifically, a connecting rope is provided on the mesh 11, and the connecting rope connects the inlet 3 and the expulsion port 15 to keep them in a propped-up state.
[0034] Preferably, the inlet 3 is trumpet-shaped and narrows toward the inside of the main cage body 1 , and adjacent inlets 3 are staggered and arranged on both sides of the main cage body 1 .
[0035] The staggered arrangement can ensure the capture efficiency of crayfish on both sides, while making the overall structure more reasonable to increase the internal space.
[0036] Preferably, the inner support frame 12 includes a circle and a rectangle, and in other embodiments, may also include other regular or irregular shapes.
[0037] Circles and rectangles can reduce processing difficulty.
[0038] Preferably, it further comprises a connecting buckle 16 in an annular shape, on which a notch 17 is provided, and the supporting frame 5 and the sleeve frame 10 are respectively connected via the notch 17 .
[0039] By setting the connection port 4, the sleeve frame 10 and the support frame 5 can be connected through the notch 17 after the sleeve frame 10 is sleeved, so as to limit the two, thereby preventing the sleeve frame 10 from falling off during the tipping process, so as to improve the connection strength between the two.
[0040] Preferably, the support frame 5 and the sleeve frame 10 are both circular.
[0041] The circular shape can facilitate the deformation of the support frame 5 to pass through the sleeve frame 10, and can also reduce the contact surface with the ground to expand the escape area.
[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
