Description
Technical field
The invention belongs to technical field of agricultural mechanical equipment and in particular to a kind of machinery arable land half suspension turnover plow.
Background technology
Current pivot plow is to be supported by the rear-mounted trifilar suspension of tractor, drags plough and carries out ploughing work, then by
Pivot plow is all born after tractor by lift arm, and for mobile transport pivot plow, in upset, pivot plow will for pivot plow
After completely disengaging from ground and reaching upset requirement highly, just enable to overturn, but, with development of maximizing, pivot plow is more next
Longer, weight is also being continuously increased, if the length of pivot plow is long, in lifting process, moves, be easily caused tractor after center of gravity
Disequilibrium, is difficult to manipulate, and serious meeting leads to the anterior tilting of tractor, leads to steering failure to cause the accident.
Therefore, at present, large-scale many reversed plows generally all use half suspension turnover plow, i.e. set on pivot plow
Put the support wheel setting rollover stand supporting limit deep, the plough body of pivot plow is fixed on crossbeam, and crossbeam is together with plough body around upset
Frame rotates, and realizes the upset of pivot plow, and this kind of structure, it is not necessary to tractor bears plough body and crossbeam completely, has support wheel to support,
Center of gravity is constant, tractor will not disequilibrium, be easy to manipulation it is ensured that safety.
But, existing half suspension turnover plow, rollover stand and crossbeam are two parts, complex structure, and cost is high,
And the axis of upset axis and rollover stand during crossbeam upset is usually out-of-alignment, during crossbeam upset around upset axis
For：The anterior turning supporting seat of crossbeam and rear portion are arranged on the line between the overturning pivot on rollover stand, this upset axis, often
Misaligned with swivel mount axis, this pivot point resulting on swivel mount needs to bear the weight of plough body and crossbeam during upset,
Overturning pivot is fragile, and upset axis is not coaxial with the axis of rollover stand, needs larger tilting force, and energy waste is serious, turns over
Turn difficulty, operation inconvenience.Meanwhile, the rational height of the rollover stand of existing pivot plow is not typically high, nearer apart from ground, is entering
During row farming, easily extruding is deposited between rollover stand front portion and ground straw weeds, increases advance resistance, tamper easily will be ploughed
Body lifting, it is impossible to normal farming, moves cost of transportation high, simultaneously as rollover stand is nearer apart from ground, for some ditches relatively
Deep ground, rollover stand passes through difficulty, also easily rollover stand is caused to damage.
Half current suspension turnover plow, when carrying out farming, when tractor turns around to turn it is necessary to reserve enough at the edge of a field
Long turning space, so can stay larger plot to be unable to farming at the farming edge of a field.
In addition, existing integral pivot plow relies primarily on inertia upset, that is, an overturning oil cylinder is set, during plough body upset,
Overturning oil cylinder lifts crossbeam and plough body upwards, after crossbeam and plough body climb over commanding elevation, the inertia of completely later crossbeam and plough body,
Realize latter 90 ° of upset, inertia overturns, vibration is big, easily crossbeam, plough body and tractor is damaged.
Content of the invention
In sum, in order to overcome the shortcomings of prior art problem, the invention provides a kind of half suspension turnover plow, it is
Connect a dead axle device in the tail end of crossbeam, dead axle device is capable of supporting the purpose of crossbeam, is capable of supporting again
The purpose of upset, supports crossbeam, moves it is ensured that tractor drags pivot plow safety and stability traveling, support upset, make after preventing center of gravity
Upset axis is overlapped as far as possible with crossbeam axis, reduces upset and exerts oneself, energy saving.
