Description
Technical field
The present invention relates to a kind of automatically controlled regulating device of tractor tilling depth based on driving wheel load.
Background technology
Tractor usually mounts suspension plough progress farm work by hydraulic lift hitch or is drawn by hitch frame
Plough tool carries out field cultivation operation.In order to improve the operating efficiency of tractor implement combination and reduce the change of engine load,
Frequently with resistance regulation mode, plough tool tilling depth is adjusted using the drag loading of plough tool operation as signal.
Horsepower at present, big-powered tractor have a variety of tilling depth regulative modes, such as：Position controls, draught control, and position-
Resistance Comprehensive Control energy.Wherein, in order to increase tractor set operating efficiency, prevent anthropogenic soil resistance soil increase from causing to send out
Motivation overload operation so that engine load is stablized, through commonly using resistance regulation mode.Traditional resistance regulation is to pass through measurement
Go out plough tool tillage resistance size, plough tool tilling depth is adjusted according to tillage resistance.
When drag loading is more than setting resistance, reduces plough tool tilth, reduce tillage resistance, so as to reduce tractor
Traction load so that tractor engine load is unlikely to overload；When drag loading is less than setting resistance, increase operation is deep
Degree, increases tillage resistance, keeps the stability of tractor-drawn load.Drag loading can often be detected by resistive force sensor,
In traditional mechanical drag regulator, the lower pull rod of suspension mechanism, the stress deformation of elastic pin shaft are hinged with elastic pin shaft
Reflect the size of the tillage resistance of plough tool, the displacement of resilient key at the same time by mechanical mechanism controls hydraulic control valve core, when
When resistance is big, plough tool is lifted by hydraulic control valve, reduces tilth；When tillage resistance is small, by under hydraulic control valve
Plough tool position is dropped, increases tillage resistance.It is to measure tillage resistance by dynamometry pin that automatically controlled tilling depth, which is adjusted, passes through electronic control unit
Control algolithm controls the hydraulic valve and lift cylinder of hydraulic system, so that plough tool tilth is controlled, similarly, when plough tool farming
When resistance exceedes the Resistance Setting value that electronic control unit is set, lift cylinder is controlled by electronic control unit, lifts farm implements, reduces farm implements
Tilth, when farm implements tillage resistance is less than Resistance Setting value, electronic control unit by HYDRAULIC CONTROL SYSTEM farm implements increase plough
It is deep, the traction load stabilization of tractor is kept in setting value.
The present invention proposes a kind of device of the automatically controlled adjusting of progress according to driving wheel load to tractor set tilth,
During tilling depth available for tractor Plough group is adjusted.
The content of the invention
The present invention includes the tractive resistance and driving wheel itself rolling resistance of driving wheel based on driving wheel load, therefore, drives
The load of driving wheel can more express the size of engine load, and therefore, the present invention proposes that the automatically controlled adjusting of the tilling depth of driving wheel load is
Plough tool tilth is adjusted in size according to drive wheel torque, and the tilling depth for tractor Plough group is adjusted
In.The automatically controlled Principles of Regulation of tilling depth of the driving wheel load of the present invention are to detect tooth in planetary gear speed reducing mechanism by pressure sensor
The force signals to driving axle housing are enclosed, gear ring force signals are gone out by electronic control unit acquisition testing, according to planetary gear speed reducing mechanism
Structure size and pressure sensor installation dimension calculate the driving moment of driving wheel, realize the detection to driving moment；Drag
Machine drawing driver sets driving moment upper limit value according to the attachment operating mode in wheel and farming field in electronic control unit, while automatically controlled
Unit calculates the lower limit of setting driving moment；Electronic control unit by the driving moment of detection and driving moment setting upper limit value and
Lower limit contrasts, by controlling the hydraulic cylinder of hydraulic system to adjust the tilth parameter of plough tool, when the driving wheel power of detection
When square is more than setting upper limit value, plough tool is lifted by oil cylinder, reduces tilling depth, reduces the driving moment of driving wheel, so as to reduce hair
The load of motivation；When the driving moment of driving wheel is less than preset lower limit, plough tool is declined by oil cylinder, increases tilling depth, increase
The driving moment of driving wheel, realizes that driving wheel torque is maintained at driving wheel torque setting upper limit value in cultivation operation by tractor
In the range of lower limit, so as to keep the stability of tractor engine load.
