Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
With reference to Fig. 1, the determinator of portable bivalve shellfish closed shell flesh pulling force of the present invention, comprise: base 1, be fixed on the gag 2 on base 1, A-frame 3, be arranged on the leverage 4 on the top of A-frame 3, and be arranged on the strain gauge 5 between leverage 4 and gag 2, strain gauge 5 is digital-scroll technique strain gauge preferably.
Wherein, base 1 has certain thickness, guarantees that the shell of bottom side in mensuration process can not touch ground, thus avoids the reading affecting strain gauge; Gag 2 is in tong-like, opening is flat, and point rear portion, the front portion of opening is wide, there is protruding draw-in groove 12 at rear portion, has both facilitated gag 2 and has stretched in shell, in turn ensure that the length fixedly stretching into bivalve shellfish shell is consistent, thus guarantee the accuracy that closed shell flesh pulling force measures; Three legs of A-frame 3 rotate around same pivot 6, the bottom of leg is provided with annulus 7, spacing hook 8 is hung with between the annulus 7 of adjacent two legs, during use, three legs are separately formed A-frame 3, then by spacing hook 8, A-frame 3 is fixed, when not using, three legs are retracted to a branch of, greatly save space, and easy to carry; Upper end, the lower end of strain gauge 5 are all connected with leverage 4, gag 2 by coupling hook 9, easy accessibility.
As the preferred scheme of one, each leg of A-frame 3 is provided with two annulus 7, only can inserts a spacing hook 8 in each annulus 7, thus the steadiness of A-frame 3 can be improved.
As the preferred scheme of one, be rotationally connected between leverage 4 and A-frame 3 by attaching nut 10, attaching nut 10 can disassemble from A-frame 3, thus leverage 4 can be separated with A-frame 3, is convenient for carrying.
Determinator of the present invention, its leverage and A-frame is detachable, A-frame can be amounted to into a line, strain gauge and can disassemble from determinator, after splitting, the volume of whole device is only 0.10m × 0.15m × 0.50m, weight is only about 2.0Kg, not only be convenient for carrying and operate, and assembling fast, very convenient field condition is measured.
Due to the bivalve shellfish of the same race of different bivalve shellfish or different size, need the openings of sizes of gag 2 different, so, as the preferred scheme of one, lever stress levels fixture 11 is also provided with between leverage 4 and A-frame 3, be used for regulating the size of gag 2 opening, thus improve the suitability of determinator of the present invention.
As the preferred scheme of one, the opening thickness of gag 2 is less than 2mm, is more convenient for gag 2 to stretch in shell.
Utilize said determination device to measure the method for bivalve shellfish closed shell flesh pulling force, comprise the following steps:
(1), by bivalve shellfish stretch into the opening of gag 2, make the draw-in groove 12 of the bivalve of shellfish and the projection of gag block together;
(2), the end of light pressure leverage 4, observe the reading of strain gauge 5;
(3), after the stable reading of strain gauge 5, this reading F is recorded
strain gauge;
(4), calculate closed shell flesh pulling force, formula is:
F
close=L
1× F
strain gauge/ L
2
Wherein, F
close: closed shell flesh pulling force;
L
1: the coupling hook 9 on gag and the horizontal range between the rotating shaft 13 of gag;
L
2: the horizontal range between the leading edge of the draw-in groove 12 of gag and the rotating shaft 13 of gag.
Rear portion due to the opening of gag has protruding draw-in groove 12, when measuring, alignd with the draw-in groove 12 of the projection on gag in shell outer end, thus can guarantee that the length fixedly stretching into bivalve shellfish shell is consistent, and then ensure the accuracy that closed shell flesh pulling force measures.
It should be noted that, above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
