Abstract
The invention relates to the field of benthic organism sampling, in particular to a benthic organism sampler which comprises a sampling box, a piston, a pull rod and a hollow sampling box rod, wherein the piston is arranged in the sampling box; an opening is formed in one end of the sampling box; the other end of the sampling box is connected with the sampling box rod; the sampling box rod sleeves the pull rod; graduations are marked on the pull rod; one end of the pull rod is connected to the piston; the other end of the pull rod is placed at the outer part of one end, far away from the sampling box, of the sampling box rod. When the benthic organism sampler is used for sampling benthic organisms surviving in soil at the bottom of the water body in a middle-shallow water body, the moving distance of the piston in the sampling box is read out conveniently by observing the graduations on the pull rod, so that the sampling depth is controlled. Since the cross-sectional area of the opening of the sampling box is given, the current sampling amount can be known easily by reading out the moving distance of the piston in the sampling box, and the sampling can be performed relatively accurately according to the quantity demanded.
Description
Technical field
The present invention relates to bottom-dwelling and gather field, in particular to a kind of Bentonic organism collector.
Background technology
There is polytype Bentonic organism collector in the market, but in the process that water body mesobenthos diversity is studied, the narrower river course of in some shallow water river channels, shallow water river channel, current or shallow lake collection is usually needed to survive in bottom-dwelling in mud, existing Bentonic organism collector may and be not suitable for sampling in this environment, and it can not control collection capacity exactly.That is, Bentonic organism collector of the prior art is not easy to gather bottom-dwelling by demand more exactly in middle either shallow water body.
Summary of the invention
The object of the present invention is to provide a kind of Bentonic organism collector, be not easy to gather benthic problem by demand more exactly in middle either shallow water body to improve Bentonic organism collector of the prior art.
The present invention is achieved in that
A kind of Bentonic organism collector, comprise the vasculum bar of vasculum, piston, pull bar and hollow, described piston is placed in described vasculum, one end of described vasculum is provided with opening, the other end of described vasculum is connected with described vasculum bar, and described vasculum bar is sheathed on described pull bar, and described pull bar is provided with scale, one end of described pull bar is connected to described piston, and the other end of described pull bar is placed in the outside of described vasculum bar away from one end of described vasculum.
Further, the sidewall of described vasculum is provided with multiple hole.Utilize above-mentioned multiple hole, the water entering vasculum can flow to outside vasculum effectively, to improve the quality gathering thing.
Further, described vasculum bar is removably connected to described vasculum.When vasculum bar is connected with vasculum removably, user can make vasculum bar and vasculum be separated when carrying larger this Bentonic organism collector of overall dimensions, thus is convenient to user and carries.
Further, described Bentonic organism collector also comprises first handle, and described first handle is placed in described pull bar one end away from described piston, and the surface of described first handle is provided with the first skid resistant course.When using this Bentonic organism collector, user can utilize first handle to control the motion of pull bar relative to vasculum bar, i.e. the motion of control piston in vasculum, makes it possible to control collecting work; In addition, the first skid resistant course that first handle is arranged can prevent the hand of user from skidding, and is convenient to user and operates preferably.
