Description

Shear type fishing device for short pearls

Technical Field

The invention relates to the technical field of environment-friendly equipment, in particular to a shear type fishing device for short pearls.

Background

Although the short pearl belongs to the stem aquatic weed, the stem is not upright, but crawls to grow on the bottom. Because the creeping branches which grow in a creeping way spread out and are spread on the whole bottom, the blades on the creeping branches grow densely, the propagation speed of the short pearls is faster as the grass plots feel, and when the propagation speed is too fast, the oxygen in the water can be absorbed, on one hand, the water quality is influenced, and on the other hand, the organisms in the water can be influenced.

For example, CN 107700446a proposes a machine for fishing waterweeds, which solves the technical problems of difficulty in cleaning waterweeds, pollution of water resources due to excessive use of pesticides, and danger of drowning caused by manual cleaning, and mainly scrapes the waterweeds through the use of a conveyor belt and a splitter plate to finish the cleaning of waterweeds, but the roots and stems of the waterweeds are long, such as short pearls, which can make the grass ball of short pearls firmer when the roots and stems are coiled together, and are difficult to cut off only through the splitter plate, thereby resulting in incomplete fishing, and after the waterweeds are fished, the weight of the machine body is increased due to the large amount of water, thereby consuming more resources to start the machine body.
