Abstract

The present invention relates to a biological sample selection, and relates to a mechanism for screening only the organisms from the collected sediment, and more particularly to a rectangular mechanism that can be efficiently screened at the place or other places where the collected biological samples.

The core element of the present invention is to separate sediment and biological surface by sea water or fresh water by using a water pump when screening the collected biological specimen, sand, nizil, The siliceous deposits can be pulled out and biological specimens of at least 1 mm in size can be obtained. The filtered biological specimens are collected and collected in the sampler through the opening and closing along the slope of the lower part of the apparatus. By this process, when benthic and biological specimens inhabiting sand, nizil and sanitary sediment are collected, it is a rectangular apparatus for screening biological specimens with a collecting function, which reduces labor and reduces working time. Handles are attached to both sides of the rectangular mechanism for easy movement.

The present invention relates to a biological sample selection, and relates to a mechanism for screening only the organisms in the collected sediment, and more particularly to a rectangular mechanism capable of efficiently screening at the place or other places where the collected biological sample is collected. Stainless steel plates used for biosampling are drilled with holes 1 mm apart.

Korean Patent Publication No. 10-2005-0105812 (2005.11.08) states that after collecting benthic animals, in order to move the benthic creatures out of the sampler, the sampler is flipped and the benthic organisms are removed from the sampler or a tool such as tongs is used. Therefore, it is shown that since the specimens, such as benthic creatures, are moved one by one, the worker must spend a lot of labor to collect the specimens and also spend a lot of time working.

The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to install a retractable discharge device in the rectangular mechanism to collect benthic organisms and biological specimens from the deposits of sand, nizil, and sanitary components. . The benthic creatures and biological specimens are taken from the sediment using excavation tools such as chining and shovels and transferred to the interior of a rectangular instrument for screening biological specimens. When separating benthic organisms and biological specimens from the sediment, use a water pump on site to ensure that the sediment and benthic organisms are separated by seawater or fresh water. At this time, sediment and seawater or freshwater smaller than the diameter of the perforated network of the stainless steel plate with holes 1 mm in diameter on the side and bottom of the apparatus are discharged to the outside, and benthic organisms and biological specimens larger than 1 mm in diameter are opened. It will not pass through and will remain inside the instrument.
Next, when collecting benthic and biological samples filtered through the perforated network of perforated stainless steel plates having a diameter of 1 mm formed on the sides and bottom of the rectangular apparatus for biological sampling, a water pump is used inside the rectangular apparatus for biological sampling. While spraying seawater or freshwater, benthic creatures and biological specimens are collected on a slope (④) formed at the bottom of the rectangular apparatus for screening biological specimens. At this time, benthic organisms and biological specimens are blocked by the opening and closing hole (⑤) at the end of the inclined surface (④) of the bottom surface is not discharged to the outside.
Next, when the benthic creatures and biological specimens collected along the inclined surface (④) formed on the bottom surface of the rectangular instrument for screening biological specimens are moved to the specimen collection bottle through the opening / closing opening (⑤), a hinge-type opening / closing device having a spring built-in After opening (⑤) manually, the sampler can be put into the sample collection bottle by the sea water or fresh water through the opening and closing along the slope (④) inside the apparatus. After such a series of processes, when the hinge-shaped opening (⑤) with the spring is placed, the opening (⑤) is automatically closed by the spring.

Hereinafter, described in detail by the accompanying drawings as follows.

1 is a perspective view from above of a rectangular instrument for biological specimen selection, showing the appearance of a rectangular instrument for biological specimen selection. Stainless steel plate (①) with a hole of 1mm in diameter forms the whole, and there is a stainless steel body (②) that firmly supports it. An inclined surface ④ is formed on the bottom surface of the mechanism.

2 is an elevation view of a rectangular instrument for screening biological specimens, and two handles (③) are attached to both sides of the apparatus for easy movement of the place, and is effective when collecting biological specimens. As shown in FIG. 1, the stainless steel plate (①) having a diameter of 1 mm in diameter is formed as a whole, and there is a stainless steel body (②) that firmly supports this. When viewed from the side, the inclined surface (④) is formed on the bottom surface, along the inclined surface (④) biological specimens are collected through the opening (⑤) to the sample collector.

FIG. 3 is an elevation view of the rectangular instrument for screening biological specimens, and is a front view of the opening and closing hole ⑤ connected to the inclined surface ④ in FIG. 2.

Finally, FIG. 8 is a perspective view of a state where the opening and closing opening ⑤ is opened, and biological samples are introduced into the sample collection bottle through the opening and closing opening ⑤.

As described above, the sampler according to the prior art has a problem such that a lot of labor of the worker and takes a long time to move the sample organisms collected in the soil and tidal flat from the sampler. Therefore, sediment and seawater or freshwater having a size smaller than the diameter of the perforated network of a stainless steel plate having a diameter of 1 mm in the side and bottom of the rectangular apparatus for screening biological specimens according to the present invention are discharged to the outside, and a hole having a diameter of 1 mm. Larger benthic and biological specimens do not pass through the hole and remain inside the instrument. In addition, benthic organisms and biological specimens collected from sandy, nizil, and siliceous deposits can be easily moved from instruments featuring hinged openings with slopes and springs, reducing worker labor intensity and reducing labor time. You can save.
