Examples

Referring to fig. 1-6, the embodiment discloses an automatic fishing device for industrial fish farming, which comprises a culture pond 1, a first rotor wing 31, a second rotor wing 32 and a bottom screen plate 6, wherein a fish outlet 11 is formed in the side edge of the culture pond 1, a screw-nut transmission device 5 is arranged in the center of the culture pond 1, a motor 42 is connected with a screw rod 52 through a coupler 43, the motor 42 can drive the screw rod 52 to rotate, and the screw rod 52 rotates to drive a screw rod nut 53, a linear bearing 54 and the bottom screen plate 6 to ascend or descend together. The bottom otter board 5 is hugged closely in 1 bottoms of the breed pond in the normal condition, and screw nut transmission device 5 carries on bottom otter board 6 and upwards promotes, compresses fish and breeds the region, and when bottom otter board 6 risees to contact first rotor 31 and second rotor 32, bottom otter board 6 stops rising, and first rotor 31 and second rotor 32 begin rotatory, further compress fish and breeds the region, along with the fish breeds the region constantly diminishes, and fish is forced to swim out from fish outlet 11 mouth to realize the automatic fishing of harvest period. The device is simple and quick to operate, and can realize efficient automatic fishing of industrial fish culture.

The support frame 2 includes first support column 21, bracing piece 22, second support column 23, and the optional 304 stainless steel of support frame 2 is installed fixedly on ground through the inflation screw to first support column 21 and second support column 23, and bracing piece 22 passes through screw nut to be fixed on first support column 21 and second support column 23, and support frame 2 plays the supporting role of whole automatic fishing device.

The first rotor 31 is fixed to the first rolling bearing by a first fixing block 33 and a second fixing block 35, the second rotor 32 is fixed to the first rolling bearing by a third fixing block 34 and a fourth fixing block 36, and the first rotor 31 and the second rotor 32 are rotatable around the motor case 4.

The filter screen 71, the third rolling bearing 72, the guide rail fixed block 73 are arranged in the center of the bottom of the culture pond 1, the filter screen 71 can filter impurities generated in fish culture, small fishes can be prevented from entering the water circulation system along with water flow, and the third rolling bearing 72 and the guide rail fixed block 73 are fixed on the filter screen 71. To increase the stability of the screw-nut transmission 5, it is also possible to fix the third rolling bearing 72 and the guide rail fixing block 73 to the bottom of the tank 1, which requires the addition of holes of corresponding dimensions in the filter screen.

When the fish is cultivated in a normal state, the bottom screen plate 6 is tightly attached to the bottom of the cultivation pool 1, the rotor wing 31 and the rotor wing 32 are fixed on the first rolling bearing of the motor case 4 and do not enter water, so that the fish can be guaranteed not to normally swim, and meanwhile, the requirements of feeding, water quality circulation and the like in the normal state cultivation are not influenced.

When the fishes are harvested, the fishes need to swim out of the fish outlet 11, and the water surface is lowered after the fishes swim out, so that water is continuously added into the culture pond 1 in the whole fish outlet process, the water surface is always parallel to the bottom surface of the fish outlet 11 or slightly higher than the bottom surface of the fish outlet 11, and the water adding process can be realized through a water circulation system of industrial fish culture.
