During present invention work, tractor drives middle driving box to act by universal joint, and middle driving box drives rotary blade
The rotation of axle, the rotation of rotary knife axis drive the rotation of rotary blade, and rotary blade realizes the rotary tillage action on ground, after rotary tillage
Carry out smooth on ground, be specifically, it is when formation plate tilts forward and back or tilts, i.e., smooth using level ground as the plane of reference
When being not parallel to level ground of plate, at this time, it may be necessary to adjust formation plate, make the burnishing surface of formation plate（Where the bottom of formation plate
Plane）All the time it is parallel with level ground；When formation plate tilts backwards, i.e., the bottom on front side of formation plate is less than on rear side of formation plate
During bottom, by control angular adjustment cylinder expansion link it is flexible exemplified by, as shown in figure 5, for convenience of description, three-way four-position ratio
The oil inlet of example reversal valve one is P mouths, and the oil-out of three-way four-position proportional reversing valve one is T mouths, three-way four-position proportional reversing valve
One delivery outlet is A mouths, and another delivery outlet of three-way four-position proportional reversing valve two is B mouths, and three-way four-position ratio commutates
The left end of valve one is electromagnet one, and the right-hand member of three-way four-position proportional reversing valve one is electromagnet two, and controller controls electromagnet one
Must not be electric, electromagnet two must be electric, and P mouths are connected with B mouths, and T mouths are connected with A mouths, and vane pump suctions out the oil in fuel tank, there is pressure
Hydraulic oil adjusts the rod chamber of cylinder from P mouths by B mouths entry angle, and hydraulic oil passes through T from A mouths in the rodless cavity of angular adjustment cylinder
Mouthful be back to fuel tank, the expansion link of angular adjustment cylinder is gradually retracted, the expansion link of angular adjustment cylinder drive formation plate counterclockwise to
On turn over, the inclination of the levelness, the i.e. angle of inclination of horizontal part fore-and-aft direction and left and right directions in the real-time detection level portion of gyroscope
Angle, when horizontal part fore-and-aft direction angle of inclination for setting threshold value when, controller control electromagnet two power off, P mouths, T mouths,
A mouths and A mouths are obstructed, the expansion link stopping action of angular adjustment cylinder；When formation plate turns forward, i.e., the bottom on front side of formation plate
Less than the bottom on rear side of formation plate, it is electric that controller controls electromagnet one to obtain in portion, and electromagnet two must not be electric, and P mouths are connected with A mouths, T mouths
Connected with B mouths, vane pump suctions out the oil in fuel tank, there is nothing of the hydraulic oil of pressure from P mouths by A mouths entry angle regulation cylinder
Rod cavity, hydraulic oil is back to fuel tank from B mouths by T mouths in the rodless cavity of angular adjustment cylinder, in the rodless cavity of angular adjustment cylinder
Oil pressure is higher than the oil pressure in rod chamber, and the expansion link of angular adjustment cylinder gradually stretches out, and the expansion link drive of angular adjustment cylinder is smooth
Turned under plate clockwise direction, the angle of inclination and left and right of the levelness, i.e. horizontal part fore-and-aft direction in the real-time detection level portion of gyroscope
The angle of inclination in direction, when the angle of inclination of horizontal part fore-and-aft direction is the threshold value of setting, controller control electromagnet one is disconnected
Electricity, P mouths, T mouths, A mouths and A mouths are obstructed, the expansion link stopping action of angular adjustment cylinder, so as to the angle of formation plate fore-and-aft direction
Regulation finishes；Meanwhile formation plate is when also having inclination in the lateral direction, for example, when formation plate is tilted to the left, i.e. the right side of formation plate
Side is highly higher than left side height, if horizontal support seat is located at horizontal part center position to the right, control automatic horizontal cylinder it is flexible
Bar is retracted, and the principle of control automatic horizontal cylinder action is identical with angular adjustment cylinder, repeats no more here, and automatic horizontal cylinder stretches
Bar drives connection rotating shaft to move downward, the connection rotating shaft pressure downward to support bar, and support bar promotes horizontal support seat with front and rear
The center of support base is to lower swing, the levelness in the real-time detection level portion of gyroscope, when the angle of inclination of horizontal part left and right directions
For setting threshold value when, control automatic horizontal cylinder stopping action；When formation plate is tilted to the right, i.e. the right side of formation plate is highly low
In left side height, the expansion link of control automatic horizontal cylinder stretches out, and expansion link drives connecting seat to move up, and connecting seat drives connection
Rotating shaft is moved upwards, and connection rotating shaft hauls support bar and moved upwards, and support bar is driven on the right side of horizontal part on front and rear support base
The horizontal rotating shaft one of connection is swung up, so that the bottom of formation plate remains with level ground and is parallel to each other, not by outer
The influence of boundary's environment or tractor mode of operation, during leveling operation, when adjusting the formation plate of hypsokinesis and turning over upwards counterclockwise, bullet
Property depression bar is compressed, and plays cushioning effect；Angular adjustment terminates, and elastic pressure bar applies downward pressure to formation plate, makes smooth
Plate is close to ground all the time, improves planarization effects；During rotary tillage leveling operation, driver can be according to farmland size and agriculture
The location of machine, control hydraulic handle causes extension cylinder to stretch out or retract, to reach the purpose for adjusting smooth wide cut；The present invention
It can be realized on the ground after rotary tillage smooth, levelness of the formation plate on fore-and-aft direction and left and right directions can be adjusted in real time, made
The burnishing surface of formation plate is close to all the time and parallel to level ground, flatness is uniform, and planarization effects are good；Adjust the level of formation plate
When spending, angular adjustment cylinder will not produce torsion to connector one, when the angle of fore-and-aft direction is adjusted, around horizontal rotating shaft two
Rotate, when the angle of left and right directions is adjusted, rotated using the center of horizontal support seat as fulcrum around horizontal rotating shaft one, it is front and rear
Support base will not also produce torsion, improve the service life for the structure for being used for tightening angle regulation cylinder；The setting of elastic pressure bar, pressure
Firmly formation plate close proximity to ground, further improve planarization effects；Extending apparatus is compact-sized, can be adjusted in real time according to farmland actual conditions
Whole wide cut is flattened, meets the requirement of leveling operation；Present invention can apply in the rotary tillage leveling operation in each paddy field.
The invention is not limited in above-described embodiment, horizontal support seat, automatic horizontal cylinder etc. can also be provided at planker level
The position to the left at portion center, on the basis of technical scheme disclosed by the invention, those skilled in the art is according to disclosed
Technology contents, it is not necessary to performing creative labour can makes some to some of which technical characteristic and replaces and deform, these
Replace and deformation is within the scope of the present invention.
