Description
Technical field
The utility model relates to a kind of servicing unit of grain header maintenance, relates in particular to a kind of locking device that prevents that the ceding of Taiwan from falling suddenly, belongs to agricultural machinery technological field.
Background technology
Harvester header or propons bottom part need promote the ceding of Taiwan when damaging, and the maintenance personal could get into and overhaul below the ceding of Taiwan.Ceding of Taiwan two ends respectively are provided with a ceding of Taiwan lift cylinder; Weigh 0.6 ton-1.2 tons the ceding of Taiwan of the overhanging lifting of the piston rod of ceding of Taiwan lift cylinder; If this moment is the hydraulic system of harvesting machine catastrophic failure; Lift cylinder pressure reduces suddenly and then causes the improper whereabouts of the ceding of Taiwan, and the maintenance personal's life that is in ceding of Taiwan below receives serious threat.In view of this, adopt loop wheel machine to sling or use the steelframe of special making to hold harvester header, protection harvester header below maintenance personal's safety the ceding of Taiwan is unsettled during present most of grain header maintenance.Use loop wheel machine to increase the cost of overhaul, the special steelframe of making is not difficult to take in when not using, and it is bigger to take service clearance.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, ceding of Taiwan rising locking device that can carry at random, guarantees maintenance personal's safety.
The utility model is achieved through following technical scheme:
A kind of harvester header rising locking device; Comprise ceding of Taiwan lift cylinder, oil cylinder strut; The pole socket of the piston rod end of said ceding of Taiwan lift cylinder and harvester header downside hinge ear is hinged, ceding of Taiwan lift cylinder rear end be arranged on the cylinder barrel on the grain header front-wheel fixed head after the hinge ear hinged; Said oil cylinder strut comprises that fixed connection is integral preceding bar, the back bar that is flute profile; Preceding bar front end notch contains the piston rod end of ceding of Taiwan lift cylinder downwards, and is hinged through the lateral pin and the piston rod end of bar front end, pole socket hinge ear and piston rod end before passing across; When harvester header was elevated to upper limit, back rod rear end was resisted against on the end face of ceding of Taiwan lift cylinder drive end bearing bracket; Bar front end rear side also is provided with little pin-and-hole before said, when harvester header is reduced to lower limit, and the tilting piston rod upside of oil cylinder strut at ceding of Taiwan lift cylinder, little lateral pin passes little pin-and-hole, and little lateral pin downside is resisted against the piston rod upside.
The purpose of the utility model can also further realize through following technical measures.
Aforesaid harvester header rising locking device, wherein said back bar cross section on the bar, is fixedly connected with preceding bar before back bar front end notch is enclosed within downwards greater than preceding bar cross section.
Aforesaid harvester header rising locking device; Wherein said back rod rear end is provided with the arc bayonet socket, and back rod rear end upside is fixedly connected with quarter butt one end, when harvester header is elevated to upper limit; The quarter butt downside is resisted against ceding of Taiwan lift cylinder drive end bearing bracket upside, and the arc bayonet socket does not contact with piston rod mutually.
The utility model is contained on the pole socket hinge ear of harvester header downside, and structure is small and exquisite, very easy to use, need not use the unsettled harvester header of slinging of loop wheel machine, does not also need the special steelframe of making to hold harvester header, and use cost is low.Reliable safety guarantee is provided for the personnel of maintenance under harvester header.
Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
