[0027] The effect achieved by the entire embodiment 1 is that when it is necessary to catch crab seedlings, the four universal wheels 121 fixedly installed at the bottom of the bottom plate 101 can make the device convenient to move between the breeding ponds, reducing the trouble of manual handling. When the device moves to the fishing area, the first motor 105 is first started, the first motor 105 drives the first threaded rod 104 to rotate, the first threaded rod 104 drives the sliding frame 103 to move back and forth, and the two fixed rods 107 increase the stability of the movement of the sliding frame 103. If the fishing distance is still not enough, the third motor 116 is started at this time, the third motor 116 drives the second threaded rod 117 to rotate, and the rotation of the second threaded rod 117 drives the moving block 118 to move back and forth, further driving the extension The contraction column 119 moves forward and backward, thereby extending or shortening the fishing range.

By arranging two counterweights 120 on the top of the bottom plate 101, the overall weight distribution of the device can be balanced to prevent the problem of the device being top-heavy and having reduced stability due to the fishing range being too long.

[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the fishing mechanism 2 includes a fishing box 201, and a group of crab inlets 202 are opened on one side of the outer wall of the fishing box 201, a first screening plate 203 is fixedly installed on the inner wall of the fishing box 201, and a plurality of first screening holes 204 are opened on the top of the first screening plate 203, a second screening plate 205 is fixedly installed on the inner wall of the fishing box 201, and a plurality of second screening holes 206 are opened on the top of the second screening plate 205, two gravity blocks 207 are fixedly connected to the bottom of the fishing box 201, and the outer wall of the steel rope 113 is fixedly connected to the outer wall of the fishing box 201.

[0029] The effect achieved by the entire embodiment 2 is that the two gravity blocks 207 fixedly installed at the bottom of the fishing box 201 can make the fishing box 201 sink steadily into the breeding pond, thereby ensuring the effectiveness and accuracy of fishing. When the fishing box 201 reaches the predetermined depth, the crab seedlings enter the fishing box 201 from a group of crab inlets 202. During the movement of the crab seedlings, the first screening plate 203 and the second screening plate 205 play a key screening role. The top of the first screening plate 203 is provided with multiple groups of first screening holes 204. These screening holes allow normal-sized and smaller crab seedlings to pass through, while large crab seedlings will be blocked. After the first round of screening, Smaller crab seedlings will enter the second screening plate 205. The top of the second screening plate 205 also has multiple groups of second screening holes 206. These screening holes further distinguish the size of the crab seedlings. Through the precise screening of the first screening holes 204 and the second screening holes 206, the smaller crab seedlings will smoothly enter the bottom of the inner wall of the fishing box 201, while the large crab seedlings will be blocked at the top, and the crab seedlings of ordinary size will remain in the middle position of the fishing box 201. This double screening mechanism not only improves the efficiency of fishing, but also ensures that farmers can accurately capture crab seedlings of the required size, while avoiding the accumulation of large and small crab seedlings, causing damage to the young crab seedlings.

[0030] Working principle: When catching crab seedlings, first move the device to the fishing area through the four universal wheels 121, and then start the first motor 105. The output end of the first motor 105 drives the first threaded rod 104 to rotate, and the rotational movement of the first threaded rod 104 then drives the sliding frame 103 to move back and forth, ensuring the stability of the fishing action. If the fishing distance needs to be further extended, the third motor 116 will be started, which drives the second threaded rod 117 to rotate, thereby driving the moving block 118 to move back and forth, and further drives the telescopic column 119 to move back and forth, greatly expanding the fishing range. At the same time, according to the demand for fishing depth, the second motor 110 starts working, and the output end of the second motor 110 drives the winding roller 111 to rotate. Under the action of the first guide wheel 115 and the second guide wheel 114, the steel rope 113 can be more stably and accurately retracted and released, thereby accurately controlling the depth of the fishing box 201 in the breeding pond, and the two gravity blocks 207 can So that the fishing box 201 can sink smoothly into the water pool. When the fishing box 201 reaches a predetermined depth, the crab seedlings enter the fishing box 201 from a group of crab inlets 202. During the movement of the crab seedlings, the first screening plate 203 plays a role of preliminary screening. The multiple groups of first screening holes 204 opened on the top allow normal-sized and smaller crab seedlings to pass through, while large crab seedlings are blocked. After the first screening, normal-sized and smaller crab seedlings can enter the second screening plate 205. The top of the second screening plate 205 also has multiple groups of second screening holes 206. The multiple groups of second screening holes 206 further distinguish the size of the crab seedlings. Through the precise screening of the first screening holes 204 and the second screening holes 206, the smaller crab seedlings can smoothly enter the bottom of the fishing box 201, the normal-sized crab seedlings will stay in the middle of the fishing box 201, and the large crab seedlings will be blocked at the top. This double screening mechanism not only improves the efficiency of fishing, but also ensures that the farmers can accurately capture the crab seedlings of the required size.
