Adult frog screening device for breeding

Abstract

The invention discloses an adult frog screening device for breeding. The adult frog screening device comprises two side plates which are arranged vertically and in parallel. A base is fastened betweenthe two side plates, and a feeding platform is fixed to the base. A horizontal inner groove and a pit communicated with the inner groove are formed in the base. A sliding plate is slidably connectedinto the inner groove, and an inner cavity is formed in the sliding plate. An upper hole and a lower hole, which are communicated with the outside, are formed in the inner wall of the inner cavity. The adult frog screening device has the advantages that bullfrogs with standard body sizes press an upper slider due to heavy weights when moving to the sliding plate, a friction plate is enabled to move upwards, a leftward counterforce is applied to the sliding plate when the bullfrogs jump forwards, and the sliding plate is enabled to move leftwards rapidly; in this process, because the counterforce is not enough for the bullfrogs to complete jumping in the direction of the feeding platform due to leftward movement of the sliding plate, the bullfrogs can only jump upwards in situ and fall intothe pit; otherwise, small bullfrogs cannot fall into the pit.

Description

technical field [0001] The invention relates to the technical field of bullfrog breeding, in particular to an adult frog screening device for breeding. Background technique [0002] Bullfrogs are amphibious animals with strong adaptability to the environment. They can not only catch insects when they are active at night, but also have medicinal value. They can effectively improve various nutritional components of the human body, improve human immunity and resistance, and have the effect of health care and anti-aging. Efficacy, in order to maintain a balance with market demand, there are more and more bullfrog farmers in the society; [0003] In the process of bullfrog breeding, they are often bred in batches, but the growth rate of the same batch of bullfrogs cannot be kept consistent, that is, there will always be some bullfrogs that grow slowly, and when supplying to the market, the entire batch of bullfrogs with obvious differences in size Direct supply will lack the bid...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the size difference of the same batch of bullfrogs in the prior art is relatively obvious, which leads to the problem of low bidding ability in packaging and selling, and proposes a breeding adult frog screening device
