Technical field
The utility model relates to a kind of new fish otolith clamp for grinding.
Background technology
Fish are to have become requisite protein source in people's life gradually.Current ecological deterioration and propagating artificially under the situation of dominate, people like eating the aquatic products of growing at natural environmental condition more.And because excessive fishing in recent years causes fishery resources sharply to descend, so by fish age-growth situation is studied; grasp the fish growth rule; understand the fish population situation, formulate the relevant policy of fishing for, protecting fishery resourses is research emphasis now.
Otolith is to identify and the ideal material of increment study that its special wheel line structure can well reflect age, growing state of fish and the environmental condition of perching the fish age.And, just can observe wheel line structure after need grinding otolith simultaneously because the otoliths of fish compares lessly.Not by certain training, be difficult to reach the grinding requirement of the best, mainly there are following two problems in the otolith process of lapping:
1, otolith grinds inhomogeneous
Because the size of otolith, shape, quality etc. is irregular, need to have determined higher grinding technique.Mostly grinding in the past is free-hand carries out, and whether very difficult like this grasp is ground and reached requirement.If the otolith overgrinding has promptly ground off the otolith core, then otolith can not use, and has also wasted time and manpower, and what is more important has also been wasted valuable otolith material.Though how to grind with machines such as grinders now, because dynamics and time are difficult to control, the phenomenon of otolith wearing and tearing still is difficult to avoid.
2, the otolith core is not ground fully or overgrinding
The core of otolith is the starting point that otolith is initially taken turns line, so otolith suitably is ground to the accuracy that core will influence the age evaluation.If the otolith core fails fully to grind, then the age of core can't read; If instead otolith core overgrinding, the age of core will be left in the basket.
3, slide easily drops
In grinding in the past, often in carrying out the process that machine grinds, slide breaks the slide that has an otolith easily or otolith departs from the grinding direction.Slide breaks and then can not reuse, and because otolith is very little, seeks once more and get up to have very big difficulty, has brought a lot of difficulties to experiment.
3, the damage of operator's hand is big
The grinding of otolith need be carried out the operator and clip otolith and grind for a long time on sand paper with finger, and this can cause the damage of finger inevitably, even swelling is hemorrhage, and various aspects such as from now on work and life have been caused tremendous influence.The injury that this damage brought is not only on operator's health, also its psychology is had to a certain degree strike simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of new fish otolith clamp for grinding.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of fish otolith clamp for grinding, comprise one by aluminum alloy materials shell of making and the iron balancing weight that is embedded in the described shell, described shell is divided into three sections, the top section is hemispherical, the top in stage casing is cylindric, and the bottom is coniform, and end section is cylindric, at the bottom of described shell the bottom surface of section be provided with one with the suitable square indentations of slide, respectively offer a discharge outlet radially at four angles of described square indentations.
The bottom land frosted of described square indentations is handled.
Fish otolith clamp for grinding of the present utility model top section is hemispherical, enables to press close to well the centre of the palm; The top in stage casing is cylindric, and the bottom is coniform, and the finger of can fitting well is fit to hold and carries out grinding operation; Be provided with in the bottom surface of end section one with the suitable square indentations of slide, be convenient to place slide.
The bottom land frosted that important characteristic of the utility model is exactly a square indentations is handled.And when handled by frosted the metal surface, because the stability of metallic bond under the situation of not destroying metal structure, has enlarged spacing therebetween, it was long-pending to have increased metallic surface simultaneously.When water enters these spacings, because the existence of Brownian movement, make very fast even distribution of water and metal surface.Water is polar molecule, because dipole moment is very strong, thus mainly show as dipole-dipole force in the intermolecular interaction, and in hydrone, also have the existence of hydrogen bond.Because these two kinds of active force actings in conjunction all couple together each hydrone closely, so also make to link together at the water of metal surface and the water on the slide, thereby overcome slide gravity, make that slide is difficult for dropping.By the pressure of hand slide, further make intermolecular distance dwindle, this moment, intermolecular force mainly showed as gravitation, has further strengthened the connection between the hydrone, thereby slide and metal substrate are fit together firmly.
The utility model increases the iron-based weight material in the enclosure, has increased the weight of whole anchor clamps, makes coefficientoffriction increase, according to F
Rub=μ F makes that like this frictional force increases simultaneously, and slide is more difficult dropping in process of lapping.
The utility model respectively offers an osculum at four angles of square indentations, in the time of can making the applying slide, in time unnecessary water is discharged, and after having ground, slide is taken off simultaneously.
The utility model holds shell by slide is embedded in the square indentations of anchor clamps bottom surface, thereby in process of lapping, hand does not contact otolith, the pressure that can control in weight by homogeneous material and the hand reaches best grinding effect, facilitates to experimentation.
The existing Ginding process of the utility model is compared, and has following beneficial effect and substantive distinguishing features:
1, otolith grinds evenly;
2, the otolith core is ground fully and can overgrinding;
3, slide is difficult for dropping;
4, operator's hand not damaged.
