Abstract
The utility model relates to a dip net for crab seedling inspection. The dip net comprises an outer frame, an inspection net and a handle, wherein the handle is arranged on the outer frame, and the inspection net is arranged in the outer frame; the inspection net is formed by two layers of net bodies, and meshes of the two net bodies of the inspection net are different in size, the net body with smaller meshes has water-absorbing property and elasticity, while the net body with larger meshes is non-elastic; and an interval is formed between the two layers of net bodies of the inspection net. The dip net for crab seedling inspection has the advantages that the health condition, limb health condition and specification of crab seedlings in a nursery pond can be inspected conveniently and quickly at any time by applying the dip net in the crab seedling process, and counting can be performed efficiently, monitor to the crab seedling condition at any time can be greatly facilitated in the nursery process, situations can be found as soon as possible, and the success rate of nursery can be guaranteed.
Description
Technical field
The utility model belongs to juvenile crab and cultivates the testing tool technical field, particularly relates to juvenile crab and inspects with diddle-net.
Background technology
Aquaculture is the current very important industry of China, for improving fisherman's income, enriches China's Dietary Pattern of Residents and plays a part huge.Eriocheir sinensia, mud crab, swimming crab are China's most important culturing economic crab classes, and it is that these economic crab cultivate movable important prerequisite that the artificial seed breeds, and plays conclusive effect for the seed supply.And in the seed breeding process, often need to the seed in the nursery pond be inspected or be counted, need one simply and easily instrument operate.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of juvenile crab and inspects with diddle-net, lacks the problem of inspecting with count tool to solve in the prior art in the juvenile crab reproductive process.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of juvenile crab to inspect with diddle-net, comprise housing, inspect net and handle, on the described housing handle is housed, be equipped with in the described housing and inspect net, the described net of inspecting is made of two-layer dictyosome, described width of mesh difference of inspecting the two-layer dictyosome of net, and the described less dictyosome of net meshe of inspecting has water imbibition and elasticity, the described larger dictyosome of net meshe of inspecting does not have elasticity, between the described two-layer dictyosome of inspecting net the interval is arranged.
Described housing is rectangle, on the described housing rectangle medial surface two grooves are arranged, a described housing wherein limit is dismountable, the described two-layer dictyosome of inspecting net can snap in along the groove of housing rectangle medial surface inspects net, the described two-layer dictyosome edge of net of inspecting is with the edge banding frame edge sealing, and the thickness of edge banding frame becomes interference fits with the groove of housing rectangle medial surface, and the dismountable frame of described housing is with bolt fastener and adjacent two edge joints.
Interval 2-15 millimeter between the described two-layer dictyosome of inspecting net.
The described two-layer dictyosome of inspecting net, the order number of large mesh dictyosome are below per inch 20 orders, and the order number of fine mesh dictyosome is more than per inch 26 orders.
Described handle end is a blind hole, and described blind hole adds long handle with internal thread and external screw thread in order to connection.
Described housing and handle are made with plastics and stainless steel material.
The described fine mesh dictyosome of inspecting net is made by nylon material.
The described large-mesh dictyosome of inspecting net is made by stainless steel material.
Beneficial effect
The utility model has the advantage of, in the crab class seedling raising process, use the utility model, can inspect at any time health status, limbs health status, the specification size situation of the juvenile crab in the nursery pond quickly and easily, and can count efficiently, greatly facilitate seedling raising process the situation of juvenile crab is monitored at any time, find early situation, guarantee the success rate of growing seedlings.
