Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly relates to a kind of four bar folding buffered devices.
Background technology
Along with the development of agricultural machine, large-scale integrated planting agricultural machinery is applied more and more extensive in agricultural planting operation. At present, four bar device operation strategies are generally lifts lighter object, and just in tractor elevating gear on agricultural machinery, lift cylinder is arranged on the inner chamber of tractor, do not possess folder function, maintenance is inconvenient, the rear overhang lifted is excessively long, especially after the mechanical connection of integrated planting, length, greatly between 4-5 rice, is lifted and is relied on tractor dynamic power relatively big in process, promote connecting rod and rise more difficult by machinery, in decline process, surging force is bigger, it is easy to being that four bar devices damage, performance is lifted in impact.
Practical novel content
Technical problem to be solved in the utility model is to provide one and possesses folder function, easy to maintenance, lifts rear overhang shorter, promotes performance good, reduces four bar folding buffered devices of surging force.
For solving the problem, a kind of four bar folding buffered devices described in the utility model, comprise upper arm frame, lift cylinder, connecting arm and folding bar, it is characterised in that: described upper arm frame top is provided with the oil cylinder connecting rod of inclination downwards, and its two curb girders opposite position installs connecting arm respectively; Described oil cylinder connecting rod middle position is by lift cylinder described in pinned connection; Described both sides connecting arm relative position is fixed with crossbeam; Described crossbeam mid-way is had and the lifting arm of described oil cylinder connecting rod reverse direction by pinned connection; Described lift cylinder end is by promoting arm described in pinned connection; Described connecting arm end is by bar folding described in pinned connection, and this folding bar top is provided with lug boss; The support bar matching by pin-and-hole and regulating it is connected with bearing pin outside described connecting arm; Described connecting arm top is provided with the pressure spring corresponding with described lug boss; Described connecting arm is connected with buffering cross bar near the opposite position place of pressure spring, and this buffering cross bar middle position is provided with buffer spring.
Described oil cylinder connecting rod low side is connected to described crossbeam mid-way, and corresponding with described lifting arm link position.
Described lug boss width is less than described connecting arm width, and identical with the diameter of described pressure spring.
Described buffer spring is corresponding with described lifting arm upper-lower position, and described buffer spring diameter is identical with described lifting arm width.
The utility model compared with prior art has the following advantages:
The utility model is owing to being provided with lift cylinder, and lift cylinder promotes arm by pinned connection, and both sides connecting arm end is by bar folding described in pinned connection, pass through lift cylinder, lifting arm can be promoted so that it is possess folder function, easy to maintenance, lift rear overhang shorter, lifting performance is good, and meanwhile, after promoting, pressure spring contacts with lug boss, after landing, buffer spring is with promoting arm contact, reduces decline surging force.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1. upper arm frame, 2. oil cylinder connecting rod, 3. connecting arm, 4. lift cylinder, 5. crossbeam, 6. promote arm, 7. folding bar, 8. lug boss, 9. support bar, 10. pressure spring, 11. buffering cross bars, 12. buffer springs.
Embodiment
As shown in Figure 1, a kind of four bar folding buffered devices, comprise upper arm frame 1, connecting arm 3, lift cylinder 4 and folding bar 7, and upper arm frame 1 top is provided with the oil cylinder connecting rod 2 of inclination downwards, and its two curb girders opposite position installs connecting arm 3 respectively; Oil cylinder connecting rod 2 middle position is by pinned connection lift cylinder 4; Both sides connecting arm 3 relative position is fixed with crossbeam 5; Crossbeam 5 mid-way is had and the lifting arm 6 of oil cylinder connecting rod 2 reverse direction by pinned connection; Lift cylinder 4 end promotes arm 6 by pinned connection; Connecting arm 3 end is by the folding bar 7 of pinned connection, and this folding bar 7 top is provided with lug boss 8; With crossbeam 5 opposite position by pinned connection support bar 9 outside connecting arm 3, its top is provided with the pressure spring 10 corresponding with lug boss 8; Connecting arm 3 is connected with buffering cross bar 11 near pressure spring 10 position, and this buffering cross bar 11 middle position is provided with buffer spring 12.
During use, being connected with tractor traction apparatus by upper arm frame 1, lift cylinder 4 is connected tractor, promotes arm 6 and is connected in required frame with folding bar 7 end, when in lift cylinder 4 lifting process, by crossbeam 5 as basic point, arm 6 pull-up will be promoted, simultaneously, by connecting arm 3 end as basic point by folding bar 7 also pull-up, folding with connecting arm 3, owing to action of gravity makes folding bar 7 fall after folding, lug boss 8 drops on pressure spring 10; When, in lift cylinder 4 landing process, lifting arm 6 and folding bar 7 decline simultaneously, the decline gravity promoting arm 6 is cushioned by buffer spring 12, decreases the surging force of whereabouts.
