Spring contraction type fish driving device and working method thereof

Abstract

The invention relates to a spring contraction type fish driving device which is characterized in that a lifting screw penetrates through a trolley control box from bottom to top and is fixedly connected with a motor lifting seat, the pressure between a metal friction wheel and the upper end face of a pool can be controlled by adjusting the lifting screw, and the metal friction wheel provides advancing power for a trolley; pool end face guide wheels are arranged on the two sides of the metal friction part, and rolling friction is formed between the pool end face guide wheels and the pool end face; the trolley control box is provided with an aluminum profile support and a pool end face guide wheel seat, and the pool end face guide wheel is installed on the pool end face guide wheel seat. An aluminum sliding rail is installed on the aluminum profile support, a sliding block capable of sliding along the aluminum sliding rail is arranged on the aluminum sliding rail, the vertical optical axis supporting seat is installed on the sliding block, a pool wall guide wheel shaft is arranged in a hole of the sliding block, a pool wall guide wheel is arranged on the pool wall guide wheel shaft, and a tension spring enables the pool wall guide wheel to be tightly attached to the pool wall to automatically adjust the distance between the pool wall guide wheel and the trolley control box. The brush wheel comprises a brush column and a universal wheel at the bottom of the brush column, and the brush wheel clings to the pool wall by means of elasticity of the brush to prevent fishes from escaping from gaps.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a factory automatic fish collecting device and a working method thereof. Background technique [0002] Most of the existing fish collection technologies are applied in ponds and net cages. Fishermen attract fish from the vicinity through lights, sounds, lasers, electrical stimulation, etc., and finally lift the fish out of the water by netting. These methods are very irritating to fish, and the amount of fish caught largely depends on the proficiency of workers. [0003] Industrial aquaculture has a better space environment, and the bottom of the pond is relatively flat. It is easier to use seine technology to encircle and concentrate farmed fish. However, artificial seine is labor-intensive, takes a long time, and has a high fish damage rate. Contents of the invention [0004] The object of the present invention is to provide a device that can automatically catch fish in the purse ...
