Description
Technical field
The present invention relates to the volume meausring apparatus technical field in a kind of engineering, environmental science and biology, especially relate to a kind of volume weigher.
Background technology
At modern project technical field, geological sciences field, environmental science and life science, often need to measure certain parts, soil, rock or the histoorgan volume as root system, blade.When producing certain special substance parts, in order to save during the material of the especially super costliness of price, the precise volume calculating the whole production schedule this parts material required may be needed, rationally to purchase.If these parts are more regular, so the volume of these parts can easily calculate, then according to the density calculation buying gross mass of producing total number of components, this parts volume and this special substance, gross mass=part sum x volume of part x part material density can namely be purchased.But the volume overwhelming majority of parts is all irregular positive, is difficult to computation and measurement.In addition, some detection needs density measurement, as everybody buys the jewellery of various noble metal, when how to distinguish that when destroying its shape whether it is adulterated or whether purity is enough, if when can measure the accurate density of this kind of jewellery, the true and false and the value of these jewellery can be judged.In geology or environmental science, often need to calculate the rock of the same race of Different sources or the density of different rock fast, or the density of various soil, to understand its character or to analyze and research further.At life science, for special test object, sometimes need to measure the volume of root system of plant or the volume etc. of blade.And, because of detecting, primitive part or material being destroyed, being often also difficult in a practical situation make us accepting.
At present, for all Similar Problems in these lives, engineering or scientific research, mainly solve with drainage or Plethysmometry.Draining ratio juris: fill water with a container, then put into object under test, treats that water overflows, and then weighs the weight of overflowing moisture, then with 1cm
3the water volume of the spilling that/g water-mass density calculates and object under test volume.But with the existing various container on market, drainage is difficult to accurately measure small size object, as the volume of ring or pin, and measuring accuracy is poor.Plethysmometry principle: with a container with a scale as graduated cylinder, load a certain amount of water, the initial volume of record water, then puts into object under test, and the water surface rises, record final volume, then calculates difference and the object under test volume of final volume and initial volume.Equally, with the existing various container on market, Plethysmometry is also difficult to accurately measure small size object, and as the volume of ring or pin, and measuring accuracy is also poorer than drainage.Visible, for above-mentioned variety of problems, current also none easy, accurate, easy solution.
Summary of the invention
The object of the invention is to provide a kind of volume weigher for the deficiencies in the prior art.Thus effectively solve the problems of the prior art.
For achieving the above object; the technical scheme that the present invention takes is: described a kind of volume weigher; be characterized in comprising main body; mesh sheet is provided with in described main body; body top has been threaded connection top cover, and main body and top cover connection are provided with rubber washer, and described top cover comprises top cover tip; be provided with protection Luo Tai bottom top cover tip, protective sleeve is connected by screw thread is set in top cover tip external with protection Luo Tai.
