Tadpole seedling collecting device

Abstract

The invention discloses a tadpole seedling collecting device. The tadpole seedling collecting device comprises a collecting box, wherein a notch is formed in the outer wall of one side of the collecting box; first wave plates are fixed to the two ends of one side of the inner wall of the bottom of the collecting box; second wave plates are fixed to the two ends of one side of the inner wall of thebottom of the collecting box; the second wave plates are positioned in the two first wave plates; fixing rods are fixed to the outer walls of one sides of the two second wave plates; a rotating ringis rotationally connected between the fixing rods; a plurality of fan blades are fixed to the outer wall of the rotating ring; limiting plates are fixed to the two ends of one side, close to the firstwave plates, of the collecting box; and a feeding net plate is fixed between the limiting plates. According to the tadpole seedling collecting device, a first glass plate and the second wave plates can prevent large-size organisms in water from entering the collecting box, so that tadpoles are prevented from being eaten, the fan blades rotating along with water flow can prevent aquatic plants andother sundries from entering the collecting box, meanwhile, a retention groove is formed, so that air circulation is fast, the tadpoles are attracted to be gathered, and subsequent collection is facilitated.

Description

technical field [0001] The invention relates to the technical field of tadpole seedlings, in particular to a tadpole seedling collecting device. Background technique [0002] Tadpoles are the larvae of frogs and toads, also known as toad eggs. The newly hatched tadpoles have a spindle-shaped body without limbs, mouth and internal gills. They have long flat tails and branched external gills on both sides of the head. They absorb on aquatic plants and rely on the remaining yolk for nutrition. . Mainly live in groups. When tadpoles mature, they begin to metamorphose, gradually growing limbs, and then gradually degenerate their tails through apoptosis, and finally grow into frogs or toads. In order to study tadpoles, it is usually necessary to study them in rivers or rice fields. Wild tadpoles were collected and studied by the control variable method. [0003] However, when conventional tadpole seedling collection devices are working, they cannot isolate other organisms from...

AI Technical Summary

Problems solved by technology

[0003] However, conventional tadpole seedling collection devices cannot isolate other organisms from entering the collection device when they are working, which will cause other organisms, such as shrimps, crabs or snakes, to be collected by the collection device after certain tadpoles are collected in the collection device. collected, and then these creatures will eat all the tadpoles collected in the collection device, resulting in low collection efficiency. Therefore, we need to design a tadpole seedling collection device to improve this problem
