The invention also provides a clasping force measuring experimental device for frog breeding, which is operated as follows when in use and comprises the following steps:
the method comprises the following steps: as shown in fig. 1, a male frog to be measured is fixed on a fixed platform 3, the arm of the male frog passes through a through hole 4 and is positioned below the fixed platform 3, then a hoop sleeve II 16 is sleeved at the position of a large arm corresponding to the arm, a hoop sleeve I9 is sleeved at the position of a small arm corresponding to the arm, and male frogs are stimulated to enable the arm to be in a hugging state, namely the large arm and the small arm of the male frog are approximately vertical to each other in the process of mating, in the initial state, a certain included angle is formed between a dynamometer I8 and a comparison block I7, and a certain included angle is formed between a dynamometer II 15 and a comparison block II 14, so that the fact that the tensile force of the dynamometer I8 is parallel to the force application direction of the small arm and the tensile force of the dynamometer II 15 is parallel to the force application direction of the large arm during later-stage adjustment is convenient to judge, and therefore force measurement accuracy of the dynamometer is improved;
step two: after the first hoop cover 9 and the second hoop cover 16 are installed, the state shown in fig. 4 needs to be adjusted through the large arm force measuring mechanism and the small arm force measuring mechanism respectively, the adjusting process is shown in fig. 2 and fig. 5, at this time, the screw rod two 12 is rotated, the slide block two 13 moves upwards along the length direction of the screw rod two 12 under the action of the screw thread, the distance between the slide block two 13 and the corresponding hoop cover two 16 gradually decreases due to the upwards moving of the slide block two 13, therefore, the tensioning mechanism 10 on the dynamometer two 15 needs to be synchronously and continuously adjusted, so that the pull rope 11 is always in the tensioning state, under the action of the pull rope 11, the dynamometer two 15 rotates around the positioning end of the dynamometer two 15 and approaches to the corresponding comparison stopper two 14 until the dynamometer two 15 is attached to the comparison stopper two 14, at this time, when the dynamometer two 15 is attached to the comparison stopper two 14, the touch switch 18 just touches, the touch switch 18 is communicated, so that the circuit is communicated, the indicator lamp 17 is electrified and lightened, namely the position adjustment of the dynamometer II 15 is completed;
In adjusting the tensioning mechanism 10 on dynamometer two 15, the following operations occur: as shown in fig. 7, the worm 23 is rotated, so that the worm 23 drives the worm wheel 24 to rotate, the rotation of the worm wheel 24 drives the winding reel 25 to synchronously rotate, and further the pull rope 11 is wound up to be shortened and tensioned, after the position of the sliding block two 13 is adjusted, the worm wheel 23 is rotated to drive the winding reel 25 to continuously wind the pull rope 11 to be shortened until the pull rope 11 can drive the male frog large arm to open outwards through the hoop sleeve two 16, at the moment, the reading of the dynamometer two 15 is read, namely, the maximum force of the male frog large arm, because the worm wheel and worm transmission structure is adopted, the worm wheel and worm transmission structure generally has a self-locking characteristic, namely, the condition that the unwinding helix angle of the worm is smaller than the contact friction angle of the worm wheel and worm in the worm wheel and worm transmission, the helix angle of the worm 23 in the worm wheel and worm transmission mechanism disclosed in the application is smaller than the contact friction angle of the worm wheel and worm, therefore, the self-locking device can realize self-locking, and can keep the winding reel 25 from reversely rotating at any position of adjustment by utilizing the self-locking characteristic of the self-locking device, so that other fixing mechanisms are not needed, the structure is simplified, and the force measuring accuracy is improved;
Similarly, when the male frog forearm is subjected to force measurement, as shown in fig. 3 and 6, the screw rod I5 is rotated at the moment, so that the slide block I6 moves towards the middle of the base 1 along the length direction of the screw rod I5 under the action of threads, and the distance between the slide block I6 and the corresponding hoop sleeve I9 is gradually reduced due to the movement of the slide block I6, so that the tensioning mechanism 10 on the dynamometer I8 needs to be synchronously and continuously adjusted to enable the pull rope 11 to be always in a tensioning state, the dynamometer I8 rotates around the positioning end of the dynamometer I8 and approaches to the corresponding comparison stop I7 under the action of the pull rope 11 until the dynamometer I8 is attached to the comparison stop I7, and at the moment, when the dynamometer I8 is attached to the comparison stop I7, the touch switch 18 is just touched, the touch switch 18 is communicated, the circuit is communicated, and the indicator lamp 17 is electrified and brightened, so that the position adjustment of the dynamometer I8 is completed;
the process of adjusting the tensioning mechanism 10 on the first dynamometer 8 is consistent with the process of adjusting the tensioning mechanism 10 on the second dynamometer 15, when the tensioning mechanism 10 pulls and stretches the small arm of the male frog through the pull rope 11 and the hoop sleeve 9, the reading of the first dynamometer 8 is read at the moment, namely the maximum force of the small arm of the male frog, and the arm force of the male frog at the position can be accurately measured through the adjustable large-arm force measuring mechanism and the adjustable small-arm force measuring mechanism in the whole measuring process, so that the measuring error is reduced, the mating ability of the male frog in embracing is better understood, and the optimal yield increasing task of frog culture is improved;
In addition, when the large-arm force measuring mechanism is adjusted, the large arm of the male frog swings at a certain angle due to the pulling force of the pull rope 11, the swing can affect the position of the small arm, so that the small arm also changes at a corresponding angle, the force application direction of the small arm changes at a certain inclination angle, and the adjustable small-arm force measuring mechanism can adjust according to the change of the swing angle of the small arm caused by the swing of the large arm, so that the deviation in the force measuring process can be corrected, and an accurate value can be obtained;
similarly, the large arm swings when the small arm force measuring mechanism is adjusted, and the adjustable large arm force measuring mechanism can be used for making adaptive adjustment according to the change of the large arm.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
