Duration.
Further, rubber ring is fixed in the end that seal closure abuts with stripper loop.
Using above technical scheme, when seal closure abuts with stripper loop, at the abutted position of seal closure and stripper loop
Fixed rubber ring, further increase the sealing property between seal closure and stripper loop, plenum chamber is kept relative with plenum chamber
Independent space.
Further, the bottom fixation of starting bar surround the leg set to start rod axis.
Using above technical scheme, starting bar is started by after the contact of ground, and drives seal closure to be separated with stripper loop.
Leg is set in the bottom of starting bar, further increases the contact area on starting bar and ground.When unmanned plane contacts with ground,
Touch leg, you can drive starting bar to drive seal closure to be separated with stripper loop.
Further, shock-absorption air bag is connected by gas tube with plenum chamber, and gas tube is stereoplasm tube.
Using above technical scheme, plenum chamber is inflated by stereoplasm tube into shock-absorption air bag, and stereoplasm tube also acts as support and made
With making shock-absorption air bag be abutted with disk coal instrument lower surface.
In summary, the utility model has the advantages that：
1st, gas cylinder is fixed on support, disk coal instrument lower surface sets shock-absorption air bag, and gas cylinder passes through unidirectionally inflation group
Part is inflated into shock-absorption air bag.The starting bar of unidirectional inflatable component extends towards ground direction, when unmanned plane lands, starting bar with
Ground is contacted, and unidirectional inflatable component is opened, and is inflated into shock-absorption air bag, alleviates unmanned plane landing moment, to caused by disk coal instrument
Impact.
The 2nd, damping spring is set at the link position of starting bar and plenum chamber, reduced when starting bar starts to whole support
Caused by recoil.
