Fishpond drop net instant catching device

Abstract

The invention discloses a fishpond drop net instant catching device. The device comprises a drop net, a net supporting device and a net lifting device, wherein the drop net comprises a net body which is of a cubic groove-shaped structure after being unfolded, a plurality of pull rings which are distributed along the opening edge of the net body at intervals, and pull ropes which are inserted in the pull rings in a penetrating manner; each pull rope penetrates through the three edges of the net body and forms two pulling ends; the net supporting device is arranged on the periphery of the drop net and comprises four first pulleys, and the four first pulleys are correspondingly arranged at the four corners of the drop net and matched with the pull ropes. The net lifting device comprises a lifting frame used for lifting the longitudinal height of the two pulling ends of each pull rope, a counter weight connected to the pulling ends of the pull rope, and a switch device used for locking the position of the counter weight. According to the device, finished fishes can be gathered and fished quickly, the fishing efficiency is effectively improved, and the finished fishes are gathered in a small range to facilitate manual sorting.

Description

technical field [0001] The invention belongs to the technical field of fishery fishing, and in particular relates to an instant fishing device for lifting a net in a fish pond.
