In the fixed seat 7 of oil cylinder 2.
In a preferred technical scheme, described harvester oil cylinder stroke limit safety device also includes spacing jump ring
6, described spacing jump ring 6 is arranged on front and rear each one of fixed seat 7, it is ensured that the axis of bolt fixed seat 5 and telescopic oil cylinder 2 is put down
OK.
In a preferred technical scheme, one end of described telescopic oil cylinder 2 passes through bearing pin 8, packing ring 9, split pin 10
It is connected with the delivery chute of harvester；The other end of described telescopic oil cylinder 2 passes through bearing pin 8, packing ring 9, split pin 10 and harvester
Chassis be connected.
In a preferred technical scheme, described regulating bolt 3 is fixed on bolt fixed seat 5 by adjusting nut 4
On.
In a preferred technical scheme, described bolt fixed seat 5 is fixed on flexible by fixing axle 12, jump ring 11
In the fixed seat 7 of oil cylinder 2.
According to the above-mentioned technical solution, there is harvester oil cylinder stroke limit safety device of the invention following technology to imitate
Really：Contacted by regulating bolt with limit base, be locked telescopic oil cylinder, it is impossible to carry out contractive action, also will not be because of hydraulic pressure system
System failure and he falls to causing suddenly to damage, and when being repaired, serve the effect of protection personnel's personal safety.
