Description

Carp and crucian carp spawning investigation underwater aquatic grass harvester

technical field

The utility model relates to a bottom aquatic weed harvester for carp and crucian carp spawning investigation.

Background technique

There are a lot of aquatic plants growing in lakes, rivers and reservoirs, which provide good attachments for carp, crucian carp and other fish that lay sticky eggs, and these aquatic plants are often the places where schistosomes gather. Aquatic scientific research personnel are infected with schistosomiasis due to inadvertent contact with water bodies and aquatic plants in the epidemic area when conducting spawning field surveys and collecting aquatic plants in the epidemic area, causing great harm to the health of researchers. The traditional method of harvesting aquatic plants is to pick them up with a sickle or a pod machine. The sickle needs to be inserted into the water body to grab and cut. When the water depth exceeds 50cm, the aquatic plants are difficult to harvest, and the operator is easily infected with schistosomiasis. The tools are cumbersome, laborious, and easy to wear out fingers, and the aquatic plants are not easy to cut off.

Contents of the invention

The purpose of the utility model is to provide a carp and crucian carp spawning investigation water bottom waterweed harvester which is convenient to use, good in safety and high in working efficiency.

The underwater aquatic grass harvester for carp and crucian carp spawning survey of the utility model includes a pull rod, a cutting knife and a grass harvesting cage. There are symmetrical installation holes, one end of the pull rod is threaded, the pull rod is threadedly connected with the screw hole of the cutting knife, and fixed with bolts, the pull rod and the cutting knife form an angle of 40-50 degrees, and the front end of the grass collection cage is composed of a pole and a mesh The opening and the rear end are sealed by mesh sheets, and the front opening end of the grass collecting cage is fixedly connected with the mounting hole on the cutting knife through a support rod.

The underwater aquatic grass harvester for carp and crucian carp spawning survey of the utility model is used by scientific research personnel in the survey of underwater aquatic plants in carp and crucian carp spawning grounds. By manually pulling the pull rod backwards, the cutting knife quickly cuts off the aquatic plant stems and enters the grass harvesting cage. , people can collect aquatic plants at any time, avoid contact with water bodies, reduce the probability of schistosomiasis infection, it is easy to carry and use, and has high work efficiency.
