Contracting gas passes sequentially through the air inlet O of power takeoff gas path control valve 5, gas outlet P, the outlet T for interlocking gas path control valve 1, goes out
Port B and the air inlet C of interlocking executing agency 2 are entered in mutual lock cylinder, and piston is under the promotion of compressed air, and piston is to lock
The top movements of cylinder are kept off, the end of piston is separated with main tank gear lever upper groove, and releasing is locked to main tank gear lever, this
When, main tank gear lever carries out gear switching, and engine power passes sequentially through one axis of main tank, in main tank jackshaft, two axis and odd-side
Between axis be transmitted on power takeoff output flange, power takeoff work.
When power takeoff work terminates, closing power take-off valve, the air inlet O and gas outlet P of power takeoff gas path control valve 5 breaks
It opens, gas outlet P is connected to outlet R；Interlocking executing agency 2 in gas pass sequentially through air inlet C, gas outlet B, exhaust outlet T,
Gas outlet P and outlet R are expelled in atmosphere.
A kind of major-minor case provided by the present application interlocks gas circuit control structure, will interlock exhaust outlet and the power taking of gas path control valve
The gas outlet of device gas path control valve connects, and by the on off operating mode of two control valves of control, realizes major-minor case interlock protection function,
Simultaneously in power takeoff work, from middle position, cylinder takes gas, releases the locking of main tank, carries out operation of putting into gear, reaches power takeoff
The purpose of work.Solving the interlocking of major-minor case, the inoperable problem of power takeoff, implementation connection is succinct, dismounting convenience,
It solves the very big variation for needing vehicle and speed changer to make originally with the smallest investment, has high economic benefit and social
Benefit.
The above content is only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within protection scope with novel claims.
