Harvester includes tanker, framework platform and engine, and tanker is fixed on framework platform, and engine is flat positioned at rack
On platform, and it is located at the rear portion of tanker.Fig. 1 to 3 show the utility model proposes ladder structural schematic diagram.The ladder includes
Cat ladder 13, pedal 2 and handrail.
Cat ladder 13 is installed on the framework platform of harvester.Particularly, cat ladder 13 is symmetrical structure comprising bottom plate
10, ladder beam 7, crossbeam 9 and diamond plate 8.Bottom plate 10 is two, is mounted on the framework platform of harvester.Ladder beam 7 is two
It is a, it is respectively and fixedly connected on two bottom plates 10.Crossbeam 9 be it is several, be fixed between two ladder beams 7, and deposited with the engine of harvester
In certain safe distance.Diamond plate 8 be it is several, be respectively and fixedly connected on several crossbeams 9, diamond plate 8 has lablab shape decorative pattern, rises
To antiskid effect.Protective device can also be welded on ladder beam, maintenance personal is avoided to touch outside engine when climbing ladder
Surface.
Pedal 2 is installed on cat ladder 13, and is located above the engine of harvester, with engine exist certain safety away from
From.Particularly, which further includes bracket 12, and bracket 12 is installed on the rear portion of grain box of harvester, cat ladder 13 and pedal 2
One end is overlapped on bracket 12, and is bolted to connection.Multiple long waist shaped holes, the week in long waist shaped hole are offered on pedal 2
Side has perpendicular folded plate, and perpendicular folded plate effectively strengthens the intensity of pedal.Notch with Wave crest and wave trough on perpendicular folded plate, multiple notches have
Increase antiskid effect to effect.
Handrail is collapsibly installed on the side of pedal 2.Particularly, handrail includes pipe beam 5, lower pillar stand 4, upper handrail 1
With pin 6.Pipe beam 5 is fixed in the side of pedal 2, and lower pillar stand 4 penetrates in pipe beam 5, and upper handrail 1 is hinged with lower pillar stand 4, and pin 6 runs through
The lower part of pipe beam 5 is pierced by with limiting lower pillar stand 4 from the bottom of pipe beam 5.The length of lower pillar stand 4 is less than the top of pipe beam 5 to pin 6
Distance.The outer diameter of lower pillar stand 4 and upper handrail 1 is less than the internal diameter of pipe beam 5, can guarantee lower pillar stand 4 and upper handrail 1 in pipe beam 5
When inside moves up and down there are lesser gap and also there is no interference.Further, handrail is symmetrical structure, has two
A pipe beam 5 and two lower pillar stands 4, upper handrail 1 are in inverted u-shaped.The lower part of upper handrail 1 opens up flat-ended protrusions, and high spot is equipped with circle
Hole.The top of lower pillar stand 4 is equipped with flat notch, and notch both ends part is equipped with circular hole.The lower part circular hole of upper handrail 1 passes through rivet
It is riveted with the top circular hole of lower pillar stand 4, rotate handrail 1 can around rivet relative to lower pillar stand 4.The ladder further includes deck
11, deck 11 is installed on the other side of pedal 2, and folded handrail (i.e. upper handrail) is connected in deck 11, plays locking effect
Fruit.Further, deck 11 can be made of rubber, and have certain elasticity.The top of deck 11 is provided with half round cut, and half
The round heart is lower than the upper end of deck 11.When upper handrail 1 falls into the notch on 11 top of deck, handrail 1 can be effectively blocked.
Fig. 1 show the utility model proposes ladder fold when structural schematic diagram.At this point, handrail is in folded state,
Upper handrail is fallen into deck, and the lower part of the hinged lower pillar stand in its underpart is fallen into Guan Liang, and the axis of upper handrail and lower pillar stand is in 90
Degree, so that handrail be made to be in restrained condition in left and right, upper and lower position.
Fig. 3 show the utility model proposes ladder work when structural schematic diagram.At this point, handrail is in running order,
Upper handrail leaves deck, and upper handrail is coplanar with lower pillar stand, and the hinged lower pillar stand in its underpart is fallen completely in Guan Liang, under upper handrail
Portion is also fallen into Guan Liang, so that handrail be made to be in restrained condition in left-right position.The bottom of lower pillar stand will be in contact in pin,
Pin supports lower pillar stand, prevents it from falling.At this point, ladder is climbed up in maintenance personal's climbing, stands when on pedal, can help and help
Hand crosses engine, arrives at tanker, overhauls to tanker inner part.To avoid maintenance personal station on ladder without dependence,
There is a problem of personal safety danger.
The utility model proposes harvester include above-mentioned ladder structure.It, can be in harvester transport and when transition operation
The handrail of ladder is folded, upper handrail is connected in deck, makes its locking, so that the complete machine height of harvester be effectively ensured, keeps away
Exempt from superelevation and a series of parts damages problems of bring.
Above embodiments are only to illustrate the technical solution of the utility model, not are used to limit the implementation of the utility model
Range.In every case it is practical new to be all deemed to fall this for done equivalence changes and modification within the protection scope of the present utility model
In the protection scope of type.
