River snail catching device suitable for stream

Abstract

The invention discloses a river snail catching device suitable for a stream. The river snail catching device comprises a river snail catching mechanism used for catching river snails, a river snail filtering mechanism used for filtering impurities in the river snails and a walking mechanism used for pushing to walk, a connecting rod is welded at the right side of the river snail catching mechanism; and the right side of the river snail catching mechanism is fixedly connected to the right side of the walking mechanism through the arranged connecting rod, the two sides of the connecting rod arefixed through bolts, and a third long rod is arranged in the river snail filtering mechanism. After a roller shaft presses down aquatic plants, the river snails are extruded when a first spring is pressed down, the river snails can be clamped and contracted when the roller shaft leaves, and therefore the river snails can be conveniently collected; and a spiral blade rotates along with the first spring, a layer of transverse plate is arranged on the spiral blade and can be used for pulling up the river snails and then transporting the river snails up, the roller shaft rotates on a first long rod, and a round ring is installed on the roller shaft, so that the aquatic plants can be well pressed down, the aquatic plants present a forward falling mark, and the river snails can be captured moreconveniently.

Description

technical field [0001] The invention belongs to the technical field of snail capture, and in particular relates to a snail capture device suitable for small streams. Background technique [0002] Field snail generally refers to the mollusk of the family Snail, which belongs to the mollusc phylum Gastropoda Probranchia and the field snail of the family Snail family. It is harvested in autumn. Chinese round snails and Chinese round snails are common in fresh water. Currently, snails are caught by hand, and some nets are used to pick them up. [0003] Fishing is too troublesome. There are some aquatic plants growing in the water of the creek. During the fishing process with the net, the net will catch a large amount of aquatic plants. Contents of the invention [0004] The purpose of the present invention is to provide a kind of snail catching device suitable for creeks, to solve the problem of the existing snail catching device suitable for creeks proposed in the above-ment...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of snail catching device suitable for creeks, to solve the problem of the existing snail catching device suitable for creeks proposed in the above-mentioned background technology. There are a lot of aquatic plants growing, so the capture efficiency is very poor
