Abstract
The utility model discloses a quick qualitative benthos collection net, including handle and write by hand net, the write by hand net includes the screen frame of being connected with the handle and the string bag of establishing on the screen frame and can strutting backward, and the write by hand net is equipped with the lid net that can open or close write by hand net net gape in the front side of screen frame, and the bottom of screen frame is equipped with a plurality of spike -tooths that stretch out downwards. When gathering benthos, the operation of will launching of collection personnel, handheld handle inserts the aquatic to the spike -tooth of screen frame lower extreme, rocks to move ahead in the bed mud, and the benthos in the bed mud will fall into the lid net along with the stirring of spike -tooth, and the lid net can filter some great debris, rubble etc. And along with moving ahead of write by hand net, benthos will finally fall into the string bag of write by hand net, washs the back in aqueous, takes the bank with the net, and benthos can in netting with the tweezers picking. The utility model discloses can utilize the bed mud in the clean network pocket of waters water own, can fully catch benthos, the waste of manpower and materials when the reduction is washed to the bed mud greatly.
Description
Technical field
This utility model is used for benthon harvester technical field, particularly relates to a kind of fast qualitative benthon and gathers net.
Background technology
Scientific research field exists a lot about benthic harvester at present, but major part is all to take acquisition benthon after bed mud rinses in mesh screen, and the collection of bed mud and flushing need to expend a large amount of manpower and materials, and these devices are relatively cumbersome, inconvenient operation, carries also inconvenient.
Utility model content
For solving the problems referred to above, this utility model provides a kind of fast qualitative benthon to gather net, for in river course, shallow sea can enter the benthic qualitative collection of shallow water area of people with beach etc., the bed mud in the waters water body cleaning string bag itself can be utilized, can fully catch benthon, significantly reduce the waste of manpower and materials when bed mud is rinsed.
This utility model solves its technical problem and be the technical scheme is that a kind of fast qualitative benthon gathers net, including handle and the fishing net being located at described handle, at its lower end, described fishing net includes the screen frame being connected with described handle and is located on described screen frame and can be to the string bag of rear distraction, described fishing net is provided with the cover net that can open or close fishing net network interface in the front side of screen frame, and the bottom of described screen frame is provided with some spike-tooths extended downwardly from.
It is further used as the improvement of technical solutions of the utility model, the bottom of described screen frame has straight underframe, the two ends of underframe are provided with pivot hole, the lower end of described cover net is provided with the pivot loaded in described pivot hole, the top of screen frame is provided with hanging handle, and the top of cover net is provided with the lanyard can being connected with described hanging handle.
Being further used as the improvement of technical solutions of the utility model, described cover net is wire netting, the concave surface of the oriented described string bag sunken inside of described expanded metal.
Being further used as the improvement of technical solutions of the utility model, the mesh of described cover net is more than the mesh of the described string bag.
The beneficial effects of the utility model: when using this utility model to gather benthon, collector's water to be descended operation, hand-held handle, the spike-tooth of screen frame lower end is inserted in water, bed mud rocks and moves ahead, benthon in bed mud will fall in cover net along with the agitation of spike-tooth, cover net can filter some bigger foreign material, rubbles etc., along with moving ahead of fishing net, benthon will eventually fall in the string bag of fishing net, after cleaning in water, net is taken bank, with tweezers picking net mesobenthos.This utility model in river course, shallow sea can enter the benthic qualitative collection of shallow water area of people with beach etc., the bed mud in the waters water body cleaning string bag itself can be utilized, can fully catch benthon, significantly reduce the waste of manpower and materials when bed mud is rinsed.
