Description
Technical field
The utility model belongs to hydraulic engineering technical field, is specifically related to a kind of fish-egg bolter.
Background technology
In recent years, in water conservancy scientific research, in order to grasp in river the early stage stock number of producing Drifting egg fish, often need the quantity of monitoring river Mesichthyes fish-egg.
In actual samples process, the fish-egg containing a large amount of various fish in the sampled water collected, and the most colorless and odorless of fish-egg, will complete fish-egg mask work from water body needs to consume a large amount of manpower and materials, and efficiency is very low.Therefore, in the urgent need to the special equipment of fish-egg separation.
Utility model content
Utility model object: the utility model makes improvement for above-mentioned prior art Problems existing, namely the utility model discloses fish-egg bolter.
Technical scheme: fish-egg bolter, comprises the first sieves, the second sieves and the 3rd sieves,
The mesh size of described first sieves is 35 orders, and the internal diameter of described first sieves is 35cm, and the exterior bottom of described first sieves is provided with the first spacing preiection;
The mesh size of described second sieves is 45 orders, and the internal diameter of described second sieves is 35cm, and the exterior bottom of described second sieves is provided with the second spacing preiection;
The mesh size of described 3rd sieves is 70 orders, and the internal diameter of described 3rd sieves is 35cm, and the exterior bottom of described 3rd sieves is provided with the 3rd spacing preiection;
The bottom of described first sieves and the top of described second sieves are socketed, and the bottom of described second sieves and the top of described 3rd sieves are socketed.
Further, the lower limb of the first spacing preiection is 0.5cm to the distance of the bottom margin of the first sieves.
Further, the lower limb of the second spacing preiection is 0.5cm to the distance of the bottom margin of the second sieves.
