Description
Technical field
The present invention relates to a kind of tractor plough tool electric-controlled intelligent system and method.
Background technology
At present, control of the tractor to plough tool mainly have two types：One kind is to suppress type, and one kind is power position tune
Nodal pattern.
Suppress the control mode of type：The lifting of plough tool realizes with descending through the hydraulic system with two-way cylinder, plough tool
Being pressed into soil and lifting can force to carry out by hydraulic system.Tractor can not only be realized and plough tool rise and fall are moved
Control, but also with float function, float function is exactly that any pressure is not present in hydraulic jack, and plough tool can be with landform
Change free movement.The various actions implementation for suppressing plough tool in type hydraulic system is controlled by a distributor, on distributor
Action bars have four positions：Upper raise-position, neutral position, lower decrease and floating bit, neutral position be position locking bit, when need realize
When plough tool rises, driving lever is stirred from the upward raise-position of neutral position, it is more to stir position, hydraulic cylinder displacement action is faster, on the contrary
It is then slower.When plough tool reaches ideal position, driving lever is reversed into neutral position, then hydraulic jack is not reoperated, and is locked in present bit
Put, so also ensure that the position of plough tool is not reoperated, be locked in ideal position；The realization and rising of decline, under needing
During drop, driving lever is stirred from the downward decrease of neutral position, stirs that position is more, cylinder action is faster, when dropping to ideal bit
When putting, driving lever is reversed into neutral position to lock position.Floating bit is from lock-bit, when needing plough tool is in quick condition
When, distributor driving lever is pushed into floating bit from neutral position, driving lever can just realize floating type with regard to that can be locked in floating bit, plough tool
State.Present tractor is to have an operation handle in driver's cabin to the mode of operation of plough tool, and operation handle passes through linkage machine
Structure is connected with the driving lever on distributor, and operation handle drives the driving lever on distributor to realize rising, decline by linkage
And float function, the realization of these actions is mainly carrys out operation handle by people.
The control mode of power position adjustment type：Effectively regulation and the position regulation of this mode band.Power regulation is exactly to pass through adjusting force
Size control tilling depth, when power is set in some value, plough tool will be pressed into from earth's surface toward internal, with press-in
The depth increase of soil, the resistance in arable land will incrementally increase, and when reaching equal in magnitude with the power that sets, tilling depth is then
Will not be further added by, become fine and close suddenly when running into soil property, when causing the resistance to increase, in order to ensure the balance of power, plough tool then understand from
It is dynamic up to lift, reduce resistance by reducing tilling depth, until the size of power of the resistance with setting reaches balance.Power is adjusted just
It is that plough tool increases or decreases resistance by increasing tilling depth or reducing tilling depth, is resistance and the size of the power set
A kind of shaping modes of balance.This shaping modes are to realize action by a mechanical force governor motion in hydraulic system
, the operation handle in operating room is connected by linkage with the regulation handle of mechanical force governor motion, and operation handle is led to
The regulation handle for crossing linkage driving mechanical power governor motion is acted, and power regulation handle is in different positions and represented not
The size of same power.Position regulation is exactly ensured in tilth, operating room with suppressing that type is similar by setting the position of plough tool
Position regulation handle be connected by linkage with the mechanical position governor motion of hydraulic system, when position regulation handle be in minimum
During position, plough tool is lifted to peak, and when position regulation handle is in maximum position, plough tool drops to minimum point.Regulation handle
In different positions, plough tool then adjusts corresponding position.Mechanical position governor motion and mechanical force governor motion are to be made in
A kind of mechanism together, needs position regulation handle being adjusted to maximum and then adjusting force regulation handle, when need when needing power to adjust
Need also exist for power regulation handle being adjusted to maximum when wanting position to adjust.
Type or power position adjustment type are either suppressed, both has the common defect to be exactly：It is cumbersome, especially
When plough tool is lifted put down again when, plough tool can not return to the position before lift, it is necessary to regulation of manually taking your time, efficiency is low,
Especially in the place that those have hard requirement to tilling depth, the influence to efficiency becomes apparent.
