Compared with prior art, the beneficial effects of the utility model are:
1) by the length adjustment of adjustable link, during installation can effective pretension shear pin, improve the reliability launched；
2) shear pin is arranged on inside discharger, is not connected with aircraft, can install shear pin the most in advance,
There is wide working place, improve the convenience of operation；
3) increasing the shearing force arm of force by connecting rod form, double-shear mode increases the shearing force of a times, it is achieved less
Shear pin diameter reaches bigger shearing force；
4) realize shear pin by the moment of torsion effect of upset torsion spring to cut off rear connecting rod and automatically downwardly turn over, reach not affect
The purpose of emission security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of adjustable link.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1～2, in this utility model embodiment, the discharger of a kind of scalable and automatically avoidance formula is sheared
Mechanism, including discharger front support 1, discharger platform 2, mounting seat 3, fixing seat 4, shear pin 5, adjustable link 6 and
Upset torsion spring 7, the bottom of described discharger front support 1 is flexibly connected discharger platform 2 by rotating shaft, props up before discharger
The fixing mounting seat 3 that connects on support 1 face relative with discharger platform 2, and mounting seat 3 connects adjustable connection by shear pin 5
One end of bar 6, the other end of adjustable link 6 vertically connects avoidance rotating shaft, and avoids rotating shaft and be movably connected in fixing seat 4,
And fixing seat 4 is fixedly connected on the surface of discharger platform 2.
It is cased with in described avoidance rotating shaft overturning torsion spring 7, and the two ends overturning torsion spring 7 are respectively fixedly connected with fixing seat 4 He
On adjustable link 6, so that receive the effect of upset torsion spring 7 elastic force when adjustable link 6 rotates, it is ensured that adjustable link
6 without being close to discharger platform 2 under the effect of external force, to reach the effect automatically avoided.
