[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a grading fishing net device for fish cultured in a pond, comprising a net cover bracket 1, the side and bottom positions of the net cover bracket 1 are fixedly connected with a fishing outer net 2, fish in the pond can be caught with the help of the net cover bracket 1 and the fishing outer net 2, and a connecting rod 3 is threadedly connected to one side of the top of the net cover bracket 1, and the net cover bracket 1 and the fishing outer net 2 can be conveniently controlled to move as a whole in the pond by holding the connecting rod 3, a fixed upper plate 8 and a fixed lower plate 9 are respectively fixedly connected to the surface at the top position of the net cover bracket 1, and a grading inner net 10 is fixed to the lower surface of the fixed lower plate 9, one end of the grading inner net 10 is fixedly connected to the fishing outer net 2, and the space enclosed by the fishing outer net 2 is divided into large and small by the grading inner net 10, forming a large space on one side. The grading inner net 10 is used to control the grading inner net 10 to be placed horizontally, and then the grading inner net 10 is used to control the grading inner net 10 to shake back and forth. With the help of the grading inner net 10, the smaller fish are quickly screened to the space on the other side, so that the big fish and the small fish are placed in the large space and the small space respectively to complete the grading and differentiation. The top of the grading inner net 10 is slidably penetrated by a closed grating plate 11, which serves to close the top openings of the large space and the small space, and effectively prevents the fish from running out of the opening when the size of the fish is screened. The edge of the closed grating plate 11 is threadedly connected with a bolt 12, and the bolt 12 is also threadedly connected to the grating bracket 1 or the fixed upper plate 8, and the bolt 12 serves to fix the closed grating plate 11 on the grating bracket 1.

[0020] Example 2

[0021] like Figure 1-3As shown, the connecting rod 3 is divided into three sections, namely the front section of the connecting rod 3, the middle section of the connecting rod 3 and the rear section of the connecting rod 3. Each section of the connecting rod 3 is threadedly connected to each other, so that it is convenient to separate or assemble the connecting rod 3 as a whole. A lifting handle 5 is fixedly connected to the surface of the middle section of the connecting rod 3, and a clamping block 6 is fixedly connected to the surface of the top of the net cover bracket 1, and the clamping block 6 is clamped and connected with the middle section of the connecting rod 3. After the fish are graded and distinguished by the grading inner net 10, the assembled connecting rod 3 is separated, and the middle section of the connecting rod 3 is connected to the clamping block 6, so that the net cover bracket 1 and the fishing outer net 2 become similar to a storage and transportation barrel for fish, and the fish can be easily transported by carrying the lifting handle 5. The tail fixing sleeve of the rear section of the rod 3 is provided with an anti-skid sleeve 4, and the anti-skid sleeve 4 has an anti-skid effect. By holding the anti-skid sleeve 4, the stability of the connecting rod 3 after dancing assembly is effectively improved. The anti-skid sleeve 4 is fixedly connected to the two sides of the mesh cover bracket 1 with clamping parts 7, and the clamping parts 7 are engaged and connected with the front section of the connecting rod 3 and the rear section of the connecting rod 3. The clamping parts 7 play the role of storing the front section of the connecting rod 3 and the rear section of the connecting rod 3 on the mesh cover bracket 1, which is convenient for placing other free parts after the connecting rod 3 is separated as a whole. An anti-skid protrusion 13 is fixedly connected to the outer surface of the torsional end of the bolt 12. The friction force of the torsional end of the bolt 12 is increased by setting the anti-skid protrusion 13, making it more convenient for the bolt 12 to be manually twisted.

[0022] Working principle:

[0023] like Figure 1-3As shown, when the utility model is in use, the user first ensures that the closed net cover plate 11 is in a semi-open state on the net cover bracket 1, and fixes one end of the closed net cover plate 11 to the fixed upper plate 8 by means of bolts 12, so that the closed net cover plate 11 closes the opening of the small space on one side of the fishing outer net 2, and then holds the anti-slip sleeve 4 of the assembled connecting rod 3 to control the connecting rod 3 to dance, thereby driving the net cover bracket 1 connected to its front end to move as a whole into the pond to catch fish, and after the fish are caught in the large space on one side of the fishing outer net 2, the net cover bracket 1 is taken out of the pond, and then the bolts 12 are twisted and rotated at the anti-slip protrusions 13 to disassemble, so that the closed net cover plate 11 can be moved again and the opening on one side of the net cover bracket 1 is fully closed, and then the bolts 12 are tightened again. One side of the top of the net cover bracket 1 is connected to the net cover bracket 1 and the closed net cover plate 11 to fix the closed net cover plate 11, and then the front end of the assembled connecting rod 3 is rotated and removed from the net cover bracket 1, and then the net cover bracket 1 is turned over to place the grading inner net 10 horizontally, and then the net cover bracket 1 is controlled to shake back and forth with both hands. With the help of the grading inner net 10, smaller fish are quickly screened to the space on the other side, so that large fish and small fish are respectively placed in the large space and small space in the fishing outer net 2 to complete the grading and separation, and then the assembled connecting rod 3 is rotated and disassembled into three sections, the front section and the rear section of the connecting rod 3 are clamped at the clamping piece 7, and the middle section of the connecting rod 3 is clamped at the clamping block 6, and then the hand is pulled at the lifting handle 5 to facilitate the transfer and transportation of the fish.
