Description
Technical field
The invention belongs to the component technology fields of engineering machinery loading machine, and in particular to quick-replaceable novel height unloads grass
Fork.
Background technique
The plantation of forage is at present certain growth trend in China, and the materials such as harvested straw, stalk are put together
Secondary use can be carried out, is removed accordingly for the agricultural machinery and implement of harvested forage clamping also universal relatively shortage, similar object
Fortune, arrangement, loading and unloading are pretty troublesome, and workload is very big.With the development of farming and animal husbandry, more and more peasants and herdsmen are selected straw
Stalk, herbage etc. are pressed into bale using machinery, need that bale is carried stacking with fork careless machine in the handling process of bale, remove at present
Still based on artificial, what existing grass-trap machine unloaded highly only has 3 meters for fortune, arrangement, loading and unloading；Lifting weight is light, work
Low efficiency, it is time-consuming and laborious.More specifically, the discharge height of loading machine unloaded operation device used at present and unloading distance tool
There is certain limitation, the use scope of discharge mechanism made to become smaller, there is significant limitation, discharge height can only be improved on a small quantity,
It can not adapt to requirement higher and higher to discharge height at present and that lifting weight is big completely at all.It is unloaded at present in material to overcome
These problems present in industry are carried, goal of the invention of the invention is proposed.
Summary of the invention
For the limited technical problem of loader dump height existing in the prior art and unloading distance, mesh of the invention
Be that providing quick-replaceable novel height unloads pitch-fork, can it is larger improve loading machine discharge height and unloading distance.
The technical scheme adopted by the invention is as follows:
Quick-replaceable novel height unloads pitch-fork, and it is by handing in length and breadth that height, which unloads pitch-fork I, height unloads pitch-fork II and height unloads pitch-fork III
Wrong rib is constituted, and the height unloads that pitch-fork I unloads pitch-fork II with height respectively, height unloads pitch-fork III in being oppositely arranged, and height unloads below pitch-fork I
Connection height unloads oil cylinder I, and height, which unloads pitch-fork I and unloads pitch-fork II with height by pin shaft I, connect, and grass is unloaded with height in the fork body middle part that height unloads pitch-fork II
The fork body end portion for pitching III is hinged by pin shaft II, and height unloads pitch-fork II, height unloads pitch-fork III and is overlapped mutually along vertical direction, and height unloads
The fork body of pitch-fork I and the high fork body for unloading pitch-fork II are arranged in staggered relative, are provided with height on the high fork body for unloading pitch-fork III and unload oil cylinder
II, height unloads the piston of oil cylinder II and height unloads pitch-fork II and connects, and height unloads pitch-fork I, height unloads pitch-fork II and height unloads pitch-fork III in opposite fortune
Oil cylinder I is unloaded by height when dynamic, height unloads oil cylinder II control linkage.
Further, the height, which unloads pitch-fork I, is connected in the bent blade-shaped fork body of parallel arrangement by cross rib a by several
At structure.
Further, it is to be led to respectively by several in the L shape fork body of parallel arrangement that the height, which unloads pitch-fork II and the high pitch-fork III that unloads,
The structure that cross rib b and cross rib c are formed by connecting is crossed, the vertical portion of L shape fork body is set as arcuate structure.
Further, the fork body radian that the height unloads pitch-fork I is bent downwardly, and the height unloads pitch-fork II and height unloads pitch-fork III
Fork body radian be bent upwards.
Further, it is in be vertically arranged that the height, which unloads oil cylinder I,；Height unloads oil cylinder II in horizontally disposed.
Further, the fork body end that the height unloads the both ends pitch-fork I is provided with connecting shaft, connects high emptying below connecting shaft
Support plate is provided on cylinder I, the cross rib b for the two end yoke body staggered places that height unloads pitch-fork II, and connecting shaft passes through pin shaft I and support plate
Upper end is hinged.
Further, the height unloads and is provided with ear mount on the cross rib c of the fork body staggered place of pitch-fork III.
Further, the ear mount is set as reversed J shape structure, be affiliated to end freely extend downwards it is arc-shaped.
Further, pin shaft I and pin shaft II are fixed by locking plate.
Further, the installed position of pin shaft I and pin shaft II are provided with lubricating system.
The invention has the benefit that
Height in the present invention unloads that pitch-fork I unloads pitch-fork II with height respectively, height unloads pitch-fork III and unloads oil cylinder I and high emptying by height
Cylinder II realizes opposite movement, under the premise of not lengthening loading arm, not reducing loading machine power performance index, quickly more
Pitch-fork is changed, the discharge height of current loading machine is increased substantially by current height to 25% or more, unloads distance by improving
20% or more, making loading machine not only can guarantee lifting weight but also can improve discharge height, the present invention by the movement between pitch-fork
In height unload oil cylinder I in being vertically arranged；Height unloads oil cylinder II in being horizontally disposed with, and height unloads oil cylinder I and the high loss very little for unloading oil cylinder II,
The structure setting that height unloads pitch-fork is more compact, and closer to large arm direction, material capacity is bigger.
Height in the present invention unloads pitch-fork I, height unloads pitch-fork II and height unloads pitch-fork III planform with particularity, and work is steady
Qualitative more preferable, at low cost, performance is good, and cost performance is high, by locking plate fixed pin shaft I and pin shaft II, reduces abrasion, improves pin shaft
The problem of service life avoids and pitch-fork is connected on pull rod, the low efficiency for needing pin shaft to unload down when replacement, lube system
System is all disposed on pin shaft I and pin shaft II, and lubrication is more convenient, simply；It is faster to replace oil nozzle, the discharge time shortens, and discharging is dynamic
Make quick and strong, discharging is neat and tidy, adapts to completely at present to loader dump height increasingly higher demands.
