Description

Technical Field

[0001] The utility model belongs to the technical field of male and female mosquito pupa separation, and particularly relates to a semi-automatic male and female pupa separation device. Background Technique

[0002] The sterile insect technique (SIT) is a mosquito control technique that sterilizes male mosquitoes by irradiation and then controls target mosquitoes by continuously releasing sterile male mosquitoes. In the process of practice, gender separation must be carried out at the pupa stage to separate male and female pupae.

[0003] Currently, the commonly used method is to utilize the difference in the individual sizes of male and female pupae, with female pupae being larger and male pupae being smaller, for gender separation.

[0004] The existing flat manual separator has no supporting larva and male and female pupa collection devices, and the overall appearance is not aesthetic. After pouring the mixture of larvae and male and female pupae to be separated, it is necessary to manually add water continuously to form a water flow impact. This action needs to be repeated many times during separation, resulting in a large labor intensity and low work efficiency, thus causing low gender separation efficiency. The manually poured water flow is discontinuous and the flow rate cannot be controlled, which is not conducive to effective separation. When separating genders, it is necessary to continuously pour water into the flat separator, consuming a large amount of water. The poured water is directly discharged into the sewer and cannot be recycled, resulting in waste of water resources. Content of the Utility Model

[0005] In view of the problems existing in the above-mentioned prior art, the utility model provides a semi-automatic male and female pupa separation device. The technical problem to be solved by the utility model is to reduce manual operation, improve separation efficiency, and save water resources during the pupa separation process.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A semi-automatic male and female pupa separation device, comprising: a bracket, a fixing plate, an adjusting plate, and a spraying device. The fixing plate is connected to the bracket. The fixing plate and the adjusting plate are arranged opposite to each other to form a structure with upper and lower openings. The fixing plate and the adjusting plate are connected by a gap adjusting member. The gap between the fixing plate and the adjusting plate gradually decreases from top to bottom. The spraying device is connected to the bracket and is located above the gap formed by the fixing plate and the adjusting plate.

[0008] Further, the gap adjusting member is used to adjust the gap distance between the adjusting plate and the fixing plate. The gap adjusting member is at least divided into two rows, upper and lower. The upper row of gap adjusting members is located at the upper ends of the adjusting plate and the fixing plate, and the lower row of gap adjusting members is located at the lower ends of the adjusting plate and the fixing plate.

[0009] Further, the gap adjusting member is made of a transparent material, and scales are marked on the gap adjusting member.

[0010] Furthermore, the semi-automatic male and female pupa separation device further includes a diversion trough, which is located below the gap formed by the fixed plate and the adjustment plate.
