The invention relates to the field of
fishing technology, and discloses an efficient automatic
fishing device based on grid hole changes. The efficient automatic
fishing device comprises a central
pipe, wherein limiting circular tables are fixed at the left and right ends of the central
pipe respectively; a net cover is fixedly mounted on the inner wall of the limiting circular table at the rightend, and a lead screw is fixedly mounted on the outer wall of the limiting circular table at the left end; mounting columns are fixedly mounted on the lead screw and the outer end of the limiting circular table at the right end respectively; the outer wall of the lead screw is rotationally sleeved with a threaded sleeve; and the threaded sleeve is rotationally sleeved with a fixed ring. Accordingto the efficient automatic fishing device based on grid hole changes, the central
pipe, an arc-shaped plate, the threaded sleeve, the lead screw, the mounting columns, a bait hole and a net cover arearranged, fishes are attracted by the bait, telescopic power is provided for telescopic grids, the
automation degree is high, influence to the
fish growth and propagation environmental is low, injuryto the fishes is low, and the fishing quality is high; and through the telescopic grids, a large number of fishes can
drill in conveniently, the operation is simple, labor is saved, the fishing efficiency is high, and the practicability is high.
