Fishing device for octagonal culture pond

Abstract

The invention discloses a fishing device for an octagonal culture pond. The fishing device for the octagonal culture pond comprises a sliding seat, a fishing box and driving screw rods which are arranged horizontally; the two ends of the sliding seat are respectively in threaded connection with the driving screw rods on two sides; a lifting oil cylinder is arranged at the lower end of the slidingseat; a piston rod of the lifting oil cylinder is ascended and descended vertically and is connected with the fishing box; the fishing box comprises a primary box and secondary boxes; the secondary boxes are symmetrically arranged at the left end and the right end of the primary box; a bearing with a seat is arranged at the upper end of the primary box; the bearing with the seat is connected witha double-headed screw rod; bearing seats are arranged at the two ends of the double-headed screw rod; the bearing seats are arranged in the mounting seats at the upper ends of the secondary boxes; anda servo motor which is used for driving the double-headed screw rod to rotate is arranged on a primary top plate. The invention aims to provide the fishing device for the octagonal culture pond, which can adapt to the octagonal culture pond and realize automatic fishing.

Description

Technical field [0001] The invention relates to the field of aquatic product breeding, in particular to a fishing device used in an octagonal breeding pond. Background technique [0002] There will be dead corners of water flow at the four corners of the quadrilateral farming pond, which is inconvenient for water exchange and sewage discharge. Although the four corners of the quadrilateral farming pond can be rounded to facilitate water exchange and sewage discharge, the square rounded farming pond is not easy to construct; Although circular culture ponds can avoid dead corners of water flow, the land utilization rate is low, while octagonal culture ponds can increase land utilization rate while taking into account water exchange and sewage discharge, and are easy to build. Therefore, breeding farms are often used when aquaculture area is limited. An octagonal aquaculture pond is used; and the inner wall of the octagonal aquaculture pond has corners, so when using conventional au...

[0002] The four corners of the quadrilateral culture pond will have dead corners of water flow, which is inconvenient for water exchange and sewage discharge. Although the four corners of the quadrilateral culture pond can be rounded to facilitate water exchange and sewage discharge, the square round corner culture pond is not easy to construct; Although circular breeding ponds can avoid dead corners of water flow, the land utilization rate is low, while octagonal breeding ponds can improve land utilization while taking into account water exchange and sewage discharge, and are easy to build. Adopt octagonal breeding pond; and the inner wall of octagonal breeding pond has corners, so when using conventional automatic salvage equipment, there will be places that are difficult to salvage, which will affect the salvage effect
